This
section describes the legislation and guidelines that have been reviewed in the
Landscape & Visual Impact Assessment (LVIA). The landscape baseline reviews
the condition of existing landscape resources (LRs) and landscape character
areas (LCAs), planning and development control framework, and the visual
amenity and visually sensitive receivers (VSRs).
The
assessment identifies landscape and visual impacts that would occur during the
construction and operational phases for the Lok Ma Chau (LMC) Loop Development proposals including the infrastructure
and Designated Projects (DP) comprising the Ecological Area (DP1); Western
Connection Road (WCR) (DP2); Direct Link to Mass Transit Railway (MTR) LMC
Station (DP3); Drainage System under Internal Transport Networks (DP4); Sewage
Treatment Works (DP5); Eastern Connection Road (ECR) (DP6); and Flushing Water
Service Reservoir (DP7) and planned institutional development on LMC Loop and
its associated infrastructure and utilities. Details are described in Chapters
1 and 2 of the EIA Report. The LVIA recommends landscape mitigation measures to
alleviate the predicted impacts and identifies residual effects apparent after
mitigation. The LVIA has been conducted in accordance with the requirements of
Annexes 10 and 18 of the TM-EIAO as well as the requirements set out under
Clause 3.4.10 of the EIA Study Brief.

11.3 Review of Planning and Development Control Framework
A review
of the existing planning studies and documents has been undertaken to gain an
insight into the planned role of the site, its surrounding areas, and its
landscape context and to help to determine if the project fits into the wider
existing and future landscape context. The assessment does not consider all of
the areas zoned on the Recommended Outline Development Plan (RODP) but focuses
on the areas affected by the proposed works. The compatibility of the proposed works and
the planned developments either within or adjacent to the assessment area is
also considered in terms of the landscape and visual impacts. The locations of these areas are shown on Figures 11.1a
to 11.1e. This review has considered the
following aspects of the identified planning designations:
·
Zoning
areas which would be physically affected by the proposals, that is where the
implementation of the proposed works would lead to the actual loss of an
area;
·
The
degradation of the landscape setting of an area which might affect the
viability of its landscape planning designation but not result in a loss of
zoning area;
·
The
visual amenity enjoyed by future residents or users; and
·
The
general fit of the proposals into this future landscape.
The
assessment covers areas on the following Outline Zoning Plans (OZPs) and the draft Development
Permission Area (DPA) Plan
having interfaces with the LMC Loop development:
·
No. S/YL-ST/8: Approved San Tin OZP
·
No. S/YL-NTM/12:
Approved Ngau Tam Mei OZP
·
No. S/NE-KTN/8: Approved Kwu Tung North OZP, and
·
No. DPA/NE-MTL/2: Approved Ma Tso Lung and Hoo Hok
Wai DPA Plan.
The LMC Loop is not currently covered by
any statutory plans. The development
proposal for the LMC Loop will be incorporated into a statutory town plan upon
completion of the study. As the proposed ECR, WCR, the Direct Link to MTR LMC Station and the
Flushing Water Service Reservoir will involve land
requirement which is outside of the LMC Loop and covered by various zonings on the current statutory town plans, the planning intention of the
respective zonings on the concerned OZPs/DPA
Plan will be duly considered and followed:
·
Small portion not
more than 2.5% of “Conservation
Area” (“CA”) Zone to the east of MTR
LMC Station, at Ha
Wan Tsuen and along the Ha Wan Tsuen Road will be in conflict with the proposed road works of the WCR (DP2) and Direct Link to MTR LMC Station (viaduct) (DP3).
·
Small portion not
more than 0.5% of “CA” Zone to the north of
Ping Hang will be in conflict with the construction of depressed and underpass
road sections of ECR (DP6).
·
Some
of the proposed road / viaduct works of Direct Link to MTR LMC
Station (DP3) will encroach upon the “Other Specified Uses” (“OU”) Zone at the MTR LMC
Station. Small portion not more than 10% of this zone will be affected.
·
Some
of the proposed road works of WCR (DP2) will encroach upon the “Undetermined” (“U”) Zone along LMC Road located to the east of
LMC BCP (not more than 3% of this zone ) and
“Open Storage” (“OS”) Zone located between San Tin Highway and Kwu Tung Road
(not more than 0.5% of this zone ).
·
“Green Belt” (“GB”) Zones located to the east and west of the LMC Road (not more than 1.33% of this zone ) will also be encroached upon by
the proposed road works of the WCR (DP2).
·
“GB” Zones located to the north-east of Tse Koo
Hang will be encroached upon by the proposed at-grade section of the ECR (DP6)
(not more than 0.05% of this zone ).
·
“GB” Zones located at Ping Hang will be in conflict with the proposed Flushing
Water Service Reservoir (DP7) and
associated access road from the Boundary Patrol Road. (not more than 0.15% of this zone ).
·
“Agriculture”
(“AGR”) Zone located at Ma Tso Lung Sun Tsuen will be encroached upon by the
proposed at-grade section of the ECR (DP6) . The “AGR” zone located at Shun Yee
San Tsuen will not be affected by the proposed works. (not more than 4.6% of
this zone ).
·
Some of the
proposed road works of the ECR (DP6) will encroach upon to the “ OU”
(Eco-lodge) Zone located to the west of Tse Koo Hang. Some of the proposed road
works of the ECR will encroach upon to the “Unspecified Use” Zone located at
Hoo Hok Wai fish pond areas. (not more than 0.6% of this zone ).
Given
the above summary and detailed review in Table
11.3.1, the proposed works with mitigation measures including responsive
building and structural design, road layout and new tree planting largely fit
within the planning and development control framework and can be integrated
within the future outlook of the landscape and visual context.

“Conservation
Area” (“CA”) |
This zone encompasses the fish pond
areas surrounding the southern edge of LMC Loop and Shenzhen River. Fish ponds located immediately
east of Mai Po Tsuen also under cover of this zone. The planning intention of
this zone is to conserve the ecological value of wetland and fish ponds which
form an integral part of the wetland ecosystem in the Deep Bay Area. The
wetland and fish ponds functions as a substantial source of food
supply for birds and as an important habitat for roosting and foraging of
water birds. |
The proposed works within the LMC Loop
will be away from this zone. However the proposed ECR and WCR (Sections of Ha
Wan Tsuen Road and Ping Hang) and Direct Link to MTR LMC Station will be
located within this zoning area and some portion of the area will be acquired
due to the road extension works. 5.5 / 183.06 ha. (3%) Magnitude: Small |
Due to the extension works of the
proposed ECR and WCR, and Direct Link to MTR LMC Station (viaduct) a portion of areas will be affected.
Some of the mature trees and significant/important trees along the eastern side of Ha Wan
Tsuen Road, some trees located around fish ponds to the
north of Ha Wan Tsuen and some trees in mitigation wetland located to the
east and within the MTR LMC Station would
be affected. It would also lead to the loss of the existing trees and
vegetation, fishponds and mitigation wetland. Some mitigation proposals including the
implementation of off-site compensation of trees and reinstatement of
fishpond areas would be incorporated. |
“Green Belt” (“GB”) |
This zone covers the areas of Ping
Hang, Tai Law Hau and areas to the north east of Pun Uk Tsuen and Chau Tau
Tsuen. The planning intention of this zone is to define the limits of urban
and sub-urban development areas by natural features and to contain urban
sprawl as well as to provide passive recreational outlets. |
A portion of the existing Lok Ma Chau
Road located
within this zone will be acquired for the construction of WCR. A portion of the existing Boundary
Patrol Road to the west of Lin Ma Hang will be acquired for the construction of ECR and the
access to the Flushing Water Service Reservoir. A portion
of grassed Horn Hill to the south of HKPF Lok Ma Chau Operation Base will be
acquired for the construction of the proposed Flushing Water Service
Reservoir. 2.5 / 188.62 ha. (1.3%) Magnitude: Small |
Given that some portions of the
existing roads and the vegetated areas alongside the road and grassed
knoll within
the zone will be affected, mitigation measures are thus considered to
minimise impacts. The main mitigation measures include the preservation of
existing roadside trees; and new tree and shrub planting alongside the
proposed WCR and ECR. The mitigation measures for the Flushing Water Service Reservoir include semi-sunken
built structures, tree and shrub planting and hydroseeding on sloping areas. |
“Other
Specified Uses” (“OU”) (Railway
Terminus and Public Transport Terminus) |
This zone covers the
areas of MTR LMC Station and its associated LMC BCP and PTI. The planning intention of this zone is
to provide land for the development of the MTR East Rail Extension LMC
Railway Terminus and public transport interchange. |
The proposed works within the LMC Loop
and the ECR and WCR
will be located away from this zone. However, the existing PTI at MTR
LMC Station
located within this zone area will be acquired for the construction of the
proposed Direct Link to MTR LMC Station (viaduct).. 0.66/ 6.37 Ha. (10%) Magnitude: Small |
The proposed Direct Link
to MTR LMC Station
will utilize the existing PTI
within this zone for the construction of viaduct and elevated
connection to existing LMC Station and PTI. The construction works with
mitigation measures are thus considered to minimise impacts. The main mitigation measures
include the off-site transplanting of existing roadside
trees. |
“Undetermined” (“U”) |
This zone located to the north of the
Fanling Highway, east of San Tin Tsuen Road and south of Chau Tau Tsuen. It
is intended to provide an area for the Spur Line and the proposed Northern
Link railway system. |
The proposed works within the LMC Loop
and the ECR will be located away from this zone. However, the existing Lok Ma
Chau Road and section of San Tin Highway located within this zone area will
be acquired for the construction of the proposed WCR. 0.78/ 25.56 ha. (3%) Magnitude:
Small |
The proposed WCR will utilize the
existing Lok Ma Chau Road and a section of the San Tin Highway within this
zone, with construction works carried out along the roads. The construction
works with mitigation measures are thus considered to minimise
impacts.
The main mitigation measures include the preservation of existing roadside
trees; and new tree and shrub planting alongside the proposed WCR. |
No. S/YL-NTM/12: Approved Ngau Tam Mei
OZP |
|||
“Open Storage” (“OS”) |
This zone located to the south of
San Tin Highway and along sides of Kwu Tung Road. It is intended for the
provision of land for appropriate open stage uses and to regularize the
already haphazard proliferation of open storage uses. |
The proposed works within the LMC Loop
and the ECR will be located away from this zone. However, a section of San Tin Highway and Kwu
Tung Road located
within this zone area will be acquired for the construction of the proposed
WCR. 0.5/ 91.81 ha. (0.5%) Magnitude:
Very Small |
The proposed Lok Ma Chau
Road/San Tin Highway Connection of the WCR
will utilize the existing Lok Ma Chau Road and a section of the San Tin
Highway within this zone, with construction works carried out along the
roads. The construction works with mitigation measures are thus considered to minimise
impacts.
The main mitigation measures include the preservation of existing roadside
trees; and new tree and shrub planting alongside the proposed WCR. |
No. S/NE-KTN/8: Approved Kwu Tung
North Outline Zoning Plan |
|||
GB |
This zone covers the areas to the
north west of Fung Kong Shan. The planning intention of this zone is to
define the limits of urban and sub-urban development areas by natural features
and to contain urban sprawl as well as to provide passive recreational
outlets. |
The at-grade section of the proposed
ECR under this Study will
terminate to the north of the Kwu Tung North OZP and so there will be no
impact on the zoning within this area. 0 / 107.23 ha. (0%) Magnitude: Nil |
As the proposals will not impact upon
this zone there is no requirement for mitigation. |
No. DPA/NE-MTL/2: Approved Ma Tso Lung and Hoo Hok Wai Development Permission
Area Plan |
|||
GB |
This zone covers the areas to the north-east of
Tse Koo Hang and to the north-west of Shun Yee San Tsuen. The
planning intention of this zone is to define the limits of urban and
sub-urban development areas by natural features and to contain urban sprawl as
well as to provide passive recreational outlets. |
The at-grade section of the proposed
ECR will be located at the eastern edge of this zone. This portion will be acquired for the
construction of ECR and the associated slope works. 0.5/ 217.75 ha. (0.2%) Magnitude: Very Small |
A small portion of the area within
this zone will be acquired for the ECR and associated slope works. The
vegetated slope and areas affected by the works will be reinstated with the roadside
planting of new trees and shrubs to enhance the sense of integration and
minimising impacts on the adjacent areas. Therefore the proposed works are
considered to be consistent with the planning intention of this zone. The
proposed mitigation measures also include the preservation of existing
vegetation. |
“Agriculture” (“AGR”) |
This zone covers the areas of Shun Yee San Tsuen
and Ma Tso Lung Sun Tsuen. It intended to retain and safeguard good-quality agricultural
lands / farms / fish ponds for agricultural purposes. It is also intended to
retain fallow arable land with good potential for rehabilitation for
cultivation and other agricultural purposes. |
The at-grade section of the proposed
ECR will be at the existing village settlements within this zone. This
portion will be acquired for the construction of the proposed ECR and the
associated slope works. 1.77 / 38.42 ha. (4.6 %) Magnitude: Small |
The disturbance to these areas will
include the existing vegetation within the agricultural fields at Fung Kong
Shan and the lower vegetated slopes near Ma Tso Lung. There would also be an
impact on the mature tree clusters within the village settlement. Mitigation
measures include the preservation of existing tree clusters through the local
fine turning of the road alignment. Other measures include the reinstatement
of the roadside and rural landscape through the provision of new roadside
landscape areas. This includes lining the road with new tree and shrub planting.
With implementation of the proposed mitigation works the proposed development
within this zoning area is considered to be consistent with the planning
intention. |
“Other Specified Uses” (“OU”) (Eco-lodge) |
This zone covers the small knoll to the west of
Tse Koo Hang. It intended to provide land for sustainable-based tourism in
form of an eco-lodge for development of low-rise, low-density resort type
accommodation. |
The proposed works within the LMC Loop
and the WCR will be located away from this zone. However, proposed at-grade section of the proposed ECR
will be located within this zone. A small portion of area alongside of existing
Boundary Patrol Road will
be acquired for the construction of the ECR. 0.06 / 9.15 ha. (0.6%) Magnitude: Very Small |
Given that some portions of the
existing road and the vegetated areas alongside the road will be affected,
mitigation measures are thus considered to minimise impacts. The main
mitigation measures include the preservation of existing roadside trees; and
new tree and shrub planting alongside the proposed ECR. |
“Unspecified Use” |
This zone covers the Hoo Hok Wai fishpond areas
located to the north of existing Boundary Patrol Road. The planning intention
of this zone is to conserve and enhance the ecological value and functions of
the existing fish ponds and wetland in interim, pending a detailed study on
the development content to be undertaken in the future. |
The at-grade section of the proposed
ECR will be located at the southern
edge of this zone. This portion will
be acquired for the construction of ECR and the associated slope works. 0.85 /246.32 ha. (3.4%) Magnitude: Small |
A small portion of the area within
this zone will be acquired for the ECR and associated slope works. The
vegetated slope and areas affected by the works will be reinstated with the
roadside planting of new trees and shrubs to enhance the sense of integration
and minimising impacts on the adjacent areas. Therefore the proposed works
are considered to be consistent with the planning intention of this zone. The
proposed mitigation measures also include the preservation of existing
vegetation. |
11.4.1 Landscape
The assessment
of the impacts of a proposed scheme on the existing landscape comprises two
distinct sections namely the baseline survey and the landscape impact
assessment. Landscape Impact Assessment
(LIA) assessment area has been undertaken to include all areas within 500m
of the site boundary within HKSAR in accordance with the EIA Study Brief.
A
baseline survey of the existing landscape resources and
landscape character has been undertaken
based on a combination of desktop studies and site surveys. The landscape
elements which contribute to the landscape character include:
·
Local topography and geology;
·
Woodland extent and type;
·
Other vegetation types;
·
Built form;
·
Patterns of settlement;
·
Land use;
·
Scenic spots;
·
Details of local materials, styles, streetscapes,
etc.;
·
Prominent watercourses and water bodies; and
·
Cultural and religious features.
The
process of landscape characterisation draws on the information gathered in the
desktop and site survey and provides an analysis of the way in which the
elements including the identified Landscape Resources (LRs)
interact to create the character of the landscape. The assessment area is then
divided into broadly homogenous units of similar character, which are called Landscape Character Areas (LCAs).
The sensitivity of
the individual LRs and LCAs is rated using low, medium or high depending on the
following factors:
·
Condition,
quality and maturity of the LRs / LCAs (maturity in this context refers to the
age of the LR or LCA relative to its
constituent components therefore a woodland containing mature trees would be
considered to have a high level of maturity);
·
Importance
and rarity of special landscape elements (rarity being of either local,
regional, national or global importance) ;
·
Significance
of the LRs / LCAs from a local and regional perspective (therefore the
sensitivity of a LR or LCA which is either rare in a local or regional context
is greater than one which is common place);
·
Ability
of the LRs / LCAs to accommodate change; and
·
Statutory
or regulatory requirements relating to the landscape including its resources.
The next stage of
the assessment process is the identification of the assessment of the magnitude
of change (rated as nil, small, intermediate or large) arising from the implementation
of the project and the principal sources of impact based on the following
factors:
·
Scale of the works and the associated supporting
facilities;
·
Compatibility of the project with the surrounding
landscape;
·
Duration of impacts (temporary or permanent) under
construction and operation phases; and
·
Reversibility of change.
The degree of significance of landscape impact is derived from the magnitude of change which the project will cause to the LRs / LCAs and the sensitivity of the LRs / LCAs. This makes a comparison between the landscapes, which would have existed in the absence of the Project with that predicted as a result of the implementation of the project. The significance threshold for impacts to LRs and LCAs is rated as significant, moderate, slight or negligible. The impacts may be beneficial or adverse.
The assessment of
the impacts of a proposed scheme on the existing landscape comprises two
distinct sections namely the baseline survey and the LIA. The assessment area for the LIA includes all
areas within 500m of the site boundary of the Project which are within HKSAR in
accordance with Section 3.4.12.2 of
the EIA Study Brief (ESB-238/2011).
A baseline survey
of the existing landscape resources and landscape character has been undertaken
based on a combination of desktop studies and site surveys. LRs and LCAs have
been identified in Section 11.5. In
addition, the sensitivities of individual LRs and LCAs have been assessed and
presented in Section 11.5.
The significance threshold is derived from the matrix as shown in Table 11.4.1.

11.4.1.1 Tree Survey Methodology
A broad
brush group tree survey has been undertaken to minimize conflicts with existing
vegetation and inform the assessment of the impacts as part of the LVIA. The
tree survey involves the identification of tree groups within the proposed
works area determining for each the range of tree species, tree sizes, health
condition, form, and amenity value and their treatment as a result of the
implementation of proposed works.
This
existing tree data allows the fine tuning of the detailed design for the
proposed works and ensures that any significant
trees including potential OVTs or rare or protected tree species, will where
possible, be protected in their current location or through transplantation
during both the construction and operational phases of the Project.
In addition to the
broad brush tree survey information concerning the other vegetation cover
within the assessment area refers to flora survey description in Chapter 12
Ecology Impact Assessment.
11.4.2 Visual
The
assessment of the visual impact of the scheme comprises two distinct parts:
·
Baseline survey; and
·
Visual impact assessment which includes the
identification of the sources of visual impact, and their magnitude, that would
be generated during construction and operation phases of the proposed works;
and identification of the principal visual impacts primarily in consideration
of the degree of change to the baseline conditions.
The
assessment area for the Visual Impact Assessment (VIA) is defined by a Visual
Envelope (VE) within the HKSAR which includes all areas from which the proposed
works can be seen, or the area which forms the view shed. This is shaped by
natural / manmade features such as existing ridgelines, built development and
for example areas of woodland / large trees. The VE is identified through a
combination of detailed walkover surveys, and desk-top study of topographic
maps and photographs, and the preparation of cross-sections to determine
visibility of the improvement works from various locations.
The
baseline survey for all views towards the proposals is undertaken by
identifying:
·
The
Visual Envelope (VE) and Zone of Visual Influence (ZVI) as have been described above and where the
proposals may be contained either wholly or partially within views. This must
also include indirect effects such as offsite construction activities and
temporary works; and
·
The
Visually Sensitive Receivers (VSRs) within the VE whose views will be affected by the scheme.
The
potential receivers are considered as four groups:
·
Views
from residences – the most sensitive of receivers due to the high potential for
intrusion on their visual amenity and quality of life;
·
View
from workplaces – less sensitive than above due to the visual amenity being
less important within the work environment;
·
Views
from recreational landscapes – including all areas apart from the above, e.g.,
public parks, recreation grounds, footpaths, cultural sites etc. and the sensitivity
of this group depends on the length of stay and nature of activity, e.g.
sitting in a park as opposed to an active sporting pursuit; and
·
Views
from riverside access, public roads and railways – including vehicle travellers
with transitory views.
The
assessment of sensitivity has also been based on the quality and extent of the
existing view. Therefore a view from a residential property, which would
normally be considered the most sensitive view, may be less so if for example
it is degraded by existing development or partially screened by intervening
visual obstacles such as existing vegetation. Factors affecting the sensitivity
of receivers for evaluation of visual impacts include:
·
Value
and quality of existing views;
·
Availability
and amenity of alternative views;
·
Type
and estimated number of receiver population;
·
Duration
or frequency of view;
·
Degree
of visibility; and
·
Views
available to the identified VSRs are rated according to their sensitivity to
change using low, medium or high.
The location
and direction of its view relative to the scheme also influences the
sensitivity of each group. Typical viewpoints from within each of the visually
sensitive groups are identified and their views described. Both present and
future (planned) visually sensitive receivers (PVSRs), if any, are considered.
The
factors affecting the magnitude of change for assessing the visual impacts
include the following:
·
Scale
of the works and the associated supporting facilities;
·
Compatibility
of the project with the surrounding landscape forming the view extent of
visibility (level of potential blockage of the view);
·
Viewing
distance;
·
Duration
of impacts under construction and operational phases; and
·
Reversibility
of change.
The
magnitude of change to the views will be classified as follows:
·
Large:
e.g. large project works extent / extensively blocked the views of VSRs /
Project nature is not compatible with existing visual context / works area
located in the foreground of the visual context / permanent impacts /
irreversible of change;
·
Intermediate:
e.g. intermediate project works extent / partially blocking the views of VSRs /
project nature is fairly compatible with existing visual context / works area
located in the middle ground of the visual context and not immediately adjacent
to VSRs and/or their views are already partially screened by existing
topography, built structures or vegetation / permanent impacts/ irreversible of
change;
·
Small:
e.g. small project works extent / no blockage of views / project nature is
compatible with the existing visual context / works area located at distance
from VSRs / permanent impacts and duration of construction impacts is short /
irreversible change or temporary change of view; and
·
Nil: e.g. no discernible change in visual context.
The significance threshold for visual impact is rated in a similar fashion to the landscape impact, i.e. significant, moderate, slight and negligible. The impacts may be beneficial or adverse.
Therefore
the impact is derived from the magnitude of change, which the project will
cause, to the existing visual context and the sensitivity of VSRs. The
significance threshold is derived from the following matrix in Table 11.4.2.

cause a barely perceptible deterioration or improvement in the existing
landscape quality or visual amenity. |
Negligible |
No discernible change in the existing landscape quality

The purpose of mitigation is to avoid, reduce, and where possible remedy or offset any adverse effects on the environment arising from the proposed works. The ideal strategy for identifiable adverse impacts is one of avoidance. If this is not possible, alternative strategies of reduction, remediation and compensation should be explored.
Mitigation measures may be considered under two categories:
· Primary mitigation measures that intrinsically comprise part of the identification of proposed works through an iterative process and this form of mitigation is generally the most effective; and
· Secondary mitigation measures designed to specifically address the remaining (residual) adverse effects arising from the proposed works.
Primary mitigation measures form integrated mainstream components of the proposed works focusing on the adoption of alternatives to the buildings and structures, and refinements to the basic engineering and architectural design including layout, built structures etc. to avoid and / or minimize potential adverse impacts. The design philosophy can also describe the benefits to the design of alternative solutions, introduced to reduce potential adverse impacts, and indicate how these have been addressed.
Secondary mitigation measures are specifically designed to mitigate the adverse impacts of the proposed works and are considered in the assessment of the landscape and visual impacts, these may take the form of remedial measures such as colour and textural treatment of built structure; and compensatory measures such as the implementation of landscape design measures (e.g. tree planting, creation of new amenity area and reinstatement of marsh land etc.) to compensate for unavoidable adverse impacts and to attempt to generate potentially beneficial long-term impacts.
11.4.4 Residual Impacts
The residual impacts are those, which remain after
the proposed mitigation measures, have been implemented. This has been assessed
both during the construction period, Day 1 during operation period and during
the design year, which is often taken to be 10 to 15 years after the proposed
scheme has been opened to normal operation when the soft landscape mitigation
measures are deemed to have reached a level of maturity, which allows them to
perform their original design objectives.
The level of impact is derived from the magnitude
to change, which the project will cause to the LRs / LCAs taking into account
the beneficial effects of the proposed mitigation and the sensitivity of LRs /
LCAs. The significance threshold is derived from the matrices described
separately above for the landscape and visual impacts.
In accordance with Annex 10 of the EIAO-TM a final
conclusion is also made concerning the residual landscape and visual impacts
attributable to the proposed scheme. The degree of residual impact is
considered in accordance with the Residual Impact Significance Threshold Matrix
in Table 11.4.4 below.
Table 11.4.4 Residual impact

11.5 Landscape Baseline, Impact Assessment and Mitigation
11.5.1 Landscape Baseline
The
baseline review of the existing landscape establishes the broad
characteristics, identifies LRs, and then
provides a characterisation and evaluation of the identified LCAs. Figures 11.2a
to 11.2e map the existing LRs found within
the 500m assessment area located within the HKSAR. The photographs showing the
existing LRs are presented as Figures 11.2f to 11.2w.
11.5.1.1 Existing Landscape Context
The
original fishponds which once covered the site have largely been filled in and
the LMC Loop is now a combination of reedbed and grassland. The reedbeds are
largely areas of former fishponds or agricultural lands which have become
disused with time and colonised by natural plant species. The reedbed is dominated by herbaceous
vegetation such as Phragmites karka
and Phragmites australis and the
grassland is covered by Neyraudia
reynaudiana, Panicum maximum and climbers.
It is important where possible that the reedbed be retained and enhanced
from both an ecological and landscape perspective. Clusters of
self-seeded trees such as Acacia confusa,
Bombax ceiba, Leucaena leucocephala, Macaranga tanarius and Melia azedarach are found on the LMC
Loop. These tree clusters are located at the
periphery of the Loop and alongside the existing channel maintenance access. Approximately 2,500 nos. existing trees are
located within the Loop with 90% of them being Leucaena
leucocephala.
The
western portion of the assessment area at Lok Ma Chau Boundary Control
Point (LMC BCP) and MTR LMC Station is characterised by infrastructure,
compensatory wetland, and roadside tree planting surrounding the cross-boundary facilities. This developed character extends south to the vehicular
waiting areas for the boundary crossing and open container
storage at San Tin. The roadside tree planting is dominated by a combination of
native and amenity species including Casuarina equisetifolia, Cassia siamea, Cinnamomum
camphora, Ficus microcarpa, Hibiscus tiliaceus, Melaleuca quinquenervia and Spathodea
campanulata etc. Existing trees are located within and
surrounding the MTR LMC Station and LMC BCP, planted alongside the water channel and at
the periphery of the LMC cross-boundary
vehicular waiting areas, in fishpond
areas located to the east, south and west of these cross-boundary facilities. The southern portion of the
assessment area comprises of the vegetated ridges of the LMC and Tai Shek Mo
which have an elevation lower than +120mPD and a series of spurs and knolls
extending from Sandy Ridge to Lo Wu to the east and Ki Lun Shan to the south.
The lower slopes of these upland areas are characterised by mixed woodland
dominated by trees planted for reforestation, landscape enhancement or fruit
production purposes and include species such as Acacia confusa, Casuarina equisetifolia, Celtis sinensis, Clausena
lansium, Cinnamomum camphora, Citrus maxima, Dimocarpus longan, Litchi
chinensis, Lophostemon confertus, Macaranga tanarius and Melia azedarach. At more elevated levels
the hillside woodland vegetation gives way to shrubland and eventually coarse
grassland near the summits along the ridgeline.
A number
of scattered village settlements including Ha Wan Tsuen, Ha Wan Fishermen Village, LMC Tsuen, Tai Law Hau, Ping Hang, Ma Tso Lung and Tse Koo Hang are located within the
assessment area with their associated fishponds and agricultural fields to the
south of the LMC Loop alongside Ha Wan Tsuen Road and existing Boundary Patrol
Road. The village settlements of San Tin and Chau Tau
with their associated extensive open yards for container storage and open car parks are located along sides of LMC Road in close proximity to the LMC Cross-boundary
facilities and the Spur Line. Areas of tree planting, largely for fruit
production, are located at the periphery of villages and on fishpond bunds with
species such as Clausena lansium,
Dimocarpus longan, Litchi chinensis and
Citrus maxima and roadside trees and plantingincluding Casuarina equisetifolia, Lophostemon confertus and Melaleuca leucadendron. A number of
mature trees are located within the fishpond areas to the west of Ha Wan Tsuen
and along Ha Wan Tsuen Road. In particular, a group of mature specimen Ficus macrocarpa and Cinnamomum camphora are located within
the public square at the entrance of Ha Wan Tsuen. Other mature specimens are
also found within LMC Tsuen, Chau Tau and Pun Uk Tsuen, and include species
such as Ficus macrocarpa, Celtis sinensis
and Cinnamomum camphora. In
addition, some mature roadside trees, including species such as Lophostemon confertus and Melaleuca leucadendron, are found along
LMC Road and Boundary Patrol Road adjacent to Ha Wan Tsuen. These specimens are
significant/important trees having a DBH of over 1m and have a relative high amenity value in the
local landscape context. These mature specimen will be further investigate
at detailed design stage according to the criteria of the Registration of Old and Valuable Trees listed in ETWB TCW No. 29/2004. The secondary woodland to the east and south
of Chau Tau and Pun Uk Tsuen are fung
shui woods according to the findings of the ecology survey. The mature
specimen trees within the villages, secondary woodland adjacent to villages and
at the lower slopes of LMC and Tai Shek Mo ridges form a locally important
landscape resource and major landscape features within the rural landscape
context. Existing trees a combination of fruit
trees, exotic tree species along drainage channel and native species on the
uphill, are found within and area surrounding the villages.
An area
of remnant fishponds located to the south of the abandoned meander of the
Shenzhen River with their characteristic rectilinear shapes are considered to
be a regionally significant landscape resource and a distinctive feature within
the assessment area. The main vegetation within this area is reed species
interspersed with some fruit trees and self-seeded species such as Leucaena leucocephala, Macaranga tanarius
and Hibiscus tiliaceus. Hoo Hok Wai
is an area covered by extensive fishponds located to the east of the abandoned meander of the Shenzhen River and to the north of Ma Tso Lung, it comprises of both active fishponds
and wetland which is self-generated from abandoned fishponds.
To the
north of the Loop, the channelized Shenzhen River has been widened or modified
in phases since the 1990s to improve the drainage and rectify the flooding
problems on the coastal plain and lowland areas in the Northwest New Territories (NWNT). This landscape feature is characterised by its engineered
nature due to the straightening of the river coarse, modification of the river
banks and their lining with concrete; and the associated access and maintenance
roads. An area of tree planting, largely
consisting of Hibiscus tiliaceus is located on the southern side of the access road.
The area
to the north of the Shenzhen River has two distinct landscape characters. The
first to the northeast is dominated by high-rise residential developments which
extend in a grid-like form to the channelized banks of the Shenzhen River. The
second character is that of the facilities associated with the Shenzhen
Huanggang, the counterpart to the LMC crossing, with its road development and
extensive apron areas for the processing of cross boundary
traffic. To the west the crossing is flanked by a small parcel of high-rise
residential development designed on spiral layout. The main concentrations of
vegetation include amenity tree and shrub planting lining the riverfront
adjacent to the residential area in the eastern portion and a landscape buffer
from tree and shrub planting adjacent to the hard standing and major
infrastructure development associated with the boundary
crossing.
11.5.1.2 Landscape Resources
Important
determinants of the landscape character within the assessment boundary within
the HKSAR include the key LRs such as the cross boundary
infrastructure and facilities, village settlements, mixed woodlands, tree
planting, roadside trees, shrubland, grassland, agricultural fields, fishponds,
natural stream courses, engineered water channels, marsh, developed areas and
open storage yards. Figures 11.2a to 11.2e map the LRs
within the assessment area and Figures 11.2f to 11.2w provide
photographs of each LR. A broad brush group tree survey is contained in Appendix 11-1 providing a broad picture
of existing trees and their distribution within the assessment area. Detailed
descriptions of these LRs are provided in the following section and summarised
in Table 11.5.2.
Broad brush group
tree survey in Appendix 11-1 covered
the following areas within the 500m LVIA Study Area and summarised in Table 11.5.1. The exact number and the
recommended treatment of the existing trees within the project boundary are
subject to separate tree survey at detailed design stage of the project.

LR1 Cross-boundary Infrastructure and Facilities
The Cross-border
Infrastructure and Facilitates include the boundary crossing infrastructures at
LMC and Huanggang and their other associated buildings such as MTR LMC Station
and public transport terminus, the bus / mini-bus terminal, immigration office
building and infrastructure, and railway and highways,
car parking and vehicular queuing up area for boundary crossing. These
facilities are characterised by the buildings and extensive concrete paved
areas and are heavily modified by human activity and so overall are considered
to have a low sensitivity.
LR1.1 Cross-boundary Infrastructure and Facilities (MTR LMC Station)
This LR is
dominated by infrastructure buildings and the associated PTI. The periphery of
the cross-boundary facilities and internal access roads are lined by tree
planting. The majority of the trees were planted for screening and amenity
purposes and comprise of common species found in Hong Kong. Approximately 450
nos. of trees are found within the LR including species such as Casuarina equisetifolia, Cassia siamea, Cinnamomum camphora, Ficus microcarpa, Hibiscus tiliaceus, Leucaena leucocephala, Macaranga tanarius, Melaleuca quinquenervia and Spathodea campanulata. Over half of the trees are exotic species and there is little shrub
planting within the area. The condition
and amenity value of the existing trees within this area are fair, the trees
are relatively mature (150-200mmDBH) and contribute to the local infrastructure
landscape. This LR is composed of manmade features, does not have a high
amenity value to the local rural and riverside context, and has a high
tolerance to accommodate change, so is considered to have a low sensitivity.
LR1.2 Cross-boundary Infrastructure and Facilities (Lok Ma Chau
Vehicular Areas)
This LR is
composed of vehicular cross-boundary facilities and vehicular waiting areas. It is
largely hard paved with trees along its periphery and the Lung Hau Road
planting areas. The area includes some 760 nos. of trees consisting of common
roadside / riverside species including Hibiscus tiliaceus, Casuarina equisetifolia and Ficus
microcarpa. There are also a relatively
large number of the weed tree species Leucaena leucocephala within the planting area. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively mature
(150-300mmDBH) and contribute to the local infrastructure landscape. Given the
function of this LR, its relative low amenity value; low importance to the
local context and its high tolerance to accommodate change, it is considered to
have a low sensitivity.
LR1.3 Cross-boundary Infrastructure and Facilities (Lok Ma Chau Bus
Terminal)
Similar to the
above LRs, this LR is largely hard paved and has approximately 50 nos. of trees
located at the periphery with the main species being Casuarina equisetifolia. The condition and
amenity value of the existing trees within this area are fair, the trees are
relatively mature (150-200mmDBH) and contribute to the local infrastructure
landscape. Given the function of this LR, its relatively low amenity value; low
importance to the local context and high tolerance to accommodate change, it is
considered to have a low sensitivity.
LR2 Village Settlement
The main
concentration of village settlements within the assessment area include Tung
Chan Wai at San Tin, Ha Wan Tsuen, Ha Wan Fishermen Village, Pun Uk Tsuen and
Chau Tau Tsuen along LMC Road, LMC Tsuen, Tai Law Hau and Ping Hang located
alongside the existing Boundary Patrol Road.
Some of these village settlements including Ha Wan Tsuen, LMC, Tai Law Hau and Ping Hang are located to the south across the meander and
fishponds close to the LMC Loop. Other village settlements are scattered along
the road corridors including LMC Road, Ha Wan Tsuen Road and the existing
Boundary Patrol Road, and the adjacent lowland rural landscape. These areas are
characterized by extensive groups of 3-storey village houses which form the
settlement pattern within the lowland landscape. The existing building forms
include a combination of traditional dwellings although the majority of the
buildings consist of newer type developments connected by narrow lanes and
footpaths.
LR2.1 Ha Wan Tsuen Village Settlement
This LR is mainly composed of scattered temporary squatters alongside of fishpond. Two small scale playgrounds for the use of villagers are located to the north and to the south of the village. No ancestral hall or temple in the village. The area contains some 200 nos. trees consisting of common roadside species, fruit trees planted for cultivation purposes or self-seeded species spreading from adjacent wooded areas. Mature specimen trees are also found along Boundary Patrol Road, one Celtis sinensis, and Cinnamomum camphora, Ficus elastic, Ficus virens and Ficus microcarpa at the entrance of Ha Wan Tsuen. Other tree species include Casuarina equisetifolia, Ficus variegata, Celtis sinensis, Bombax ceiba, Mangifera indica, Artocarpus heterophyllus, Cinnamomum camphora, Ficus microcarpa, Hibiscus tiliaceus, Lagerstroemia speciosa, Leucaena leucocephala, Macaranga tanarius, Syzygium jambos, Melaleuca quinquenervia, Melia azedarach, Psidium guajava, Averrhoa carambola and Dimocarpus longan. The condition and amenity value of the existing trees within this area are fair to good, the trees are relatively mature (300 to 500mmDBH) and contribute to the local rural landscape. A few mature specimen have a size over 800mm. Given a combination of the rural setting of this LR, its medium amenity value to the local context; its medium maturity and relatively low regional importance due to its coverage and its medium tolerance to accommodate change; it is considered to have a medium sensitivity.
LR2.2 Lok Ma Chau Road Village Settlement
This LR is
composed of a small number of modern styled three-storey village houses and
temporary squatters located alongside Lok Ma Chau Road. Approximately 20 nos.
trees have been planted in the private gardens or adjacent to the fishponds.
The main species are common to Hong Kong and include Dimocarpus longan, Litchi chinensis, Macaranga tanarius and Pinus massoniana etc. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively young (300 to 500mmDBH) and contribute to
the local rural landscape. Given a
combination of the relatively small extent of this LR, its limited contribution
to the amenity value and to the local context of Lok Ma Chau Road amenity
value, its low maturity and its relatively low importance due to its limited
coverage and have been fragmented by Spur Line railway works and LMC Road works
and its high tolerance to accommodate change, it is considered to have a low
sensitivity.
LR2.3 Lok Ma Chau Tsuen Village Settlement
This LR is composed of rows of village
houses with traditional style of village establishment. Village houses are
largely modern styled two-storey residential houses with a number of historic
old village houses built with green bricks and temporary squatters. Extensive
fishponds and active agriculture fields are located to the north of the
village. The trees are largely self-seeded colonising the area from adjacent
wooded areas or planted for agriculture purposes. Approximately 60 nos. trees
are found along the southern edge of the village settlement adjacent to the
wooded areas with the main species being Dimocarpus longan, Litchi
chinensis, Macaranga tanarius, Melia azedarach and Ficus microcarpa. The
condition and amenity value of the existing trees within this area are fair to
good, the trees are relatively mature (300 to 800mmDBH) and contribute to the
local rural landscape. Given a combination of the maturity of this LR, its medium
amenity value and contribution to the landscape context of Lok Ma Chau and its
medium tolerance to accommodate change it is considered to have a medium
sensitivity.
LR2.4 Ha Wan Fishermen Village Settlement
This LR is located
at the lower slopes of the Lok Ma Chau Ridge and is composed of a small number
of temporary squatters orientated in a grid and enclosed pattern. It is
established by Ha Wan Tsuen villagers when Ha Wan Tsuen has no room for further
expansion due to increase of population. The existing approximately 20 nos. trees are located along the eastern edge of the
village settlement adjacent to the wooded areas. These trees are largely
self-seeded colonising the area from the adjacent wooded areas or planted for
agricultural purposes. The main species include Dimocarpus longan, Litchi chinensis, Macaranga tanarius, Melia azedarach and Ficus microcarpa. The condition and amenity value of the existing trees within this area
are fair, the trees are relatively young (200 to 500mmDBH) and contribute to the local rural landscape. Given a combination of the small
extent of this LR, its limited contribution to the amenity value and local
rural context of Lok Ma Chau, its low maturity and its high tolerance to
accommodate change, it is considered to have a low sensitivity.
LR2.5 Chau Tau and Pun Uk Tsuen Village Settlement
This LR is set back from Lok Ma Chau Road, and is formed by rows of village houses. Most of the buildings now are modern styled two-storey residential buildings. Quite a number of historic and traditional old village houses and halls are found in the village. The approximately 30 nos. existing trees are located alongside the access road from Lok Ma Chau and along the access road southern edge of this village settlement adjacent to the wooded areas. These trees are largely self-seed colonising the site from the adjacent wooded areas or planted for amenity purposes. The main tree species include Celtis sinensis, Cinnamomum camphora, Macaranga tanarius, Dimocarpus longan Archontophoenix alexandrae Casuarina equisetifolia, Cleistocalyx operculata, Lophostemon confertus and Eucalyptus tereticornis. The condition and amenity value of the existing trees within this area are fair to good, the trees are relatively mature (300 to 800mmDBH) and contribute to the local rural landscape. Given a combination of the relatively small extent of this LR, its maturity and medium contribution to the amenity value and to the local context Lok Ma Chau; and its medium tolerance to accommodate change, it is considered to have a medium sensitivity.
LR2.6 San Tin Village Settlement
Within the
assessment area San Tin is largely occupied by open container storage,
workshops and carparks; and the village settlements bisected by the alignment
of the Fanling Highway. Village houses are
scattered in location and in form of modern
styled three-storey residential
buildings. Quite a number of historic and traditional old village houses and
halls are found in the village. Given the
domination of industrial uses and the density of development there are few
trees, approximately 40 trees nos., within the village. The main species
include Casuarina
equisetifolia, Cinnamomum camphora, Bombax ceiba, Cassia siamea and
Eucalyptus tereticornis etc. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively mature (200 to 500mmDBH) and contribute to
the local rural landscape. Given
factors such as the disturbed rural setting surrounding this LR, its low maturity
and relatively small contribution to the amenity value of the local context;
and its high tolerance to accommodate change,
it is considered to have a low sensitivity.
LR2.7 Tai Law Hau Village Settlement
This LR is
composed of a few temporary squatters only adjacent to abandoned agriculture
fields. Given the enclosed nature of the topography, only a few, approximately
10 nos. trees, including Bombax ceiba, Macaranga tanarius and Melia
azedarach are found at the
southern edge of the settlement. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively young (100 to 300mmDBH) and contribute to
the local rural landscape. Given a
combination of the small extent of this LR, its low maturity, its limited contribution
to the local amenity value and to the local context of Lok Ma Chau; and its
high tolerance to accommodate change, it is considered to have a low
sensitivity.
LR2.8 Ping Hang Village Settlement
Similar to LR 2.7,
this LR is composed of only two numbers of temporary squatters adjacent to
abandoned agriculture fields. The
condition and amenity value of the existing trees within this area are fair,
the trees are relatively young (100 to 300mmDBH) and contribute to the local rural landscape. Given the size of the area and its enclosed topography, only a few, approximately 10 nos., of Macaranga tanarius and Melia
azedarach are located along the
southern edge of the settlement. Given a combination of the limited extent of
this LR, its low maturity, its small contribution to the amenity value and
local context of Ma Tso Lung; and its high tolerance to accommodate change, it
is considered to have a low sensitivity.
LR2.9 Tse Koo Hang Village Settlement
Similar to LRs 2.7
and 2.8, this LR is composed of ten numbers of temporary squatters adjacent to
abandoned agriculture fields which are largely abandoned and was originally
utilised for cultivation and framing purpose. Given its size and enclosed
topography, only a few, approximately
60 nos. trees including Bombax ceiba, Macaranga tanarius and Melia
azedarach are found at the edge of
the settlement. The condition and amenity value of the existing trees
within this area are fair, the trees are relatively young (300 to 500mmDBH) and contribute to
the local rural landscape. Given the
small size of this LR, its low maturity, its
low contribution to the amenity value and local context Ma Tso Lung; and
its high tolerance to accommodate change, it is considered to have a low sensitivity.
LR2.10 Ma Tso Lung Village Settlement
This LR is
composed of an intermediate number of three storey village houses and temporary
squatters adjacent to agriculture fields. The houses and structures are located
on a series of terraced platforms extending to the mid-slopes of Crest Hill.
Some 245 nos. trees have been planted along Ma Tso Lung Road, in garden areas
for amenity or cultivation proposes; and areas of self-seeded trees adjacent to
nearby wooded areas. The main species found within this LR include Celtis sinensis, Cinnamomum camphora, Microcos paniculata, Dimocarpus longan, Litchi chinensis, Macaranga tanarius, Mangifera indica and Melia azedarach. The condition and
amenity value of the existing trees within this area are fair, the trees are
relatively mature (300 to 800mmDBH) and
contribute to the local rural landscape. Given a combination of factors such as the density of the
village development; the quality of the setting; its medium maturity and
contribution to the amenity value and local context Ma Tso; and its medium
tolerance to accommodate change, it is considered to have a medium sensitivity.
LR3 Mixed Woodland
The majority of
the woodlands within the assessment area are mixed woodland located away from
the LMC Loop. This includes mixed woodlands
located adjacent to the Ha Wan Tsuen, Chau Tau, Pun Uk Tsuen, Ma Tso Lung and
along Lok Ma Chau Road.. The dominant species within these areas are native
tree and shrub species such as Aquilaria
sinensis (protected
under Cap. 586), Aporusa dioica, Celtis sinensis, Cinnamomum camphora, Cratoxylum
cochinchinense, Mallotus paniculatus, Schefflera heptaphylla, Schima superba,
Psychotria asiatica and Uvaria macrophylla. Due to the unique
nature of the woodlands which form this resource overall they are thought to be
locally significant and hence their sensitivity is considered to be high.
LR3.1 Ha Wan Tsuen Road Mixed Woodland
This LR is a
vegetated slope located to the south of Ha Wan Tsuen. It is composed of
woodland trees and scrubland surrounding abandoned fishponds with some 506 nos.
trees including species such as Celtis sinensis, Cinnamomum camphora, Ficus microcarpa, Lophostemon
confertus, Macaranga tanarius, Melia azedarach, Psidium guajava and Sapium
sebiferum. The condition and amenity value of the existing trees within this area
are fair to poor, the trees are relatively young (300 to 600mmDBH) and contribute to the local rural landscape. The woodland area
is traversed by Ha Wan Tsuen Road
and Lung Hau Road and so is fragmented. Given
the contribution of this LR to the amenity and landscape context of Ha Wan
Tsuen village and despite its small size and the area being disturbed by the
existing cross-boundary facilities and infrastructure works it is considered to
have a high amenity value; to be relatively locally important and is less
tolerant to change, and so is considered to have a high sensitivity.
LR3.2 Lok Ma Chau Road Mixed Woodland
This LR is formed
by a vegetated slope extending west down from the Lok Ma Chau Ridge to Lok Ma Chau
Road. It is composed of woodland trees and shrubland; and is important in its
contribution to the landscape backdrop for Lok Ma Chau Tsuen, Ha Wan Fishermen
Village, Chau Tau and Pun Uk Tsuen. The woodland comprises of some 1,181 nos.
trees including species such as Celtis sinensis, Cinnamomum camphora, Cleistocalyx operculata, Delonix
regia, Ficus microcarpa, Macaranga tanarius, Microcos paniculata, Leucaena
leucocephala and Lophostemon confertus. The condition and
amenity value of the existing trees within this area are fair to good, the
trees are relatively mature (300 to 800mmDBH) and contribute to the local rural landscape. The baseline for the ecological impact assessment also
identified specimens of a
protected tree species Aquilaria sinensis
(protected under Cap. 586) with a sapling at the fringe of the secondary
woodland adjacent to the access road to LMC Tsuen; and a small number of
seedlings and a mature specimen recorded within the secondary woodland close to
Pun Uk Tsuen. Given a combination of factors such as its high amenity value;
the contribution to the landscape context and amenity of the local area; its
maturity and low tolerance to change this LR is considered to have a high
sensitivity.
LR3.3 San Tin Mixed Woodland
This LR is composed
of small vegetated remnant slopes at San Tin separated by the alignment and
structures associated with the San Tin and Fanling Highways; Castle Peak Road
and Kwu Tung Road. Although these areas are piecemeal in their distribution
they contain a number of mature tree specimens and contain some 710 nos. trees
comprising of species such as Acacia confusa, Bombax ceiba, Cassia siamea, Cinnamomum camphora, Ficus
benjamina, Ficus microcarpa, Ficus virens, Macaranga tanarius, Melia azedarach and Roystonea
regia. The condition
and amenity value of the existing trees within this area are fair, the trees
are relatively mature (300 to 800mmDBH) and
contribute to the local rural landscape. The trees have been planted as part of the
mitigation for the original highway works.
The value of this LR is to the landscape setting of Ha Wan Tsuen village
which is situated in a village disturbed by a combination of existing
development including the LMC infrastructure cross-boundary facilities and
infrastructure works located to the west. Despite its relatively small size the
LR has a high amenity value to the local context and is relatively locally
important; is less tolerant to accommodate change, and so is considered to have
a high sensitivity.
LR3.4 Ma Tso Lung Mixed Woodland
This LR is a
vegetated slope located to the west of Shun Yee Shun Tsuen at Ma Tso Lung. It
was fragmented by infrastructure developments such as the Boundary Patrol Road,
Ma Tso Lung and recently completed drainage improvement works. It is composed
of some 480 nos. woodland trees and areas of scrubland with the main species
being Bombax
ceiba, Celtis sinensis, Cinnamomum camphora, Cratoxylum ligustrinum, Macaranga
tanarius, Mallotus paniculatus and Melia azedarach. The condition and amenity
value of the existing trees within this area are fair, the trees are relatively
mature (300 to 800mmDBH) and
contribute to the local rural landscape. Given the contribution of this LR to the landscape setting and backdrop to Ma Tso Lung; its high
amenity value; importance to the local context and local importance; it’s low
tolerance to change it is considered to have a high sensitivity.
LR4
Roadside Planting
Roadside planting
are typically associated with the major infrastructural developments including
the boundary crossing at LMC, San Sham Road and the LMC Spur Line, Lung Hau
Road, Lok Ma Chau Road, Ha Wan Tsuen Road, Ma Tso Lung Road, Fanling and San
Tin Highways. The main value of this LR is in its contribution to the landscape
as tree groups rather than as individual trees. The reason for this is that
many of the trees are fast growing non-native species which were commonly
planted as mitigation for infrastructure works including road schemes,
reforestation, and landscape amenity and /or fruit production purposes. The
trees within these areas are normally planted close together and in rows to
create an instant effect and as a result many of them are growing with a
leaning or unbalanced form. These areas include species such as Acacia auriculiformis, Acacia confusa,
Albizia lebbek , Lophostemon confertus, Casuarina equisetifolia, Clausena
lansium, Dimocarpus longan, Litchi chinensis, Melaleuca quinquenervia, and Syzygium jambos. Some of these areas
along Lung Hau Road and Lok Ma Chau Road are also planting with common roadside
shrub species including Calliandra
haematocephala, Duranta repens and Hibiscus rosa-sinensis etc. It is
considered that this resource has less ecological and landscape value than the
mixed woodland and is reasonably tolerate to change, hence it is considered to
have a medium sensitivity.
LR4.1 Roadside Planting along Lung Hau Road
The planting
established along Lung Hau Road was designed as part of the landscape and
visual mitigation for the MTR Sheung Shui to LMC Spur Line. The planting
includes some 340 nos. trees and areas of shrubs comprising of species commonly
used as part of large infrastructure projects including Casuarina equisetifolia, Ficus
benjamina, Lophostemon confertus, Melaleuca quinquenervia and Melia
azedarach. Common roadside
shrub species are planted including
Calliandra haematocephala, Duranta repens and Hibiscus rosa-sinensis etc. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively young (150 to 300mm DBH) and contribute
to the local infrastructure landscape. The
trees which form this LR are
relatively young being planted some 10 years ago. Given that this area of trees
was planted as part of the infrastructure development to mitigate its impacts,
it is important to the local landscape context; has a medium amenity value and
tolerance to accommodate change; and so are considered to have a medium
sensitivity.
LR4.2 Roadside Planting along Fanling and San Tin Highways
The planting
within this LR includes some 1,250 nos. relatively mature trees and comprises
of typical roadside amenity and exotic species such as Acacia confusa, Bombax ceiba,
Cassia siamea, Casuarina equisetifolia, Cinnamomum camphora, Eucalyptus
citriodora, Eucalyptus tereticornis, Ficus benjamina, Ficus virens, Macaranga
tanarius, Melia azedarach and Roystonea regia. The condition and
amenity value of the existing trees within this area are fair, the trees are
relatively young (150 to 250mm DBH) and
contribute to the local infrastructure landscape. In addition there are numerous specimens of
the aggressive weed tree species Leucaena leucocephala. These planting areas are
generally covered by grass. Given a combination of factors such as the importance
of the tree planting to softening the form of the Fanling and San Tin
Highways and
its associated structures; its contribution to the to the local landscape
context; and that the LR has medium
amenity value; is relatively locally important and has a medium tolerance to
change it is considered to have a medium sensitivity.
LR4.3 Roadside Planting along Lok Ma Chau Road
This LR is formed
by typical roadside amenity planting including some 325 nos. trees along the
district road and comprises of commonly utilised species such as Casuarina equisetifolia,
Cinnamomum camphora, Cleistocalyx operculata, Delonix regia, Ficus microcarpa,
Lophostemon confertus, Macaranga tanarius, Mangifera indica and
Melaleuca quinquenervia. Some common roadside shrub species are
planted including Calliandra
haematocephala, Duranta repens and Hibiscus rosa-sinensis etc. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively mature (200 to 800mm DBH) and contribute
to the local infrastructure landscape. These resources are relatively mature particularly
some of the roadside trees and the trees located within island planters. Given
a combination of the contribution of this LR within the local context, the
softening of the form of the road and its associated structures; its medium amenity value; local importance
and tolerance to accommodate change this LR is considered to have a medium
sensitivity.
LR4.4 Roadside Planting along Ha Wan Tsuen Road
This roadside
landscape comprises of some 25 nos. mature tree alongside of Ha Wan Tsuen such
as Albizia lebbek, Ficus microcarpa, and
Melaleuca quinquenervia. They are originally planted over 20 years ago when the road being
constructed. The condition and amenity value of the existing trees within this
area are fair to poor, the trees are relatively mature (600 to 800mm DBH) and contribute
to the local roadside landscape. However
decay, insect and fungal infestation and structural defects are found in these
roadside trees due to its age and naturally succession. No shrub or groundcover
found in these planting areas. Given a
combination of the contribution of this LR within the local context, the
softening of the form of the road and its associated structures; its maturity
and medium amenity value; local importance and tolerance to accommodate change
this LR is considered to have a medium sensitivity.
LR4.5 Roadside Planting along Ma Tso Lung Road
This roadside
landscape comprises of some 375 nos. trees located adjacent to village houses
and composed of largely amenity and fruit trees such as Archontophoenix alexandrae, Bombax
ceiba, Celtis sinensis, Cinnamomum camphora, Cratoxylum ligustrinum, Macaranga
tanarius, Mallotus paniculatus, Melia azedarach, Pinus massoniana and
Plumeria rubra var. actifolia. The condition and amenity value of the
existing trees within this area are fair, the trees are relatively young (100 to 300mm DBH) and contribute
to the local infrastructure landscape. Common shrub species including Morus alba Linn., Carmona microphylla,
Ligustrum sinense etc. are found along the
road. Despite the
relatively random distribution of the trees within this LR they contribute to
the local rural context with a medium amenity value, have a medium sensitivity
to change and so are considered to have a medium sensitivity.
LR4A Trees on the Loop
This LR comprises
of some 2,500 nos. trees including a significant number of the aggressive,
self-seeded weed tree species Leucaena leucocephala, over 90% of total number
of trees, with lesser numbers of self-seeded exotic, naturalized and
native trees spreading from adjacent woodland and new tree planting along
Boundary Patrol Road newly constructed. The trees are generally found in
clusters with many trees shaped by the exposure of the site. Beyond the prevalence of Leucaena
leucocephala the main tree species include Acacia confusa, Bischofia javanica, Bombax
ceiba, Celtis sinensis, Ficus microcarpa, Hibiscus tiliaceus, Macaranga
tanarius and Melia azedarach. Given a combination of the sporadic coverage of the
trees which form this LR, their immature age and relatively small size; their
relatively low value to the landscape character and amenity of the site; this
LR is considered to have a high tolerance to change and a low sensitivity.
LR5 Shrubland
The main area of
shrubland is located within the middle slopes of the hillsides below the ridges
to the south of the LMC Loop and is bounded by extensive mixed woodland at
lower elevations to the north. The other areas of shrubland are located to the north-east
of Ping Hang, and are enclosed by a number of fishponds to the north and
extensive woodland to the south. This resource typically forms a succession
stage of grassland as it becomes colonised by tree and shrub species. A
detailed description of the floristic composition of the shrubland areas is
provided in Chapter 12.
LR5.1 Shrubland at Lok Ma Chau
This area of
shrubland is located on the hill slopes of Lok Ma Chau Ridges to the east of Ha
Wan Fishermen Village and Lok Ma Chau Tsuen, and adjacent to Tai Law Hau and
Ping Hang. The hillside shrubland is interspersed with adjoining hillside LRs
(i.e. grassland, secondary woodland and other shrubland fragments). It is
comprised of common shrub species including Rhodomyrtus
tomentosa, Clerodendrum cyrtophyllum, Callicarpa kochiana, Rhus chinensis
and Rhaphiolepis indica and some
isolated tree species including Cratoxylum
cochinchinense and Sapium discolor. The area also composed of some 306 self-seeded
and fruit trees such as Averrhoa
carambola, Celtis sinensis, Dimocarpus longan, Litchi chinensis, Macaranga
tanarius, Melia azedarach and Microcos nervosa, etc. which are spreading
from adjacent woodlands or cultivated by villagers, they are mainly located
alongsides of existing Boundary Patrol Road, adjacent to villages and at the
lower slopes of Lok Ma Chau Ridges. The
main importance of this LR is in combination with the other hillside LRs
creating a tapestry of landscape and forming the backdrop to views of the
landscape from lower levels. This resource has a medium significance within
this landscape context, a medium tolerance to change and hence is considered to
have a medium sensitivity.
LR5.2 Shrubland at Ma Tso Lung
The shrubland forming
this LR is located on the hill slopes to the north and east of Ma Tso Lung, to
the south of Tse Koo Hang and area surrounding the HKPF Lok Ma Chau Operation
Base. This shrubland forms the transitional landscape between the wooded lower
hill slopes and the grassland at the summit of the hills. The species
composition and vegetational structure are similar to that of the Lok Ma Chau
area. The area composed of some 305 self-seeded and fruit trees such as Celtis sinensis, Clausena lansium,
Dimocarpus longan, Litchi chinensis, Macaranga tanarius, Melia azedarach and
Microcos nervosa, etc. which are spreading from adjacent woodlands or
cultivated by villagers, they are located along sides of existing Boundary
Patrol Road, adjacent to villages and at the lower slopes of Tai Shek Mo.
Similarly the main importance of this LR is in combination with the other
hillside LRs and forming part of the backdrop to views of the landscape from
lower levels. This resource has a medium significance within this landscape context,
medium tolerance to change and hence is considered to have a medium
sensitivity.
LR6 Grassland
The assessment
area contains an extensive coverage of grassland, which is the dominant
landscape resource on top of the hills and mountains located to the north of
Fung Kong Shan and to the west of Tai Shek Mo in the southern part of the
assessment area. The other extensive area of grassland is located within the
LMC Loop which is surrounded by a natural water course to the east, south and
west. Originally, the area forming the LMC Loop comprised of fishponds however
these were filled in to form grassland. The upland grassland areas form part of
the green backdrop to many of the views available in locations within the
assessment area. Common grass species include Arundinella spp., Eulalia spp. and Ischaemum spp. Overall these areas are considered to have a low
sensitivity.
LR6.1 Grassland on the Loop
The LMC Loop is
largely covered by extensive grassland that has established due to the filling
in of the fish ponds and through natural succession. This LR is dominated by
grassy vegetation (such as Brachiaria
mutica, Panicum maximum and Imperata koenigii) and other herbs and
creepers (including Bidens alba, Mimosa pudica, Sesbania spp., Eupatorium
catarium, Ipomoea cairica and Mikania micrantha). The grassland is interspersed with other LRs
including clumps of tree planting and marshland. This resource has a low
significance within this landscape context and high tolerant to change and
hence is considered to have a low sensitivity.
LR6.2 Grassland at San Tin
The grassland
areas of San Tin include a number of small areas which have established on the
upland areas and form part of the fire-maintained hillside grassland on the
hill slopes of Ki Lun Shan. It is dominated by common species such as the fern Dicranopteris pedata and grasses such as
Miscanthus sinensis, Imperata koenigii and Neyraudia reynaudiana. Shrubs / small
trees (such as Rhus hypoleuca, Rhus succedanea, Rhodomyrtus tomentosa, Breynia
fruticosa and Desmodium heterocarpon)
and trees (such as Cratoxylum
cochinchinense, Aporusa dioica
and Pinus massoniana) are also
present. It is also composed of some 50 trees
including species Celtis sinensis,
Cinnamomum camphora and Macaranga tanarius etc., they are self-seeded from
adjacent woodland. This LR has a low significance within this
landscape context and high tolerant to change and hence is considered to have a
low sensitivity.
LR6.3
Grassland at Lok Ma Chau and LR6.4 Grassland at Ma Tso Lung
These two areas
form a similar LR to the fire-maintained hillside grassland LR6.2 Grassland at
San Tin and have a similar species composition.
LR6.3 is located on the hill slopes to the east of Ha Wan Fisherman
Village and Lok Mau Chau Tsuen; and LR6.4 an extensive area to the south of Ma
Tso Lung and a smaller area to the east.
LR6.3 and LR6.4 also compose of 310 and 310 self-seeded trees
respectively spreading from adjacent to woodland such as Celtis sinensis, Cinnamomum camphora,
Melia azedarach and Macaranga tanarius etc. These two areas of grassland have a low
significance within this landscape context and high tolerant to change and
hence are considered to have a low sensitivity.
LR7 Agricultural Fields
The agricultural
fields within the assessment area are associated with the village settlements
at Tse Koo Hang and Chau Tau Tsuen. The common plant species in these areas
include Ipomoea cairica, Brachiaria
mutica, Conyza bonariensis, Bidens alba, Amaranthus viridis, Ipomoea triloba,
Emilia sonchifolia, Youngia japonica, Mikania micrantha, Mimosa pudica,
Polygonum chinense, Scoparia dulcis, Solanum nigrum, Panicum maximum and Cynodon dactylon. The agricultural
fields are important to the landscape setting of local villages forming
remnants of the historical landscape which was once common in the area and
contribute to the scale and texture of the landscape. Therefore the overall
ability of this resource to accommodate change is considered to be medium and
it is considered to have a medium sensitivity.
LR7.1 Pun Uk Tsuen Agricultural Fields
This small area of
agricultural fields to the south west of the village settlement is
characterised by a fine textured field pattern cultivated for vegetables and
forms an important part of the historical / cultural landscape of the
area. Some 160 trees largerly fruit
trees such as Dimocarpus longan and
Mangifera indica, are found within or at the edge the agricultural fields.
This area is also relatively less important to the present day landscape
setting and so the ability of this resource to accommodate change is considered
to be medium and hence has a medium sensitivity.
LR7.2 Lok Ma Chau Tsuen Agricultural Fields
This LR, located
to the north west of Lok Ma Chau Tsuen, is formed by cultivated agricultural
fields and forms an important part of the historical / cultural landscape. Some
10 trees largely fruit trees such as Dimocarpus
longan and Litchi chinensis, are found within or at the edge the
agricultural fields. Owing to its location and proximity to the village this
area is relatively less important to the landscape setting and so the ability
of this resource to accommodate change is considered to be medium and hence has
a medium sensitivity.
LR7.3 Lok Ma Chau Agricultural Fields
This LR comprises
of a small area of wet agricultural land. As with LR7.2 described above the
agricultural fields form an important element within the landscape. The main
species within the wet agricultural land include common herbaceous vegetation
such as Alocasia odora, Colocasia esculenta, Ipomoea aquatica, Ipomoea batatas and isolated shrubs (such as Lantana camara). Some 25 trees largely fruit trees such as Averrhoa carambola, Litchi chinensis and Syzygium jambos are found within or at the
edge the agricultural fields. This area is relatively less important to the
landscape setting and so the ability of this resource to accommodate change is
considered to be medium and hence has a medium sensitivity.
LR7.4 Ma Tso Lung Agricultural Fields
The agricultural
fields to the east of the village of Ma Tso Lung are located on the valley
floor between the lower hill slopes of Ma Tso Lung and Tai Shek Mo. Some 210
trees largely fruit trees such as Annona
squamosa , Artocarpus heterophyllus, Averrhoa carambola, Clausena lansium ,
Dimocarpus longan , Litchi chinensis and Mangifera indica are found within
or at the edge the agricultural fields. This area is formed from both active
and abandoned agricultural land, and is relatively important to the landscape
setting of the adjacent village houses. Its ability to accommodate change is
considered to be medium and it has a medium sensitivity.
LR8 Fishponds
The assessment
area contains an extensive coverage of fishponds including areas at LMC, Sam Po
Shue, Ha Wan Tsuen and Hoo Hok Wai. The fishponds extend from the Deep Bay
coastal plain in the west into the lowland rural area along Shenzhen River to
the east at Sam Po Shue and Hoo Hok Wai. These fishponds are characterised by
their rectilinear shapes and are considered to be a regionally significant
landscape resource and a distinctive feature within the assessment area. The
main species composition of these areas includes Brachiaria mutica, Phragmites australis, Panicum maximum and Cynodon dactylon. Overall this resource
is considered to be important to the landscape setting of the assessment area
and is susceptible to small changes and hence is considered to have a medium to
high sensitivity.
LR8.1 Sam Po Shue Fishponds
Located to the south
of the wetland created as mitigation for the LMC Spur Line these fishponds form
part of a more extensive area stretching from San Tin in the east to Mai Po in
the west. The ponds are enclosed by
bunds with tree planting which acts to screen views of the adjacent
infrastructure. Some 275 trees are found adjacent to the edge of MTR LMC
Station and mitigation wetland and alongside of Boundary Patrol Road, they are
mainly exotic species such as Casuarina equisetifolia, Hibiscus tiliaceus and
Melia azedarach etc. This LR is an important landscape feature contributing to
the landscape character and visual amenity of the area. As such and owing to
the openness of the landscape forming the LR it is considered to be highly
susceptible to small changes and so has a high sensitivity.
LR8.2 Ha Wan Tsuen Fishponds
This LR is
enclosed to the north by the engineered slopes of the flood protection works
for the Shenzhen River, to the east by the abandoned meander; south by the
viaduct of the LMC Spur Line and to the west by San Sham Road and the
associated boundary control facilities. Some 259 trees are located on fishpond
bunds, adjacent to the Spur Line and Boundary Patrol Road, they are composed of
both native and exotic species such as Casuarina
equisetifolia, Celtis sinensis, Hibiscus tiliaceus, Macaranga tanarius,
Melaleuca quinquenervia and Melia azedarach etc. Despite its small size and fragmentation this
area of fish ponds is considered to be a less important part of the overall LR
and is less important to the landscape setting of the proposed development. It
is considered to be medium susceptible to change and has a medium
sensitivity.
LR8.3 Lok Ma Chau Road Fishponds
This relatively
small area of remnant fish ponds located to the south of Lung Hau Road and to
the west of Lok Ma Chau Road and forms the setting to the settlement. Some 100 trees lined bunds serve to enclose
the fish ponds and reduce the impact of adjacent developments such as the
viaduct for the LMC Spur Line. Species include Casuarina equisetifolia, Hibiscus tiliaceus, Macaranga tanarius
and Melaleuca quinquenervia etc. Although covering a relatively small
area the fishponds form a less important LR and together with adjacent fishpond
areas contribute to the landscape character of the area. Owing to their size and uniqueness this LR is
considered to be relatively less susceptible to change and so has a medium
sensitivity.
LR8.4 Lok Ma Chau Fishponds
This extensive
area of fishponds forms part of the historical landscape of the area with its
relationship to the abandoned river meander, the agricultural fields and
settlement pattern of villages such as Lok Ma Chau Tsuen, Tai Law Hau and Ping
Hang and the wooded hill slopes which form the backdrop. Located to the south
and southeast of the LMC Loop the fishponds are rectilinear in shape to the
east and west becoming more organically shaped in the central portion.
Generally the bunds which separate the ponds are characterised by a combination
of coarse grassland, specimen trees and small tree clumps. Some 430 trees are
found on wider bunds, they are largely fruit trees cultivated by villagers
including species Artocarpus
heterophyllus, Citrus maxim, Clausena lansium, Dimocarpus longan, Litchi
chinensis, Mangifera indica and Psidium guajava etc. and some self-seeded
trees Macaranga tanarius and Melia
azedarach. Given their contribution to the traditional village landscape of
the area, their relative openness and their overall importance as a LR this
area is considered to be highly susceptible to change and so have a high
sensitivity.
LR8.5 Hoo Hok Wai Fishponds
Forming perhaps
the largest area of fishponds within the assessment area this LR is part of the
transition from the developed landscapes of LMC and the abandoned meander to
the more rural, agricultural landscape of Shun Yee San Tsuen and Liu Pok to the
east. The fishponds of this LR, located in the eastern part of the assessment
area, are interspersed with marshland areas where the water bodies have
succumbed to natural succession. The
earth bunds which separate the ponds are vegetated with a combination of coarse
grassland and small groups and trees and shrubs. Some 379 trees found in the
area are largely self-seeded trees such
as Celtis sinensis, Hibiscus tiliaceus,
Leucaena leucocephala and Melia azedarach etc. .Given its size and location
this LR is considered to be highly susceptible to change and so has high
sensitivity.
LR9
Natural Stream / River Course
Natural watercourse includes LMC Meander (Appendix 12-12, plate 9), its
riparian vegetation and a few overgrown natural streams close to LMC; total area
is 17.18ha.
Common and weedy grassy vegetation (such as Brachiaria
mutica and
Panicum maximum) and
wetland herbs (including Commelina
diffusa, Cyperus
malaccensis and Phragmites australis) predominate. Isolated shrubs and trees
(such as Lantana camara, Ficus hispida, Leucaena
leucocephala and Macaranga
tanarius) are present along the Meander. Many of the small streams in this area are polluted to some extent, often with domestic sewage.
LR9.1
Natural River (To the South of the Loop)
The natural river
course bounding the LMC Loop to the east, south and west, forms an abandoned
meander of the Shenzhen River left behind after river training works in 1990.
The river course is organically shaped with a natural, earth river bank and
associated vegetation which includes a combination of wetland herbs, grassland
and shrubs. This includes common and
weedy grass vegetation (such as Brachiaria
mutica and Panicum maximum) and
wetland herbs (including Commelina
diffusa, Cyperus malaccensis and Phragmites australis) which predominate.
There are also isolated shrubs such as Lantana
camara present along the Meander. The river course forms a regionally significant
landscape resource and a distinctive feature within the assessment area, has a
low ability to accommodate change and is therefore considered to have a high
sensitivity.
LR9.2
Natural Stream at Ha Wan Tsuen
One natural stream/meander bisects the fish ponds
at Ha Wan Tsuen North. The bank characterised by a combination of coarse
grassland punctuated by small areas of shrubs. The edges of the channels share
a common species composition to that described for the river course described
above. As an important component of the fishpond landscape this LR forms a
regionally significant landscape resource, has a low ability to accommodate
change and is therefore considered to have a high sensitivity.
LR9.3
Natural Stream at Lok Ma Chau Tsuen and Ping Hang
Two streams have been modified over time to form
part of the fishpond landscape. The streams are fed by watersheds on the Lok Ma
Chau ridge before flowing northwest to join the river meander. The upper course
of each of the streams follows the existing landform carving out gullies which
are characteristically lined by grass and shrub growth before adopting an
engineered form where they meet the flat plane of the fishpond landscape. Owing
to factors such as the natural character of the upper reaches of each stream
and their integration with the regionally significant fishponds these LRs are
considered to low ability to accommodate change and so have a high
sensitivity.
LR 9.4
Natural Stream at Ma Tso Lung
The natural stream course at Ma Tso Lung extends
from the uplands of Lok Ma Chau ridge crossing the grassland of the valley
floor before joining the fishpond landscapes in the northeast of the assessment
area. The upper reaches of the stream course is lined by grass and shrub growth
signalling the location of the watershed before adopting a more engineered
alignment in the northern portion of the grassland. The natural character of this stream and its
integration within the grassland landscape makes this LR less susceptible to
change with a medium ability to accommodate change resulting in a medium
sensitivity.
LR10 Engineered Water Channels
These water
channels have been engineered or channelized as part of drainage improvements
for the coastal plain and lowland areas in NWNT since the 1990s to resolve the
flooding problem in these areas. The resources are characterised by their
engineered nature with the straightening of their alignments, modification of
the banks with concrete retaining structures and their associated access and
maintenance roads. The common riparian plants found on the concrete banks of
the engineered water channels include Brachiaria
mutica, Commelina diffusa, Phragmites australis and Sesbania javanica.
LR10.1 Engineered Water Channel (Shenzhen River)
The engineered water channel to the north of the
LMC Loop defines the territory of HKSAR and Shenzhen, China. The channelized
Shenzhen River has been widened or modified in phases for the drainage
improvement of coastal plain and lowland areas of NWNT. The largest of the
engineered water channels within the assessment area this LR is dominant
feature in the landscape and although it has been disturbed by engineering works it contributes to the landscape character
and visual amenity of the local landscape context. This LR has a high ability
to accommodate change and so is considered to have a low sensitivity.
LR10.2 Engineered Water Channel (along Cross-boundary Facilities)
This LR extends north from San Tin Interchange and
follows an alignment to the west of the Cross-boundary facilities before
joining the Shenzhen River to the east of the LMC BCP. It effectively forms the
eastern boundary of the Sam Po Shue fishpond area. It is characterised by the
straight, engineered form of the channel and is lined by tree and shrub
planting designed to screen views of the Cross-boundary Facilities to the east.
Some 450 trees are located in planting areas along sides of the Channel, they
are largely exotic species such as Casuarina equisetifolia and Hibiscus tiliaceus in combination of quite a large number of
self-seeded weeds Leucaena leucocephala.
Owing to factors such as the engineered form and location this LR is considered
to have a high ability to accommodate change and so has a low sensitivity.
LR10.3 Engineered Water Channel (Lok Ma Chau Road)
Extending west from the LMC Road this engineered
water channel was designed to provide drainage improvements for the lowland
landscape adjacent to Chau Tau Tsuen. The channel is lined to the north and
south by tree planting screening both the channel and the adjacent viaduct of
the LMC Spur Line in views from the east. Some 300 trees are located in
planting areas along sides of the Channel; they are largely exotic species such
as Casuarina equisetifolia, Cleistocalyx operculata and Eucalyptus
tereticornis.
As a result of the engineered appearance of this LR, its relatively small size
and the proximity of the existing tree planting result in a feature which has a
high ability to accommodate change and is considered to have a low
sensitivity.
LR10.4 Engineered Water Channel (Newly constructed water channel at Ma
Tso Lung)
Located to the
north and east of Tse Koo Hang this engineered water channel is designed to
provide flood relief for the agricultural valley floor. The channel has a south
east – north west alignment feeding into the network of fishponds to the north
of the village. Owing to the recent
nature of the construction works this LR is considered to have a high ability to
accommodate change and a low sensitivity.
LR11 Marsh
The main areas of
marshland are found to the west of Hoo Hok Wai and Ma Tso Lung and small scale
marshland located at the western side of the LMC Loop. In addition the
assessment area contains compensatory marshland established to the east of LMC
Cross-boundary Facilities to reinstate and alleviate the marshland habitat
affected by the development of the facility and the LMC Spur Line. These
marshes are largely areas of former fishponds or agricultural lands which have
become disused with time and colonised by natural plant species. The dominant
vegetation in the marshland areas is formed by herbaceous species (including
grass Brachiaria mutica, Leersia hexandra and Panicum paludosum, and other herbs Cyclosorus interruptus, Colocasia esculenta
and Ipomoea cairica). Smaller numbers
of wetland herbs such as Cyperus spp.,
Phragmites australis and Ludwigia
octovalvis are also present. The ecological impact assessment suggests that
the dominance of herbaceous species indicates that part of the marsh areas has
been disturbed and is in the process of drying up.
Other areas
include small marshes developed from low-lying abandoned agricultural land
including the area to the southwest of Shun Yee San Tsuen. These areas are
ecologically linked with adjacent seasonally wet grassland and support a
limited but typical species composition with the marsh area mainly covered by
the fern Cyclosorus interruptus and
grasses (Panicum maximum and Brachiaria
mutica). Other wetland-associated herbs include Alternanthera sessilis, Commelina diffusa, Ludwigia perennis, Ludwigia
octovalvis and Colocasia esculenta.
LR11.1 Marsh on the Loop
The central
portion of the LMC Loop contains a number of fragmentary marshland areas representing
low-lying parts of the modified landform where the water has collected and the
area turned to marsh. The species composition of these areas shares many of the
plants which are characteristic of other marshlands within the assessment area.
This LR is not mature and fragmented, and is not regionally important and not
distinctive LR in the local area. Therefore marshlands are considered to be
susceptible with a medium ability to accommodate change and a medium
sensitivity.
LR11.2 Marsh at Hoo Hok Wai
Approximately
seven marshland areas are located within the fishponds to the east of the LMC
Loop at Hoo Lok Wai. These areas form a successional stage in the return of
disused fishponds to dry land and represent a loss in the distinctive landscape
texture of the organically shaped fishponds. Some 160 self-seeeded trees
spreading from adjacent woodland located at the southern edge of the marsh near
the Boundary Patrol Road including species Cleistocalyx
nervosum, Cratoxylum cochinchinense and Macaranga tanarius etc.. This marsh
area is considered to be a locally important LR and owing to factors such as
its size, the nature of the vegetation and its appearance it is considered to
have a low ability to accommodate change (including the eventual development of
grassland and woodland scrub) and has a high sensitivity.
LR11.3 Marsh at Lok Ma Chau Tsuen
This LR forms an
area of agricultural land to the north east of Lok Ma Chau Tsuen at the foot of
the wooded hill slopes which has reverted to marshland and includes wet
agricultural land which has evolved into marshland with declining agricultural
use. Given a combination of its location and the importance of the LR to the
local landscape it is considered to have a low ability to accommodate change
and has a high sensitivity.
LR11.4 Marsh at Chau Tau
This area of
marshland is thought to have developed from a combination of fishponds and wet
agricultural land and shares a similar appearance and species composition to
the other marshlands with the same origin. The marshland is characterised by a
combination of coarse grassland and marshland species, and forms an important
component in the setting of the surrounding villages. Some 50 trees are located
at the edge of the marsh near Lok Ma Chau Water Channel including species Casuarina equisetifolia and Cleistocalyx operculata. Given its
location, contribution to the existing landscape setting and the nature of the
LR it is considered to have a low ability to accommodate change and a high
sensitivity.
LR11.5 Mitigation
Wetland and Reedbed at MTR LMC Station
Located to the
east of the MTR LMC Station this area forms a created wetland and reedbed
designed as part of the mitigation for the LMC Spur Line. Some 165 trees are
located near the storage pond and along the Spur Line, they are largely exotic
species Casuarina equisetifolia.
Although relatively large in size and it contributes to the local landscape
setting and is considered to have a low ability to accommodate change and a
high sensitivity.
LR12
Developed Area and Roads
This resource
contains a combination of road and highway, residential and industrial
development types which are characteristic of the rural areas of the North West
New Territories (NWNT). These include the conversion of agricultural fields to
light industrial buildings and small scale workshops. This resource occupies a
relatively limited extent of the assessment area which is largely characterised
by natural landscape resources such as grassland, mixed woodland and fishponds.
The main area is found at the east of MTR LMC Station, at the entrance of Ha
Wan Tsuen and at the south of WCR located alongside the Fanling and San Tin
Highways. The roadside tree planting associated with these LRs is discussed
under LR4. The replacement of the agricultural fields by these developments
within the rural areas has significantly degraded the landscape and visual
amenity of the area and so the LR is considered to have a low value. Overall
given the piecemeal nature of its distribution and level of development within this
area it is considered to have a high ability to accommodate change and a low
sensitivity.
LR12.1 San Tin
Developed Area and Roads
This LR located to the southwest of the assessment
area is characterised by a combination of infrastructural development including
the San Tin Highway – Fanling Highway, the San Tin Interchange and the roads
associated with the LMC BCP. The road corridors are lined by common tree
species which are described under LR4 Tree Planting. Given the extent
of the development in this area it is considered to have a high ability to
accommodate change and hence has a low sensitivity.
LR 12.2 Lok
Ma Chau Developed Area and Roads
Located to the east of the MTR LMC Station, north of the Spur Line viaduct and square
and sportground in front of Ha Wan Tsuen, this LR includes access roads and
associated infrastructure development and is connected to the maintenance road
for the Shenzhen River. Some 200 tree planting are found in these developed
areas including species Albizia lebbek,
Casuarina equisetifolia, Hibiscus tiliaceus and Lagerstroemia speciosa etc.
In addition, LMC Police Station is located on a knoll to south of LMC Tsuen is
a Graded 2 Historical Building which forms part of this LR, and is still under
operation refer to heritage assessment in Chapter 10 of this EIA. Boundary
Patrol Road and Lok Ma Chau Road are the main road corridors. As result of its
utilitarian function this LR is considered to have a relatively high ability to
accommodate change and a low sensitivity.
LR12.3 Ma
Tso Lung Developed Area and Roads
The road
infrastructure and built areas which forms this LR is located at the
south-eastern edge of the assessment area to the north of the Lo Wu
Classification Range and extends north to MA Tso Lung San Tsuen. This LR also covered two built structures
including the HKPF Lok Ma Chau Operation Base adjacent to Boundary Patrol Road
and a tunnel portal at Ma Tso Lung Road for regional waterpipe maintenance. In
addition, MacIntosh Fort is located on the hill to the east of Ma Tso Lung
Tsuen is a Graded 2 Historical Building which forms part of this LR refer to
heritage assessment in Chapter 10 of this EIA. Some 63 trees are located within the built areas including species Acacia confusa, Macaranga tanarius and Pinus
elliottii etc.. The road corridor is lined by tree planting and secondary
woodland however it has little intrinsic value as an LR. As such the LR has a
high ability to accommodate change and a low sensitivity.
LR13 Open Yards
Open yards form
one of the major development intrusions within the NWNT and were developed in
response to the rapid development of transportation and trading between Hong
Kong and China which lead to an increasing demand for container storage areas
since the 1980s. Opportunities for new storage locations within the urban area
are limited and so some abandoned agricultural fields adjacent to village
settlements in NWNT were utilised due to their proximity to cross-boundary road
corridors and facilities. These agricultural fields were transformed with the
construction of concrete hard standing for container storage and car/lorry
parking areas. Given the level of disturbance caused by these facilities this
use of the land is not considered to be visually compatible with the rural
landscapes. Overall this resource is able to accommodate extensive change,
hence, is considered to have a low sensitivity.
LR13.1 San
Tin Open Yards
The open storage yards adjacent to the San Tin
cover an extensive part of the local landscape to the south of the San Tin and
Fanling Highways. The areas are bounded to the east and west by mixed woodland
on the lower hill slopes of the surrounding uplands. The area contains a number
of concrete covered compounds interspersed by car/lorry parking, access tracks
and covered with storage containers. Some 20 trees are located at the edge of
open container including species Ficus benjamina, Leucaena leucocephala and
Macaranga tanarius. As a result of the level of disturbance this area is
considered to have a high ability to accommodate change and a low sensitivity.
LR 13.2 Lok
Ma Chau Open Yards
Extensive areas of car/lorry parking and open
storage yards are located to the north of the San Tin and Fanling Highways
infilling the spaces between the village settlements such as Wing Ping Tsuen, Chau Tau and Pun Uk Tsuen; and infrastructure including
the road network and LMC Spur Line related facilities. These pockets of open
yards, open car parking and light industry are largely surrounded by tree
planting including the woodland planting to the east and west of the Cross-boundary Infrastructure and Facilities (Lok
Ma Chau Vehicular Areas). Some 570 trees are found at the periphery of
individual lots including species Acacia
confusa, Ficus
benjamina, Leucaena leucocephala and Macaranga tanarius. The landscape represented by this LR is highly
disturbed, has a high ability to accommodate change and a low sensitivity.
LR13.3 Ma
Tso Lung Open Yards
This LR includes relatively small areas of light
industrial units located to the south of Ma Tso Lung San Tsuen within a
landscape setting of agricultural fields to the west and mixed woodland to the
east. The area is characterised by an area of concrete hard standing covering the site and a number of industrial
sheds to the east. Another area disturbed as part of the recently constructed
engineered channel is located to the north adjacent to the settlement of Shun
Yee San Tsuen. Formed as a narrow, rectilinear area it is bounded to the east
and west by the wooded hill slopes which form the valley landscape. As both of
these areas have been significantly modified they have a high ability to
accommodate change and a resulting low sensitivity.
For the purposes
of this assessment the landscape resources are represented by the existing land
coverage. The condition of these landscape resources is also important in
determining the landscape quality of the assessment area and its sensitivity to
change as described above. Therefore the preservation and enhancement of the
existing landscape resources is important to the successful integration of the
proposals within the landscape context of the assessment area.
The location and
extent of the LRs are shown on Figures 11.2a to 11.2e and photographs of LRs are provided on Figures 11.2f to 11.2w. Table 11.5.2 provides an assessment of
the sensitivity of each of the identified LRs.

11.5.1.3 Landscape Character Areas
The landscape character of the assessment area
comprises of the Sam Po Shue lowland rural landscape, LMC Cross-boundary infrastructure
and facilities landscape, lowland rural landscape, LMC
hillside landscape, Ma Tso Lung lowland rural landscape, LMC Loop riverside
landscape and Hoo Hok Wai lowland rural landscape. The detailed descriptions of
the landscape character are provided in this section whilst Figures 11.3a to 11.3e show the extent of the identified LCAs and Figure 11.3f
provides photographs of the character areas.
LCA1 Sam Po Shue Lowland Rural Landscape
This LCA is located to the west of the assessment
area and is characterised by extensive
fishponds to the south of the Shenzhen
River with their largely rectilinear form separated by earth bunds, access
tracks and a natural stream courses. This LCA is an important landscape
character in NWNT providing an extensive lowland landscape from west to north along the south of
the Shenzhen River. This landscape contrasts with the character of the densely
developed areas in Shenzhen, Fu Tian to the north of the Shenzhen River. Given
its importance to the landscape of the region it is considered to have a high
sensitivity.
LCA2 LMC Cross-boundary Infrastructure and Facilities Landscape
The LMC area is dominated by the
structures associated with the boundary crossing
facilities including the vehicular crossing and the buildings and viaduct
associated with the East Rail LMC Spur Line. The
vehicular crossing is characterised by the extensive apron for waiting
vehicles. The railway
crossing is characterised by the modernity of the building and the preserved and
enhanced wetland areas (fishponds) to the south, east and west. This LCA is
important as a gateway to HKSAR although the landscape quality of the vehicular
crossing is degraded by its functional requirements. The railway crossing has
given greater consideration to the landscape character of the area although the
structures are still dominant within the LCA. Given the level of existing
development within this LCA it is considered to have a relatively low
sensitivity.
LCA3 San Tin Lowland Rural Landscape
This LCA located along the south western
boundary of the assessment area is bounded by the LMC Cross-boundary Infrastructure and Facilities to the east, and extensive fishponds
to the north and west at Sam Po Shue. The
character of this area is composed of 3-storey high village settlements and
open yards currently utilised for car parking and open container storage. The
main village settlements which include Wing Ping Tsuen and Tung Chan Wai are
located at the southern part of the LCA whilst open storage yards from the
major character to the north along the cross-boundary infrastructure corridor. As the local context is largely
interrupted by the cross-boundary
facilities, highways and open yards which have relatively less landscape value,
it is considered to have a low
sensitivity.
LCA4 Ki Lun Shan Lowland Rural Landscape
This LCA covers the lower slopes of Ki Lun Shan bounded by the Fanling Highway to the north and mixed woodland to the south. Scattered village houses, open storage areas and light industrial units line the edges of the highway extending into the hinterland and are punctuated by small tree groups and individual trees. The two main areas of development are separated by a vegetated spur of the Ki Lun Shan which runs through the centre of the LCA. The main areas of village housing are located to the north and south. The highway corridor is characterised by mature roadside tree planting which contains views along the carriageway. Given the combination of the development and the natural landscape within this area it is considered to have a medium sensitivity.
LCA5 LMC Lowland Rural Landscape
This LCA covers the areas alongside the
LMC Road, Ha Wan Tsuen Road and existing Boundary Road. It is a linear piece of
lowland landscape bounded by the Fanling Highway to the south, LMC Cross-boundary facilities to the west, low ridges to the east and fishponds to the
north along the abandoned meander. Major village settlements within the area
include Chau Tau, Pun Uk Tsuen, Ha Wan Tsuen and LMC Tsuen. Its network of
associated fishponds and agricultural fields are dominated to the west along the roads by the structures associated with the LMC Cross-boundary facilities and LMC Spur Line in the background. In contrast a more
natural setting with less urban and developed intrusion extends from Hoo Hok
Wai in the east. This landscape is dominated by fishponds, scattered village
houses at Ping Hang and Tse Koo Hang and vegetated lower slopes in the
background to the south of the Boundary Road. The rural landscape of this area
forms the counterpoint to the urban setting of Shenzhen to the north. Although
the western portion of this LCA has been disturbed by infrastructural
development the majority of eastern portion maintains its original lowland
character and hence it is considered to have a medium sensitivity.
LCA6 LMC Hillside Landscape
This LCA covers the hillside landscape of
low ridges extending from LMC to Tai Shek Mo. Although the ridge has an
elevation of not more than +120mPD, it is a dominant landscape feature in the
NWNT lowland plane that visually links to Sandy Ridge and Ki Lun Shan to the
east and south, particularly in the elevated views from Shenzhen. It also forms
a green backdrop to the south of the LMC Loop when viewed from the banks of the
Shenzhen River to the north and screens the views from Kwu Tung and other
village settlements in the hinterland to the south east along the Fanling
Highway. The higher elevations of these ridges are covered by a tapestry of shrub
and coarse grassland whilst the lower elevations adjacent to villages and
fishponds are dominated by mixed woodland. As this LCA forms the green backdrop
to many of the views available in the lowland within the assessment area it is
regarded as an important landscape feature contrasting with the dense urban
development to the north of the Shenzhen River. Given its importance to the
landscape of the region it is considered to have a high sensitivity.
LCA7 Ma Tso Lung Lowland Rural Landscape
This LCA covers Ma Tso Lung and part of
Fung Kong Shan village settlements on the lower slopes and within the side
valleys which cut through the LMC ridge, Fung Kong Shan and Tai Shek Mo. The
landscape character of this area features scattered village house clusters and
their network of associated agricultural fields and fishponds. This natural and
low profile setting contrasts with the industrial and infrastructural
development in Kwu Tung adjacent to the Fanling Highway. There are also a
number of marshes identified in Ma Tso Lung to the west of village settlements
which have naturally evolved from former fishponds and agricultural fields.
Given the significance of its rural landscape character forming a buffer to Hoo
Hok Wai wetland area, this LCA is considered to have a medium sensitivity.
LCA8 LMC Loop Riverside Landscape
The LMC Loop; bounded by the engineered Shenzhen River to the north and the abandoned river meander to the east, south and west; has become an island as a result of the river training works for the Shenzhen River. The vehicular access bridging the meander to the west and running along the northern periphery of the LMC Loop also serves as maintenance access for the river channel. The landscape of this area is dominated by coarse grassland with a small orchard at the southwest corner of the LMC Loop and marshes in the central and south-eastern portions adjacent to the meander. These marshes have naturally evolved from the filling of the abandoned fishponds and areas where surface water has collected. With the exception of banana trees within small orchard areas tree growth is limited to a relatively small number of self-seeded trees naturally spreading from adjacent woodland. The majority of the LMC Loop area was disturbed by the river training works and so its character is quite different and fragmented from the adjacent lowland areas which are dominated by fishponds at Sam Po Shue and Hoo Hok Wai. The overall sensitivity of the LMC Loop is considered to be medium although there are areas including the marshes and abandoned meander which are considered to have a higher sensitivity.
LCA9 Hoo Hok Wai Lowland Rural Landscape
This landscape is composed of abandoned
fishponds and marshlands which are major landscape components of the natural
lowland character extending from Deep Bay to Mai Po to Sam Po Shue and Hoo Hok
Wai. The marshes in this area have naturally evolved from abandoned fishponds
or agricultural fields. Following the decline of agricultural activity in the
territory since 1980, the area of marshland is expanding into Ma Tso Lung. The
northern edge of Hoo Hok Wai was largely disturbed by the river training works
for the Shenzhen River and a maintenance access for the river channel and forms
the only developed element within this natural setting. Given the local
significance of these marshes and their unique lowland character extending from
the landscape of Deep Bay, this LCA is considered to have a high sensitivity.
These LCAs are mapped on Figures 11.3a to 11.3e and photographs of the LCAs provided on Figure 11.3f. Table 11.5.3 provides an assessment of the sensitivity of each of the identified LCAs.

11.5.2 Landscape Impact Assessment
With
reference to Section 2.3.4.1 and Figure
2.1a of the EIA Report, the LMC Loop
Development is composed of proposed uses of higher education, high-tech R&D
and C&C industries. The proposed development will have an estimated total
number of workers and students for the LMC Loop of approximately 53,000, based
on a maximum Gross Floor Area (GFA) of 1,200,000m2and an overall plot ratio of
1.37. The provision of open spaces, amenity areas, and an ecological area, which
comprise about 12%, 18% and 15% of total site area respectively, are also
included in the RODP. The RODP shown on Figure 2.1b has incorporated a more
dynamic height profile with gradation in building heights for the LMC Loop in
response to the general environment of the area. Existing level of the LMC Loop
is currently relatively flat at a level of +4.5 to +6.0mPD. The drainage impact
assessment indicates that site formation levels at about +5.90mPD would be
adequate in terms of coping with the risk of flooding.
The following design
considerations are incorporated into the proposed development framework on the
LMC Loop during the formulation of RODP to avoid the impact on landscape
resources and existing landscape characters, visually pleasant resources and
visual quality of visually sensitive receivers, maximize the preservation of
landscape resources such as existing trees, roadside and channelside planting
areas, woodlands, fishponds and wetlands, and maximize the integration of the
proposals with the existing landscape character and visual context etc. including:
·
Creation of 12.8 ha Ecological Area (EA) to south of LMC Loop to enhance both ecological and landscape context
as well as maintain the riverside landscape.
·
Creation of 50m wide landscape buffer zones between the Shenzhen River in the north and the Ecological Area in the south to the proposed development. Besides,
other 20 to 30m wide landscape areas are reserved along the eastern and western periphery of
the LMC Loop. These landscape buffers will maximize the preservation of trees
and will form the tree transplanting final location and compensatory planting
for trees affected within the LMC Loop.
·
Responsive
plot ratio and building height profiles with regards to the
adjacent infrastructure and rural landscape characters. Within the framework of 1.2Mm2 GFA, the overall plot ratio
will be 1.37. The building height profile was formulated with regard to the public comments and amenity/activity corridor. The
low-rise building will be placed at the south and east of LMC Loop to minimize
the impact to flight lines and Ecological Area. Tallest buildings will be located at the western and
central part of LMC Loop, where ecological sensitivity is relatively less. The
tallest buildings will be approximately 12 storeys from ground level (about
54mPD). It serves as a primary gateway for the site. Building heights along the Shenzhen River would be of
lower rise and gradually rise towards the
centre of the site and again gradually decrease towards the southern boundary of the site. Furthermore, the building height of
the commercial sites near Hoo
Hok Wai has been reduced to minimize the impacts of the proposed buildings on the birds’ flight paths. These
stepped building height profiles will create a better integration with the
rural landscape setting within HKSAR boundary and high-rise urbanized setting
in Shenzhen in the north across the river.
·
Flushing
Water Service Reservoir at Horn Hill: There is a need to maintain adequate head for flushing water supply. In order to save pumping energy
for individual buildings, the flushing
water service reservoir would be located at Horn Hill, which is the highest hill near LMC Loop. In general, the
grassed hill is less sensitive to development than more sensitive landscape
resources such as woodlands.
·
Sewage
Treatment Works (STW) for treatment of sewage arising from
the development of LMC Loop is sited at southeast corner of LMC Loop which is
the optimum location on site to handle sewage. The buildings of sewage treatment works will be low rise and there will be minor human
activities. Thus it has benefits on minimizing ecological and landscape and
visual impacts when compared with the alternative site at other locations
within LMC Loop.
·
Creation of 10.6
ha of Open Space within the proposed development and 15.9 ha of Amenity/Activity Corridor in north-south direction at centre of LMC Loop with provision of
both active and passive recreation facilities for the use of future users,
greening in form of tree and shrub planting, green wall and green roof system.
These greening measures will enhance the quality of the landscape and visual
context. The east-west and north south orientation of open space and amenity
core also serves as major view corridors and breezeways for the LMC Loop
Development.
·
In order to support the future development and
population in LMC Loop, associated infrastructures will be required
including Drainage System under Internal
Transport Networks and Sewage Treatment Works within the LMC
Loop. Besides there are some associated infrastructures are proposed outside
the LMC Loop including Eastern and Western Connection Roads from the Loop to Ma
Tso Lung and Kwu Tung, San Tin and Fanling Highways respectively, Direct Link to MTR LMC Station and Flushing Water Service Reservoir.
Due to the scale of the LMC Loop Development
project, there are some adverse impacts on the existing landscape characters of
the lowland and hillside areas at the north New Territories from LMC to Ma Tso
Lung although sensitive areas such as Sham Po Shue located to the west of the
LMC Station will be spared impact due to the implementation of the project.
The institutional development and associated
utilities and road networks on the LMC Loop would introduce urban components
into the existing rural riverside context which is currently only composed of
grass, marsh, reed beds and tree clusters with very little urban and human
disturbance. Although there are significant change of landscape character from
rural to institutional landscapes, the introduction of landscape buffer,
Ecological Area and landscaped open space and amenity areas, greening provision
on podium, building façade and roof would make the development on the LMC Loop
a better integration with surrounding rural context. It should be noted the urbanised and
high-rise context at Shenzhen to the north of LMC Loop have been formed the
background of the proposed development.
The impact on the landscape character of the LMC Loop has been hence
largely reduced against this urbanised background.
Besides, there are some associated
infrastructure and utilities works proposed outside the LMC Loop. Given to the
scale of these works, impacts on the rural and hillside landscape characters to
the south of the LMC Loop is not significant. These works include Western and
Eastern Connection Roads, Direct Link to MTR LMC Station and Flushing Water
Services Reservoir. The responsive selection of road alignment and location of
reservoir follows largely existing Boundary Patrol Road and on grassed Horn
Hill that would significantly reduce the impacts on landscape resources and
hence the Hoo Hok Wai and LMC hillside landscape characters. The use of
depressed and underpass road connection from Hoo Hok Wai to the LMC Loop will
further reduce the visual intrusion of engineering structures in lowland
fishpond areas. The Direct Link To the MTR LMC Station is designed in form of
viaduct aligned with existing Spur Line that would have a better integration
with existing character of the cross-boundary facilities at LMC.
In addition
to the LMC Loop Development under Schedule 3 mentioned above, refer to Section
2.4 and Figure
2.1a
to 2.26c
of the EIA Report, the following associated infrastructures proposed within or outside the LMC Loop are Designated Projects (DPs) under
Environmental Impact Assessment Ordinance (EIAO) Schedule 2, they have been
also considered as part of the landscape impact
assessment:
Ecological Area (DP1)
·
Ecological Area
(EA) located at the southern portion of the LMC Loop for the creation of reed
bed along the meander and the replacement of wetlands within the LMC Loop to
compensate the loss of mash and reed bed due to the proposed development. The
EA will also enhance the visual quality and character of LMC riverside
landscape.
Western Connection Road (DP2)
·
The proposed road
largely utilises existing road corridors such as Fanling and San Tin Highways,
LMC Road and Ha Wan Tsuen Road with road widening/improvement works and traffic
circulation rearrangement to accommodate standard footpath and new cycle tracks
and new planting areas along roads and in central median. The works area has
been fine tuned to maximise the preservation of mature trees along Lok Ma Chau Road
and Ha Wan Tsuen Road to maintain visual quality of rural areas.
Direct Link to MTR LMC Station (DP3)
·
The alignment of
this railway connection largely follows the alignment of existing Spur Line
when approaching MTR LMC Station to create a better visual integration with
existing infrastructure landscape and less intrusive to existing rural
landscape. The impact on existing MTR mitigation wetland and fishponds in Ha
Wan Tsuen will be reduced through the use of viaduct instead of at-grade
railway structures. Besides, an elevated PTI will be built on top of existing
PTI at ground floor of LMC Station extending from existing LMC Station. The
introduction of viaduct and elevated PTI will be visually integrated with the
existing Spur Line, LMC Station and surrounding cross-boundary facilities.
Drainage System under Internal
Transport Networks (DP4)
·
Integrated
utilities and proposed road networks approach to maximise the provision of
roadside planting.
Sewage Treatment Works (DP5)
·
On site treatment with the “No net increase in pollution” approach avoids further impact on
landscape resources and characters as a result of the introduction of an
off-site sewage treatment plant and associated pipe connections. Putting the
facilities on the LMC Loop Development site has less visual intrusion than
other location options in surrounding rural areas. The STW is designed at-grade due to
cost-benefit consideration, reduced waste generation and reduced energy
consumptions compared with underground options. In terms of STW design,
screw pumps will not be used to minimize visual impact.
Eastern Connection Road (DP6)
·
The proposed road
largely utilises the
existing Boundary Patrol Road with road widening/improvement works to accommodate standard footpath
and new cycle tracks and new planting areas along road and in central median.
The works area has been fine tuned to maximize the preservation of mature trees at Tse Koo Hang. Besides, depressed and
underpass roads are designed for the section at Hoo Hok Wai and LMC fishpond
areas and across the meander connection to road network on the LMC Loop to
minimize the impact on landscape resources, existing riverside and lowland
landscape characters and visual context instead of using at-grade road.
Flushing Water Service Reservoir
(DP7)
·
The proposed
location
of this reservoir on Horn Hill which is a grassed knoll and less
sensitive to development than woodland. The proposed half-sunken reservoir
structure responds to the topography of the hill and located away from VSRs
thus minimizing the
visual intrusion of engineering structures in the hillside landscape.
The DPs are described in Chapter 1 and 2 of the EIA Report. Other non-DP
components were also assessed. The level of detail for the DPs is subject to
further refinement at the detailed design stage and is provided to the best
knowledge available for the purpose of the assessment.
A Landscape Impact Assessment has been undertaken to define the nature and scale of landscape impacts associated with as a whole the proposed development within the LMC Loop, and the associated infrastructure and utilities facilitating the development including the proposed ECR, WCR, Direct Link to MTR LMC Station and the Flushing Water Service Reservoir. The impacts are discussed specifically in terms of the existing landscape character and resources within the HKSAR boundary. Landscape and visual mitigation measures have been identified for the LMC Loop Development as a whole and their effectiveness and landscape opportunities explored. The acceptability of the development options will derive from the scale of residual impacts and the ability of the proposals to mitigate them to acceptable levels.
The
assessment findings will inform the future detailed development proposals
within the LMC Loop and the design of its associated infrastructure and utility
development options. The conceptual development proposals will be formulated
through an iterative design process, further refined and developed to
accommodate the future institutional design requirements, and to minimise the
predicted residual landscape impacts. As the development proposals may be
further refined the assessment assumes the worst case scenario in terms of the
impacts.
The source of impacts of each DPs
under schedule 2 on the existing landscape context
includes the following:
·
SO1
(DP1, DP4 & DP5)– Implementation of development on
LMC Loop, and the associated infrastructure and utilities facilitating the
development and site formation works.
·
SO2
– (DP6) Eastern Connection Road from Ma Tso
Lung to the Loop composed of at-grade, depressed and
underpass sections of the road works.
·
SO3
(DP2)– Western Connection Road from San
Tin Highway through Lok Ma Chau
Road and Ha Wan Tsuen Road to the Loop composed of
mainly road widening works, construction of slip road from LMC Road to San
Tin Highway and realignment of
NWNT cycle track.
·
SO4
(DP7) – Flushing Water Service Reservoir and associated access road at Ping Hang.
·
SO5 (DP3) – Direct Link from the WCR to MTR LMC
Station composed of mainly the construction of viaduct and PTI.
11.5.2.1 Predicted Impacts on Existing Landscape Resources
The predicted impacts on the Landscape
Resources of the
assessment area during construction and operational
period would be as
follows:
·
Landscape
impacts on the existing reed bed and grassland as a result of site formation
works for the development of LMC Loop and
associated infrastructure and utilities facilitating the development (DP4 and
DP5) although the
proposals have sought to reinstate and create
new reed bed (DP1) as part of the landscape and ecological mitigation approach.
·
Landscape
impacts on the existing low-lying fishpond and rural landscape character
resulting from the introduction of low density institutional developments and associated infrastructure and utilities
facilitating the development (DP4 and DP5) on the LMC Loop. The existing flat topography
will be substantially changed to accommodate the built components.
·
Loss
of existing trees will be limited to trees within the Loop and alongside the
proposed Direct Link to MTR LMC Station (DP3), WCR (DP2) and ECR (DP6); and access road for the Flushing Water
Service Reservoir (DP7).
A large proportion of these trees have naturally colonised the site and
their overall amenity value is not considered to be high. Based on the broad
brush group tree survey contained in Appendix
11-1, the following table provides a summary of preliminary tree impacts
arising from the implementation of the proposed works. An individual tree
impact assessment will be prepared during the detailed design stage of the
project in accordance with ETWB TWC No. 3/2006 Tree Preservation and a formal
tree felling application submitted for Government approval. The estimated
number of felled / transplanted trees is presented in Table 11.5.4

There are approximately 6,660 existing trees on the LMC Loop and within the limit of works
areas. No Registered Old and Valuable Trees” and/or “Champion Trees are found.
Loss of existing trees will be limited to trees within the Loop and alongside
the proposed Direct Link to MTR LMC Station, WCR and ECR; and access road for
the Flushing Water Service Reservoir. A
large proportion of these trees have naturally colonised the site and their
overall amenity value is not considered to be high. Based on the broad brush
tree survey contained in Appendix 11-1 and the preliminary engineering layouts
of proposed works contained in Chapter 2 of this EIA, approximately 279 trees are proposed to be transplanted to new planting areas
proposed on the LMC Loop and alongside of proposed road improvement works, and
approximately 4,022 trees are
inevitable to be in conflict with the construction works and recommend for
felling. The above recommendation on existing trees is preliminary based on
project information available at this stage and subject to the detailed tree survey and tree felling application to be
submitted for LandsD/Government approval at detailed design stage of the
project in accordance with ETWB TWC No. 3/2006 Tree Preservation.

Table 11.5.5 describes the
source of impacts as a result of the proposed LMC Loop Development and the associated
infrastructure as a whole DP under Schedule 3 and presents the magnitude of
change on individual LRs. The predicted impacts to LRs and the magnitude of
change for individual LRs are shown on Figures 11.4a to 11.4s and are described as follows:
Large
According to the assessment summarised in Table 11.5.5, the magnitude of change for individual LRs including areas associated with the LMC Loop and WCR will be relatively large or result in the loss of this LR as a result of the site formation works on the LMC Loop for accommodating road and utilities works, creation of EA and construction of the slip road of WCR and so the magnitude of change would be large. These LRs include Roadside Planting along Fanling and San Tin Highways (LR4.2), Trees on the Loop (LR4A), Grassland on the Loop (LR6.1), and Marsh on the Loop (LR11.1).
Intermediate
For other areas also directly affected by the road improvement works for WCR and ECR and the construction of viaduct for a Direct Link to LMC Loop including Ha Wan Tsuen Road Mixed Woodland (LR3.1); Roadside Planting along Lok Ma Chau Road and Ha Wan Tsuen Road (LR4.3 and 4.4); Lok Ma Chau Agricultural Fields (LR7.3); Lok Ma Chau Road Engineered Water Channel (LR10.3), Mitigation Wetland and Reedbed at MTR LMC Station (LR11.5) and Ma Tso Lung Open Yard (LR13.3) the magnitude of change would be intermediate.
Small
The magnitude of change for individual LRs, including the following would be small as a result of the implementation of the proposed scheme. These include the Cross-boundary Infrastructure and Facilities (MTR LMC Station) (LR1.1); Cross-boundary Infrastructure and Facilities (Lok Ma Chau vehicular) (LR1.2); Cross boundary Infrastructure and Facilities (Lok Ma Chau Bus Terminal) (LR1.3); Ha Wan Tsuen Village Settlement (LR2.1); Lok Ma Chau Road Village Settlement (LR2.2); Lok Ma Chau Road Mixed Woodland (LR3.2); Ma Tso Lung Mixed Woodland (LR3.4); Roadside Planting along Lung Hau Road (LR4.1); Ma Tso Lung Shrubland (LR5.2); Grassland at Ma Tso Lung (LR6.4); Ha Wan Tsuen Fishponds (LR8.2): Lok Ma Chau Fishponds (LR8.4); Hoo Hok Wai Fishponds (LR8.5); Natural River to the south of the Loop (LR9.1); Natural Stream at Ha Wan Tsuen (LR9.2); Natural Stream at Lok Ma Chau Tsuen and Ping Hang (LR9.3); Natural Stream at Ma Tso Lung (LR9.4); Engineered Water Channel (along Cross-boundary Facilities) (LR10.2); Marsh at Hoo Hok Wai (LR11.2); Mitigation Wetland and Reedbed at MTR LMC Station (LR11.5); San Tin Developed Area (LR12.1); Lok Ma Chau Developed Area (LR12.2); Ma Tso Lung Developed Area (LR12.3)and Lok Ma Chau Open Yard (LR13.2).

Open Yard.
Table 11.5.6 presents the predicted
unmitigated and mitigated (Day 1 and Year 10 / Residual) impacts on the
existing landscape resources resulting from the proposed works of LMC Loop Development under Schedule 3 during the construction and
operational phases of the project. The mitigated (residual) impacts are assessed during the design year (10 to 15 years after the schemes
opening) when the proposed mitigation planting is deemed to have reached a
level of maturity,
which is sufficient for it to perform the design objectives.
Significance
thresholds for the unmitigated impacts are summarised as follows:
Significant Adverse Impact
LRs experiencing significant
adverse impacts are those with a relatively higher sensitivity and magnitude of
change due to site formation works on the LMC Loop to accommodate the proposed
development and associated infrastructure and utilities works. The only LR
under this category is Marsh on the Loop (LR11.1) due to permanent loss of the immature
and fragmentised marsh on the Loop.
Moderate Adverse Impact
LRs subject to moderate adverse impacts are those which have a high to medium sensitivity including village settlements, mixed woodland, roadside tree planting, planting on the Loop, fishponds, natural river/stream and water channels, marsh and mitigated wetland and experience a small to intermediate magnitude of change due to site formation works on the LMC Loop to accommodate the proposed development and associated infrastructure and utilities works, road improvement works for WCR and ECR and construction of viaduct for Direct Link to LMC Station and slip road for WCR . These LRs include Ha Wan Tsuen Village Settlement (LR2.1), Ha Wan Tsuen Road Mixed Woodland (LR3.1),Lok Ma Chau Road Mixed Woodland (LR3.2), Ma Tso Lung Mixed Woodland (LR3.4), Roadside Planting along Lung Hau Road (LR4.1), Roadside Planting along Fanling and San Tin Highways (LR4.2), Roadside Planting along Lok Ma Chau Road and Ha Wan Tsuen Road (LR4.3 and 4.4), Trees on the Loop (LR4A), Grassland on the Loop (LR6.1), , Ha Wan Tsuen Fishponds (LR8.2), Lok Ma Chau Fishponds (LR8.4), Hoo Hok Wai Fishponds (LR8.5), Natural River to the South of the Loop (LR9.1), Natural Stream at Lok Ma Chau Tsuen and Ping Hang and Ha Wan Tsuen (LR9.2 and 9.3), Natural Stream at Ma Tso Lung (LR9.4), Lok Ma Chau Road Engineered Water Channel (LR10 .3), Marsh at Hoo Hok Wai (LR11.2) and Mitigation Wetland and Reedbed at MTR LMC Station (LR11.5).
Slight Adverse Impact
LRs which are subject to slight adverse impacts include those with a low to medium sensitivity, including cross-boundary infrastructure and facilities, shrubland and grassland, agricultural fields, water channel, developed areas (roads) and open yards and experience a small to intermediate magnitude of change due to road improvement works for WCR and ECR including construction of a new road section, and construction of viaduct for Direct Link to LMC Station and slip road for WCR. These include Cross-boundary Infrastructure and Facilities (MTR LMC Station) (LR1.1), Cross-boundary Infrastructure and Facilities (Lok Ma Chau Vehicular Area)(LR1.2), Cross boundary Infrastructure and Facilities (Lok Ma Chau Bus Terminal) (LR1.3), Lok Ma Chau Road Village Settlement (LR2.2), Ma Tso Lung Shrubland (LR5.2), Grassland at Ma Tso Lung (LR6.4), Lok Ma Chau Agricultural Fields (LR7.3), Engineered Water Channel (along Cross-boundary Facilities) (LR10.2), San Tin Developed Area and Roads (LR12.1), Lok Ma Chau Developed Area and Roads (LR12.2), Ma Tso Lung Developed Area and Roads (LR12.3), Lok Ma Chau Open Yard (LR13.2), Ma Tso Lung Open Yard (LR13.3).
Negligible Impact
In a number of locations the proposed works will not encroach upon the existing LRs and so there would be no perceptible change. These LRs include Lok Ma Chau Tsuen Village Settlement (LR2.3), Ha Wan Fishermen Village Settlement (LR2.4), Chau Tau and Pun Uk Tsuen Village Settlement (LR2.5), San Tin Village Settlement (LR2.6), Tai Law Hau Village Settlement (LR2.7), Ping Hang Village Settlement (LR2.8), Tse Koo Hang Village Settlement (LR2.9), Ma Tso Lung Village Settlement (LR2.10), San Tin Road Mixed Woodland (LR3.3), Roadside Planting along Ma Tso Lung Road (LR4.5), Lok Ma Chau Shrubland (LR5.1), Grassland at San Tin (LR6.2), Grassland at Lok Ma Chau, (LR6.3), Pun Uk Tsuen Agricultural Fields (LR7.1), Lok Ma Chau Tsuen Agricultural Fields (LR7.2), Ma Tso Lung Agricultural Fields (LR7.4), Sam Po Shue Fishponds (LR8.1), Lok Ma Chau Road Fishponds (LR8.3), Engineered Water Channel (Shenzhen River) (LR10 .1), Engineered Water Channel (Newly constructed water channel at Ma Tso Lung) (LR10 .4), Marsh at Lok Ma Chau (LR11.3) and LR11.4 Marsh at Chau Tau.
The following section
summarizes the unmitigated impacts on the existing landscape resources during
construction and operation phase as a result of individual DPs under Schedule
2.
SO1 - Development on the Loop (including DP1,
DP4, DP5)
The unmitigated impacts on the landscape
resources of the assessment area include a slight to significant adverse landscape impact due to the loss of the reedbed, marsh, natural stream and grassland of the LMC Loop during the
construction phase of the project. Trees on the Loop will be affected by the site formation works for
development sites and associated works for utilities and road networks, as
mentioned in Table 11.5.4, all weedy
trees are recommended to be removed, some existing trees along new Boundary
Patrol Road will be retained in the proposed landscape areas.
The landscape
impact as a result of the
construction of Ecological Area (DP1) Drainage System under Internal Transport
Networks (DP4) and Sewage Treatment Works (DP5) on the LMC Loop includes the followings:
· Significant Adverse on LR11.1 Marsh on the Loop
· Moderate Adverse impact on LR4A Trees on the Loop and LR9.1 Natural River (to the South of the Loop)
·
Slight Adverse impact on LR6.1 Grassland on
the Loop
SO2 - Eastern Connection Road (DP6)
The unmitigated landscape impacts resulting from the ECR
cutting through the pond areas at Lok Ma Chau and Hoo
Hok Wai and grassland at Ma Tso Lung which links the LMC Loop with the
new road to KTN NDA would be as follows:
·
The
proposals would lead to loss of vegetation within the grassland, agricultural fields and lower
vegetated slopes at Ma Tso Lung. There would also be
an impact on the mature tree clusters on
vegetated slopes located to the east of Tse Koo Hang. Some preservation of these tree clusters may be
possible through local fine tuning of the road alignment.
·
Another
key impact would be the extensive loss of marshland and fishponds at Lok Ma Chau and Hoo Hok Wai and the fragmentation of the
landscape character within this area due to
road widening works and construction of depressed road and underpass section of
ECR.
·
This
loss of roadside and woodland trees,
fishponds, marsh, agricultural fields have a moderate adverse impact on the existing landscape resources.
The
landscape impacts resulting from road widening of road widening/ improvement works
of existing Boundary Patrol Road at Ma Tso Lung would be as follows:
·
Moderate Adverse impact on LR3.4 Ma Tso Lung Mixed Woodland, LR7.3 Lok
Ma Chau Agricultural Fields, LR8.4 Lok
Ma Chau Fishponds, LR8.5 Hoo Hok Wai Fishponds, LR9.3 Natural Stream at Lok Ma
Chau Tsuen and Ping Hang, LR11.2 Marsh at Hoo Hok Wai and LR9.4 Natural Stream
at Ma Tso Lung.
·
Slight Adverse impact on LR5.2 Ma Tso Lung Shrubland, LR6.4 Grassland
at Ma Tso Lung and LR12.3 Ma Tso Lung Developed Area and Roads.
SO3 - Western Connection Road (including LMC
Road/San Tin Highway Connection) (DP2)
The
landscape impacts resulting from road widening/improvement works of LMC Road and Ha Wan Tsuen Road would be as follows:
·
The
trees lining the LMC Road fall into two main size ranges with the southern
section forming roadside mass tree planting and the northern section being lined by mature trees (with a DBH larger than
500mm). These trees could be affected by the proposed works. As the road would
be widened to accommodate the predicted traffic and the provision of a cycle
track / footpath and noise barrier there would inevitably be some tree loss.
This would be apparent at the roadside, along sections of the existing central
median and at the lower slopes adjacent to the road junction of LMC Road and
the access road to LMC Tsuen.
·
As
a result of the road modification works, the introduction of sections of noise
barrier and the limitation of land acquisition, the landscape mitigation
measures including tree planting will be limited by spatial constraints.
·
Open
yards and carparking areas and existing roadside corridors along LMC Road, roadside areas at the periphery of Ha Wan
Tsuen and villages along LMC Road will be affected by road widening works
accommodating new footpath and cycle track.
·
The
road widening proposal for Ha Wan Tsuen Road will mainly concentrate on the
western side of the alignment to minimize impacts on the existing landscape
character. Although the road alignment has been adjusted, some of the mature
trees and significant/important trees along the eastern side of Ha Wan
Tsuen Road would be affected. This proposal would also lead to the loss of the
existing trees and vegetation along the western side of Ha Wan Tsuen Road, the
existing slopes, fishpond bunds and the mature trees along the eastern side of
Ha Wan Tsuen Road.
·
Impacts on wooded
slopes to the south of Ha Wan Tsuen and fishponds adjacent to the road. The ruminant slopes (with woodland
trees) will be affected by construction of retaining structures and slope
cutting. This loss of trees and wooded
slopes will have a
moderate adverse impact on the existing landscape resources and the landscape
character of the LMC Lowland Rural Landscape. The existing
manmade (with plantation) slopes
along LMC Road will also be affected by the construction of retaining
structures for road improvement works. This loss of trees and wooded
slopes will have a
moderate adverse impact on the existing landscape resources and the landscape
character of the LMC Lowland Rural Landscape.
·
The open yard
(currently occupied for car parking), developed areas and road surface along
LMC road is subject to a slight impact.
The
landscape impacts resulting from slip road connecting LMC Road to San Tin
Highway would be as follows:
·
The construction
of slip road and road surface reconstruction will utilise existing carriageway
and roadside areas to accommodate the columns and landing as to minimize impacts on the
existing landscape character. Although
the road alignment is largely on top of existing highway structures, the
proposal would lead to a loss of trees in roadside planting areas along San Tin
and Fanling Highways.
·
The realignment of
planned NWNT cycle track from LMC Road roadside areas to the north along an
existing water channel side running parallel to Fanling Highway and Castle Peak
Road will utilise the hard paved areas along the channel and preserved tree
lined along the channel as far as technically feasible to minimise the
landscape impact. Although there would inevitably loss of trees.
·
This
extensive loss of roadside trees will have a moderate adverse impact on
the existing landscape resources and the landscape character of the San Tin Lowland Rural Landscape.
The unmitigated impact as a result of the construction of WCR (DP2) includes the followings:
·
Moderate Adverse impact on LR2.1
Ha Wan Tsuen Village Settlement, LR2.2 Lok Ma Chau Road Village
Settlement, LR3.1 Ha Wan Tsuen Road Mixed Woodland, LR3.2 Lok Ma Chau Road Mixed
Woodland, LR4.1 Roadside Planting along Lung Hau Road, LR4.2 Roadside Planting
along Fanling and San Tin Highways , LR4.3 Roadside Planting along Lok Ma Chau
Road, LR4.4 Roadside Planting along Ha Wan Tsuen Road, , LR8.2 Ha Wan Tsuen Fishponds, , LR8.4 Lok Ma Chau Fishponds, LR9.1 Natural River (to the
South of the Loop) , LR9.2
Natural Stream at Ha Wan Tsuen and LR10.3 Engineered Water Channel (Lok Ma Chau
Road) .
·
Slight Adverse impact on LR1.3 Cross boundary Infrastructure and
Facilities (Lok Ma Chau Bus Terminal),
LR12.1 San Tin Developed Area and Roads, LR12.2 Lok Ma Chau Developed
Area and Roads, LR13.2 Lok Ma Chau Open Yard and LR13.3 Ma Tso Lung Open Yard.
SO4 - Flushing Water Service Reservoir (DP7)
The
construction of Flushing Water
Service Reservoir and access road would lead to loss of tree alongside
of Boundary Patrol Road and grass on the knoll opposite to the HKPF LMC
Operation Base. The proposed works will have a slight
Adverse impact on LR6.4 Grassland at Ma Tso Lung.
SO5 - Direct Link To MTR LMC Station (DP3)
The construction of viaduct and columns along the
alignment form MTR LMC Station to the Loop and the
elevated PTI extending existing station would lead to loss of tree and vegetation within the Station
and its mitigation wetland, LMC BCP and fishponds at Ha Wan Tsuen. The
construction of this direct link will have unmitigated includes the followings:
·
Moderate Adverse on LR4.1 Roadside
Planting along Lung Hau Road , LR8.4 Lok Ma Chau Fishponds, LR9.2 Natural Stream at Ha Wan Tsuen and LR11.5
Mitigation Wetland and Reedbed at MTR LMC Station,
·
Slight Adverse on LR1.1
Cross-boundary Infrastructure and Facilities (MTR LMC Station) ,
LR1.2 Cross-boundary Infrastructure and
Facilities (Lok Ma Chau), LR8.2 Ha Wan
Tsuen Fishponds LR10.2 Engineered Water Channel (along Cross-boundary

11.5.2.2 Predicted Impacts on Existing Landscape Character Areas
Due to
the scale of the LMC Loop Development project, there are some adverse impacts
on the existing landscape characters of the lowland and hillside areas at the
north New Territories from LMC to Ma Tso Lung although sensitive areas such as
Sham Po Shue located to the west of the LMC Station will be spared impact due
to the implementation of the project.
The
sources of impact on the landscape context of the assessment area according to
individual DPs under EIAO Schedule 2 include the following:
SO1 - Development on the Loop (including DP1, DP4, DP5)
Implementation
of development for the LMC Loop, and the associated infrastructure and
utilities facilitating the development and the site formation works. Change of
low intensity lowland rural landscape to a highly developed institutional
landscape.
SO2 - Eastern Connection Road (DP6)
ECR from
Ma Tso Lung to the LMC Loop composed of on-grade, depressed and underpass sections for the road widening works along Boundary Patrol Road and a new section on
grassed area at Ma Tso Lung. There is change of rural character of Ma
Tso Lung and Hoo Hok Wai
rural landscapes.
SO3 - Western Connection Road (including LMC
Road/San Tin Highway Connection) (DP2)
WCR from
the San Tin Highway to the Lok Ma Chau Road and Ha Wan Tsuen Road composed of
mainly road widening/improvement works and the construction of a slip road from LMC Road to San Tin Highway involve a change in the road
corridor and character of LMC and Ki Lun Shan rural landscapes and LMC cross-boundary infrastructure and
facilities landscape .
SO4 - Flushing Water Service Reservoir (DP7)
Flushing
Water Service Reservoir and associated access road at Ping Hang. Introduction
of new semi-sunken reservoir on grassed Horn Hill
will have change on LMC hillside landscape character.
SO5 - Direct Link To MTR LMC Station (DP3)
The Direct Link to the MTR LMC
Station composed of viaduct and new PTI
connecting to the MTR
LMC Station would involve a change on the LMC
cross-boundary infrastructure and facilities landscape.
Table 11.5.7 describes the
source of impacts as a result of the proposed development in the LMC Loop and
its associated infrastructure and presents the magnitude of change for
individual LCAs. Figures 11.5a to 11.5e map the
predicted impacts to the LCAs within the assessment area. The magnitude of
change for individual LCAs as a result of the LMC Loop Development under EIAO
Schedule 3 are also described below:
Large
According to the
assessment result in Table 11.5.7,
the landscape character of individual LCAs including LMC Loop Riverside
Landscape (LCA8) will be largely affected or lost due to site formation works
for the Loop Development and the associated infrastructure and utilities works
on the LMC Loop and so the magnitude of change would be large.
Intermediate
According to the assessment the extent of the perceptible change on landscape character as a result of a result of road widening/improvement works for WCR and ECR, Direct Link to MTR LMC Station and Flushing Water Service Reservoir, and the loss of landscape resources such as lowland rural and hillside landscapes would result in an intermediate magnitude of change. This includes the landscape character of LCAs of LMC Cross-boundary Infrastructure and Facilities Landscape (LCA 2), LMC Lowland Rural Landscape (LCA5), LMC Hillside Landscape (LCA6), and Ma Tso Lung Lowland Rural Landscape (LCA 7).
Small
According to the assessment the extent
of the perceptible change on landscape character as a result of road
widening/improvement works for WCR and ECR, and the loss of landscape resources
such as lowland rural landscape their sensitivity, Ki Lun Shan Lowland Rural
Landscape (LCA4) and Hoo Hok Wai Lowland Rural Landscape (LCA 9) would be subject to a small magnitude of
change owing to the location of the proposed WCR LMC Road to San Tin Highway
Connection and ECR at the edge of the LCA and relatively small extent of the
area affected.
Nil
The following LCAs
have no perceptible change as a result of proposed works, the landscape
character remains unchanged and so the magnitude of change is therefore
negligible. These LCAs include Sam Po Shue Lowland Rural Landscape (LCA1)
and San Tin Lowland Rural Landscape
(LCA3).
The following
section summaries the source of impacts and magnitude of change on landscape character areas as a result of
individual DPs under Schedule 2.

Table 11.5.8 presents the predicted
unmitigated and mitigated (Day 1 and Year 10 / Residual) impacts on the
existing landscape character resulting from the proposed works during the construction
and operational phases of the project. The mitigated (residual) impacts are
assessed during the design year (10 to 15 years after the schemes opening) when
the proposed mitigation planting is deemed to have reached a level of maturity,
which is sufficient for it to perform the design objectives. Significance
thresholds for the unmitigated impacts on landscape character areas for the LMC Loop Development under EIAO
Schedule 3 are
summarised as follows:
Significant Adverse Impact
LCA8 LMC Loop Riverside Landscape – This area is dominated by coarse grassland with a small orchard at the southwest corner of the LMC Loop. The marshes at the south-eastern portion adjacent to the meander have naturally evolved from the abandoned fishponds. With the exception of the banana trees in the orchard, only a few self-seed trees have naturally colonised the site from the adjacent woodland. The large scale and hence magnitude of change arising from the proposed development and associated infrastructure within the LMC Loop will lead to a comprehensive change in the existing landscape character of this LCA. Given the above this LCA will be subject to significant adverse impact due to the construction works and during the operational phase of the project.
Moderate Adverse Impact
LCA2
LMC Cross-boundary Infrastructure and Facilities Landscape –
This LCA covers the areas of MTR LMC Station and its PTI, mitigation wetlands
and reed cell for waste water polishing, LMC BCP and its vehicular waiting area.
The area extends from LMC BCP next to Shenzhen River to San Tin Interchange. As
the PTI of MTR LMC Station and a limited
portion of LMC BCP will be renovated to adopt the column of proposed viaduct
from the Loop to the Station (Direct Link to MTR LMC Station), this would be
inevitably some loss of existing trees and paved landscape areas in this LCA.
Besides there is some road surface reconstruction to accommodate the slip road
from LMC Road to San Tin Highway (WCR), some roadside planting will be affected
by the works.
Given additional planting in these cross-boundary
facilities is not allowed, trees affected by proposed works will be
transplanted or compensated off-site. The loss of mitigation wetland will be
compensated off-site according to ecologist proposal. Given the low sensitivity of this LCA, it would be subject to a moderate adverse
unmitigated impact due to the construction works and during the operational
phase of the project.
LCA4
Ki Lun Shan Lowland Rural Landscape – This LCA covers the areas to the south of San Tin
Interchange and Kwu Tung Road. The area is largely characterised by light
industry and open storage and a large construction site. As existing road
surface will be reconstructed to accommodate the proposed slip road connecting
LMC Road and San Tin Highway, there would inevitably be some loss of roadside
planting along the highway and some alternation of access to properties
adjacent to the road. However the wooded areas within this LCA will remain
unchanged. Given the medium sensitivity of this LCA, it would be subject to a moderate adverse
unmitigated impact due to the construction works and during the operational
phase of the project.
LCA5 LMC Lowland Rural Landscape – This LCA covers the areas alongside the LMC Road, Ha Wan Tsuen Road and the existing Boundary Road; and at another location the proposed LMC Road will pass through this LCA. As LMC Road will be widened to accommodate the predicted traffic and the provision of a cycle track / footpath and introduction of sections of noise barrier there would inevitably be some tree loss. Some of the trees lining LMC Road including a number of mature specimens could be affected by the proposed works although they will be preserved wherever technically feasible through the adoption of mitigation measures outlined below. The loss of trees would be apparent at the roadside, along sections of the existing central median and at the lower slopes adjacent to the road junction of LMC Road and the access road to LMC Tsuen.
In addition, the extent of the
land acquisition and the spatial requirements for the proposed noise barriers
would limit the scope for new tree planting. The proposals would also lead to
the loss of existing trees and vegetation along the western side of Ha Wan
Tsuen Road, the existing slopes, fishpond bunds and the mature trees and significant/important along the eastern side of Ha Wan Tsuen Road. Given the medium sensitivity of this LCA, it would be subject to a moderate adverse
unmitigated impact due to the construction works and during the operational
phase of the project.
LCA6 LMC Hillside Landscape – This area covers the uphill areas of LMC ridges, it
is largely characterised by shrub and grassland with very few trees
interspersed in the shrubland. As the grass knoll located to the south of HKPF
Operation Base will be reformed to accommodate the proposed Flushing Water
Service Reservoir and its access road from Boundary Patrol Road, there would
inevitably be a few loss of trees and
shrub adjacent to Boundary Patrol Road. The proposed
mitigation measures are designed to reinstate the hillside landscape through provision of a new tree and
shrub planting along access road and surrounding the built structures. Given the high sensitivity
of this LCA, it would be subject to a moderate adverse unmitigated impact due
to the construction works and during the operational phase of the project.
LCA7
Ma Tso Lung Lowland Rural Landscape – The
introduction of the proposed Eastern Connection Road would lead to loss of
vegetation within the vegetated hill slopes, grassland
and abandoned agricultural fields at Ma
Tso Lung. There would also be an impact on the mature
tree clusters on vegetated knolls to the east of Tse Koo Hang. Some preservation of tree clusters may be possible through local
fine tuning of the road alignment. The proposed mitigation measures are
designed to reinstate the roadside and rural landscape through provision of a
new roadside landscape area. Given the scale of the proposed road connection
network and the high sensitivity of this LCA, it would be subject to a moderate
adverse unmitigated impact due to the construction works and during the
operational phase of the project.
LCA 9 Hoo Hok Wai Lowland Rural Landscape - The at-grade section of the ECR cuts through two small areas of marshland and fishponds with a correspondingly small impact on the landscape character of the area. Although the landscape features of Hoo Hok Wai are important to the local landscape setting the impacts would be mitigated to an extent through the restoration or re-provision of the wetland habitats required as part of the ecological mitigation and the proposed roadside tree planting. Owing to the high sensitivity of this LCA, the unmitigated impact on this LCA will be moderate during the construction and operational phases of the project.
Slight Adverse Impact
None
of the identified LCAs will be subject to a slight adverse impact in the
construction and operational phases of the project.
Negligible Impact
LCA1 Sam Po Shue Lowland Rural Landscape – As the proposed development and road connection network will be located to the east of this LCA there will be no impacts on landscape elements within it or its landscape character. As such there will be no perceptible change in the amenity of the landscape and the LCA will be subject to a negligible impact.
LCA3 San Tin Lowland Rural Landscape – As the proposed development and road
connection networks will be located away from this LCA, the landscape character
would remain unchanged. Therefore there will be no perceptible change of
amenity and so the LCA will be subject to a negligible impact.

character areas as a result of individual DPs under Schedule 2.

11.5.3 Landscape Mitigation Measures
The landscape
mitigation measures described in this report are at a level which both
demonstrates their ability to alleviate the landscape impacts identified in the
assessment and also to allow the proposals to be carried forward during the
detailed design stage. The measures are designed to address impacts arising
from both the construction and operational phases of the project. More detailed
landscape and compensatory planting proposals will be developed during the
detailed design of this project. During the detailed design a detailed Tree
Survey Report will be prepared separately and submitted for approval by
relevant departments.
The landscape mitigation measures are described both in a generic sense for measures, which apply to all of works area and in terms of the proposed landscape strategy for the proposed permanent works. The aim of the mitigation measures is to:
·
Alleviate
where possible landscape impacts which are unavoidable through the review of
the disposition, alignment, scale and massing of the proposed built structures
for the LMC Loop development and its associated infrastructure.
·
Establish
a coherent and integrated landscape strategy creating a framework which draws
together visually disparate components of the proposed scheme and where possible
reduces its visual prominence and enhances the integration of the structures
within their landscape setting.
·
Enhance
the existing landscape character of the surrounding areas.
·
Provide
a co-ordinated approach between the ecological and landscape mitigation
proposals where there is an interface.
The
Preliminary Landscape Master
Plan and Landscape
Design Concept Drawings for the proposed developments within the LMC Loop, the
associated road connection networks, the WCR and ECR are presented as Figures 11.8, 11.9a to 11.9zi. These drawings
demonstrate the main landscape and visual mitigation strategies and the
application of design mitigation measures including the integrated design
approach, new roadside planting proposals and recreation of marsh. The application
of the recommended mitigation measures is mapped on the plans.
Overall Landscape Concept for the RODP of
the LMC Loop Development
The landscape concept builds on the urban design theme providing integration between the urban intensity of the high-rise development of the SZ skyline with the open rural landscape on the HK side. This is evident in the concept of the two interlocking hands, where the fingers resemble the merging of the landscape and the built environment. This is both symbolic and provides a means of blurring the boundary between the proposed built environment and an open rural landscape characterized by a combination of fish ponds, agricultural areas, small woodland clumps and the slopes of the uplands which enclose the area. This transition is also softened through the use of naturalistic landscape buffer areas including woodland belts, the intermittent woodland and marshland of the Ecological Area in the southern part of the LMC Loop, and the landform and tree planting which screens the Second Boundary Fence to the northwest.
The Landscape Master Plan is illustrated in Figure 11.8. The landscape and open space framework adopts a hierarchy of
Primary, Secondary and Tertiary Open Spaces together with their associated
landscape components. Landscape elevations and perspectives showing the relationship between the different landscape components
and the development are shown in Figure 11.9 a to g. A hierarchical open space network is designed to create spaces with
different levels of intimacy and activities and a thematic approach is adopted
to provide an overall cohesive quality, but also imbuing individual spaces with
a unique character. Landscape design components are discussed in
the following sub sections.
Primary
Open Space
Pedestrian
Promenade
The
Pedestrian Promenade forms a key landscape corridor,
orientated on a northeast-southwest axis connecting the key development clusters in the heart of
the site and providing the primary space for interaction. Although this is a
primary open space the level of intensity of use declines as it nears the
central section where it interfaces with the central Ribbon Park and at either
end where it opens up into a Riverside Plaza. A sectional elevation of the
Pedestrian Promenade is shown in Figure 11.9b. It
responds to the faceted form of the building frontages along the corridor and
provides a flexible series of landscape spaces ranging from Pedestrian
Promenade type landscapes to open flexible spaces. This design intends to
promote human interaction and vibrancy, allows opportunities for people to
gather, and caters for out spill activities brought about by active frontages
at the ground floor of the adjacent buildings.
Ribbon
Park
The Ribbon
Park bisects the Pedestrian Promenade on a northwest-southeast axis. This
park serves as a landscape extensions and accentuates (with the Green
Connectors described below) the green fingers which form the basis of the
integrated urban and landscape design concept. This space also provides a view
corridor creating a linkage between the developed areas and the rural landscape
beyond, aligning with the peaks and ridges of the uplands to the southeast and
the flat agricultural plane to the northeast and southwest. Landscape elevation and perspective of the central portion
of the Ribbon Park are shown in Figure 11.9e to g.
Secondary
Open Space
The second
tier of landscape spaces on a northeast-southwest axis intersect and connect
the three landscape fingers and or Ribbon Parks and provide the landscape
setting for the main building clusters.
Green
Connectors
The Green
Connector spaces are characterised by the irregular enclosure of the enclosing
built form. They will feature tree and shrub planting designed to form
continuity with the primary open spaces to which they link. The Green
Connectors located to the north east and south west adopt a similar design
approach to the Ribbon Park although at a different scale and level of
intensity; and provide for connectivity between the other components of the
open space network including pedestrian
circulation and the
Courtyard Spaces associated with each of the lots.
Woodland
Transitional Zone
The
Woodland Transitional Zone forms an interface between the Ribbon Park and Green
Connectors to the north and the Ecological Area to the south forming a buffer
between the active use areas and the more sensitive ecology of the wetland. It
provides a pedestrian accessible space characterised by naturalistic planting
and an undulating footpath network. A combination of woodland structural
planting and earth mounding allow this zone to accommodate low density, single
storey development, and cycle track and footpath network without disturbing the
ecological value of the wetland to the south. Again this area provides a
combination of landscape buffer extending the landscape fingers concept,
passive open space and ecological resource.
Footbridge
Plaza
The
footbridge, located at the northern periphery of the LMC Loop, provides for the vital
connectivity with SZ. To emphasize the importance of this feature and to provide for visual and physical
connectivity between two areas, a plaza will form
threshold space establishing the character of the LMC Loop at the point of entry. This
plaza is naturalistic in character utilising native tree and shrub species, and
is connected to the
main pedestrian network within the LMC Loop.
Riverside
Platforms
The
Riverside Platforms, located on the south western and north eastern
periphery of the
development, provide
pedestrian and visual access to the Old SZ River
Meander. These spaces take advantage of the landscape
and visual amenity of the less ecologically sensitive part of the river course
and form the end points of the main Pedestrian Promenade. These areas represent
the least kinetic in terms of the level of activity and a tranquil space beside
the river. They are characterised by a combination of a decorative paved area
containing seating and enclosed by a canopy of tree planting.
Tertiary
Open Space
A third
tier of landscape spaces are found at the building level in the form of
internal courtyards or quadrant spaces. These spaces provide more intimate
enclosure with a character reflecting the modernity of the architecture that
embraces them.
Courtyard
Spaces
The third
tier within the landscape hierarchy is provided by the Courtyard or Quadrant
Spaces associated with each of the development plots. These centrally located
spaces respond to the unique form of the buildings which enclose them in terms
of spatial composition, enclosure and open aspect. The Courtyards provide for
the break-out activities from the adjacent buildings and through the use of
visually permeable building envelopes create a connection between interior and
exterior space. The design for each
courtyard spaces will be unique and responds to the modernity of the built
environment. Continuity with the surrounding landscape is provided through the
use of a common hard and soft landscape design palette. Perspectives of typical
courtyard space in the LMC Loop are shown in Figure 11.9e to g.
Podium
Landscapes
An important aspect of the urban design for the LMC Loop is the creation of series of podium structures lining the main Pedestrian Promenade designed to increase the sense of space at the pedestrian level, reduce the abrupt transition between the built environment and its landscape context, and increase visual access to the landscape beyond the Loop. The podium landscapes will perform a similar role to the Courtyard Spaces described above providing scope for out- spill activities from the active frontages of the adjacent buildings. The transition between the podium level and the ground floor landscapes will be softened though the use of vertical greening on the podium edge, and a combination of tree and shrub planting.
Ecological
Area
The Ecological Area, located along the south-eastern boundary of the LMC Loop, forms one of the key ecological design measures. The design of the Ecological Area is driven by the ecological functions to be compensated, as well as, the habitat requirements of the target species. The creation of this area aims to enhance and create areas of reedbed compensating for the habitat loss - one of the most important ecological resources within the area – as well as providing a corridor connecting ecologically important areas to the east and west of the LMC Loop. Owing to the sensitivity of the ecology, this area will be closed to pedestrian movement and protected by the proposed Woodland Transitional Zone which forms a buffer protecting the wetland from disturbance. The landscape of this area will be characterized largely by marshland areas with small areas of naturalistic shrub land and grassland at the periphery. It also serves as a landscape buffer creating a subtle transition between the built development to the north and the landscape of the river corridor and the rural landscape to the south. The marshland has been separated into a number of zones to create a structurally diverse landscape but also to respond to the territorial instincts of the wildlife it will attract.
Parkway
Boulevard
The main
access route through the site is conceived as a Parkway Boulevard, with
generous tree and shrub planting margins integrated with main landscape open
spaces and components beyond. It is designed with extensive roadside planting
integrated with Landscape Buffer design to create a green entrance gateway to
the LMC Loop and establish a unique and strong identity for overall development.
Tree
Avenues
The
internal access routes and connecting spaces between different developments
with the Parkway Boulevard serve as entry and arrival
points to individual building plots. These routes and spaces are designed with avenue trees creating a shaded
user-friendly and pleasant environment to individual developments and open
areas. These tree avenues will be lined with flowering
native and ornamental trees to provide an attractive entry
experience.
Green
Roofs and Vertical Greening
A green
roof system is recommended on roof of buildings and vertical greening for the
building facades where technically feasible to provide a third dimension of
greening framework to the LMC Loop. The roofs will also provide opportunities
for additional landscaped areas potentially open to the students and staff of
each building block.
These
measures soften the architectural form of the proposed buildings, enhance the
landscape integration of the proposed structures particularly in elevated views
and enhance the integration of the proposed built environment within its rural
context. They will also realize significant environmental benefits both in
terms of reducing the heat loading of each building and addressing the
potential heat island effect of the hard architectural and landscape surfaces.
11.5.3.1 Primary Mitigation Measures
In
accordance with the TM-EIAO, the hierarchy for landscape impact mitigation is
first avoidance of impact, then minimisation of impact and finally compensation
of impact. The current proposals have been designed to fulfil the following
objectives:
·
With reference to
Section 11.5.2, Avoidance/Minimisation of impacts on landscape resources such as existing trees by
review of the alignment for proposed road connections and the disposition of
built components.
·
Restoration
and enhancement of existing landscapes through the planting large sized trees
(semi-mature and heavy standard) at key locations following the completion of
the construction phase of the project, which will create an instant greening
effect on the site.
·
Review
of the work sites and areas to ensure that sufficient space is reserved within
the facilities for compensatory planting and other landscape works.
·
In
accordance with the TM-EIAO, mitigation measures for the construction and
operational phases of the project have been designed to minimize predicted
landscape and visual impacts, and to compensate for the loss of landscape
resources given the Project constraints.
11.5.3.2 Secondary Mitigation Measures
A series
of mitigation measures designed to alleviate impact and where possible
compensate for the loss of landscape resources, change of landscape character
and visual amenity for VSRs resulting from the construction and operational
phases of the project. The implementation, funding, and management and
maintenance for the amenity landscape areas associated with the
proposed works will be undertaken by project proponent and/or relevant
departments. The proposed landscape mitigation measures are summarized in Tables 11.5.9 and 11.5.10.
11.5.4 Construction Phase
The
proposed landscape impact mitigation measures in the construction
phase are summarized in Table 11.5.9
Table 11.5.9 Proposed construction phase mitigation measures
Mitigation Code |
Mitigation Measure |
CP1 |
Preservation and
Protection of Existing Trees (Good Site Practice) · The proposed works should avoid disturbance to the existing trees within and close to the works areas. The tree preservation proposals shall be coordinated with the layout and design of the engineering and architectural works at detailed design stage for further retention of individual trees. · It is recommended that a full detailed tree survey and felling application will be undertaken and submitted for approval by the relevant government departments in accordance with ETWB TCW No. 3/2006, ‘Tree Preservation’. This will be conducted during the detailed design stage of the project and submitted to DLO for approval. The methodology and scope including the programme for the tree survey and felling application are also subject to the approval of the relevant authorities. · Trees which are not in conflict with the proposals would be retained and shall be protected by means of fencing during construction stage to prevent damage to tree canopies and root zones from vehicles and storage of materials. · Specifications for the protection of existing trees will be provided during the preparation of the detailed tree survey by Detailed Design consultants at detailed design and construction stage. |
CP2 |
Works Area and Temporary Works Areas (Good Site Practice) · The construction sequence and construction programme shall be optimized in order to minimize the duration of impact. · Construction site controls shall be enforced including the storage of materials, the location and appearance of site accommodation and site storage; and the careful design of site lighting to prevent light spillage. · The temporary works areas shall be restored to its original condition or enhanced through the introduction of new amenity areas or planting areas following the completion of the construction phase. |
CP3 |
Advance
Implementation of Mitigation
Planting ·
Replanting of existing / disturbed
vegetation shall be undertaken at the earliest possible stage of the construction
phase of the project using predominantly native plant species although
ornamental species may be used for roadside planting and amenity areas. |
CP4 |
Transplantation of Existing Trees · Some specimens have relatively higher amenity value which are in conflict with the proposals shall be considered for transplantation. For trees affected by the proposed infrastructure works the final receptor sites shall be preferably adjacent to their current locations alongside of the alignment to retain their contribution to the local landscape context. For the LMC Loop the receptor locations will be selected to allow the trees to be moved directly to their final locations in accordance with the detailed landscape proposals. · The transplanting proposals are subject to review at the detailed design stage and to agreement-in-principle with the relevant management and maintenance agents and/or government departments. The implementation programme for the proposed works shall reserve sufficient time for the advanced tree transplanting preparation works to enhance the survival of the transplanted trees. · The transplanting proposals will be subject to the findings of the detailed tree survey and felling application to be undertaken by the detailed design consultants and following approval by the relevant departments. |
CP5 |
Coordination with Concurrent Projects · Coordinated implementation programme with concurrent projects to minimise impacts and where possible reduce the period of disturbance. |
CP6 |
Creation of Wetland
and Landscape Buffer ·
The existing reedbed acquired for
development areas for the project will be reinstated as part of the
Ecological Area. The reinstatement shall be undertaken at the earliest
possible stage during the construction phase of the project. ·
Creation of 12.78ha
of Ecological Area (EA) containing reed marsh and marsh will be
created at the southern portion of the LMC Loop, and a 50m width landscape
buffer area will be set up in between the EA and the development area.
Wetland creation concepts please refer to Figure 11.9zf
and Chapter 12 Ecology Imapact Assessment of this EIA. ·
Native tree and shrub mix will be
utilised for the creation of landscape buffer along northern edge of EA to support
the creation of avifauna habitat from ecologist perspectives as well as
enhance the aesthetic and landscape diversity within the LMC Loop
Development. ·
Creation of minimum 11.72 Ha. of
permanent compensatory off-site wetland areas at Sam Po Shue and Hoo Hok Wai.
For the potential locations for off-site wetlands please refer to Figure 11.9zf and 11.9zh, Chapter 2
Project Description and Chapter 12 Ecology Impact Assessment of this
EIA. |
CP7 |
Design of Retaining Wall and Slopes ·
The proposed treatment of Retaining Wall
and Slopes will be undertaken in accordance with GEO Publication No. 1/2011
"Technical Guidelines on Landscape Treatment and Bio-engineering for
Slopes". These engineering structures will be aesthetically enhanced
through the use of soft landscape works including tree and shrub planting to
give man-made slopes a more natural appearance blending into the local rural
landscape. Whip sized tree planting is
preferred on the face of soil cut slopes and at the crest and toe of the
slope, and within berm planters. The smaller, younger plant stock will adapt
to their new growing conditions more quickly than larger sized stock and
establish a naturalistic effect more rapidly. Hydroseeding will be applied on slope has a gradient more than 30 degree. |
11.5.5 Operational Phase
The
proposed landscape impact mitigation measures in the operational phase are
summarized in Table 11.5.10.
Table 11.5.10 Proposed operational phase mitigation measures
Mitigation
Code |
Mitigation
Measure |
OP1 |
Roadside and Amenity Planting ·
The planting proposals will utilise both native and ornamental species which suitable for roadside planting to
soften the built structures and enhance visual amenity of existing and
proposed road corridors. The implementation of new planting
shall be undertaken as soon as technically feasible using a sectional
completion approach during construction stage to ensure the effectiveness of
this mitigation during operational stage and as early as possible during the
operational phase. |
OP2 |
Compensatory Planting Proposals ·
As the works are largely located
within rural areas and alongside existing roads the planting proposals have
sought to utilise all of the available space for new tree and shrub planting to
create comprehensive landscape framework which is connected to areas of
retained and preserved vegetation and designed to integrate the proposals
within their future landscape setting.
·
The planting proposals shall be
maintained in accordance with good horticultural practice in order to realise
the objectives of the mitigation measures. This includes the replacement of
defective plant species on the new planting areas to enhance the aesthetic,
landscape and ecological quality of the proposals. ·
Both on-site
and off-site opportunities for compensatory planting shall be considered. ·
The preliminary compensatory planting
proposal will follow the Technical Circular ETWB TCW No. 3/2006 except for
felling of trees for slope works which are exempted from the compensation
planting ratio requirement. New tree planting in general roadside planting areas and planting
areas within the LMC Loop and above
ground structures will
utilise a combination of semi-mature to light standard sized stock as shown in Figures 11.9a and 11.9h to 11.9zi to
create an instant greening effect at local level. ·
New planting areas within the LMC Loop including tree planting in
the landscape buffers, open spaces and roadside planting areas will accommodate
approximately 5,000
new trees. Planting of more broad-leaf
tree species will be considered where space allows and location is suitable
for tree establishment. This planting concept would create comfortable shaded
area for pedestrians and visitors in open spaces. ·
New planting areas along the road alignment of WCR (DP2), ECR (DP6) and access road to
Flushing Water Service Reservoir (DP7) will
accommodate approximately 2,600 new trees. ·
For the affected tree on the sloping
areas, due to constrained growing
conditions, whip planting will be proposed on slopes which have gentler
gradient at a planting distance of about 1500mm. Slopes that have a gradient more than 30
degree, hydroseeding will be applied instead. Upon full establishment of whip
planting and hydroseeding, greening coverage on affected sloping areas will
be reinstated. Following the above planting principles, the newly formed and
remnant sloping areas along the road
alignment
would accommodate approximately 500
whips. ·
Based on a preliminary estimation, the
above planting proposal would achieve a replanting ratio of minimum 1:1 in
terms of quantity and quality except for slope works according to ETWB TCW
No. 3/2006. This tree replanting ratio would compensate the total girth and
number of tree loss as well as the total number of tree loss on sloping area.
Given the constraints of growing condition and safety reasons of planting
larger size tree stock on sloping areas, greening measures on new formed and
remnant slopes, including extensive hydroseeding and whips planting, would
restore the quality of these greenback drop in rural
area. ·
The species selection for planting areas within the LMC Loop will
utilise a range of native, ornamental
and amenity tree species.
These proposals will be subject to further development during the detailed design
stage of the project.. ·
Proposed planting on slopes will utilise woodland mix with
majority of native species on new or
disturbed slopes along the WCR and ECR. |
OP6 |
Creation of Woodland ·
1.1 Ha. of woodland areas will be created
off-site as ecological mitigation measures for the loss of woodland. The
creation of a woodland compensation area will involve planting of woodland
and shrubland species in grassland areas currently of low ecological value
along the existing Boundary Patrol Road near Horn Hill at Ping Hang. For details of the off-site
woodland compensation please refer
to Figure 11.9zi,
Chapter 2 Project Description
and Chapter 12 Ecology
Impact Assessment
of this EIA. ·
In addition
to the above, disturbed wooded slopes along WCR (DP2) and ECR (DP6) by the
road widening and improvement works will be infilled with woodland planting
of light standard size trees or whips where space allows to restore and
enhance the ecological and landscape value of the remnant woodland areas. |
OP7 |
Reinstatement
of Affected Fishponds ·
Enhancement
of 11.72 Ha. of wetland/fishponds
at Sham Po Shue and Hoo Hok Wai with ecological function for the off-site compensation of the permanent loss of fishponds. Off-site fishponds enhancement proposal refer to Figure 11.9zh, Chapter 2 Project
description and Chapter 12 Ecology Impact
Assessment of this EIA. ·
Temporary
loss of fishponds along WCR (DP2), Direct Link
to LMC Station (DP4) and ECR (DP6) by the road widening and improvement works
will be largely reinstated to
fishponds with
tree planting at selected locations.
Reinstatement of affected fishponds refer to Figure 11.9j,k,l,m,r, t and u. These ponds
will be used for both functional or amenity purposes to enhance the existing landscape and visual context. |
OP8 |
Application
of Terraced Podium Landscape, Vertical Greening and Green Roof · Terraced podium design shall be incorporated into the building design of the LMC Loop Development to maximise the greening opportunities on upper level of the development, reduce the apparent visual mass of the structure and provide visual amenity for views looking from street level as well as in distance at elevated levels as to create better integration with existing landscape and visual context. · Incorporation of alternative greening measures including vertical and roof greening on building or built structures where condition allow particularly those fronting the public realm to reduce the apparent visual mass of the structure. |
11.6 Visual Baseline, Impact Assessment and Mitigation
11.6.1 Visual Baseline
11.6.1.1 Existing Visual Context and Visual Envelope
The
visual envelope (VE) is the area within HKSAR from which the proposed
development will be seen, and is shaped by a combination of the existing
adjacent built development, the landform of the surrounding area and in some
locations existing vegetation. It extends from the summits of the LMC ridge
line (overall height below +120mPD) to Tai Shek Mo in the south, Hoo Hok Wai in
the east and Sam Po Shue in the west with visibility extending inland through
the valleys which bisect the upland areas including that at LMC and the Ng Tung
River valleys.
There
are panoramic views across the flat expanse of the fishponds towards the LMC Loop (i.e. Area A) with its
pockets of trees and shrub and tall grass / reed growth. The villagers in lowland settlements located
in the areas proximate to Area A form the main VSRs including those living in
Ha Wan Tsuen, Ha Wan Fishermen Village, LMC Tsuen, Tai Law Hau, Ping
Hang and Tse Koo Hang alongside Ha Wan Tsuen Road and existing Boundary Patrol
Road and some villagers in San Tin, Chau Tau and Ma Tso Lung. There are two
aspects to the views available to many of these VSRs. At lower levels VSRs will
have glimpsed views of the proposed development because the majority of
low-level views to the LMC Loop are interrupted and obstructed by the
intervening topography and/or vegetation. For some VSRs more elevated views
extend towards the upper part of the future development on Area A.
An
important consideration in the design of the proposals is respect for the
ridgeline from LMC to Tai Shek Mo which will form the backdrop to views of the
future LMC Loop and serve to screen views available to the future residents of
the proposed KTN NDA.
The VE
for the proposed ECR is formed by two main components. To the west of the
alignment the VE extends across the flat expanse of the existing fishponds
north towards Hoo Hok Wai and south west along the corridor formed by the
fishponds adjacent to Ping Hang and Tai Law Hau. The alignment will also be
visible from the uplands to the south and south east particularly the hills
between Ping Hang and Ma Tso Lung. The second component of the VE lies within
the agricultural valley of Ma Tso Lung San Tsuen and Shun Yee San Tsuen. In this second area there will be largely
open views across the valley floor although there will be some partial
screening due to intervening trees and small woodland clumps. At a more
elevated level views extend from the valley sides to the east and west of the
alignment although these views are available to few VSRs.
The VE
for the proposed Flushing Water Service Reservoir is
similar to the western part of the ECR alignment extending north across the
existing fishponds at Hoo Hok Wai and south west along the corridor formed by
the fishponds adjacent to Ping Hang and Tai Law Hau. Owing to its higher
elevation views of the reservoir also extend north west and west to the area of
the LMC Loop.
Owing to
the locations of the VSRs and the nature of the existing view which is shaped
by the existing topography and/or vegetation, the main visual mitigation will
come from the preservation of the existing landform and vegetation, the overall
layout, the scale and disposition of the proposed built environment; and the
integration of significant landscape features within the proposed development
and the surrounding landscape context.
The alignment
of the proposed WCR will follow the route of the existing LMC Road which
bisects the agricultural plane at the western base of the uplands which form
the setting for the Loop. The WCR will be located within a landscape enclosed
by existing features such as the San Sham Road, the LMC Cross-boundary facilities; and the LMC Spur
Line to the west; and the development associated with the villages of Chau Tau,
Pun Yuk Tsuen, and Ha Wan Fishermen Village to the east of the alignment. In addition the existing road
corridor is lined by intermittent mature tree planting with views also being
partially obscured by vegetation within the agricultural fields and at the edge
of the existing village settlements.
The VE
for the proposed viaduct for the Direct Link to MTR LMC
Station extends south to the viaduct structure of the LMC Spur Line and the
vegetation at the periphery of Ha Wan Tsuen whilst views to the north will extend to the banks of the
Shenzhen River and beyond to locations such as the footbridge for the LMC
Cross-boundary Facilities. Framed and partially obscured views will also extend west
from the future development on the western periphery of the LMC Loop.
In
addition to the permanent VSRs described above, vehicle travellers on the LMC
and Ha Wan Tsuen Roads, train passengers on the Spur Line and visitors and
staff at the boundary crossing facilities, will have partial views of the
proposed development on Area A and more open views of the upper portions of the
proposed buildings and structures. Visual mitigation for these transient VSRs
will come from a combination of the design of the scheme proposals and the
integration of proposed development within its local landscape context.
The
extent of the visual envelope and the zones of visual influence are presented
in Figures 11.6a
to 11.6g and
photographs showing the views available to each of the VSRs are presented as Figures 11.6h to 11.6s.
11.6.1.2 Visually Sensitive Receivers
VSRs are
identified as those groups or individuals, who have a view of the proposed
developments based on the preliminary assumptions discussed in the previous
sections, are sensitive and will be subject to adverse impacts as
a result of the development. The sensitivity of a particular VSR is influenced
by location (sensitivity tends to decrease with distance from the proposed
scheme), direction and nature of the view relative to the scheme (an open and
full views will be more sensitive than a partial of glimpsed view), and VSR
type. The number of individual receivers represented by VSR will also affect
its sensitivity.
The
principal VSRs within the assessment area are the residents of developments and
villagers in lowland settlements who might have views to the proposed
development, vehicle travellers, visitors and staff of the boundary crossing, rail and other infrastructural facilities whom have a view
of the proposed development.
The
selected VSRs are representative of the views available to people surrounding
the proposals and include the following:
·
VSR1: Residents of Lin Barn Tsuen Village
Settlement;
·

The
following section provides a description of the views available to each of the
identified VSRs and should be read in conjunction with the photographs
presented as Figures 11.6h to 11.6s Visually
Sensitive Receiver Photographs.
VSR 1 Residents of Lin Barn Tsuen Village Settlement
These
VSRs have a relatively long distance view looking northeast towards the LMC
Loop at a distance of approximately 2250m (Figure 11.6h
refers). They enjoy low-level panoramic views across the Sam Po Shue fishponds
which are partially interrupted by the existing LMC Cross-boundary infrastructural facilities and the Spur Line in the background and
largely screened by adjacent in the foreground on fishpond areas. To the north the distant views are
dominated by the high-rise urban setting of Shenzhen. These VSRs are few in number and their visual
quality is fair. Given a combination of the nature and long distance of
existing views; their visual quality, disrupted visibility and that only the
higher levels of the proposed buildings on the LMC Loop may be seen by these
VSRs, their sensitivity is medium.
VSR 2 Residents of Tung Chan Wai Village Settlement
Only the
villagers living at the northeast periphery of Tung Chan Wai at San Tin will
have partial views towards the proposed development at the northern portion of
the LMC Loop at a distance of 1400m. (Figure 11.6h
refers). Given their low building height profile, the visual context of these
VSRs is largely contained by other village development at San Tin to the south
and open storage immediately to the east. Similar to VSR1, the LMC Cross-boundary infrastructural facilities and the Spur Line are apparent in the
middle ground to the east and form a major visual intrusion within the
available views. These VSRs are few in
number and their visual quality is fair. Given a combination of their
nature and visual quality, the disrupted visibility and the relatively long
viewing distance; and that only the higher levels of the proposed buildings
within the LMC Loop will be visible may be seen by these VSRs, their
sensitivity is medium.
VSR 3 Travellers and Staffs at LMC Cross-boundary Bus Terminal
The
views available to travellers and staff from the bus terminal are at a
relatively low-level and largely confined by roadside trees, the
structures associated with the adjacent roads and highway and open storage (Figure 11.6h
refers). These VSRs may have glimpsed views of WCR at a distance of 150m to the
east, although this is dependent on the nature of the works in each area and overview of road surface reconstruction to
accommodate the LMC Road and San Tin Highway Connection formed part of the WCR.
The number of VSRs is
large but the views are transient in nature. Their visual quality considered to
be poor being dominated by the surrounding infrastructural landscape. Although
these VSRs may be in close proximity to the proposed works at LMC Road and San Tin Highway, given the nature and containment of the
available views their sensitivity is low.
VSR
4 Vehicle Travellers along Fanling and San Tin
Highways
Similar
to VSR 3, views available to vehicle travellers on the Fanling and San Tin Highways are
transient and interrupted and confined by adjacent highway structures (Figure 11.6h
refers). Views extending towards the village settlements in the hinterland are
largely screened by mature roadside vegetation. These VSRs are large in number
and their visual quality is poor. Despite these VSRs being in close proximity
to the proposed works at LMC Road and slip
road connecting to San Tin Highway, given the nature of the views and their containment within the
infrastructure corridor, their sensitivity is low.
VSR 5 Vehicle Travellers and Pedestrians along LMC Road
Views
available to vehicle travellers and pedestrians are transient in nature and
largely confined within the road corridor by the adjacent car parks, open storage, village houses and mature
roadside tree planting along LMC Road and Ha Wan Tsuen Road (Figures 11.6h to i
refer). Views extending west towards the proposed development are interrupted
by the structures associated with the LMC Cross-boundary
facilities and the Spur Line. These VSRs are intermediate in number and their
visual quality ranges from poor at the southern portion and relatively better
at the northern portion when approaching Ha Wan Village and the LMC Loop.
Despite being in relatively close proximity to the proposed works at LMC Road,
and being able to perceive the proposed developments at the LMC Loop when
moving towards Ha Wan Tsuen, the disturbed nature of the views and their visual
containment within the road corridor results in their sensitivity being low.
VSR 6 Residents of Ha Wan Tsuen Village Settlement
Although
Ha Wan Tsuen is located at a distance of 150m immediately to the west of the
LMC Loop, the mature vegetation at the entrance square of the village and along
Ha Wan Tsuen Road screens most of the low-level views of the LMC Loop (Figures 11.6i to j refer). However
any proposed buildings on the LMC Loop with a higher building height profile
than the adjacent village houses may lead to changes in the visual context.
Existing alternate views to the west of these VSRs are interrupted by the
structures associated with the LMC Cross-boundary
facilities and the Spur Line in the middle ground and are occasionally screened
by mature vegetation on the fishpond bunds and tree planting along the Spur
Line. Longer distance views to the north are dominated by the high-rise
development of Shenzhen. These VSRs
will also has partial views of proposed at-grade works along Ha Wan Tsuen Road
and largely screened by existing mature trees at the eastern entrance of Ha Wan
Tsuen. These VSRs are
small in number and their visual quality contained within the village environs
is fair. Given a combination of their permanent nature; quality of their
disrupted and confined visual context and their proximity to the proposed works
in both the LMC Loop and associated supporting infrastructure outside the LMC Loop, their sensitivity is high.
VSR 7 Residents of LMC Village Settlement
These
VSRs, located to the east of Ha Wan Tsuen, have panoramic views across the
fishpond areas to the north and the LMC Loop in the middle ground at a distance
of 150m with the high-rise development of Shenzhen forming the background (Figure 11.6j
refers). Views looking to the south are dominated by mixed woodland at the
lower hill slopes emanating from the ridges extending from west to east. These
VSRs are small in number and their visual quality is fair. Given their nature
and extent of views available and their proximity to the LMC Loop, their
sensitivity is high.
VSR 8A Residents of Pun Uk Tsuen Village Settlement
These
VSRs are located at a distance of 250m to the east of LMC Road (Figure 11.6j
refers). The majority of the views looking towards the LMC Loop are screened by
the intervening landform. Low-level views looking to the west and the north are dominated by mixed woodland at the lower hill slopes
of the LMC ridges. Views to the south are characterised by abandoned agricultural fields in the foreground and trees along Chau Tau West Road and LMC Road in the background, views to LMC Road have been largely screened. View east
to Fanling Highway have been blocked by intervening land form, trees and Pun Uk
Tsuen. The number of
VSRs is small and their visual quality is fair. Given nature of available views and the disrupted
viewshed caused by intervening landform, trees and built environment, their distance and extent of views of the proposed works, their sensitivity is medium.
VSR 8B Residents of Chau Tau Village Settlement
These
VSRs are located at a distance of 250m to the east of LMC Road (Figure 11.6j
refers). The majority of the views looking towards the LMC Loop are screened by
the intervening landform. Low-level views looking to the north
are dominated by mixed woodland at the lower hill slopes of the LMC ridges.
Views to the south are characterised by active agricultural fields, stormdrain pumping stations
and retention ponds and trees along Chau Tau South Road. The number
of VSRs is small and their visual quality is fair. Views to the west are screened by trees along Chau Tau West Road. Views
looking toward the proposed WCR are screened by mature roadside trees and built
environment. Given nature of available views and the disrupted
viewshed caused by intervening landform, trees and built environment, their distance and extent of views of the proposed works, their sensitivity is medium.
VSR 9 Residents of Tai Law Hau Village Settlement
Residents
of this village with a view of the proposals are located at a distance of
approximately 150m immediately to the south of the LMC Loop with views across the
abandoned meander and fishponds areas along the existing Boundary Road (Figure 11.6k
refers). They have panoramic views of the wide expanse of the LMC Loop with the
high-rise urban setting of Shenzhen in the background. Although due to the
relatively low elevation of the viewing position the screening effects of the
intervening vegetation particularly tree planting is apparent. These VSRs are
few in number and their visual quality is fair. Given the extent and nature of
views available and their proximity to the LMC Loop, their sensitivity is high.
VSR 10 Residents of Ping Hang Village Settlement
Located
some 150m immediately to the south of the LMC Loop these VSRs enjoy views
across the abandoned meander and fishponds areas along the existing Boundary
Road (Figure 11.6k
refers). Similar to VSR9, they have panoramic views of the LMC Loop with the
high-rise urban setting of Shenzhen in the background which are interrupted by
intervening vegetation particularly trees. Close and open views look towards at-grade ECR works along Boundary
Patrol Road is available from these VSRs. These VSRs are few in number and their visual
quality is fair. Given the extent and nature of views available and their
proximity to the LMC Loop, their sensitivity is high.
PVSR 10A Planned Visitors to the Eco-lodge
This
planned development will be located on the lower, northern hill slopes of Ma
Tso Lung at a distance of less than 100m from the proposed ECR and
approximately 400m from the LMC Loop (Figures 11.6k and r refer). The views
available to the north facing accommodation will be both elevated and panoramic
extending over a landscape of agricultural fields and fishponds to the
abandoned meander the LMC Loop with the high-rise urban setting of Shenzhen in
the background. The programme for the implementation of the Eco-lodge proposals
is unknown at this stage. These planned
VSRs will be relatively few in number and their visual quality will be fair.
Given the extent and nature of views available and their proximity to the LMC
Loop, their sensitivity is high.
VSR 11 Travellers and Staffs at LMC Cross-boundary Infrastructure Facilities
Given
the configuration of the cross-boundary facilities, the views available
to travellers and staff are transient and largely confined within the custom
areas with occasional glimpsed views along the Shenzhen River corridor through
the windows of the footbridge which crosses the river (Figure 11.6l
refers). These VSRs have elevated views of proposed development on the LMC Loop
at a distance of approximately 1100m whilst
have an immediate view of proposed viaduct from MTR LMC Station to the LMC
Loop. The number of
VSRs is large and the quality of their view is fair. Given the nature and
extent of views available, their sensitivity is low.
VSR 12 Train Travellers on LMC Spur Line
Train
travellers on the Spur Line enjoy both panoramic views of the lowland areas of
the NWNT with its mountain backdrop and the high-rise urban setting on the
other side of Shenzhen River (Figures 11.6i and l refer). These
transient VSRs have an easterly elevated view of the LMC Loop at a distance
ranging from 300 to 1000m. These VSRs will also have open views of proposed
direct link to MTR LMC Station as proposed viaduct alignment is running in
parallel to the Spur Line. The number of VSRs is relatively large and the quality of their view is
fair. Given the nature and extent of views available, their sensitivity is
low.
VSR 13 Residents of Tse Koo Hang Village Settlement
The
relatively small numbers of VSRs at Tse Koo
Hang located to the south of the
Hoo Hok Wai fishpond area contained
by woodland at the lower eastern slope of LMC Ridges are living in single storey village houses (Figure 11.6l
refers). Views from VSRs located in the northern
portion of the village is contained by adjacent woodland and will have a close
view of the proposed works for ECR along
Boundary Patrol Road. View looking towards the LMC Loop is obstructed by
adjacent woodland. Views from VSRs at the southern portion of the villages have
an open view of grassland and agricultural fields in the foreground and
overview of Ma Tso Lung Tsuen and Shun Yee San Tsuen and uphill Tai Shek Mo in
the background. These VSRs will have an overview of the section of ECR located
in the grassland. The
number of VSRs is very few; quality of
main view is good and
given their nature and extent of views available, their sensitivity is high.
VSR 14 Residents of Liu Pok Village Settlement
Liu Pok Village
is located to the north of Tai Shek Mo. The majority of the villagers enjoy
views of Ng Tung River and Lo Wu Cross-boundary
Facilities in the middle ground with the high-rise urban setting of Shenzhen
beyond (Figure 11.6m
refers). The low level views are largely screened by the vegetation at the
lower slopes of Tai Shek Mo which also serves to frame views towards the
fishponds in the foreground to the north. Only villagers living at the western
periphery of the village have partially obstructed views looking towards the
Hoo Hok Wai lowland areas. Views
looking towards the
proposed development on the LMC Loop and road
works at Ma Tso Lung are largely obscured by intervening uphill topography of
Tai Shek Mo and vegetation in the settlement. The
number of these VSRs is small and their visual quality is fair due to
surrounding vegetation and partially enclosed topography. Given the nature and
extent of views available, their sensitivity is high.
VSR 15 Travellers on Planned Boundary Patrol Road to the East of LMC Loop
Based on
current operation of the Boundary Patrol Road, the new road along the
northern periphery of the LMC Loop will also be utilised by both the Hong Kong Police Force as well as maintenance departments and villagers and operators with closed area
permits for the access of Hoo Hok Wai fishponds areas (Figure 11.6m
refers). These transient VSRs will enjoy views of the Shenzhen River and its
riverside areas through the boundary fence alongside the road. Their visual
context extends to the lowland rural landscape through a secondary boundary fence newly constructed within the HKSARs territory to the
south which forms the foreground, the lower slopes of the LMC ridge in the
middle ground and high-rise urban setting of Shenzhen to the north. These VSRs
may have an immediate view of the LMC Loop through a secondary boundary fence newly constructed, and a more distant view of the
associated infrastructure facilities outside
LMC Loop at a distance of 150m across the Hoo Hok Wai fishpond areas. The number
of these VSRs is very small and their visual quality is
fair due to the intrusion of the fence structure. Given the nature, extent and
quality of their views, their sensitivity is medium.
VSR 16 Travellers on Planned Boundary Patrol Road to the West of LMC Loop
As with
VSR15 these VSRs enjoy partially obstructed views to the riverside areas. Views
from the west looking towards the LMC Loop are currently dominated by the LMC
Cross-boundary facilities and the structures associated
with the Spur Line (Figure 11.6n
refers). With the integration of the building height profile and building
design of proposed LMC Loop development with these existing medium-rise
infrastructure facilities, the
proposed Direct Link to MTR LMC Station, a new viaduct aligned with the Spur
Line, and at-grade WCR crossing the river surrounding the LMC Loop, the cumulative effect on the
existing visual quality of the lowland area would not be significant. Given the
nature, extent and the quality of their views is fair, their sensitivity is medium.
VSR 17 Travellers and Staffs at Lo Wu Cross-boundary Infrastructure Facilities
Similar
to VSR11, views of these transient VSRs are largely confined within the customs
area, with occasional glimpsed views of the areas along the Shenzhen River
corridor through the windows of the river footbridge (Figure 11.6n refers).
Views west from these VSRs towards the LMC Loop and
associated infrastructure outside LMC Loop at a distance of 2500m are largely obscured by the intervening landform of Tai Shek Mo.
The number of VSRs is large and the quality of their view is fair. Given the
nature and extent of views available, their sensitivity is low.
VSR18 Residents of Shun Yee San Tsuen
Shun Yee
San Tsuen is located to the east of the LMC Loop at a distance over 1200mm.
These VSRs have a relatively long distance view looking towards the northwest
to the LMC Loop with extensive Hoo Hok Wai fishpond areas in the foreground (Figure 11.6n
refers). Views are partially interrupted by the existing intervening landform
of Ma Tso Lung and LMC Ridges. Alternative views from these VSRs extend to the
south across the grassland and agriculture fields at Ma Tso Lung in their foreground and lower slope of LMC Ridges in the
background. Given these VSRs located at a higher elevation, they will have an
open view of proposed at grade sections of ECR. They are few in number and
their visual quality is fair. Given the nature of the available view, its
visual quality, disrupted visibility and the relatively long distance it is
predicted that only the upper portions of the proposed buildings on the LMC
Loop and ECR will be visible to these VSRs and so their sensitivity is medium.
VSR19 Residents of Ha Wan Fishermen Village Settlement
These
VSRs are located to the south of LMC Tsuen, and their views are largely contained inside the village due to
surrounding landform of the lower slopes of LMC ridges and mixed woodland (Figure 11.6o
refers). The views towards the LMC Loop will be obstructed by intervening landform and topography and surrounding woodland. Regarding
to their proximity to the works along LMC Road for the proposed WCR, these VSRs
will have glimpsed views toward the WCR through dense vegetation at the edge of
village. VSRs are
small in number and their visual quality is fair. Given the nature and extent
of views available to the LMC Loop, their sensitivity is medium.
VSR20 Public Users of LMC Lookout
These VSRs, located at a higher elevation on slope to the south of LMC Tsuen, enjoy panoramic views across the fishpond areas, shrubland, LMC Tsuen and the LMC Loop to the north and mixed woodland at lower slopes of LMC ridges in the foreground (Figure 11.6o refers). The viewing location for this VSR is taken as the area adjacent to the Lok Ma Chau Police Station which is publicly accessible and has open views north towards the LMC Loop whilst views from the lookout towards the LMC Loop is partially obstructed by trees surrounding the lookout. From this location VSRs will have views of the construction works and completed development at the LMC Loop, road works at Ha Wan Tsuen Road and Direct Link to MTR LMC Station (viaduct). These VSRs are small in number and their visual quality is fair. Given the nature and extent of views available to the LMC Loop and associated infrastructures outside the Loop, their sensitivity is medium.
VSR 21 Residents of Ma Tso Lung Village Settlement
The main views of these VSRs are confined within the
valley surrounding by LMC ridge and Tai Shek Mo. Majority views towards the
grassland and agriculture fields from the village are obstructed by intervening
village houses and planting in the fields, only the VSRs located at the north-western periphery will have an open view of the
grassland and fields. Relatively long distance views
for these VSRs looking northwest towards the LMC Loop, these views are largely
obstructed by intervening landform of LMC ridge and vegetation. (Figure 11.6p
refers). Given the VSRs at north-western portion of the settlement enjoy views
across the agricultural fields and grassland, these VSRs will have views full
or partial views of the proposed ECR.
These VSRs are small in number and their visual quality is fair. Given
the nature and extent of views available to the LMC Loop, their sensitivity is
medium.
VSR 22 Travellers on the Existing Boundary Patrol Road at Ma Tso Lung
Travellers
on the existing Boundary Patrol Road currently enjoy views to the southwest through existing boundary fence towards the agricultural land
around the settlement of Ping Hang and its setting of wooded hill slopes
leading to the LMC ridge; and an open view of Hoo Hok Wai.
The existing closed area
boundary fence in the
foreground degrades the quality of the existing view (Figure 11.6p
refers). Views of the proposed development will be immediate with the proposals
for the ECR with its associated structures and more distant views towards the
southern periphery of the development within the LMC Loop. These VSRs are
relatively few in number. Given a combination of the visual amenity available
to VSRs at this location and the impact of existing infrastructure the
sensitivity of these views is medium.
VSR 23 Vehicle Travellers and Pedestrians along Ha Wan Tsuen Road
The view
north for these VSRs at a distance of approximately 600m extends along Ha Wan
Tsuen Road towards the LMC Loops is characterised by a combination of the
existing, remnant fishponds and to the west the infrastructural development
associated with the LMC Spur Line (Figures 11.6p and q
refer). Partially interrupted views
north east will be restricted to the upper portion of the proposed developments
within the Loop with the lower elevations being screened by the intervening
vegetation. There will also be immediate views of the proposed road widening
works along Ha Wan Tsuen Road. These VSRs are relatively few in number. Given
the disturbed nature of the existing view the sensitivity of this VSR is low.
VSR 24 Residents along Lok Ma Chau Road
Views
available to residents in the properties lining Lok Ma Chau Road are largely
contained within the road corridor although there are partially interrupted
views east towards the uplands of the LMC ridge line (Figure 11.6q refers). Owing to the orientation of
the village houses the views for many of the residents extend away from the
proposed development. With the development of the proposals views will be
immediate extending to the road widening works for Lok Ma Chau Road and in a
number of locations will be partially blocked by the construction of the non-continuous noise barrier
ranging in height from 0.8 to 5m. The number of VSRs will be small in number
and given a combination of the nature of the existing views and the orientation
of many of the village houses, fair quality of their main views, the sensitivity of these views
is considered to be low.
VSR 25 Workers of Workshops and Container Storage along Kwu Tung Road West
The views available to workers within this location are largely screened by the existing container storage and workshop structures within the area and the intervening structures associated with the San Tin Interchange (Figure 11.6q refers). Although views of the main development within the LMC Loop are unlikely due to the screening effect of the intervening landform and development there will be immediate views towards the proposed road connection from LMC Road to San Tin / Fanling Highways. The number of VSRs in this location is small, and their quality of view is poor. Given a combination of the nature of existing view with its existing highway structures and the limited extent of available views the sensitivity is low.
VSR 26 Staffs of HKPF Lok Ma Chau Operation Base
These
VSRs are located at a distance of approximately 700m immediately to the east of
the LMC Loop with views across the abandoned meander and fishponds areas along
the existing Boundary Patrol Road (Figures 11.6r
and s refer).
Views from within the helicopter base facility are restricted to the upper levels
of development at LMC
Loop. Views from the entrance to the facility are panoramic extending to the LMC Loop with
the high-rise urban setting of Shenzhen in the background. There will also be
immediate views from this location towards the Eastern Connection Road. These
VSRs are few in number and their visual quality is fair. Given the extent and
nature of views available and their proximity to the proposals, their
sensitivity is medium.
The
sensitivity of the identified VSRs to further change ranges from high to low
due with the value and quality of existing views, visibility of the proposals
due to the restrictions caused by intervening local topography, built
environment and vegetation including mature trees. The VSRs are represented by
both transient or permanent receivers and their populations range from large to
small. Table 11.6.1
describes the sensitivity of the selected VSRs within the ZVI, the quality of
their existing views and their ability to accommodate change.

11.6.2 Visual Impact Assessment
The LMC Loop Development project is a designated
project (DP) under Environmental Impact Assessment Ordinance (EIAO) with
Schedule 3 Item 1 - Engineering feasibility study of urban development
projects.
With reference to Section 2.3.4.1 and Figure
2.1a of the EIA Report the LMC Loop Development is composed of proposed
uses of higher education, high-tech R&D and C&C industries. This LVIA is based on the proposed
development parameters and project components listed the Chapter 2 Project
Description and Section 11.5.2 of this LVIA. Key project components related to
visual impact assessment are summarized in the following sub sections:
·
The RODP shown on Figure 2.1b has
incorporated a more dynamic height profile with gradation in building heights
for the LMC Loop in response to the general environment of the area. Existing
level of the LMC Loop is currently relatively flat at a level of +4.5 to
+6.0mPD and the proposed site formation
levels at about +5.90mPD.
·
Creation of 12.8 ha Ecological
Area (EA) to south of LMC Loop to enhance both ecological and landscape context
as well as maintain visual amenity of the riverside landscape.
·
Creation of 50m wide landscape buffer
zones between the Shenzhen River in the
north and the Ecological
Area in the south to the proposed development.
Besides, other 20 to 30m wide landscape areas are reserved along the eastern and western periphery of
the LMC Loop. These landscape buffers will soften the low level views of
proposed development on the LMC Loop.
·
Responsive
plot ratio and building height profiles with regards to the adjacent infrastructure and rural landscape
characters. Within the
framework of 1.2Mm2 GFA, the overall plot ratio will be 1.37. The
building height profile was formulated with regard to the
public comments and amenity/activity corridor. The low-rise building will be
placed at the south and east of LMC Loop to minimize the impact to flight lines
and EA. Tallest buildings will be located at the western and
central part of LMC Loop, where ecological sensitivity is relatively less. The
tallest buildings will be approximately 12 storeys from ground level (about
54mPD). It serves as a primary gateway for the site. Building
heights along the Shenzhen River would be of lower rise and gradually rise towards the centre of the site and again gradually
decrease towards the southern boundary of the site. Furthermore, the
building height of the commercial sites near Hoo Hok Wai has been reduced
to minimize the impacts of the proposed buildings on
the birds’ flight paths. These
stepped building height profiles will create a better integration with the
rural landscape setting within HKSAR boundary and high-rise urbanized setting
in Shenzhen in the north across the river.
·
Flushing
Water Service Reservoir at Horn Hill: There is a need to maintain adequate head for flushing water supply. In order to save pumping energy
for individual buildings, the flushing water service reservoir would be
located at Horn Hill, which is the highest hill near LMC Loop. The selected location is selected and exposed to
less VSRs identified.
·
Sewage
Treatment Works (STW) for treatment of sewage arising from
the development of LMC Loop is sited at southeast corner of LMC Loop where is the optimum location on site to handle sewage. The buildings of sewage treatment works will be low rise and there will be minor human
activities. Thus it has benefits on minimizing the visual impact.
·
Creation of ecological Area and landscaped open
space and amenity areas, greening provision on podium, building façade and roof
would make the development on the LMC Loop a better integration with
surrounding rural context. It should be
noted the urbanised and high-rise context at Shenzhen to the north of LMC Loop
have been formed the background of the proposed development. The impact on the landscape character of the
LMC Loop has been hence largely reduced against this urbanised background.
·
There are some
associated infrastructure and utilities works proposed outside the LMC Loop.
Given to the scale of these works, impacts on the rural and hillside landscape
characters to the south of the LMC Loop is not significant.. The responsive
selection of road alignment and location of reservoir follows largely existing
Boundary Patrol Road and on grassed Horn Hill that would significantly reduce
the impacts on landscape resources and hence the visual context Hoo Hok Wai and
LMC hillside landscape. The use of depressed and underpass road connection from
Hoo Hok Wai to the LMC Loop will further reduce the visual intrusion of engineering
structures in lowland fishpond areas. The Direct Link To the MTR LMC Station is
designed in form of viaduct aligned with existing Spur Line that would have a
better integration with existing character of the cross-boundary facilities at
LMC.
In addition to the key visual issues as a result of
the LMC Loop Development under Schedule 3 mentioned above, refer to Section 2.4
and Figure
2.1a to 2.26c
of the EIA Report, Section 11.5.2 of this LVIA, the following key visual issues
associated infrastructures proposed within or outside the LMC Loop of
individual Designated
Projects (DPs) under Environmental Impact Assessment Ordinance (EIAO) Schedule
2, are summarized.
Ecological Area (DP1)
·
Ecological Area (EA)
located at the southern portion of the LMC Loop for the creation of reed bed
along the meander and the replacement of wetlands within the LMC Loop to
enhance the visual quality and character of LMC riverside landscape.
Western Connection Road (DP2)
·
The works area of
road widening/improvement works has been fine tuned to maximise the
preservation of mature trees along Lok Ma Chau Road and Ha Wan Tsuen Road to
maintain visual quality of rural areas.
Direct Link to MTR LMC Station (DP3)
·
The alignment of this
railway connection largely follows the alignment of existing Spur Line when
approaching MTR LMC Station to create a better visual integration with existing
infrastructure landscape and less intrusive to existing rural landscape. An
elevated PTI will be built on top of existing PTI at ground floor of LMC
Station extending from existing LMC Station. The introduction of viaduct and
elevated PTI will be visually integrated with the existing Spur Line, LMC
Station and surrounding cross-boundary facilities.
Drainage System under Internal Transport Networks (DP4)
·
Integrated
utilities and proposed road networks approach to minimise the visual intrusion
of above ground built structures.
Sewage Treatment Works (DP5)
·
The on-site STW is designed with low-rise buildings and structures, and within
utilization of screw pumps hence to minimize visual impact.
Eastern Connection Road (DP6)
·
The proposed road largely utilises the existing Boundary
Patrol Road with
road widening/improvement works that will minmise the extent of works and
change of existing visual context. Besides, depressed and underpass roads are
designed for the section at Hoo Hok Wai and LMC fishpond to minimize the impact
on landscape resources, existing riverside and lowland landscape characters and
visual context instead of using at-grade road.
Flushing Water Service Reservoir (DP7)
·
The proposed location
of this reservoir
on Horn Hill which is a grassed knoll and less sensitive to
development than woodland. The proposed half-sunken reservoir structures
responds to the topography of the hill and to sited away from VSRs thus
minimize the visual intrusion of engineering structures in the hillside
landscape.
The assessment findings will inform the
future detailed development proposals within the LMC Loop and the design of its
associated infrastructure and utility development options. The conceptual
development proposals will be formulated through an iterative design process,
further refined and developed to accommodate the future institutional design
requirements, and to minimise the predicted residual landscape impacts. As the
development proposals may be further refined the assessment assumes the worst
case scenario in terms of the impacts.
The DPs are
described in Chapter 1 and 2 of the EIA Report. Other non-DP components were
also assessed. The level of details of the DPs is subject to further refinement
at detailed design stage and is provided to the best knowledge available for
the purpose of the assessment
A Visual Impact Assessment has been undertaken to define the visual impacts
associated with as a whole the proposed
development within the LMC Loop, and the associated infrastructure and
utilities facilitating the development including the proposed ECR, WCR, Direct
Link to MTR LMC Station and the Flushing Water Service
Reservoir. The impacts are discussed
specifically in terms of the visual impacts on
the existing VSRs within HKSAR boundary. Mitigation measures have been identified for all proposals and their
effectiveness explored. The acceptability of the development options will
derive from the scale of residual impacts and the ability of the proposals to
mitigate them to acceptable levels.
The assessment findings will provide
information on the future development proposals within
the LMC Loop subject to detailed
design of its associated infrastructure and utilities facilities at the next
stage. The conceptual development proposals shown in
this EIA is indicative and will
be formulated through an iterative design process, further refined and
developed to accommodate the future institutional design requirements, and to
minimise the predicted residual visual impacts. The assessment assumes the
worst case scenario in terms of the predicted impacts.
11.6.3 Construction Phase and Operational Phase
In addition to the landscape resources and
character, the visual amenity of the LMC Loop will be significantly changed due
to the implementation of the proposed developments and the road connection
networks. The visual context and amenity available to the residents of Ha Wan
Tsuen and LMC Tsuen and travellers and staffs, users of MTR LMC
Station and its adjacent Boundary Patrol Road, Ha Wan Tsuen Road and visitors
to LMC Lookout, located in close proximity to the LMC Loop Development (including DP1, DP4 and DP5), the WCR (DP2) and Direct Link
to MTR LMC Station (viaduct) (DP3), will be subject to
a moderate to significant adverse impact.
Other villagers living in Ha Wan Fishermen Village, Chau Tau, Pun Uk Tsuen and houses along LMC Road, travellers and pedestrians of LMC Road, Fanling and San Tin Highways, and LMC cross-boundary bus terminus, and workers of workshops and container storage along Kwu Tung Road West, who are located close proximity to LMC Road and the proposed WCR (including road works with noise barrier and LMC Road/San Tin Connection) (DP2) but located at a greater distance from the proposed development on the LMC Loop, will experience a slight to moderate adverse impact.
The visual context and amenity available to villagers of Ma Tso Lung (Tse Koo Hang and Shun Yee Sun Tsuen), Tai Law Hau and Ping Hang, staffs of HKPF Operation Base and planned visitors to the Eco-lodge who are located along existing Boundary Patrol Road and Ma Tso Lung Road, located to the southeast of the Loop and in close proximity to the ECR (at-grade/depressed/underpass road) (DP6) and/or proposed Flushing Water Service Reservoir (DP7) at Horn Hill, will experience a moderate adverse impact.
Given the long distance from the proposed works, villagers in San Tin who located over 1000m from the proposed works and travellers on the Spur Line, transient in nature, will experience a slight adverse impact. These impacts are also mitigated to an extent due to the screening provided by the intervening topography and the vegetation at the edge of the settlement.
The visual impacts on identified VSRs resulting from the LMC Loop Development under EIAO Schedule 3 during the construction and operational phases are summarised in the following sections and described in Table 11.6.2 and mapped on Figures 11.7a to 11.7g. The mitigated (residual) impacts are assessed during the design year which for the purpose of this study is taken as being between 10 and 15 years after the schemes opening when the proposed mitigation planting is deemed to have reached a level of maturity, which is sufficient for it to perform the design objectives. Significance thresholds for the unmitigated impacts are summarised as follows:
Significant Adverse Impact
Due to the scale of the proposed scheme
there are some significant adverse impacts on the visual amenity of some VSRs
due to the introduction of the proposed developments on the LMC Loop
(including DP1, DP4 and DP5), Flushing
Water Service Reservoir (DP7), viaduct of
Direct Link to LMC Station (DP3) and at-grade sections
of the proposed ECR (DP6) and WCR
(DP2), the 800mm to 5000mm high noise barriers along the proposed Western Connection Road and the
other associated infrastructures. These VSRs will be subject to a large change
of visual context and amenity which include the Residents of Ha Wan Tsuen
Village Settlement (VSR 6); Residents of LMC Village Settlement (VSR 7);
Residents of Tai Law Hau Village Settlement (VSR 9); Residents of Ping Hang
Village Settlement (VSR 10); Planned Visitors to the Eco-lodge (PVSR 10A);
Travellers on Planned Boundary Patrol Road to the East of LMC Loop (VSR 15);
and Public Users of LMC Lookout (VSR 20).
Moderate Adverse Impact
Travellers and Staffs at Lo Ma Chau
Cross-boundary Bus Terminal (VSR 3); Vehicle Travellers along Fanling and San
Tin Highways (VSR 4); Vehicle Travellers and Pedestrians along LMC Road (VSR
5); Travellers and Staffs at LMC
Cross-boundary Infrastructure Facilities (VSR 11); Residents of Tse Hoo Hang Settlement (VSR 13); Travellers on Planned
Boundary Patrol Road to the West of LMC Loop (VSR 16); Residents of Shun Yee San Tsuen (VSR 18); Residents of Ma Tso Lung
Village Settlement (VSR 21); Travellers on Existing Boundary Patrol Road at Ma
Tso Lung (VSR 22); Vehicle Travellers and Pedestrian along Ha Wan Tsuen Road
(VSR 23); Resident along Lok Ma Chau Road (VSR 24); and Staffs of HKPF Lok Ma
Chau Operation Base (VSR 26) will be subject to moderate adverse impacts on
their available visual amenity. Therefore the permanent / transient VSRs listed
above will experience a moderate adverse impact in the absence of mitigation
measures during construction and operation phase. However, much of the
predicted impacts will be mitigated through the implementation of the proposed
landscape and visual mitigation measures.
Slight Adverse Impact
VSRs such as the Residents of Lin Barn Tsuen Village Settlement (VSR 1); Residents of Tung Chan Wai Village Settlement (VSR 2); Train Travellers on LMC Spur Line (VSR 12); Residents of Ha Wan Fishermen Village Settlement (VSR 19); and Workers of Workshops and Container Storage along Kwu Tung Road West (VSR 25) will be subject to a slight adverse impact. This is due to factors such as the viewing distance or the partially obstructed / oblique nature of views to the proposed development or road connection networks. Given the character of the views and viewing distance involved, the proposed developments and infrastructures will not form a major component in the wider context of the views available to these VSRs. The magnitude of change for their visual amenity is small. These permanent VSRs will experience a slight impact in the absence of mitigation measures during construction and operation phase.
Negligible Impact
The following VSRs would be subject to a negligible level of impact during the construction and operational phases of the project due to the screening effect of the intervening landform and vegetation in relation to the height profile of the development proposals. These include the Residents of Pun Uk TsuenVillage Settlement (VSR 8A); Residents of Chau Tau Village Settlement (VSR 8B); Residents of Liu Pok Village Settlement (VSR 14) and Travellers and Staffs at Lo Wu Cross-boundary Infrastructure Facilities (VSR 17).

11.6.4 Visual Mitigation Measures
The visual mitigation measures described in
this report are at a level which both demonstrates their ability to alleviate
the visual impacts identified in the assessment and also to allow the
proposals to be carried forward during the detailed design stage. The measures
are designed to address both the construction and operational phases of the
project. Similar to the principle behind the design of the landscape visual
mitigation measures mentioned in Section
11.5, the hierarchy for visual impact mitigation is classified as the
primary and secondary mitigation measures.
The
Preliminary Landscape Master
Plan and Landscape
Design Concept Drawings for the proposed developments within the LMC Loop, the
associated road connection networks, the WCR and ECR are presented as Figures 11.8, 11.9a to 11.9zi. These drawings
demonstrate the main landscape and visual mitigation strategies and the
application of design mitigation measures including the integrated design
approach, new roadside planting proposals and recreation of marsh. The
application of the recommended mitigation measures is mapped on the plans. Description of Overall Landscape Concept for
the RODP of the LMC Loop Development is under
section 11.5.3 Landscape Mitigation Measures of this LVIA
These
measures soften the architectural form of the proposed buildings, enhance the
landscape integration of the proposed structures particularly in elevated views
and enhance the integration of the proposed built environment within its rural
context. They will also realize significant environmental benefits both in
terms of reducing the heat loading of each building and addressing the
potential heat island effect of the hard architectural and landscape surfaces.
11.6.5
Construction Phase
The
proposed visual impact mitigation measures in the construction
phase are summarised in Table 11.6.3.
Table 11.6.3 Proposed construction phase mitigation measures
Mitigation Code |
Mitigation Measure |
|
CP1 |
Preservation and
Protection of Existing Trees (Good Site Practice) · The proposed works should avoid disturbance to the existing trees within and close to the works areas. The tree preservation proposals shall be coordinated with the layout and design of the engineering and architectural works at detailed design stage for further retention of individual trees. · The preservation of existing tree shall provide instant greening and screening effect for proposed works. |
|
CP2 |
Works Area and Temporary Works Areas (Good Site Practice) · The construction sequence and construction programme shall be optimized in order to minimize the duration of impact. · Construction site controls shall be enforced including the storage of materials, the location and appearance of site accommodation and site storage; and the careful design of site lighting to prevent light spillage. · Hoarding designed with recessive colour shall be set up around the construction site providing screening effect for the construction works. · The site office or temporary above-ground structures shall be sited at less visual prominent locations. |
|
CP3 |
Advance
Implementation of Mitigation Planting ·
Replanting
of existing / disturbed vegetation shall be undertaken at the earliest
possible stage of the construction phase of the project using predominantly
native plant species although ornamental species may be used for roadside
planting and amenity areas. |
|
CP5 |
Coordination with Concurrent Projects ·
Coordinated implementation programme with concurrent projects to minimise
impacts and where possible reduce the period of disturbance. |
|
CP6 |
Creation of Wetland and Landscape Buffer ·
The
creation of EA and landscape buffer on the Loop shall provide screening
effect for low level views towards the LMC Loop Development from the lowland
plain surrounding the lMC Loop and soften the building mass and create a
better visual integration with existing landscape context. |
|
CP7 |
Design of Retaining Wall and Slopes ·
The proposed treatment of Retaining Wall and Slopes will be
undertaken in accordance with GEO Publication No. 1/2000 "Technical
Guidelines on Landscape Treatment and Bio-engineering for Man-made Slopes and
Retaining Walls". These engineering structures will be aesthetically
enhanced through the use of soft landscape works including tree and shrub
planting to give man-made slopes a more natural appearance blending into the
local rural landscape. Whip sized tree
planting is preferred on the face of soil cut slopes and at the crest and toe
of the slope, and within berm planters. The smaller, younger plant stock will
adapt to their new growing conditions more quickly than larger sized stock
and establish a naturalistic effect more rapidly. Hydroseeding will be applied on slope
has a gradient more than 30 degree. |
11.6.6 Operational Phase
The proposed visual impact mitigation measures in the operational phase are summarised in Table
11.6.4.
Table 11.6.4 Proposed
operational phase mitigation measures
Mitigation Measure |
|
OP1 |
Roadside
and Amenity Planting ·
The planting proposals will utilise
native species to soften the proposed structures. The implementation of new planting
shall be undertaken as soon as technically feasible using a sectional
completion approach during construction stage to ensure the effectiveness of
this mitigation during operational stage and as early as possible during the
operational phase. This
measure will enhance the visual amenity along existing and proposed road
corridor. |
OP2 |
Compensatory
Planting Proposals ·
As the works are largely located
within rural areas and alongside existing roads the planting proposals have
sought to utilise all of the available space for new tree and shrub planting
to create comprehensive landscape framework which is connected to areas of
retained and preserved vegetation and designed to integrate the proposals
within their future landscape setting.
·
Both on-site
and off-site opportunities for compensatory planting shall be considered for
enchantment of landscape and visual context. ·
Design of
road layout and built environment shall accommodate enough planting areas for
compensatory planting to restore
the quality of these greenback drop in rural
area. |
OP3 |
Responsive Design of Buildings and Structure · The design of the proposed building structures and road connections networks will incorporate design features as part of visual mitigation measures including: Integrated Design
Approach · Building massing - the proposed use of a responsive design for the disposition of the main elements of the proposed scheme including the locations of buildings and utility structures. Grouping of utilities and infrastructure components into proposed buildings as far as technically feasible to reduce the mass of development. The disposition and height profile of the developments and above ground utilities structures responds to the existing context, is designed to minimise the wall effects and create a subtle transition at the edges of the site where it meets the rural landscape. Measures may include the creation of setbacks, articulating the development frontage, maintenance of view corridors and the utilisation of gradation or articulated height profile to enhance the sense of visual integration with the existing context, avoid abrupt transitions between the existing and proposed built environment and reduce the apparent visual mass of the proposed developments. Treatment of Built Structures · The architectural design should seek to reduce the apparent visual mass of the structures further through the use of materials and finishes such as colour blocking, innovative surface treatments and vertical greening. Responsive finishes for the Proposed Structures · In terms of the building finishes natural tones should be considered for the colour palette and non-reflective finishes recommended for the outward facing building facades to reduce the glare effect. Innovative Architectural
Design · Adoption of recessive colours for the buildings and engineered structures including the proposed viaducts and noise barrier finishes and colour blocking to reduce the collective visual mass of the development. |
OP4 |
Design of
Noise Mitigation Structures ·
The design for the proposed noise barriers along the at-grade
section of proposed ECR
section for
Planned Eco-lodge at Ma Tso Lung and along the
section of road widening works for the WCR shall aim to reduce the visual
prominence of the structure through the use of form, materials, texture and
colour. Design
of penals shall be opaque and with chromatic colours to break-up the visual mass and horizontal emphasis of the
barriers. Where space
allows barrier design shall incorporate planting such as trees or hedge planting. |
OP5 |
Design of Engineering Structures The design of the proposed Engineering Structures such as the proposed viaducts elevated PTI, slip road and service reservoir should pay particular attention to the appearance and construction methods of the structures, these would include the following: · The detailed design landscape consultants shall work in unison with the engineers on the aesthetic aspects of the structures and their relationship with the landscape. · Wherever light levels, the water regime and the requirements of the environmental mitigation measures permit, trees and vegetation would be reinstated below or adjacent to the structures. Irrigation may be required in some locations and hard landscape solutions considered where the clearance is low. Planting would be used wherever possible to minimise the apparent height of structures and to soften their appearance in medium and long distance views. · The design of the viaduct should avoid unnecessary visual clutter; this would be achieved through the co-ordination of the various engineering disciplines involved to arrive at integrated design solutions. Such as the location of columns of viaduct should not block any views from VSRs in the proximity and the shape of column should be slim down as far as technically feasible to reduce the structural mass at street level, at where space is allowed planting area for shade tolerant tree, shrub and climber species would be provide at the base of the column to soften the vertical emphasis at street level. · Fair faced concrete would not be used for viaduct parapets to minimise glare from the structure and to avoid the visually detracting effect of staining. · Drainage and utilities to be concealed within the structures. |
OP6 |
Creation
of Woodland ·
Creation of
woodland
along the existing Boundary Patrol Road near Horn Hill at Ping Hang will
enhance the local landscape and visual context. Off-site woodland compensation
refers to Figure
11.9zi,
Chapters 2 project description and 12 ecology impact assessment of this EIA. ·
In addition
to the above, disturbed wooded slopes along WCR (DP2) and ECR (DP6) by the
road widening and improvement works will be infilled with woodland planting
of light standard size trees or whips where space allows to restore and
enhance the landscape and visual context along LMC Road. |
OP7 |
Reinstatement
of Affected Fishponds ·
Temporary loss of fishponds along WCR (DP2), Direct Link
to LMC Station (DP4) and ECR (DP6) by the road widening and improvement works
will be largely reinstated to fishponds with tree
planting at selected locations.
Reinstatement of affected fishponds refer to Figure 11.9j,k,l,m,r, t and u.
These ponds will be used for both functional or amenity purposes to enhance the
existing landscape and visual context. |
OP8 |
Application of Terraced Podium Landscape,
Vertical Greening and Green Roof · Terraced podium design shall be incorporated into the building design of the LMC Loop Development to maximise the greening opportunities on upper level of the development, reduce the apparent visual mass of the structure and provide visual amenity for views looking from street level as well as in distance at elevated levels as to create better integration with existing landscape and visual context. · Incorporation of alternative greening measures including vertical and roof greening on building or built structures where condition allow particularly those fronting the public realm to reduce the apparent visual mass of the structure. |
This section reviews the projects currently
in progress or planned within the assessment area, such as the proposed cycle
tracks in the North West New Territories and North East New Territories, new
development areas in the North East New Territories and the construction of the
secondary boundary fence and new sections of primary boundary fence and
Boundary Patrol Road. Construction of these projects will result in cumulative
landscape and visual impacts including the degradation of landscape character
and visual amenity and the loss of landscape resources.
The construction works for the Secondary
Boundary Fence and new sections of Primary Boundary Fence and Boundary Patrol
Road under the project entitled ‘Construction of a Secondary Boundary Fence and
new sections of Primary Boundary Fence and Boundary Patrol Road’ are taking
place concurrently and the works sites involved are in the vicinity of the
proposed developments of LMC Loop. In addition, the proposed cycle tracks
connecting the North West New Territories with North East New Territories (Lok
Ma Chau section) under the project entitled ‘Cycle Tracks connecting North West
New Territories with North East New Territories’ will be take place adjacent to
the proposed WCR. There is as yet no
firm programme for the completion of these projects.
Mitigation measures to address the
cumulative impacts would be incorporated into the design of each of the
approved projects. The resulting changes to the existing landscape character,
landscape resources and visual amenity have been taken into account in the
baseline assessment. Cumulative impacts from these projects are therefore taken
into account through their inclusion in the baseline conditions for this report
although as mentioned above at the time of writing there is uncertainty in
terms of the programme for these projects.
11.8
Residual Landscape Impacts
11.8.1
Evaluation of Residual Impact - General
Overall, in terms of residual landscape impacts the
main effects will primarily result from the disturbance to the existing rural
landscape context in LMC Loop, some woodland areas, existing roadside trees
etc. For the most part, the landscape resources will be largely reinstated. The
riverside landscape area of the LMC Loop will be changed significantly as a
result of proposed development. Whilst the current unmanaged piece of land and
rural landscape character on the LMC Loop will be replaced by the
implementation of institutional development and the creation of high quality
landscaped open spaces associated with the development, it will be integrated
with the existing rural and riverside landscape characters along Shenzhen River
after the full establishment of the recommended mitigation measures:
·
Adoption of a responsive scale and
building height profile integrated with local rural context;
·
Integration as far as technically feasible
new built structures with existing rural landscape;
·
Provision of planting areas within the LMC
Loop;
·
Reinstatement of temporary works areas and recreation of
marsh/ wetland and;
·
Incorporation of terraced landscape podium
design, vertical greening and green roof on built structures where technically
feasible; and
·
New tree planting proposals combined with
the preserved trees alongside the proposed ECR , WCR, within the site for
Direct Link to MTR LMC Station and Flushing Water Service Reservoir;
·
Utilised depressed road and underpass,
viaduct and slip road to minimise the impact on landscape resources;
·
Deck over the road section when
approaching to natural stream;
·
Minimise the extent of slope cutting and
retaining wall to minimise the impact on woodland areas and reinstate the
disturded areas with new woodland planting;
·
Reintate fishponds as early as possible;
and
·
Creation of woodland;
The planting proposals also form part of
compensatory planting proposals for the loss of landscape resources, such as
existing trees; and benefiting the future landscape and ecological context of
the assessment area.

Slight Beneficial Impact
Despite
a large amount of self-seeded weedy trees being lost with the development of
the LMC Loop proposals this will be mitigated through the planting of new woodland
and ornamental tree planting throughout the
development area, particular in the proposed woodland buffer area along the
northern edge of the LMC Loop. Therefore LR’s such as the Trees on the Loop (LR4A) would be subject to a slight beneficial
impact as the trees mature.

11.8.3
Residual Impact on Landscape Character
Areas
With the implementation of the recommended
landscape mitigation measures the mitigated (residual) impact for the
individual LCAs as a result of the implementation of the LMC Loop Development
under EIAO Schedule 3 assessed in Table
11.5.8 can be summarised as
follows.
Slight Adverse Impacts
The significant unmitigated impact on the character of LMC Loop Riverside Landscape (LCA 8) will be alleviated to moderate (Day 1 construction and operation) to slight adverse impact (Year 10). This will be evident through the growth to maturity of the proposed landscape mitigation measures, including the establishment of planting proposals and creation of wetland area (EA) on the LMC Loop.
Negligible Impacts
The moderate impact on the character of LMC
Cross-boundary Infrastructure and Facilities Landscape (LCA 2), Ki Lun Shan
Lowland Rural Landscape (LCA 4), LMC Lowland Rural Landscape (LCA5), LMC
Hillside Landscape (LCA 6), Ma Tso Lung
Lowland Rural Landscape (LCA7) and Hoo Hok Wai Lowland Rural Landscape (LCA 9) will be
alleviated to slight adverse during the construction and operation phases (Day
1) of the project whilst the residual impact during operation phase (Year 10)
of the project will be further reduced to a negligible level through the growth to maturity of
the proposed landscape mitigation measures, including
replanting for woodland, stream and channel side and roadside planting areas,
off-site compensation of fishponds and marshes, and reinstatement of fishponds.
The negligible impact of Sam Po Shue Lowland Rural Landscape (LCA 1), San Tin
Lowland Rural Landscape (LCA 3) and would remain unchanged during operation
phase (Year 10) of the Project.
The following
section summarizes the residual impacts on landscape character areas as a
result of individual DPs under Schedule 2.
SO1 - Development on the Loop (including DP1,
DP4, DP5)
The residual
impacts for the construction of Ecological Area (DP1)
Drainage System under Internal Transport Networks (DP4) and Sewage Treatment
Works (DP5) on the LMC Loop includes the followings:
·
The moderate residual impact (Day 1
construction and operation) on the character of LMC Loop Riverside Landscape
(LCA 8) would be alleviated to slight adverse impact (Year 10) through the
growth to maturity of the proposed landscape mitigation measures, including the
establishment of planting proposals and creation of wetland area (EA) on the
LMC Loop.
SO2 - Eastern Connection Road (DP6)
· The slight residual impact (Day 1 construction and operation) on the character of LMC Lowland Rural Landscape (LCA5) and LMC Hillside Landscape (LCA 6), Ma Tso Lung Lowland Rural Landscape (LCA 7) and Hoo Hok Wai Lowland Rural Landscape (LCA 9) would be alleviated to negligible (Year 10) through the growth to maturity of planting proposals.
SO3 - Western Connection Road (including LMC
Road/San Tin Highway Connection) (DP2)
· The slight residual impact (Day 1 construction and operation) on the character of LMC Cross-boundary Infrastructure and Facilities Landscape (LCA2), Ki Lun Shan Lowland Rural Landscape (LCA 4) and LMC Lowland Rural Landscape ( LCA5) would be alleviated to negligible (Year 10) through the growth to maturity of planting proposals.
SO4 - Flushing Water Service Reservoir (DP7)
· The slight residual impact (Day 1 construction and operation) on the character of LMC Hillside Landscape (LCA 6) would be alleviated to negligible (Year 10) through the growth to maturity of planting proposals.
SO5 - Direct Link To MTR LMC Station (DP3)
·
The slight residual impact (Day 1
construction and operation) on the character of LMC Cross-boundary
Infrastructure and Facilities Landscape (LCA2) would be alleviated to
negligible (Year 10) through the growth to maturity of planting proposals and
design of the built structures responded and integrated with existing
infrastructure landscape.
With the adoption
of the recommended visual mitigation measures the mitigated (residual) impact
as a result of the implementation of LMC Loop Development under Schedule 3 for
individual VSRs assessed in Table 11.6.2
can be summarised as follows.
Slight Adverse
The visual amenity of Residents of Ha Wan
Tsuen Village Settlement (VSR 6) and Residents of LMC Village Settlement (VSR
7), Residents of Tai Law Hau Village Settlement
(VSR 9), Residents of Ping Hang
Village Settlement (VSR 10), and Planned
Visitors to the Eco-lodge (PVSR 10A), Travellers on
Planned Boundary Patrol Road to the East of LMC Loop (VSR 15)
and Public Users of LMC Lookout (VSR 20)
will be changed significantly through the implementation
of proposed institutional developments associated with infrastructure and utilities facilities on the LMC Loop, WCR road works and noise
barriers along Ha Wan Tsuen Road and LMC Road, the Direct Link to MTR LMC Station (viaduct) and ECR. The impact of these visual intrusions will be alleviated to an
extent through the limited works areas, responsive design of institutional
development, road alignment and viaduct, noise barrier structures, the use of
vertical greening measures where possible on built structures and the
restoration of the disturbed areas with roadside planting. Although these
measures will not screen views of the proposed development and viaduct
structures, these mitigation measures will soften the form of the buildings and
structures, create a greater sense of visual integration and enhance the
overall landscape of the LMC Loop area, LMC Road, Ha Wan Tsuen Road and existing Boundary Patrol Road at Ma
Tso Lung. With the adoption of these measures, the
significant impact to the visual amenity of these VSRs will be mitigated to
moderate during operation phase (Day 1) and slight adverse during operation
phase (Year 10).
Negligible
The majority of
the works areas will be restored following the completion of the construction
works and these proposals will be combined with greening measures including the
planting of trees and shrubs to soften the built and engineering structures,
responsive design of the building height profile and massing on the LMC Loop
responding to the lowland context will serve to alleviate the visual impacts
for some of the identified VSRs from slight adverse without mitigation measures
(Day 1 of operation phase) to negligible with mitigation measures fully
established (Day 1 and Year 10 of operation phase) . This
includes VSRs with views of the LMC Loop and/or Direct Link to the MTR LMC
Station including Residents of Lin Barn Tsuen Village Settlement (VSR 1);
Residents of Tung Chan Wai Village Settlement (VSR2) and transient VSRs Train
Travellers on LMC Spur Line (VSR 12). This is also due to factors such as the
viewing distance the viewing angle and the presence of intervening structures
and vegetation and nature of VSR.
Visual impacts on
VSRs with views of the WCR (including LMC Road/San Tin Highway) but in distance
to the LMC Loop, including Residents of Pun
Uk Tsuen Village
Settlement (VSR 8A); Residents of Chau Tau
Village Settlement (VSR 8B); Residents of
Ha Wan Fishermen Village Settlement (VSR 19) and Workers of Workshops and Container Storage along Kwu Tung Road West
(VSR 25), will also alleviate from slight adverse without mitigation measures (Day 1 of operation
phase) to negligible upon full establishment of planting along
the WCR (Year 10 of operation phase). This is
also due to the presence of intervening structures and vegetation screening
views to the works from the above VSRs.
The visual amenity
for a number of VSRs with direct views of the LMC Loop, WCR and Direct Link to
MTR LMC Station (viaduct) will be significantly changed as result of the
proposed development. This includes views of Travellers
and Staffs at LMC Cross-boundary Infrastructure Facilities (VSR 11);
Travellers on Planned Boundary Patrol Road to the West
of LMC Loop (VSR 16) and Vehicle
Travellers and Pedestrians along Ha Wan
Tsuen Road (VSR 23). For these
VSRs the implementation of the proposed landscape and visual mitigation
measures such the creation of landscape buffer and ecological areas and the
responsive urban design for proposed institutional development on the LMC Loop,
responsive design of viaduct structures integrated with existing Spur Line and
MTR LMC Station, woodland and roadside
planting along Ha Wan Tsuen Road, and restatement of affected fishponds will
mitigate the predicted impacts from moderate adverse Day 1 during operation
phase without mitigation measures, to slight adverse during operation phase
(Day 1) and negligible during operation phase (Year 10) upon full establishment
of the above mitigation measures.
Travellers on Existing Boundary Patrol
Road at Ma Tso Lung (VSR 22) and Staffs of
HKPF Lok Ma Chau Operation Base (VSR 26) have views
of the LMC Loop, the ECR (at-grade/depressed road/underpass) and the Flushing
Water Service Reservoir at Horn Hill. The
implementation of the proposed landscape and visual mitigation measures such
the creation of landscape buffer and ecological areas and the responsive urban
design for proposed institutional development on the LMC Loop, responsive
design of the ECR integrated with the rural lowland and fishpond context,
woodland and roadside planting along ECR
and reinstatement of affected fish ponds will mitigate the predicted impacts
from moderate adverse Day 1 during operation phase without mitigation measures,
to slight adverse during operation phase (Day 1) and negligible during
operation phase (Year 10) upon full establishment of the above mitigation
measures.
The visual amenity of a number of VSRs, located in
distance to the LMC Loop, with views towards the WCR (including road works
along Hai Wan Tsuen and LMC Roads, and slip road connecting to San Tin
Highway), including Travellers and Staffs at Lo Ma Chau
Cross-boundary Bus Terminal (VSR 3), Vehicle
Travellers along Fanling and San Tin Highways (VSR 4), Vehicle Travellers and Pedestrians along LMC Road (VSR 5), Residents along Lok Ma
Chau Road (VSR 24), will also alleviate from moderate adverse Day 1 during operation phase without mitigation
measures, to slight adverse during operation phase (Day 1) and negligible
during operation phase (Year 10). This is evident through the implementation of
mitigation measures including limited works area, tree preservation, responsive
design of road alignment and structures and replanting of roadside areas.
This is also due to the integration of proposed road works along existing
infrastructure corridor that would minimise the visual intrusion to adjacent
rural landscape.
Other residents of Shun Yee
San Tsuen (VSR 18), Tse Hoo Hang Settlement
(VSR 13) and Ma Tso Lung Village
Settlement (VSR 21) have views of the at-grade road section the ECR at
Ma Tso Lung. The implementation
of the proposed landscape and visual mitigation measures such as limited works
area, tree preservation, responsive design of road alignment and structures and
replanting of woodland and roadside area will alleviate the predicted impacts
from moderate adverse Day 1 during operation phase without mitigation measures,
to slight adverse during operation phase (Day 1) and negligible during
operation phase (Year 10) upon full establishment of the above mitigation
measures.
For VSRs located
further afield including the Residents of Liu Pok Village Settlement (VSR 14) and
Travellers and Staffs at Lo Wu Cross-boundary Infrastructure Facilities (VSR
17) the predicted negligible level of impact will continue through to the
operation phase (Year 10). This is largely due a combination of the viewing
distance and the screening effect of the intervening landform.

impacts (Day 1/ Year 10) on VSRs as a result of individual DPs under Schedule
2.

11.9.1 Photomontages
A
series of computer generated images or photomontages have been prepared for the
proposed works demonstrating the worst-case scenario for the identified VSRs
and these are presented as Figures 11.10a to t. The
photomontages of the proposed works show the existing conditions, Day 1 of
Operational Phase after the completion of the construction phase in the absence
of mitigation measures and Day 1 of the Operational phase with mitigation
measures. The images for Year 10 of the Operational Phase with mitigation
measures are used to demonstrate the predicted residual
impacts, which would exist in the design year during the operational phase
taken as between 10 and 15 years after the completion of the construction
phase. The following text provides a description of each of the vantage points
which form the basis of the photomontages and the predicted impact of the
proposed scheme. The
building design within the LMC Loop is indicative and subject to change upon
detailed design in respect of future development.
11.9.1.1 Vantage Point A (VSR 5
Vehicle Travellers and Pedestrians along Lok Ma Chau Road)
This
vantage point (Figures 11.10a and 11.10b refer) shows the proposed
WCR (DP2), Direct Link to MTR LMC Station (DP3) and the developments within
LMC Loop at a distance of 620m. The image shows the scale of the proposed road widening
works for the existing Ha Wan Tsuen Road in the middle ground and the form of
the built development for the LMC Loop in the background. It shows the proposed
mitigation measures for the built form of the R&D / C&C buildings and
the Education Zone which includes the scale, orientation and massing of the
buildings responding to the rural setting. The
image with mitigation measures demonstrates the effectiveness of the tree
planting lining the WCR in screening views of both the infrastructure and the
built form of the development. Greening measures on buildings on the LMC
Loop soften the built form and improves the visual amenity. It also shows how a sense
of visual integration can be achieved with the landscape mitigation measures in
combination with the preserved landscape resources including woodland areas.
11.9.1.2 Vantage Point B (VSR 10
Residents of Ping Hang Village Settlement)
The
view from this location (Figures 11.10c and 11.10d refer) shows the proposed
buildings and developments at a close proximity from ground level at a distance
of approximately 170m. The image shows the scale of the proposed buildings and
structures of the LMC Loop and the ECR (DP6). The main features of the LMC
Loop development
include the DP1 Ecological Area to the southwest, the Education and R&D /
C&C) development in the central portion and DP5 Sewage Treatment Works to
the east. This view clearly demonstrates the responsive design of the
architecture to the existing setting with the gradation height profile extending
from the southern and eastern peripheries of the site. It also demonstrates the
existing visual amenity available to VSRs including the Residents of Ping Hang and
Tai Law Hau Village
Settlement, Staffs at HKPF Operation Base and Future visitor
to Planned Eco-lodge and how this view will change with the introduction of the ECR
depressed road and underpass sections. The introduction of the proposed landscape mitigation measures
including the buffer tree planting along the eastern periphery of the LMC
Loop and the
planting associated with the DP1 Ecological Area serves to enhance the sense of
visual integration between the development and its setting and soften the
architectural form of the main buildings and structures. The tree planting alongside
of the depressed road and on landscape deck of the underpass section associated with the
ECR is
designed to screen it in views from this location. This view demonstrates how through careful
and responsive design the impacts can be mitigated to an extent and the scheme
better integrated into the future landscape context.
11.9.1.3 Vantage Point C (VSR 15
Travellers on Planned Boundary Patrol Road to the east of the LMC Loop)
This
vantage point (Figures 11.10e and 11.10f refer) shows the
relatively close proximity, approximately 300m, of the view from the planned
Boundary Control Road to the proposed development within the LMC Loop and
includes a representation of the Secondary Boundary Fence newly
constructed lining
the road. The ground level view extends southwest from the fishponds near Hoo
Hok Wai across the abandoned meander to the north-eastern edge of the LMC
Loop. The sand coloured area in the middle ground of the Day 1 image without
mitigation represents the site formation works extent. This image illustrates
the scale of the proposed buildings and structures for the R&D / C&C
portion development, a small area of commercial and government developments; and the location of DP5
Sewage Treatment Works. As demonstrated by the image the scale of the proposed
scheme is in tune with its landscape context and the effectiveness of the
landscape mitigation measures particularly the buffer tree planting in reducing
the scale of the development, softening the built form and enhancing the sense
of visual integration. It also demonstrates that through the careful design of
the landscape mitigation measures the amenity of the river course can be
maintained.
11.9.1.4 Vantage Point D (VSR 11
Travellers and Staffs at LMC Cross-boundary Infrastructure Facilities)
The view from the
LMC Cross-boundary Infrastructure Works east towards the LMC Loop (Figures 11.10g and 11.10h refer) at a distance of approximately
850m is characterised by existing developments including the viaduct of
the LMC Spur Line to the south and the high-rise developments of Shenzhen and the
engineered form of the river channelization works to the north. The central
portion of the view shows the mitigation wetlands and reed cell for
waste water polishing to the east of the PTI of the MTR LMC Station. The introduction of the proposed viaduct and
elevated PTI for
the DP3 Direct Link to MTR LMC Station will mirror the form of the
existing LMC Spur Line structure. The elevated PTI will be built over the
existing PTI at ground level. The indicative location of elevated PTI is shown
on Figure 11.6l, its form and finishes will be mirror and integrated with the
Station building. These
structures will dominate future views although there may be glimpsed and
partial views of some of the proposed built development in LMC Loop in the background. The main form of mitigation for these structures
will be in their design and the alignment of the Direct Link.
11.9.1.5 Vantage Point E (VSR 23
Vehicle Travellers and Pedestrians along Ha Wan Tsuen Road)
The view northeast
along Ha Wan Tsuen Road (Figures 11.10i and 11.10j refer) is
characterised by the dense tree and shrub planting to the east and west of the road corridor which largely serves to screen
views of the landscape beyond. There are glimpsed views of the high-rise
development of Shenzhen beyond the tree planting at the entrance square of Ha Wan Tsuen. At a distance of
approximately 275m the proposed development including a block associated with
the R&D / C&C development to the north and Education Zone to the south
will serve to foreshorten the available views of Shenzhen. The foreground of
these future views will also feature the road widening works associated with
DP2 WCR. Owing to the enclosed nature of the existing views the proposals will not
result in a significant change in either the landscape character or the visual
amenity of the area. As demonstrated by the image the DP2 proposals have been
designed to preserve as much of the existing roadside tree planting and this
includes the widening of the central median to accommodate existing trees. The viaduct of Direct Link to LMC Station from the
LMC Loop over northern portion of Ha Wan Tsuen will not be perceived in this
viewing location as it is screened by the mature trees in the village.
11.9.1.6 Vantage Point H (VSR 24
Residents along Lok Ma Chau Road)
Views along the
Lok Ma Chau road corridor (Figures 11.10k and 11.10l refer) are largely
contained by a combination of the existing roadside development and vegetation
including mature trees. The views available to many of the residents lining the
road are also screened by intervening vegetation and structures and in some
cases the orientation of the houses results in views extending away from
the road. This view extends south east along the road which will be widened to
accommodate cycle track and footpath to the east and new planting area as part of the DP2 WCR
proposals. These proposals include the introduction of series of small lengths
of noise barrier ranging in height from 0.8m to 5m in height.
The noise barriers show on the image is 3m high. Despite this the road widening works
will for the most part not have a significant impact on the landscape or the
visual amenity of the road corridor. In addition the design of the road scheme
has been modified to preserve more mature trees which line the existing
carriageway that would significant reduce the visual impact to
the road corridor as well as to villagers living alongside of LMC Road.
Given
the tallest 5m noise barrier section is occupied only a short section of LMC
Road adjacent to existing 2.5m high fence wall of a village house, hence
Vantage point H shows a section of WCR has two numbers of 3m high noise
barriers that considered as the worst case scenario of visual impact as a result
of proposed noise mitigation measures along LMC Road.
11.9.1.7 Vantage Point I (VSR 7
Residents Lok Ma Chau Village Settlement)
View northwest from this location (Figures 11.10m and 11.10n refer) shows the proposed buildings
and developments at relatively close proximity (approximately 360m) from a
position at ground level. The existing view shows an area of fishponds,
grassland and agricultural fields in the foreground with the course of the abandoned meander in the
middle ground and to the east with views of the LMC Loop partially screened by
intervening tree and shrub growth. The high-rise development of Shenzhen to the
north of the LMC Loop is apparent in the background. The image shows the scale of the proposed
buildings and structures of the LMC Loop with the R&D / C&C component
of the development to the west and the Education Zone to the east. It
demonstrates the responsive design of the architecture to the existing setting
with the gradation height profile extending from the southern periphery of the site and
scale which is in tune with the expanse of the Loop and the high-rise
development in the background. The introduction of the proposed landscape
mitigation measures including the buffer tree planting along the eastern edge and
the planting
associated with the DP1 Ecological Area serves to enhance the sense of visual
integration between the development and its setting and soften the
architectural form of the main buildings and structures. Although
views towards WCR along Ha Wan Tsuen Road (DP2) and Direct Link to LMC Station
(DP3) from this viewing location is largely screened by intervening vegetation,
partial view of these DPs might be seen when moving the viewing location to the
west. This
view demonstrates how through careful and responsive design the impacts can be
mitigated to an extent and the scheme better integrated into the future
landscape context.
11.9.1.8 Vantage Point K (VSR 26
Staffs of HKPF Lok Ma Chau Operation Base)
Although
this vantage point is located to the northwest of the Lok Ma Chau Operation Base
it represents the view southeast towards DP6 ECR at-grade
road section at
a distance of 142m and DP7 Flushing Water Service Reservoir beyond (Figures 11.10o and 11.10p refer). The existing view is formed by
fishpond in
the foreground, shrubland and abandoned agricultural fields in the
middle ground, grassed knolls and the undulating form of the LMC
ridgeline in the background. The construction of the DP6 ECR and DP7 Flushing
Water Service Reservoir will introduce two new structures in the middle ground
of the view. The ECR will be at-grade for the section visible from this
location along existing Boundary Patrol Road approaching Ma
Tso Lung. The
proposed introduction of tree planting alongside the ECR will serve to screen
views of the carriageway and improve the integration of the scheme within the
local landscape context. This sense of integration will improve as the trees
mature and visually coalesce with the adjacent tree
clusters in the areas.
The
proposed location of the Flushing Water Service Reservoir has been designed in
semi-sunken form to avoid changing the naturalistic form of the ridgeline
however there is still need to place the structure at an elevated location on
the hillside (grassed knoll) to provide adequate water pressure. Other mitigation measures for the reservoir
include the use of recessive colours for the finishes and the introduction of
tree planting in front of the built structures. In addition, tree will be
planted along the access from existing Boundary Patrol Road and hydroseeding
will be applied on cut slopes which has a gradient more than 30 degree. These measures serve to reduce the visual
prominence of the proposed structure, integrated with existing grassed hill
landscape and so minimise the landscape and visual impacts arising from the
works.
11.9.1.9 Vantage Point L (VSR 18
Residents of Shun Yee San Tsuen)
The
main view from Shun Yee San Tsuen looking west to the grassland shows the much
closer views (approximately 145m) of the DP6 ECR (Figures 11.10q and 11.10r refer). Views
looking towards the LMP Loop located over 1200m away from the village are
blocked by the intervening landform and LMC ridge. The existing view extends across the
valley floor to the wooded lower slopes of the Lok Ma Chau Ridge surrounding
Tse Koo Hang village and views of the summits of the hills beyond. In this area the ECR will
be constructed on a low embankment punctuated by animal passages to provide for
the movement of animals across the road alignment. The introduction of
vegetation for the embankment slopes and roadside tree planting is designed to
integrate the engineered for the road embankment into the existing landscape
context and screen views of the carriageway. As the trees mature they will
visually coalesce with the existing woodland and tree clumps within the
vicinity to enhance the visual integration of the proposals within the
landscape context.
11.9.1.10 Vantage Point O (VSR 20
Public Users of the LMC Lookout)
This
image represents an elevated view (56.8mpD) from the Lok
Ma Chau Police Station adjacent to the LMC Lookout looking northeast towards the LMC
Loop at a distance of approximately 680m (Figures 11.10s and 11.10t refer). The image shows the scale of the proposed
buildings and structures of the LMC Loop with the main features being R&D /
C&C portion of the development to the east and west and the Education Zone
in the central portion. The DP1 Ecological Area located along the southern
periphery of
the development is visible in the middle ground and provides a transition
between the flat expanse of the fishpond and agricultural plain, the abandoned
meander and the built form of the new development. This view clearly
demonstrates the responsive design of the architecture to the existing setting
with the gradation height profile extending from the southern and eastern peripheries
of the site. The introduction of the proposed landscape mitigation measures
including the buffer tree planting and the planting associated with the DP1
Ecological Area serves to enhance the sense of visual integration between the
development and its setting and soften the architectural form of the main
buildings and structures. The image also shows the breezeway/ view
corridor designed in the central portion of
proposed development. Besides, regarding to the viewing distance and
intervening landform and mature trees in Ha Wan Tsuen, views toward proposed
WCR (DP2), ECR (DP6) and Direct Link to LMC Station (DP3) have been blocked and
forms a very small component in this visual context. This view demonstrates how through
careful and responsive design the impacts can be mitigated to an extent and the
scheme better integrated into the future landscape context.
11.10.1 Landscape Impact
With the implementation of a responsive
design for the proposed built elements, engineering proposals and DPs; the
adoption of greening measures, the combination of new tree planting, preserved trees and restoration of the disturbed areas following the
completion of the works, compensation for the loss of existing
trees, woodland, fishponds and wetlands the residual
impacts on the majority of the identified landscape resources for
the LMC Loop Development under EIAO Schedule 3 would be
slight to negligible.
Tree Impact
There are approximately 6,660 existing trees on the LMC Loop and within the limit of works areas. No Registered Old and Valuable Trees” and/or “Champion Trees are found. Loss of existing trees will be limited to trees within the Loop and alongside the proposed Direct Link to MTR LMC Station, WCR and ECR; and access road for the Flushing Water Service Reservoir. A large proportion of these trees have naturally colonised the site and their overall amenity value is not considered to be high. Based on the broad brush tree survey contained in Appendix 11-1 and the preliminary engineering layouts of proposed works contained in Chapter 2 of this EIA, approximately 279 trees are proposed to be transplanted to new planting areas proposed on the LMC Loop and alongside of proposed road improvement works, and approximately 4,022 trees are inevitable to be in conflict with the construction works and recommend for felling. New planting areas within the LMC Loop including tree planting in landscape buffer, open spaces and roadside planting areas will accommodate approximately 5,000 new trees. Planting of more broad-leave tree species will be considered where space allows and location is suitable for tree establishment. This planting concept would create comfortable shaded area for pedestrians and visitors in open spaces.
New planting areas along the road alignment of WCR (DP2), ECR (DP6) and access road to Flushing Water Service Reservoir (DP7) will accommodate approximately 2,600 new trees.
For the affected tree on the sloping areas, due to constrained growth conditions, whip planting will be proposed on slopes which have gentler gradient at a planting distance of about 1500mm. Slopes have a gradient more than 30 degree, hydroseeding will be applied instead. Upon full establishment of whip planting and hydroseeding, greening coverage on affected sloping areas will be reinstated. Following the above planting principles, the newly formed and remnant sloping areas along the road alignment would accommodate approximately 500 whips.
Based on a preliminary estimation, the above planting proposal would achieve a replanting ratio of minimum 1:1 in terms of quantity and quality except for slope works according to ETWB TCW No. 3/2006. This tree replanting ratio would compensate the total girth and number of tree loss as well as the total number of tree loss on sloping area. Given the constraints of growing condition and safety reasons of planting larger size tree stock on sloping areas, greening measures on new formed and remnant slopes, including extensive hydroseeding and whips planting, would restore the quality of these greenback drop in rural area.
The retention of existing trees through
their preservation in-situ and transplanting and the successful establishment
of the newly planted trees will enhance amenity of the local areas and
providing for the thermal comfort of pedestrians, visitors and users of the LMC
Loop Development. In the wider landscape context, the green backdrop will be
reinstated upon full establishment of replanting proposals within the LMC Loop,
along proposed roads and on sloping areas.
The above recommendation on existing trees
is preliminary and subject to the detailed tree survey and tree felling
application to be submitted for LandsD/Government approval at detailed design
stage of the project in accordance with ETWB TWC No. 3/2006 Tree Preservation.
Landscape
Resources
The significant
impact on LR11.1
Marsh on the Loop will be
alleviated to negligible (Year 10) with full establishment of landscape
mitigation measures including creation of compensation
wetlands on-site in EA of the LMC Loop and in off-site locations,
The
slight adverse impacts predicted during the operational phase (Day 1) would be
alleviated through the growth to maturity of the proposed landscape mitigation
measures, including replanting for woodland, stream and
channel side and roadside planting areas, off-site compensation of fishponds
and marshes, to
negligible during the operational phase (Year 10) for Lok

impact on the following LRs would be not affected by the works or being mitigated to
a negligible level through the growth to maturity of the proposed landscape mitigation
measures including replanting for woodland, stream and
channel side and roadside planting areas, off-site compensation of fishponds
and marshes, The
negligible impacts predicted during the operational phase (Day 1) would be maintained during the operational
phase (Year 10) for Cross-boundary Infrastructure and Facilities (MTR LMC Station)

Despite
a large amount of self-seeded weedy trees being lost with the development of
the LMC Loop proposals this will be mitigated through the planting of new
woodland and ornamental tree planting throughout the development
area, particular in the woodland buffer area along the northern edge of the
Loop. Therefore LR’s such as the Trees on the Loop (LR4A) would be subject to a slight beneficial impact as the trees
mature.
The following are

With the implementation of the proposed mitigation measures, the
predicted impacts on LRs as a result of the LMC Loop Development and DPs will
largely be alleviated to negligible level of impact during the construction and
operation phases (Year 10) of the project. These mitigation measures include
preservation of existing vegetation, reinstatement of temporary works areas;
implementation of mitigation planting, transplantation of existing trees, the
use of greening associated with the built structures, tree planting along
planned road corridor and built structures and compensation for the loss of
woodland, fishponds and wetlands. With the full
establishment of the proposed mitigation measures and the growth to maturity of
the proposed tree and shrub planting, woodland and wetland, the LMC Loop
Development and DPs will be well integrated within the
future landscape context.
Landscape
Character Area
The residual impacts on the
majority of the identified landscape character areas
as a result of the LMC Loop Development under EIAO Schedule 3 would be negligible including Sam Po Shue Lowland Rural
Landscape (LCA 1), LMC Cross-boundary Infrastructure and Facilities Landscape
(LCA 2), San Tin Lowland Rural Landscape (LCA 3), Ki Lun Shan Lowland Rural
Landscape (LCA 4), LMC Lowland Rural Landscape (LCA5), LMC Hillside Landscape
(LCA 6), Ma Tso Lung Lowland Rural Landscape (LCA7) and
Hoo Hok Wai Lowland Rural Landscape (LCA 9).
Although the LMC Loop is subject to a significant change of character as a
result of proposed institution development and associated infrastructure and
utilities facilities, impact on the LMC Loop Riverside Landscape (LCA 8) will
be alleviated to a slight level through full establishment of the mitigation
measures.
The following are
residual impacts (Year 10) on landscape character areas as a result of
individual DPs under Schedule 2 with the adoption and full establishment of the
recommended landscape mitigation measures.

As with the predicted impacts on the LRs and LCAs of the
Assessment area with the full establishment of the proposed landscape
mitigation measures, the growth to maturity of
the proposed tree and shrub planting, compensation
of woodland, wetlands and fishponds, the LMC Loop Development and DPs will be well integrated with the character of the future landscape
context.
11.10.2
Visual Impact
As has been described above the majority
of the works areas disturbed by the proposed works will be restored following
the completion of the construction phase of the project. These restoration
measures in combination with the full implementation of the landscape and
visual mitigation measures will do much to mitigate the visual impacts. The residual
impacts on the majority of the identified VSRs
would be negligible with exception of Ha Wan
Tsuen Village Settlement (VSR 6) and Residents of LMC Village Settlement (VSR
7), Residents of Tai Law Hau Village Settlement
(VSR 9), Residents of Ping Hang
Village Settlement (VSR 10), and Planned
Visitors to the Eco-lodge (PVSR 10A), Travellers on
Planned Boundary Patrol Road to the East of LMC Loop (VSR 15)
and Public Users of LMC Lookout (VSR 20)
who will experience a moderate to slight residual impacts due to their
proximity to the proposed works or have an overview of the LMC Loop.
The significant impact
to the visual amenity of Residents of Ha Wan Tsuen Village Settlement (VSR 6) and Residents
of LMC Village Settlement (VSR 7) will be alleviated to a slight level
upon the full establishment of mitigation measures including the limited works areas, responsive design of institutional
development, road alignment and viaduct, noise barrier structures, the use of
vertical greening measures where possible on built structures and the
restoration of the disturbed areas with roadside planting. These VSRs have views to the proposed institutional developments associated with infrastructure and utilities facilities on the LMC Loop, WCR road works and noise
barriers along Ha Wan Tsuen Road and LMC Road and the Direct Link to MTR LMC
Station (viaduct).
Residents of Tai Law Hau Village
Settlement (VSR 9), Residents of Ping Hang
Village Settlement (VSR 10), and Planned
Visitors to the Eco-lodge (PVSR 10A), Travellers on
Planned Boundary Patrol Road to the East of LMC Loop (VSR 15)
and Public Users of LMC Lookout (VSR 20)
have views of the LMC Loop, the ECR (at-grade/depressed
road/underpass) and the Flushing Water Service Reservoir at Horn Hill. The
predicted significant adverse impact on these VSRs will be mitigated to slight
adverse upon full establishment of the mitigation
measures such as the creation of landscape buffer and
ecological areas and the responsive design for proposed institutional
development on the LMC Loop, responsive design of the ECR integrated with the
rural lowland and fishpond context, woodland and roadside planting along ECR
VSRs with views of the LMC Loop and/or
Direct Link to the MTR LMC Station include Residents of Lin Barn Tsuen Village Settlement (VSR 1); Residents
of Tung Chan Wai Village Settlement (VSR2) and transient VSRs Train Travellers
on LMC Spur Line (VSR 12). The predicted slight adverse impact on
these VSRs will be mitigated to negligible
upon full establishment of mitigation measures including the planting of trees and shrubs to soften the built and engineering
structures, responsive design of the building height profile and massing on the
LMC Loop responding to the lowland context.
VSRs with views of the WCR (including LMC Road/San Tin Highway) include Residents of Ha Wan Fishermen Village Settlement (VSR 19) and Workers of Workshops and Container Storage along Kwu Tung Road West (VSR 25). The predicted slight adverse impact on these VSRs will be mitigated to negligible upon full establishment of planting along the WCR (Year 10 of operation phase).
VSRs with views of the LMC Loop, WCR and
Direct Link to MTR LMC Station (viaduct) include Travellers on Planned Boundary
Patrol Road to the West of LMC Loop (VSR 16) and Vehicle Travellers and Pedestrians along Ha Wan Tsuen Road (VSR 23).
The predicted moderate adverse impact on these VSRs will be mitigated to negligible upon full establishment of the mitigation
measures such as the creation of landscape buffer and
ecological areas and the responsive urban design for proposed institutional
development on the LMC Loop, responsive design of viaduct structures integrated
with existing Spur Line and MTR LMC Station, woodland and roadside planting along Ha Wan Tsuen Road.

In view of the assessment according to the Annex 10 of the EIAO-TM, the landscape and visual impacts of the proposed works would be ‘acceptable with mitigation measures’. In other words, ‘there would be some adverse effects, but these can be eliminated, reduced or offset to a large extent by specific measures’.
