Updated Tree Schedule |
DEVB TC(W) No. 4/2020 - Tree Preservation;
DEVB TCW No. 6/2015 - Maintenance of Vegetation and Hard Landscape Features; and,
9.4.1.1.1 This involves a baseline survey of the existing landscape resources (LRs) and landscape character areas (LCAs) and comprises of a desk-top study of relevant background reports, topographical maps, information databases and photographs verified through comprehensive field study.
9.4.1.1.2
The LRs include physical landscape
resources such as the physical topography, water bodies, open space and
vegetation; and human landscape resources which include cultural heritage and
historical features.
9.4.1.1.3
The LCAs represent broad tracts of landscape which
have a consistent character based on a consideration of topography, vegetation
types and land use patterns. The “Landscape Value Mapping Study in Hong Kong”
will be reviewed to get an understanding of the landscape characters within the
Study Area for LIA.
9.4.1.2.1 Assessment of the degree of sensitivity of the individual LRs /LCAs is influenced by a number of factors including whether the resource/character is common or rare, whether it is considered to be of local, regional, national or global importance, whether there are any statutory or regulatory limitations/ requirements relating to the resource, the quality of the resource/character, the maturity of the resource, and the ability of the resource / character to accommodate change. The sensitivity of each landscape feature and character area is classified as follows:
9.4.1.3.1
Identification of potential sources of landscape
impacts: These are the various elements of the construction works and
operational procedures that will generate landscape impacts.
9.4.1.3.2
Identification of the magnitude of change
Identification of the magnitude of change: The magnitude of change depends on a
number of factors including the physical extent of the impact, the landscape
and visual context of the impact, the compatibility of the Project with the surrounding
landscape; and the time-scale of the impact - i.e. whether it is temporary
(short, medium or long term), permanent but potentially reversible, or
permanent and irreversible. Landscape impacts have been quantified wherever
possible.
9.4.1.3.3 The magnitude of landscape impacts is classified as follows:
9.4.1.4.1 Identification of potential landscape mitigation measures, and programme for implementation : These may take the form of adopting alternative designs or revisions to the basic engineering and architectural design to prevent and/or minimize negative impacts; remedial measures such as colour and textural treatment of building features; and compensatory measures such as the implementation of landscape design measures (e.g. tree planting, creation of new open space, etc.) to compensate for unavoidable negative impacts and to attempt to generate potentially positive long term impacts. A programme for the mitigation measures is provided. The agencies responsible for the funding, implementation, management and maintenance of the mitigation measures are identified in Tables 9.12.1 and 9.12.2 and the mitigation measures are illustrated in Figures 9.14 to 9.16; Figures 9.42 to 9.43; Figures 9.71 to Figure 9.75 and Figures 9.110 to 9.113.
9.4.1.5.1 Through the consideration of the magnitude of the various impacts and the sensitivity of the various landscape resources it is possible to categorise impacts in a logical, well-reasoned and consistent fashion. Table 9.4.1 shows the rationale for dividing the degree of significance into four thresholds, namely insubstantial, slight, moderate, and substantial, depending on the combination of a negligible-small-intermediate-large magnitude of change and a low-medium-high degree of sensitivity of landscape resource / character. Impact significant is taken to be adverse unless stated otherwise as beneficial.

9.4.1.5.2 The degree of Impact significant thresholds are defined as follows:
9.4.1.5.3 Prediction of Acceptability of
Landscape Impacts: Landscape impacts are products of magnitude of change and
the relative sensitivity of the landscape sensitive receiver. Ultimately, the
acceptability of the Project is dependent upon the significance of the residual
impacts in accordance with the five criteria set out in Annex 10 of the
EIAO-TM, namely ‘beneficial’, ‘acceptable’, ‘acceptable with mitigation
measures’, ‘unacceptable’ and ‘undetermined’.
9.4.1.6.1 Before adopting other mitigation
measures to alleviate the impacts, alternative design(s) and construction
method(s) that would avoid or reduce the impacts on landscape amenity, or that
would make the Project more compatible with the setting, examination of
alternative designs and construction methods will be examined.
9.4.1.7.1 Cumulative impacts on landscape
resources and landscape character areas will be identified and assessed.
9.4.1.7.2 The findings of the LIA are
presented and supported by a range of illustrative materials such as aerial
photograph, photographs and plans etc.
9.4.1.9.1 Visual resources and key visually sensitive
receivers (VSRs) within the Visual Envelope which would be affected by the
proposed works will be identified. Minimum viewing distance of each VSR is also
determined.
9.4.1.10.1 Visual sensitivity considers the
impact on views to the subject site from potential VSRs. A number of factors
affecting the sensitivity of VSRs for evaluation of visual impacts are as
follows:
9.4.1.11.1 Various elements located within the
subject site that would generate visual impacts during construction and
operation phases will be identified.
9.4.1.12.1 Visual impacts are determined by
evaluating the conditions of the existing landscape and the visual character of
the subject site and its surroundings, as well as the degree of integration of
the proposed work’s components with the existing landscape. Other major factors
affecting the magnitude of changes for assessing visual impacts are:
9.4.1.12.2 The potential magnitude of change is classified into four categories:
9.4.1.13.1 The significance of the visual
impacts is categorised as follows:
9.4.1.13.2 The impact significance will be determined. Table 9.4.2 shows the relationship between sensitivity and magnitude of change.

The following legislation, standards and
guidelines are applicable to the evaluation of landscape and visual impacts
associated with the construction and operation phases of the Project. Relevant
planning documents have been reviewed to gain an insight to the planning
intentions of the Study Area and its surroundings so as to assess whether the
proposed works can fit into the setting of the Project and its surroundings as
a whole.
Several LRs are identified within the Project boundary at Sung
Shan New Village and will potentially be affected by the Project. In addition
to Water Course (SSNV-LR3), these LRs include Plantation (SSNV-LR7) and Urban /
Residential Area (SSNV-LR9).
Several LRs are identified within the Project boundary at Tai
Wo and will potentially be affected by the Project. In addition to Water Course
(TW-LR5), these LRs include Grassland (TW-LR7), Waste Ground (TW-LR12) and
Urban / Residential Area (TW-LR13).
Several LRs are identified within the Project boundary at Lin
Fa Tei and will potentially be affected by the Project. In addition to Water
Course (LFT-LR4), these LRs include Secondary Woodland (LFT-LR8), Plantation
(LFT-LR10), Waste Ground (LFT-LR11) and Urban / Residential Area (LFT-LR12).
Several LRs are identified within the Project boundary at Ha Che and will potentially be affected by the Project. In addition to Water Course (HC-LR3), these LRs include Plantation (HC-LR9) and Urban / Residential Area (HC-LR11).

The visual envelope (VE) at each of the four
sites; the area from which the proposed works will be seen, is shaped by a
combination of the existing residential and infrastructural development, the
surrounding landform and its associated vegetation.
9.8.1.1.1 The VE for the proposed scheme
extends in a narrow corridor from the south of Tong Tau Po Tseun along the
southern edges of Sung Shan New village and extending to the south of a wooded
knoll located to the east of Sung Shan New Village. The extent of the VE is
illustrated in Figure 9.08. Within the VE the primary Zone of Visual
Influence (ZVI) is described as follows.
9.8.1.1.2 This primary ZVI follows the alignment of
the existing channel corridor. Owing to a combination of the existing built
structures, landform and vegetation this zone is largely restricted to the area
immediately adjacent to the proposed works area / channel alignment. This is the area with the greatest
visibility of the proposed works largely shaped by the woodland margins of the existing channel edges
and the high fence walls of industrial and residential garden boundaries lining
the edges of the watercourse. The zone extends through some inaccessible areas
but briefly intersects with public roads and pedestrian footpaths crossing the
channel to the South of Sung Shan New village.
9.8.1.2.1 The VE for the proposed scheme
extends to the south and south east of Tai Wo in a broad zone, the southern and
eastern edges of which are defined by the landform and extent of woodland of
the uplands to the south of the study area. To the north the visual envelope is
defined by tree planting and built structures associate with the village
margins of Tai Wo and Cheung Po
villages. The extent of
the VE is illustrated in Figure 9.36. Within the VE, the primary ZVI is described
as follows.
9.8.1.2.2 This primary ZVI extends in a south easterly
direction across the open valley floor and lower slopes of the uplands to the
south of the Study Area. This is the area with
the greatest visibility of the proposed works largely shaped by the landform of the uplands and the woodland margins
of the higher slopes of the uplands to the south of the study area and the
existing woodland and plantation areas to the south of Tai Wo and Cheung Po
villages. The zone extends through some publicly inaccessible areas but briefly
intersects with public pedestrian footpaths aligned to the route of the channel
to the South of Tai Wo village.
9.8.1.3.1 The VE for the proposed scheme
covers two areas, associated with the channel upgrading works proposed within
Lin Fa Tei Village gateway area and adjacent to Kam Sheung Road and the more
extensive and separate area of works running to the south of Lin Fa Tei
village. The VE at this first area is defined by the corridor of Kam Sheung
Road and the extent of the open area occupied by car parking and the village
pond at Lin Fa Tei Village Gateway. The VE of the second area forms a broad
corridor extending across open land areas adjacent to the channel to the east
and west of Lin Fa Tei and forming a narrower corridor defined by village areas
at the centre of the proposed works area. The extent of the VE is illustrated
in Figure 9.63. Within the VE the primary ZVI is described as
follows.
9.8.1.3.2 This primary ZVI follows the alignment of
the existing channel corridors and covers areas of open waste ground and
abandoned farm land as well as extending to more developed areas. This is the
area with the greatest visibility of the proposed works largely shaped by the woodland margins of
the existing channel edges, village edges and private property boundaries. The
zone extends through some inaccessible areas to the south of Lin Fa Tei but
intersects with public roads and pedestrian footpaths crossing and following
the channel to the South and East of Lin Fa Tei village.
9.8.1.4.1 The VE for the proposed scheme
extends in a narrow corridor across the valley floor from A Kung Tin in the
north to the south of Ha Che village in the south of the Study Area, with
periodic extensions to this narrow corridor where the channel intersects with
roads, footpaths and open areas. The northern portion of the VE is located to
the east of Fan Kam Road between A Kung Tin and Chuk Hang and then crosses Fan
Kam Road and extends as a narrow corridor to the west of Kam Fan Road at Ha
Che. The extent of the VE is illustrated in Figure 9.101 to 9.102. Within the VE the primary ZVI is described as
follows.
9.8.1.4.2 This primary ZVI follows the alignment of
the existing channel corridor. Owing to a combination of the existing built
structures, landform and vegetation, this zone is largely restricted to the
area immediately adjacent to the proposed works area / channel alignment. This is the area with the greatest
visibility of the proposed works largely shaped by the woodland margins of the existing channel edges
and the high fence walls of industrial and residential garden boundaries lining
the edges of the watercourse. The zone extends through some inaccessible areas
but briefly intersects with public roads and pedestrian footpaths crossing the
channel adjacent to Shui Kan Shek at the northern part of the site and also
intersects with a section of Fan Kam Road between Ha Che and Chuk Hang villages
further to the south.

The proposed works will be the source of impacts inducing adverse
landscape and visual impacts during the construction phase and the operation
phase. It should be noted that some sources may actually induce positive
impact.
Impacts
during the operation phase will be permanent and irreversible. Sources of
operation phase impact will include:
There will be a number of impacts on LRs and LCAs during the
construction and operational phases prior to the implementation of the proposed
mitigation measures. However, these impacts will be confined to areas within
the Project boundary. The predicted impacts are described below and in Tables 9.10.5 – Table 9.10.8.
All other LRs within the Study Areas at the four sites are located entirely outside the Project boundary and will not be affected by the works. The magnitude of change for those LRs outside the Project boundary would be negligible, and need not be assessed as the impact significance will be insubstantial.

Contractors during construction |
|
|
Trees / woodland within the Project Site which are unaffected by the
works shall be protected and preserved during the construction phase. 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. |
||||
CM02 |
Offsite Compensatory Tree Planting |
DSD |
Contractor |
Contractor during construction. |
|
|
If removal of trees is unavoidable due to construction impacts, trees
will be compensated where technically feasible. Owing to the constricted
nature of the site boundary, if all planting opportunities within the site
have been utilised, offsite planting locations / planting locations outside
the site boundary may be considered, which can be planted at an earlier stage
of the works. |
||||
CM03 |
Works Area and Temporary Works Areas (Good Site Practice) |
DSD |
Contractor |
Contractors during construction |
|
|
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, and the location and
appearance of site accommodation and site storage. The site office or
temporary above-ground structures shall be sited in locations which are not
visually prominent. |

CM06 |
Decorative Screen Hoarding |
DSD |
Contractor |
Contractors during construction |
|||
|
Decorative screen hoarding will be erected along areas of the
construction works site boundary where the works site borders publically
accessible routes and/or is close to visually sensitive receivers (VSRs) to
screen undesirable views of the works site. It is proposed that the screening
be compatible with the surrounding environment and where possible,
non-reflective, recessive colours be used. |
||||||
CM07 |
Light Control |
DSD |
Contractor |
Contractors during construction |
|||
|
Construction and night time lighting glare will be controlled to
minimize glare impact to adjacent VSRs during the construction stage. This is
considered a general measure for good practice. |

Detailed Design Considerations |
DSD |
Designer / Consultants |
N/A |
|
|
Detailed design of
development components should reduce landscape footprint and visibility of structures.
The area allowed for necessary structures should be reduced to a practical
minimum. |
||||
OM02 |
Aesthetically Pleasing Design |
DSD |
Designer / Consultants |
N/A |
|
|
The form, textures,
finishes and colours of the proposed works components should be compatible
with the existing surroundings. Light earthy tone colours such as shades of
green, shades of grey, shades of brown and off- white may be utilised where
technically feasible to reduce the visibility of the development components,
including all roadwork, buildings and noise barriers etc. To further improve
visual amenity, natural building materials such as stone and timber, should
be preferably adopted for architectural features, where technically feasible. |
||||
OM03 |
Responsive Design of Channel alignments |
DSD |
Designer / Consultants |
N/A |
|
|
The proposed
use of a
responsive design for
the disposition of the main elements of the proposed drainage scheme
including the routing of the channel to enable the preservation of
significant landscape elements, such as large trees and the development of
aesthetic treatments in response to the urban context within which the
projects are to be implemented. The disposition and height profile of the
developments and above ground utilities structures to respond to the existing
context particularly the existing landform and preserved trees. Proposals
designed to minimise the single use of space for functional and utility
purposes and promote integrated design solutions. Create a subtle transition
at the edges of the sites to enhance
the sense of
visual integration with the existing context and avoid abrupt
transitions between the existing and proposed built environment. |
||||
OM04 |
Design of Engineering Structures |
DSD |
Designer / Consultants |
N/A |
|
|
The design of the
proposed Engineering Structures such as the proposed retaining culverts and
footbridges should pay particular attention to the appearance and
construction methods. 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. 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 engineering
structures shall avoid any unnecessary visual clutter; this would be achieved
through the co-ordination of the various engineering disciplines involved to
arrive at integrated design solutions. |
||||
OM05 |
Design of Retaining Walls and Channel Embankments |
DSD |
Designer / Consultants |
N/A |
|
|
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" as well as DSD Practice Note No. 1/2015 Guidelines on
Environmental and Ecological Considerations for River Channel Design. 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. 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. Larger
sized tree stock shall be missed with whip sized trees to create a more
diverse woodland structure enhance the screening effect from day one.
Hydroseeding will be applied on slope has a gradient more than 30 degree. |

OM06 |
Compensatory Planting Proposals at Channel edges |
DSD |

DSD and other government departments |
|
|
All compensatory
planting of trees is to be carried out in accordance with ETWB TCW No.
10/2013. A total woodland compensation area of 5.54 ha is proposed. The planting
proposals will utilise native species. Some compensatory shrub and ground
cover planting will also be provided within the channel edge area to create
more structurally diverse woodland and a layered vegetated edge to the
watercourse. |

The impacts on LCAs as a result of the proposed works are assessed as follows and are described below and in Table 9.10.8.
9.14.1.
Significance of
Residual Visual Impacts during Construction – Sung Shan New Village
The proposed visual enhancement and landscape mitigation
measures during construction are listed in Tables 9.11.5. The residual
visual impacts in the construction phase are shown in Figure 9.19.
Residual visual impacts of moderate adverse significance during construction will be
experienced by:
9.14.1.1 SSNV-VSR 2 Pedestrians using channel footbridge
The construction phase works include the removal of
the existing vegetative cover and the modification of the existing bridge
structures and retaining walls which will be difficult to effectively mitigate
during the construction stage within the relatively restricted space at this
location. As such these works will result in a moderate adverse residual impact during the construction stage.
9.14.1.2 SSNV-VSR 3 Workers and vehicles on industrial area access
road
The reconfiguration of the channel profile and
alignment will result in some tree removal to facilitate formation and
construction works with limited space for mitigating the impacts as viewed from
the adjacent access road. These works will result in a moderate adverse
residual impact during the construction stage.
Residual visual impacts of slight / moderate adverse
significance during
construction will be experienced by:
9.14.1.3 SSNV-VSR 6 Smallholdings
south of existing channel
The reconfiguration of the channel profile and alignment
will result in removal of existing grassy vegetation to facilitate formation
and construction works. Mitigation measures can help reduce these impacts but
due to the relative proximity of the VSRs there is a slight
/ moderate
adverse residual impact.
9.14.1.4 SSNV-VSR 7 Pedestrians on footbridge crossing from Sung
Shan New Village
This VSR will experience similar issues to those
for SSNV-VSR 6 above and consequently these works will also result in a slight
/ moderate
adverse residual impact.
9.14.1.1 SSNV-VSR 5 Vehicle travellers on Sung Shan New Village
access road
These transient views
will be limited by retained vegetation and the use of mitigation measures, such
as decorative hoarding to further screen the working area from views, and will
lead to slight / moderate adverse residual impact.
Residual visual impacts of slight / insubstantial
adverse significance during construction will be experienced by:
9.14.1.2 SSNV-VSR 4 Residents of properties along Sung Shan New
Village access road
The construction phase works include the localized
removal of some existing trees and vegetative cover thereby reducing the green
edge visible along a short section of the channel. Mitigation measure, such as
use of decorative hoarding, can however help reduce impacts resulting in a slight
/ insubstantial adverse residual impact.
9.14.1.3 SSNV-VSR 8 Vehicle travellers and pedestrians on channel
bridge crossing
The main impacts will arise from the loss of some
existing vegetation, although this would be viewed through retained vegetation
located beyond the extent of the site. Given the viewing distance and the
panoramic nature of the existing view the proposed works will lead to a slight
/ insubstantial adverse residual impact.
Residual visual impacts of insubstantial
significance during construction will also be experienced by:
9.14.1.4 SSNV-VSR 1 Vehicle
travellers and pedestrians on road south of Tong Tau Po Tsuen village
The views for vehicle travelers and pedestrians
will be limited and will lead to an insubstantial residual impact.
9.14.2.
Significance of
Residual Visual Impacts during Operation – Sung Shan New Village
9.14.2.1 The proposed visual enhancement
and landscape mitigation measures during operation are described in Table
9.11.5. Residual visual impacts during the operation phase are mapped in Figure 9.19.
9.14.2.2 At Day 1 of operation the
channel improvement works will be reinstated and would generally be considered
quite similar in disposition to the existing channel constructions, particularly
where natural channel bedding has been adopted as a mitigation measure and
there are general improvements to the appearance and finishes of structures to
offset other impacts.
9.14.2.3 However, mitigation
planting will still be relatively small and there will be residual visual
impacts at VSRs where large trees have been removed to facilitate the works.
and where the works have been undertaken within areas of previously relatively
unspoilt rural character. It is
noted that as compared to some of the other villages the upper parts of the
channel are relatively rural and the proposed channel works are of a relatively
larger scale. There are also no existing railings along most of the channel and
their introduction does cause a visual impact, for which the introduction of a
decorative design and channel edge shrub planting does not necessarily mitigate
in the more rural parts of the channel. Parts of the channel are also well
vegetated in the existing situation and the benefits of new greening measures
may therefore be more measured at such locations.
9.14.2.4 With the maturing of
landscape planting and screening trees, residual impacts will tend to diminish
further by Year 10 of operation. At locations where the previous condition was
a little run down and there is additional planting and a general improvement in
the level of finishes to structures, slight beneficial residual impacts may
also be anticipated. Generally,
insubstantial and beneficial impacts after mitigation would be anticipated at
Vantage Points within villages where combinations of the following are found:
·
the
existing scene is a little rundown and unmanaged,
·
there
is opportunity to introduce new tree and shrub planting as mitigation to
significantly improve the extent of greenery and soften the appearance of the
channel.
·
there
is a more urban character and context where decorative treatments on new
structures may be deemed appropriate,
·
the
engineering proposals are of a small scale or a similar scale and alignment to
the existing channel they replace,
·
Views
are more distant or of a partial / glimpsed nature such that the impacts are
less significant and small visual improvements may be deemed beneficial
relative to this baseline.
At SSNV these factors have
been assessed for all of the VSR’s and the residual visual impacts after
mitigation at both Day 1 and Year 10 at each VSR is summarized as follows:
9.14.2.5 At Day 1 of the operation phase, SSNV-VSR 3 (Workers and vehicles
on industrial area access road) will experience residual visual impacts of slight
/ moderate adverse significance
although these will be alleviated to slight adverse at Year 10 by virtue of
the maturing planting at the channel edges. Whilst views of the channel are
contained within a corridor defined by planting and adjacent property
boundaries / built structures there are views to the channel bed at this
location from the adjacent access road as the vegetation on the southern bank
is low level grass and only occasional small tree clusters are present. The
proposed alignment of the newly constructed channel undergoes minor
modification at this location where the sloping southern bank is modified to a
vertical profile whereby a few small clusters of existing tree planting are not
able to be compensated at their original location. However the majority of the
existing tree planting and larger trees are located on the northern bank and
the proposed alignment is designed to accommodate retention of these trees.
There is also space on the northern bank to accommodate some channel greening
associated with proposed current deflectors in the stream bed and to allow the
introduction of trailing edge planting to soften to the new wall structures.
This planting will take time to establish but by Year 10 it is anticipated that
the greening qualities of the existing scene could be only slightly adversely
affected as compared to the original condition. The enclosed nature of the view
and the more urban / industrial context of the location suggests that proposed
safety railings along the channel edge are compatible with the landscape
context and these can also be softened by maturing of bankside shrub planting
in the longer term. The current channel construction is also a little degraded
and it replacement with a new coherent structure is deemed a favourable aspect
in coordination with the other proposed mitigation measures.
9.14.2.6 At Day 1 of the operation phase, SSNV-VSR 5 (Vehicle
travellers on Sung Shan New Village access road) will experience residual
visual impacts of slight / moderate adverse significance although
these will be alleviated to slight adverse at Year 10 by virtue of
the maturing planting. As illustrated in Figures 9.25 and 9.26, the channel is aligned to
the roadside and so to some extent a managed appearance (OM2) is compatible
with the landscape setting, whilst the responsive design of the channel
alignment (OM03) allows the retention of the large existing trees on the
northern side of the channel. However the southern bank forms an edge to a more
rural area which is currently well vegetated with an attractive visual quality
which cannot be immediately replicated. The channel is proposed to be slightly
widened at this location with a straight sided channel replacing a sloped area
on the southern side of the channel which supported this vegetation of woody
shrubs and some small trees. Whilst creating more of an initial visual impact
the vertical side at the southern bank channel can however be mitigated to some
extent by selection of natural tone materials for the side wall construction
(OM02) whilst such vertical wall design does allow more space for the
introduction of compensatory trees planting (OM06) and channel edge greening
(OM08). In terms of trees the new planting adequately compensates for the
losses however the overall greening effect is still diminished at Day One. The
channel side railing though small in scale are also not entirely compatible
with the more rural context of this part of the channel and would be relatively
visible before planting has matured. In combination with other factors this
leads to an assessment of slight / moderate impact after mitigation at Day One.
However, over time the growth of vegetation and weathering of materials will
help blend the constructed works with their landscape setting. In particular
the growth of trailing plants at the channel edges (OM04) and the maturing of
the compensatory tree planting (OM06) and shrub planting at the channel edges
will reduce the residual impacts to Slight and Year 10.
9.14.2.7 At Day 1 of the operation phase, SSNV-VSR 6 (Smallholdings
south of existing channel) will experience residual visual impacts of slight
/ moderate adverse significance
although these will be alleviated to slight adverse at Year 10 by virtue of
the maturing planting. Whilst there are no existing trees along the southern
bank, the current view is well vegetated and the removal of this vegetation
would constitute the main impact prior to mitigation, opening up direct views
to the newly engineered channel from this close vantage point. However the
proposed channel alignment and profile are quite similar to the existing and
there is space within the works boundary to introduce mitigation measures in
the form of new tree and shrub planting at the channel edge along the southern
bank and for mitigation planting works on the proposed channel embankments and
northern channel edges. There
are large existing bankside trees visible downstream along the northern bank
and a few of the more distant of which would be lost as part of the works and
for which the stature of newly planted trees in the foreground of the southern
bank would not fully mitigate at Day 1. However, with the maturing of these
trees it is anticipated that by Year 10 the greening qualities of the existing
scene could be effectively compensated. The more rural context of this area of
the upper area of the SSNV channel is also a factor in the effectiveness of
proposed mitigation measures as the proposed safety railings along the channel
edge are less compatible with this landscape context than within more urban
settings. Whilst these would be screened to some extent by maturing bankside
shrub planting and channel edge greening measures in the longer term, a slight
residual impact is anticipated by Year 10.
9.14.2.8 At Day 1 of the operation phase, SSNV-VSR 7 (Pedestrians on
footbridge crossing from Sung Shan New Village) will experience residual visual
impacts of slight / moderate adverse significance although
these will be alleviated to slight adverse at Year 10 by virtue of
the maturing of new tree planting and channel side shrub and trailing planting
introduced as mitigation measures (OM06, OM08) and the establishment of
in-channel planting and embankment planting mitigation measures (OM07, OM05). Figures 9.28 and 9.29 for SSNV-VSR 7 (Pedestrians
on footbridge crossing from Sung Shan New Village) illustrate how the impact of construction works in
a vegetated urban fringe setting are to some extent offset by additional tree
planting and channel edge greening. Whilst the character of the scene is a
little more managed and man-made than the original condition the assessment
considers that the location is close to the boundary between an urban character
area (LCA03) and a more rural/agricultural character area (LCA04) and the
proposals would create a logical transition between these character areas where
the riverside on the rural side of this transition is well vegetated with new
tree and shrub planting to create a verdant edge condition after mitigation. Nevertheless the VSR currently
enjoys an open view of a green rural scenery and although they are small scale
elements the introduction of channel side railings is an overtly man made
element which reinforces the linearity of the channel alignment through this
rural landscape. This effect is not entirely mitigated at Year 10 resulting in
a slight residual visual impact at Year 10.
9.14.2.9 At Day 1 of the operation phase, SSNV-VSR 2 (Pedestrians
using channel footbridge) are anticipated to have insubstantial impacts and slight beneficial impacts at
Year 10. As illustrated in Figures 9.22 and 9.23 the existing condition
at this location is somewhat shabby with exposed and degraded structures
associated the deteriorated condition of the existing channel and hard surfaces
and a plethora of unmanaged vegetation. Although the river area boundary is
lined with existing trees and vegetation which provides a degree of visual
enclosure there are nearby developments on either side of the channel and as
such the landscape context is relatively urban. The proposed engineering works
involve some minor realignment of the channel and re-construction of a straight
sided channel profile at this change in the channel direction resulting in the
loss of three existing small trees and the removal of some existing in-channel
vegetation. However the larger trees aligned to the channel corridor are
retained through responsive alignment (OM03) whilst the layout incorporates a
new pedestrian footbridge alignment (OM04) which allows for the introduction of
more tree planting and channel edge shrub planting area to compensate for this
loss (OM06). The presence of existing railings along sections of the existing
channel and the more urban context of the location suggests that proposed
safety railings along the channel edge are more compatible with the landscape
context as compared to the more open and rural context of vantage points
further upstream. At Day One the addition of new tree and shrub planting (OM06)
is assessed to offset the minor impact of the decorative safety railings (OM02)
resulting in an insubstantial impact. The railings can also be further softened
by maturing bankside tree and shrub planting in the longer term. As illustrated
in Figure 9.23 the tidying up of the
area, the maturing of the new tree and shrub planting and trailing planting at
the channel walls (OM08) to soften the appearance of the built structures is
therefore considered to be an enhancement to the visual impression of the area
in the longer term resulting in a Slight Beneficial Impact by Year 10.
9.14.2.10 Of the remaining VSRs at
this site, all are considered to have insubstantial residual impact after
mitigation at both Day 1 and Year 10, including
SSNV-VSR 1 (Vehicle travellers and pedestrians on road south of Tong Tau Po
Tsuen village), SSNV- VSR 4 (Residents of properties along Sung Shan Village
access road) and SSNV-VSR 8 (Vehicle travellers and pedestrians on channel
bridge crossing). Compared to other Vantage points these are a little distant
from the proposed works and of a partial / glimpsed nature such that the
unmitigated impacts during the operation stage are deemed slight or
insubstantial. With the introduction of mitigation measures some minor
improvements are then anticipated such that the impacts would also be deemed
insubstantial after mitigation.
9.14.3.
Significance of
Residual Visual Impacts during Construction – Tai Wo
The proposed visual enhancement and landscape mitigation
measures during construction are listed in Table 9.11.6. The residual
visual impacts in the construction phase are shown in Figure 9.46.
Residual visual impacts of moderate /
substantial adverse significance during construction will be experienced
by:
9.14.3.1 TW-VSR 5 Pedestrians on narrow footpath between Tai
Wo and Cheung
Po
Residual impacts experienced by this VSR will be moderate / substantial
adverse due to the loss of
existing trees and the excavation of a new open drainage channel in close
proximity to the existing footpath within this otherwise undeveloped area.
Residual visual impacts of slight / moderate
adverse significance during construction will be
experienced by:
9.14.3.2 TW-VSR 1 Residents of Tai Wo (south east)
The main impacts will arise from the loss of some
existing vegetation and views of the excavation and construction works and
associated plant and equipment, although this would be viewed through retained
vegetation located beyond the extent of the site. Given the viewing distance
and the panoramic nature of the existing view, the proposed works will lead to a
slight / moderate adverse residual impact.
Residual visual impacts of slight adverse significance during construction will be
experienced by:
9.14.3.3 TW-VSR 3 Residents of Tai
Wo (south) and TW - VSR 4 Residents of Tai Wo (south west)
The main impacts will arise from the loss of some
existing vegetation and excavation works associated with the scheme, although
these will be relatively distant from these VSRs.
Residual visual impacts of slight adverse significance during
construction will be experienced by
these VSRs.
Residual visual impacts of Insubstantial /
slight adverse significance during construction will be
experienced by:
9.14.3.4 TW-VSR 2 Walkers on hillside water catchment drainage
channel
Owing to the elevated viewing position, there will
be views of a large extent of the scheme. However, from this distant view, the
works are very small scale and would be viewed against a backdrop of the
existing villages and other development works ongoing in the vicinity. Residual
impacts experienced by this VSR will therefore be insubstantial / slight.
Residual visual impacts of insubstantial
significance during construction will be experienced by:
9.14.3.5 TW-VSR 6 Residents of Cheung Po village (south east)
Potential impacts arise from the loss of some
existing vegetation which could marginally affect the effective existing
vegetation screening of the site from these VSRs, particularly in relation to
any taller elements such as excavation machinery deployed during the
construction stage. However, given the viewing distance and the panoramic
nature of the existing view, the proposed works will lead to an insubstantial
residual impact.
9.14.3.6 TW-VSR 7 Pedestrians on West Rail overbridge to east
of site
Potential impacts arise from the loss of some
existing vegetation which could marginally affect the effective existing
vegetation screening of the site from these VSRs, particularly in relation to
any taller features such as excavation equipment deployed during the construction
stage. However, given the viewing distance and the panoramic nature of the
existing view, the proposed works will lead to an insubstantial residual
impact.
9.14.4. Significance of Residual Visual Impacts during
Operation – Tai Wo
The proposed visual enhancement and
landscape mitigation measures during operation are described in Table 9.11.6.
Residual visual impacts during the operation phase are mapped in Figure 9.46. At Day 1 of operation, the drainage improvement works will be completed
and would generally be considered to be small scale and low profile is addition
to the landscape. Whilst the open channels are narrow, features sections towards
the village areas are also buried below ground, further reducing the potential
for visual impact. However, mitigation planting will still be relatively small
and there will be residual visual impacts at some VSRs where larger trees have
been removed to facilitate the works. With the maturing of landscape planting
and screening trees, residual impacts will tend to diminish further by Year 10
of operation.
By Day 1 of the operation phase TW-VSR 5
(Pedestrians on narrow footpath between Tai Wo and Cheung Po) will experience residual visual impacts of slight
/ moderate adverse significance although these will be alleviated to
slight at Year 10 by virtue of the maturing planting. At Day 1 of the
operation phase, TW-VSR 1
(Residents of Tai Wo south east) and TW-VSR 3 (Residents of Tai
Wo south) will
experience residual visual impacts of slight adverse significance
although these will be alleviated to insubstantial at Year 10 by virtue
of the maturing planting. The remaining four VSRs at this village will have insubstantial
residual impact at both Day 1 and Year 10.
9.14.5. Significance of Residual Visual Impacts during
Construction – Lin Fa Tei
The proposed visual enhancement and landscape
mitigation measures during construction are listed in Table 9.11.7. The
residual visual impacts in the construction phase are shown in Figure 9.80.
Residual visual impacts of moderate /
substantial adverse significance during construction will be
experienced by:
9.14.5.1 LFT-VSR 1 Vehicle
travellers and pedestrians on Kam Sheung Road
The construction phase works include the removal of
some of the existing roadside trees lining the road. As such these works will
result in a moderate / substantial adverse residual impact.
9.14.5.2 LFT-VSR 9 Pedestrians on
riverside footpath to south west of Lin Fa Tei
The construction phase works include the removal of
existing vegetation within the channel and formation works to configure the new
channel profile. Given the close proximity of the VSR and the rural nature of
the setting, these works will result in a moderate / substantial adverse residual impact.
Residual visual impacts of moderate adverse
significance during
construction will be experienced by:
9.14.5.3 LFT-VSR 5 Residents of
Lin Fa Tei Riverside
Whilst there are a few existing trees to be
affected at this location, the constricted space and proximity of the public
space surrounding the channel will also limit the potential of construction
stage mitigation measures. As such these works will result in a moderate
adverse residual impact.
9.14.5.4 LFT-VSR 6 Vehicle
travellers and pedestrians at channel crossing in Lin Fa Tei
Whilst there are no existing trees to be affected
within this view, the constricted space and proximity of the public space
surrounding the channel will also limit the potential of construction stage
mitigation measures. As such these works will result in a moderate adverse residual
impact.
9.14.5.5 LFT-VSR 8 Residents of
Lin Fa Tei (South West)
The close viewing distance to the necessary formation
and construction works will be difficult to significantly mitigate and these
works will result in a moderate adverse residual impact during the
construction phase.
Residual visual impacts
of Slight / Moderate adverse significance during construction will be
experienced by:
9.14.5.6 LFT-VSR 2 Pedestrians on
Footpath between Lin Fa Tei and Kam Sheung Road
Given the narrow site
works area, the views for pedestrians cannot be significantly mitigated
including the installation of temporary noise barriers of around 3m height.
However, given the disturbed and slightly shabby nature of the immediate
surroundings, the proposed works will lead to a Slight / moderate adverse residual impact for this
VSR during the construction stage.
9.14.5.7 LFT-VSR 3 Residents and
pedestrians at Lin Fa Tei Village Gateway
The construction phase
works will include use of construction plant and machinery at this open hard
surfaced urban space which includes the installation of temporary noise
barriers of around 3m height to help mitigate noise impacts at adjacent
properties. However, since the site is at the edge of this area, the use of
screen hoarding and other mitigation measures can be partially effective. As
such These works will result in a Slight
/ moderate adverse
residual impact during the construction Phase.
Residual visual impacts
of slight adverse significance during construction will be experienced
by:
9.14.5.8 LFT-VSR 4 Vehicle
travellers and pedestrians on Shui Tsan Tin access road
Given the viewing
distance, the intermittent intervening vegetation and the panoramic nature of
the existing view, the proposed works will lead to a slight adverse
residual impact.
Residual visual impacts of slight / insubstantial
adverse significance during construction will be
experienced by:
9.14.5.9 LFT-VSR 7 Residents of
Lin Fa Tei (Central)
Given the viewing distance, the intervening
vegetation and the panoramic nature of the existing view, the proposed works
will lead to slight / insubstantial adverse residual
impact.
9.14.6.
Significance of Residual
Visual Impacts during Operation – Lin Fa Tei
The proposed visual
enhancement and landscape mitigation measures during operation are described Table 9.11.7. Residual visual impacts
during the operation phase are mapped in Figure 9.80. At Day 1
of operation, the channel improvement works will be reinstated and particularly
at LFT-VSRs 1-3, the new construction areas would generally be considered quite
similar in disposition to the existing channel constructions. Natural channel
bedding and general improvements to the appearance and finishes of structures
can also mitigate some of the impacts of the works. However, mitigation
planting will still be relatively small and there will be residual visual
impacts at VSRs where larger trees have been removed to facilitate the works.
With the maturing of landscape planting and screening trees, residual impacts
will tend to diminish further at Year 10 of operation. At locations where there
is additional planting and a general improvement in the level of finishes to
structures, slight beneficial residual impacts are also anticipated.
9.14.6.1 During the operation phase, the predicted residual
impacts for LFT-VSR
9 (Pedestrians on riverside footpath to south west of Lin Fa Tei) would be reduced from moderate in Day 1 to slight / moderate in Year 10 after mitigation. At LFT-VSR 1 (Vehicle
travellers and pedestrians on Kam Sheung Road), since the main impact is
removal of trees, the growth of new trees between Day 1 and Year 10 would allow
the residual visual impacts
in the operation phase to be reduced from slight/moderate to insubstantial at Year 10. Similarly, the reinstatement of the
channel at LFT-VSR
8 (Residents of Lin Fa Tei (South West)) can be reduced from slight to insubstantial after 10 years of tree
and vegetation growth.
Of the remaining VSR’s at this site, three
locations will have insubstantial residual impact at both Day 1 and Year 10 (LFT-VSR
2, LFT-VSR 4 and LFT-VSR 7). For LFT-VSR 5 and LFT-VSR 6, owing to the
sensitivity of the locations the unmitigated impacts are deemed moderate,
however owing to the slightly rundown nature of the existing visual environment
and the potential for improvements to enhance this communal space the effect of
improvements to existing structures, use of decorative railing at the channel
edge and the addition of tree and shrub planting to blend the channel into the
surroundings and soften views of existing structures is considered to represent
visual improvement. A similar potential for beneficial improvements is also
noted at LFT-VSR 3. As such, owing to the improved nature of the channel
structures and introduction of additional planting, mitigation measures at
these three VSR’s are deemed to generate slight beneficial impacts at Day 1 and, after maturing of the
additional, planting at Year 10, these would be considered slight / moderate beneficial.

Significance of
Residual Visual Impacts during Construction – Ha Che
The proposed visual enhancement and landscape
mitigation measures during construction are listed in Table 9.11.8. The
residual visual impacts in the construction phase are shown in Figures 9.119 to
9.120.
Residual visual impacts of moderate /
substantial adverse significance during construction will be
experienced by:
9.14.7.1 HC-VSR 4 Residents of
village houses at south of Shui Kan Shek
The construction phase works include the removal of
some existing trees at this village gateway site. These works will result in a moderate
/ substantial adverse residual impact at the construction stage.
9.14.7.2 HC-VSR 5 Vehicle
travellers and pedestrians on Shui Kan Shek access road
The construction phase works include the removal of
some existing trees at this village gateway site. These works will result in a moderate
/ substantial adverse residual impact at the construction stage.
Residual visual impacts of moderate adverse
significance during
construction will be experienced by:
9.14.7.3 HC-VSR 6 Residents of
village houses at north of Chuk Hang
The proximity of these houses to the channel and
their slight elevation looking down into the channel makes effective mitigation
difficult at the construction stage. In addition, the removal of some trees
will result in a moderate adverse residual impact.
9.14.7.4 HC-VSR 7 Vehicle
travellers and pedestrians on Fan Kam Road
Whilst some larger trees at the roadside can be
retained, further trees within the existing channel will need to be removed and
will result in a moderate adverse residual impact at the construction
stage.
9.14.7.5 HC-VSR 8 Residents of Ha
Che bordering Fan Kam Road
Whilst some trees can be retained, some individual
existing trees near the channel which frame entrance driveways to houses will
need to be removed and will result in a moderate adverse residual impact
at the construction stage.
Residual visual impacts of slight / moderate
significance during construction will be experienced by:
9.14.7.6 HC-VSR 3 Pedestrians on
footpath from Fan Kam Road to Shui Kan Shek
The construction phase works include the removal of
some existing trees along the channel. These works will result in slight /
moderate adverse residual impact
Residual visual impacts of slight adverse significance
during construction will be experienced by:
9.14.7.7 HC-VSR 1 Pedestrians on
industrial area access path
There will be some impact on existing vegetation
within the channel although views to the site can be readily mitigated by the
erection of a short section of decorative screen hoarding. As such, the
proposed works will lead to a slight adverse residual impact.
9.14.7.8 HC-VSR 9 Residents of Ha
Che (south east)
There will be some impact on existing trees and
vegetation along the edges of the channel resulting in a slight adverse
residual impact.
Residual visual impacts of insubstantial significance
during construction will be experienced by:
9.14.7.9 HC-VSR 2 Residents of
village houses north of Shui Kan Shek)
The views are localized and can be readily
mitigated by the erection of a short section of decorative screen hoarding. As
such, the proposed works will lead to an insubstantial residual impact.
9.14.8.
Significance of
Residual Visual Impacts during Operation – Ha Che
The proposed visual
enhancement and landscape mitigation measures during operation are described Table 9.11.8. Residual visual impacts
during the operation phase are mapped in Figures 9.119 to 9.120. At Day 1 of operation, the channel improvement works will be reinstated
and particularly at HC - VSRs 1-3, the new construction areas would generally
be considered quite similar in disposition to the existing channel
constructions. Natural channel bedding and general improvements to the
appearance and finishes of structures can also mitigate some of the impacts of
the works. However, mitigation planting will still be relatively small at Day 1
and there will be residual visual impacts at VSRs where larger trees have been
removed to facilitate the works. With the maturing of landscape planting and
screening trees, residual impacts will tend to diminish further by Year 10 of
operation. At locations where there is additional planting and a general
improvement in the level of finishes to structures, slight beneficial residual
impacts are also anticipated.
9.14.8.1 During the operation phase, the predicted residual
impacts for HC-VSR
4 and HC-VSR 5 would be slight / moderate at Day 1, reducing to slight beneficial at Year 10 after the growth of compensatory tree
planting. For HC-VSR 4 and HC-VSR 5, since
the area is a gateway to a village / residential area the addition of
decorative railings, the formation of a new vehicular bridge and tidying up of
drainage structures and the introduction of amenity tree and shrub planting
associated with the works is deemed to be appropriate and compatible to this
location and therefore mitigation measures could have potential for improvement
as compared to the existing scene. However, since there will be removal of some
established trees, particularly for VSR4, the impacts are considered Slight /
Moderate adverse at Day 1 with the effectiveness of mitigation as a Slight
Beneficial Impact arising only on maturing of the tree planting at Year 10 to
compensate for the stature of some of the lost trees. Similarly at HC-VSR 6, since the main
impact is removal of trees the growth of new trees between Day 1 and Year 10
would allow the residual visual
impacts in the operation phase to be reduced from slight/moderate adverse to slight
/insubstantial adverse at
Year 10.
9.14.8.2 The reinstatement of the channel at HC-VSR 7 can be reduced
from slight adverse to slight
/ insubstantial adverse after 10 years of tree and vegetation growth
whilst slight adverse residual impacts at Day
1 at HC-VSR3 can be transformed to slight beneficial after 10 years growth of
the mitigation planting scheme.
9.14.8.3 Residual Impacts at Day 1
and Year 10 during the operation phase are deemed insubstantial at HC-VSR 2 and HC-VSR
9. Of the remaining VSRs at
this site, HC-VSR
1 will have slight beneficial impacts at both Day 1 and Year 10 owing to the improved
nature of the structures and introduction of additional planting. The remaining
location (HC-VSR 8,) is deemed to have slight
/ moderate adverse and slight/ insubstantial adverse impact in Day 1 and Year 10.
There are no current planned major
public projects in these four village locations. Therefore, given the
above, it is anticipated that there will be no significant long term cumulative
landscape and visual impact on Landscape Resources, Landscape Character and
visual amenity of VSRs.
