Station Design Considerations and Approach
This section describes
legislation and guidelines that have been reviewed in the Landscape and 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 has been
based on the criteria and guidelines stated in Annexes 10 and 18 of the EIAO-TM
and covered in the scope outlined in section 3.4.10 of the EIA Study Brief. The
assessment identifies potential landscape and visual impacts that would occur
during the construction and operational phases of all above-ground structures
proposed under the proposed SIL(E) project [hereinafter referred to as SIL(E)]
including the proposed viaduct section, railway bridge, and ventilation shafts
/ buildings, recommends landscape mitigation measures to alleviate the impacts;
and identifies residual effects apparent after mitigation.

General
The preparation of the
LVIA is based on the EIAO GN No. 8/2002 “Preparation of Landscape and Visual
Impact Assessment under the EIAO” for evaluation of the proposed SIL(E). Section 2 describes the details of the
Project and this LVIA section also provides a summary. The methodology for the
LVIA is described in the following sections.
6.3.1.2
Review of
Planning and Development Control Framework
A review of the
existing planning studies and documents has been undertaken as part of the
baseline study 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. This review
considered Outline Zoning Plan numbers including S/H4/13 Central District ,
S/H24/6 Central District (Extension), S/H11/15 Mid-levels West, S/H14/10 The
Peak Area, S/H15/26 Aberdeen and Ap Lei Chau, S/H10/15 Pok Fu Lam and S/H17/11
Shouson Hill & Repulse Bay. Compatibility of the proposed works to the
planned developments either within or adjacent to the Study Area are also
considered in terms of landscape and visual impacts.
6.3.1.3
Landscape
Baseline Review and Impact Assessment
The assessment of the
potential 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) Study Area
has been undertaken to include all areas within 100 m of the site boundary 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 identity.
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 Study 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 (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) of the LRs /
LCAs;
¡
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 significance
threshold is derived from the following matrix:

6.3.1.4
Tree
Survey Methodology
To minimize conflicts with
existing vegetation a preliminary tree survey in accordance with ETWB TCW No.
3/2006, ‘Tree Preservation’ has been undertaken to inform the potential tree
impact assessed in this LVIA as a result of the proposed works. This tree
survey involves the identification of individual trees within the proposed
works area. The survey includes individual tree species, sizes, health
condition, form, and amenity value and their treatment as a result of the
implementation of proposed works. The information contained in this part of the
report has been abstracted from the tree survey undertaken by the consultants
for each component of the proposed scheme.
This existing tree data
allows the fine tuning of the detailed design for the proposed works and
ensures that any significant trees including potential old and valuable trees
or rare or protected tree species, where possible, be protected in current
location or through transplantation during both the construction and
operational phases of the Project.
6.3.2.1
Visual
Baseline Review and Impact Assessment
The assessment of the
potential 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 an Visual Envelope (VE) which
includes all areas from which the proposed works can be seen, or the area forms
the view shed formed by natural / manmade features such as existing ridgelines,
built development and for example areas of woodland / large trees. Within the
VE, Zone of Visual Influence (ZVI) is identified to demonstrate the visibility
of the proposed works. This is achieved through a combination of detailed
walkover surveys, and desk-top study of topographic maps and photographs, and
preparation of cross-sections to determine visibility of the improvement works
from various locations.
The baseline survey of
all views towards the proposals is undertaken by identifying:
¡
The VE and
ZVI as have been described above and may contain 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 visual envelope 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 of
intrusion on the visual amenity and quality of life;
¡
View from
workplaces – less sensitive than above due to 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. 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; and,
¡
Degree of
visibility.
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;
¡
Reversibility
of change; and
¡
Night
glare effect.
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 to 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 blocked the views of VSRs /
project nature is fairly compatible to existing visual context / works area
located in the middle ground of the visual context and not immediately adjacent
to VSRs 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 to existing visual context / works area located in distant to VSRs /
permanent impacts and duration of construction impacts is short/ Irreversible
change or temporary change of view; and
¡
Negligible:
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.

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. 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 alignment and their associated
above-ground 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 etc) to compensate for
unavoidable adverse impacts and to attempt to generate potentially beneficial
long-term 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 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 of change, which the project will cause to the
LRs/LCAs and the visual context of VSRs taking into account the beneficial
effects of the proposed mitigation and the sensitivity of LRs/LCAs and VSRs.
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 of 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 6.2 below.
Table 6.2: Residual Impact
Significance Threshold Matrix
|
Residual Impact |
Description |
|
Beneficial |
The project will complement the landscape and visual character of its setting, will follow the relevant planning objectives and will improve overall and visual quality |
|
Acceptable |
There will be no significant effects on the landscape, no significant visual effects caused by the appearance of the project, or no interference with key views. |
|
Acceptable with mitigation measures |
There will be some adverse effects, but these can be eliminated, reduced or offset to a large extent by specific measures. |
|
Unacceptable |
The adverse effects are considered too excessive and are unable to mitigate practically; |
|
Undetermined |
Significant adverse effects are likely, but the extent to which they may occur or may be mitigated cannot be determined from the study. Further detailed study will be required for the specific effects in question. |

6.4 Project Summary for LVIA
The following project summary is based on Section
2. Figure 1.1 shows the alignment for the proposed SIL(E),
its associated above ground and underground works are illustrated on Figures 2.6.1 to 2.6.12.
The proposed South Island Line (East) - the
Project, will comprise the following:
¡
Approximately
¡
Construction
of stations including South Horizons (SOH), Lei Tung (LET), Wong Chuk Hang (WCH), Ocean Park (OCP) and Admiralty (ADM). WCH and OCP Stations are designed to be elevated
along the viaduct alignment while SOH, LET and ADM Stations are designed to be
underground associated with above-ground station entrances and exits, vent shafts or plant
building and will be constructed by either drill-and-blast or cut-and-cover
tunnelling method.
¡
Construction
of tunnels by drill-and-blast, mining and cut-and-cover method. Based on the
current design, tunnel sections from Admiralty to Nam Fung Portal and from Lee
Nam Road to Ap Lei Chau Drive will be constructed by drill-and-blast tunnelling
method, whilst tunnel sections from Ap Lei Chau Drive to the portal at the
southern side of Aberdeen Channel Bridge will be constructed by mining and cut
and cover tunnelling method;
¡
Construction
of the tunnel
portals southern side of
¡
Construction
of the ventilation
shafts along the alignment associated with the proposed stations, at
¡
Construction
of a depot at the ex-Wong
Chuk Hang Estate site.
¡
Construction
of viaduct section from
¡
Construction
of a railway bridge alongside of Ap Lei Chau Bridge across the Aberdeen Channel.
¡
Provision
of site offices, areas for construction material storage, construction shafts,
barging points and magazine site during construction.
¡
Operation
of the railway system and the depot.
The engineering design of the SIL(E) corridor
is still being developed and hence the construction methods for individual
sections mentioned in the above sections are subject to review.
6.4.2.1
Admiralty
Station Extension and Associated Facilities
ADM station will become a major interface
station for the SIL(E), the future SCL and the existing Island Line (ISL) and
Tsuen Wan Line (TWL). The works will include an extension east of the existing
ADM station to accommodate interchange concourse, necessary circulation areas and
plant rooms.
Efforts have been taken in minimizing potential
landscape and visual impacts through reducing the land-take for the provision
of aboveground facilities during design stage.
However, the extent of works area and design of ADM station and associated
operation facilities are determined by the following physical and design
constraints to accommodate enough working areas for constructing tunnel section
from Admiralty to Nam Fung portal as well as the necessary space for railway
operation, station concourse, passenger circulation, plant room and ventilation
structures. These constraints as well as the design intent of the ADM station
extension are described in details in Appendix 6.3.
The extension of ADM Station is physically
constrained by the existing Harcourt and Rodney underground car parks formed a
barrier negating additional loading above the car parks and undermining of the
structure below the car parks; existing TWL and Harcourt Road limited expansion
of the station footprint and this is further complicated by the geological
conditions; existing electrical sub-station sit on top of the TWL tunnel box,
and; the ISL track and its ventilation and smoke extraction structures
currently located in the centre of Harcourt Garden and also foundation of
commercial buildings adjacent to Harcourt Garden. All these existing above
ground or underground structures should be maintained and hence determined
proposed works area and location of the extension of ADM station for the
SIL(E).
Design constraints are also considered to meet
the operation and safety requirement for future passenger. These include
pedestrian circulation between existing ISL and TWL, the SIL(E) and planned SCL
underground platforms and station concourses and accommodation of lift shafts,
escape/ access stairs to facilitate efficient and direct vertical connectivity.
In addition, certain station components should be put at grade or above ground
to meet the FSD or functional requirements; these components include electric
traction, power equipment rooms, transformers and associated plant rooms. Such
rooms are proposed on the perimeter of the building where possible to afford
direct access and efficient ventilation. Headroom requirement within these
plant rooms varies between 4.5m to 7.0m.
Tunnel ventilation fan rooms, shafts and
ventilation structures for the planned SCL previously proposed to the north of
Ventilation facilities provide routes for air
exchange and in the emergency events such as fire and smoke control and inevitably
there is a requirement for ventilation structures above the station building.
The requirement for these is further exacerbated by smoke exhaust segregation
parameters defined by FSD. The ventilation requirements have been significantly
increased as introduced by FSD that all smoke zones within the building are to
be provided with independent smoke extraction system. The detailed design
consultants (DDCs) have been carefully considered the form and mass of the new
ventilation shafts for the SIL(E) and planned SCL and the integration of
existing ventilation shafts within such a small and constrained site. The DDCs
have developed the design aesthetic according to practical requirements such as
separation distance. It should be noted that efforts were made during the
development of the design to unify and unite the ventilation shafts to achieve
a conjoined solution. The location of the ventilation shafts is determined by
the shafts serving them within the building. Transfer zones above ground level
which would increase the mass of the ground floor have been avoided where
possible, resulting in most of the ventilation shafts being located directly
above the vertical ducts within the building.
Based on the above physical site constraints
and station design requirement, alternative massing and design of Harcourt
Garden are carefully studied and carved out until the most preferred design
option is reached. The DDCs has identified design opportunities to ensure that
the design of future
Headroom required for the proposed plant rooms
at ground level in response to the FSD requirements determined the structural
roof levels of the station building. These varying levels across the roof
dictated optimum locations for planting and hard landscape to make the best use
of available soil depths whilst restricting the overall height of the landscape
deck. Resulting from the minimum height required to accommodate ground level
plant rooms, proposed finishing level of the top of terrace gardens/ landscape
deck is now similar to the level of existing footbridge connecting to the site.
It was therefore deemed appropriate to use the landscape deck to replace the
footbridge across the site. This becomes advantageous and allows for direct
access via the footbridge to surrounding developments, including
The landscape design approach to the
re-provision of
The aesthetic
appearance of railway and operation facilities within the Garden will utlise a
modern architectural approach to fit into existing commercial landscape context
and integrate with new modern park design that would create a new gathering
place for both local neighbourhoods and visitors. The
vent shafts will be clad in a palette of natural
materials to break up the massing and provide appropriate scale of
finish due to facing outwards, or inwards. Louvers, trellises and screens will
be aluminium. In line with the design objectives, the adopted design solution
serves to minimise the volume, visual mass and height of the vent shafts. At the interface between the low level garden
and the elevated landscape deck, an iconic structure in a form of a slender
clock tower is located alongside the grand staircase connecting the two levels.
The clock tower is the highest structure within the garden and will be
perceived as the icon of the future
The design team have capitalised on the
opportunities for connectivity with the footbridges, and provided garden
facilities directly accessible to a greater number of public. This has
effectively maximised the area, and increased the facilities available to the
users of

structures and associated plant rooms are necessary to be located above ground.
The ventilation shafts/ plant buildings along the alignment at
Having considered
the operational requirement, direct vehicular access to the building frontage
is always required and exhaust openings should be clear from all obstacles that
would limit tree planting opportunities right in front of the building. In
addition, wider hard paved frontage is also required for vent building at
6.4.2.3
WCH Depot
WCH Depot is bounded by proposed WCH Station to
the north, Nam Long Shan and Police School Roads to the east, south and west.
The extent of footprint of the depot is determined by the area required for the
proper depot operation including the track arrangement requirements, the EVA
layout in compliance with FSD requirement as well as the accommodation
providing all necessary operation within the depot. Having considered site
constraints, the depot will be located diagonally which is only long enough to
accommodate two number of trains back to back in a single track and fulfils the
overrun requirements and track radii. Any adjustment of the depot footprint
will have significant impact to the depot capacity and operation. Uniform site
level at about +15mPD is also required to enable connectivity of the depot with
the mainline and thus the existing site has to be lowered and reformed by up to
approximately 4m. Given the design requirement above, the majority of existing trees in the Wong Chuk
Hang Estate are not feasible to be retained in current location with
exceptional of a few of them which are good candidates for transplantation. In
addition northern portion of Nam Long Shan and Police School Roads are required
to be widened to meet the future traffic needs upon completion of WCH Station,
that is another reason why majority of existing trees on the pavement or at the
periphery of Wong Chuk Hang Estate are not able to be retained in their current
locations.
The visual appearance of the depot is carefully
studied to cater the operational and ventilation requirement as well as to
minimise the visual impact at both street and elevated levels. The massing, building height profile and
façade treatment of the Depot are considered in the views of VSRs located in
proximity or in distance. Given that existing and widened footpath surrounding
the Depot will be congested with underground utilities, new street trees would
be planted where space allows adjacent to the preserved ones to provide
continuous greening along the depot façade and create a shaded walking environment
for pedestrians. The depot façade treatment would be largely concrete finished
with greening measures such as green wall to soften the building edge at where
technically feasible and the louvers would not be obstructed. These planting
proposals are illustrated in Figures 6.9.13 and 6.9.14.
6.4.2.4
Viaducts and
The alignment and appearance of these above
ground structures are carefully considered to meet the operation and structural
requirement connecting the railway section from Nam Fung Portal to Ap Lei Chau.
Their forms, finishes and landscape proposals are designed to minimise visual
intrusion and building mass. The following design measures have been taken at
detailed design stage to improve the visual appearance of the viaduct to
alleviate the potential visual and landscape impact in balance with operational
and structural requirement:
¡
Majority
alignment utilises single viaduct (twin track) single pier design instead of
twin viaduct (two separate single track) with twin piers. This track
arrangement reduces the visual mass;
¡ Given the operational requirements, sections of
viaduct needed to be refined. These include multiple tracks at varying levels
are needed at the entry to the depot to the east of WCH Station, the standard
pier arrangement cannot be used due to the presence of the Staunton Creek
Nullah and the box girders would need to be carried on portal frames. Both the portal posts and the lintel have been
shaped to reduce their apparent form and disguise the functional appearance;
¡
Box girder
structural form of the viaduct has been adopted to reduces the number of
different structural arrangements required along the alignment;
¡
An oval
section pier to support the viaduct has been selected to give a more slender
and elegant appearance;
¡
The extent
of works has been minimised to preserve existing trees as far as possible, it
would be achieved through fine tuning of the viaduct column location. For
example, existing Old and Valuable Tree and tree with a DBH over 1M in the
vicinity of
¡ The affected area will be reinstated with
greening measures. Tree planting will be maximised where space allows and
technically feasible, otherwise other greening measures such as shrub and
climbing plants will be considered to soften the
appearance of the columns. Upon the full establishment of the greening measures
it is anticipated to form continuous green corridor and green backdrop for the
alignment.
Noise barrier or semi-enclosure is required
along the viaduct and
Regarding to
The physical and design constraints,
operational and structural requirement mentioned above determine basic shape of
the above ground structures for SIL(E). Based on this design framework, the
appearance of structures are designed with responsive approach to make better
integration with the local context and considered as optimal solution to
minimise the potential visual and landscape impact in balance with constraints.
These schemes form the basis of this assessment.

Ocean Park Station is set within a hard
landscaped road network serving
The rail level at the station is dictated by
the need for the viaduct to pass over
Given the limitation of land take, site
constraints and operation requirement, tree planting will be accommodated at
entrance areas where the pedestrian circulation would not be obstructed.
Vertical greening is also proposed on stair bookends of the station and
on the ground level park-and-ride wall. This planting proposal is
demonstrated on Figure 6.10.11.
6.5 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 context and to help to determine if the
project fits into the wider landscape context. The assessment does not consider
all of the areas zoned on the OZP but focuses on only those affected by the
proposed works. The locations of these
areas are shown on Figures
6.1.1 to 6.1.5. This review
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
potential degradation of the landscape setting of an area which might affect
the viability of it’s 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 shown on the following Outline Zoning Plans:
¡
S/H4/13
Central District;
¡
S/H24/6
Central District (Extension);
¡
S/H11/15
Mid-levels West;
¡
S/H14/10
The Peak Area;
¡
S/H15/26
Aberdeen and Ap Lei Chau;
¡
S/H19/10
¡
S/H10/15
Pok Fu Lam;
¡
S/H17/11
Given most of the
alignment will be largely constructed in the form of tunnel by drill and blast tunnelling
method, for the large part the construction works will be undertaken
underground with no physical impact to existing topography and structures above
ground. Therefore the proposed works have no implication on existing or planned
designations as shown in OZPs S/H24/6 Central District (Extension), S/H11/15
Mid-levels West and S/H14/9 The Peak Area. The main areas that would be
physically affected by construction of proposed elevated or above ground
structures include the proposed viaduct, bridge section, ventilation shafts and
tunnel portals, some stations or tunnel sections constructed using cut and
cover methods; and temporary works areas including barging points and magazine
site where there is encroachment to individual zonings. The majority of the
proposed works will not directly affect the existing land uses, with exception
of the following:
¡
Open Space
(O) Zones at Admiralty, Wong Chuk Hang and Ap Lei Chau – Open spaces such as Hong Kong Park, Harcourt
Garden will be in conflict with the tunnelling works and construction of
ventilation shafts. Open spaces to the north
of Ap Lei Chau Bridge and at the periphery of
¡
Some
proposed slope works will encroach on the
Green Belt (GB) zones located to the north of the Aberdeen Tunnel Portal, to the west of Lei Tung Estate, to the east of
Lee Nam Road adjacent to South Horizons
and adjacent to the St. Mary Home for the Aged and Holy Sprit Seminary; and Sham Wan Towers.
¡
Excavation
works for the ADM and SOH Stations
will encroach on the periphery of the Commercial Zones (C) located to the west of
¡
Residential
Group A (R(A)) Zone –The SOH Station will
encroach on
the zoning containing South
Horizons.
¡
Comprehensive
Development Area (CDA) Zone – The former Wong Chuk Hang Estate site will be redeveloped for WCH Station and a railway depot.
¡
Government,
Institution or Community (GIC) Zones – The ex-Canadian Hospital Site will be required for construction of the tunnel box and Nam Fung portal / ventilation
building. The proposed viaduct above Staunton Creek Nullah will encroach on the periphery of the

The proposed magazine site
located to the east Chung Hom Shan at
abandoned quarry site will encroach on the area zoned as Other Specified Uses (Composite Signals Organization Station
Complex) (OU).
Only the vehicular access
and small portion of proposed barging point at
The section of
alignment between Ap Lei Chau Bridge and Nam Fung Portal is designed in the
form of viaduct and elevated stations (WCH and OCP) with above ground railway
depot at Wong Chuk Hang. Therefore the existing industrial, institutional and
infrastructure landscape setting alongside the alignment would potentially be
affected. Given most of the viaduct alignment follows the existing engineered
nullah, the proposed works will be relatively compatible with existing landuse
planning designations. Although a small proportion of GB zone to the south of
Heung Yip Road and the nullah will be required for construction of viaduct, the
change of landscape setting from a landuse planning perspective would be
acceptable with mitigation measures such as responsive design of engineering
structures and planting adjacent to the viaduct. The impact on the GB zone will
be largely alleviated through responsive engineering design to minimise the
impact to existing trees and provision of new tree planting on the disturbed
area.
In addition to the
review of OZP, the proposed works area to the north of

¡
A sustainable transport system and comprehensive pedestrian linkages to

¡
Harmonizing the design of
utility buildings and infrastructure with the waterfront setting
Given the above summary
and detailed review in Table
6.3, the proposed works with mitigation measures including responsive
building and structural design and new tree planting adjacent to the built
structures largely fit within the planning and development control framework
and can be integrated with the future outlook of the urban and urban fringe
landscape context. Given that any proposed scheme/ works authorised under
Railway Ordinance shall be deemed to be approved under the Town Planning
Ordinance, no landuse review is required on the OZPs. In addition, the works
areas of barging points and magazine site are temporary in nature, again no
landuse review is required for the respective sites.

Given that the site will be comprehensively redeveloped with the proposed railway facilities and the potential residential and commericial components of the development above the depot. the proposals are considered to be tolerable to the zone’s planning intention. The potential impacts on the landscape setting of the site and the immediate environs will be minimised through the responsive design of depot facilities. In addition new street tree planting will be accommodated at where space allows, mitigating potential impacts to existing trees and soften the form of the proposed structures. Given the proposed works with mitigation measures are thus considered to be tolerable to the planning intention. |
|
6. Green Belt (GB) |
This zone encompasses the existing vegetated slopes to the south of the engineered nullah. It forms a narrow linear remnant of the area used for the construction of the nullah and the utility developments to the south. The planning intention of this zone is to define the limits of urban and suburban development areas using natural features, to contain urban sprawl and provide passive recreational outlets. |
Some sloping area adjacent to the nullah will be
acquired to accommodate the footing for the viaduct leading to the proposed 1 ha / 3ha (30%) Magnitude: Intermediate |
Potential impacts will be limited as the proposed works will occupy a relatively small portion of this zone, an area characterised by existing engineered slopes which was originally formed during the development of the existing utilities to the south. The vegetation on the disturbed area will be reinstated with woodland planting providing integration with the wooded area to the west. Given these factors the proposed works with mitigation measures are thus considered to be tolerable to the planning intention. |

roadside amenity areas and on pavement, 1,966
slope trees, approximately 1,125 Leucaena leucocephala (銀合歡), undesirable species, and 107 dead trees are
found in the survey. A broad brush tree survey undertaken
by Detailed Design Consultants of the Project (hereafter DDCs) is enclosed in Appendix 6.1 Tree
Assessment Schedule and 6.2 Tree Survey Plans.
The existing trees with a DBH of over 500mm, over 1M and Registered OVTs are
highlighted in the tree survey plans.
Photographic records of OVTs within the survey boundary are shown in Figure 6.2.18. These important landscape resources are
considered to be preserved in-situ or through transplantation during the
development of railway works and their final treatment will be assessed during
the detailed design stage. During detailed design stage tree felling
application will be prepared and circulated to the relevant government
departments for approval. The majority of these trees are located at the
roadside along the existing infrastructure corridors while a lesser number of
trees within the Study Area are located on remnant natural or engineered slopes
adjacent to Staunton Creek Nullah and the amenity trees located within the
existing parks, gardens and sitting out areas. Registered OVTs and few protected

addition to those rare and/or protected tree identified in the tree survey,
some undersized rare and/or protected tree, shrub or herb, which have local or global
conservation interest, are identified in the wider study context of Section 4 ecological
assessment. As these plants are undersized plant, shrub or
herb, they are not contained in the tree survey. Their locations refer to Figures 4.6, 4.8 and 4.9.
In addition to
registered OVTs, rare and/or
protected species, the tree survey also identified approximately ten
existing trees which have a DBH over 1M. Two of them are located in ex-Canadian
Hospital Site (shown on Figure A6-903-2),
one on sloping area to the north of
The important
determinants of the landscape character within the Study Boundary include the
key landscape resources (LRs) including a combination of natural woodland on
upland areas, mixed woodland planting on remnant and lower hill slopes between
existing development and infrastructure, plantation alongside the key roads and
nullah, plantation woodland and amenity trees within the parks and open spaces,
plantation and tree planting within individual developments; modified stream
courses and water bodies, major roads and infrastructure; and the main
concentrations or massing of the built environment. These LRs are shown on Figures
6.2.1 to 6.2.16. The following LRs
have been identified within the Study Area and Table 6.4
provides an assessment of the sensitivity of each of the identified LRs:
LR1 Major Roads and Highways – The major roads and highways contained within the Study Area include
Queensway, Harcourt Road, Aberdeen Tunnel Road and Portal, Wong Chuk Hang Road,
Heung Yip Street, Ap Lei Chau Bridge Road, Lee Nam Road and Yi Nam Road. This

LR2.19
LR3 Natural Woodland –
This LR includes the secondary woodland coverage and woodland stands of the
Mid-levels; and the upland areas of central Hong Kong Island including Mount Gough,
Magazine Gap, Wan Chai Gap and Mount Cameron, on upland areas surrounding
Aberdeen Reservoirs within the Aberdeen Country Park, and on the upland areas
of Yuk Kwai Shan and Nam Long Shan in the southern part of Hong Kong Island.
The majority of this resource although secondary or plantation remains
untouched by the urbanization of Hong Kong Island, hence it is regionally
significant in terms of its contribution to the landscape context and sensitive
to small changes. Therefore the sensitivity of LR3 is considered to be high to
medium. Given slightly different
character of the above resources, LR3 is sub-divided into following
sub-categories according to different combination of landscape components:
¡
LR3.1
Natural
¡
LR3.2
Natural
¡
LR3.3
Natural
¡
LR3.4
Natural Woodland on sloping area to the north of Sham Wan Towers – remnant natural slope during the development
of Ap Lei Chau Bridge, medium sensitive and
important LR locally to be respected. Dominant native
species include Macaranga tanarius, Mallotus
paniculatus, Sapium sebiferum and Schefflera
heptaphylla etc. with
combination of some self-seeded, Bauhinia variegata. Only 5% of them have
a DBH over 500mm due to their dense growing condition.
LR4 Mixed Woodland –
This resource includes patches of mixed woodland stands on remnant hill slopes
interspersed between the corridors of the main infrastructural and urban
development at Wong Chuk Hang and Ap Lei Chau. It forms green islands within an
urban landscape largely devoid of significant vegetation and serves to provide
sense of integration for the development within the area particularly where it
is established along existing road and infrastructure development. For a large
part this resource is isolated within the woodland on upland areas to the north
of the Study Area and so is locally significant in terms of its contribution to
the landscape context. Given that these resources are largely disturbed by
adjacent infrastructure development and despite being reasonability tolerant to
small changes the sensitivity of LR4 is considered to be medium to low.
Given slightly
different character of the above
resources,
LR4 is sub-divided into following sub-categories:
¡
LR4.1
Mixed
¡
LR4.2
Mixed Woodland in sloping
areas to the east of Wong Chuk Hang San Wai – remnant slope during the development of adjacent road and developments,
dominated by a combination of native and exotic species. It has a medium
sensitivity and is to be respected locally. Dominant
species include Acacia confusa, Aleurites
moluccana, Bauhinia variegata , Delonix regia etc. and some fruit trees.
¡
LR4.3
Mixed Woodland on sloping areas to the north of Hong Kong Police College – engineered slopes at the interface between
the Nullah and alongsides developments. It has a medium sensitivity and is to be respected locally. Dominant
species include Acacia confusa, Aleurites
moluccana, Bauhinia variegata ,
Casuarina equisetifolia, Delonix regia, Ficus hispida,
Macaranga tanarius, Pinus massoniana and Sterculia lanceolata etc.. Large
amount of bamboo are originally planted at the peripheries of School for screening
purposes. Only 2% of them have a DBH over 500mm.

DBH less than 500mm.
¡
LR4.7
Mixed Woodland on sloping areas to the north of Lee Nam Road – engineered lower slope of Yuk Kwai Shan. It has a low sensitivity and is an less important LR to be respected. Dominant species include Acacia confusa, Bauhinia variegata, Macaranga tanarius,
Khaya senegalensis, Melaleuca quinquenervia and Leucaena leucocephala etc.
All trees have a DBH less than 500mm.

LR5 Roadside Amenity – This resource are plantations along roadside and waterfront (nullah and harbour
areas) often established in planters or on engineered slopes along the major
infrastructure corridors usually serving
as buffer planting between developments and major road and infrastructure such
as the Aberdeen Tunnel Road, Heung Yip Road and Ap Lei Chau Bridge Road
etc. Those plantations make the greatest
contribution to the local landscape context in the form of a groups rather than
as individual specimen trees as they are largely formed by fast growing
non-native species, commonly found in roadside planting areas in Hong Kong and
have a high tolerance to the harsh urban and traffic environment. These tree
groups are often planted at close centres designed to create an instant effect
along transport corridors. This resource although important from a landscape
perspective has less value particularly ecological value than the mixed
secondary woodland on the hill slopes above. This resource is relatively
tolerant and is considered to have a medium to low sensitivity. Given slightly different character of the above resources, LR5 is sub-divided into following
sub-categories:
¡
LR5.1
Roadside
¡
LR5.2
Roadside Plantation alongsides of approaching roads to Aberdeen Tunnel – common roadside trees in raised planter with
exception of those located on a vacant land to the north and on sloping areas
to the south of Wong Chuk Hang Road Garden. Majority roadside species include Cinnamomum camphora, Bauhinia purpurea,
Livistona chinensis, Spathodea campanulata and Washingtonia robusta etc..
Majority of them have a DBH over 500mm. However, trees located on the vacant
land are relatively mature, and there are six trees have a DBH over 1000mm. In
addition, a Ailanthus fordii which is
protected species listed under the Forestry Regulations (Cap.96 sub. Leg.) are
found. Trees located on sloping areas located to the south of

Grassland / Shrubland Mosaic –
This is relatively common resource at higher elevations particularly near some
of the summits of the hill within the Study Area such as Yuk Kwai Shan and Nam
Long Shan and the lower slope of Bennet’s Hill and Tin Wan Shan adjacent to the
Wong Chuk Hang and Aberdeen urban areas. Although this landscape resource is
relatively resilient it still forms an important part of the overall landscape
character of the Study Area and provides a contribution to the overall context.
However in the context of this project the resource is considered to a have a
medium sensitivity. Common shrub species include Litsea rotundifolia, Ficus hispida, Dalbergia benthamii, Lantana camara
and Gordonia axillaris.

LR7.3
Chung Hom Kok – approaching
natural rocky shore along the southern edge of
LR8
Modified Watercourse – Whilst the Staunton Creek Nullah is
manmade concrete channel along
LR9
Marshland – A small seasonal
marshland area, located within the grounds of the ex-Canadian Hospital site, is
likely to have developed from a wasteland formally planned for hospital development,
but was abandoned due to the water
logging of the topography. Although not aesthetically attractive and with a
piecemeal distribution it helps in enhancing the sense of variety within the
landscape and contributes to the local context. Given its relatively small
size, distribution and unmanaged state it is likely to have a relatively low
sensitivity. Common plant species include Leucaena
leucocephala, Mikania micrantha, Ranunculus sceleratus and Commelina diffusa etc. They are loosely
disturbed at the periphery of this LR. All of them have a DBH less than 500mm.
LR10
Wasteland and Open Field –The
ex-Canadian Hospital Site was originally a construction site and was abandoned for years, the area is characterized its extensive
disturbance.. As described above a
small part of the site forms a marsh like landscape resource and the remainder
is covered by a combination of coarse grass, and shrub and small tree growth
which has colonised the site from the adjacent vegetated slopes. An open
field area is located to the east of the Ap Lei Chau waterfront adjacent to
warehouses and vessel repair areas associated with the Aberdeen Typhoon
Shelter. This area is currently used for the storage of dragon boats with an
intermittent coverage of vegetation. Given that these areas are largely
disturbed and derelict landscapes they are considered to be reasonability
tolerant to change and so have a low sensitivity. Given slightly different character of the above resources, LR10 is
sub-divided into following sub-categories:
¡
LR10.1
Open yard at waterfront promenade under Ap Lei Chau Bridge – informal
waterfront promenade currently occupied by ship repairing yards. A few
Ficus variegata var. chlorocarpa, Macaranga tanarius and Leucaena leucocephala
are found at the edge of this LR, they are self-seeded trees extending from
adjacent sloping areas. All of them are relatively small in size.
¡
LR10.2 Open yard at ex-Chung Hom Kok Quarry – originally occupied by
quarry activities.
¡
LR10.3 Open yard at ex-Canadian Hospital Site – originally occupied by
construction activities. Only a few self-seeded Leucaena leucocephala are found in this LR.
LR11
Agricultural Field – A
fragmentary remnant of the agriculture fields in Wong Chuk Hang Sun Wai which once formed a more significant part of this
landscape is located near the village settlement adjacent to portal for the
Aberdeen Tunnel. Recorded plant species are common crops such as Raphanus sativus, Ipomoea batatas and Carica papaya. However given the disturbed and fragmentary
nature of this resource it is reasonability tolerant to further modification
and so has a low sensitivity.
LR12 Open
Space – These areas include a
combination of tree, shrub planting with many having lawn areas located within
parks and amenity areas within individual residential urban developments
enhancing the amenity of recreational and residential spaces and accommodate
both passive and active recreation uses. It contributes to the local recreation
and residential landscape context both in the form of groups and often through
the utilisation of individual specimens of ornamental species. This resource
makes up a large proportion of the urban landscape of
¡
LR12.1
¡
LR12.2
¡
LR12.3
¡
LR12.4 Wong
Chuk Hang Road Garden – Given
to its relatively small size and largely served as sitting area for adjacent
neighbourhood, have mature planting area but only a few or without recreational
facilities, it has a medium sensitivity and is to be respected locally. The central core of the Garden is mainly covered by
shrub planting. Existing trees are located at the periphery of the Garden, they are ornamental species including Bauhinia ssp., Cleistocalyx operculatus, Callistemon viminalis, Koelreuteria bipinnata,
Lophostemon confertus and Peltophorum pterocarpum etc. An OVT, Ficus elastica,
is located within the Garden. Majority trees have a DBH less than 500mm.

LR12.7 Sitting Out Area adjacent to Staunton Creek
Nullah – it is a local sitting out areas for industrial
neighbourhoods, tree planting provides shade for
the users. Majority tree
species are Acacia confusa,
Bauhinia blakeana and Cassia
surattensis, majority of them
have a DBH less than 500mm. It has a medium

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 Study 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 Study Area. Magnitude of change
of these LRs and landscape Impact are assessed under Section 6.7.5.

Figures
6.3.1 to 6.3.6 shows the location of the LCAs listed below,
which form the Study Area, and Figures
6.4.1 to 6.4.5 provide a photographic record of the LCAs. The
identified LCAs are described below. Magnitude of change of these LCAs and
landscape Impact are assessed under Section
6.7.6.
¡
LCA1 Admiralty Commercial Landscape – The area is characterised by commercial
landscape composed of the high-rise lining
¡
LCA 2
¡
LCA 3 Mid-Level Upland Landscape – This area is characterised by scattered
residential developments within the Mid-levels of Hong Kong Island amongst the
vegetated hill slopes of
¡
LCA 4 Aberdeen Country Park Landscape – The Park is surrounded by Mount Gough to the
north, Mount Cameron to the east and Tin Wan Shan and Bennet’s Hill to the
south. The area is characterised by modified watercourses, upper and lower
Aberdeen Reservoirs which cut through the hill slopes. The central portion is
surrounded by mixed woodland at lower elevations with a greater proportion of
native woodland at higher elevations on the surrounding mountains. The park
contains recreational facilities for the enjoyment of visitors. Given its local
significance with the island south landscape context and its contribution to
the green back drop in the views looking from Aberdeen Channel, the sensitivity
of this LCA is high.
¡
LCA 5 Shouson Hill Low-rise Residential
Landscape –
This area is characterised by low-rise or house developments set within an
existing, undulating and elevated topography to the south of
¡
LCA 6 Wong Chuk Hang Industrial and
Institutional Landscape – This area is located to the west of Aberdeen Tunnel, a major entrance
gateway to the Island South area. The northeast portion of the area adjacent to
Aberdeen Tunnel is characterised by institutional developments including
schools and hospitals with remnant village settlements to the north of existing
tunnel portal. The western portion of the area is dominated by medium-rise
industrial buildings alongside
¡
LCA 7
¡
LCA 8
¡
LCA 9 Ap Lei Chau Island Landscape – An island located to the south of Aberdeen
Channel this area is characterised by two vegetated knolls to the south of the
island. The northwest portion of the island is largely urbanised composed of
high to medium-rise residential buildings alongside the waterfront, near the
¡
LCA 10 Chung Hom Kok Utilities Landscape-This area is located to the south of Chung Hom
Lok Shan at a abandon quarry adjacent to telecom facilities along the access
road. The site is very remote and
isolated. It is characterised by disturbed landscape with mixed woodland tree
along the access road at lower elevation, the higher elevation of the slope is
dominated by boulders and scrubland with scattered small trees. Given the
landscape context is highly disturbed by previous quarry activities with
relatively limited green features within the site the sensitivity of this LCA
is Low.
¡
LCA 11
¡
LCA 12 Wah Kwai Utilities Landscape- This area is located at the waterfront to the
south of Wah Kwai Estate. This is an
informal waterfront promenade originally form with the development of Wah Kwai
Estate. The site is characterised by a linear lawn with row of slope trees at
the northern edge along the road and the southern edge is bounded by concrete
parapet. Given the landscape context falls within highly developed area the
sensitivity of this LCA is Low.
Table 6.5 provides an assessment of the sensitivity of
each of the identified LCAs.

Given that the majority
of the proposed construction works along the railway alignment will utilise the
drill and blast tunnelling method, in particular the section between the
proposed ADM Station and the Nam Fung Portal, the Visual Envelope (VE) for
remaining works is limited locally to areas adjacent to the proposed
underground stations such as the ADM, LET and SOH Stations, and above ground
structures including the vent buildings, viaduct sections, bridge structures.
To the north of the
Study Area the VE is confined to the urban area surrounding the proposed ADM
Station at
Within the southern
portion of the Study Area the VE is more extensive due to the existing
topography and the nature of the adjacent built development surrounding the
proposed works. The VE is located in the areas adjacent to the proposed above
ground structures including station entrances, vent shafts, or plant buildings
etc., areas adjacent to proposed viaduct section with elevated stations, OCP
and WCH Stations, and from the proposed Nam Fung
Portal to Ap Lei Chau Bridge which aligns with the existing major road and
nullah corridors. The alignment is bounded by medium and high-rise developments
and extends from areas which have a view of the existing Ap Lei Chau Bridge
which aligns with proposed

Existing Visually
Detracting Elements
A number of the
existing elements within the landscape of the Study Area may be considered as
visually detracting in that they are visually incompatible with the existing
landscape and visual context. These elements and their role within the visible
landscape include:
¡
Aberdeen
Tunnel and approaching elevated roads;
¡
Staunton
Creek Nullah;
¡
¡
Existing
degraded industrial buildings at Wong Chuk Hang.
Existing Visual
Amenity and Visual Sensitive Receivers
Visually Sensitive
Receivers (VSRs) identified within the ZVI are grouped by residents who have
views of the proposed aboveground structures, and recreational users in parks, sitting-out
areas and waterfront promenade, staff and visitors in commercial, industrial
and institutional buildings, pedestrians
on footpaths
or waterfront areas and vehicular
travellers on the roads and marine locations who will be subject to similar views. Table 6.6 describes the sensitivity of the
selected VSRs within the ZVI, the quality of their existing views and
their ability to accommodate change. Table 6.7 identifies the magnitude of change and the potential impacts on
their visual amenity and the residual impact with recommended landscape
mitigation measures fully established. The potential visual impacts are mapped
in Figures 6.8.1 to 6.8.4.
The visual amenity
available to the identified VSRs within the ZVIs is largely characterised by
the views contained within road and
channel corridors and are largely limited low to medium-level views. The
open views along the corridors are generally shaped by the local topography, infrastructure, build environment and
vegetation. The visual quality within these ZVIs ranges from low to high and includes the
more degraded and restricted views available along the channel corridor at Wong
Chuk Hang where the context is dominated by unsightly industrial buildings to
the more scenic views across the Aberdeen Channel available from the
surrounding uplands and from the Aberdeen waterfront looking towards North Ap
Lei Chau, Aberdeen and Sham Wan. Alternative
views are only available to VSRs at
waterfront area and the more open views from VSRs
at elevated levels.
The sensitivity of the identified VSRs to further change ranges from high to low due with the value and quality of existing
views
being restricted by intervening
local topography, built environment and vegetation along road
corridors and within the main urban areas or more open and expansive views from
upland and elevated locations and from the waterfront. The VSRs are represented
by both transient or permanent receivers and their populations range from large
to small.
VSRs identified within
the ZVI are listed below and their existing visual context illustrated in Figures 6.6.1 and 6.6.5. Magnitude of change
of these VSRs and visual Impact are assessed under Section 6.7.7.
¡
VSR R1 Residents of Wah Kwai Estate – These VSRs are living at elevated levels and
have an open panoramic maritime views and developments alongside the Aberdeen
Channel. Given their wide open, visual context and permanent nature, their

elevated levels with the Chinese Permanent Cemetery in the foreground to the
east and industrial areas to the south. Although views are permanent in their
nature their visual context is largely characterised by disturbed landscapes in
the foreground and so their sensitivity to change is medium. These VSRs will
have a distant view looking towards the proposed

Rehabilitation Complex and St. Mary Home for the Aged within close proximity of
the proposed Ap Lei Chau Bridge landing area and Staunton Creek Nullah. Their visual context is largely interrupted
by elevated infrastructure elements and adjacent industrial buildings. Given
their degraded visual quality and permanent nature of the available views their
sensitivity to change is medium. These VSRs will have views of the proposed
viaduct and landing area of

VSR R9 Residents of developments on Shouson
Hill – These VSRs are located
within the low-rise or house type developments at the northwest periphery of
Shouson Hill. Low-level views are largely contained in their courtyard gardens
while more elevated views from upper floors have framed and partial views
towards the wider context. Views towards the north are characterised by the
buffer planting associated with the Aberdeen Tunnel Portal with glimpsed views
of the portal and box structures leading to OCP Station. Given the limited
extent of views with the developments and the quality of the landscape to the
north is interrupted by infrastructure at the area approaching to Aberdeen
Tunnel, their sensitivity to change is high. These VSRs will have partial views
towards
the proposed Nam Fung Portal and
box structure leading to OCP Station.

6.7 Identification and Evaluation of Environmental Impact
6.7.1 Impact on Existing Trees
A preliminary tree
survey in accordance with ETWB TCW No. 3/2006, ‘Tree Preservation’ has been
undertaken by the DDCs which forms part of the assessment of the existing
condition and potential impacts to the landscape resources of the Study Area.
This tree survey contained in Appendices
6.1 and 6.2 involves the identification of individual
trees within or adjacent to the works area, including a minimum 5m offset from either side of the proposed
railway alignment and site boundary of the associated station entrances, tunnel
portals, vent shafts, plant building and temporary works areas. Although there
are other existing trees within the 100m LVIA study boundary, they are not in
conflict with the proposed works, and hence the tree survey has been limited to
the works area and not the whole LIA Study Area.
The survey includes the
identification of individual trees, their species, size, health condition,
form, and amenity value.
The assessment found
approximately 5,768 trees within or located very close to the proposed works
areas of the Project, including approximately
2,570 trees located within public open spaces, roadside amenity areas and on
pavement, 1,966 slope trees,
1,125 Leucaena leucocephala
(銀合歡), undesirable weedy species, and 107 dead trees are found in the survey. Given the
ex-Canadian Hospital site and ex-Wong Chuk Hang Estate have been abandoned for
quite some time, Leucaena leucocephala
which is fast growing species naturally colonised the area and become dominant
in these two sites. As previously mentioned the majority of the existing trees
are located at the roadside along the existing infrastructure corridors whilst
the rest of tnem are located on the remnant natural or engineered slopes
adjacent to Staunton Creek Nullah;
and within the existing parks, gardens and sitting out areas. The existing tree
species are largely non-native. The main concentrations of native species
include the roadside areas and remnant slopes at Wong Chuk Hang and Ap Lei
Chau, and within the ex-Canadian Hospital Site.
These areas contain a combination of planted trees and specimens which have
naturally colonised the site.
¡
All five
OVTs found in the survey will remain unaffected or preserved and protected on
site. Seven numbers of protected trees will be preserved either in their current locations
or through transplantation.
¡
Four
numbers of tree had a DBH over 1M will be in conflict with proposed
works. One Ficus elastica located
in ex-Wong Chuk Hang Estate will be in conflict with the construction for WCH
Depot. Having
considered its extensive
aerial root system, it is not a good candidate for
transplantation. Its aggressive root and invasive growing characteristic
might affect the built structures and underground utilities. Pruning of
majority of these supporting roots might also be required during
transplantation that would seriously affect the balance and form of the trees.
Given the above horticultural and railway operation considerations, this
tree is considered to be felled instead of retention. Another three slope
trees located at ex-Canadian Hospital site and to the north of
¡
57% of trees having a DBH
ranged from 500 to 1000mm will be preserved in their current locations or
through transplantation. As
discussed in Section 6.6.1.3, few examples of Registered Old and Valuable Trees
(OVTs), rare and/or protected trees and
trees with a DBH over 1M are considered as important landscape resources that
would be preserved as far as technically feasible or through transplantation
and their final treatment will be subject to the tree felling application.
¡
A
breakdown of tree impacts on individual LRs are listed in Table 6.8
and summarised in the following sections.
The proposed scheme has
been designed to avoid impacts to existing trees as far as possible and so
minimise impacts on the landscape character and amenity of the Study Area.
Based on the findings of the preliminary tree survey it is estimated that
approximately 1,178 (20%) trees can be retained in their current locations.
6.7.3 Tree Transplantation Proposals
It is inevitable that
despite the objective of preserving trees wherever possible that some trees
will be in conflict with the proposed works. These trees are first considered
for preservation through transplantation to a recipient site where they can
still contribute to the landscape and visual amenity of the local area. In
terms of assessing the feasibility for transplanting the existing trees a
number of factors have been considered including their form, health and amenity
value. Also considered was the existence of rare and/or protected and/or
native species, the accessibility for machinery required for transplantation;
age; and the availability and the technical feasibility of providing recipient
sites. Based on the preliminary tree survey and with consideration for the
factors described above it is recommended that approximately 437 (8%) of the
existing trees are suitable for transplantation.
The proposed
transplantation of these trees will be required before the commencement of the
proposed works. The trees identified for transplantation include those of fair
to good form and health condition having contribution to the local landscape
context, relatively younger and accessible to machinery. Tree species, such as Bombax ceiba and Roystonea regia also have a higher predicted survival rate after
transplantation than less robust species. Wherever possible native species such
as Ficus spp. which have a relatively
high ecological and landscape value and are resilient to disturbance are also
recommended for transplantation. Transplanting these trees directly to a
permanent recipient site is preferred from a horticultural perspective.
Possible off-site planting areas include Medium Term Site under "Southern
District Greening Master Plan” at Wong Chuk Hang Area,
Given the scale of the proposed works, the need for the temporary works
areas and the operational requirement for railway, it is inevitable to have
some impact on existing trees.
These trees in conflict with the proposals are first considered for
transplantation. Where this is not possible the trees will be recommended for
felling and as such it would not be feasible to retain or transplant approximately
1,293
(22%) of existing trees within open space or in roadside amenity area and
1,628 slope trees (29%) However for a large part these trees are
non-native roadside or amenity trees, such as Acacia confusa, Bauhinia blakeana, Bauhinia purpurea, Cassia siamea,
Callistemon viminalis, Plumeria rubra etc. having lower individual
ecological and amenity value. According to ETWB TCW No. 3/2006, Tree
Preservation, all dead tree and undesirable species, Leucaena leucocephala, approximately 21%
of total number of trees, are proposed to be removed following good
horticultural practices to avoid spreading of undesirable tree species and to
ensure the public safety at where adjacent to dead trees.
6.7.5 Compensatory Planting Principles
Compensatory planting
forms major part of landscape mitigation measures. The planting principles will concentrate on planting new trees in the proposed amenity areas along the alignment and
surrounding the stations, and providing infill planting between the retained
and transplanted trees; and on the disturbed slope areas. According to ETWB TCW
No. 3/2006, Tree Preservation, compensatory planting requirement is not
applicable for felling of dead trees and self-seeded trees of undesirable
species, Leucaena leucocephala.
Given the above principles,
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 and planting areas adjacent to proposed stations
and above ground structures and within reinstated public open spaces will
utilise a combination of semi-mature to standard sized stock as shown in Figures
6.9.1.1 to 6.9.27 to create an
instant greening effect at local level. New planting areas along the alignment
will accommodate approximately
2,000 new trees. Planting of more board-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.
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
alignment of approximately 1.3 ha, would accommodate approximately 7,360 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 in accordance with ETWB TCW No. 3/2006. This tree replanting
ratio would compensate the total girth and number of tree loss within open
space or in roadside amenity area, 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 urban 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 provide the thermal comfort of
pedestrians. In the wider landscape context, the green backdrop will be
reinstated upon full establishment of replanting proposals on sloping areas.
Proposed planting on slope will utilise woodland mix with majority of native species. The species
selection for the areas along the railway alignment and adjacent to proposed
stations within the main urban areas will utilise a range of ornamental and
amenity tree species. These proposals will be subject to further development
during the detailed design stage of the project.
As mentioned above the
findings and recommendations of the preliminary tree survey report are subject
to the completion of a detailed tree survey and assessment and the preparation
of a felling application in accordance with ETWB TCW No. 3/2006. This will be
conducted during the detailed design stage of the project by DCCs 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 namely LandD, HyD,
LCSD and AFCD.
6.7.6 Impact on Existing Landscape Resources
Given the utilisation
of the drill and blast tunnelling method for the tunnel section between
Admiralty and Nam Fung Portal the natural woodland on upper Mid-levels area and
the surrounding Aberdeen Country Park will be preserved and the landscape
context of these areas largely unchanged. In addition the same tunnelling
method will also be utilised for the section of the alignment between the
proposed SOH and LET Stations, and so the plantation on Yuk Kai Shan will also
largely be preserved in-situ. With the exception of the above, the following
are the potential sources of impact to landscape resources:
¡
Some
existing carriageway and roadside spaces along proposed alignment will be in
conflict with cut and cover tunnelling works and the station and viaduct construction
works.
¡
The
existing Wong Chuk Hang Estate will be redeveloped to accommodate the proposed
WCH Station and railway depot.
¡
Part of
roadside spaces within the Lei Tung Estate will be affected by works for
proposed LET Station entrance and exit and the associated ventilation
structures.
¡
The
periphery of South Horizons will be affected by proposed SOH Station works.
¡
Some mixed
and secondary woodland on remnant slopes at the embankment of the Ap Lei Chau
Bridge and along Staunton Creek Nullah will
be affected by works for the proposed
¡
The
construction of the proposed tunnel box and Nam Fung portal / vent building at
the ex-Canadian Hospital Site may encroach slightly
on the fragment/degraded marsh type
landscape within the site.
¡
Some of
the existing amenity tree planting within Harcourt Garden, at the entrance of
Hong Kong Park; within the playgrounds and amenity areas at the Wong Chuk Hang
and Lei Tung Estates; and along the Lee Nam Road and the amenity area at Heung
Yip Road will be affected by the works.
¡
The
Aberdeen Channel adjacent to the existing crossing at the Ap Lei Chau Bridge
will be slightly affected by the column works for new
¡
Some existing
trees at
Table 6.8 describes
the source of impacts as a result of the railway proposals and presents the
magnitude of change on individual LRs. Magnitude of change on individual LRs are
listed as follows:
Large
According to the
assessment result in Table
6.8, having considered the determinants listed under Section 6.3.1.3, the magnitude of
change on some LRs would be large. It is due to either extent of impacts on
landscapae resources and the scale of proposed works within individual LRs are
relatively larger as a result of proposed works such as LR2.5 Carparking and Bus Deport adjacent to
Ocean Park, LR2.8 Demolition Site of
Ex-Wong Chuk Hang Estate and LR12.1 Harcourt Garden, and/or LRs have a
relatively lower compatability to proposed works including LR3.3 Natural
Woodland on sloping area to the north of Holy Sprit Seminary, LR3.4 Natural
Woodland on sloping area to the north of Sham Wan Towers and LR4.4 Mixed
Woodland on sloping areas alongside of Staunton Creek Nullah.
Intermediate
According to the assessment result in Table 6.8, the magnitude of change on some
LRs would be intermediate. It is due to either the extent of affected area
within the LRs, and/or the scale of proposed works and its compatability to
indivudal LRs, and duration of impact. These LRs include LR1.4 Aberdeen Tunnel approaching roads, LR1.5 Ocean Park Road, LR1.6 Major roads at
Wong Chuk Hang, LR1.9 South Horizon
approaching roads, LR1.10 Lee Nam Road, LR4.1 Mixed Woodland on sloping areas
along sides of Nam Fung Road, LR4.5 Mixed Woodland on sloping areas along Ap
Lei Chau Bridge Road, LR4.6 Mixed Woodland on sloping areas at the junction of
Ap Lei Chau Bridge Road and Lee Nam Road, LR5.2 Roadside Plantation alongsides
of approaching roads to Aberdeen Tunnel,
LR5.3 Roadside Plantation at the periphery of
carparking area to the north of Ocean Park, LR8 Staunton Creek Nullah, LR 9 Marshland, LR10.2 Open yard at ex-Chung
Hom Kok Quarry, LR12.4 Wong Chuk Hang Road Garden, LR12.9 Ap Lei Chau Park and
Waterfront Promenade and LR12.10 Football Pitch at Ap Lei Chau Bridge Road West
.
Small
According to the assessment result in Table 6.8, the magnitude
of change some LRs would be small as a result of proposed works. It is due to
the relatively smaller extent of affected area, and/or relatively higher
compatability of proposed works and its smaller scale within individual LRs,
and/or the relatively higher reversibility of LRs. These LRs include LR1.1 Major Roads at Admiralty, LR1.2 Supreme Court Road,
LR1.3 Nam Fung Road, LR1.7 Ap Lei Chau Bridge approaching roads,
LR1.8 Lei Tung Estate approaching roads,
LR1.11 Cyber Port approaching roads, LR1.12 Chung Hom Kok Road, LR2.7 Institutional Developments at Wong Chuk
Hang, LR2.12 Public Housing Developments at Lei Tung, LR2.13 Industrial and
Utilities Developments at Lee Nam Road, LR2.14 Residential Developments at Ap
Lei Chau West, LR2.16 Utilities Facilities and Industrial Developments at Tin
Wan waterfront, LR2.17 Mixed Use High Technology Developments at Pok Fu Lam,
LR3.1 Natural Woodland at the Peak and Mid-level Sloping Areas, LR3.2 Natural
Woodland on sloping area to the south of Wong Chuk Hang Estate, LR4.3 Mixed
Woodland on sloping areas to the north of Hong Kong Police College, LR4.7 Mixed
Woodland on sloping areas to the north of Lee Nam Road South, LR4.9 Mixed
Woodland on sloping areas to surrounding Chung Hom Kok Quarry, LR5.1 Roadside

LR10.1 Open yard at waterfront promenade under Ap Lei Chau Bridge and LR10.3
Wasteland at ex-Canadian Hospital Site and LR12.2 Hong Kong Park.
Nil
According to the assessment result in Table 6.8, there
would be nil change on the LRs including LR2.1 Commercial and Institutional Developments at
Admiralty, LR2.2 Civil Developments at Supreme Court Road,
LR2.3 Institutional Developments at Nam
Fung Road, LR2.4 Village and Residential
Developments at Lower Slope of Shouson Hill, LR2.6 Industrial Developments at Wong Chuk Hang,
LR2.9 Residential Developments at
Aberdeen Waterfront, LR2.10 Residential Developments at Ap Lei Chau Waterfront,
LR2.11 Mixed-use Developments at Ap Lei Chau Main Street, LR2.15 Residential
Developments at Pok Fu Lam, LR2.18 Utilities Facilities at Chung Hom Kok,
LR2.19 Ocean Park, LR4.2 Mixed Woodland on sloping area to the east of Wong
Chuk Hang Sun Wai, LR4.8 Mixed Woodland on sloping areas to the south of Police
School Road, LR7.3 Chung Hom Kok, LR 11 Agricultural Field, LR12.3 Queensway
Garden, LR12.5 Aberdeen Sports Ground, LR12.6 Sitting Out Area at Heung Yip
Road, LR12.7 Sitting Out Area adjacent to Staunton Creek Nullah and LR12.8
Aberdeen Tennis and Squash Centre.
Table 6.9 presents
the predicted unmitigated and mitigated (Day 1 and Yr 10/residual) impacts on the existing landscape
resources resulting from the proposed works during the construction and
operational phases of the project. These impacts also are mapped on Figures
6.5.1 to 6.5.13. The mitigated
(residual) impacts are assessed during the design year for the purpose of this
study and 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 of unmitigated impact are summarised
as follows:
Significant Impact
Given some of LRs,
which have a relatively higher sensitivity including woodland or mature plantation or open spaces, and the magnitude of change as a result of
proposed works on these LRs is relatively larger, these LRs would therefore experience a significant impact.
These LRs include LR3.3 Natural Woodland on sloping area to the north of Holy
Sprit Seminary, LR3.4 Natural Woodland on sloping area to the north of
This loss of these LRs will be mitigated through reinstatement of planting areas in
Moderate Impact
Given some of LRs,
which have a low to medium sensitivity including roads or developed areas,
mixed woodland, roadside amenity, grassland, wasteland and yards, waterbody, marshland or open spaces, and the magnitude of change as a
result of proposed works on these LRs is large to intermediate, these LRs therefore would experience a moderate impact. Besides, some LRs, which have a relatively
high sensitivity such as natural woodland, and the magnitude of change as a
result of proposed works on these LRs is relatively small, these LRs would also experience a moderate impact. These LRs
include LR1.2 Supreme Court Road,
LR1.3 Nam Fung Road, LR1.4 Aberdeen Tunnel approaching roads,
LR1.5 Ocean Park Road, LR1.6
Heung Yip Road, LR1.9 South
Horizon approaching roads, LR1.10 Lee Nam Road, LR1.12 Chung Hom Kok Road,
LR2.5 Carparking and Bus Deport

Lam, LR3.1 Natural Woodland at the Peak and Mid-level Sloping Areas, LR3.2
Natural Woodland on sloping area to the south of Wong Chuk Hang Estate, LR4.1
Mixed Woodland on sloping areas along sides of Nam Fung Road, LR4.3 Mixed
Woodland on sloping areas to the north of Hong Kong Police College, LR4.5 Mixed
Woodland on sloping areas to the north of Ap Lei Chau Bridge Road, LR4.6 Mixed
Woodland on sloping areas at the junction of Ap Lei Chau Bridge Road and Lee
Nam Road, LR5.1 Roadside Plantation at Admiralty, LR5.2 Roadside Plantation alongsides
of approaching roads to Aberdeen Tunnel, LR5.3 Roadside Plantation at the
periphery of carparking area to the north of Ocean Park, LR5.4 Roadside Amenity
at Lee Wing Street, LR 6 Grassland / Shrubland Mosaic, LR7.1 Aberdeen Channel,
LR 9 Marshland, LR10.2 Open yard at ex-Chung Hom Kok Quarry, LR12.2 Hong Kong
Park, LR12.4 Wong Chuk Hang Road Garden, LR12.9 Ap Lei Chau Park and Waterfront
Promenade and LR12.10 Football Pitch at Ap Lei Chau Bridge Road West
The loss of LRs will be
mitigated through the reinstatement of sloping and garden areas with both
native and amenity species integrated with preserved trees, responsive slope stabilising method to reduce
the impact on slope trees, reinstatement of roadside planting areas and
waterfront area. Greening measures on depot
façade in combination of new street tree planting on the footpath surrounding
the depot, in-filled between the preserved street trees at where space allows
will be implemented to alleviate the impact.
Slight
Given some of LRs,
which have a low sensitivity including roads or developed areas, mixed
woodland, roadside amenity, waterbody, or wasteland and open yards, and the magnitude of change as a result of
proposed works on these LRs is small, these LRs are therefore experienced a
slight impact. These LRs include LR1.1 Major Roads at Admiralty, LR1.7 Ap Lei Chau Bridge approaching roads,
LR1.8 Lei Tung Estate approaching roads,
LR1.11 Cyber Port approaching roads, LR2.13 Industrial and Utilities
Developments at Lee Nam Road, LR2.16 Utilities Facilities and Industrial
Developments at Tin Wan waterfront, LR4.7 Mixed Woodland on sloping areas to
the north of Lee Nam Road South, LR4.9 Mixed Woodland on sloping areas to
surrounding Chung Hom Kok Quarry, LR7.2 Telegraph Bay, LR8 Staunton Creek
Nullah, LR10.1 Open yard at waterfront promenade under Ap Lei Chau Bridge and LR10.3 Wasteland at ex-Canadian Hospital Site.
This impact will be
alleviated through the reinstatement of affected planting areas, with temporary
planting proposals such as climbing plants and bamboo planting adjacent to
proposed built structures at where pending for future GIC or property
developments at ex-Canadian hospital site, OCP Station and WCH Depot.
Negligible
As a result of proposed works that would not encroached to the LRs,
these LRs would not experience any perceptible
change including LR2.1 Commercial and Institutional Developments at
Admiralty, LR2.2 Civil Developments at
Supreme Court Road, LR2.3 Institutional
Developments at Nam Fung Road, LR2.4
Village and Residential Developments at Lower Slope of Shouson Hill,
LR2.6 Industrial Developments at Wong
Chuk Hang, LR2.9 Residential
Developments at Aberdeen Waterfront, LR2.10 Residential Developments at Ap Lei
Chau Waterfront, LR2.11 Mixed-use Developments at Ap Lei Chau Main Street,
LR2.15 Residential Developments at Pok Fu Lam, LR2.18 Utilities Facilities at
Chung Hom Kok, LR2.19 Ocean Park , LR4.2 Mixed Woodland on sloping area to the
east of Wong Chuk Hang Sun Wai , LR4.8 Mixed Woodland on sloping areas to the
south of Police School Road , LR7.3 Chung Hom Kok, LR 11 Agricultural Field,
LR12.3 Admiralty Garden, LR12.5 Aberdeen Sports Ground, LR12.6 Sitting Out Area
at Heung Yip Road, LR12.7 Sitting Out Area adjacent to Staunton Creek Nullah,
LR12.8 Aberdeen Tennis and Squash Centre.
The assessment
contained in Table 6.9 concluded that even though
there is significant to moderate impact on some of LRs, the majority of the
works areas will be reinstated to its original status or with proposed new roadside and amenity
planting areas along the alignment and woodland mixed
planting on disturbed sloping areas.
In combination with tree preservation proposals, these will mitigate the loss and will retore and
enhance the landscape context. The
Conceptual Landscape Master Plans shown in Figures
6.9.1.1 to 6.9.27 illustrate landscape proposals along the railway alignment and adjacent to built
structure as that will alleviate the potential impact on the LRs. The
recommended landscape mitigation measures and residual impact on these LRs is
further discussed in Sections 6.8
and 6.9.

6.7.7 Impact on Existing Landscape Character
Due to the scale of the
proposed scheme there are likely to be some adverse impacts on the existing landscape
character although some sensitive areas will be spared impact due to the
proposed construction approach. Given
the proposed use of the drill and blast tunnelling method for the tunnel
section between Admiralty and proposed Nam Fung Portal and the section between the proposed SOH and LET
Stations majority landscape characters would subject to a
slight to moderate impact due to construction of viaduct, Aberdeen Channel
Bridge, above ground stations, vent shaft and plant buildings. Table 6.11 presents the predicted unmitigated and
mitigated (residual) impacts on the existing landscape character areas resulting from the proposed works during the
construction and operational phases of the Project.
These impacts also are mapped on Figure
6.3.1 to 6.3.6.
The mitigated (residual) impacts are assessed during the design year for the purpose
of this study and taken as being between 10 and 15 years after railway extension open to public when the proposed mitigation
planting is deemed to have reached a level of maturity, which is sufficient for
it to perform the design objectives. The
predicted mitigated (residual) impacts are further discussed in Section 6.9.
Table 6.10 describes
the source of impacts as a result of the railway proposals and presents the
magnitude of change on individual LCAs. Magnitude of change
on individual LCAs is listed as follows:
Intermediate
According
to the assessment criteria set up in Section
6.3.1.3 and the result in Table 6.10, certain extent of perceptible
change on landscape characters as a result of the loss of landscape resources
such as Harcourt Garden, wooded slopes along Staunton Creek Nullah, Aberdeen
Channel and ex-Quarry site at Chung Hom Kok, the magnitude of changed of some
LCAs is intermediate including LCA1 Admiralty Commercial Landscape, LCA 6 Wong Chuk Hang Industrial and
Institutional Landscape, LCA 7 Nam Long Shan Maritime and Recreational
Landscape and LCA 10 Chung Hom Kok Utilities Landscape (construction phase
only).
Small
According
to the assessment criteria set up in Section
6.3.1.3 and the result in Table 6.10, small extent of perceptible
change on landscape characters as a result of proposed works, the magnitude of
change on LCAs is therefore small. These
LCAs include LCA 2 Hong Kong Park Recreational Landscape, LCA 8
Aberdeen Waterfront Landscape, LCA 9
Ap Lei Chau Island Landscape, LCA
11 Telegraph Bay Institutional Landscape (construction phase only) and LCA
12 Wah Kwai Utilities Landscape.
Nil
No perceptible change
on LCA 4 Aberdeen Country Park Landscape, LCA 3 Mid-Level Upland Landscape and
LCA 5 Shouson Hill Low-rise Residential Landscape as a
result of proposed works, the landscape character remain unchanged, the
magnitude of change is therefore negligible.
¡
.
Besides, given proposed works in LCA 10 Chung
Hom Kok Utilities Landscape and LCA 11
Telegraph Bay Institutional
Landscape are temporary in nature, no works will be undertaken during
operation, there is no perceptible change during operation phase.
Table 6.11 presents the predicted unmitigated impacts and
are discussed in the following sections.
¡
LCA1 Admiralty Commercial Landscape - Given
¡
LCA 2
¡
LCA 3 Mid-Level Upland Landscape & LCA 4
¡
LCA 5
Shouson Hill Low-rise Residential Landscape – Shouson Hill is dominated by low-rise housing
development integrated with the vegetated sloping area along the access road to
the area. The northern periphery of the area is dominated by Aberdeen Tunnel
and its associated approaching road. No proposed works are proposed within the
area. Indirect impact on this LCA is due
to construction works of Nam Fung portal/ vent building and box structure in
ex-Canadian Hospital site located in distance on the other side of Aberdeen
Tunnel and the temporary loss of
¡
LCA 6
Wong Chuk Hang Industrial and Institutional Landscape - The
introduction of the Nam Fung portal / vent building, and viaduct connecting the
elevated OCP and WCH Stations would lead to
changes in the amenity areas approaching the Aberdeen Tunnel and Staunton Creek Nullah. Despite the proposed alignment and
stations being elevated within this character area it should be noted that
existing landscape has been largely degraded though infrastructure and
industrial development hence the proposed works would fit within this context.
In addition the proposed WCH
Station and railway depot following
the redevelopment of the Wong Chuk Hang Estate will lead to a comprehensive
change to the existing landscape character. Change on the industrial character is
therefore intermediate. Given the medium sensitivity of this LCA, this LCA would be subject to a moderate adverse
unmitigated
impact due to the construction
works and during the operational phase of the project.

LCA 7 Nam Long Shan Maritime and Recreational
Landscape – As a large part of
the above ground alignment would follow the Staunton Creek Nullah it is likely that it will be screened to
an extent by the existing institutional uses at the northern periphery when
looking from the south. Change on the local landscape character is intermediate. Despite
the change of amenity being limited to the northern periphery of the area,
considered its medium sensitivity, the unmitigated impacts on this LCA will be
moderate during the construction and operational phases of the project.
¡
LCA 8
Aberdeen Waterfront Landscape –
Owing to its proximity to proposed Aberdeen Channel although no construction
work is proposed directly within this area
it is likely that there will be some indirect impacts due to the construction
of the proposed Aberdeen Channel Bridge and the associated works areas along
the waterfront promenades of Aberdeen and Ap Lei Chau. Change on waterfront
character is small due to construction
works for the proposed bridge. Given the medium sensitivity of this LCA, the unmitigated impact on this LCA will be
moderate during the construction and operational phases of the project.
¡
LCA 9 Ap
¡
LCA 10 Chung Hom Kok Utilities Landscape – Existing Chung Hom Kok Shan is largely
characterised by boulders and grass at higher elevation whilst the lower
elevation is dominated by slope trees and shrubland alongside of the access road
to the quarry and telecom utilities at the toe of southern slope. The selection
of magazine site in the quarry which is a disturbed landscape would minimise
the impact to the amenity and fit into the landscape context. Given the extent
of affected area is sited at the ex-quarry that would minimise the impact on
existing landscape context, the magnitude of change is found intermediate.
Given its low sensitivity, this LCA will be subject to a slight adverse
unmitigated impact during the construction stage. Given the nature of proposed
works is temporary use only during construction phase, unmitigated impact on
this LCA is negligible during operation phase.
¡
LCA 11 Telegraph Bay Institutional Landscape – Similar to the careful site selection of
magazine site, selected location of barging point at Telegraph Bay waterfront
associated with existing sewage and construction facilities adjacent to Cyber
Port would fit into the landscape context , hence the magnitude of change to
landscape amenity is small. Given its low sensitivity, this LCA will be subject
to a slight adverse unmitigated impact. Given the nature of proposed works is
temporary use only during construction phase, unmitigated impact on this LCA is
negligible during operation phase.
¡
LCA 12 Wah Kwai Utilities Landscape – Similar to LCAs 10 and 11, selected location of
works area or potential site for the nursery of transplanted trees at
waterfront to the south of Wah Kwai Estate would fit in the local landscape
context. This waterfront area is dominated by linear lawn with trees to the
north along the access road, hence the magnitude of change is small. Given its
low sensitivity, this LCA is therefore subject to a slight adverse unmitigated
impact during the construction and operation of proposed works.

The potential visual
impacts (unmitigated) on identified VSRs resulting from the proposed works during
the construction and operational phases of the Project are summarised in the
following sections and listed in Table 6.12. These
impacts are also mapped on Figures
6.8.1 to 6.8.4. 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. The residual impacts (mitigated) are discussed
under Section 6.9.
Significant
Although some amenity
of VSRs will be spared impact due to the proposed tunnel construction, there
are likely to be some significant adverse impacts on the visual amenity of some
VSRs due to introduction of above ground structures including viaduct, above ground OCP and WCH Stations, WCH
Depot and Nam Fung portal/ vent building and Aberdeen Channel Bridge such as VSR R6 Residents of community facilities to the
east of Ap Lei Chau Bridge, VSR R7 Residents of estates in Wong Chuk Hang, VSR
C7 Users of sitting-out areas and playground at Heung Yip Road adjacent to the
nullah, VSR C8 Visitors to Tai Wong Ye Temple and VSR T3 Travellers along Heung Yip Road and Ocean Park Road. These VSRs will be subject to a large change of visual context and amenity with the temporary loss of roadside amenity
areas and vegetated sloping areas and proximity to the works. However, the majority of the works areas will
be reinstated with provision of new amenity area adjacent to station and
underneath the viaduct.
Moderate
Due to the proximity of Aberdeen Channel Bridge, viaduct, box structure at ex-Canadian Hospital site,
and partially or above ground stations (ADM, OCP
and WCH Stations), vent buildings at Hong Kong Park and Nam Fung Road and plant
building at Lee Wing Street, VSRs
such as VSR R1 Residents of Wah Kwai Estate,
VSR R2.1 Residents of Ap Lei Chau Estate, VSR R2.2 Residents of South
Horizons, VSR R3.1 Residents of estates in eastern Ap Lei Chau, VSR R3.2

in Wong Chuk Hang Industrial Buildings, VSR O4 Staff and Students in Police
College, VSR O6 Workers in Commercial Buildings along Queensway and Harcourt
Road, VSR O7 Staff and Students in Hong Kong Academy of Performing Arts PVSR
O8 Future Staff and Visitors in Central
Government Complex and LegCo Complex and associated open spaces at Tamar Site,
Central, VSR O9 Staff and Visitors in
Jumbo Floating Restaurant in Aberdeen South Typhoon Shelter , VSR O10 St. Paul’s Co-educational College Primary
School, VSR T1 Travellers along Aberdeen Channel, VSR T2 Travellers on the Ap
Lei Chau Bridge, VSR T4 Travellers on Wong Chuk Hang Road, VSR T5 Travellers on
Nam Fung Road, VSR T6 Travellers on Harcourt Road, VSR T7 Travellers on
Queensway Road and VSR T8 Travellers on
Supreme Court Road, will be subject to a small to intermediate change of visual context
with the temporary loss of park and roadside amenity areas and vegetated
sloping areas and proximity to the works. However, the majority of the works
areas will be reinstated or new urban park and amenity areas with greening
measures adjacent to built structures. Their visual amenity contained by
urbanised or infrastructures landscapes would subject to intermediate
change. Hence these permanent/ transient
VSRs will experience a moderate impact in the absence of mitigation measures
during construction and operation phase.
Slight
VSRs such as VSR R4
Residents of estates in western Aberdeen, VSR C1 Visitors of Permanent Chinese
Cemetery, Aberdeen, VSR C2 Hikers in Aberdeen Country Park, VSR O1 Staff and
Students of Hong Kong True Light College, VSR O5 Staff and Students in South
Island School and VSR O11 Workers and visitors in Cyber Port, will have views
in distance or partially obstructed/ oblique views to proposed Aberdeen Channel
Bridge or barging point at Po Fu Lam.
Given to the nature of views and viewing distance involved, proposed bridge
will not form a major component in the wider context of urbanised
Negligible
Given the viewing
distance (over 1000m) and nature of views, visual amenity of Residents of
developments on the VSR R10 Peak and Mount Kellet and VSR R11 Residents of
developments on Mount Cameron who have an overview of Aberdeen and Ap Lei Chau
will not have perceptible change as a result of proposed works which will
merged into the building areas, and hence these VSRs will experience a
negligible impact.

This section reviews
the projects currently in progress or planned within the Study Area, such as
the Central Government Complex and LegCo Complex at the Tamar Site and the
proposed Ocean Park extension and hotel development currently under
construction, and planned GIC or property development at ex-Canadian Hospital
Site, adjacent to OCP Station and above WCH Depot , which will result in
landscape and visual cumulative impacts
including the degradation of landscape character and visual amenity, and the
loss of landscape resources.
The
construction works for the proposed expansion of
Given the potential to develop the top of WCH
depot to the proposed property development tentatively a year or two upon the completion of
Depot construction and some of the roof space are reserved for
vent or louver for the depot ventilation, greening measures are not technically
feasible on the roof. The greening measures for the depot itself would be
focused on roadside and depot façade at where the operation of the depot would
not be interfered. The landscape and visual amenity will likely be further
enhanced through the landscaping measures undertaken in the proposed property
development stage.
Based on the latest programme available, the
following planned project will be completed during the construction phase or before
the operation of proposed railway, it is not envisaged that there will be
cumulative landscape and visual impacts from the concurrent implementation of
the following planned projects:
¡
Central
Reclamation Phase III;
¡
Wan Chai
Development Phase II and Central-Wan Chai Bypass; and
¡
Central
Government Complex and LegCo Complex at the Tamar Site.
The enabling works of SCL will be carried out
under SIL(E) at the time of ADM construction. Some SCL facilities have been
integrated with proposed works under SIL(E) to minimise cumulative impacts to
landscape and visual context.
Mitigation measures to address the potential 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 EIA.
6.1 Mitigation of Adverse Environmental Impact
The landscape
mitigation measures described in this report are at a level which both
demonstrates their ability to alleviate the potential landscape and 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. More
detailed landscape and compensatory planting proposals are developing by DDCs during detailed design of this project
following the completion of the detailed Tree Survey Report and will seek
approval from relevant departments at that stage.
The landscape and
visual 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 including for example the proposed
above ground structures, viaducts, stations and new bridge structures. The aim
of the mitigation measures is to:
¡
Alleviate
where possible those landscape and visual impacts which are unavoidable through
the review of alignment and locations of the proposed above ground structures
associated with the railway operation.
¡
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 and visual context of the surrounding areas.
¡
Provide a
co-ordinated approach between the ecological and landscape mitigation proposals
where there is an interface.
The Landscape Design Concept
Drawings of proposed station and alignment and associated railway structure and
the Conceptual Landscape Plans presented as Figure
6.9.1.1 to 6.9.31 demonstrate the
main landscape and visual mitigation strategies and the application of design
mitigation measures including integrated design approach, compensatory and new
roadside planting proposals and slope treatment. Application of the recommended
mitigation measures are mapped on the plans.
It is recommended that
the Environmental, Monitoring and Audit Requirements (EM&A) for landscape
and visual resources described in Section
6.10 of this report is undertaken during detailed design stage and both the construction and operational phases of
the Project.
6.1.2 Primary Mitigation Measures
In accordance with the
EIAO-TM, the hierarchy for landscape and visual impact mitigation is first
avoidance of impact, then minimisation of impact and finally compensation of
impact. As has been described in the
Project description in this report, the current proposals have been undertaken
to fulfil the following objectives:
¡
Minimisation
of potential impacts on landscape resources such as watercourses and existing
trees by review of the alignment and location of above ground structures.
¡
Restoration
and enhancement of existing landscapes through planting large feature and
ornamental trees following the completion of the construction phase of the
project, this will create an instant greening effect be apparent in the
enhancement of the streetscape.
¡
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
EIAO-TM, 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 lost landscape resources as far as is possible given the
Project constraints.
6.1.3 Secondary Mitigation Measures
A series of mitigation
measures designed to alleviate impact and where possible compensate for 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
and visual impact mitigation measures are summarised in Tables 6.13
and 6.14.
Table 6.13: Proposed
Construction Phase Mitigation Measures
|
Mitigation Code |
Mitigation Measure |
|
CP1 |
Preservation of Existing Vegetation - The proposed works should avoid disturbance to the existing trees and vegetation as far as practicable within the works areas. The tree preservation proposals should coordinate with the layout and design of the engineering and architectural works. It is recommended that a full tree survey and felling application be undertaken and submitted for approval by the relevant government departments in accordance with ETWB TCW No. 3/2006, ‘Tree Preservation’ during the detailed design phase of the project. Where possible all trees which are not in conflict with the proposals would be retained and shall be protected by means of fencing where appropriate to prevent potential 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 - The landscape of these works areas should be restored to their original condition or enhanced through the introduction of new amenity areas or open spaces following the completion of the construction phase. Construction site controls shall be enforced, where possible, to ensure that the landscape and visual impacts arising from the construction phase activities are minimized including the storage of materials, the location and appearance of site accommodation and the careful design of site lighting to prevent light spillage. Screen hoarding may not be practicable at some locations due to the close viewing distances involved, the length of the alignment and the spatial constraints of the works area. Where hoarding is practicable the design of the finishes will adopt a coherent approach with a decorative effect. |
|
CP3 |
Implementation
of Mitigation Planting and planting species selection
- Replanting of existing/disturbed
vegetation should be undertaken at the earliest possible stage of the
construction phase of the project and this should use predominantly native
and/or ornamental plant species.
Proposed mitigation planting shall not only limit to conventional
amenity planting, but also considered alternative greening measures such as
vertical greening for screening or soften the built structures. Small shrubs,
climbing plants, grass and groundcovers shall be used in specific locations
according to site condition and at where would not interfere the operation of
railway and its associated facilities. |
|
CP4 |
Transplantation of Existing Trees –
Approximately 437 existing
trees, from roadside amenity areas
or open spaces are recommended to be transplanted under the current
proposals. The final recipient sites should be, as far as space allows,
adjacent to their current locations alongside of the alignment to retain
their contribution to the local landscape context. However the majority of the transplanted
trees will be relocated directly
to off-site planting areas.
Possible off-site planting areas include Medium Term Site under
"Southern District Greening Master Plan” at Wong Chuk Hang Area, |

OP1 |
The design of the proposed engineering and building structures - will incorporate design features as part of design 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 schemes including the locations of the proposed above ground structures. Grouping of station facilities and structural components as far as technically feasible to reduce the mass of above ground structures. The disposition and height profile of the proposed above ground structures to respond to the existing context and minimise potential wall effects. Measures may include the creation of setbacks, articulating the development frontage, maintenance of view corridors and the utilisation of stepped 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 facilities further through the use of natural materials 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
potential glare effect. Incorporation
of landscaped terraced edges or other form of greening measures on built
structures where conditions allow particularly those fronting the public
realm to reduce the apparent visual mass of the structure and create a more
subtle transition with the pedestrian level streetscape. Innovative architectural design includes the adoption of recessive colours for the building, viaduct and noise barrier finishes and colour blocking to reduce the collective visual mass of the development. Responsive lighting design – Aesthetic design of architectural and track lighting with following glare design measures: · Directional and full cut off lighting is recommended particularly for recreation and roadside areas to minimize light spillage to the surrounding areas. · Minimize geographical spread of lighting, only applied for safety at the key access points and staircases; · Limited lighting intensity to meet the minimum safety and operational requirement; and · High-pressure sodium road lighting is recommended for more stringent light control reducing spillage and thus visual impacts. |
|
|
OP2 |
Roadside and Amenity Planting – The
planting proposals will utilise large ornamental trees to maximise the area
of visible greenery, soften the interface between the proposed scheme and
adjacent urban fabric and enhance the thermal comfort of adjacent spaces. The implementation of new planting shall
be undertaken as soon as technically feasible at sectional completion stage
during construction to ensure the effectiveness of this mitigation during
operational stage. Planting proposals will respond to the need for visual access in the views from the adjacent neighbourhoods to the roadside or rural landscape. Whereas dense foliage plants will be provided at other locations to screen and frame views, provide a more shaded environment for pedestrians and provide accents within the existing roadside planting. The planting on sloping ground and areas adjacent to existing woodland will utilise predominantly native species improving the ecological connectivity between existing woodland habitats and creating a more unified and coherent landscape framework. |
|
|
OP3 |
Compensatory Planting Proposals – Given that the works are largely located within urban areas, alongside existing roads and beside the Staunton Creek Nullah areas for new tree planting are limited. However the proposals have sought to utilise all available spaces for new tree and shrub planting to screen views of the proposals and where this is not possible soften their architectural form and enhance their visual integration within the future landscape context. 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 and planting areas adjacent to proposed stations and above ground structures and within reinstated public open spaces will utilise a combination of semi-mature to standard sized stock as shown in Figures 6.9.1.1 to 6.9.27 to create an instant greening effect at local level. New planting areas along the alignment will accommodate approximate 2,000 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. 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 alignment of approximately 1.3 ha, would accommodate approximately 7,360 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 within open space or in roadside amenity area, 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 urban 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. In the wider landscape context, the green backdrop will be reinstated upon full establishment of replanting proposals on sloping areas. Proposed planting on slope will utilise woodland mix with majority of native species. The species selection for the areas along the railway alignment and adjacent to proposed stations within the main urban areas will utilise a range of ornamental and amenity tree species. These proposals will be subject to further development during the detailed design stage of the project. As mentioned above the findings and recommendations of the preliminary tree survey report are subject to the completion of a detailed tree survey and assessment and the preparation of a felling application in accordance with ETWB TCW No. 3/2006, Tree Preservation and LAO PN 7/2007 Tree Preservation and Tree Removal Application for Building Development in Private Projects. This will be conducted during the detailed design stage of the project by DCCs 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 namely LandD, HyD, LCSD and AFCD. |

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. |

OP5 |
Noise Mitigation Structures - Under the current proposals the requirement for noise barriers would
be limited to the viaduct and bridge section of the scheme proposals along
the Staunton Creek nullah and across Aberdeen Channel. The proposed noise
attenuation structures will form a combination of noise barriers and
semi-enclosures. The design of these structures would be responsive to the
landscape through which the track would pass which is essentially an urban /
urban fringe/ semi-rural environment characterised by high-rise residential
property and commercial / warehouse premises; and the wooded hill slopes of
the landscape lining the course of the nullah. The barriers would also pick
up on existing design themes in the station complexes responding to the local
context such as greenback drop along the nullah and maritime character of
Aberdeen Channel to ensure that the new structure would be visually
compatible with structures to which it is connected. The
design criteria for the noise mitigation structures installed along the
trackside should not be limited to the functional requirements of mitigating
train noise. It should also seek to make a positive contribution to the urban
/ urban fringe / semi-rural landscape character of this area and by doing so
improve the perceived landscape quality of the area. These barriers would be
visible from some VSRs identified in the study. The design criteria should seek to: ·
Promote the innovative use of
materials for absorptive panel, such as Plexiglas, fibreglass, reinforced concrete etc, whilst
remaining aware of the design life span of each of the elements incorporated
in the design; ·
Reduce the visual effect of the
structure through the use of form, materials, textures colours and tones; ·
Incorporation of articulation
in the façade of the noise barriers / enclosures through the use of some
transparent sections near the upper portion of the proposed structure to
break up the horizontal emphasis of viaduct and bridges; ·
Reflect the chromatic context
of the surrounding urban landscape through the use of colour panels in the
proposed noise barrier, and create themes for various section responding to
local characters; and, ·
Utilise materials, which are
non-reflective avoiding glare from incident sunlight. |
|
|
OP6 |
The design of the proposed Engineering Structures such as viaduct should pay particular attention to the appearance and construction methods of the structures which form part
of these proposals, 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. The major engineering structures shall
seek approval from ACABAS on design principle and
approach for these engineering structures. This will then inform the design
and visual appearance of the proposed structures in the detailed design phase
of the project. Even though overall the designs would consider the following
principles: ·
The viaduct structures would aim to “touch”
the ground as lightly as possible in order to minimise disturbance to the
existing landscape and vegetation below the structures. This would be
achieved by designing slender, rounded viaduct columns spaced the maximum
distance apart. Where conditions allow, the viaducts would be constructed
using pre-cast methods and launched from columns rather than scaffolding. The
viaduct should be designed to achieve where appropriate a graceful, curving
alignment; ·
Landform and vegetation in
areas disturbed by construction works would be reinstated to blend with the
existing landscape patterns; ·
Wherever light levels, the
water regime and the requirements of the enviromental 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 innovative 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; and ·
Drainage structures would where
possible be concealed within the structure of the proposed viaducts. |

6.1.4 Programme for Landscape Works
The landscape works
will closely follow the completion of the construction of the proposed works. The design year for the purpose of this study
is taken as approximately 10 to 15 years after the scheme opening when the
proposed soft landscape mitigation is mature. The landscape works will be
implemented at the earliest possible time in the planting season immediately
following the sectional completion of the construction works. The
implementation schedule of landscape works is presented in Section 14 in this report
and also presented in the EM&A Manual.
6.2 Evaluation of Residual Impact
Overall, in terms of
residual landscape and visual impacts the main effects will primarily result
from the disturbance to a number of park
and open space landscapes, some woodland areas and the interruption of existing
roadside and waterfront landscapes. As the majority of works areas will be
reinstated to their original condition or enhanced to form new amenity areas,
it is evident that the predicted impacts will be alleviated upon full
establishment of landscape and visual mitigation measures.
For the most part the
landscape character of the Study Area will largely remain unchanged after the
full establishment of the recommended mitigation measures, as:
¡
Responsive
scale and building height profile integrated with local urban context will be
adopted.
¡
Integration
as far as technically feasible new built structures with existing.
¡
Provision
of planting areas along the alignment and adjacent to proposed stations.
¡
Reinstate
temporary works areas to new landscape sitting areas and/or recreation areas
for the use of neighbourhood community.
¡
Incorporation
of vertical greening and green roof on built structures as far as technically
feasible.
¡
Tree
preservation and new tree planting proposals, where space allows, will be
implemented alongside and underneath the viaduct and adjacent to proposed
stations.
The planting proposals
also form part of compensatory planting proposals for the loss of landscape
resources, such as existing trees, it will benefit the future landscape and
ecology context within the Study Area.
6.2.2 Residual Impact on Landscape Resources (Yr10)
Landscape and visual
mitigation measures recommended and mitigated (residual/Yr10) impact for individual LRs assessed in Table 6.9 and summarised as follows.
Slight
The significant impact on some LRs including wooded area and open space will be alleviated from significant to moderate (Day 1 construction and operation) to slight impact (Yr10). The is evident through full establishment of the mitigation measures
discussed in Section 6.8, including
the reinstatement of wooded sloping and open spaces with both native and amenity species integrated with preserved trees,
and other form of greening measures at where condition allows. The disturbed
open spaces and gardens will be reinstated or redesigned with a modern park
design approach. These LRs include LR3.3 Natural Woodland on sloping area to
the north of Holy Sprit Seminary, LR3.4 Natural Woodland on sloping area to the
north of
Negligible
The moderate to slight impact on the majority of remaining LRs including roads and highways, developed
areas, wooded sloping areas, roadside amenity, grassland/shrubland mosaic, waterbody, wasteland and football pitch
will be alleviated from moderate to slight adverse (Day 1 construction
and operation) to negligible (Yr10) with full establishment of landscape mitigation
measures including the re-instatement of disturbed areas as far as technically
feasible with plantation of woodland mix on sloping areas and ornamental
roadside planting.
Slight Beneficial
The creation of new open
spaces with tree and shrub planting and sitting out areas underneath proposed
viaduct will also beneficial to existing landscape context along Staunton Creek
Nullah (LR8). Open yard at waterfront
promenade under Ap Lei Chau Bridge (LR10.1)
originally utilised for dragon boat storage and vessel repair area will be
enhanced with full establishment of planting at the embankment of proposed
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
and planting areas adjacent to proposed stations and above ground structures
and within reinstated public open spaces will utilise a combination of
semi-mature to standard sized stock as shown in Figures
6.9.1.1 to 6.9.27 to create an
instant greening effect at local level.
Following the planting
concepts
discussed in Section 6.7.5, a replanting ratio of minimum 1:1 in terms of
quantity and quality would be achieved except for slope works according to ETWB TCW No. 3/2006. The retention of existing
trees through their preservation in-situ and transplanting and the successful
establishment of the newly planted trees will form part of the roadside and
slope planting enhancing the amenity of the local areas and providing for the
thermal comfort of pedestrians. In the wider landscape context, the green
backdrop will be reinstated upon full establishment of greening on sloping
areas. The proposed compensatory and new tree planting will utilise native
species to
6.2.4 Residual Impact on Landscape Character Areas
Landscape and visual
mitigation measures recommended and mitigated (residual) impact for individual
LCAs assessed in Table
6.11 and summarised as
follows.
Negligible impacts
The moderate impact on
overall Admiralty Commercial Landscape (LCA1) due to the temporary loss of
Harcourt Garden and roadside planting at Fenwick Pier Street and Supreme Court
Road will be alleviated to a slight level during the construction and operation
phases (Day
1) of the project through the
preservation of existing LRs including trees and the impact will be further
reduced to a negligible level during operation phase (Year 10) of the Project with full establishment of
landscape and visual mitigation measures. These measures include reinstatement
of
The landscape character
of Harcourt Garden will be changed from single level garden area currently lack
of variation of recreation facilities and largely used for pedestrian
circulation purpose to a terraced modern urban park character accommodated
shaded seating area and other recreation facilities. The form of new
The moderate impact on
the character of Hong Kong Park Recreational Landscape (LCA 2) in particular
the entrance area adjacent to proposed vent shaft will be alleviated to a
negligible level during operation phase (Year 10) of the Project through the preservation of existing trees, full
establishment of new roadside planting integrated with existing OVTs and
vertical greening on built structures. The affected area will be reinstated although largely
its frontage would be hard paved for maintenance access and manoeuvring of
refuse collection truck to re-instated RCP adjacent to the building and
reserved for the works area for SCL.
Besides, the road modification works is carefully designed to avoid impact on
existing OVTs in roadside planters.
The character of Wong
Chuk Hang Industrial and Institutional Landscape (LCA 6), Aberdeen Waterfront
Landscape (LCA 8) and Ap Lei Chau Island Landscape (LCA 9) will be subject to
relatively extensive construction phase works and their attendant disturbance
to the setting and landscape amenity of these areas resulting in a moderate
level of impact. However with the implementation of the proposed mitigation measures these
impacts will be alleviated to a slight level of impact during the construction
and operation phases (Day 1) of the project. These impacts will
be negligible during operation
phase (Year
10) of the project upon full
establishment of the mitigation measures. These measures include
reinstatement of disturbed areas, introduction of new roadside and amenity
planting and new woodland mix planting on disturbed sloping areas and
introduction of new open spaces etc. Particularly the new planting along the viaduct alignment and
associated with station works and the provision of new landscaped open space
along the nullah will mitigate potential impacts to an extent and enhance the
industrial context within LCA6. For LCA8, the potential impact would also be alleviated to
an extent through the careful and responsive design of the bridge structure
aligned with existing Ap Lei Chau Bridge, theme noise barrier panel design and
reinstated the bridge landing area with new planting. For LCA 9, the potential construction impact will be alleviated to an extent through
the careful design, sequencing and programming of the construction works.
Following the construction phase the railway alignment will be largely
underground and areas adjacent to stations and the affected amenity area adjacent to
proposed vent building at
¡
Proposed
Upon to the completion
of construction stage of the Project, working areas, barging points and
magazine site will be reinstated to its original status, given implementation
of this measures, impacts on Chung Hom Kok Utilities Landscape (LCA 10),
Telegraph Bay Institutional Landscape (LCA 11) and Wah Kwai Utilities Landscape
(LCA 12) will be alleviated from slight to negligible level.
The negligible impact
of LCA 3 Mid-Level Upland Landscape, LCA 4 Aberdeen Country Park Landscape and
LCA 5 Shouson Hill Low-rise Residential Landscape would remain unchanged during
operation phase (Year10) of the Project. Although there is no proposed works
actually proposed in these LCA5, the Nam Fung portal/ vent building and box
structures leading to OCP Station are remote and fit into the infrastructure
landscape of Aberdeen Tunnel and its approaching road network right next to the
western lower elevation of Shouson Hill. With the full establishment of
mitigation measures, including mitigation planting with tree and bamboo
adjacent to portal/ vent building, tree planting adjacent to the box structures
and at the base of viaduct, climber plant on box structure and responsive and
innovative design of noise mitigation panels, the residual impact to these LCAs
would be negligible.
6.2.5 Residual Impact on Visual Amenity (Year 10)
Landscape and visual
mitigation measures recommended and mitigated (residual) impact for individual
VSRs assessed in Table
6.12 and summarised as
follows.
Residual Impact during
Construction Phase
Due to the scale of the
Project, even with mitigation measures implemented during construction
including preservation of existing trees, responsive hoarding, tidy site
management and careful planning of construction program, the predicted level of
impacts on the views of majority VSRs would persist due to the scale and
complexity of proposed works. These mitigation measures for construction phase
are more effective in the views of VSRs at street or lower levels and in
proximity to the works areas.
Residual Impact during
Operation Phase
Slight Adverse
The visual amenity of
users of Pao Yue Kong Swimming Pool Complex (VSR C6), users of the sitting-out
areas and playground at Heung Yip Road adjacent to the Nullah (VSRC7), Visitors
to Tai Wong Ye Temple (VSRC8), and Travellers along Heung Yip Road and Ocean
Park Road (VSRT3) and Travellers on Wong Chuk
Hang Road
(VSR T4) will be changed significantly through the
introduction of viaduct along the existing road or nullah from Ocean Park to Wong Chuk Hang. This potential visual intrusion
resulting form the railway structures will be alleviated to an extent through
the responsive design of viaduct and noise enclosure / barrier structures; and
the restoration of the disturbed areas with new amenity tree and shrub planting
beneath the viaducts; and the use of vertical greening measures where possible
on built structures. These areas will be for the use of the local community.
Although these measures will not screen views of the proposed engineering
structures the measures will soften the form of the structures and the
interface with the existing nullah; create a greater sense of visual
integration and enhance the overall landscape of the Wong Chuk Hang area. With the adoption of these
measures the potential 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).
The impacts to visual
amenity would be limited to the staff and students at elevated floors of St.
Paul’s Co-educational College Primary School (VSRO10)
arising through the introduction of the proposed Nam Fung Portal and box
structures adjacent to the school. Responsive buffer planting associated with
the proposed structures will be provided minimising the change in terms of the
character and setting of the hillside landscape. Given the combination of these
measures the potential impacts will be mitigated to a predicted slight adverse during operation
phases (Day 1 and Year 10).
The visual amenity of

will also be alleviated to an extent through responsive built structure design,
restoration of the disturbed areas with new tree and shrub planting; and the
integration of greening measures on built structures where technically
feasible.
Negligible
The majority of the
works areas will be restored following the completion of the construction works
and these proposals will be combined with new amenity areas implemented
following the sectional completion of the station and above ground structures,
and the railway alignment. Roadside tree
and shrub planting will be introduced, where space allows, and the responsive
design of built structures will be adopted.
Through the implementation of the proposed mitigation strategies the
visual intrusion of the above ground structures such as the station entrances,
vent shafts, viaduct sections, bridge, tunnel portal and plant buildings will
be significantly reduced. The moderate

to future planting areas adjacent to the proposed station entrance and vent
shafts or in an agreed off-site location (subject to the agreement of the
relevant governments). Although unavoidable there are some existing trees
required to be removed due to the works, however compensatory tree planting
will mitigate these potential impacts wherever possible.
The
mitigation measures will include restoration of the landscape with the
introduction of the proposed terraced garden/ landscape deck design, a more
sensitive and responsive and integrated design approach for the proposed vent
shafts and new station entrance with consideration of maintaining existing
underground car parking, sub station and railway facilities, in fulfillment of
FSD requirement providing continuous EVA and locate all high fire risk
components at ground floor level, these constraints shape the massing of ADM
Station extension and provide opportunities for the creation of a multi-level
greening framework for the garden. The proposed planting of new amenity trees
and shrubs to recreate the sense of visual enclosure, enhance the amenity of
the park and screen / visually soften views of the proposed ground structures.
This new planting would be integrated with the preserved trees compensating for
the loss of existing trees and reinstate its urban park landscape character.
The proposed mitigation measures would alleviate the potential visual impact
and restore the landscape framework.

vantage point (Figures 6.10.15 and 16 refer) shows the close proximity view from the

Seminary on the wooded knoll to the south of the nullah. The image shows the
scale of the viaduct above the nullah leading to WCH Station and the measures
incorporated within the design to reduce its apparent visual mass and ensure
the best possible integration with the future context. The existing context shows the linearity of
the engineered form of the nullah and the juxtaposition of the natural form of
the wooded knoll and the hard edges of the northern side of the nullah with its
industrial development.
The
VSRs with view from this location include vehicle travellers and pedestrians on
the bridge, and the workers within the adjacent industrial buildings. Their
views will be changed through the introduction of the proposed viaduct structures
above the existing nullah. Given that existing views are largely confined by
buildings and topography which line the road corridor it is important that the
proposed mitigation measures not only address the appearance of the proposed
structures but also look to enhance the adjacent landscape through the planting
of new amenity and street planting creating some visual connectivity with
landscape context of the green knoll to the south. This is achieved through the
adoption of a visually lightweight structure for the proposed viaduct and its
curvilinear form, the use of colour blocking and the abstraction of natural
colours and the tonal range of the wooded context and the use of an undulating
form for the noise attenuation structure. In addition the proposed alignment of
the viaduct structure is designed to leave the main view corridor along the
nullah intact and allow for the merging of the proposed structure with the
wooded backdrop. These measures together with the restoration of the tree and
shrub planting on the lower hill slopes below the viaduct structure will serve
to reduce the apparent visual mass of the structure; and minimise potential
visual impacts.

design to minimise the potential visual mass of the structure and reduce its
visual prominence. The scheme design has also sought to integrate the proposals
within the existing infrastructure landscape context at the approach to the
Aberdeen Tunnel.
The
existing visual amenity enjoyed by from elevated positions looking towards the
existing highway approach to the Aberdeen Tunnel portal will be changed with
the introduction of the proposed box structure, and viaduct. The proposed
landscape and visual mitigation measures include the careful and responsive
design of the tunnel portal / vent building adjacent to the built area along
Nam Fung Road, the responsive design of the box structure and viaduct following
the existing highway structures and reinstatement of the roadside planting and
the planting within the ex-Canadian Hospital site. In addition the proposed viaduct structure has
been designed to be visually lightweight reducing its visual mass relative to
the landscape of its setting and permeability of the structure allowing visual
access below the viaduct soffit. In combination these proposals will ensure
that the potential visual impacts arising from the implementation of the scheme
proposals will be minimised as far as possible both in terms of the appearance
of the structure and its visual integration within the future landscape
context.

6.3 Environmental Monitoring and Audit
The design,
implementation and maintenance of landscape and visual mitigation measures is a
key aspect and should be checked to ensure that they are fully realised, thus
EM&A for landscape and visual resources should be undertaken.
Implementation of the mitigation measures recommended shall be monitored
through the site audit programme.
6.4.1 Compatible with the Landscape Planning Framework
The proposed railway works will encroach upon a number of zoning areas
within the seven Outline Zoning Plans
which cover the proposed alignment and a small part of study area at
With the implementation
of responsive design of above ground structures with greening measures on the
built structures where condition allows in combination with the full
establishment of tree planting within the affected amenity or slope areas
together with the preserved trees and restoration of the disturbed areas
following the completion of the works, the residual impacts on the majority of
the identified landscape resources would be slight to negligible.
The creation of new open
spaces with tree and shrub planting and sitting out areas underneath proposed
viaduct will also beneficial existing landscape context along Staunton Creek

Following the planting
concepts
discussed and residual impact in Section
6.7.5 and 6.9.3, a replanting ratio of minimum 1:1 in terms of
quantity and quality except for slope works according to in accordance with ETWB TCW No. 3/2006. This tree replanting ratio would compensate the
total girth and number of tree loss within open space or in roadside amenity
area, 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 urban area. The retention of existing trees through their
preservation in-situ and transplanting and the successful establishment of the
newly planted trees will form part of the roadside and slope planting enhancing
the amenity of the local areas and providing for the thermal comfort of
pedestrians. In the wider landscape context, the green backdrop will be
reinstated upon full establishment of greening on sloping areas. The proposed
compensatory and new tree planting, which include approximately 2,000 trees in
open space and roadside planting areas and 7,360 whips on slope will utilise
both ornamental, native species and woodland mix. Semi-mature to standard sized
stock will be used to create an instant greening effect at local level. In
combination with preservation of 1,615 trees in-situ or through
transplantation, there will be a net gain of trees upon full establishment of
proposed tree planting in roadside planting and amenity area and whip planting
on sloping areas. These proposals will be subject to further development during
the detailed design stage of the project.
Given that much of the
proposed works will utilise tunnelling methods and that the proposed works areas will be
restored following the completion of the works the identified LCAs will not for the most part be
significantly impacted by the proposals. Impacts are likely to be negligible
residual impact during operational phases (Year 10) of the project for all LCAs
with full establishment of recommended landscape and visual mitigation
measures. These measures include reinstatement of disturbed areas to its
original status, introduction of new roadside and amenity planting and new
woodland mix planting on disturbed sloping areas etc.
The proposed innovative
and responsive design of the viaduct structures and their associated noise
attenuation measures, their proposed alignment and horizontal form; and the
introduction of extensive tree and shrub planting together with the preserved
trees will serve to mitigate much of the potential adverse impacts. It is likely that with the full establishment
of the proposed mitigation measures and the growth to maturity of the proposed
tree and shrub planting the proposed scheme will form a relatively small
component within the future landscape context.
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 implementation of new amenity
areas upon sectional completion of station and
railway alignment will do much to mitigate potential impacts. However the key
mitigation measure for the components of the proposed scheme has been the
adoption of innovative and responsive designs for the proposed engineering
structures including for instance the viaduct section, its associated noise
barriers and enclosure and the above ground structures associated with the
tunnel sections of the proposed alignment.
As such the level of visual
intrusion arising from the introduction of these structures further mitigated
by the proposed tree and shrub planting will therefore be alleviated to an
extent.
The visual amenity of
users of the sitting-out areas and playground at Heung Yip Road adjacent to the
Nullah (VSRC7), Visitors to Tai Wong Ye Temple (VSRC8), and Travellers along
Heung Yip Road and Ocean Park Road (VSRT3) and Travellers on Wong Chuk Hang Road (VSR
T4) will be changed significantly through the
introduction of viaduct along the existing road or nullah from Ocean Park to Wong Chuk Hang. With the adoption of responsive
design of viaduct and noise enclosure / barrier structures; and the restoration
of the disturbed areas will new amenity tree and shrub planting beneath the
viaducts; and the use of vertical greening measures where possible on built
structures, the potential residual impact to the visual amenity of these VSRs
will be mitigated to slight adverse.
The impacts to visual
amenity would be limited to the staff and students at elevated floors of St.
Paul’s Co-educational College Primary School (VSRO10)
arising through the introduction of the proposed Nam Fung Portal and railway
tunnel approach (box structures) adjacent to the school. Given the combination of buffer planting
associated with the proposed structures the potential residual impacts will be
mitigated to a predicted slight adverse.

The majority of the
works areas will be restored following the completion of the construction works
and these proposals will be combined with new amenity areas implemented
following the sectional completion of the station and above ground structures,
and the railway alignment. Roadside tree
and shrub planting will be introduced, where space allows, and the responsive
design of built structures will be adopted.
Through the implementation of the proposed mitigation strategies the
visual intrusion of the above ground structures such as the station entrances,
vent shafts, viaduct sections, bridge, tunnel portal and plant buildings will
be significantly reduced. The moderate
