13.3.1.1
Landscape and visual impacts have been assessed separately for the
construction and operation phases.
13.3.1.2
The assessment of landscape impacts has involved the following
procedures:
·
Identification of the baseline landscape resources and landscape
character areas found within the study area. This is achieved by site visit
and desktop study of topographical maps, information databases and photographs.
·
Assessment of the degree of sensitivity of the landscape resources and
landscape character areas and the classification (rating) of sensitivity and
each landscape resources and landscape character area. This is influenced by a number of
factors including:
- quality and maturity of landscape resources/characters;
- importance and rarity of special
landscape elements;
- whether the landscape resources
are considered to be of local, regional, national or global importance;
- whether there are any statutory or
regulatory limitations/requirements relating to the landscape
resources/characters; and
- ability of the landscape
resources/characters to accommodate change.
13.3.1.3
The sensitivity of each landscape resource and character area is
classified as follows:
|
High: |
Important
landscape or landscape resource of particularly distinctive character or high
importance, sensitive to relatively small changes. |
|
Medium: |
Landscape or landscape
resource of moderately valued landscape characteristics reasonably tolerant
to change. |
|
Low: |
Landscape or
landscape resource of low valued landscape characteristics highly tolerant to
change. |
·
Identification of potential sources of landscape impacts during
construction and operation phases. These are the various elements of
the construction works and operation procedures that would generate landscape
impacts.
·
Identification of the magnitude of change and the classification
(rating) of the magnitude of change for all landscape resources and landscape
character areas. The magnitude of the impact (or magnitude of change) depends on a
number of factors including:
scale of development;
- compatibility of the project with
the surrounding landscape;
- duration of impacts, i.e. whether
it is temporary (short, medium or long term), under construction and operation
phases; and
- reversibility of change.
13.3.1.4
The magnitude of landscape impacts is classified as follows:
|
Large: |
The landscape or
landscape resource would suffer major change. (beneficial or adverse) |
|
Intermediate: |
The landscape or
landscape resource would suffer moderate change. (beneficial or adverse) |
|
Small: |
The landscape or
landscape resource would suffer slight or barely perceptible change. (beneficial
or adverse) |
|
Negligible: |
The landscape or
landscape resource would suffer no discernible change. |
·
Significant threshold of potential landscape impact (before mitigation)
during construction and operation. By synthesising the magnitude of
the various impacts and the sensitivity of the various landscape resources it
is possible to categorise impacts in a logical, well-reasoned and consistent
fashion. Table 3.1 shows the
rationale for dividing the degree of significance into four thresholds, namely
insubstantial, slight, moderate, and substantial, depending on the combination
of a negligible-small-intermediate-large magnitude of impact and a
low-medium-high degree of sensitivity of landscape resource/character.

·
Identification of potential landscape mitigation measures. Mitigation measures may take the
form of
- adopting alternative design or
revisions to the basic engineering or architectural design to prevent and/or
minimize adverse impacts;
- remedial measures such as colour
and textural treatment of physical, engineering and building features; and
- compensatory measures such as the
implementation of landscape design measures (e.g. tree planting, creation of
new open space etc) to compensate for unavoidable adverse impacts and to
attempt to generate potentially beneficial long term impacts.
13.3.1.5
A programme for the mitigation measures is provided and discussed in
Section 13.7. The agencies responsible for the funding, implementation, and
maintenance of the mitigation measures are proposed in Table 7.1 and Table 7.2.
·
Significant threshold of residual impact after the implementation of
the mitigation measures during Construction and Operation: Day 1 and Year
10. The level of residual impact is
derived from the magnitude of change which the proposed works will cause to the
existing landscape resources or landscape character areas and the ability of
the LRs and LCAs to tolerate change, i.e. the quality and sensitivity of the
LRs and LCAs, taking into account the beneficial effects of the proposed
mitigation measures. The significance threshold is derived from the matrix
shown in Table 3.1.
·
Prediction of Acceptability of Impacts.
An overall assessment of the acceptability, or otherwise, of the
impacts according to the five criteria set out in Annex 10 of the EIAO TM as
below:
|
Beneficial |
The
proposed works will complement the landscape and visual character of its
setting, follow the relevant planning objectives, and improve overall and
visual quality. |
|
Acceptable |
There
will be no significant effects on the landscape, no significant visual
effects, and no interference with the key views due to the proposed works. |
|
Acceptable
with Mitigation Measures |
There
will be some adverse effects due to the proposed works, but the adverse
effects can be eliminated, reduced or offset to a large extent by the
proposed mitigation measures. |
|
Unacceptable |
There
will be the adverse effects that 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. |
13.3.1.6
The assessment of visual impacts has involved the following:
·
Identification of Zones of Visual Influence (ZVIs) during the
construction and operation phase of the project. This is achieved by site visit and
desktop study of topographic maps and photographs, and preparation of
cross-section to determine the visibility of the project from various
locations.
·
Identification of Visual Sensitive Receivers (VSRs) within the Zone of
Visual Influence (ZVIs) at construction and operation phases. These are the people who would
reside within, work within, play within, or travel through, the ZVIs.
·
Assessment of the degree of Sensitivity of the VSRs. Factors considered include:
- the type of VSRs, which is
classified according to whether the person is at home, at work, at school, at
play, or travelling. Those who view the impact from their homes are considered
to be highly sensitive as the attractiveness or otherwise of the outlook from
their home will have a substantial effect on their perception of the quality
and acceptability of their home environment and their general quality of life.
Those who view the impact from their workplace and at school are considered to
be only moderately sensitive as the attractiveness or otherwise of the outlook
will have a less important, although still material, effect on their perception
of their quality of life. The degree to which this applies depends on whether
the workplace is industrial, retail or commercial. Those who view the impact
whilst taking part in an outdoor leisure activity may display varying
sensitivity depending on the type of leisure activity. Those who view the
impact whilst travelling on a public thoroughfare will also display varying
sensitivity depending on the speed of travel.
- other factors which are considered
(as required by EIAO GN 8/2010) include the number of individuals, value and
quality of existing views, the availability and amenity of alternative views,
the duration or frequency of view, and the degree of visibility.
13.3.1.7
The sensitivity of VSRs is classified as follows:
|
High: |
The VSRs are
highly sensitive to any change in their viewing experience. |
|
Medium: |
The VSRs are
moderately sensitive to any change in their viewing experience. |
|
Low: |
The VSRs are
only slightly sensitive to any change in their viewing experience. |
·
Identification of relative numbers of VSRs. This is expressed in term of
whether there are few, medium or many VSRs in any one category of VSR.
·
Identification of potential sources of visual impacts. These are the various elements of
the construction works and operation procedures that would generate visual
impacts.
·
Assessment of the potential magnitude of visual impacts. Factors considered include
- the compatibility with the
surrounding landscape;
- the duration of the impact;
- the reversibility of the impact;
- the scale of the impact and
distance of the source of impact from the viewer; and
- potential blockage of view.
13.3.1.8
The magnitude of visual impacts is classified as follows:
|
Large: |
The VSRs would
suffer major change in their viewing experience. |
|
Intermediate: |
The VSRs would
suffer moderate change in their viewing experience. |
|
Small: |
The VSRs would
suffer small change in their viewing experience. |
|
Negligible: |
The VSRs would
suffer no discernible change in their viewing experience. |
·
Identification of potential visual mitigation measures. These may take the form of
adopting alternative designs or revisions to the basic engineering and
architectural design to prevent and/or minimise adverse impacts, remedial
measures such as colour and textural treatment of building features, landscape
and visual enhancement and tree planting to screen the roads and associated
bridge structures. A programme for the mitigation measures is provided and
discussed in Section 7. The agencies
responsible for the funding, implementation, maintenance of the mitigation
measures are identified and their approval-in-principle has been sought.
·
Prediction of the significance of visual impacts before and after the
implementation of the mitigation measures. By synthesising the magnitude of
the various visual impacts and the sensitivity of the VSRs, and the numbers of
VSRs that are affected, it is possible to categorise the degree of significance
of the impacts in a logical, well-reasoned and consistent fashion. Table 3.1 shows the rationale for
dividing the degree of significance into four thresholds, namely,
insubstantial, slight, moderate and substantial, depending on the combination
of a negligible-small-intermediate-large magnitude of impact and a
low-medium-high degree of sensitivity of VSRs.
13.3.1.9
The significance of visual impacts is categorised as follows:
|
Substantial: |
Adverse /
beneficial impact where the proposal would cause significant deterioration or
improvement in existing visual quality. |
|
Moderate: |
Adverse / beneficial
impact where the proposal would cause noticeable deterioration or improvement
in existing visual quality. |
|
Slight: |
Adverse /
beneficial impact where the proposal would cause barely perceptible
deterioration or improvement in existing visual quality. |
|
Insubstantial: |
No discernible
change in the existing visual quality. |
·
Prediction of Acceptability of Impacts. An overall assessment of the
acceptability, or otherwise, of the impacts according to the five criteria set
out in Annex 10 of the EIAO TM as below.
|
Beneficial |
The proposed works will complement the landscape and visual character
of its setting, follow the relevant planning objectives, and improve overall
and visual quality. |
|
Acceptable |
There will be no significant effects on the landscape, no significant
visual effects, and no interference with the key views due to the proposed
works. |
|
Acceptable with Mitigation Measures |
There will be some adverse effects due to the proposed works, but the
adverse effects can be eliminated, reduced or offset to a large extent by the
proposed mitigation measures. |
|
Unacceptable |
There will be the adverse effects that 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. |
13.3.1.10
It is assumed that funding, implementation and maintenance agency of the
mitigation measures can be satisfactorily resolved according to the principles
in ETWB 3/2006. All mitigation measures in this report are practical and
achievable within the known parameters of funding, implementation and
maintenance agency. The suggested agencies for the funding and implementation
(and subsequent maintenance, if applicable) are indicated in Table 7.1 and 7.2.
Approval-in-principle to the implementation and maintenance of the proposed
mitigation measures is being sought from the appropriate authorities.
13.4
Scope
and Content of the Study
13.4.1
Limits of the Study Area
13.4.1.1
The study area for the landscape impact assessment will include all areas
within 500m from the works boundary as indicated in Drawing no.
209506/EIA/LV/1101. If landscape resources at distance of about 500m are
identified to be affected by the construction and operation of the project, the
assessment area will be expanded to include LRs further outside the proposed
area. In such case, the extent of the expanded assessment area will be agreed
with EPD separately.
13.4.1.2
The area for the visual impact assessment shall be defined by the visual
envelope of the Project and associated works during the construction and
operation phases. The defined visual envelope is illustrated in Drawing
no. 209506/EIA/LV/1101.
13.4.2.1
CBL is a dual two-lane carriageway of approximately 1.8 km long across
Junk Bay to connect the proposed TKO-LTT in the west and Area 86 developments
in the east, mainly on viaduct, and connecting TKO-LTT to Wan Po Road at the
south eastern part of TKO. CBL will form a vital alternative route between
southeast TKO and Kowloon via TKO-LTT, by-passing TKO town centre. The viaduct
section of CBL has a cycle track and a footpath in addition to the road
carriageway. The proposed CBL is in relatively close proximity to the proposed
Northern Bridge (NB) and Southern Bridge (SB), which will be located at the
Eastern Channel of TKO. The project details, implementation programme,
alignment options and construction descriptions are discussed in Chapter 1-4 of
the draft EIA report, which is submitted for comments on 28 April 2011 and 8
November 2012 under letter ref. 209506/5.13/SYC/PC/HL-561 and
209506/5.13/SYC/CN-822. This assessment will cover the CBL main bridge only.
13.4.2.2
CBL will be a prominent feature seen by the developments around Junk Bay
including Area 86 and TKO town centre south, the latter being one of the
locations where the next phase of development in TKO will take place. The
Feasibility Study for Further Development of Tseung Kwan O concluded that
future development would implement a reduced development density and the
building profile will be stepped towards the waterfront.
13.4.2.3
Junk Bay is a quiet bay located to the east of Victoria Harbour. In
addition to CBL two new footbridges located at the Eastern Channel, Southern
Bridge (SB) and Northern Bridge (NB), are being planned. Since CBL is in close
proximity to SB and NB, the three bridges could be viewed as a family of
bridges and the coherency in their design will greatly enhance the townscape of
the area.
13.4.2.4
The design of CBL main bridge was selected out of several alternative
design scenarios by competition and public consultation progress. The criterion
for the selection was based on aesthetic quality, functional requirements,
buildability, operation performance and maintainability, creativity, and environmental
impact purpose. The bridge design options are described in chapter 3 of the EIA
report. There is an opportunity for the public to design CBL as a feature
bridge and a future landmark structure at TKO. The Design Ideas Invitation
Event was undertaken in year 2009. Please note for a more detailed description
of the public Design Ideas Invitation Event refer to the http://www.cbl-tko.hk/CBL-invitation/eng/
13.4.2.5
Based on the result found from Stage 3 Public Consultation held on 2012,
there is good support of the public stakeholders to the CBL project and there
are public voices for implementation of the project as quickly as possible.
13.4.3
Review of Planning and Development Control Framework
13.4.3.1
A review of the existing and planned development framework for the
proposed works and for the surroundings and the north-eastern part of Hong Kong
Island has been considered. It aims at identifying issues for the neighbouring
planned land uses, identifying potential resources and sensitive receivers, and
ensuring a high compatibility between the proposed project and the
surroundings. A desk-top study has been
undertaken of the current planning context of the waterfront portion along the
northeast part of the Hong Kong Island, in which the development along the
waterfront are the most representative group of VSRS in the study area, as it
is closest of the Hong Kong Island VSRS and will have direct view to CBL. It is noticed that the current coastal
portion of Chai Wan and Siu Sai Wan are currently occupied by the private
residential developments, such as Heng Fa Chuen on top of and adjacent to the
MTR depot and Island Resort is Siu Sai Wan.
There are no known planned new
development or redevelopment along the waterfront portion of the Chai Wan and
Siu Sai Wan that shall result in a new group of VSRS.
13.4.3.2
The Study Area for the Landscape Impact Assessment is covered by:

13.4.3.3
The review of OZP has not only included a review of the plans, but also
the Notes which form part of plan and the Explanatory Statements which
accompany the plan. Based on the Notes of the OZP para 7.4 (m), the key feature
of the new development areas proposed under the urban design framework is the
development of Cross Bay Link in the form of a landmark feature bridge.
13.4.3.4
There are natural woodland, scrubland and natural rocky shoreline of high
landscape value found within the study boundary. The proposed work will not
encroach in any Amenity Area (A), Conservation Area (CA), Green Belt (GB) and
Country Park (CP). The CBL will not affect the edge of the Clear Water Bay
Country Park (Drawing no. 209506/EIA/LV/1101 & 1102).
13.4.3.5
Study on South East New Territories Development Strategy will be reviewed
and considered. It aims to review the overall planning strategy of South East
New Territories included Tseung Kwan O district, to ensure the cultural
heritage site will not be affected.

13.4.3.6
The development of CBL in the form of a landmark feature bridge is
identified under the “Feasibility Study for Further Development of Tseung Kwan
O”, which undertaken by CEDD in 2002 and study completed in 2005, hence, it is
considered that the proposed development and associated works are in principle
following the planning intentions for the study areas as set out in the OZPs
and the Urban Design framework identified in the study. This project,
therefore, is in accordance with the planning goals and objectives for the
study area.
13.4.3.7
Several recreational facilities were also proposed in the feasibility
study, to further enhance the living environment of the TKO residents. These
include a riverside park along the Eastern Channel, a waterfront promenade in
town centre south, a water sports centre and boating facilities at the TKO
Stage I Landfill site, and the construction of more cycle tracks in the new
developments. CBL will provide a new cycle track which will be connected to the
existing and other planned cycle tracks to form a complete loop in TKO.
13.4.4.1
The CBL project is currently targeted for commissioning by 2020. To meet
this target the tentative commencement year for the construction of the CBL
would be end 2016 and would take approximately 4 years for completion (see
chapter 4 for further discussion on construction programme).
13.4.5.1
The potential concurrent projects are identified as follows and their
details are briefly discussed in the following section (refer to section 1.9.1
for comprehensive list of concurrent projects).

Tseung Kwan O – Lam Tin Tunnel
(PWP item 823TH)
13.4.5.2
With reference to the Project Profile and the EIA Study Brief
(ESB-195/2008) on TKO-LT Tunnel, the project is to construct a dual two-lane
highway connecting TKO at Po Yap Road in the east with Trunk Road T2 in Kai Tak
Development in the west and Lei Yue Mun Road Underpass. The project involves a
4.8km long highway with about 3km of the highway is in the form of tunnel. The
TKO-LT Tunnel will connect CBL to form a new external road link to meet the anticipated
traffic flow in connection with the further population intake and development
in TKO New Town. CBL project is to be implemented in parallel with TKO-TL
Tunnel Project. Cumulative landscape and visual impact due to the construction
works of TKO-LT Tunnel associated with proposed CBL will be assessed.
13.4.5.3
The TKO-LT Tunnel is to be implemented in parallel with the CBL. The
works is tentatively scheduled to commence in 2016 and be completed by 2020.
The project is anticipated in 2021.
TKO Area 86 Comprehensive
Development
13.4.5.4
Area 86 is practically being developed. According to the latest
information from MTRCL on 11 May 2009, residential and educational premises are
going to be developed in that area. Hence, these residential and educational
premises may become sensitive receivers in different construction and
operational phases. In addition, the construction in Area 86 will also have
cumulative impact on those receivers. Hence, the latest construction schedule,
plant inventory and master layout plan will be obtained from the respective
engineer of MTRCL before the commencement of the EIA to identify the likely
construction impact. A promenade along the Area 86 Development is proposed by
MTRC. The cycle track is preliminary designed to 4.5m wide. Construction of the
promenade is scheduled to commence in 2017.
Hong Kong Offshore Wind Farm in
Southeastern Waters
13.4.5.5
With reference to the Project Profile and the EIA Study Brief (ESB-
146/2006), the Project is to construct and operate a wind farm at Southeastern
water of Hong Kong. The Project component includes an installation of up to 67
wind turbines, an offshore transformer platform, sub-sea collection and
transmission cables, and Research Mast. There will be a landing cable area and
proposed cable at the west of Junk Bay connecting the collection cables from
the turbines and the CLP existing grid connection programme. The landing point
for the south of the Ocean Shores proposed location currently falls within an
area zoned “Open Space” (“O”) on the approved Tseung Kwan O Outline Zoning Plan
No. S/TKO/20. Subject to the detailed submission of the landing point, it may
require planning approval from the Town Planning Board undertaken by the CLP.
Since this project is out of scope of CBL assessment boundary, landscape impact
arising from the construction work for landing cable and laying of cable route
in Junk Bay to the landscape impact for CBL is not expected. The cumulative
landscape impact during construction is unlikely and therefore will not be
included in this landscape and visual impact assessment.
Northern & Southern Bridges
across Eastern Channel
13.4.5.6
In addition to CBL, a new cycle path cum footbridge and a new footbridge
both located at the Eastern Channel, namely existing Northern Bridge (NB) and
proposed Southern Bridge (SB) respectively. Since CBL is in close proximity to
NB and SB, the three bridges could be viewed as a family of bridges and the
coherency in their design will greatly enhance the environment in the area.
It is a
recommendation by ACABAS that the aesthetic design, appearance and structural
form of CBL are coherent with those of SB and NB. The design of NB is outside
this consultancy. NB will be procured with a design and build contractor with
construction due to start by end 2009.
The reference design, already prepared by HyD, show that NB will be a
girder bridge with arch-shaped elevation. SB being located between NB and CBL,
the design of SB is approved by ACABAS and the detail information are shown in
Appendix 13.2.

13.4.5.7
CEDD is planning to develop a comprehensive cycle track network in new
development areas of TKO, including a cycle track loop along the waterfront of
Junk Bay and the CBL with its implementation in sections in tandern with the
following infrastructure work packages or development. It includes a 5m wide
cycle track on Cross Bay Link in approximate 1.8km long on CBL to TKO town
side; and at grade section cycle track of TKO-LTT from the CBL interface to Po
Yap Road that will carry a cycle track as a continuation form that on CBL; and
approximate 1.6km long cycle tracks connecting from TKO Area 65 to Tiu Keng
Leng along waterfront at Town Centre South including adjoining footpaths and
cycle parking areas with hard and soft landscaping works; and a cycle track cum
footbridge across Eastern Channel.
Tseung Kwan O Town Centre South
Development
13.4.5.8
A town centre is planned in the central area near Tseung Kwan O Bay. The
major facilities being provided there will serve Tseung Kwan O as well as the
Sai Kung hinterland. The land-uses in the Town Centre are systematically
arranged in successive layers of housing, major government, institution or
community (GIC) facilities, commercial facilities and open space. The layering
pattern is superimposed by a cruciform plan of GIC and commercial facilities,
in form of a central north-south running GIC/open space spine and a east-west
running commercial spine of inter-linked podium structures. A town park and a
civic square are planned to the eastern fringe and near the waterfront of the
Town Centre respectively.
Tseung Kwan O Town Centre South
Development in Area 65 and 66 is currently under construction. The area will be primarily residential and
will generate VSRs in large numbers. It
is anticipated phases of the development will be in operation between 2017 and
2018.
Future Expansion of the Tseung
Kwan O Industrial Estate
13.4.5.9
Tseung Kwan O Industrial Estate is located in Area 87 in the
south-eastern part of the New Town. It is mainly intended for industries with
new or improved technology and processes which cannot operate in multi-storey
factory buildings. Further south, special industries requiring marine access
for vessels of deep draught or with potential hazards are planned in Area 137
at Fat Tong O, to take advantage of the deep waterfront and ease of marine
access via the Tathong Channel.

Physical
Landscape Resources
13.5.1.1
The study area includes the region around the Comprehensive Development
in Area 86, Industrial Estate in Area 87, sea area where the TKO-LTT created.
The proposed alignment of CBL is mainly located on the Junk Bay, surrounded by
the waterfront vegetation and extensive reclaimed flatland for future
residential development. Small portion of grassland (with tall shrubs) located
at shoreline of the surrounding Green Belt are included within the LR
assessment. The Project also covers the adjacent water bodies (Drawing no. 209506/EIA/LV/1201).
13.5.1.2
The baseline landscape resources that will be affected during the
Construction Phase and Operation Phase, together with their Sensitivity, are
described in Table 5.1. The locations of baseline landscape resources are
mapped in Drawing no. 209506/EIA/LV/1201. Photo views illustrating the

Junk Bay Coastal Landscape These landscapes consist of areas
of inshore water, found around the coastline of Junk Bay, which are enclosed
to a significant degree, by landform on three sides. The result is a coastal
landscape with a distinct sense of enclosure, characterized by the visual
interlock of land and sea. Whilst these landscapes consist predominantly of
water, they may also include small islands, occasional vessels, fish farms
and marine activities such as waterborne recreational activity. Each Bay
Landscape is given its particular character by a combination of its physical
enclosure, the character of its shoreline (and small islands or rocks
offshore) and by any marine activities. Examples of this type of landscape
are Cheung Sha in Lantau Island and Tai Long Wan in Sai Kung Junk Bay provides positive and
valuable views to adjacent receivers from Eastern District Hong Kong

Tree Survey Methodology
13.5.3.1
To minimize conflicts with existing vegetation, a full tree survey within
the CBL main alignment and landing point has been undertaken in February 2010
in accordance with ETWB TCW No. 3/2006, and the Final Tree Survey Report &
Tree Removal Application is under Appendix 13.1.
13.5.3.2
Within the designated site boundary, all living trees with a stem
diameter over 95mm measured at a point 1.3m above the ground level (hereafter
referred to as the DBH) are included in the Tree Survey as defined in the
Nature Conservation Practice Note No. 02 (Rev. June 2006) issued by AFCD.
13.5.3.3
This is to allow the fine-tuning of the design for the landscape and
ensure that any significant trees would where possible, be protected during
both the design and construction periods.
13.5.4.1
Visual Envelope of the project is bounded by the ridgeline from High Junk
Peak (Tiu Yue Yung) to the east; Mount Parker, Pottinger Peak and Mount
Collinson to the south; Lei Yue Mun and Chiu Keng Wan Shan to the west; and the
high rise residential development to the north. The ZVI adopts a cut-off at the
Tathong Channel as the only potential VSRs beyond this would be on Sung Kong
and Waglan Island from which visual impacts would be negligible due to their
distant location. The Visual Envelope of
the project is illustrated in Drawing no.

These VSRs are mapped in Drawing no. 209506/EIA/LV/1401-1405. Baseline
viewpoints from Key VSRs at district level illustrating the quality of existing
views are shown in Drawing no. 209506/EIA/LV/ 1411-1415. The baseline assessment of VSRs at district
level is shown in Table 5.2.
13.5.5.8
Some of the VSRs only have partial view to the proposed CBL works as
their views are blocked by the residential blocks along the Chui Ling Road.
Some of the VSRs at the higher-level have open full sea view to the Junk Bay.
13.5.5.9
The type of VSRs is classified according to whether the person is at
home, at work, at play, or travelling. Those who view the impact from their
homes are considered to be highly sensitive as the attractiveness or otherwise
of the outlook from their home will have a substantial effect on their
perception of the quality and acceptability of their home environment and their
general quality of life. Those who view the impact from their workplace are
considered to be only moderately sensitive as the attractiveness or otherwise
of the outlook will have a less important, although still material, effect on
their perception of their quality of life. The degree to which this applies
depends on whether the workplace is industrial, retail or commercial. Those who
view the impact whilst taking part in an outdoor leisure activity may display
varying sensitivity depending on the type of leisure activity. Those who view
the impact whilst travelling on a public thoroughfare will generally have low
sensitivity.
13.5.5.10
The sensitivity of the VSRs shall also be determined by numbers of the
individuals within the VSR category, the quality of existing views,
availability of alternative views, amenity of alternative views, degree of
visibility, duration of view and frequency of view.
13.5.6.1
The ridgeline of the High Junk Peak (Tiu Yue Yung), Miu Tsai Tun, Sheung
Yeung Shan provides a dramatic natural backdrop to the Tseung Kwan O, which
forms the valuable natural visual resources as viewed from Tseung Kwan O Town
center. The backdrop of the Junk Bay is the 615-hectare Clearwater Bay Country
Park which takes in a wide rugged terrain in the Southeastern New Territories.
The green backdrop boundaries extend southwards from Hang Hau to the undulating
mountain range that screens Joss House Bay, and continue eastwards to the
hillocks around Lung Ha Wan. Surrounding hillsides of Tiu Yue Yung and the Chiu
Keng Wan Shan create a nice picturesque scene and the long distance views to
the Tathong channel is visually pleasing.
13.5.6.2
Tathong Channel and Lei Yue Mun is a unique public asset and natural
visual resource of Tseung Kwan O, providing an open seascape along the south
coast of Tseung Kwan O.
13.5.6.3
The visual amenity of the Junk Bay variable. The western portion of the Junk Bay is characterised
by the Chiu Keng Wan Shan, Devil’s Peak and Lei Yuen Mun Point. The Northern and Eastern Portion of Junk Bay,
however, suffers from the large scale urban development and infrastructure of
the Tseung Kwan O New Town. These
introduce incoherent colours, patterns and rhythms into views. Besides, these visual qualities are being
gradually degraded by the incoherent visual features such as landfill, Tseung
Kwan O depot and incoherent residential development in Area 86. For this reason, any infrastructure
development on the eastern portion of Junk Bay will not likely to have a
significant impact on the visual system.
13.5.6.4
The western portion of Junk Bay is almost undeveloped in which the only
development is Tseung Kwan O Chinese Permanent Cemetery, and is characterised
by the visual interfaces between Chiu Keng Wan Shan ridgelines with sky and
between seashore and sea. For this
reason, any infrastructure development on the western portion of Junk Bay will
likely to have a significant impact on visual character and its visual
sensitivity is therefore high.

13.6.2.1
Tree Survey plan and tree assessment schedule for the areas where study
has been completed are shown in Appendix 13.1.
13.7.1.1
The previous sections have identified the potential landscape and visual
impacts due to the CBL. A series of mitigation measures have been formulated in
order to alleviate some of the effects of these impacts where possible, while
some mitigation measures are targeted to provide the potential landscape visual
enhancement.
13.7.1.2
The proposed landscape and visual mitigation measures for the CBL are
listed in Table 7.1 and 7.2. Generally, all mitigation measures are to be
implemented as early as possible and many of these mitigation measures perform
multiple functions.

*The magnitude of change for construction
stage and operation stage is the same unless stated otherwise
13.8.1
Potential Sources of
Visual Impacts
13.8.1.1
The sources of visual impacts due to the Project would create varying
levels of visual impact during the construction and operation phases. Potential
impacts would result from the elements stated in Section 6.1.
13.8.2
Nature and Magnitude of
Unmitigated Visual Impacts in Construction and Operation Phase
13.8.2.1
The magnitude of the impacts, before implementation of mitigation
measures, on the VSRs that would occur in the construction and operation phase
are described below and tabulated in Table 5.2. All impacts are adverse unless
otherwise stated. The residual impact significant threshold during
construction, Day 1 operation, and Year 10 operation phase are tabulated in
Table 8.1.
13.8.2.2
During the construction phase, the unmitigated visual impacts are adverse
in nature and mainly include blockage of views to the landscape resources,
degrading of visual quality of existing views and visual incompatibility of the
construction works with the surroundings. For most of the VSRs in strategic and
district levels, the magnitude of impacts is considered to be small or
negligible for the distance between the VSRs and the CBL developments is long
and the degree of visibility remains low.
13.8.2.3
For VSRs at local level, the magnitude of impacts in construction phase
varies with visual sensitivity. In general, the closer the VSRs to the
development, the larger the magnitude of visual impacts as there will be higher
potential that views from these VSRs will be fully/partially blocked by the
construction activities.
13.8.2.4
The magnitude of impacts is also considered to be large for the
residential developments along the Po Yap Road, namely, Residents of Park
Central (R4), Residents of The Grandiose
and Tseung Kwan O Plaza (R5) and Residents of Ocean Shores ( Phase I to Phase
III) (R2), as there will be direct adverse impacts.
13.8.2.5
During the operation phase, the nature of unmitigated visual impacts
could be adverse. Adverse impacts will be resulted from the blockage of views to
the landscape resources and permanent loss of panoramic seaviews. The magnitude
of adverse visual impacts is large for the highly sensitive VSRs located in
close proximity to TKO Area 65, 66, and 68 where the proposed CBL will induce
blockage of views and permanent loss of panoramic seaviews that some of these
VSRs would enjoy.
13.8.2.6
The major source of visual impacts will be the approach viaduct and the
navigation bridge from the Wan Po Road to connect to the TKO-LTT at Chiu Keng
Wan. Mitigation measures will include aesthetic design such as the use of
visually unobtrusive colours and avoidance of excessive height and bulk of
structures. Due to the high sensitivity of the VSRs located in close proximity
to TKO Area 65, 66, and 68 itself, the impact significant threshold before
mitigation will be moderate. With the implementation of mitigation measures, it
will still suffer from slight visual impact of the CBL.
13.8.2.7
During the night time, lighting provisions on the connecting roads and
the lighting glare emitted by vehicles will cause adverse impact. Therefore,
the lighting design of the main bridge will be designed to minimize the glare
at night.
13.8.2.8
In general, magnitude of adverse impacts will be reduced as the distance
between VSRs and the developments increases. Whilst the VSRs at strategic and
district levels are not that sensitive to changes in visual context induced by
the developments, the magnitude of impacts will remain small or negligible.

Prediction of
Significance of Landscape Impacts
13.9.2.1
The potential significance of the landscape impacts during the
construction and operation phases, before and after mitigation, is provided in
Table 7.4. This assessment follows the proposed methodology and assumes that
the appropriate design measures incorporated in the development layout and the
mitigation measures identified in Tables 7.1 and 7.2 would be implemented and
that the full effect of the soft landscape mitigation measures would be
realized after 10 years. Cumulative impact during construction phase and
operation phase of CBL and all concurrent projects within the assessment area
on landscape resources and landscape character areas are described below.
13.9.3
Residual Landscape Impact
in Construction Phase
13.9.3.1
Based on the tree survey report on CBL, approximately 308 no. of trees
will be affected, of which approximately 58 no. are proposed to be
transplanted, and approximately 250 no.
trees are proposed to be felled (including 190 no. Leucaena leucocephala and 60 no. common trees). Due to construction
of the CBL, it is unavoidably considered to remove the affected trees.
13.9.3.2
Trees surveyed within the proposed works boundary are primarily common species.
There are no LCSD Champion Trees, Registered Old and Valuable Trees nor trees
that meet the criteria for Important Trees (ITs) as listed in ETWBTC(W) 3/2006.
There are no tree species listed under Forests and Countryside Ordinance (Cap.
96); and Protection of Endangered Species of Animals and Plants Ordinance(Cap.
586).
13.9.3.3
In accordance with ETWB TC(W) No.
3/2006, the proposed compensatory planting proposal should be of a ratio not
less than 1:1 in terms of quality and quantity within the site. For the
proposed trees to be felled, heavy standard trees with trunk diameter from 75mm
to 150mm (as specified in the Clause 3.15 of General Specification of Civil
Engineering Works 2006) will be adopted for compensatory planting. It is
expected approx. 67 heavy standard sized trees shall be planted as compensatory
tree planting within the site boundary of the proposed works.
13.9.3.4
Cumulative impact on existing trees is summarized in Table 9.2, and final
tree removal report is under Appendix 13.1.

approximately 308 no. of trees will be affected, of
which approximately 58 no. are proposed to be transplanted, and approximately 250 no. trees are proposed to
be felled (including 190 no. Leucaena leucocephala and 60 no. common trees) |
13.9.3.5
There will be permanently loss of 800 sq.m. seawater body, which accounts
for 0.05% of the sea water body in the study area, in Junk Bay due to the
construction of CBL 10 no. approach piers and 2 no. main bridge piers. The landscape impacts on Seawater body (LR01)
can only be slightly mitigated by minimizing area and construction period. Due
to the abundance of sea water, therefore, it is considered that the landscape
impacts on LR01 are slight with the implementation of mitigation measures.
13.9.3.6
There will be no impact on existing open space, stream course, SSSI,
Green Belt area in Chiu Keng Wan Shan and Clear Water Bay Country Park due to
the construction of CBL.
13.9.3.7
The residual impact on other LRs and LCAs will be mostly insubstantial,
except on LR03, LCA01 and LCA02 will be slight.
13.9.3.8

It is considered that the residual impact on this LCA is slight.
13.9.4.4
LCA02 - There will be slight impact on Reclamation / Ongoing Major
Development Landscape due to the operation of CBL. However, with the proposed
mitigation measures including the aesthetic design of the built structures and
soft landscape treatment works, it is considered that the residual impact on
this LCA is insubstantial.
13.9.4.5
LCA03 – Tseung Kwan O Industrial Urban Landscape will be subject to
insubstantial impact as this LCA is relatively far away from the CBL.
13.9.4.6
LCA04 – Chiu Keng Wan Coastal Upland and Hillside Landscape will be
subject to insubstantial impact as this LCA is relatively far away from the
CBL. However, this LCA will definitely be affected by the interface project : TKO-LTT.

lost due to the construction of the piers for CBL bridge. It is considered that
the residual impact is expected to be slight.
13.9.4.12
LR2 – there is expected to be negligible impact upon the Landscaped Area
and Plantation within High-rise residential development in CDA 86 (LOHAS Park).
It is considered that the residual impact is expected to be insubstantial.
13.9.4.13
LR3 – approximately 308 no. of trees will be affected, of which
approximately 58 no. are proposed to be transplanted, and approximately 250 no. trees are proposed to
be felled (including 190 no. Leucaena leucocephala and 60 no. common trees).
Proposed compensatory planting is proposed to comepsate for the loss. It is
considered that the residual impact is expected to be insubstantial.
13.9.4.14
LR4 – there is expected to be negligible impact upon the Plantation
within Vacant land (LR4). It is considered that the residual impact is expected
to be insubstantial.

LR13 – there is expected to be negligible impact upon Seawall in Tseung Kwan O Industrial Estate. It is considered that the residual impact is
expected to be insubstantial.
13.9.4.24
Therefore, the overall cumulative residual impacts on existing trees are
considered acceptable with mitigation measures.
13.9.5
Residual Visual Impact in
Construction Phase
13.9.5.1
Given the distance and location of the VSRs at strategic and district
levels are generally far away from the development, the adverse residual
impacts are expected to be slight or insubstantial with the implementation of
appropriate mitigation measures.
13.9.5.2
Hikers along High Junk Peak (Tiu Yue Yung) in Clear Water Bay Country
Park (S2), Visitors/Hikers at Mount Parker (S5), Visitors/Hikers at Pottinger
Peak (S6), Visitors/Hikers at Mount Collinson (S7) and Visitors/Hikers at Black
Hill (S8) will have intermittent and direct views to the construction works of
CBL. The distance and topography means that the views will be rare. They will
also look down onto the Junk Bay that has already been significantly developed
with high-rise residential blocks. There is expected to be small magnitude of
change after mitigation with residual impact significance being slight.
13.9.5.3
At local level, VSRs abutting the project boundary of CBL will be subject
to moderate residual visual impacts during the construction phase. With the implementation
of appropriate mitigation measures like incorporation of decorative hoarding,
the residual visual impacts will be lowered to slight level. For residents in Tseung Kwan O CDA (CDA1) and
Residents of Ocean Shores ( Phase I to Phase III), the residual impacts are still
considered to be moderate given their high sensitivity, close proximity to the
source of impacts and the Road D9 noise barrier effect on their perception of
the visual quality.
13.9.5.4
Other local VSRs further away will only have partial or glimpse views to
CBL. Therefore, the residual impacts will be slight after implementation of
mitigation measures.
For Planned VSRs, Planned Residential area of TKO Area 65, 66 and 68 (R7) and Planned
visitor and residents in commercial development with Public Transport
Interchange (OU2), the residual impacts are considered to be moderate during
its close and direct views towards the structure of the CBL.
13.9.6
Residual Visual Impact in
Operation Phase
13.9.6.1
Residual impact on VSRs are shown in Table 8.1 and mapped in Drawing no.
209506/EIA/LV/1631 and 1633.
13.9.6.2
For VSRs at district levels, the direct sea view from Island Resort
Residential Area and Visitors in Siu Sai Wan Promenade and Sports Ground (D2),
and Heng Fa Chuen Residential Area (D1) and Logistics Centre and Preliminary
Treatments Works and Cargo Handling Basin (D4) will be changed from open
seaview to partial blockage by CBL. Given the long distance, the residual
visual impact is considered as slight with the implementation of the
appropriate mitigation measures. Workers
in the TKO Industrial Estate (D3) will have intermittent and distant views of
the CBL, hence the residual visual impact during operation phase is
insubstantial.
13.9.6.3
For VSRs at strategic levels, the view from Lei Yue Mun Holiday Village
and Lei Yue Mun Park, and Hong Kong
Museum of Coastal Defence (S1), Lei Yue Mun and Tathong Channel (S3) and Wilson
Trail (near Devil’s Peak of Lei Yue Mun) (S4) will be changed from open seaview
to partial blockage by the CBL. However, as S1, S3 and S4 will have alternative
view and sightseeing, it is considered that the residual visual impacts during
operation phase are slight.
13.9.6.4
Viewpoint along the High Junk Peak (Tiu Yue Yung) in Clear Water Bay
Country Park (S2) and along Black Hill (S8) is approximately 1500m and 2000m respectively
from the CBL. The existing Junk Bay will be slightly blocked by the CBL, while
the open seaview across the Tathong Channel will not be affected, hence the
residual visual impact during operation phase is insubstantial.
13.9.6.5
Visitors/Hikers at Mount Parker (S5), at Pottinger Peak (S6), and at
Mount Collinson (S7) are approximately
4500m from the CBL. Visitors will look
down onto the Junk Bay that has already been significantly developed with
residential blocks, hence the residual visual impact during operation phase is
insubstantial.
13.9.6.6
At local level, for VSRs in close proximity to CBL, including residents
or workers in Tsueng Kwan O Comprehensive Development Area 86 (CDA1), Residents
of Bauhinia Garden (R1), Residents of
Ocean Shores ( Phase I to Phase III) (R2), Residents of Metro Town (R3),
Residents of Park Central (R4),
Residents of The Grandiose and Tseung Kwan O Plaza (R5), Residents of Oscar By
the Sea (R6) , the residual impacts are expected to be from moderate to slight.
There will inevitably be permanent loss of open seaview in Junk Bay and
obstruction of existing bay view, even with the implementation of mitigation
measures.
13.9.6.7
For the commercial development with PTI along Po Yap Road (OU 2),
recreational users in TKO Stage I Landfill (REC 1), proposed “Central Avenue”
in Town Centre South near the promenade in open space of TKO Area 68 and the
promenade user in the former TKO Stage I Landfill site (O1), along the
waterfront near the Eastern Channel in open space of TKO Area 68 (O2), and
proposed Open Space in Area 74 (O3), the residual impacts are expected to be
slight after the implementation of mitigation measures. There will inevitably
be permanent loss of open panoramic seaview, obstruction of existing views and
reduction of depth of view, even with the implementation of mitigation
measures. In particular, the visual impact of the pier structure cannot be
softened because soft landscape treatment cannot be installed over there. Its
visual impact can only be slightly minimized by aesthetic design such as the
use of visually unobtrusive colours and avoidance of excessive height and bulk
of structures.
13.9.6.8
Photomontages showing visual impact on representative VSRs due to the
development and the view point plans are shown in Drawing no.
209506/EIA/LV/1700 to 209506/EIA/LV/1709. Their residual impacts are assessed
and summarized as below:-
13.9.6.9
Viewpoint from Residents of Park Central (R4) is approximately 1100m from
the CBL (Drawing no. 209506/EIA/LV/1701).
The existing open seaview will be partially blocked by the proposed CBL,
TKO-LTT. With the implementation of mitigation measures, including aesthetic
treatment to the engineering structures, the residual visual impact is
considered as slight.
13.9.6.10
Viewpoint along Wilson Trail (S4) (near Devil’s Peak of Lei Yue Mun) is
approximately 1000m from the CBL (Drawing no. 209506/EIA/LV/1702). The existing
open seaview will be partially blocked by the proposed CBL, TKO-LTT. Since the
VSR will only have alternative view and only occasional view towards the Junk
Bay, the residual visual impact is considered as slight.
13.9.6.11
Viewpoint from Planned Travellers of CBL and TKO-LTT (T3) is shown in
Drawing no. 209506/EIA/LV/1703. With the implementation of shrub planting and
aesthetic treatment, the residual visual impact is considered as insubstantial.
13.9.6.12
Viewpoint from Tsueng Kwan O Comprehensive Development Area 86 (CDA1) is
approximately 100m from CBL (Drawing no. 209506/EIA/LV/1704), and the viewpoint
from Planned VSRs in the TKO Area 65, 66, 68 (R 7) is directly facing towards
the proposed CBL. The existing Junk Bay seascape will be obstructed by the CBL,
Road D9 approach viaduct and associated noise mitigation measures. The proposed
mitigation measures and aesthetic design will be incorporated to all
developments, and associated facilities; however, due to the close proximity to
the CBL, the residual visual impact is considered as moderate.
13.9.6.13
Viewpoint along High Junk Peak ( Tiu Yue Yung) in Clear Water Bay Country
Park (S2) is approximately 2000m from the CBL (Drawing no. 209506/EIA/LV/1705).
The existing open seaview will be partially blocked by the proposed CBL,
TKO-LTT. Since the VSR will only have alternative view and only occasional view
towards the Junk Bay, the residual visual impact is considered as insubstantial.
13.9.6.14
Viewpoint from Residents of Heng Fa Chuen Residential Area (D1) and
Island Resort Residential Area and visitor in Siu Sai Wan Promenade and Sports
Ground (D2) are approximately 3000m from the CBL (Drawing no.
209506/EIA/LV/1706 & 1707 series). The existing open seaview will be
partially blocked by the proposed CBL, TKO-LTT. With the implementation of
mitigation measures, including aesthetic treatment to the engineering
structures, the residual visual impact is considered as slight.
13.9.6.15
Workers in the Creative Secondary School (GIC5) will have intermittent
views to the CBL, which will mostly screened by the residential development of
Oscar By the Sea on its western side, therefore, the residual impact are
considered as slight.
13.9.6.16
Workers in the Tseung Kwan O Methodist Primary School and Evangel College
(GIC2), P.O.H. 80th Anniversary Tang Ying Hei College, C.&M. A.
Sung Kei Secondary School, Yan Chai Hospital Wong Wah San Secondary School and
Yan Oi Tong Tin Ka Ping Primary School (GIC3), Hong Kong Design Institute
Campus (GIC4), and Planned GIC development of TKO area 67, Area 72 and Area 74
(GIC6) will have intermittent views to
the CBL which will be mostly screened by the residential development in Area
65, 66 and 68, thus, the residual development are considered as slight.
Travellers of Wan Po Road (T1)
and travellers of TKO station and PT1 in the junction of Tong Tak Street and
Tong Chun Street (T2) will have intermittent views to the CBL. Views from the TKO station will more likely be
dominated by residential development in Area 65, 66 and 68, while views from
the Wan Po Road will be dominated by the high-density residential development
in Area 86. Therefore, the residual
visual impact is considered as insubstantial; workers in the Tseung Kwan O
Sewage Treatment Works, Bus depot in TKO Area 85 and Tseung Kwan O Stage II and
III Landfill area (GIC1), Planned high-rise residential uses along Shek Kok
Road in Area 85 (GIC8), Planned Fire Services Training School cum Driving
School, and the proposed private hospital and Area 78 (GIC7), and workers at
Hong Kong Movie City (GIC9) will have intermittent views to the CBL. Views will be blocked by the high-density
residential development in Area 86 and therefore, the residual impact are
considered as insubstantial.
Workers in the TKO Industrial
Estate Extension will have intermittent and direct view of the CBL. Therefore, the residual impact is considered
as insubstantial.
Workers in the planned high-rise
residential uses along Shek Kok Road in Area 85 (GIC8), and workers at Hong
Kong Movie City (GIC9) will have intermittent views to the CBL. Views will be locked by the high-density
residential development in Area 86 and therefore, the residual impact are
considered as insubstantial.
Visitor and residents in commercial
development in PT1 (OU2) will have intermittent views to the CBL. However, views towards CBL will be blocked
and are likely be dominated by the residential development on its southern
side. Therefore, the residual visual
impact is considered as slight.
Visitors of Junk Bay Chinese
Permanent Cemetery (OU1) will have direct and close view to CBL and Junk
Bay. However, majority of visitors walk
in this area during Ching Ming Festival and Chung Yeung Festival only. Therefore the residual visual impact is
considered as slight.
13.10.1.1
The proposed development and associated works follow in principle the
planning intentions from the approved Tseung Kwan O – Outline Zoning Plan
(S/TKO/20). However, the scale of CBL
together with concurrent projects, namely, TKO-LTT will inevitably result in
some landscape and visual impacts.
13.10.1.2
Based on the tree survey report on CBL, approximately 308 no. of trees
will be affected (LR3), of which approximately 58 no. are proposed to be
transplanted, and approximately 250 no.
trees are proposed to be felled (including 190 no. Leucaena leucocephala and 60
no. common trees). Due to construction of the CBL, it is unavoidably considered
to remove the affected trees. Affected trees with high to medium amenity value
and medium survival rate are proposed to be transplanted. Trees surveyed within
the proposed works boundary are primarily common species. There are no LCSD
Champion Trees, Registered Old and Valuable Trees and Protected Species under
Cap 586 Protection of Endangered Species of Animals and Plants Ordinance. It is
expected approx. 67 heavy standard sized trees shall be planted as compensatory
tree planting. The overall residual impact on trees is considered as acceptable
with mitigation measures.
13.10.1.3
There is expected to be some minor impact upon the sea waterbody in Junk
Bay (LR1). The sea water body will be
permanent lost due to the construction of the piers for CBL bridge. Residual
impacts after 10 years of operation are expected to be slight.
13.10.1.4
There is expected to be negligible impact upon the Landscaped Area and
Plantation within High-rise residential development in CDA 86 (LOHAS Park)
(LR2). It is considered that the residual impact is expected to be
insubstantial.
13.10.1.5
There is expected to be negligible impact upon the Plantation within
Vacant land (LR4), It is considered that the residual impact is expected to be
insubstantial after year 10.
13.10.1.6
There is expected to be negligible impact upon Plantation within
Industrial Building (LR5). Residual
impact after Year 10 is expected to be insubstantial.
13.10.1.7
There is expected to be negligible impact upon Woodland at Foothill and
Hillside (LR6). Residual impact after Year 10 is expected to be insubstantial.
13.10.1.8
There is expected to be negligible impact upon Grassland and Scrubland at
Hillside in Chiu Keng Wan (LR7). Residual impact after Year 10 is expected to
be insubstantial.
13.10.1.9
There is expected to be negligible impact upon Vegetation of clustered
newly planted trees and shrubs scattered on Tseung Kwan O Stage II and III
Landfill Area (LR8). Residual impact after Year 10 is expected to be
insubstantial.
13.10.1.10
There is expected to be negligible impact upon Nature Rocky and Sand
Shoreline in Chiu Keng Wan (LR9) and Plantation at Wasteland / Construction
Area in Chiu Keng Wan (LR10). Residual impact after Year 10 is expected to be
insubstantial.
13.10.1.11
There is expected to be negligible impact upon Vegetation along the
Coastline Adjacent to Lohas Park Road (LR11). Residual impact after Year 10 is
expected to be insubstantial.
13.10.1.12
There is expected to be negligible impact upon Roadside Planting in Lohas
Park Road (LR12). Residual impact after Year 10 is expected to be
insubstantial.
13.10.1.13
There is expected to be negligible impact upon Seawall in Tseung Kwan O
Industrial Estate (LR13). Residual impact after Year 10 is expected to be
insubstantial.
13.10.1.14
With the proposed mitigation measures including the compensatory planting
and aesthetic treatments, the Junk Bay Coastal Landscape (LCA 1) will still
suffer from slight landscape impact during construction and operation due to
the artificial engineering structure which is incompatible with the natural
Junk Bay character.
13.10.1.15
LCA2 - There will be slight impact on Reclamation / ongoing major
development landscape due to the operation of CBL. However, with the proposed
mitigation measures including the aesthetic design of the built structures and
soft landscape treatment works, it is considered that the residual impact on
this LCA is insubstantial.
13.10.1.16
LCA3 – Tseung Kwan O Industrial Urban Landscape will be subject to
insubstantial impact as this LCA is relatively far away from the CBL.
13.10.1.17
LCA4 – Chiu Keng Wan Coastal Upland and Hillside Landscape will be
subject to insubstantial impact as this LCA is relatively far away from the
CBL. However, this LCA will definitely be affected by the interface project : TKO-LTT.
13.10.1.18
LCA5 – Tseung Kwan O Landfill Landscape (Stage II and III) will be
subject to insubstantial impact as this LCA is relatively far away from the CBL
and will not be affected.
13.10.1.19
LCA6 – Tseung Kwan O Miscellaneous Urban Fringe Landscapewill be subject
to insubstantial impact as this LCA is relatively far away from the CBL and
will not be affected.
13.10.1.20
LCA7 – High Junk Peak Coastal Upland and Hillside Landscape will be
subject to insubstantial impact as this LCA is relatively far away from the CBL
and will not be affected.
13.10.1.21
LCA8 – Residential Urban Fringe Landscape will be subject to
insubstantial impact as this LCA is relatively far away from the CBL and will
not be affected.
13.10.1.22
Lei Yue Mun and Tathong Channel are a unique public asset and natural
visual resources as viewed from Shau Kei Wan, Heng Fa Chuen and Siu Sai Wan,
providing an open seascape along the Junk Bay. The proposed CBL, particularly
the pier structure will induce partial blockage of views and permanent loss of
open seascape view. Residents in TKO
Area 86 (CDA1) will have direct, short range views to the new road which is
immediately adjacent to or very close to several receivers. The cumulative
visual impacts can only be slightly mitigated by minimizing area, avoidance of
excessive height and bulk of buildings and structures and construction period.
Therefore, the VSRs (CDA1) located in close proximity to CBL will still suffer
from moderate residual visual impact of the CBL and TKO LTT.
13.10.1.23
The Planned proposed “Central Avenue” user in Town Centre South near the
promenade in open space of TKO Area 68 and the promenade user in the former TKO
Stage I Landfill site (O1), the Planned waterfront near the Eastern Channel in
open space of TKO Area 68 (O2), and Planned
Residential area of TKO Area 65, 66 and 68 (R7) will have direct and close range
views to the CBL and TKO-LTT. The
cumulative visual impacts can only be mitigated by using visually unobtrusive
building material and refinement of engineering design. Screening planting/amenity planting in the
open space itself is expected to have minor screening effect to these views
because the CBL are elevated. Therefore,
the VSRs (O1, O2 and R7) will still suffer from moderate residual visual impact
of the CBL and TKO-LTT.
The proposed Open Space in Area
74 (O3), and Planned recreational users in TKO Stage I Landfill (REC1), the
residual impact would be slight due to screening/amenity planting along the
waterfront promenade will be fully established and is expected to have
screening effect on the CBL and TKO-LTT.
Residents of Ocean Shores (R2) will have direct, close views to the new
CBL and TKO-LTT which is immediately adjacent or very close to the VSRs. Mitigation in the form of screening planting,
refinement of structure and architectural design of road structures will help
in reducing these visual impacts.
However, the VSRs will still be subject to the partial blockage of views
and permanent loss of open seaview.
Therefore, the VSRs (R2) will still suffer from moderate residual visual
impact of CBL and TKO-LTT.
13.10.1.24 The landscape and visual impact assessment has been conducted according to the criteria and guidelines for evaluating and assessing impacts as stated in Annex 10 and 18 of the TM-EIAO, it is considered that the identified residual impacts, taking account of both importance and degree of compliance, will be acceptable with mitigation measures.
