7.1
This
Landscape and Visual Impact Assessment (LVIA) covers the proposed Atrium Link
Extension of Hong Kong Convention and Exhibition Centre (HKCEC) in Wan Chai
North. The project proponent is Hong Kong Trade Development Council (TDC). This section assesses the potential landscape
and visual impact due to the construction and operation of the proposed work in
accordance with the Environmental Impact Assessment Ordinance (EIAO).
7.2
Existing
HKCEC consists of three major components, i.e., Phase 1, Phase 2 and the Atrium
Link found in between these Phases.
Phase 1 is commonly known as “Old Wing” while Phase 2 as “New
Wing”. Local people of

Review of Planning and Development Control Framework
7.4
A review
of the existing and planned development framework for the proposed works and
for the surroundings has been considered. It aims to identify issues for the
neighbouring planned land uses, to identify potential resources and sensitive
receivers, and to ensure a high compatibility between the proposed project and
the surroundings.
7.5
Wan Chai
North Outline Zoning Plan (OZP) No. S/H25/1 has been examined. The area near the waterfront is dominated by
patches of Other Specified Use (OU), suggesting the sensitive nature and
planning of the area. The Plan shows
possible developments, including the provision of Open Spaces (O) to the east
and to the west of the existing HKCEC “New Wing”. It also shows the proposed relocation of Wan
Chai Ferry Pier and the planning of a large Comprehensive Development Area
(CDA) on the existing bus terminal to the south of Wan Chai Ferry Pier. Although the Plan has been made statutory
under the Town Planning Ordinance, it shall by no means be considered a
consolidated plan due to the strong public criticisms and juridical reviews in
recent years. Intended land use pattern
extracted from the Plan is shown on Figure 7.2.
7.6
The
existing area of HKCEC Atrium Link has been zoned as OU. Part of the proposed Atrium Link Extension
falls within the area designated as ‘Road’ on the Wai Chai North OZP which
requires planning permission from the Town Planning Board (TPB) according to
Section 16 of the Town Planning Ordinance.
An application to TPB has already been approved earlier to expand the
area to suit the intended Atrium Link Extension.
7.7
Major
waterfront development projects have been previously planned along the
waterfront near Wan Chai, including:
- Wan
Chai Development Phase II (WDII)
- Central
Wan Chai Bypass (CWB) and Road P2
These projects are somewhat interlinked because they require a
prerequisite of consolidated planning of reclamation from Central to

Methodology of Assessment of Landscape Impacts
7.9
The
assessment of landscape impacts has adopted the following process:
·
Identification
of the baseline Landscape Resources (LR) and Landscape Character Area (LCA)
found within the study boundary defined by EPD’s Study Brief. This was firstly prepared by desktop research
study on aerial photos and topographical maps, then by site visits and
photo-retaking for verification.
·
Assessment
of “Sensitivity to Change” to the LR and LCA.
This is affected by factors including:
(i) whether the resource is common or rare; (ii) whether it is
considered to be of local, regional, national or global importance; (iii)
whether there are any statutory or regulatory limitations / requirements
relating to the resource; (iv) the quality of the resource; (v) the maturity of
the resource, and (vi) the ability of the resource to accommodate changes. The
sensitivity of each LR and LCA is separated into construction phase and
operation phase. The rating is classified as below:
High: Important LR or
LCA of particularly distinctive characteristics or high importance, and is
sensitive to relatively small changes
Medium: LR or LCA of moderate
landscape characteristics and value, and is reasonably tolerant to change
Low: LR or LCA with
low landscape characteristics and value, and is largely tolerant to change
·
Assessment
of “Magnitude of Change” for landscape impacts.
This is affected by factors including:
(i) the physical extent of impact; (ii) the landscape context of impact
and (iii) the time-scale of impact, such as whether it is temporary (short,
medium or long term), permanent with reversible potentials, or irreversibly
permanent. Magnitude of Change is
separately considered for construction phase and operation phase. For operation phase, it is further divided
into a scenario with all adjacent waterfront developments (i.e., Road P2, WDII
etc.) to be constructed and another scenario without these developments. The assessment for these scenarios, however,
still refers to the magnitude of change arisen from the operation of the
proposed Atrium Link Extension itself with all these developments in the
background/ context. The rating for
“Magnitude of Change” is classified as below:
Large: LR or
LCA will suffer a major change.
Intermediate: LR or LCA
will suffer a moderate change.
Small: LR or
LCA will suffer a barely perceptible change.
Negligible: LR or
LCA will suffer no discernible change.
·
Assessment
of the “Impact Significance Threshold Before Mitigation” for landscape
impacts. The assessment of landscape
impacts during construction, during operation with or without all adjacent
waterfront developments is produced by synthesizing the “Sensitivity to Change”
and “Magnitude of Change” for various LR and LCA according to Table 7.1.
The degree of significance is divided into four thresholds, depending on
the combination:
Substantial: Adverse
/ beneficial impact where the proposal will cause significant deterioration or
improvement in existing landscape quality
Moderate: Adverse / beneficial
impact where the proposal will cause a noticeable deterioration or improvement
in existing landscape quality
Slight: Adverse / beneficial
impact where the proposal will cause barely perceptible deterioration or
improvement in existing landscape quality
Insubstantial: No discernible change in
the existing landscape quality

Identification
of potential Mitigation Measures. This
part is also separated into construction phase and operation phase, with
proposing measures for preventing or minimizing unavoidable adverse impacts and
/ or generating beneficial long-term impacts.
A table for the mitigation measures is provided. The agencies responsible for the funding/
implementation and management/ maintenance of the mitigation measures are also
identified.
·
Identification
of “Residual Impact Significance Threshold After Mitigation” for landscape
impacts. This part indicates the
accumulative influence to LR and LCA after applying mitigation measures, with
an assumption that all proposed measures and guidelines will be fully
implemented. Like the “Impact Significance
Before Mitigation”, the rating has been divided into the construction phase and
operation phase.
Methodology of Assessment of Visual Impacts
7.10
The
assessment of visual impacts has adopted the following process:
·
Identification
of Zones of Visual Influence (ZVI) and Visually Sensitive Receivers Groups
(VSRs) during construction and during operation. A ZVI has been established by
a desktop study of topographic maps, street maps, photographs and site visits
to determine the possible VSRs in the Harbour area.
·
Assessment
of the “Sensitivity to change” of the VSRs.
Factors include:
-
The type of VSRs, such as viewers who are hotel guests,
workers, road travellers or recreation engagers. Those people viewing from the hotels are
considered to be highly sensitive because the view directly affects their
general quality of daily life during their stay there. Those people viewing from their workplace are
considered to be only moderately sensitive as it is less important factor for
their quality of life. The degree however depends on whether the workplace is
industrial, retail or commercial. Those
people who take part in outdoor leisure activity may have varying sensitivity
depending on the type of recreation.
Those people who are travelling on roads or streets will also have
varying sensitivity depending on the speed of travel.
-
Population of viewers.
This is to consider the overall population of viewers in the VSRs.
-
Other factors to be considered (as required by EIAO GN
8/2002) include the value and quality of existing views, the availability and
amenity of alternative views, the duration and frequency of view, and the
degree of visibility.
7.11
“Sensitivity
to change” of the VSRs is divided into construction phase and operation phase,
with rating classified as below:
High: The VSR is
highly sensitive to any change in their viewing experience.
Medium: The VSR is moderately
sensitive to any change in their viewing experience.
Low: The VSR is only
slightly sensitive to any change in their viewing experience.
·
Assessment
of the potential “Magnitude of Impact”.
Factors 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
-
the degree of visibility of the impact, and the degree to
which the impact dominates the field of vision of the viewer.
7.12
The
magnitude of visual impacts during different stages of construction and during
operation has also been separately considered, with rating as below:
Large: The
VSRs would suffer a major change in their viewing experience.
Intermediate: The VSRs
would suffer a moderate change in their viewing experience.
Small: The
VSRs would suffer a small change in their viewing experience.
Negligible: The
VSRs would suffer no discernible change in their viewing experience.
·
Prediction
of “Impact Significance Threshold Before Mitigation” for visual impacts. Same as that for the landscape impact
assessment, it aims to synthesize the “Sensitivity to Change” and “Magnitude of
Change” for various VSRs according to Table 7.1 to assess the visual impacts in a matrix. The degree of significance has been divided
into four thresholds again:
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 a 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
·
Identification
of potential Mitigation Measures. This
part is also separated into construction phase and operation phase, with
proposing measures for preventing or minimizing unavoidable adverse impacts and
/ or generating beneficial long-term impacts.
A table for the mitigation measures is provided. The agencies responsible for the funding/
implementation and management/ maintenance of the mitigation measures are also
identified.
·
Identification
of “Residual Impact Significance Threshold After Mitigation” for visual
impacts. This part indicates the
accumulative influence to VSRs after applying mitigation measures, with an
assumption that all proposed measures and guidelines will be fully
implemented. Like the “Impact
Significance Before Mitigation”, the rating has been divided into the
construction phase and operation phase.
·
Preparation
of Photomontage. To illustrate and
compare the visual impact of proposed redevelopment with and without
mitigation, computer-simulated views from selected VSRs to the proposed Atrium
Link Extension have been generated. Due
to the urban context, nature of the proposed works and the relative little use
of vegetation as mitigation, the photomontages after mitigation at Day 1 and at
Year 10 will be very similar. Thus,
those at Year 10 will not be provided in this report.
7.13
Landscape baseline review comprises of the identification of all
existing Landscape Resources (LR) and Landscape Character Areas (LCA) within
7.14
Due to the urban context of the Study Area, there are limited typologies of
landscape resources found. The nature of
landscape resources, such as existing plant species, is also quite
similar. They are differentiated mostly
due to their different quality of planting and their correlation to the overall
landscape characters of Wan Chai north:
LR1 – Urban Waterfront and Harbour
7.15
The manmade waterfront forms part of the greater
LR2 – Urban Street/ Amenity Planting
7.16
This LR refers to street planting or amenity planting
within private lot boundaries along streets.
The trees are mostly of medium size and of common ornamental species,
such as Bauhinia spp., Ficus spp., Hibiscus tiliaceus, Acacia confusa,
Cinnamomum spp., with occasional
small palms. Their conditions are
generally fair if along street but better if within private lots. Some existing trees and palms along
LR3 – Urban Open Space
7.17
This LR refers to open spaces, including semi-public
(i.e., privately maintained but open to public) or private (i.e., access is
controlled). Except for the private
swimming pool found at the podium of HKCEC Old Wing, the spaces are generally
for passive use, characterized by ornamental planting and seating only. These spaces contribute a significant portion
of planting areas found in Wan Chai north.
The planting is of high amenity value, and is well-maintained. The trees are generally of medium sizes and
of good to fair condition. There is more
species variety in this LR, but the plants remain as common ornamental species
of both native and exotic species.
7.18
There is no ‘Champion Trees’ and ‘Old and Valuable
Trees’ identified within the Study Area.
All trees are planted ornamental ones of small to medium size and of a
mix of native and exotic species.
7.19
The Study Area is located in waterfront of Wan Chai
North. The overall landscape character
is dominated by manmade, urban context with HKCEC “New Wing” as one of the
iconic architecture of
LCA1 – HKCEC “New Wing”
7.20
The dominant feature of this LCA is the HKCEC “New
Wing”, which is considered as an important landmark of
LCA2 – Sea Channel Space
7.21
This area is dominated by a sea channel underneath the
existing HKCEC Atrium Link between the “New Wing” and the “Old Wing”. With some above-ground seawater intake/
pumping structures and a good visual connection to the more ‘attractive’ “New
Wing”, this LCA appears to be an intermediate space that people are not
supposed to linger. The space may consider
as an auxiliary or ‘leftover’ space and has significantly less active
pedestrian flow.
LCA3 – Transport Node
7.22
This LCA is dominated by a transportation interchange
in which Wan Chai Ferry Pier, a bus terminal, and
LCA4 – Wan Chai North Commercial
7.23
This LCA is dominated by tall commercial buildings,
including HKCEC “Old Wing”, with some associated passive open spaces, which
contributes to most greening for Wan Chai North. There is a clear separation of pedestrian and
vehicular flow, where heavy pedestrian flow takes place on elevated walkways
interlinking and within the commercial buildings. There are relatively much fewer pedestrians
at ground level.
LCA5 – Wan Chai Northwest
7.24
This section of waterfront area is dominated by the
roads and some public to semi-public parks and gardens, such as the HKCEC’s
garden to west of Grand Hyatt Hotel.
There are only occasional pedestrian activities along the roads and the
adjacent public open spaces along the
VSR1 – HKCEC “New Wing”
7.25
The VSR consists of visitors and tourists inside and
around the existing HKCEC “New Wing”.
There are views of
VSR
7.26
The VSR consist of mostly visitors and tourists inside
the existing HKCEC “Old Wing” and the existing Atrium Link, and residents of
the nearby hotels including the Grand Hyatt and Renaissance Harbour View. This VSR in particular has prominent view of
the existing HKCEC “New Wing” and the proposed Atrium Link Extension due to its
orientation towards
VSR1B – Wan Chai Waterfront
7.27
The VSR consists of mostly travelers on foot and on
vehicles on
VSR2 – Wan Chai
7.28
The VSR consists of mainly workers in skyscrapers,
such as the
VSR3 – Central to Admiralty
7.29
The VSR consists of a mix of workers, travelers,
visitors, tourists and military personnel along Central’s waterfront, such as
the IFC Tower, Exchange Square, Star Ferry Pier, Queen’s Pier and the large,
temporary vacant lot to the east of Central Barracks frequently used for
carnivals, shows and concerts. The VSR has many different view angles towards
the Wan Chai waterfront, with occasional glimpse or partial views of HKCEC “New
Wing”. The receiver population is high. Figure
VSR4 –
7.30
The VSR consists of a mix of residents and workers of
high-rises and road-users on elevated bridges near Cross-Harbour Tunnel and
Island East Corridor. It also includes
the visitors, workers and engagers of water recreation at the low-rise Royal
Hong Kong Yacht Club and the Causeway Bay Typhoon Shelter. The VSR generally has the glimpse views of
HKCEC “New Wing”. The receiver population is high. Figure
VSR6 –
7.31
The VSR consists of travelers and tourists on ferries,
cruises, yachts and boats on
VSR8– Tsim Sha Tsui
7.32
The VSR consists of mostly visitors and tourists of
the waterfronts public to semi-public open spaces, recreational facilities,
piers, shopping malls, and hotels, such as Ocean Terminal, Star House, Star
Ferry Pier, Hong Kong Cultural Centre, Hong Kong Space Museum, Hong Kong Museum
of Arts, Avenue of Stars, Intercontinental Hotel, New World Centre, Shangri-La,
Tsim Shan Tsui Centre, Empire, Intercontinental Grand Stanford, Nikko
etc.. It has very prominent view of the
HKCEC northern I and the Promenade, but the rest of HKCEC blocked by its
building mass, resulting in a glimpse view only. The receiver population is
high. Figure
VSR9 – Hung Hom
7.33
The VSR consists of a mix of residents, workers,
visitors and tourists of the high-rises offices and hotels along the waterfront
of Hung Hom, such as the skyscraper Harbourfront Landmark,
VSR10 –
7.34
The VSR consists of mostly residents of skyscrapers,
such as The Harbourside and Victory Arch.
It also consists of the currently large vacant land for the future
comprehensive development in
Landscape Impact Assessment (Before Mitigation)
7.35
Landscape impact arisen from the proposed works will be mostly
on landscape character. In terms of
landscape resources, there will be some existing street trees along
LR1 – Urban Waterfront and Harbour
7.36
The construction will temporarily cover an extensive
area of the waterfront and thus will impose Substantial impact to the LR. Approx.
LR2 –Urban Street/ Amenity Planting
7.37
About 13 nos. and 1 no. group of existing street trees
(comprised of all small, slow-growing Cinnamomum
camphora) along
LR3 – Urban Open Space
7.38
The
proposed works will use an existing open space to the west of HKCEC along the
LCA1 – HKCEC “New Wing”
7.39
The construction will temporarily
disturb the ‘tidy’, commercial and iconic character of the area, inducing a
Moderate impact. During operation, the
Atrium Link Extension will restore its original character, imposing
Insubstantial impact. With Road P2, WDII
etc., the Atrium Link Extension will not impose additional or cumulative
impact.
LCA2 – Sea Channel Space
7.40
The construction will cover almost the entire existing sea channel space, the impact during
construction should Moderate even though the LCA’s sensitive is Low. During operation, the space will be quite
similar to the existing condition.
Although the proposed ALE will intensify and increase the existing shade
areas, the overall impact to the character should be Slight. With Road P2, WDII etc., the Atrium Link
Extension will not impose additional or cumulative impact, and thus the impact
should remain as Slight.
LCA3 – Transport Node
7.41
The proposed will not affect this LCA. The impact should be Insubstantial during
both construction and operation. With
Road P2, WDII etc., the proposed ALE will not impose additional or cumulative
impact.
LCA4 – Wan Chai North Commercial
7.42
The impact
for this LCA during construction will be Moderate for similar reasons to that
of LCA1. During operation, from the
landscape point of view, the bulkiness of the proposed Atrium Link Extension
will moderately affect the commercial character. The construction of Road P2, WDII etc. will
continue to cause the bulkiness of the proposed Atrium Link Extension to impose
Moderate impact.
LCA5 – Wan Chai Northwest
7.43
The construction will temporarily disturb the
‘retreat’ nature of the LCA, imposing Moderate impact. During operation, the impact will become
Insubstantial as the area will be reinstated to the original state. With Road P2, WDII etc., the Atrium Link
Extension will not impose additional or cumulative impact.
7.44
A brief existing tree survey and a joint site visit
with representatives from Leisure and Cultural Services Department (LCSD) have
been carried out in early December 2005.
Existing trees to be affected by the proposed work are surveyed and
identified on a survey plan and on an assessment table with photos in Appendix 7.2. These trees are generally small trees in fair
to poor condition and are of common species.
Some of these trees are found within a roadside public open space
currently maintained by Kiu Lok Service Management Co. Ltd. – a company employed
by HKCEC. Any proposed treatment to
these trees shall be approved by Lands Department under the lease of
HKCEC. The rest of the trees are
considered as “Roadside Trees” or “Street Trees” under the maintenance of
LCSD. All existing trees proposed to be
transplanted shall be directly transplanted to the large existing HKCEC garden
to the west of HKCEC “Old Wing” near Grand Hyatt Hotel. There will be no so-called temporary holding
nursery for the transplanted trees because such practice is inconsiderate to
tree health. Upon completion of the
construction of the proposed Atrium Link Extension, all existing plant-bed and
tree-pit planting will be reinstated with new trees.
7.45
The proposed works will be under a design-build
contract in which an awarded contractor will be responsible for design and
reassessment of existing trees to be affected.
Treatment to existing trees (i.e., Retain, Transplant or Fell) proposed
in this report is based on the best-available architectural and engineering
information. Finalized tree felling/ transplanting
applications and planting proposal shall be submitted for approval to relevant
authorities before commencement of works.
7.46
With or
without the proposed Atrium Link Extension, some of the existing trees are
planted in raised planter with limited width but they are of large tree
species. These trees shall be
removed. After the construction of the
Atrium Link Extension, the planter shall be reinstated and shall be planted
with more suitable trees and palms to avoid possible maintenance problem.
Visual Impact Assessment (Before Mitigation)
VSR1 – HKCEC “New Wing”
7.47
People from both inside and outside the “New Wing”
will have a clear view to the construction, which is very visually incompatible
with the existing surroundings. However,
since its main view is orientated towards the Harbour and Tsim Sha Tsui, the
VSR will only suffer from Moderate (rather than Substantial) impact. During operation, as the proposed Atrium Link
Extension is rather similar to the existing one, the impact will be
Slight. With Road P2, WDII etc., the
proposed Atrium Link Extension will continue to impose Slight impact.
VSR
7.48
As the VSR has its main view orientated towards the
harbour, the construction will greatly affect its visual quality. Construction activities at the interface
between the proposed Atrium Link Extension and “Old Wing” may also disturb
visitors and users of the “Old Wing” even they are inside the building. The construction will thus impose Substantial
impact. During operation, the proposed
Atrium Link Extension will unavoidably block certain view from inside the “Old
Wing” to the harbour (Refer to Photomontage PM2 – Day 1 Without Mitigation on Figure 7.25). The large, flat hardpaved roof also impose
Moderate impact to tourists and visitors inside Renaissance Harbour View Hotel and Grand Hyatt Hotel (Refer to
Photomontage PM3– Day 1 Without Mitigation on Figure 7.26). The completed
Atrium Link Extension will actually block some undesirable view to the construction
of the possible Road P2, WDII etc. This
is somewhat beneficial and thus the ultimate impact should reduce to
Slight. Visual impact for Renaissance
Harbour View Hotel will be assessed in detail in the next section.
VSR1B – Wan Chai Waterfront
7.49
The VSR, which is comprised of mostly travelers on
foot and on vehicles, will have a clear view to the construction, which is very
visually incompatible and will take up an extensive area of the waterfront,
inducing Substantial impact. During
operation, the increased bulk and shade created by the Atrium Link Extension
will impose Moderate impact, especially to receivers along
VSR2 – Wan Chai
7.50
Only office workers in the upper level of the skyscrapers
will have full view to the construction, which will be visually incompatible
with the surroundings. Since these
people at high attitude cannot see the works unless they get close to windows
and look down, the impact during construction should be Slight. As soon as the construction completes, during
operation, the impact will become Insubstantial. With Road P2, WDII etc., the proposed ALE
will not impose additional or cumulative impact.
VSR3 – Central to Admiralty
7.51
Due to its great distance to the works and its
prevailing view across the Harbour to the north, the VSR will only suffer from
Slight to Insubstantial impact during construction and during operation
respectively. With Road P2, WDII etc.,
the proposed ALE will not impose additional or cumulative impact.
VSR4 –
7.52
Only office workers in the upper level of the
skyscrapers will have full view to the construction. Since these people at such a high attitude
cannot see the construction unless they get close to windows and look down, the
impact during construction should be Slight.
As soon as the construction completes, during operation, the impact will
become Insubstantial. With Road P2, WDII
etc., the proposed ALE will not impose additional or cumulative impact.
VSR6 –
7.53
For this VSR, the construction of the proposed Atrium
Link Extension will disturb the ‘background’ of the HKCEC “New Wing” – one of
the icons of
VSR8 – Tsim Sha Tsui
7.54
Although the VSR is of High sensitivity, its view
towards the construction will be mostly blocked by HKCEC New Wing. In addition, with great distance from the
proposed works, the impact should be Insubstantial. With Road P2, WDII etc., the proposed ALE
will not impose additional or cumulative impact.
VSR9 – Hung Hom
7.55
With such great distance and relatively small scale of
the proposed works, the impact should be Insubstantial. With Road P2, WDII etc., the proposed ALE
will not impose additional or cumulative impact.
VSR10 –
7.56
Impact to this VSR
should be similar to that of VSR9.
Detail Visual Analysis for the lower
levels of Renaissance Harbour View Hotel (Part of VSR
7.57
The proposed Atrium Link Extension will extend
substantially on the side facing Renaissance Harbour View Hotel and only
slightly on the side facing Grand Hyatt Hotel.
Possible visual impact imposing to the lower levels of Renaissance
Harbour View Hotel will be much more significant than that to Grand Hyatt
Hotel. Possible unmitigated visual
impact during operation of the Atrium Link Extension to each lower levels of
Renaissance Harbour View Hotel together with existing use is assessed and shown
on Table 7.6. It is found that M/F of Renaissance Harbour
View Hotel will suffer from Substantial impact, and 1/F, 11/F and 12/F will
suffer from Moderate visual impact.
7.58
Impact grading on the last column of the Table is
based on a combination of intuition and qualitative analysis. They aim not to compute or to justify the
overall Impact Significance for VSR

Recommended Landscape and Visual Mitigation Measures
7.59
Recommended
mitigation measures, which are applicable to individual LR, LCA and VSR, are
tabulated in Table 7.7, together with an indication of the responsible
parties for funding, implementation, management and maintenance. Figure 7.21 and Figure 7.22
illustrates the recommended landscape mitigation measures to be implemented for
the area underneath the Atrium Link Extension and for the roofs.
7.60
Mitigation
measures during construction will be implemented from the start and shall be
applied for the whole duration of the construction period. Mitigation measures during operation will be included in the
detailed design and shall be constructed or built up during the
construction. All mitigation measures
will be implemented by TDC’s contractors and hotel operators.
7.61
The
potential residual landscape and visual impacts during construction and during
operation after mitigation are provided in Table 7.8 to Table 7.9.
Scenarios if all possible waterfront
future developments (e.g. Road P2, WDII etc.) are to be constructed are
considered separately for Day 1 operation, Year 10 operation of the Atrium Link
Extension.
7.62
With mitigation measures, only 1 no. LR and 2
nos. VSRs will suffer from Moderate impact:
LR1 – Urban
Waterfront and Harbour
7.63
Mitigation measures will not be able to deal
with the fact the construction will cover a significant area of the waterfront
and the sea. The residual landscape
impact during construction will be Moderate.
VSR
7.64
With
such close distance and prevailing view towards the New
Wing and the Harbour, the hotels will still have much view to the construction
even with mitigation measures. No matter
how much temporary screen is provided, the construction still cannot be
‘hidden’ from the hotels. The residual
visual impact during construction will be Moderate.
VSR1B – Wan
Chai Waterfront
7.65
Even
with mitigation measures, tourists enjoying and taking
photos of the waterfront will still have much view to the construction, which
is visually incompatible. It will be
impossible and unpractical to ‘hide’ the construction in such as an open
area. The residual visual impact during
construction will be Moderate. During
operation and with Road P2, WDII etc.., mitigation measures will not be able to
deal with the significant increase in covered vehicular surface, inducing
Moderate visual impact.
Photomontage of Residual Visual Impact
7.66
Photomontages of Residual Visual
Impact for Day 1 after mitigation are illustrated in Figure 7.24 – Figure 7.27. The locations of the view of the
photomontages are mapped in Figure 7.23. Due
to the urban context and relatively little use of new vegetation as
mitigations, photomontages for Year 10 will NOT be provided in this report.
7.67
Due to
the great uncertainty of the programme and layout of all
adjacent waterfront developments, generic limits of the proposed Road P2 is
shown in dash lines for reference only.
This should not be considered as an assumption that these developments
will or will not be constructed.
Three-dimensional Architectural/ Landscape Illustration
7.68
A
digital model of the proposed ALE has been constructed. It is shown in Figure 7.28 to provide a three-dimensional illustration and a
better understanding of the exterior design, especially for the roofs.
Conclusion
7.69
There
will be some residual impacts due to the construction of the
proposed ALE:
-
LR1
Urban Waterfront and Harbour will receive Moderate residual landscape impact,
-
VSR
-
VSR1B
Wan Chai Waterfront will receive Moderate residual visual impact.
7.70
There
will be only minor residual impact due to the operation of the proposed ALE:
-
VSR1B
Wan Chai Waterfront will receive Moderate residual visual impact if possible
waterfront developments proceed.
7.71
The
proposed Atrium Link Extension will significantly increase the size of the exiting
Atrium Link to meet the need for the expanding exhibition demands in
the region. It will increase the size of
the building structure, rooftop surfaces, and shady areas underneath it. But with cascaded rooftops landscaped with
various in-situ planting and potted planting (30% of the roof area as planting
area for the project will be achieved), suitable architectural façade treatment
and sensitive design for covered shady area underneath, the Atrium Link
Extension will not impose substantial landscape and visual impact. It will reinforce the image of HKCEC as the
choice of exhibitions for regional and global businesses. With reference to criteria defined in Annex
10 of the EIAO TM, landscape and visual impacts in the construction and
operational phases will be acceptable
after applying mitigation measures.

Visual
Screen – Construction
activities will be very incompatible with the existing surroundings. It will substantially affect the visual
quality and landscape character of area.
It is necessary to develop mitigation measures to reduce the visual
impact. Hoarding Design – The
hoardings shall serve as visual screen for the construction. They shall be sufficient tall and properly
designed to reduce the visual impact to the surroundings. They shall also be well-maintained and
cleaned frequently throughout the construction period. Temporary Partition Walls - The proposed
Atrium Link Extension will involve much interface works to the hotels, HKCEC
“New Wing” and “Old Wing”. Partition
walls shall be properly designed and installed inside the buildings around
interface areas to be closed off for construction. Screen for Hotels – The
hotel will have a direct view to the construction site. TDC shall liaise with
the hotel operators to take appropriate measures to reduce the impact, e.g.
the use of curtains or provisions of temporary screens, if necessary. |

Temporary
Footbridge – The existing Atrium

Existing
Trees within Works Areas – The project engineer has designated several
works areas near the construction for possible site offices and material
storage, including an existing public waterfront open space to the west of
HKCEC (designated by the engineer as Works Area E). The land use for these works areas should be
flexible so that no tree felling or transplanting will be required. All existing trees within these works areas
shall be properly maintained and protected for their crowns, trunks and
roots. Should the boundary of
construction expand during the construction, the scope of tree protection shall
also expand respectively. Once the construction
completes, the open space shall be reinstated to match the existing and
reopened to the public. |

Design for Rooftop Spaces – The existing Atrium Link roof is extensively
hardpaved with some exposed architectural/ structural metal features. The proposed Atrium Link Extension will
create a larger flat roof, but there is great opportunity for
improvement. TDC intends to utilize
the roof at +51.80 as gardens and the roof at +55.80 for placement of
satellite dishes and for private functions.
The followings should be considered: - Soft Landscape – The
existing and the proposed Atrium Link Extension will span over an existing
sea channel of substantial width of over 80 metres to cater for future
possible Roof Finish – The roofs
shall be finished with paving materials in several colour tone variations,
such as different shades of greens, to visually break down the ‘bulkiness’ of
vast flat roof. The roof at +41.15 is
considered as architectural ‘wing’ roof supporting the overall modern to
contemporary style of HKCEC. It will
be accessible only to maintenance crews and will be paved with non-reflective
materials with various tones of colours and textures to form paving patterns
that are readable from a distance. Lighting – The proposed
rooftop garden at +51.80 and the upper roof deck at +55.80 shall generally
adopt a ‘landscape’ approach to avoid unnecessary glare. It is
expected that the upper roof deck at +55.80 will be used for passive
functions, such as wine tasting.
Active functions, such as games shows, will not take place there. Figure 7.22 shows
the landscaped rooftops of the proposed Atrium Link Extension. Figure 7.28 provides a three-dimensional
illustration of the rooftop spaces. Figure
7.30 provides photo illustration for the landscape design. Figures 7.31 & 7.32 show
sections across the proposed building structure and outdoor areas. |

Sensitive
Design for Shady Area – The existing public
area under the existing Atrium Link is only used by a few pedestrians during
the day. While the proposed Atrium
Link Extension will intensify the shade, there are great opportunities to
improve the space. A number of
sensitive designs shall be provided for this covered but open-air public
space: - Paving – The area shall
be hardpaved with paving materials with various colour and textures to form
paving patterns that enhance the visual quality of the space. Hard Landscape - Simple
hard landscape design such as rockworks, may create some interests/ focus to the
space. Decoration to the bottom of the
ALE, together with other decoration to the ALE, may also be provided during
festivals to improve the appearance of the space. Soft Landscape - Planter
beds with small palms (such as Chrysalidocarpus
lutescens) similar to the existing
ones shall be provided at the edge of the cover to increase overall amenity
value and to ‘hide’ the staircases and fire exits from the Atrium Link
Extension above. Lighting – The space
shall be sufficiently lit by ceiling mount lights day and night via an
intelligent system of photocells, timers, and manual bypass. Luminance level shall be designed to
achieve the standards required by Highway Department’s Public Lighting Design
Manual. Tentatively, the section for
“Covered Public Transport Interchanges” in the Manual may be referenced for
the consideration, subject to further liaison with Highway Department and
Transport Department. Electrical
wiring shall be designed to turn on or off lights in interpolated groups so
that the overall luminance can be adjusted during different time of a day. Figure 7.21 shows
the landscaped treatment to the space under the proposed Atrium Link
Extension. Figure 7.29 provides
photo illustration for the landscape design. Figure 7.32 shows section across the
proposed building structure, outdoor and shady areas. |

Design for Building Architecture – Smaller exhibition halls should be placed at
the upper levels of the proposed Atrium Link Extension to create cascades to
visually reduce the bulkiness of the building structure and to create
rooftops for greening opportunities. The
design of the east and west elevation of the proposed Atrium Link Extension shall
merge into the existing architectural language of the HKCEC “New Wing”
articulated with linear lines and varying degree of opacity to visually break
down the scale of the facades. Colours
and materials to be used should ensure an overall harmonious image of the
entire HKCEC development. Various photomontages in Figures
7.24 – 7.27 demonstrate the façade treatments. Figure 7.28
provides a three-dimensional illustration of the cascaded building forms of
the proposed Atrium Link Extension incorporated with landscaped rooftops. |
