·
Identification
of the baseline landscape resources (LRs) and landscape characters found within
the study area. This is achieved by site visits and desktop
study of topographical maps, information databases and photographs.
·
Assessment
of the degree of sensitivity of the LRs and landscape character areas (LCAs). This is achieved by desktop study of
Landscape Value Mapping of Hong Kong and other relevant information. This is
influenced by a number of factors including:
o
whether
the LRs/ LCAs are considered to be of local, regional, national or global
importance;
o
whether
there are any statutory or regulatory limitations/requirements relating to the
LRs/ LCAs;
o
quality
and maturity of the LRs/ LCAs;
o
rarity of the LRs/ LCAs; and
o
ability
of the LRs/ LCAs to accommodate change.
·
The
sensitivity of each LR and LCA is classified as follows:
High: |
Important
landscape character or landscape resource of particularly distinctive character
or high importance, sensitive to relatively small change. |
Medium: |
Landscape
character or landscape resource of moderately valued landscape
characteristics reasonably tolerant to change. |
Low: |
Landscape
character or landscape resource, the nature of which is largely tolerant to
change. |
·
Identification
of potential sources of landscape changes.
These are the various elements of the construction works and operation
procedures that would generate landscape impacts.
·
Identification
of the magnitude of landscape change.
The magnitude of the change depends on a number of factors including the
physical extent of the change, the compatibility of the Project with the
surrounding landscape, the duration of impact and the reversibility of change. Landscape changes have been quantified
wherever possible. The magnitude of
landscape changes is classified as follows:
Large: |
The
landscape character or landscape resource would involve a major change. |
Intermediate: |
The
landscape character or landscape resource would involve a moderate change. |
Small: |
The
landscape or landscape resource would involve slight or barely perceptible
change. |
Negligible: |
The
landscape or landscape resource would involve no discernible change. |
·
Identification
of potential landscape mitigation and enhancement measures. These may take the form of:
o
adopting
alternative designs or revisions to the basic engineering and landscaping
design to prevent and/or minimise adverse impacts before adopting other
mitigation or compensatory measures to alleviate the impacts;
o
potential
mitigation measures include preservation of vegetation and natural landscape
resources, transplanting trees with value and in good condition, colour and
textual treatments to structures (e.g. the promenade and breakwater); and
o
potential
compensatory measures include the implementation of landscape design and
beautification works (e.g. provision of amenity planting, screen planting,
reinstatement of disturbed lands, aesthetic design of aboveground/above-sea-level
structures/hardscape features such as using finishes, colour scheme, texture of
materials) to generate potentially beneficial long term impacts.
A programme for the
mitigation measures is provided and discussed in Section 11.8.
The agencies responsible for the funding, implementation, management and
maintenance of the mitigation measures are proposed in Table 11.10
and Table 11.11.
·
Assessment
of the significance of landscape impacts before and after the implementation of
the mitigation measures and enhancement measures. By synthesizing 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 11.1
shows the rationale for dividing the degree of significance into four
thresholds, namely insubstantial, slight, moderate, and substantial, depending
on the combination of a negligible-small-intermediate-large magnitude of change
and a low-medium-high degree of sensitivity of LRs/ LCAs.

The
significance thresholds are defined as follows:

or improvement in existing landscape quality. |
Moderate: |
Adverse
/ beneficial impact where the proposal would cause a noticeable deterioration
or improvement in existing landscape quality. |
Slight: |
Adverse
/ beneficial impact where the proposal would cause a barely perceptible
deterioration or improvement in existing landscape quality. |
Insubstantial: |
No
discernible change in the existing landscape quality. |
·
Assessment
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.
·
Identification
of the Visual Envelope during the construction and operation phases of the
Project. This is achieved by site visit and desktop
study of topographic maps, photographs and preparation of cross-sections to
determine visibility of the Project from various locations.
·
Identification
of the VSRs within the Visual Envelope at construction and operation phases. These are the people who would reside, work,
or take leisure within, or travel through, the Visual Envelope.
·
Assessment
of the degree of sensitivity to change of the VSRs. Factors considered include:
o
The
type of VSRs, classified according to whether the person is at home, at work,
at play, or travelling. Those who view
the change 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 also display varying
sensitivity depending on the speed of travel; and
o
other
factors considered (as required by EIAO GN 8/2010) include the value and
quality of existing views, the availability and amenity of alternative views,
the duration or frequency of view, and the degree of visibility.
·
The
sensitivity of VSRs is classified as follows:
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. |
·
Identification
of relative numbers of VSRs. This is
expressed in terms of whether there are “many“, “medium” or “few” VSRs in any
one category of VSR.
·
Identification
of potential sources of visual changes.
These are the various elements of the construction works and operation
that would generate visual changes.
·
Assessment
of the potential magnitude of visual changes. Factors considered include:
o
the
compatibility with the surrounding landscape;
o
the
duration of the impact;
o
the
reversibility of the impact;
o
the
scale of the impact and distance of the source of impact from the viewer; and
o
the
degree of visibility of the impact, and the degree of which the impact
dominates the field of vision of the viewer.
·
The
magnitude of visual changes is classified as follows:
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. |
·
Identification
of potential visual mitigation and enhancement measures. These may take the form of:
o
adopting
alternative designs or revisions to the basic engineering design and landscape
design to prevent and/or minimise adverse visual impacts before adopting other
mitigation or compensatory measures to alleviate the impacts;
o
potential
mitigation measures include preservation of vegetation and natural landscape
resources, colour and textual/ finishing treatment of structures (e.g. the
promenade and breakwater); and
o
potential
compensatory measures include the implementation of landscape design and
beautification works (e.g. tree/ shrubs planting, aesthetic design of
aboveground/above-sea-level structures/hardscape features such as using
finishes, colour scheme, texture of materials, and creation of new open space,
etc) to generate potentially beneficial long term impacts.
A programme for the mitigation
measures is provided and discussed in
Section 11.8. The agencies responsible for the
funding, implementation, management and maintenance of the mitigation measures
are proposed in Table 11.10.
·
Assessment
of the significance of visual impacts before and after the implementation of
the mitigation and enhancement measures.
By synthesizing 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 11.2
shows the rationale for dividing the degree of significance into four
thresholds, namely, insubstantial, slight, moderate and substantial, depending
on the combination of a negligible-small-intermediate-large magnitude of change
and a low-medium-high degree of sensitivity of VSRs.

Open Space (O) |
3371 m2 |
The current design is in line with the
primary intention of the approved OZP that outdoor open-air public space will
be provided for active and/or passive recreational uses serving the needs of
local residents as well as the general public. |
Under the Project, the Lei Yue Mun
waterfront including the existing viewing platform, lookout points and
footpath will be revitalised with the provision of greening, improved paving
scheme, a children’s play area, viewing platforms, sitting-out areas and
improved waterfront promenade, which provide a harmonious and relaxing open
space as well as an unwinding arrival experience at the proposed public
landing facility. The quality of the area is expected to be improved from
both the landscape and visual perspectives. With the provision of a cosy and
neat public landing facility and waterfront promenade sited strategically at
a convenient location, the regional significance of the place will also be
augmented. While the concerned area will accommodate majority of the proposed
enhancement works, the scale of the mentioned works is considered small and
compatible with the surrounding environment. This kind of land use is fairly
common found in Hong Kong. |
Other Specified Uses (OU)
annotated “breakwater” |
174 m2 |
The current design is in line with
the primary intention of the approved OZP that land will be provided for
breakwater. |
Following
the approved OZP, this is a trivial protrusion from the coastline that will
visually blend well into the existing surrounding coarse texture of the rocky
shore and Oyster Shell Beach. While the original quality of inshore waters in
the concerned area will be changed, the proposed small-scale breakwater will
cause limited and negligible impact to the concerned area due to its
landscape and visual compatibility with the surrounding proposals and
existing conditions. The significance
of change in the local and regional context is considered negligible. This
type of land use is fairly common in Hong Kong. |
|
Village Type
Development (V) |
2300 m2 |
The current
design is in line with the primary intention of the approved OZP that land
will be provided for the retention and expansion of existing villages, and
land will be reserved for the re-provision of village houses affected by
Government projects. |
This area is mainly composed of low-rise
village houses and restaurants. In between buildings are in general linear
open spaces, e.g. streets, and nodes of gathering points, e.g. lookout
points, In the vision of creating a better
environment for passive uses, the Project mainly involves re-pavement along
streets and provision of furniture, greening and other landscape elements in
several lookout points. The scale of the proposed enhancement works of the
concerned area is small and its significance to the local and regional
context is slight. In general, the quality of the spaces in this area will be
enhanced when the proposed works has been carried out. |
|
Coastal Protection Area (CPA) |
0 m2 |
The current design is in line with
the primary intention of the approved OZP that the lighthouse, the natural
coastlines and the sensitive coastal natural environment, including scenic
value, will be conserved, protected and retained. |
No
works will be carried out within the CPA. However, considering the proposed
dredging works are in the vicinity of the CPA, mitigation measures during
construction and operation phases (e.g. capital and maintenance dredging
respectively) are proposed which include a buffer zone between the CPA and
the proposed dredging area with the shortest distance of about 10m and
deployment silt curtains to prevent dispersion of suspended sediments during
dredging works (details are presented in Section
5.8). |
Table 11.4 Baseline
LRs and their Sensitivity
LRs |
Description |
Sensitivity |
LR 1 |
Recreation
Ground This landscape resource represents sites
locating in an urban/semi-urban context that accommodate open spaces for both
active activities, e.g. football pitches, basketball courts and fitness
equipment, and passive activities, e.g. resting and informal games. The
extent of topographic changes vary in different sites, but the open spaces
within which are in general levelled to facilitate active and passive
activities. This type of landscape resource is mostly lushly planted with
great varieties of trees and other plant species, so this type of landscape
resource is also an urban habitat for wildlife. In this LVIA, the type of
Recreation Ground includes Sam Ka Tsuen Recreation Ground and Lei Yue Mun
Rest Garden to the northeast of the Lei Yue Mun Lighthouse. Although this
landscape resource is quite well established and of high quality, LR 1 is
commonly found in Hong Kong. It provides open spaces for active and passive
uses in the local district, so LR 1 is an important landscape resource and LR
1’s ability to accommodate changes is considered moderate. |
Medium |
LR 2 |
Seafront Promenade & Pier Seafront
Promenade and Piers consist of a linear open space that wrap around Sam Ka
Tsuen Typhoon Shelter serving mainly passive activities, such as jogging,
rambling and resting. Planting in this type of LR is generally simple in
forms and geometry, so as to provide a strong legibility of the space. Street
trees, such as Delonix regia and Hibiscus tiliaceus are deployed to
reinforce the visual rhythm. LR 2 is a common, well-established, high quality
landscape resource frequently used by local residents and tourists for
passive uses. Therefore, it is an important landscape resource and its
capacity to accommodate changes is considered low. |
High |
LR 3 |
Industrial
Development This type of LR is composed of a range
of factories, and car parks. Some of the land parcels were quite open which
were occasionally and partially covered by ruderal vegetation. Yet, there was
not an obvious planned greenery network within this type of LR. In principle,
the factories were mid-rise buildings with the high-rise residential estate
to its eastern side as background. As
these factories have a great demand for logistics, roads within this type of
LR are usually frequently used by trucks, making the landscape resource not
very suitable for leisure activities. LR 3 is a very common and not very well
established landscape resource. Only a small amount of workers frequently
visit LR 3 and the time they stay in LR 3 is short on a daily basis, so it is
an unimportant landscape resource in the local and regional context. The
quality of LR 3 is low. Therefore, LR 3 can tolerate huge changes. According
to the approved Cha Kwo Ling, Yau Tong, Lei Yue Mun Outline Zoning Plan No.
S/K15/25 (April 2017), the majority of LR 3 is currently planned to be
Comprehensive Development Area (CDA) and Residential (Group E). |
Low |
LR 4 |
Coastal Village This type of LR stretching along to the north of Lei Yue Mun
coastline is occupied mainly by small village houses, shops and restaurants.
Paths within this type of LR are relatively narrow that discourages motorised
vehicular traffic. However, the overall setting promotes people lingering
across it. Patches of plants that are mostly of ornamental species are
provided by the local residents, shop owners and institutions can be found in
this type of LR. A potentially registrable Old and Valuable Tree (pOVT) is
also identified to the eastern side of Lei Yue Mun Rest Garden and in the
open space in front of Monet Garden. The tree is a Ficus microcarpa with a wide and balanced canopy and the local
residents believe that it brings fortune according to the script on a plaque
erected in front of the tree. The quality of LR 4 was fair and people
could quite often encounter this landscape resource. However, it was a quite
well established landscape resource and also important in the local and
regional context as it defined Lei Yue Mun’s identity and sense of place. LR
4 was considered to have moderate capacity to accommodate changes. |
Medium |
LR 5 |
Residential
Development This type of LR located on the northern
side of the study boundary is predominantly comprised of high-rise
residential estates divided by roads. Roadside tree planting, such as Hibiscus tiliaceus and Melaleuca cajuputi subsp. cumingiana, are also found. LR 5 is of
a fair quality and well established. Since this type of LR can commonly be
found in Hong Kong, it has lower importance in the local and regional
context. However, as residents stay a
long time in LR 5 every day and are familiar with this LR. Thus, its capacity
to accommodate changes is considered moderate. |
Medium |
LR 6 |
Historic Site This type of LR includes
sites that contain historic buildings and structures. Within the study
boundary, a Tin Hau Temple and fortifications are identified to the south of
Ma Pui Tsuen and on the hillside of Devil’s Peak facing Lei Yue Mun,
respectively. Both localities are relatively open in the core of the sites
while trees and other vegetation grow on the peripheries. Tin Hau Temple and
Fortifications at Devil’s Peak are graded 3 and 2, respectively by
Antiquities Advisory Board. As Tin Hau Temple located at a semi-urban area,
it is believed that more people, especially followers of Tin Hau would visit
the site whereas fortifications would be visited mainly by hikers. The
quality of LR 6 was fair. LR 6’s historical grading results in its high
importance in the local and regional context, higher rarity and high
maturity, but lower capacity to accommodate changes. |
High |
LR 7 |
Rocky Shore and Oyster Shell Beach This type of LR is located to the west
of Lei Yue Mun Rest Garden and is very open and mildly flat with a coarse texture
at ground. The lighthouse at the tip of the Oyster Shell Beach is a landscape
feature of the landscape resource. Due to the presence of the lighthouse and
the openness of the area allowing a vista of the Hong Kong Island side, the
site is frequently visited by local residents and tourists. As indicated in
OZP No. S/K15/25, this LR falls within the Coastal Protection Area (CPA).
This LR is intended to be conserved and protected with the retention of the
lighthouse, the natural coastal and the sensitive coastal natural
environment, including area of scenic value. There should be minimum built
development. LR 7 is of high quality, well-established and was relatively
uncommon. The process of public engagement also reveals that the local
villagers treasure LR 7 tremendously and expressed huge desire to preserve LR
7. Thus, LR 7 is an important landscape resource. Together with the
consideration of the planning intention concerning LR 7, its capacity to
accommodate changes is low. |
High |
LR 8 |
Semi-natural Woodland
Sites of semi-natural woodland are
disturbed areas with a certain degree of colonization of native vegetation,
e.g. Macaranga tanarius var. tomentosa. However, invasive weedy Leucaena leucocephala and other
non-native species are also spotted. Since
this landscape resource is not intended to be visited by general public, it
is usually not actively maintained. However, this type of LR can be a habitat
for wildlife and part of green infrastructure within the district. LR 8 is of
fair quality and is quite mature, yet this type of LR can be commonly
encountered and unimportant in the local and regional context. Hence, LR 8’s
capacity to accommodate change is considered high. |
Low |
LR 9 |
Semi-natural Uphill Woodland & Other
Vegetation The landscape resource is located within
rural areas with greater topographic changes and is composed of more native
species, such as Litsea glutinosa, Litsea rotundifolia, Mallotus paniculatus, Rhus succedanea and Sapium discolor. On the other hand,
non-native pioneering species are also encountered, such as Acacia confusa, Acacia mangium and Lophostemon
confertus. Hiking trails are available for hikers to stroll around the
landscape resource. LR 9 is of good quality
and well established, but it is a common type of LR in Hong Kong. As it
provides trails and open spaces for hiking and other passive uses, this LR is
moderately important in the local and regional context. Its capacity to
accommodate changes is considered moderate. |
Medium |
LR 10 |
Bay Area This
landscape resource comprises water bodies that are close to the Old Lei Yue
Mun Quarry coastline. The quality of LR 10 is high but it can commonly be
found in Hong Kong. It is also very well established and important in the
local context. Thus, its capacity to accommodate changes is considered
moderate. |
Medium |
LR 11 |
Inshore Waters The landscape resource comprises mainly
an open water body in between the Kowloon side and Hong Kong Island side.
Ferries and other vessels often travel across this type of LR, forming part
of the landscape of the place. LR 11 is of high quality and a common
landscape resource. It is well established and important in the local context.
Thus, It is considered with a moderate capacity to accommodate changes. |
Medium |
LR 12 |
Typhoon Shelter The
landscape resource comprises water bodies which most of the time is parked with
vessels. As the water bodies are protected by its surroundings, it was
relatively static. LR 12 was a space of high quality and can be commonly
encountered in Hong Kong. It is well established and important in the local
context. Thus, its capacity to accommodate changes is considered moderate. |

Within the project boundary, Lei Yue Mun
Rest Garden and its vicinity will be revitalised with enhanced paving and
amenity planting. A children’s play
area and sitting-out areas will be provided. Furniture, such as benches and
lighting echoing the overall landscape theme will also be installed at
appropriate locations. Based on the
conceptual design and latest available information, no existing trees will be
felled due to the proposed works. One pOVT has been identified near the Lei
Yue Mun Rest Garden but out the project boundary will be preserved during
construction and operation of the Project. The shoreline of LR 1 comprise of
semi-natural sandy and rocky shore. The construction of the proposed
waterfront promenade with public landing facility will possibly cause
approximately 100m of semi-disturbed natural coastline into artificial
structure. Taking into account the
proposed minor restoration of seawall works by others, approx. 2836 m2
(~80%) of this LR will be affected. In view of the above, it is considered
that the unmitigated impact on LR 1 will be intermediate. Hoardings will be erected on the
periphery of construction sites and access to partial area of the LR will be
restricted during construction. |

Within the project boundary, the
streetscape improvement works (e.g. improved paving) will be carried out
along the existing footpath. Existing lookout points will be revitalised with
the improvement of paving, provision of furniture and amenity planting. Based on the conceptual design and latest
available information, no existing trees will be felled due to the proposed
works. Taking into account the minor
seawall repair works by others under separate project, approx. 2846 m2
(~2%) of the LR will be affected. Thus, the unmitigated impacts caused by the
proposed enhancement works, are considered small. Hoardings
will be erected on the periphery of construction sites and access to partial
area of the LR will be restricted during the construction phase. |

during the construction and operation phases (i.e. maintenance dredging) can
be mitigated with implementation of appropriate mitigation measures. ·
A proposed
carp-shaped platform (~98m2) will be built outside the CPA · An
existing viewing platform outside the CPA will be improved |
The dredging works during the
construction and operation phases will be carried out in the vicinity of the
CPA and may have potential impact to the integrity of the CPA. The potential impacts on the CPA during
dredging works can be mitigated by deploying appropriate mitigation measures
which include establishment of a buffer zone, deployment of silt curtains and
close supervision of the works. A carp-shaped platform will be
constructed outside the CPA which may cause a small area (~98m2)
of the semi-disturbed natural rocky shore into artificial structure. The impact is considered as small. The improvement works to the existing
viewing platform which comprise modification to the existing artificial
seawall and beautification works (e.g. re-paving and amenity planting). Hence, the impact due to this improvement
works is considered as insignificant. Based on the conceptual design and
latest available information, no existing trees will be felled due to the
proposed works. In all, approx. 400 m2
(~24%) of the LR will be affected by the construction of carp-shaped platform
and beautification works at the viewing platform. Since no works will be carried out
within the CPA, the whole CPA, including the lighthouse within it, will be
conserved without any disturbance from the proposed works. It is anticipated
that unmitigated impact on LR 7 during the operation phase will be small. Hoardings will be erected on the periphery
of construction sites and access to partial area of the LR will be restricted
during construction phase. |

Most of the Project Area falls within
LCA 2, yet only 6216 m2 (~1.40%) of the LCA will be affected. Within the project boundary, the
streetscape improvement works (e.g. improved paving) will be carried out
along the existing footpath. Existing lookout points and viewing platform will
be revitalised with the improvement of paving, and provision of furniture and
amenity planting. Lei Yue Mun Rest Garden and its vicinity
will be revitalised with enhanced paving and amenity planting. A children’s play area and sitting-out
areas will be provided. Furniture, such as benches and lighting echoing the
overall landscape theme will also be installed at appropriate locations. Based on the conceptual design and
latest available information, no existing trees will be felled due to the

public landing facility and the carp-shaped platform will possibly disturb a
small area of the semi-disturbed natural sandy and rocky coastline and turn
them into artificial structure. The potential negligible impact posed by
the dredging works during the construction and operation phases to the CPA
can be mitigated by deploying appropriate mitigation measures which include
establishment of a buffer zone, deployment of silt curtains and close
supervision of the works. Taking into account the minor seawall restoration
works by others, it is considered that the works will pose small unmitigated
impact on LCA2 during operation phase. Hoardings will be erected on the periphery
of construction sites and access to parts of the LCA will be restricted
during construction phase. |

|
The water quality of LCA 5 is
expected to receive localised impact during dredging and construction works.
However, this impact is considered as transient in nature. The magnitude of change is considered
negligible. During operation,
maintenance dredging would be required at an interval of about every 5 to 10
years. The magnitude of impact would
be same as the capital dredging. A proposed permanent small-sized
protrusion of breakwater from the existing coastline will be built, so as to
create calmer conditions for berthing of vessels at the public landing
facility during the operation phase. This will result in 175 m2
(0.04%) of the LCA being affected. While the character of LCA 5 should
remain the same, it is anticipated that the unmitigated impact on LCA 5 will
be negligible. |

Viewpoint
VP-1 located at the seafront to the west of Lei Yue Mun Tin Hau Temple and Ma
Pui Tsuen is an at-grade view approximately 0.25km away from the major works of
the proposed public landing facility, representing the view of VSR R-01 who are
the local residents and villagers. This viewpoint is selected because of its
shared popularity among this group of people. The revamped Lookout Points 4
& 5 with better visual quality and part of the breakwater that stands only
a few metres above sea level will be slightly visible from this angle. Apart
from the proposed enhancement works, the proposed works to restore the seawall
after Typhoon Hato which includes the construction of concrete parapet wall and
raising the existing rock armour seawall adjacent to sections of the seafront
footpaths will also be barely noticeable. Altogether, the proposed enhancement
works will be compatible with its existing surroundings and will bring an
overall slightly beneficial visual impact after mitigation to VSR R-01.
·
Viewpoint
VP-2 is located at about 0.63km to the south of the proposed works, which is in
an outdoor space adjacent to the Exhibition Gallery of Hong Kong Museum of
Coastal Defence, and looks towards the southern side of major proposed works
from a higher altitude. VP-2 represents the view of VSR V-01, namely the
visitors to the Museum. It is predicted that trees of mature size can be seen
from that angle but the pavilion will be screened by the trees, and therefore
be barely visible. The proposed enhanced works will therefore be visually
compatible with its existing surroundings and they will have slightly
beneficial visual impacts after mitigation on VSR V-01.
·
Viewpoint
VP-3 is located at the Heng Fa Chuen Promenade on Hong Kong Island facing the
southeastern side of the proposed public landing facility. It provides an
at-grade view approximately 1 km away from the main proposed works,
representing the view of VSR R-02, namely the residents of Heng Fa Chuen. It is
anticipated that fully established trees can be seen from that angle but the
pavilion will again be screened by the trees, and therefore be barely visible.
All in all, the proposed work will be highly compatible with the existing
surroundings visually and they will bring slightly beneficial visual impacts after
mitigation to VSR R-02.
