5.9 The assessment of landscape impacts has adopted the following approaches:
§
Identification of the baseline
Landscape Resources (LR) and Landscape Character Area (LCA) found within the
§ Assessment of “Sensitivity to Change” to the LR and LCA. The assessment would be 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. Ratings are 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. The assessment would be 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 was considered separately for construction phase and operation phase. Ratings are 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 landscape impacts during construction and operation was assessed by synthesizing the “Sensitivity to Change” and “Magnitude of Change” for various LR and LCA according to Table 5.1. The degree of significance would be 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”. Measures were identified for both construction phase and operational phase to mitigate unavoidable adverse impacts and / or generate beneficial long-term impacts. A table for the mitigation measures is provided. Relevant departments responsible for the funding/ implementation and management/ maintenance of the mitigation measures were also identified.
§ Identification of “Residual Impact Significance Threshold after Mitigation” for landscape impacts. This part would refer to the cumulative impacts to LR and LCA after applying mitigation measures, with an assumption that all proposed measures and guidelines would be fully implemented. Similar to the “Impact Significance before Mitigation”, the rating is separately considered for the construction phase and operation phase.
5.10 The assessment of visual impacts has adopted the following processes:
§ Identification of Zones of Visual Influence (ZVI) and Visually Sensitive Receivers Groups (VSRs) during construction and operation. A ZVI has been established by a desktop study of topographic maps, street maps, photographs and site visits to determine the possible VSRs at different locations.
§ Assessment of the “Sensitivity to change” of the VSRs. Factors include:
§ The type of VSRs, such as viewers who are residents, workers, road travellers or recreation engagers. Those people viewing from home are considered to be highly sensitive because the view directly affects their general quality of daily life. 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 the nature of the workplace, i.e. whether it is industrial, retail or commercial in nature. Those people who take part in outdoor leisure activity may have different sensitivity depending on the type of recreation. Those people who are travelling on roads or streets will also have different 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 views, and the degree of visibility.
§ Rating for “Sensitivity to change” of the VSRs is classified as below:
§ High: The VSR is highly sensitive to any changes in their viewing experience.
§ Medium: The VSR is moderately sensitive to any changes in their viewing experience.
§ Low: The VSR is only slightly sensitive to any changes 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.
§ The magnitude of visual impacts during different stages of construction and during operation are separately considered, with ratings 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 the landscape impact assessment, it aims to synthesize the “Sensitivity to Change” and “Magnitude of Change” for various VSRs according to Table 5.1 to assess the visual impacts in a matrix. The degree of significance is divided into four thresholds:
§
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. It is divided into construction phase and operation phase, with proposed 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. Similar to the “Impact Significance before Mitigation”, the rating is divided into the construction phase and operation phase.
§ Preparation of Photomontage. To illustrate and compare the visual impact of proposed works with and without mitigation, computer-simulated views (i.e., photomontages) from selected VSRs are generated. Photomontages after mitigation at Day 1 and at Year 10 are produced.

LCA5
– Inshore Water Landscape
5.66 This LCA is costal water lying close to the shore and enclosed to a certain degree by landmasses, which create a limited sense of enclosure or containment. Whilst the landscape is characterised predominantly by the horizontality and muted hues or the coastal waters, it may also include marine activities of all kinds, including commercial shipping lanes and ferry traffic etc. The result is a largely open and vibrant landscape which is punctuated by the colours and noises of human features and activities. The sensitivity to change is Medium.
LCA7.1 – Industrial Urban Landscape (
5.67
This LCA is found on low-lying
areas of reclaimed land along the coast of
University Station
LCA1.2 – City Grid Mixed Urban Landscape (University)
5.68 This LCA refers to the older reclamation area at western district and is the most extensive urban landscape. It consists of mainly retail land uses at street level with high / medium-rise commercial or residential development above. Streets are often fairly wide and busy with traffic and the large numbers of people using these areas means that street life is vibrant. Building blocks are of mixed age and character, and vegetation is generally limited to street tree planting and shrub planting in occasional public open spaces. The result is a landscape which is vibrant, colourful and diversity in terms of its street life and land use, but which possesses only limited variety in terms of its urban spaces. The sensitivity to change is medium
LCA2.2 – Mix-use Urban Fringe Landscape (University)
5.69 This LCA is found on the periphery of the major urban areas, as a residual landscape type characteristic of the transition of landscapes to a less urban setting. Typically on hillside or seaside around urban areas that are less easily developed, it includes roads, highways structures, slope works, hillsides (often stabilised, otherwise vegetated), scattered residential development, open space, G/IC development (such as service reservoirs, schools etc.). This is transitional landscape which is characterised by the relatively low density, diverse range of features, significant vegetation cover and incoherent structure with features having little formal relationship to each other. The sensitivity to change is Medium.
LCA3.2 – Open Institutional Landscape (University)
5.70 This LCA refers to the urban fringes, characterised predominantly by the institutional land uses such as HKU campus and school buildings. Though covering a variety of different types of institution, the combination of features and components and their distribution in these landscapes tends to be very similar. It comprise extensive complexes of campus buildings (usually low to medium rise) separated by open areas used for circulation or parking, with a high coverage of semi-formal landscape and vegetation. The whole landscape will typically be surrounded by a perimeter fence. This results in landscapes which are extensive, reasonably open and semi-formal. The sensitivity to change is High.
LCA6.2 – Residential Urban Fringe Landscape (University)
5.71 This LCA refers to the area of the residential buildings – The Belcher Garden, which lie at the edges of urban areas and on peripheral hillsides. The landscape comprises intermittent, residential towers on steep hillsides, with winding roads interspersed by wooded hillsides. Buildings relate predominantly to the adjoining roads. The result is a fairly coherent residential landscape with a higher coverage of vegetation, which possesses a relatively informal and tranquil character. The sensitivity to change is Medium.

§ off-site construction traffic such as haulage of excavated materials
§ temporary traffic / road diversions
§ night time lighting
§ temporary noise mitigation measures e.g. barriers, enclosures
§ contractor’s temporary works areas, including site accommodation and parking areas
§ above ground conveyor and barging facilities
5.118 During the operation stage, potential landscape and visual Impacts would be related to the following visible above ground structures :
§ entrances and associated facilities
§ vent shafts for railway tunnel and sub-way
§ chiller plants
§ any noise control structures
§ residual impacts from loss of trees during the construction stage
5.119
Locations of the above features
are shown in Figure
5.120 Based on the above descriptions of landscape resources, and sources of impacts, key landscape issues and potential significant impacts associated with the WIL are presented below. Potential impacts on cultural heritage sites are separately discussed in Table 6.1.
Nature and Magnitude of Landscape Change before
Mitigation in Construction Phase
5.121 The magnitude of the impacts, before implementation of mitigation measures, on the landscape resources and landscape character areas that would occur in the construction phase are described and tabulated in Table 5.2. Only those resources and character areas which will have impact are listed. All impacts are adverse unless otherwise stated.
LR1.1 –
5.122
The temporary works area that
will temporarily alienate part of the playground is required for the cut–and-cover
construction of the underground Kennedy Town Station and the MTRC Entrance. There would be impact on approximately 47
trees. There are 11 no. Roystonea regia
have high amenity value. The required works
area for KET is approx.
LR2.1 – Roadside
planting along Victoria Road in Mount Davis
5.123
There would be direct impact and
approximately 100 trees would need to be felled at the magazine site due to construction
of the underground magazine and access road. Affected species are common including
Macaranga tanarius, Ficus microcarpa and Aleurites moluccana. The required area for the magazine site is
approximately
LR2.2 – Roadside planting
at
5.124
There would be impact on
approximately 15 trees along
LR2.3 – Trees within
Abattoir Site
5.125 Approximately 10 trees located within the Abattoir Site will be affected by the Works area, namely, rock crushing facility, stockpile area, contractor’s site facilities and MTRC and Contractors’ site office. Affected trees would be transplanted where possible and practicable.
LR4.1 – Manmade Slope along Pokfield Path
5.126 Approximately 7 trees located at the cut slope along Pokfield Path will be affected due to the construction of chiller plant for the Kennedy Town Station. Two of the affected trees, namely Aleurites moluccana, are large trees with 13-15m height.
5.127 One of the large tree, are not transplantable due to its poor structure, unbalanced and unnatural tree form, moderate health condition, and general symptoms of weakness and decline. This tree has evidently passed its prime and entered the decline spiral. For all intents and purposes, it cannot be expected to make notable contributions in landscape or amenity terms in a recipient site.
5.128
The other affected large tree, situated
on a rather isolated ledge at the top of the cut slope is also not
transplantable due to the lack of road access for the large crane and the
truck.

The dimensions of the works
area have been kept to the minimum in order to reduce their impacts on trees
and other aspects of the HKU campus. Due
to the congested nature of the sites, there is limited scope to reduce the size
or alter the shape of the construction footprints and excavation limits.

There would be temporary loss of 3325m2 landscape amenity area in this neighbourhood, and temporary re-provision is not available in this neighbourhood.
5.138
In addition, there would be
impact on approximately 40 trees within the works area. Affected trees would be transplanted where
possible and practicable. However, there
are 8 number relatively large size specimen will suffer from deformation
seriously, namely, Brachychiton
acerifolium (

The registered Old and Valuable
Trees (registration no. LCSD CW21, CW22, CW23, CW24, CW25, CW26, CW27, CW28,
CW29), which is located at the south western corner and outside the proposed works
area, will not be affected.
5.140 However, at the junction of High Street and Eastern Street, there is one outstanding Chinese Banyan, Ficus microcarpa (25m Height, 23m spread) adjacent to the Park entrance, which is recorded as “ Old and Valuable Tree” with registration no. LCSD CW/16, will be affected by the works area. There are two nos. of registered Old and Valuable Trees (registration no. LCSD CW 17 & CW 18), which are located in the west side of the park will also be affected by the temporary work.
5.141 Besides, there are two nos. of registered Old and Valuable Trees (registration no. LCSD CW 19 & CW 20), which is closed to the works area, will be partially affected by the construction works and blasting vibrations nearby.

5.155 Potential landscape and visual impacts have been carefully considered during the development of the project design to (1) avoid impacts on important landscape resources including the Forbes Street tree wall (LR1.2) and KGV Park tree wall(LR1.6), as well as Old and Valuable Trees in the LCSD registry, as the first priority; and (2) locate, design and reduce physical extent of the works as far as possible, as well as identify mitigation measures, so as to minimize impacts on existing trees and open spaces, and to minimize the degree of visual impact, as proposed below. The recommended landscape and visual mitigation measures are illustrated in Figures. 5.6.1 to 5.6.3.
5.156 At the time of reporting, detail architectural and landscape design were not available. It is therefore recommended that landscape proposals and details of architectural design, chromatic treatment and visual and landscape mitigation measures for all above ground structures, including station entrances and vent shafts, to demonstrate that they would be sensibly designed in a manner that responds to the existing urban context be submitted to Planning Department for review. The proposals should be submitted 2 months before the commencement of project construction.

Operation Phase Landscape Impacts
5.161 The potential significance of impacts of LRs and LCAs during operating after mitigation is provided in Table 5.3.
5.162 Both assessments assume that appropriate mitigation measures as recommended in Table 5.4 & Table 5.5 will be implemented, with the full effect of the soft landscape mitigation measures accomplished by Year 10.
5.163
With mitigation measures taking
place, there will be no LRs or LCAs anticipated to have substantial adverse
impacts. The LRs and LCAs experiencing
residual adverse landscape impacts of moderate significance in the operation
phase are listed below and indicated in Table
5.3.
LR1.1 –
The
Forbes Street Playground will be affected by the construction of the permanent
structure of vent shaft and Kennedy Town Station Entrance C, which will occupy
most of the area currently occupied by the open space. All 47 trees will be
affected. Affected trees would be transplanted where
possible and practicable. There will be re-provision of
open space in current Kennedy Town Station. Thus the residual impact after mitigation
would be insubstantial in Year 10, as vegetation grows and established.
LR4.1 – Manmade Slope along
Due
to the permanent structure of the chiller plant at Kennedy Town Station and the
loss of the trees, the residual impact will be Moderate from Day 1. As vegetation
grows, the residual impact in Year 10 will be reduced to Slight as the trees
shall be fully covered.
University
Station
LR1.4 –
Although
the re-provision of LCSD playground will be compensated at the Kennedy Town
Swimming Pool site, there will be permanent loss of 145m2 of public open space, and the landscape element, namely, children play
facilities, passive landscape amenity area, sheltered seating space, Tai Chi
area in this neighbourhood. Thus the residual impact will be Moderate from Day 1
and in year 10.
LR2.6 – Amenity Area
between
Due
to the extent and scale of the permanent structure at the amenity area between
Po Fu Lam Road & Elevated Road and the permanent loss some of the existing vegetation, the
residual impact will be Moderate from Day 1 and in Year 10.
LR2.7 – Roadside
Planting at the West Gate of HKU
Due
to the extent and scale of the permanent structure at the West Gate of HKU and
the loss of the mature trees, the residual impact will be Moderate from Day 1. Affected trees would
be transplanted where possible and practicable, and as Ficus
microcarpa and Roystonea regia grow,
they shall be fully recovered in Year 10. However, the Delonix regia will suffer seriously from loss of form and amenity
value during the transplanting process and cannot be recovered to their
original tree form and umbrella shape, the residual impact in Year 10 will be moderate.
Sai Ying
Pun Station
LR1.5 –
5.164
The affected
5.165
The registered Old and Valuable
Trees (registration no. LCSD CW19, CW20, CW21, CW22, CW23, CW24, CW25, CW26,
CW27, CW28, CW29), which is located at the south western corner and outside the
proposed works area, will not be intact.
5.166 However, at the junction of High Street and Eastern Street, there is one outstanding Chinese Banyan, Ficus microcarpa (25m Height, 23m spread) adjacent to the Park entrance, which is recorded as “ Old and Valuable Tree” with registration no. LCSD CW/16, will be affected by the required works area in construction stage, and will be intact in operation stage.
5.167 Besides, there are two nos. of registered Old and Valuable Trees (registration no. LCSD CW 17 & CW 18), which is closed to the works area, will be partially affected by the construction works and blasting vibrations nearby during construction stage, and will be intact in operation stage.
LR1.7– Sai Woo Lane Playground
5.168 There would be permanent loss of landscape open space of 330m2 due to the SYP station Entrance A1 and the disabled lift facilities. Even though LCSD playground will be compensated at the existing Kennedy Town Swimming Pool site, there will be permanent loss of 330m2 landscape passive amenity area in this neighbourhood. There would be impact on approximately 44 trees within the required works area of approx. 2553m2. Majority of these trees are relatively small and will be transplanted, and will be fully recovered in year 10. However, the transplanting process will seriously scar the 5 number mature Ailanthus fordii during the crown pruning operations.
LR1.8 –
5.169
There would be permanently loss
of
LR1.9 –
Due
to the permanent loss of sitting-out facilities for the station entrance at B1
and the associated lift room and the loss of vegetation, the residual impact
will be Moderate from Day 1and in Year 10.
Visual Impact Assessment
Potential Sources
of Visual Impacts
5.170 The potential sources of landscape and visual impacts are described in the previous section.
Recommended Visual
Mitigation Measures in Construction and Operational Phase
5.171 The proposed visual mitigation measures in the construction and operational stage are listed in Table 5.4 & Table 5.5 which indicating the funding, implementation, management and maintenance parties.
5.172 The measures listed in above Table 5.4 & Table 5.5 should be adopted from the commencement of construction and should be in place throughout the entire construction period, whereas the operation phase mitigation measures should be incorporated in the detailed design stage and construction stage.
Prediction of
Significance of Visual Impacts in Construction phase
5.173 An assessment of the potential significance of the visual impacts during the construction and operational phases, before and after mitigation, is briefly described below, and listed in detail in Table 5.6. This follows the proposed methodology and assumes that the appropriate mitigation measures identified in Table 5.4 & Table 5.5 above would be implemented, and that the full effect of the soft landscape mitigation measures would be realised after year 10. Photomontages of the proposed development before and after mitigation in various stages are illustrated in Figures 5.7.1 to 5.7.8.
5.174 Residual visual impacts in the construction stage are illustrated in Figures 5.5.5. Adverse impacts of substantial significance during the construction phase would be experienced by the identified VSRs are indicated and described below, whereas all other VSRs would suffer either slight adverse or negligible residual visual impacts are listed in Table 5.6.

5.197 In total, approx. 13505 sq.m. open space and amenity area and over 350 nos. of trees will be affected by the construction of station entrances and vent shaft. The total number of trees affected would be subject to further change during the detailed design stage. It should be noted that any tree protection, tree transplanting and compensation tree planting proposals will be submitted to relevant government departments for approval. After the proposed mitigation measures have been implemented, majority of residual adverse visual impacts in the construction phase would be either moderate or slight.
Summary of Predicted Residual Landscape and Visual Impacts in Operational
Phase
5.198 Residual landscape impacts in the operational phase in listed in Table 5.3 and mapped in Figure 5.5.2 and Figure 5.5.4, whereas the residual visual impacts in construction phase are listed in Table 5.6, and mapped in Figure 5.5.6.
5.199 After the proposed mitigation measures have been implemented and the proposed soft landscape treatment has matured over 10 years, all residual adverse landscape and visual impacts in the operational phase would be of insubstantial significance, with the exception of the impact on:
Manmade slope along Pokfield Path (LR4.1) will be subject to the impact of slight significance. Two trees will be transplanted for the construction of chiller plant at Kennedy Town Station.
University Station
Hill Road Rest Garden (LR1.4), which will be subject to adverse impact of moderate significance due to permanent loss of 145 m2. Public open space, children play facilities, sheltered seating area, and landscape amenity area in this neighbourhood for the ground structure in operation phase.
Amenity Area between Po Fu Lam Road & Elevated Road (LR2.6), which will be subject to permanently loss of planting space for the construction of University Station Entrance C1, vent shaft Z1 & Z2 and chiller plant.
Roadside planting at West Gate of HKU (LR2.7), which will be subject to adverse impact of moderate significance due to the loss of approx. 15 number mature trees at the west gate of HKU for the UNI Entrance A and the seriously deformation of existing Delonix regia which cannot recover to its original status in 10 years. The transplanting operation will definitely scar the Delonix regia during the crown pruning works.
