·         an assessment of the acceptability of otherwise of the predicted residual impacts, according to the five criteria set out in Annex 10 of the EIAO-TM, namely beneficial, acceptable with mitigation measures, unacceptable or undetermined.

10.2.2               Identification of the Baseline Landscape Resources and Landscape Character Areas

10.2.2.1        The landscape baseline study identifies all LRs and LCAs located within 500m assessment area by site visits and desktop study of topographical maps, information databases, photographs and the ecology section. Aerial Photo is shown in Figure 10.1. Types of LR are mapped based on the area of their existing and major physical landscape elements and characteristics.

10.2.2.2        The Project has been divided into broad units of similar character based on a process of landscape characterisation which draws on the information gathered in the desktop study and site surveys. In addition, the Planning Department Study of Landscape Value Mapping of Hong Kong” and “Map of Land Utilization in Hong Kongare also considered. Typical elements which contribute to the landscape character include:

·         Local topography;

·         Extent and type of vegetation (including woodland, grassland, plantation, etc.);

·         Built form (including scale and appearance);

·         Patterns of settlement;

·         Wildness;

·         Land use;

·         Scenic spots;

·         Prominent watercourses; and

·         Cultural and religious features.

10.2.2.3        Details of the identified LRs and LCAs are presented and summarized in Table 10.4 and 10.5.

10.2.3               Broad Brush Tree Survey

10.2.3.1        As part of the EIA study carried out for the proposed development project, a broad-brush tree and vegetation survey (refer to Clause 2 Appendix I of EIA SB ESB-329/2020) has been carried out within the study area to identify the baseline conditions of the existing landscape resource and existing trees with the intention to minimize landscape impact. The broad-brush tree and vegetation survey is in aid of the aerial photos (Digital Orthophoto DOP5000 series of Lands Department (2018 Release)) and the ecology section, and based on the topographical survey conducted prior to the tree survey, and site visits to the Project site.

10.2.3.2        The survey areas are located at North Lantau Highway, Man Tung Road, Yat Tung Estate, Yu Tung Road and Shun Tung Road, the grouped tree survey plan, grouped tree survey schedule and grouped tree photo records are provided in Appendix 10.2. The key findings of the broad-brush tree and vegetation survey, including the number of existing trees, dominant species, general health condition and any plant species of conservation interest (including Old and Valuable Tree (OVTs), stonewall tree, Trees of Particular Interest (TPI) nor trees of particular value) has outlined in Section 10.5.7.

10.2.4               Sensitivity of Landscape Resources and Landscape Character Areas

10.2.4.1        A qualitative description of LRs and LCAs has been provided and their extent quantified either by area or length. The sensitivity of the LRs and LCAs are evaluated and rated taking into account the following criteria:

·         quality of landscape characters/ resources;

·         importance and rarity of special landscape elements;

·         ability of the landscape to accommodate change;

·         significance of the change in local and regional context, and

·         maturity of the landscape.

10.2.4.2        The sensitivity ratings are classified as below:

High:

LR or LCA of high quality and value, which is sensitive to even relatively small changes

Medium:

LR or LCA of moderate quality and value, which is reasonably tolerant to change

Low:

LR or LCA of low quality and value, which is largely tolerant to change

10.2.5               Identification of Potential Sources of Impact

10.2.5.1        The permanent or temporary construction works and the operation of the railway extension may generate potential impacts to the existing landscape environment. Any potential sources of impact related to the Project have been identified. Based on preliminary design information, the major impacts will be generated from the following during construction and operational phases of the Project:

Construction Phase

·         Site formation and construction of turnouts for realignment of the existing at grade Tung Chung Line (TCL) section from Tuen Mun Chek Lap Kok Link connection point to south of Ying Tung Estate;

·         Site formation, site foundation and construction of above-ground Tung Chung East (TCE) Station and associated facilities;

·         Site excavation, cut-and-cover and backfilling for the tunnel launching and retrieval shafts for the underground tunnel section for Tung Chung West (TCW) extension alignment;

·         Site excavation, open cut/cut-and cover and backfilling for underground TCW Station and the associated facilities;

·         Site excavation and construction of Emergency Access Point (EAP)/ Emergency Egress Point (EEP);

·         Temporary works areas for site offices and material storage; and

·         Barging point.

Operational Phase

·         EAP/ EEP Building; and

·         TCE Station and TCW Station as well as the associated station entrances and vent shaft structures.

10.2.6               Magnitude of Change to Landscape Resources and Landscape Character Areas

10.2.6.1        The assessment of “Magnitude of Change” for landscape impacts considers the following criteria:

·         compatibility of the Project with the surrounding landscape;

·         duration of impacts under construction and operational phases;

·         scale of development; and

·         reversibility of change.

10.2.6.2        The magnitude of change is considered separately for the construction phase and operational phase; the 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

10.2.7               Impact Significance in relation to LRs and LCAs

10.2.7.1        The assessment of the “Impact Significance Threshold before Mitigation” for landscape impacts is considered during the construction and operational phases (Day 1 and Year 10) by synthesizing the “Sensitivity” and “Magnitude of Change” for various LRs and LCAs according to Table 10.1. The degree of significance has been divided into four thresholds identified below:

Substantial:

Adverse/ beneficial impact where the proposals 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

Insignificant:

No discernible change in the existing landscape quality

10.2.8               Identification of Potential Landscape Mitigation Measures

10.2.8.1        Identification of potential mitigation measures, alternative design, and/or alignment, and/ or construction methodologies that will make the Project more compatible with its landscape setting. Alternative design, and/ or alignment, and/ or construction methodologies that will avoid or reduce landscape impacts are considered before adopting other mitigation measures. Design considerations/ options that have been explored before arriving to the recommended alignment as discussed in Section 2 whilst Section 10.9 has discussed how the Project is compatible with its local context.

10.2.8.2        Mitigation measures are considered for both construction and operational phases to prevent or minimise unavoidable adverse impacts and/ or generate beneficial long-term impacts. To ensure their effectiveness throughout the construction and operational phases, the relevant responsible parties for the on-going management and maintenance of the proposed mitigation measures have been identified.

10.2.9               Residual Landscape Impact Assessment Methodology

10.2.9.1        This part of the assessment describes any residual adverse landscape impacts to LRs and LCAs. Residual impacts are those which remain after commissioning of the development (operation Day 1 & Year 10) with mitigation measures implemented.

10.2.9.2        The level of impact is derived from the magnitude of change which the Project will cause to the LR or LCA taking into account its ability to tolerate change and effectiveness of mitigation measures.

10.3                    Visual Impact Assessment Methodology

10.3.1               General

10.3.1.1        The assessment area for visual impact assessment is defined in accordance with EIAO Guidance Note No. 8/2010, the EIAO-TM, particularly Annexes 10 (Criteria for Evaluating Visual and Landscape Impact, and Impact on Sites of Cultural Heritage) and 18 (Guidelines for Landscape and Visual Impact Assessment). It includes the areas within 500m from the project boundary and within the Visual Envelope (VE) that could potentially see the Project and defines the limit of its visibility.

10.3.2               Identification and Plotting of the Visual Envelope

10.3.2.1        The assessment area is defined by the VE which includes all the points from which the scheme proposals may be visible, comprising the viewshed formed by natural/ manmade features such as ridgelines, built form or areas of woodland/ large trees. This area is identified through a combination of detailed field surveys, desktop study and review of aerial photography.

10.3.2.2        The VE includes the areas of North Lantau, Chek Lap Kok and Hong Kong International Airport (HKIA). TCL realignment are fairly enclosed by prominent green hill slopes in close proximity to the south, by the inshore water immediately to the north and west, and by the Tung Chung New Town Extension (TCNTE) East to the north while TCW extension alignment is enclosed by Yat Tung Estate in close proximity to the east, Mun Tung Estate to the south, Wong Lung Hang estuary to the west and Tung Chung Bay to the north. 

10.3.3               Identification of VSRs within the Visual Envelope

10.3.3.1        The VSRs represent the people who would reside within, work within, play within, or travel through. The VSRs for the visual impact assessment are identified within the VE.

10.3.3.2        The selection of VSRs have considered the latest locations of above-ground structures including stations, vent shaft structures, station entrances, EAP/ EEP, etc. 

10.3.4               Sensitivity of VSRs

10.3.4.1        VSRs within the VE during the construction and operational phases of the development are identified. Views from these points are recorded, described and the sensitivity assessed.

10.3.4.2        The assessment of sensitivity is based on the quality and extent of the existing view. The factors affecting the sensitivity of receivers for evaluation of visual impacts include the following:

·         The type of VSRs, which is classified according to whether the person is at home, at work, at play, or travelling.  Those who view the impact from their homes are considered to be highly sensitive as the attractiveness or otherwise of the outlook from their home will have a substantial effect on their perception of the quality and acceptability of their home environment and their general quality of life.  Those who view the impact from their workplace are considered to be only moderately sensitive as the attractiveness or otherwise of the outlook will have a less important, although still material, effect on their perception of their quality of life.  The degree to which this applies depends on whether the workplace is industrial, retail or commercial.  Those who view the impact whilst taking part in an outdoor leisure activity may display varying sensitivity depending on the type of leisure activity.  Those who view the impact whilst travelling on a public thoroughfare will also display varying sensitivity depending on the speed of travel.

·        Other factors which are considered (as required by EIAO Guidance Note 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.

10.3.4.3        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.

10.3.4.4        The duration of the impact during construction and operation is determined based on the following ratings:

Construction:

 

Temporary

Construction works that will only be visible for a short duration of the overall construction period

Permanent

Construction work will be visible throughout the whole construction period

Operation:

 

Permanent

Views of the Project that will remain permanently open to the view

10.3.5               Prediction of Visual Impact Based on Field of View

10.3.5.1        The visual impact of a development can be quantified by reference to the degree of influence on a person’s field of vision referencing the typical parameters of human vision based on anthropometric data. These data provide a basis for assessing and interpreting the impact of a development by comparing the extent to which the development would intrude into the centre field of vision (both vertically and horizontally, refer to Appendix 10.1 - Prediction of Visual Impact Based on Field of View).

10.3.6               Identification of Potential Sources of Visual Impact

10.3.6.1        These are the various elements of the construction works and operational procedures that could generate visual impacts. They will create varying levels of visual impact due to factors such as visual obstruction, degradation of the quality of existing views and incompatibility with the surrounding landscape setting.

10.3.7               Magnitude of Change to VSRs

10.3.7.1        Magnitude of change to an existing view can be determined by a number of interrelated factors, including:

·         compatibility of the Project with the surrounding landscape;

·         duration of impacts under construction and operational phases;

·         scale of development;

·         reversibility of change;

·         viewing distance; and

·         potential obstruction of view.

10.3.7.2        The magnitude of changes at different stages of the construction and operational phases are considered separately, with ratings set out 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

10.3.8               Impact Significance in relation to VSRs

10.3.8.1        The impact significance to VSRs deals with the prediction of “Impact Significance Threshold before Mitigation” for visual impacts through combining the “Sensitivity to Change” and “Magnitude of Change” for various VSRs according to Table 10.2 below.

10.3.8.2        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 a barely perceptible deterioration or improvement in existing visual quality

Negligible:

No discernible change in the existing visual quality

10.3.9               Identification of Potential Visual Mitigation Measures

10.3.9.1        Identification of potential mitigation measures, alternative design configurations, design and construction methodologies that will make the Project visually more compatible with its landscape setting are examined before adopting other mitigation measures. Mitigation measures are considered for both construction and operational phases to prevent or minimise unavoidable adverse impacts and/ or generate beneficial long-term impacts.

10.3.10          Residual Visual Impacts Assessment Methodology

10.3.10.1   This part of the assessment indicates the influence on VSRs after applying mitigation measures, assuming that all proposed measures and guidelines would be fully implemented. Residual impacts are those impacts which remain after commissioning of the development (operation Day 1 & Year 10) with mitigation measures implemented.

10.3.10.2   The level of impact is derived from the magnitude of change which the Project will cause to the existing view and its ability to tolerate change, i.e. the quality and sensitivity of the view taking into account the beneficial effects of the proposed mitigation.

10.3.11          Cumulative Impact Assessment

10.3.11.1   This section reviews the projects currently in progress or planned/committed developments nearby the site boundary. Construction of these projects will result in cumulative landscape and visual impacts including the loss of landscape resources and landscape character, and the degradation of visual quality.

10.3.11.2   Mitigation measures to address the cumulative impacts would be incorporated into the design of each project. The resulting changes to the existing landscape character, landscape resources and visual quality have been taken into account in the assessment. Cumulative impacts from these projects are therefore taken into account through their inclusion in the baseline conditions.

10.3.12          Overall result of the Landscape and Visual Impact Assessment

10.3.12.1   An overall assessment is made on the development based on the identified landscape and visual impacts as follows:

Table 10.3 Residual impact assessment methodology

Overall Result of LVIA Assessment

Description

Beneficial

The impact is beneficial if the Project will complement the landscape and visual character of its setting, will follow the relevant planning objectives and will improve overall and visual quality

Acceptable

The impact is acceptable if the assessment indicates that there will be no significant effects on the landscape, no significant visual effects caused by the appearance of the project, or no interference with key views

Acceptable with mitigation measures

The impact is acceptable with mitigation measures if there will be some adverse effects, but these can be eliminated, reduced or offset to a large extent by specific measures

Unacceptable

The impact is unacceptable if the adverse effects are considered too excessive and are unable to mitigate practically

Undetermined

The impact is undetermined if significant adverse effects are likely, but the extent to which they may occur or may be mitigated cannot be determined from the study. Further detailed study will be required for the specific effects in question

10.4                    Review of Planning and Development Control Framework

10.4.1               General

10.4.1.1        A review of the existing planning and development framework for the Project Site and its context is conducted in order to:

·         Identify issues/ conflicts in relation to the Project;

·         Identify the potential resources and sensitive receivers; and

·         Identify any synergies with the proposed works and the surroundings.

10.4.1.2        The following statutory plans and departmental plans fall within the 500m assessment area:

·         The approved Tung Chung Extension Area OZP No. S/I-TCE/2;

·         The approved Tung Chung Town Centre Area OZP No. S/I-TCTC/24;

·         The approved Tung Chung Valley Outline Zoning Plan (OZP) No. S/I-TCV/2;

·         The adopted Tung Chung Extension Area ODP No. D/I-TCE/1;

·         The adopted Tung Chung Town Centre Area (North) ODP No. D/I-TCTCN/1;

·         The adopted Tung Chung Town Centre Area (South) ODP No. D/I-TCTCS/1; and

·         The adopted Tung Chung Valley ODP No. D/I-TCV/1.

10.4.1.3        The review of OZPs is not only included a review of the plans, but also the Notes which form part of these plans and the Explanatory Statements which accompany the plans.

10.4.1.4        No natural woodland or high landscape value found will be in direct conflict with any work sites/ areas. All aboveground work areas will fall within various zonings on the OZPs, including "Government/Institution or Community" ("G/IC"), "Open Space" ("O"), "Village Type Development" ("V") and "Other Specified Uses" annotated "Railway Station" ("OU(Railway Station)"), Major Road and Junction (MRDJ), "Residential (Group A)" ("R(A)") and “Residential (Group B)” ("R(B)1"). The layout has been superimposed onto the existing OZP to determine whether there is an effect on the zoned use in Figure 10.2.

10.4.2               General Description of the Project Site

10.4.2.1        As discussed in Section 2, the Project consists of east and west sections.  The eastern section is the proposed realignment of the existing TCL and the provision of a new at-grade TCE Station which are located along the TCNTE new reclamation area of TCE.  The western section is the tunnel connecting the existing Tung Chung Station (TUC) with the new TCW Station to the west of Yat Tung Estate.

10.4.2.2        While the eastern section is located on existing developed area, the western section will go underneath Rocky Lion Hill along Shun Tung Road and the coast of Ma Wan Chung before reaching the new TCW Station west of Yat Tung Estate.  While the entire extension alignment would be underground, there are aboveground works sites/works areas at the tunnel boring machine (TBM) launching and retrieval shafts, the cut-and-cover works site for the TCW Station box, EAP/EEP, station entrance, vent shaft structures, site reinstatement, material storage and site offices.

10.4.2.3        In addition, a north-south visual corridor was planned to connect the TCE Station to the northern end of the TCNTE reclamation area, this visual corridor is one of the planning considerations during the preparation of the Recommended Outline Development Plan (RODP) adopted in the approved EIA report for TCNTE. The current design of the TCE Station has maintained the same planning approach to align with this intention of the visual corridor.

10.4.3               Design Intention of the Proposed Developments

Compatibility to the TCNTE Development

10.4.3.1        The design of both the TCE and TCW Stations has followed the design intention recommended in the TCNTE EIA Study as far as practicable. It would help to maintain the design initiative and improve compatibility with the TCNTE development.

Design Intentions of Visual Enhancement

10.4.3.2        The development of proposed station, footbridge and entrances structures incorporate the design intentions of integrating with the planned environ of Metro Core District as a gateway to Tung Chung East and regional commercial hub and creating an interesting and vibrant pedestrian environment by various design features.

Minimization of the Above-ground Structures

10.4.3.3        The above-ground structures have been proactively designed to alleviate the bulk of the structures. In addition, transparent glass panels have also been considered to allow natural light to penetrate into the structures. These would help to reduce the associated visual impacts.

Avoidance of Mature Woodland

10.4.3.4        The design has critically reviewed the possibility of the location of EAP/ EEP to avoid loss in mature woodland. After a due review on various design requirements, the location of EAP/ EEP has located to an artificial slope at Shun Tung Road at which only plantation is identified. Hence, the landscape and visual impact is minimized.

Adoption of Street Level Planting

10.4.3.5        Small plants are planted to form a partial screen to visually buffer the EAP/ EEP. All plants should be of reasonable size to improve compatibility with the surrounding environment to alleviate landscape and visual impacts.

     Provision of Green Roof

10.4.3.6        The green roof planting without individual containers will be adopted on the top of the architecture of both TCW and TCE Stations. Species will be selected with subtle gradation and modulation of their colours, formal architecture of their leaves and flowers and their suitability.

10.5.3               Sensitivity of Landscape Resources

10.5.3.1        LRs affected by the Project within 500m of the subject site have been identified and mapped using a combination of aerial photography followed by on site verification. Each component affecting the sensitivity of the LR have been reviewed in relation to:

·         Quality of landscape character/ resources;

·         Importance and rarity of special landscape elements;

·         Ability of the landscape to accommodate change;

·         Significance of the change in local and regional context; and

·         Maturity of the landscape.

10.5.3.2        Physical LRs are the natural components of the landscape and include geology, topography, soil, vegetation, and hydrological features. Each LR possesses a varying sensitivity to development. Therefore, the 500m assessment area incorporates a diversity of LRs of greatly varying extents and sensitivities.

10.5.7               Review of the Broad-Brush Tree and Vegetation Survey Records

10.5.7.1        A broad-brush tree survey and vegetation survey as shown in Appendix 10.2 was conducted by the Project Proponent within the proposed works sites and work areas between April and July 2020. The survey methodologies were in accordance with the requirements in LAO PN 2/2020, DEVB TCW No. 4/2020 – Tree Preservation and DEVB TCW No. 5/2020 – Registration of Old and Valuable Trees, and Guidelines for their Preservation.

10.5.7.2        According to the board tree and vegetation survey results, about 3,200 nos. of existing trees are identified within the works sites/ works areas and none of these are Registered Old and Valuable Trees (OVTs), stonewall tree nor Trees of Particular Interest (TPI). However, 17 nos. of protected species (under The Forests and Countryside Ordinance (Cap.96)) are recorded (including 12 Lagerstroemia speciosa大花紫薇 and 5 Magnolia denudata 玉蘭) during the survey. The overall health conditions and the maturity of the surveyed existing trees are rated as medium. Dominant tree species include Litchi chinensis 荔枝, Schima superba木荷, Livistona chinensis 蒲葵, Casuarina equisetifolia木麻黃and Ficus microcarpa. 細葉榕. Most of the surveyed existing trees are found within the Agricultural Land, Urban Development and Road, Urban Infrastructure and Major Transport Corridor.  

10.6                    Visual Baseline Study

10.6.1               Visual Baseline Condition

10.6.1.1        The visual assessment area is defined by the VE which is the area that any part of the proposed project can be seen from, and is generally the viewshed formed by natural/ manmade features such as ridgelines, built form or areas of woodland/ large trees. The VE may contain areas, which are fully visible, partly visible and non-visible from the project.

10.6.1.2        The VE includes the areas of North Lantau, HKIA and Chek Lap Kok. The proposed at-ground structures with its vent shaft facilities are mainly erected within both existing and future urban areas, which include Yat Tung Estate, artificial slopes along Shun Tung Road, and future TCNTE. Hence, the proposed work areas are fairly enclosed by prominent foothill in close proximity to the south, by the inshore water immediately to the northwest, and by the existing Tung Chung Town and future TCNTE to the north.

10.6.2               Identification of VSRs

10.6.2.1        The selection of VSRs have considered the latest locations of at-ground structures including stations, station entrance, vent shaft structures, EAP/ EEP, etc. Among the VE, 20 potential VSRs are identified.

10.7                    Landscape and Visual Impact Assessment before Mitigation

10.7.1               Aims of Review

10.7.1.1        A review of the existing and planned development framework for the proposed development and context has been conducted to:

·         Assist with identification of existing landscape resources and potentially sensitive receivers;

·         Highlight potential issues for neighbouring planned land uses;

·         Optimise the compatibility of the development with the surrounding land uses.

10.7.2               Sources of Landscape and Visual Impact

10.7.2.1        As mentioned in Section 10.2.5, there are number of construction and temporary works within the project boundary. Some landscape and visual impacts would therefore be generated.

10.7.2.2        During the construction stage, potential landscape visual impacts will be caused by the following:

·         Construction Works – construction of the at-ground structures, such as realignment of the existing at-grade TCL section from Tuen Mun Chek Lap Kok connection point to south of Ying Tung Estate, TCE Station, TCW Station, station entrance, vent shaft structures, EAP/ EEP, would generate landscape and visual impacts due to the appearance of construction activities and loss of vegetation cover;

·         Temporary Works – temporary works including site offices, boundary fencing/ hoarding, parking areas, storage of construction equipment and mechanical plant, as well as operation of barging point, would generate landscape and visual impacts as a result of these operation intruding into existing view and generally low aesthetical value of these types of structures; and

·         Night-time Lighting – night-time lighting such as security floodlights of the construction site would cause adverse visual impacts.

10.7.2.3        During operational phase, the potential residual landscape and visual impacts would be related to the permanent loss of landscape resources and above-ground structures:

·         Operation of TCE Station and TCW Station with Associated Facilities – operation of both stations with the associated facilities such as EAP/EEP buildings, station entrances, vent shaft structures, would generate visual impacts due to the visibility of new structures; and

·         Residual Impacts – residual impacts from loss of trees, vegetation and recreational facilities during the construction phase would generate landscape impacts and visual impacts.

10.7.4               Impacts on Tree Identified after Board Tree Survey

10.7.4.1        The broad tree and vegetation survey have identified 17 nos. of protected species are recorded (12 Lagerstroemia speciosa大花紫薇, and 5 Magnolia denudata玉蘭) during the survey. 12 nos. of Lagerstroemia speciosa 大花紫薇 can be found at the roadside amenity planters near Ping Yat Estate and Yu Tung Road; and 5 nos. of Magnolia denudata玉蘭are recorded along Shun Tung Road. Based on the development layout, there is no tree of conservation status or particular interest will be affected by the proposed development. 

10.7.4.2        Based on the development layout and the distribution of the existing trees, this preliminary tree impact assessment suggests that about 30% of the trees within the tree assessment boundary could be preserved. Regarding to the development layout of railway line extension, most of the tree preservation are within the LR of Secondary Woodland in TCW. Almost 70% of trees within the development boundary are affected under the LRs of Agricultural Land (LR5), Plantation (LR3), Urbanised Development (LR15) and Road and Infrastructure (LR13b). A large scale of Agricultural land at TCW will be affected by sites designated for the future railway station.

10.7.4.3        A summary of the breakdown of trees that would need to be felled / transplanted is given in Table 10.9 below.  The location of different construction areas is shown in Figure 10.9.

10.7.6               Summary of Significance of Impacts on Landscape Resources

10.7.6.1        In summary, no LRs with high sensitivity will be in conflict with any proposed work areas.

10.7.6.2        Potential landscape impacts to the LR5 would be arisen from the site formation works for the proposed vent shaft structures and TCW Station, which would be induce temporary and reversible impact to the existing agricultural land. Given to its medium physical extent of impact and its medium sensitivity, the magnitude of change is considered to be Large during both construction and operational stage. Therefore, this LR will experience Moderate/ Substantial adverse impacts for both stages.

10.7.6.3        Small portions of LR3 Plantation will be in direct conflict with the EAP/EEP. Given only small portions of LR3 will be affected, the magnitude of change of the LRs are rated as Small during both construction and operational stages. Since the proposed development will have poor compatibility with surrounding landscape with irreversible changes, LR3 are predicted to experience Moderate impacts during both stages.

10.7.6.4        Realignment of the existing at-grade TCL section will be erected at LR 13a Major Transport Corridor. As the proposed realignment works would induce temporary and irreversible landscape impact, hence the magnitude of change is considered as Intermediate during construction stage. Consider the man-made nature of this LR and the excavated area will be reinstated after the construction, the magnitude of change is considered to be Small during operation stage. Hence, this LR will experience Moderate adverse impacts during construction stages and Slight impact during operation stages.

10.7.6.5        The proposed TCW station, with temporary works areas included barging point, will be fallen within LR15 Urbanised Development. As the majority of the LR will be preserved, the overall compatibility with surrounding landscape is fair. The magnitude of change is therefore considered to be Small. The LR will also experience Slight adverse impacts during both stages.

10.7.6.6        The proposed TCE Station will be erected at the existing reclaimed land LR16 Ongoing Reclamation Area. It is compatible with the surrounding landscape as the adjacent reclaimed land is for development as well during construction stages. The magnitude of change is regarded to be Negligible.  After construction, the landscape impact is considered to be permanent and the change is irreversible.  Due to the small proportion of the LR will be affected with the good compatibility, the magnitude of change is regarded to be Small. Hence, the LR is predicted to experience Insignificant adverse impact at construction and Slight impact after construction.

10.7.6.7        Several temporary works will be scattered within LR13b Road & Urban Infrastructure, and LR14 Village Type Development. The landscape impacts will be only caused before operation. For LR13b Road & Urban Infrastructure, given it is compatible with the surrounding landscape as the adjacent landscape, the magnitude of change is considered to be Negligible. For LR14 Village Type Development, as the overall sensitivity is rated as medium. And the magnitude of change is regarded to be Small given only a small portion will be affected. Hence, as different magnitude of changes, the LR13b and LR14 are predicted to experience Insignificant and Moderate impact respectively.

10.7.6.8        The remaining LRs will experience insignificant impacts, as the LRs will not be affected by the Project.

10.7.8               Summary of Significance of Impacts on Landscape Character Plans

10.7.8.1        LCA4 Coastal Upland and Hillside Landscape is considered as high sensitivity due to the natural landscape. However, as the majority of the LCA will be preserved, the magnitude of change is therefore considered to be Small. The LCA will experience Moderate adverse impacts during both construction and operational phases.

10.7.8.2        Realignment of the existing at grade TCL section will be erected at LCA8 Transportation Corridor Landscape, the medium extent of the existing landscape area would be affected by the construction works, the magnitude of change is considered as “Intermediate” during construction stage. However, the proposed realignment is considered to be compatible with the existing railway, there will be no significant changes on this LCA after the construction, the magnitude of change is considered to be ‘Small’ during operation stage. Hence, the LCA is predicted to experience Moderate adverse impact at construction and Slight impact after construction.

10.7.8.3        The proposed TCE station with several temporary work areas (included barging point) will be erected at the existing reclaimed land LCA7 Reclamation/ Ongoing Major Development Landscape. It is fully compatible with the surrounding landscape as the adjacent reclaimed land is for development as well during construction stages, and hence the magnitude of change is regarded to be Negligible.  After construction, the landscape impact is considered to be permanent and the change is irreversible.  Due to the small proportion of the LCA will be affected with the good compatibility, the magnitude of change is regarded to be Small. Hence, the LCA is predicted to experience Insignificant adverse impact at construction and Slight impact after construction.

10.7.8.4        The proposed TCW station and some temporary works areas will be within LCA9 Mixed Modern Comprehensive Urban Development Landscape. As the majority of the LCA will be preserved, the overall compatibility with surrounding landscape is fair. The magnitude of change is therefore considered to be Small. The LCA will also experience Slight adverse impacts during both stages.

10.7.8.5        A temporary work area next to Ma Wan New Village and a small extent of TCW Station will be erected within LR10 Urban Peripheral Village and Rural Fringe Landscape. As the overall sensitivity is rated as medium. And the magnitude of change is regarded to be Small given only a small portion will be affected. Hence, the LCA is predicted to experience Moderate impact during both phases.

10.7.8.6        The remaining LCAs will not have any impacts caused by the Project.


10.7.9               Magnitude of Change to VSRs

10.7.9.1        The potential sources of visual impact due to the Project are described in Section 10.2.5. The magnitude of visual change depends on a number of factors as outlined in the methodology of visual assessment, and with considering of the potential sources of visual impact above. The magnitude of change on VSRs is presented in Table 10.13 below.

10.7.11          Summary of Significance of Impacts on VSR before Mitigation Measures

10.7.11.1   Moderate visual impacts would be experienced by VSR2 Planned Tung Chung New Town Extension, VSR10 Tung Chung Crescent, VSR11 Fu Tung Estate, VSR16 Yat Tung Estate, VSR18 Mun Tung Estate VSR19 Ha Ling Pei Village and VSR21 Future Tung Chung West Promenade, which have direct and close view of the proposed at-grade structures, comprise TCE Station, TCW Station, station entrances, EAP/EEP and tentative works site respectively. The visual impacts would be caused by the construction works involving construction of buildings and structures during construction phase, and full visibility operation of new stations with its vent shaft structures and station entrances, which would cause small/ intermediate magnitude of change due to the small/ medium scale of development. Based on their high visual sensitivity as residential VSRs, moderate visual impact would be generated.

10.7.11.2   Furthermore, VSR3 Ying Tung Estate would also experience moderate visual impacts during construction stage. However, given the blockage of the future high-rise buildings in TCNTE, the impact significance would be considered as insignificant after operation. For VSR5 Caribbean Coast, given the distant view from this viewpoint, while the construction and operation of the proposed station would have fair/ good combability with surrounding landscape, e.g. construction activities on TCNTE and the Transportation Corridor nearby, this VSR would experience insignificant visual impacts during operational stage. However, one of the temporary work areas for the launching/ retrieval shaft will be erected in a close distance, which would cause a moderate visual impact for the resident at Caribbean Coast during construction stage.

10.7.11.3   Apart from the construction and operation of the proposed TCW and TCE Stations with its vent shaft structures and station entrances, a series of temporary works sites/ areas and barging point would also generate visual impacts during construction stage. Hence, moderate visual impacts would be experienced by VSR6 Sheraton Hong Kong Tung Chung Hotel, VSR7 Coastal Skyline, VSR13 Yu Tai Court, and VSR14 Ma Wan New Village, which would have close view of the temporary construction works sites/ areas. Based on their high visual sensitivity as residential VSRs, moderate visual impacts could be caused during construction stage. As the temporary work area will be returned for development after operation, no visual changes would be caused during operational stage.

10.7.11.4   Slight visual impacts would be experienced by several VSRs facing to the proposed Stations. VSR1 North Lantau Highway, VSR15 Yu Tung Road and VSR22 Tung Chung Line & Airport Express Line represent passengers and drivers through the main roads, which would have slight sensitive to any visual change. Given small scale of the development, the VSRs would experience slight visual impacts during both construction and operational phases.

10.7.11.5   Although with a medium visual sensitivity, slight visual impact would be predicted due to small magnitude of change for the recreational VSR 12 (Lantau North Country Park). This VSR would have a panoramic view of TCNTE. Given the small scale of development would be located at the far distance, the magnitude of change would be considered as small, slight adverse impact would be generated during both phases.

10.7.11.6   Insignificant impact would be experienced for the following VSRs which would have negligible changes of view in relation to the development. VSR4 The Visionary, VSR8 Chek Lap Kok Airport Island and VSR9 Scenic Hill would experience insignificant change because having long viewing distances, the proposed structures or temporary works would not be noticeable from these VPs.

10.7.11.7   Given the fully blockage of roadside tree planting or existing building elements, the proposed stations or any temporary work areas cannot be seen by recreational VSR17 Tung Chung Fort and residential VSR20 Ma Wan Chun Village. No visual change is expected.

10.8                    Landscape and Visual Mitigation Measures

10.8.1               General

10.8.1.1        The previous sections have identified the potential landscape and visual impacts due to the proposed stations and its vent shaft structures. A series of mitigation measure has been formulated in order to alleviate the effects of these impact where possible. It should be noted that design measures with intention to minimise overall landscape and visual impacts due to the development have also been incorporated into the layout plans during planning and design stages. This section will describe the summary of proposed mitigation measures incorporated into development layout plans to minimise adverse impacts.

10.8.2               Proposed Landscape and Visual Mitigation Measures

10.8.2.1        During the construction and operational phases, the mitigation measures listed, and responsibility matrix are provided in Table 10.15, which has been be considered to address any potential residual landscape and visual impacts. The construction and operational mitigation measures focus on the methods of preservation or minimisation of potential impacts, will take effect during both phases.

[1]    CM – Construction Mitigation.

[2]    OM – Operational Mitigation.

[3]    The management / maintenance responsibility, in general, following DEVB TCW No. 6/2015 subject to agreement. The tree numbers are indicative only and the exact numbers are subjected to approval of TPRP.

10.8.2.2        The proposed mitigation measures are summarised below:

·         CM1 Tree Preservation – existing trees to be retained within the Project Site shall be protected carefully during construction. A detailed tree survey will be carried out for the Tree Preservation and Removal Proposal (TPRP) to be submitted to relevant government departments for approval in accordance with DEVB TCW No. 4/2020 at the later detailed design stage of the Project. Besides, Tree Protection Zone (TPZ) shall be set up throughout the construction stages;

·         CM2 Tree Transplanting – trees unavoidably affected by the Project works shall be transplanted where practical. Approx. 170 nos. of trees are proposed to be transplanted at Shun Tung Road and Yu Tung Road as shown in Appendix 10.3. The Project Proponent would implement the tree transplantation as proposed in the TPRP to be submitted to relevant government departments for approval in accordance with DEVB TCW No. 4/2020 at the later detailed design stage of the Project;

·        CM3 Landscape Reinstatement – all hard and soft landscape areas disturbed temporarily during construction shall be reinstated on like-to-like basis as far as possible, to the satisfaction of the relevant Government Departments.

·         CM4 Lighting Control – all security floodlights for construction sites should be carefully controlled to minimize light pollution and night-time glare to nearby users. The lighting installation will follow the Charter on External Lighting and Guidelines on Industry Best Practices for External Lighting Installations promulgated by Environment Bureau (ENB) as far as practicable.

·         CM5 Erection of Screen Hoarding – construction site hoarding should be erected around the work sites and work areas to screen pedestrian level views into the construction area from visual sensitive receivers. Hoarding design shall be compatible with the surrounding context as far as practicable.

·         CM6 Optimization of Construction Areas Construction areas’ control shall be enforced, where possible, to ensure that the landscape and visual impacts arising from the construction activities are minimised.  It includes optimising the extent of working areas and temporary works areas, management on storing and using the construction equipment and materials, and consideration of detailed schedules to shorten the construction period.

·         OM1 Compensatory Tree Planting – It should be noted that the design of the stations and any above-ground structures such as entrances have been duly optimised to minimise the footprint and hence the associated landscape and visual impacts. Based on the development layout, approx. 2,100 no. of trees are proposed to be felled and compensated.  However, there would not be sufficient space for the replanting of trees within the station areas.  Nevertheless, the Project Proponent would implement the compensatory planting as proposed in the TPRP to be submitted to relevant government departments for approval in accordance with DEVB TCW No. 4/2020 to compensate for the trees to be felled. As far as practicable, implementation of compensatory tree planting should be of a ratio not less than 1:1 in terms of number of trees removed including dead trees, but excluding trees of undesirable species. Sufficient space should be provided for the compensatory trees from establishment to maturity to maximise tree health and stability. A number of possible compensatory tree planting locations have been identified as summarised below. The Project Proponent will actively liaise with all the relevant departments throughout the TPRP process.

(a)   Tung Chung Area 113;

(b)   TCE Station;

(c)   Tung Chung Crescent;

(d)   Shun Tung Road;

(e)   TCW Station;

(f)    Yu Tung Road;

(g)   Hillside area near Tung Chung Road;

(h)   Planned residential and commercial development atop Siu Ho Wan Depot; and

(i)     Other areas to be identified.

·         OM2 Optimise Greening Provision on Structure – implement greening measures that could alleviate the landscape and visual impacts of new development and help the development blend in with its surrounding landscape, which comprise implement rooftop greening to all above-ground structures against exposed building surfaces as far as possible, to reduce any undesirable impacts.  According to the current design as shown in Appendix 10.3, the following greening provision would be implemented and these would be further revisited and refined during the subsequent design stage and throughout the construction period.

Greening Provision

Area (m2), approx

Green roof at TCE Station

3,200

Green roof at TCW Station

900

Green roof at EAP/ EEP

600

·         OM3 Landscape Integration and Screen Planting plant tree screen/ buffer trees and shrubs to screen proposed stations and its vent shaft structures where appropriate. Approx. 8 no. of trees are proposed as a buffer planting. This measure would form part of the compensatory planting and will improve compatibility with the surrounding environment. According to the current design as shown in Appendix 10.3, a strip of street planting besides EAP /EEP along Shun Tung Road would be implemented. The extent and intensity would be further revisited and refined during the subsequent design stage and throughout the construction period.

·         OM4 Architectural Aesthetic Design of Built Structures – ensure the building massing is compatible with its surroundings. To improve visual amenity, the following architectural aesthetic design features as shown in Appendix 10.3 have been incorporated.

(a)   The architectural character of the proposed structures in terms of form, material and surface detailing shall be complementary to the planned sub­urban character of TCE/natural-rural setting of TCW.

(b)   The proposed vent shaft structures shall adopt a mild and subdued design to minimize potential visual impact to nearby residents/VSRs.

(c)   The façade of the proposed pedestrian links/footbridges and TCE station shall adopt atheistic pleasing design and enhance arrival/pedestrian experience, especially to the VSR at major open space (i.e. the planned metro plaza at Area 113).

(d)   For the above-ground structure of the station entrances in TCW Station, the architectural design has incorporated transparent glass panels which would alleviate the bulk of the structure and allow natural light to penetrate into the station entrances.  This would help to reduce the visual impacts of the station entrances.

(e)   For the vent shaft structures in TCW, the building height would be kept to minimum.  Given the natural environmental in the backdrop, the selection of façade materials would be compatible with the surrounding natural elements.  These would help to reduce the visual impacts of the vent shaft structures.

(f)    The TCE Station would be an above-ground structure of approximate height of about 20m along with the at-grade tracks of TCL. The concourse slab level facing the hillside and the skylight of the roof at the TCE Station would adopt transparent glass panels. In order to integrate skylights into the roof, the air-conditioning duct work would be relocated below the concourse slab level. These design features would allow natural light to penetrate into the concourse and help to reduce the associated visual impacts.

(g)   There are 2 pedestrian links connecting the TCE Station and Area 113 of the planned TCNTE (East) development.   Each of these 2 pedestrian links has an approximately length of about 60m and a height of approximately 15m.  In order to mitigate the visual impacts, glass panels will be adopted along the walls of these 2 pedestrian links.  Similar to the case for station entrances in TCW Station, this design feature will alleviate the bulk of the structure and allow natural light to penetrate into the pedestrian links and would help to reduce the associated visual impacts.

·         OM5 Implement Aesthetic Design on Noise Barrier The visual impact of noise mitigation measures will be mitigated by appropriate detailed design to reduce visual bulkiness and incorporate aesthetically pleasing surface treatments to promote visual amenity, including a suitable combination of transparent and sound absorbent materials, appropriate colour selection of panels and supporting structures, as well as the design of supporting structures to incorporate a high level of quality and aesthetics. A combination of transparent panels and solid panels would lighten the visual impact, and at the same time maintain the attractiveness by using colourful panels.

10.8.2.3        Conceptual plans of the above-ground structures are provided in Appendix 10.4 to illustrate the mitigation measures.  

10.9                    Residual Landscape and Visual Impact upon Mitigation

10.9.1               General

10.9.1.1        The potential residual impacts after the implementation of the proposed mitigation measures as described in Table 10.13 have been identified. The potential significance of residual landscape impacts on LRs and LCAs during operation of the development, completion day 1 and year 10 are provided in Table 10.16 and Table 10.17.

10.9.2               Residual Landscape Impact on Landscape Resources

10.9.2.1        Since majority of LRs will not be in direct conflict with the proposed at-grade structures and temporary work areas, so there would be no landscape impacts to the LRs by this Project in general, except the following LRs.

10.9.2.2        The proposed TCE Station with TCL realignment will be mainly located at LR13a Major Transport Corridor and LR16 Ongoing Reclamation Area. Since the amenity value of these LRs are considered as low, with the implementation of mitigation measures such as landscape reinstatement (CM3), optimization of construction areas (CM6), optimised greening provision on structure (OM2) and landscape integration and screen planting (OM3), the impact would be reduced from slight to insignificant.

10.9.2.3        The proposed EAP/ EEP will be erected at LR3 Plantation. This would generate adverse landscape impacts due to the construction activities and loss of vegetation cover.  After the provision of mitigation measures such as tree preservation (CM1), tree transplanting (CM2), landscape reinstatement (CM3), optimization of construction areas (CM6), compensatory tree planting (OM1), optimised greening provision on structure (OM2) and landscape integration and screen planting (OM3). The landscape impact on LR3 would be reduced from moderate to slight.

10.9.2.4        Construction and operation of TCW Station with its vent shaft structures and station entrances will be in direct conflict with LR5 Agricultural Land and LR15 Urbanised Development. It is anticipated that the vegetation covers within these LRs will be removed due to the construction works. With mitigation measures such as tree preservation (CM1), tree transplanting (CM2), landscape reinstatement (CM3), optimization of construction areas (CM6), compensatory tree planting (OM1), optimised greening provision on structure (OM2) and landscape integration and screen planting (OM3), however these measures are limited in terms of scale/ quantity as compared with the LR5. Hence, the residual landscape impact on LR5 after mitigation would be remained as substantial/ moderate. Furthermore, the proposed TCW station would be compatible with LR15. With the implementation of same mitigation measures as LR5, the landscape impact would be reduced from slight to insignificant.

10.9.2.5        Apart from the construction and operation of the proposed TCW and TCE Station, the vent shaft structures and station entrances a series of temporary works areas and barging point will be located at different LRs such as LR13b Road & Urban Infrastructure, and LR14 Village Type Development. For LR13b, the temporary work areas are likely to generate slight landscape impacts due to the small portion loss in terms of the LR area. The landscape impacts would be minimized from slight to insignificant with the implementation of mitigation measures, such as tree preservation (CM1), tree transplanting (CM2), landscape reinstatement (CM3) and optimization of construction areas (CM6). Besides, the proposed temporary works would be compatible with LR14. With same mitigation measures as above, the landscape impact would be reduced from moderate to slight during construction.

10.9.3               Residual Landscape Impact on Landscape Character Areas

10.9.3.1        Similar to LRs, majority of LCAs would not be caused any landscape impacts given no works of the Project will take place on these LCAs, except the following LCAs.

10.9.3.2        There would be moderate landscape impacts on LCA4 Coastal Upland and Hillside Landscape and LCA10 Urban Peripheral Village and Rural Fringe Landscape due to portion of these LCAs will be overlapped with the proposed stations and EAP/EEP. After the implementation of mitigation measures such as tree preservation (CM1), tree transplanting (CM2), landscape reinstatement (CM3), optimization of construction areas (CM6), compensatory tree planting (OM1), optimised greening provision on structure (OM2) and landscape integration and screen planting (OM3), the landscape impacts would be mitigated to slight during both construction and operational stages.

10.9.3.3        A portion of proposed TCL and TCW alignment will be overlapped with LCA8 Transportation Corridor Landscape and LCA9 Mixed Modern Comprehensive Urban Development Landscape. There would be moderate impact due to the construction works of the alignment. With the implementation of mitigation measures such as landscape reinstatement (CM3) and optimization of construction areas (CM6), the landscape impact would be mitigated to slight during construction stage. Besides, the proposed developments are compatible with the existing landscape character, it is considered the residual impact would be insignificant during operational phases.

10.9.3.4        The installation of proposed TCE Station at LCA7 Reclamation/ Ongoing Major Development Landscape would only cause slight impact on the existing landscape character as the proposed works are fully compatible with the surrounding construction activities on reclamation land. With the implementation of mitigation measures such as landscape reinstatement (CM3), optimization of construction areas (CM6), optimised greening provision on structure (OM2) and landscape integration and screen planting (OM3), only insignificant residual impact would be caused.

10.9.4               Residual Visual Impact upon Mitigation

10.9.4.1        The potential residual impacts after the implementation of the proposed mitigation measures as described in Table 10.13 have been identified. The potential significance of residual visual impacts on VSRs during operation of the development, completion day 1 and year 10 are provided in Table 10.18.

10.9.5               Summary of Residual Impacts on VSRs

10.9.5.1        Photomontages for VSR (Figures 10.10a to Figure 10.10d) have been generated to provide views on the scale and extent of the proposed development. It should be noted that the photomontages intend to demonstrate only the scale and massing of the proposed development and effect of the proposed mitigation measures.  The architectural design finishes or any other related detailed design components are subject to refinement and changes at the detailed design stage.

10.9.5.2        In summary, it is considered the implementation of mitigation measures, in particular screen planting, some greening measures such as green roof and/ or vertical greening, would provide significant enhancement to assist in visually integrating the new project into the existing landscape setting and help to alleviate the appearance of built form.  Hence, majority of residual impacts in Section 10.9.5 could be mitigated to acceptable level after the implementation of the proposed mitigation measures.

10.9.5.3        Moderate adverse impacts would be experience by those medium/ high sensitivity VSRs, such as VSR2 Planned Tung Chung New Town Extension, , VSR10 Tung Chung Crescent, VSR11 Fu Tung Estate, VSR16 Yat Tung Estate, VSR18 Mun Tung Estate, VSR19 Ha Ling Pei Village and VSR21 Future Tung Chung West Promenade. The recommended mitigation measures such as landscape reinstatement (CM3), lighting control (CM4), and erection of screen hoarding (CM5), optimised greening provision on structure (OM2), landscape integration and screening planting (OM3), architectural aesthetic design of built structure (OM4) and Implement Aesthetic Design on Noise Barrier (OM5) would effectively alleviate the visual impacts for these VSRs during construction stages and enhance the visual compatibility with the existing landscape setting during the operational phase. Meanwhile, the future high-rise development at TCNTE would block the view of the proposed TCE Station and the TCL realignment on VSR3 Ying Tung Estate and VSR4 The Visionary. It is considered that visual impact of these VSR could be mitigated together with recommended mitigation measures such as landscape reinstatement (CM3), lighting control (CM4), optimised greening provision on structure (OM2), landscape integration and screening planting (OM3), architectural aesthetic design of built structure (OM4) and Implement Aesthetic Design on Noise Barrier (OM5).  Furthermore, for some of the VSRs that have a distant view toward the small scale of proposed structures, such as VSR5 Caribbean Coast, VSR9 Scenic Hill, and VSR12 Lantau North Country Park. After the implementation of recommended mitigation measures such as landscape reinstatement (CM3), lighting control (CM4), optimised greening provision on structure (OM2), landscape integration and screening planting (OM3), and architectural aesthetic design of built structure (OM4), it is considered the residual impacts would be insignificant during both construction and operational phases.

10.9.5.4        It is considered that slight visual impacts would remain at slight/insignificant level during construction stage for low sensitivity VSRs such as VSR1 North Lantau Highway and VSR15 Yu Tung Road and VSR22 Tung Chung Line & Airport Express Line. With the mitigation measures such as landscape reinstatement (CM3), lighting control (CM4), and erection of screen hoarding (CM5), optimised greening provision on structure (OM2), landscape integration and screening planting (OM3), and architectural aesthetic design of built structure (OM4). These VSRs would remain as insignificant level during operational stage.

10.9.5.5        Apart from the construction and operation of the proposed at-grade structures, a series of scattered temporary works areas and barging point would also generate small to moderate impermanent visual impacts before operation, such as VSR6 Sheraton Hong Kong Tung Chung Hotel, VSR7 Coastal Skyline, VSR8 Chek Lap Kok Airport Island, VSR13 Yu Tai Court, and VSR14 Ma Wan New Village. The residual impacts would be mitigated to slight/ insignificant levels after the implementation of the construction mitigations, such as lighting control (CM4) during construction stage.

Approximately 290 number of trees along Yu Tung Road will need to be fell due to the demolition and reprovision of footbridge across Yu Tung Road. 

Other than these trees, no valuable landscapes are currently present on the urbanised area, adverse landscape impact during both construction and operational phases is not anticipated.

Visual

Given the proposed works are compatible with the Project, it is anticipated that the cumulative visual impact would not be significant.

The respective project proponent will fulfil all the  requirements for tree transplanting and landscape enhancement.  On this basis, adverse cumulative landscape impacts are not anticipated 

It is anticipated that the design of the new footbridge will incorporate suitable aesthetic design to blend in with the environment.  No visual impacts are therefore identified in construction stage.

No additional landscape and visual impacts are identified during operation.

No natural landscape resources, or rare or protected species are recorded within SHD according to their approved EIA Report.  Hence, adverse cumulative landscape impact during both construction and operational phases is not anticipated.

Visual

The SHD is located at more than 1km from the TCE Station and 5km from TCW Station.  Given the large separation distance from TCE Station and TCW Station, it is anticipated that the SHO and reprovisioned SHD would not cause any substantial cumulative visual impact on adjacent VSRs

No significant cumulative landscape and visual impacts are identified in construction stage.

No significant cumulative landscape and visual impacts are identified during operation.

Proposed Comprehensive Residential and Commercial Development atop Siu Ho Wan Depot

10.11              Conclusion

10.11.1.1   The majority extent of the development is compatible with the surrounding local context, the project would generate insignificant to moderate/substantial adverse visual impact during construction phase and insignificant to moderate adverse visual impact during operational phase without the provision of mitigation measures.

10.11.1.2   With the provision of mitigation measures, most of the residual landscape impacts would be insignificant to slight by operation year 10. The likely residual visual impacts and possibility would be insignificant to slight by operation day 1 and operation year 10 when the mitigation measures have matured and taken effect. It is therefore anticipated that the overall residual landscape and visual impacts from the proposed scheme of Tung Chung Line Extension are considered acceptable with mitigation measures.
