8.            Landscape and Visual Impact Assessment

8.1         Introduction

8.1.1     This section presents the landscape and visual impact assessment (LVIA) for the construction and operation of the Project to outline and examine the landscape baseline conditions of existing landscape resources (LRs) and the landscape character areas (LCAs), the visual amenity, visually sensitive receivers (VSRs), and the planning and development control frameworks within the assessment area where Chapter 3 shows the project details.  The assessment area includes all areas within 500m from the Project boundary, while the study area for the visual impact assessment is defined by the Visual Envelope of the Project (i.e. a zone of visual influence which should include all areas from which the proposed scheme of the Project can be seen).  The assessment includes:

·           A definition of the scope and contents of the proposed works;

·           A review of relevant planning and development control framework;

·           A baseline study providing a comprehensive and accurate description of the baseline landscape resources, landscape character areas and visual sensitive receivers (VSRs);

·           Identification of the potential landscape and visual impacts and prediction of their magnitude and potential significance, before and after the mitigation measures;

·           Recommendations for appropriate mitigation measures; and

·           An assessment of the acceptability or the predicted residual impacts, according to Annex 10 of the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM).

8.1.2     The landscape and visual impact assessment follows the criteria and guidelines as stated in Annexes 10 and 18 of the EIAO-TM.  Illustrative materials supporting conclusions are provided and the locations of all key viewpoints have been clearly mapped.  Photomontages at representative locations provide a comparison between existing views, proposals on day 1 after completion without and with mitigation measures, and in year 10 after completion with mitigation measures in accordance with EIAO Guidance Note No. 8/2010.

8.2         Environmental Legislation and Guidelines

8.2.1     The assessment has been conducted in accordance with the following:

·           Environmental Impact Assessment Ordinance (EIAO) (Cap. 499);

·           EIAO-TM, particularly Annex 10 “Criteria for Evaluating Visual and Landscape Impact” and Annex 18 “Guidelines for Landscape and Visual Impact Assessment”;

·           Environmental Impact Assessment Ordinance Guidance Note No. 8/2010 “Preparation of Landscape and Visual Impact Assessment under the Environmental Impact Assessment Ordinance”;

·           Town Planning Ordinance (Cap. 131);

·           Hong Kong Planning Standards and Guidelines Chapters 4 Recreation, Open Space and Greening, and Chapters 11 Urban Design Guidelines;

·           WBTC No. 7/2002 Tree Planting in Public Works;

·           WBTC No. 3/2006 Tree Preservation;

·           WBTC No. 29/2004 Registration of Old And Valuable Trees and the guidelines for Preservation;

·           WBTC No. 2/2004 Maintenance of Vegetation and Hard Landscape Features;

·           WBTC No. 25/92 Allocation of Space for Urban Street Trees;

·           Study on Landscape Value Mapping of Hong Kong;

·           Southwest Kowloon Outline Zoning Plan (OZP) No. S/K20/28;

·           Animals and Plants (Protection of Endangered Species) Ordinance (Cap. 187); and

·           WBTC No. 14/2002 Management and Maintenance of Natural Vegetation and Landscape Works and Tree Preservation.

8.3         Planning and Development Control Framework

8.3.1     The Site is situated in urban area in Cheung Sha Wan.  The Site falls within an area zoned as “Government, Institution or Community (GIC)” on the latest South West Kowloon Outline Zoning Plan (OZP) No. S/K20/28 and designated as “Government” and “Cable / Drainage / WSD / MTRC Reserve” on the draft South West Kowloon (Central Section) Outline Development Plan (ODP) No. D/K20B/D.  According to the Notes of the OZP, the planning intention of the zone is intended to “provide Government, institution and community facilities serving the needs of the local residents and/or a wider district, region or the territory.  It is also intended to provide land for users directly related to or in support of the work of the Government, organizations providing social services to meet community needs, and other institutional establishments”.  The current proposed Depot is fulfilling the planning intention.

8.3.2     While there is no building height or plot ratio restrictions stipulated on the OZP for the subject site, the West Kowloon Reclamation Review Study recommended building height and plot ratio restrictions of 30 metres above Hong Kong Principal Datum (mPD) and 2.5 respectively. In order to address site constraints and operational needs, these restrictions would be slightly relaxed to 35.4 mPD and 3.75 accordingly.

8.4         Assessment Methodology

Landscape Baseline Review and Impact Assessment

8.4.1     The study area for the landscape impact assessment shall include all areas within 500 metres distance from the boundary of the Site.  The study area for the visual impact assessment shall be defined by the visual envelope of the Site, i.e. zone of visual inference of the proposed Depot.

Identification of Landscape Resources and Landscape Character Areas

8.4.2     The Baseline Study was conducted based on desktop study and field surveys to identify and examine existing Landscape Resources / Characters Types within the Landscape Assessment Study Area and Visual Resources within the Visual Assessment Study Area.

8.4.3     Landscape Resources (LRs) refer to the basic landscape elements such as topography, natural landscape form and patterns of settlement of built features, land use, streetscapes, and any cultural, historical and/or religious identity.  A tree survey has been conducted within the Project site and its immediately adjacent areas, in order to identify the landscape resources and quality with respect to the tree species characters, ecological/conservation value, health and structural conditions of the existing trees of the Site.

8.4.4     Landscape Character Areas (LCAs) refer to a broad homogenous units derived from the presence and combination of similar landscape characters within the study area have been mapped and annotated on a plan.

Methodology of Landscape Impact Assessment

8.4.5     Potential impacts arisen by the proposed Depot were assessed for both construction and operation stages.  The impact assessments allow predictions to be made about the likely levels and significance of landscape impacts.  The assessment of landscape impacts will result from:

·           the landscape character and its quality;

·           the sensitivity of the landscape in accommodating change;

·           source, nature and magnitude of impacts;

·           the degree of change caused by the impacts to the existing landscape;

·           significance of the change in consideration of the local and regional areas and other developments;

·           cumulative effects with other proposals; and

·           identification of vegetation of significant value which should be conserved.

8.4.6     The sensitivity/quality for landscape characters/resources would normally be based on:

·           quality of landscape characters/resources;

·           ability of the landscape to accommodate change;

·           importance and rarity of special landscape elements;

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

·           maturity of the landscape.

8.4.7     The sensitivity/quality of the landscape character/resources will be assessed as follows:

·           High: important components or landscape of particularly distinctive character susceptible to small changes;

·           Medium: a landscape of moderately valued characteristics reasonably tolerant to change; and

·           Low: a relatively unimportant landscape, which is able to accommodate extensive change.

8.4.8     The magnitude of change to landscape characters/resources would normally be assessed by considering:

·           compatibility of the proposed project with the surrounding landscape;

·           duration of impacts in construction and  operation phase;

·           scale of development, and

·           reversibility of change.

8.4.9     The magnitude of change to landscape character/resources would be classified as follows:

·           Large: notable change in the landscape characteristics over an extensive area ranging to very intensive change over a more limited area;

·           Intermediate:  moderate changes to a local area;

·           Small: changes to components; and

·           Negligible:  no perceptible changes.

8.4.10   The system for the assessment of the overall landscape impact is summarized in Table 8‑1 below.  The significant threshold of landscape impact is derived from the combined analysis of the magnitude of change and the landscape’s quality and sensitivity.  The matrix in Table 8‑1 indicates how the impact is derived.

Notes:

Significant:    Adverse / beneficial impact where the proposed depot-cum-office building would cause significant degradation or improvement in existing landscape baseline conditions.

Moderate:      Adverse / beneficial impact where the proposed depot-cum-office building would cause noticeable degradation or improvement in existing landscape baseline conditions.

Slight:             Adverse / beneficial impact where the proposed depot-cum-office building would cause a barely noticeable degradation or improvement in existing landscape conditions or where the changes brought about by the proposed depot would not be apparent in visual terms.

Negligible:     The proposed depot-cum-office building does not perceptibly affect the existing landscape baseline conditions.

 

Methodology of Visual Impact Assessment

8.4.11   The visual impact assessment identifies the types and extent of visual impacts arising from the implementation of the proposed Depot, with respect to:

·           visual compatibility with the surroundings;

·           their imposition of possible visual obstruction to neighbouring visual amenity; and

·           possible improvement of visual quality.

8.4.12   The assessment of potential visual impacts will result from:

·           the sensitivity of the viewer groups at VSR locations to change and visual intrusion; and

·           the magnitude of change to the visual baseline condition.

8.4.13   The sensitivity of receivers is normally based on:

·           value and quality of existing views;

·           availability and amenity alternative views;

·           type and estimated number of receiver population;

·           duration or frequency of view; and

·           degree of visibility.

8.4.14   Using the criteria above, the sensitivity of VSRs locations will be classified as follows:

·           High: VSRs are highly sensitive to changes in their viewing experience

·           Medium: VSRs are moderately sensitive to change in their viewing experience

·           Low: VSRs are slightly sensitive to changes in their viewing experience

8.4.15   The assessment of the magnitude of change to VSR is normally based on:

·           compatibility of the proposed depot-cum-office building with the surrounding landscape;

·           duration of impacts under construction and operation phases;

·           scale of development;

·           reversibility of change;

·           viewing distance; and

·           potential blockage of view.

8.4.16   Research has shown that an object or development will dominate human vision mainly depending on the amount of space occupied within the horizontal field of view of the human eye.  In general, objects which occupy greater than approximately 30 degrees of the field of view are considered to be visually intrusive.  Using this criterion, the magnitude of change to visual resources would be classified as follows:

·           Large: There would be major changes in view to the VSRs

·           Intermediate: There would be moderate changes in view to VSRs

·           Small: There would be minor changes in view to VSRs

·           Negligible: There would be no discernible changes in view to VSRs

8.4.17   The significant threshold of visual impact is rated in a similar fashion to the landscape impact and is illustrated in Table 8‑2 below.

Negligible:     The proposed depot-cum-office building does not perceptibly affect the existing visual baseline conditions.

 

Residual Landscape and Visual Impacts

8.4.18   The final stage of the LVIA study is to assess the significance of the residual impacts of the study assuming landscape mitigation measures are incorporated into the design.  In conclusion the landscape and visual impacts are then classified into one of five levels of significance. (This classification is made with reference to the criteria in Annex 10 of the EIAO-TM), as summarised below:

·           the impact is beneficial if the proposed depot-cum-office building will complement the landscape and visual character of its setting, will follow the relevant planning objectives, and will improve the overall and visual quality of the Study Area;

·           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 proposed depot-cum-office building, or no interference with key views;

·           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;

·           the impact is unacceptable if  the adverse effects are considered too excessive and are unable to be mitigated practically; or

·           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.

Photomontages

8.4.19   The visual impacts and effectiveness of the proposed mitigation measures as stated in Section 8.8 are demonstrated using photomontages to illustrate existing views and future views (Day 1 to Year 10) of the Project operation from key groups of VSRs to illustrate existing conditions and operational stage conditions in relation to other existing and planned developments and prominent visual features.  Three viewpoints have been selected for preparing the photomontages, as described below:

·           Viewpoint 1 (VP 1): on Yen Ming Road West immediately outside Nam Cheong Station Exit facing to the Site, representing a location from which the Site is most visible to the travelers (refer to Figure 8-11 and Section 8.5.45). The VSRs may experience glimpse to full views of the Site when they are travelling along.

·           Viewpoint 2 (VP 2): at various levels of Metro Harbour View, representing views from the residents located opposite to the Site (refer to Figure 8-9 and Section 8.5.34), The VSRs may have distant and glimpse to partial view of the Site at medium to high level, but Nam Cheong Park and the harbor area will feature more prominently in their views due to the small scale of the Site.

·           Viewpoint 3 (VP 3): at various levels of Hampton Place, representing views from the residents located closest to the Site (refer to Figure 8-10 and Section 8.5.39). These VSRs may have closer partial to full view of the Site at level, while the view of medium level will be significantly blocked by Tai Kok Tsui Catholic Secondary School (Hoi Fan Road) and CLPP Tai Kok Tsui Substation (TKT S/S).

 

8.5         Baseline Study

Baseline Landscape Study

8.5.1     Based on desktop studies and site visits, Landscape Resources (LRs) and Landscape Character Areas (LCAs) within 500m from the site boundary have been identified.  Figure 8-1 and Appendix 8-1 display the extent of various types of existing landscape resources within the study area. Photos of some key landscape resources will be shown in Appendix 8-2.

Existing Landscape Resources (LRs)

LR 1 Open Space

8.5.2     LR 1 refers to Open Space covering public parks / public rest garden, playgrounds, sport grounds and sitting-out areas within the study area.

·           LR 1-1 Nam Cheong Park: a public park in urban area of Sham Shui Po, managed by Leisure and Cultural Services Department (LCSD).  It is about 45,000m2 in size, consisting of play equipment for toddlers and fitness equipment for children and elderly.  The park is well-vegetated and dominated by the large grass/lawn and massive planting at the northern entrance. Dominant species include, Bauhinia blakeana (洋紫荊), Archontophoenix alexandrae (假檳榔), Ficus microcarpa (細葉榕), Peltophorum pterocarpum (雙翼豆), Pongamia pinnata (水黃皮), Grevillea robusta (銀樺), Cassia fistula (豬腸豆), Ficus religiosa (菩提樹) and Litsea glutinosa( 潺槁樹). Besides Bauhinia blakeana, Pongamia pinnata, Litsea glutinosa and Ficus microcarpa, all species are exotic, except Bauhinia blakeana.  It is considered of high public amenity value and high sensitivity.

·           LR 1-2 Tung Chow Street Park: a public park in urban area of Sham Shui Po, managed by LCSD.  It is 38,000m2 in size, consisting of artificial lake, pavilions and square, soccer pitches, basketball courts, volleyball courts and tennis courts.  Dominant species include Delonix regia (鳳凰木) and Ficus microcarpa (細葉榕), Cinnamomum burmannii (陰香), Plumeria rubra L. (雞蛋花), Callistemon viminalis (串錢柳), Lagerstroemia speciosa (大花紫薇), Bischofia polycarpa (重陽木) and Araucaria cunninghamii (南洋杉). Besides Ficus microcarpa and Cinnamomum burmannii, all species are exotic.  The park is well vegetated and considered of medium amenity value and medium sensitivity.

·           LR 1-3 Chui Yu Road Rest Garden: a vegetated rest garden nearby Metro Harbour View.  It is about 4,000m2 in size. Dominant species include Ficus benjamina (垂葉榕), Ficus microcarpa (細葉榕), Lagerstroemia speciosa (大花紫薇), Plumeria acutifolia (雞蛋花), Senna surattensis (黃槐) and Bauhinia blakeana (洋紫荊). Besides Ficus microcarpa and Bauhinia blakeana, all species are exotic. The garden is considered of medium amenity value and low sensitivity.

·           LR 1-4 Fu Cheong Estate Playground and Basketball Courts: the playground provides play equipment for children and the basketball courts provides places basketball game for residents of Fu Cheong Estate.  The LR is considered of low amenity value and low sensitivity.

·           LR 1-5 Olympian City Promenade Park: a vegetated rest garden nearby Olympian City One. It is about 5,000m2 in size. Dominant species include Ficus microcarpa (細葉榕), Plumeria acutifolia (雞蛋花), Acacia confusa (台灣相思), Mascarena lagenicaulis (酒瓶椰子) and Bombax ceiba (木棉). Amongst these species, only Ficus microcarpa are native species. The LR is considered of medium value and sensitivity.

LR 2 Roadside Planting

8.5.3     LR 2 refers to all the roadside planting areas within the study area.  The landscape composition and conditions of the subdivisions are similar, where Leucaena leucocephala (銀合歡), Melaleuca leucadendron (白千層), Archontophoenix alexandrae (假檳榔), Peltophorum pterocarpum (雙翼豆), Melia azedarach (苦楝), Delonix regia (鳳凰木), Ficus microcarpa (細葉榕) and Aleurites moluccana (石栗) as well as some shrub species such as Codiaeum variegatum (L.) A. Juss (灑金榕), Tradescantia spathacea (蚌花) and Asparagus cochinchinensis (天冬) are the dominant species, which are all exotic species, except Ficus microcarpa, and Leucaena leucocephala is invasive. The tree species found are all with young to semi-mature age and in generally fair to good health conditions due to regular maintenance.  The development of proposed Depot will not cause any disturbance to LR2.  LR 2 includes the followings:

·           LR 2-1 Along Lin Cheong Road;

·           LR 2-2 Not Used

·           LR 2-3 Along Hoi Fan Road;

·           LR 2-4 Along Hoi Fai Road;

·           LR 2-5 Along Sam Mong Road;

·           LR 2-6 Along Chui Yu Road;

·           LR 2-7 Along Sai Chuen Road;

·           LR 2-8 Along Yen Chow Street West;

·           LR 2-9 Along Tonkin Street West; and

·           LR 2-10 At the T-Junction of Yen Chow Street West and Lin Cheong Road amid Fu Cheong Estate and Nam Cheong Estate.

8.5.4     These roadside plantings apparently provide greenery to soften the urban environment. This LR is considered of medium amenity value and low sensitivity.

LR 3 Marine Frontage (Water Bodies)

8.5.5     LR 3 refers to sea area annexed to Stonecutters Island and bounded by reclaimed land adjoining Cheung Sha Wan Wholesale Fish Market, Yuen Fat Building and cargo area at Yen Chow Street West, Hong Kong Marine Police Operation Base, Hampton Place and the Long Beach at Hoi Fan Road.  It includes:

·           LR 3-1 Cargo Handling Basin; and

·           LR 3-2 Waterfront Promenade

8.5.6     For LR 3-1, since the coastline has been straightened to form the cargo handling area. Despite that the basin area belongs to natural resources and cannot be re-created, it has already utilized and heavily trafficked by container ships, LR 3-1 is therefore considered to be of low public amenity value and low sensitivity.

8.5.7     On the contrary, LR 3-2 is a portion of the sea frontage near the Long Beach. It forms a water front promenade and provides attractive waterfront for residents. This LR is considered as high amenity value and sensitivity.

LR 4 Vacant Land

8.5.8     LR 4 refers to the unused vacant lands in the study area, including:

·           LR 4-1 To the northwest of Wholesale Fish Market along Lin Cheong Road, bounded by Lin Cheong Road and the marine frontage;

·           LR 4-2 Bounded by Sir Ellis Kadoorie Secondary School (West Kowloon) and Lin Cheung Road;

·           LR 4-3 Bounded by Sham Mong Road and Lin Cheung Road, inside Nam Cheong Park, as a current construction site of MTR Express Rail Line (XRL); and

·           LR 4-4 Adjacent to Nam Cheong MTR Station, which is currently occupied as MTR Express Rail Line (XRL) construction work site.

8.5.9     LR 4 consists of human created areas without or lacking vegetation, that is not yet occupied or used as temporary construction work sites.  It is considered of low amenity value and low sensitivity compared to the vegetated area.

LR 5 Vacant Land / Slope Vegetation

8.5.10   Unlike LR 4, LR 5 refers to the spontaneously or naturally established vegetation of disturbed area within the unused vacant lands.  The plants found here are believed to be highly tolerant to environmental stresses within the degraded urban landscape.  They can be regenerated easily under undesirable environment, such as lack of soil and moisture.  LR 5 includes:

·           LR 5-1 Immediately in front of the exit of Nam Cheong Station to the northeast of the Site;

·           LR 5-2 Behind Nam Cheong Station Exit, along Wholesale Market Street, to the northwest of the Site;

·           LR 5-3 At the northeastern periphery of the site bounded by the Site itself and CLP Tai Kok Tsui Substation;

·           LR 5-4 At the northwestern periphery of Wholesale Fish Market;

·           LR 5-5 In between the vacant land to the northeast of Sir Ellis Kadoorie Secondary School (West Kowloon);

·           LR 5-6 Bounded by Hoi Fan Road and Lin Cheong Road, adjacent to Tai Kok Tsui Catholic Primary School (Hoi Fan Road);

·           LR 5-7 At the slope next to bus terminal at Tonkit Street West; and

·           LR 5-8 To the north of Sewage Screening Plants of Drainage Service Department (DSD).

8.5.11   Some of the LRs, such as LR 5-5, LR 5-6 and LR 5-8 cannot be accessed during the site visits as the areas were locked. However, as seen from the outside and upon site observations of LR 5-1, LR 5-2, LR 5-3, LR 5-4 and LR 5-7, much of the vegetation of LR 5 belongs to weedy vegetation, such as Lantana camara (馬纓丹), Bidens alba (白花鬼針草), Oxalis corniculata L. (酢醬草), Wedelia chinensis (蟛蜞菊), Rhynchelytrum repens (紅毛草), or some common exotic species includes  Leucaena leucocephala (銀合歡), Acacia auriculiformis (耳果相思), Brassaia actinophylla  (澳洲鴨腳木), Aglaia odorata (米仔蘭), Bombax ceiba (木棉). The vegetation apparently provides some greenery to the densely-built areas.  The development of the proposed Depot will not cause any disturbance to LR 5, except LR 5-3 where some of the trees may be felled, which will be discussed in Section 8.6). Considering the exotic nature of the vegetation, the amenity value and sensitivity of LR 5 are of low amenity value and low sensitivity.

LR 6 Residential / Amenity Planting

8.5.12          LR 6 refers to the architectural landscape planting area within residential developments or open area of the study area.  These landscape plantings are dominated by mainly common exotics tree species of young to semi-mature age, and generally in fair to good health conditions due to regular maintenance.  LR 6 includes the following:

·           LR 6-1 At Fu Cheong Estate;

·           LR 6-2 At Nam Cheong Estate;

·           LR 6-3 At Sewage Screening Plants of DSD;

·           LR 6-4 Between Hampton Place and the Long Beach;

·           LR 6-5 At the Long Beach;

·           LR 6-6 At Island Harbourview;

·           LR 6-7 At Olympian City One

·           LR 6-8 At Harbour Green;

·           LR 6-9 Metro Harbour View;

·           LR 6-10 To the southwest of Sewage Screening Plant of DSD amid Fu Cheong Estate and Nam Cheong Estate;

·           LR 6-11 Along the Waterfront Promenade adjacent to the Long Beach; and

·           LR 6-12 Adjacent to Exit C of Nam Cheong MTR Station.

8.5.13   While some of the LRs are planted at Sewage Screening Plants of DSD (LR 6-3) and in the podium of the residential development, such as the Long Beach (LR 6-5), Island Harbourview (LR 6-6), Olympian City One (LR 6-7), Harbour Green (LR 6-8) and Metro Harbour View (LR 6-9), requires security check and merely allow talents accessing, the species could not be identified during the course of site visit. Other LRs located at Fu Cheong Estate (LR 6-1), Nam Cheong Estate (LR 6-2), between Hampton Place and the Long Beach (LR 6-4), to the southwest of Sewage Screening Plant of DSD amid Fu Cheong Estate (LR 6-10) and Nam Cheong Estate, along the Waterfront Promenade adjacent to the Long Beach (LR 6-11) and adjacent to Exit C of Nam Cheong MTR Station (LR 6-12) offer well-vegetated or architectural designed area adjoining the leisure or recreational ground / facilities of the residential developments, and help soften the hard and dull densely built-up area such as roads and residential buildings. Dominant species includes Bauhinia blakeana (洋紫荊), Phoenix roebelenii (日本葵), Garcinia subelliptica (福木), Peltophorum pterocarpum (雙翼豆), Plumeria acutifolia (雞蛋花), Ficus microcarpa (細葉榕), Delonix regia (鳳凰木), Kaya senegaensis (Desr.) A.Juss (非洲棟), Bombax ceiba (木棉), Grevillea robusta (銀樺), etc. Only Ficus microcarpa and Bauhinia blakeana are native species. These LRs are considered of high amenity value and high sensitivity.

8.5.14   Sensitivity of the existing landscape resources are listed in Table 8-3.

Landscape Resources (LRs) with Planned Development

8.5.15   In view of the proposed comprehensive residential and commercial development above Nam Cheong Station, as well as the planned football pitch and basketball court at adjacent to Tai Kok Tsui Catholic Primary School (Hoi Fan Road), categories of landscape resources of “Vacant Land Vegetation” of LR 5-6 and LR 5-7 will be changed to “Open Space” and “Residential / Amenity Planting” respectively.  Figure 8-2 displays the extent of various types of landscape resources with planned developments within the study area.  The changes of LR are summarised in Table 8‑4.

8.5.16   Based on the available information, the proposed comprehensive residential and commercial development above Nam Cheong Station will be established in the year of 2017 to 2019 by phase, and there is no construction programme of the football pitch and basketball court at Hoi Fan Road during the course of report, while the proposed Depot will be constructed in 2014 and in operation in 2017.  Therefore, the sensitivity of LR 1-P1 and LR 6-P1 is not applicable and will be remarked as “NA”.

Existing Landscape Character Areas (LCAs)

8.5.17   A total of six landscape character areas (LCAs) formed by various broadly homogenous units of similar landscape characters were identified within the 500m study area, as shown in Figure 8-3 and Appendix 8-3.  These areas include:

LCA 1 Marine Frontage Landscape

8.5.18   LCA 1 refers to the marine frontage landscape consisting of cargo handling basin (water bodies), the wharf bound by Yen Ming Road and the waterfront promenade (water bodies). It is characterised predominantly by the sea area occupied by container ships and cargos without vegetation found inside. Despite the water bodies of cargo handling basin belongs to natural resources and cannot be re-created, it is already mainly utilized and heavily trafficked, which is of low quality and amenity value, and thus low sensitivity. However, due to the higher quality and high amenity value and thus high sensitivity of the waterfront promenade, the whole LCA is considered to have medium overall amenity value and medium sensitivity.

LCA 2 Wholesale Food and Fish Market Landscape

8.5.19   LCA 2 refers to Wholesale Food and Fish Market Landscape, comprising Cheung Sha Wan Wholesale Food Market Office and Fish Market Office operated by Agricultural, Fisheries and Conservation Department (AFCD), haul road and carpark. Being situated in the urban area bounded by Yen Ming Road and Wholesale Market Street with no vegetation located within the area and mainly utilized as wholesaling activities with low quality, it is considered to have low amenity value and low sensitivity.

LCA 3 Park Landscape

8.5.20   LCA 3 is mainly consisted of Nam Cheong Park and Tung Chau Street Park. It is dominated by well-vegetated plants, including, Bauhinia blakeana (洋紫荊), Archontophoenix alexandrae (假檳榔), Ficus microcarpa (細葉榕), Peltophorum pterocarpum (雙翼豆), Pongamia pinnata (水黃皮), Grevillea robusta (銀樺), Cassia fistula (豬腸豆), Ficus religiosa (菩提樹) and Litsea glutinosa (潺槁樹). Besides Bauhinia blakeana, Pongamia pinnata, Litsea glutinosa and Ficus microcarpa, all species are exotic, except Bauhinia blakeana, as mentioned in Section 8.5.2, of high amenity value and in fairly good health / physical conditions due to regular maintenance. They are of high quality and high maturity. Since they are common species, the importance / rarity of special landscape elements is low. Although LCA 3 comprised primarily man-made landscape features, it is considered to have a high sensitivity.

LCA 4  Open Car Parks / Vacant Land Landscape

8.5.21   LCA 4 refers to vacant land including uncovered car parks along Lin Cheong Road, vacant land along Yen Ming Road (the Site itself), construction sites at Nam Cheong Station and Nam Cheong Park, and vacant lands along Hoi Fan Road and Tung Chow Street.  Due to the fact that this LCA is situated at urban area, which are commonly found amongst the territory, and this LCA is lacking vegetation or the vegetation is weedy, such as Lantana camara (馬纓丹), Bidens alba (白花鬼針草), Oxalis corniculata L. (酢醬草), Wedelia chinensis (蟛蜞菊), Rhynchelytrum repens (紅毛草), the quality and amenity value is low, it is considered as low sensitivity.

LCA 5  Community / Residential Urban Landscape

8.5.22   LCA 5 refers to the built up and densely populated area in Cheung Sha Wan District dominated by high-rise residential buildings, and medium to high rise buildings of community services such as schools, flyovers and roads trafficked by vehicles, as well as the rest garden and sitting-out areas.  It is considered as the largest LCA within the study area and is one of the most common landscape characters within the territory. Dominant species includes Bauhinia blakeana (洋紫荊), Phoenix roebelenii (日本葵), Garcinia subelliptica (福木), Peltophorum pterocarpum (雙翼豆), Plumeria acutifolia (雞蛋花), Ficus microcarpa (細葉榕), Delonix regia (鳳凰木), Khaya senegalensis (Desr.) A.Juss (非洲棟), Bombax ceiba (木棉), Grevillea robusta (銀樺), etc. Although the landscape quality is good because of regular maintenance and maturity is low moderate, the species are common and thus the importance / rarity of landscape element is low, As a result, it is considered to be of low amenity value and low sensitivity.

LCA 6 Public Services Landscape

8.5.23   LCA 6 refers to buildings or facilities providing services to the public, such as Nam Cheong Station operated by MTR Corporations, West Kowloon Central Sewage Pumping Station and Sewage Treatment Screening Plant operated by DSD, Hong Kong Marine Police Operation Base operated by Police Force, and Tai Kok Tsui Substation and Traction Sub-station operated by CLP Power Ltd.  Since they are lacking vegetation and thus of low quality, and this character type is commonly found amongst the territory, they are considered as low amenity value and low sensitivity.

8.5.24   The sensitivity of the existing landscape character areas are listed in Table 8‑5.

Existing Trees within the Proposed Site

8.5.27   A total of 16 tree specimens were identified within the project site boundary as included in Appendix 8-4.  15 nos. (93.8%) of the surveyed trees belong to the invasive exotic species Leucaena leucocephala (銀合歡) while 1 no. (6.2%) of non-native species is Bombax ceiba (木棉).  Out of16 trees, 4 trees (25%) were found to have poor tree form but generally in fair health condition and 12 trees (75%) were found in generally fair health and tree form.  No registered or potential Old and Valuable Trees (OVTs) were recorded nor rare or protected species were encountered.  Detailed information of the surveyed trees is presented in the Tree Assessment Schedule in Appendix 8-4.  Table 8‑7 summarises the tree species composition within the Site.

8.5.30   The selected VSRs are representative of views available to viewers at each of the above locations.

8.5.31   Figure 8-7 shows the locations of the identified VSRs as described as follows:

VSR R01 Residents of Fu Loy House, Fu Ying House and Fu Yuet House of Fu Cheong Estate

8.5.32   These VSRs may have a distant view of the Site at medium to high level, while their view of the Site will be significantly blocked by existing Nam Cheong Station and West Kowloon Highway.  Due to small scale of the proposed development, views of Nam Cheong Park or more distant view of the harbour area, which are considered to have much higher amenity value compared to that of the Site, will feature much more prominently in the visual envelop for residents within these estates. Therefore, the sensitivity of these VSRs is considered to be low.

VSR R02 Residents of Cheong Chit House and Cheong Yat House of Nam Cheong Estate

8.5.33   Similar to VSR R01, these VSRs may have a distant partial view of the Site at high level, while the view at the medium level will be significantly blocked by existing trees of Nam Cheong Park and those along Sam Mong Road, and West Kowloon Highway. The sensitivity of these VSRs is considered to be low.

VSR R03 Residents of Blocks 1 and 2 of Metro Harbour View

8.5.34   These VSRs may have a distant, but closer when compared with VSR R01 and R02, and glimpse to partial view of the Site at medium to high level.  Due to the small scale of the Site, and Nam Cheong Park and the harbour area, which are considered to have much higher amenity value, will feature more prominently in their views. The sensitivity of these VSRs is considered to be low.  Figure 8-9 displays the existing views and the photomontages showing the views of the Site from various levels of Block 1 of Metro Harbour (Viewpoint 2).

VSR R04 Residents of West Kowloon Disciplined Services Quarters

8.5.35   Sitting next to Metro Harbour View, these VSRs have similar views of VSR R03, which may have a glimpse to partial view of the Site at medium to high level.  Due to the small scale of the Site, and Nam Cheong Park and the harbour area, which are considered to have much higher amenity value will feature more prominently in their views. The sensitivity of these VSRs is considered to be low.

VSR R05 Residents of Blocks 1, 3, 4 and 5 of Harbour Green

8.5.36   These VSRs may have glimpse to partial view of the Site at medium to high level.  Also, Nam Cheong Park and other streetscapes in the vicinity, which are considered to have much higher amenity value, will feature more prominently in their views.  The sensitivity of these VSRs is considered to be low.

VSR R06 Residents of Block 1 of Island Harbourview

8.5.37   These VSRs may have closer glimpse to partial of the Site at high level, while the view of medium level will be significantly blocked by Tai Kok Tsui Catholic Secondary School (Hoi Fan Road).  Due to the small scale of the Site, the harbour area and other streetscapes in the vicinity, which are considered to have much higher amenity value, will feature more prominently in their views.  The sensitivity of these VSRs is considered to be low.

VSR R07 Residents of Blocks 8 and 9 of The Long Beach

8.5.38   The Long Beach is located nearby Island Harbourview.  Similar to VSR R06, these VSRs may have closer glimpse to partial view of the Site at high level, while the view of medium level will be significantly blocked by Tai Kok Tsui Catholic Secondary School (Hoi Fan Road) and CLP Tai Kok Tsui Substation.  The sensitivity of these VSRs is considered to be low.

VSR R08 Residents of Blocks 1, 2 and 3 of Hampton Place

8.5.39   The Hampton Place is located nearby The Long Beach.  Similar to VSR R07, these VSRs may have closer partial to full view of the Site at high level, while the view of medium level will be significantly blocked by Tai Kok Tsui Catholic Secondary School (Hoi Fan Road) and CLPP Tai Kok Tsui Substation (TKT S/S).  The sensitivity of these VSRs is considered to be low.  Figure 8-10 displays the existing views and the photomontages showing the views of the Site from various levels of Block 1 of Hampton Place (Viewpoint 3).

VSR W01 Staff of Wholesale Market Office

8.5.40   These VSRs are the occupational receivers to the west of the Site.  Since the Wholesale Market Office is a low-rise building, the views are blocked by existing fencing of the wholesale market area and settlements.  Since the quality of existing view is poor, the number of staff of wholesales market office is few and their frequency of view is intermittent, the sensitivity of these VSRs is considered to be low.

VSR W02 Staff of Yuen Fat Building and Cargo Unloading / Loading Area

8.5.41   Yuen Fat Building and the cargo unloading / loading area are located immediately opposite to the Site.  These VSRs are also occupational receivers and may have a close full view of the Site from low (including the unloading / loading area) to high level. However, since the number of staff of Yuen Fat Building and Cargo/ Uploading/ Loading Area is few and their frequency of view is intermittent, the sensitivity of these VSRs is considered to be low.

VSR W03 Staff and Students of Sir Ellis Kadoorie Secondary School

8.5.42   Sir Ellis Kadoorie Secondary School is situated at the southeast of the Site and staff and students are occupational receivers to the Site.  The viewers may have “glimpse to partial view” to the Site where the view of the Site is largely blocked by CLP Tai Kok Tsui Substation and cargos of unloading / loading area.  The sensitivity of these VSRs is considered to be low.

VSR W04 Staff of CLP Tai Kok Tsui Substation

8.5.43   CLP Tai Kok Tsui Substation (TKT S/S) is located immediately adjacent to the Site. Since there is no opening on the façade facing to the Site, the viewers may have “glimpse view” to the Site when the users in CLP S/S watch directly to the Site.  The sensitivity of these VSR is considered to be low.

VSR T01 Travellers of Wholesale Market Street

8.5.44   These VSRs represent transient passers that comprise frequent travellers including staff of Wholesale Market and travellers using the car parks and occasional travellers from elsewhere.  The VSRs may experience glimpsed to full views of the Site when they are travelling along Wholesale Market Street.  Considering that the VSRs are transient in nature, the sensitivity to the Site is low.

VSR T02 Travellers of Yen Chow Street West

8.5.45   These VSRs represent transient passers that comprise frequent travellers including staff of Wholesale Market, CLP TKT S/S, Yuen Fat Building and cargo unloading / loading area, staff and students of Sir Ellis Kadooris Secondary School and Tai Kok Tsui Catholic School (Hoi Fan Road) and travellers using the car parks at wholesale market and occasional travellers from elsewhere.  The VSRs may experience glimpsed to full views of the Site when they are travelling along the street.  Considering that the VSRs are transient in nature, the sensitivity to the Site is low.  Figure 8-11 displays the existing views and the photomontages showing the views of the Site from Nam Cheong Station Exit on Yen Chow Street West (Viewpoint 1).

VSR T03 Travellers of Yen Ming Road

8.5.46   These VSRs represent transient passers that comprise frequent travellers including staff of CLP TKT S/S, Marine Police Operation Base, MTR Pump House, Water Supplies Department (WSD) Salt Water Pump Station, staff and students of Sir Ellis Kadooris Secondary School and Tai Kok Tsui Catholic School (Hoi Fan Road), and travellers going into Hoi Fan Road and occasional travellers from elsewhere.  The VSRs may experience full views of the Site when they are travelling along Yen Ming Road.  Considering that the VSRs are transient in nature and the population is very few, the sensitivity to visual change to the Site is low. 

VSR T04 Travellers of Hoi Fan Road

8.5.47   These VSRs represent transient passers that comprise frequent travellers including staff of Marine Police Operation Base, MTR Pump House, Water Supplies Department (WSD) Salt Water Pump Station, staff and students of Sir Ellis Kadooris Secondary School and Tai Kok Tsui Catholic School (Hoi Fan Road), and occasional travellers from elsewhere.  The VSRs may experience partial to glimpsed views of the Site where the views will be blocked by existing roadside trees and settlements when they are travelling along Yen Ming Road.  The sensitivity to visual change to the Site is low.

VSR T05 Travelling of West Kowloon Highway

8.5.48   These VSRs represent transient passers travelling to and fro Kowloon.  The VSRs may experience partial to glimpse views of the Site as the view will be blocked by existing roadside trees.  The sensitivity to visual change to the Site is low.

VSR T06 Travelling of Lin Cheong Road

8.5.49   These VSRs represent transient passers travelling along.  The VSRs may experience partial to glimpse views of the Site where the views will be blocked by existing roadside trees, West Kowloon Highway and the footbridge across.  The sensitivity to the Site is low.

VSR RE01 Visitors of Nam Cheong Park

8.5.50   These VSRs represent occasional visitors to the park.  The VSRs may experience partial to glimpse views of the Site while the views will be blocked by existing landscaped trees in the park, which have high amenity value, as well as West Kowloon Highway.  The sensitivity to the Site is low.

VSR P01 Users / Travellers of Open Carpark next to Wholesale Market

8.5.51   The car park is situated next to Wholesale Market which is located immediately to the west of the Site.  These VSRs comprise occasional travellers and users of the uncovered car parks who are considered to be transient passers-by in these areas.  These VSRs may occasionally view the Project site but their views are often blocked by the existing trees and fences separating the car parks and Wholesale Market.  Users of the car parks are considered to be of low sensitivity as they are occupied by parking activities and will not stay for a long time.

VSR P02 Users / Visitors of Wholesale Food and Fish Markets

8.5.52   The Wholesale Food and Fish Markets is situated to the immediate west of the Site, These VSRs comprise occasional users and visitors of the Markets for buying food and fish in the morning.  They are considered to be transient passers-by in these areas. These VSRs may occasionally view the Project site but their views are often blocked by the fences separating the Markets and Yen Chow Street West and other settlements. The viewers are considered to be of low sensitivity as they will only stay for a short period of time for buying food.

VSR P03 Users / Travellers of West Kowloon Cargo Handling Area (including marine frontage)

8.5.53   These VSRs comprise the users and travellers of the cargo handling area, including the to and fro Stonecutter Island (marine frontage).  These VSRs may have limited partial view of the Site are often blocked by the existing cargos of their work area.  Also, these VSRs will be easily distracted by the sea view of much higher amenity value than that of the Site.  They are therefore considered to be of low sensitivity to the Site.

8.5.54   Table 8‑8 summarises the identified VSRs and their sensitivity.

Visual Sensitive Receivers (VSRs) with Planned Development

8.5.55   In view of the proposed comprehensive residential and commercial development above Nam Cheong Station, views of residents of Fu Loy House, Fu Ying House and Fu Yuet House of Fu Cheong Estate (VSR R01) will be significantly blocked, and residents of the proposed comprehensive residential and commercial development above Nam Cheong Station will become the visual sensitive receiver (VSR RP01) instead.  Figure 8-8 displays the extent of various VSRs with planned development within the study area.  Due to small scale of the proposed development, views of more distant view of the harbour area, which are considered to have much higher amenity value compared to that of the Site, will feature much more prominently in the visual envelop for residents within this planned development. Therefore, the sensitivity of these VSRs is considered to be low. The sensitivity of VSR RP01 is summarised in Table 8‑8.

8.6.1     The potential sources of landscape impacts from the proposed Depot during construction phase are mainly arisen from site clearance including removal of existing vegetation.

8.6.2     According to the tree survey, out of the 16 trees surveyed within project boundary, 15 trees are in direct conflict with the proposed car parking spaces and access road for the vehicle depot. All 15 trees are of the invasive exotic species, Leucaena leucocephala (銀合歡), which is considered as an undesirable, self-seeded weedy species. All of them are proposed to be removed during site clearance work. 

8.6.3     The remaining tree of Bombax ceiba will be retained on-site and may require pruning.

8.6.4     Table 8-9 summarises the number of trees for each type of recommendation in the Site. Figure 8-5 and Appendix 8-4 indicates the tree recommendations for all the surveyed trees within the project boundary.

8.6.5     Despite of the exotic and invasive nature of Leucaena leucocephala, magnitude of change of LR 5-3 during construction phase is large because the trees to be felled are exactly located at LR 5-3 where the local context of the Site would be changed significantly, it will therefore cause direct impact from construction activities.  As a result of low sensitivity and large magnitude of change, impact arisen from the proposed Depot during construction phase is considered moderate.

8.6.6     In contrary, magnitude of change of other LRs, including LR 1, LR 2, LR 3, LR 5 (except LR 5-3) and LR 6, as well as the LRs with planned development (LR 1-P1 and LR 6-P1) are considered as negligible since there is no direct change to the regional context due to construction activities of the proposed Depot.  Hence, the impacts of the proposed Depot during the construction phase are considered to be negligible.

8.6.7     Table 8‑10 summarises the significant threshold of landscape impact on LRs of the proposed Depot.

8.6.8     Similarly, magnitude of change of LCA 4 during construction phase is large since the proposed Depot would be built on the vacant land landscape where the existing vegetation (15 trees) would be felled.  As a result of low sensitivity and large magnitude of change, a moderate impact is anticipated during the construction of the proposed Depot.

8.6.9     Similar to LRs, magnitude of change of other LCAs, i.e. LCA 1, LCA 2, LCA 3, LCA 5 and LCA 6 is considered to be negligible as there is no direct change on them due to construction activities.  As a result, the anticipated impacts of all LCAs except LCA 4 during construction phase are considered to be negligible.

8.6.10   Table 8‑11 summarises the significant threshold of landscape impact on LCAs of the proposed Depot.

Operation Phase

8.6.11   During the operation phase, the sources of landscape impact are mainly the presence of the permanent structure of the proposed Depot and its operation.

8.6.12   While there is no direct conflict of the operation of the proposed Depot with other LRs, except LR 5-3, the magnitude of change remains negligible during the operation phase.  Due to the fact that the landscape resource of LR 5-3 would be occupied by the permanent structure of the proposed Depot, its magnitude of change remains large and a moderate impact is anticipated.

8.6.13   Similarly, the magnitude of change of all LCAs, except for LCA 4, remains negligible during the operation phase.  Since part of the landscape character areas of vacant land would be occupied by the permanent structure of the proposed Depot, its magnitude of change remains large and moderate impact was resulted.

8.7         Visual Impact Assessment

Construction Phase

8.7.1     The potential sources of visual impacts from the proposed Depot during construction phase are mainly arisen from site clearance including temporary establishment of site office and associated work area, operation of site works, presence of numerous machineries and equipment as well as material stockpiling, and the incremental movement of site vehicles around.  According to the construction programme as stated in Appendix 3-1, the proposed construction works would tentatively commence in 2013 and last for approximately 24 months.

8.7.2     In view of the limited footprint of the proposed works as discussed in above sections, and the potential blockage of view of all existing VSRs, except VSR T02, VSR T03 and VSR P02 is from glimpse to partial, the magnitude of change of the these VSRs, including those residential, occupational, travelling VSRs except VSR T02, VSR T03 as well as both travelling and occupational VSRs except VSR P02, is negligible. Hence their visual impact is considered not significant due to construction activities.  However, due to the close proximity of VSR T02, VSR T03 and VSR P02 to the Site where these VSRs may have glimpse to full view of the Site, the construction activities may impose some visual impact on the viewers.  Nevertheless, in view of their transient nature of use, the magnitude of change of VSR T02, VSR T03 and VSR P02 due to the construction activities is considered as small.  As a result, with low sensitivity and small magnitude of change, slight visual impacts are anticipated.

8.7.3     It is expected that the construction of the proposed Depot would be commenced before the establishment of the proposed comprehensive residential and commercial development above Nam Cheong Station. Therefore, no magnitude of change or visual impact are anticipated for VSR RP-01 during the construction phase.

8.7.4     On the other hand, the Yuen Fat Building and cargo unloading / loading area is located immediate opposite to the Site, however, due to the daily operation of the building and unloading / loading areas, the staff (VSR W02) may rarely view the Site, magnitude of change of VSR W02 is considered as small.  Hence, impact is considered to be slight.

8.7.5     Considering there is no opening on the façade facing the Site of CLP Tai Kok Tsui Substation, the staff (VSR W04) may only have rare views of the proposed Depot and negligible impact is anticipated though the substation is situated immediate adjacent to the Site.

8.7.6     Table 8‑12 and Table 8‑13 summarise the significant threshold of visual impact on VSRs of the proposed Depot.

Operation Phase

8.7.7     During the operation phase, the sources of visual impact are also the presence of the permanent structure of the proposed Depot, and thus its operation and vehicles parking, as well as the incremental numbers of vehicles, e.g. refuse collection vehicles (RCVs), travelling to and fro the Site.

8.7.8     Due to the limited scale of development of the proposed Depot while the potential blockage of view is glimpse to partial, magnitude of change for residential, occupational except VSR W02, travelling except VSR T02 and VSR T03 and both occupational and travelling VSRs except VSR P02, remain negligible and hence the visual impact is considered as negligible.  Due to the close proximity of the Site and transient nature of the VSR W02, VSR T02, VSR T03 and VSR P02, magnitude of changes of these VSRs remains small as the construction phase.  As a result, slight impacts for VSR W02, VSR T02, VSR T03 and VSR P02 respectively are anticipated arising from permanent structure of the proposed Depot.

8.7.9     Regarding the proposed comprehensive residential and commercial development above Nam Cheong Station (VSR RP01), despite the small scale of the Site, due to the close proximity between VSR RP01 and the proposed depot, the magnitude of change is considered as small, and therefore the visual impact of the viewers is therefore considered slight.

8.8         Mitigation Measures

8.8.1     The identification of the landscape and visual impacts highlights the potential primary sources of impacts and their magnitude of change caused to LRs/LCAs/VSRs. Corresponding mitigation measures are proposed to avoid and reduce the identified sources of impacts, and to remedy and compensate unavoidable impact.  The potential landscape and visual enhancement is also considered in the proposed mitigation measures.

8.8.2     The proposed mitigation measures during construction phase include:

·           CMM1: Control of construction activities;

·           CMM2: Temporary landscape treatment during construction phase;

·           CMM3: Tree Preservation

8.8.3     The proposed mitigation measures during operation phase include:

·           OMM1: Proper arrangement of materials during operation phase; and

·           OMM2: Landscape design, consisting of:

o  OMM2.1: Ground Floor Planting

o  OMM2.2: Vertical Greening

o  OMM2.3: Roof Gardens

o  OMM2.4: Hard Landscape features

CMM1 – Control of Construction Activities

8.8.4     Proper control of construction activities can effectively minimise the disturbances to VSRs.  The operation and placement of the construction plant and machinery, as well as the transportation and storage of material should be cautiously arranged in a way that the potential adverse impacts can be reduced and confined in certain areas in the Site.  The height of temporary structures such as hoardings and site offices should be minimised and the temporary construction sites shall be restored locally to the existing condition so as to minimise any negative impacts and associated uncomfortable views.  Site boundaries shall be checked regularly to ensure that the working area does not exceed and causes further damage to the surrounding area.  Also, in case of nighttime construction is conducted, control of nighttime lighting on the works areas to prevent undesired light pollution to the surrounding area, such as viewers from roads, should be implemented.

CMM2  Temporary Landscape Treatment

8.8.5     Provision of temporary landscape treatment during construction phase, such as temporary planting around the site office, applying aesthetic treatments on site hoardings and/or façade of site office, as well as providing green roof of site office, would lessen the visual disturbance to the surroundings arising from construction activities.

8.8.6     Examples of aesthetic treatments on site hoardings and green roof of site office can be referred to Figure 8-12.

CMM3 – Tree Preservations

8.8.7     There will be 1 nos. of tree to be retained on the site and thus the measures should be implemented during construction phase, such as  erection of fencing around the trees, avoidance of placing any construction materials close to the trees, apply mulching beyond root collar and also conduct visual checking / monitoring in regular basis.

OMM1 – Proper Arrangement of Materials during Operation

8.8.8     The majority of operational activities, including vehicle repair, maintenance, operation and parking, will be carried out within the depot-cum-office building. Some vehicles parking will occur in the uncovered car parks facing Lin Cheong Road.  Given that most of the vehicles at the said uncovered car parks are light vehicles such as staff shuttle buses, 4-seats cars, instead of RCVs, it will not cause any significant adverse impacts to the visual quality of the VSRs.

OMM2 – Landscape Design

8.8.9     In order to soften the hard concrete structure of the proposed depot-cum-office building, ground floor planting, façade greening and roof gardens have been incorporated into the landscape design.  The design enables more functional outdoor space to accommodate a range of passive uses as well as to enhance the aesthetics of views by the staff working in the Depot.  Soft and hard landscape areas are arranged in a relaxed, contemporary style to create an inviting and comfortable landscape.

OMM2.1 – Ground Floor Planting – Pedestrian Zone

8.8.10   Tree planting with upright columnar form are proposed along the north fence wall to soften the edges and provide visual interest at the streetscape level and to maximise the amount of green space accessible to the public.  It also enhances the streetscape amenity for pedestrians passing by from the MTR station, and enables screening of views from VSRs into vehicle maintenance depot. Similar trees planting will be taken along the west building façade to soften its edges and to enhance the main entrance.  Feature trees are proposed at the northwest and southwest corners of the building to provide a strong vertical visual highlight.

8.8.11   An approximate 630m2 of tree and shrub planting and groundcovers are proposed for pedestrian zone planting. A mix of native and ornamental species is proposed in Appendix 8-5.

OMM2.2 – Vertical Greening

8.8.12   Extensive vertical greening with area of about 330 m2 would be introduced to the Depot to screen views of the parking structure and enhance the visual amenity of the building facades.  Climbing plants, such as Lonicera japonica, Pyrostegia venusta, Quisqualis indica, Tristellateia australasiae, are recommended to maximize the coverage and screening of parking levels.  Planters located on each level of parking will provide sufficient space for the climbers to spread across grills incorporated into the architectural facades.

OMM2.3 – Roof Gardens

8.8.13   A multi-layered landscape is created using varying levels of planting, paving and landscape features in order to complement the strong architectural lines.  Trees, shrubs and groundcovers with different textures, colours, and fragrances provide a rich overlay to the terraces providing year round visual interest for users of the roof landscape as well as for those viewing the roof garden from their workspaces.  An area of about 1,400m2 of shrub species is proposed to be provided either in built-in planters or large feature pots.  Trees will be planted either in planters or in ornamental pots.  A mix of native and ornamental shrubs and groundcovers will be planted to articulate the spatial arrangements as well as to further add to the visual amenity.  A mix of local natural stone materials and recycled products will be explored for the paving and landscape features for both the pedestrian and roof areas. Recommended tree and shrub species are listed in Appendix 8-5.

OMM2.4 – Hard Landscape features

8.8.14   Other than the soft landscape, hard landscape features such as natural locally materials and recycled products for paving, sitting out areas, as well as vertical green fence wall along existing footpath on Lin Cheung Road would be explored provide contemporary landscape for users.  This improves the visual quality of the office interior and exterior spaces and integrates the themes on both soft and hard landscape characters.  Examples of landscape finishes can be referred to Appendix 8-6.

8.8.15   A total of 27 trees on-grade and on 3/F would serve as compensation to 15 nos. of trees to be felled in accordance with requirements set in ETWB TC(W) No. 3/2006. All the proposed mitigation measures would be managed and maintained by FEHD to ensure the effectiveness throughout the operation phase of the Project.

8.8.16   Appendix 8-7 shows the mitigation measures and conceptual master landscape design for this Project.

8.9         Residual Impacts

Landscape Impact during Construction Phase

8.9.1     During the construction phase, 15 trees that are in direct conflict with the proposed car parking spaces and access road for the vehicle depot will be felled with compensation in compliance with ETWB TC(W) No. 3/2008, already incorporated in the conceptual landscape master plan. Despite of the limited scale of development, the construction of the proposed Depot involves removal of existing 15 trees. There are still slight residual impacts on LCA 4 but moderate residual impacts on LR 5-3. The impacts on LCA 4 and LR 5-3 are both acceptable as the impact will be eliminated and the construction phase is temporary in nature.

Landscape Impact during Operation Phase

8.9.2     As previously discussed, planting of a mix of native and ornamentals special will be provided.  A total of 27 trees would serve as compensation to 15 nos. of trees to be felled in accordance with requirements set in ETWB TC(W) No. 3/2006.  At Day 1 of operation, the planting is not mature enough. The magnitude of change is small. With proper and regular maintenance, the planting will become mature and thus magnitude of change will be reduced to negligible in Year 10 when the mitigation measures are already established.

Visual Impact during Construction Phase

8.9.3     With the implementation of mitigation measures of CMM1, CMM2 and CMM3 during construction phase, the magnitude of change of VSR W02, VSR T02, VSR T03 and VSR P02, would become negligible since the visual quality and amenity of the Site have been improved. As a result, the residue visual impacts for all VSRs would become negligible.

Visual Impact during Operation Phase

8.9.4     Following the completion of construction activities, given the proposed depot consists of low-rise structures that will have minimal impacts on visual openness to the environment, the magnitude of change at Day 1 is small. However, the magnitude of change would further reduce as the proposed landscape mitigation measures would help screen the operational phases and soften the impact of the building on the surrounding landscape. At Year 10, the trees and shrub planting will have matured further screening views for the surrounding VSRs to have more greenery view, magnitude of change become slight. 

8.9.5     Summary tables for the residual impact for LRs/LCAs/VSRs after implementing mitigation measures are shown in Tables Table 8‑10, Table 8‑11, Table 8‑12 and Table 8‑13.

8.9.6     In view of the results discussed above, landscape and visual impact induced from the construction of the proposed Depot is therefore acceptable, with the implementation of mitigation measures.

8.10       Cumulative Impact

8.10.1   Cumulative landscape and visual impacts during the construction and operation phase of the Projects and other projects in the vicinity are assessed. Key projects identified are planned football pitch and basketball court at vacant land to the south of Tai Kok Tsui Catholic Primary School (Hoi Fan Road) and the proposed comprehensive residential and commercial development above Nam Cheong Station to be established in the year of 2017 to 2019 by phase whereas there is no construction programme of the football pitch and basketball court at Hoi Fan Road during the course of report, while the proposed Depot will be constructed in 2014 and in operation in 2017. Therefore, cumulative impact of the proposed project with the proposed football pitch and basketball court  are not assessed in this study, while cumulative impact of the proposed project with the proposed comprehensive residential and commercial development above Nam Cheong Station is not anticipated.

8.11       Environmental Monitoring and Audit

Construction Phase

8.11.1   Given the limited footprint of the proposed Depot, no significant impacts on the identified LRs and LCAs will be anticipated except for impacts on LR 5-3 Vacant Land Vegetation and LCA 4 Vacant Land due to felling of 15 common trees of the Site.  Construction site hoardings should be erected to surround the site to minimise the landscape and visual impacts on viewers from road level.  No monitoring is recommended during the construction phase. 

Operation Phase

8.11.2   The Project will result in the felling of 15 trees within the Site.  The landscape design as mentioned in Sections 8.8.9 to 8.8.13 are adopted as mitigation measures to compensate for the trees lost, which is proposed to plant 27 nos. compensatory trees of heavy standard size (100mm DBH) on-grade and on 3/F, exceeding minimum compensatory requirements as per the requirement in accordance with ETWB TC(W) No. 3/2006 i.e. in a compensatory ratio not less than 1:1 in terms of both quality and quantity. Planting of these trees would be completed before the completion of construction work of the Project.  Approval on tree felling would be obtained from the relevant government departments including Lands Department. The compensatory plantings would be implemented and any necessary monitoring of the compensatory planting after establishment would be conducted (if required) according to the tree felling approval conditions as required by the approval authorities.

8.12       Conclusions

8.12.1   LCAs, LRs and VSRs have been identified and their Sensitivity has been evaluated.  Magnitude of Change to LCAs, LRs and VSRs during construction and operation phases before and after implementation of recommended mitigation measures have been compared.

8.12.2   Out of the total 16 trees surveyed within the Site, 15 trees, which are of the invasive exotic species, Leucaena leucocephala (銀合歡), which is considered as an undesirable, self-seeded weedy species, are in direct conflict with the proposed car parking spaces and access road for the vehicle depot and are proposed to be removed during site clearance work.  Despite of the exotic and invasive nature of Leucaena leucocephala, magnitude of change of LR 5-3 during construction phase is large because the trees to be felled are exactly located at LR 5-3 where the local context of the Site would be changed significantly, it will therefore cause direct impact from construction activities.  Similarly, magnitude of change of LCA 4 during construction phase is large. As a result of low sensitivity and large magnitude of change, a moderate impact for LR 5-3 and LCA 4 is anticipated during the construction of the proposed Depot.

8.12.3   The potential sources of visual impacts from the proposed Depot during construction phase are mainly arisen from site clearance including temporary establishment of site office and associated work area, operation of site works, presence of numerous machineries and equipment as well as material stockpiling, and the incremental movement of site vehicles around.  Due to the close proximity of VSR T02, VSR T03 and VSR P02 to the Site where these VSRs may have glimpse to full view of the Site, the construction activities may impose some visual impact on the viewers.  Nevertheless, in view of their transient nature of use, the magnitude of change of VSR T02, VSR T03 and VSR P02 due to the construction activities is considered as small.  As a result, with low sensitivity and small magnitude of change, slight visual impacts are anticipated. Following the completion of construction activities, the magnitude of change would further reduce as the proposed landscape mitigation measures would help screen the operational phases and soften the impact of the building on the surrounding landscape. At Year 10, the trees and shrub planting will have matured further screening views for the surrounding VSRs.

8.12.4   With the implementation of mitigation measures such as control of construction activities and temporary landscape treatment during construction phase, the proposed Depot will inevitably result in some landscape impact but no adverse visual impact during the construction phase, On the contrary, ground floor planting, vertical greening and roof gardens will be provided for the proposed Depot during operation phase. Both landscape and visual impact would become negligible in Year 10 when the mitigation measures are already established.

8.12.5   Comparing with the original setting of the Site before the proposed project where undesirable and weedy species are located at the Site, the overall landscape character and visual quality of the Site would be improved, with the provision of landscape design including ground floor planting at pedestrian zone, vertical greening and roof gardens for the proposed Depot. According to Annex 10 of EIAO-TM, the landscape and visual character of the Site have been complemented and therefore landscape and visual impact arising from the proposed Depot is considered as beneficial.
