7.3.                     Planning and Development Control Framework

7.3.1.               A review of the existing and planned development for the proposed works and for the surroundings has been undertaken. It aims at gaining insight to the future outlook of the potentially affected area, identifying issues with neighbouring planned land uses, identifying potential resources and sensitive receivers and ensuring a high compatibility between the proposed Project and the surroundings.

7.3.2.               The Site is located near the promenade of Chai Wan Public Cargo Working Area. The Site falls within an area zoned as ¡§Government, Institution or Community (G/IC(2))¡¨ on the latest Chai Wan Outline Zoning Plan (OZP) No. S/H20/21, which is always permitted for Government use. Therefore, application for permission under Section 16 of the Town Planning Ordinance is not required.

7.3.3.               According to the Notes of the OZP, the planning intention of the zone is intended ¡§for the provision of Government, institution or 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 uses directly related to or in support of the work of the Government, organizations providing social services to meet community needs, and other institutional establishments.¡¨ As mentioned in Section 2.2, the proposed Project would provide facilities for uses directly related to and in support of the work of the Government to meet community needs, such as the provision of FEHD vehicle depot allows the FEHD to provide quality environmental hygiene services and the provision of PVP&EC for the HKPF to enhance road safety and maintain smooth and safe traffic flow in Hong Kong. Therefore, the proposed Project satisfies the planning intention.

7.3.4.               The Project site is surrounded by areas zoned as G/IC(2), where Government buildings and public bus depots have been developed. The proposed Project is consistent with the visual character of the area.

7.3.5.               As described in Section 3, the proposed Project is a six-storey building with building height of +49.8 mPD, which complies with the height restriction of 70 mPD as stipulated on the OZP for the subject site. The building height of the proposed Project is also within the range of building heights of the surrounding developments, which is between 19.6 mPD and 71 mPD.

7.3.6.               The provision of tree planting and shrubs on Level 1 along the subject site boundary as mentioned in Section 7.8.6 and 7.8.7 is also consistent with Section 6.2.41 of the Urban Design Guideline in Hong Kong Planning Standards and Guidelines, which recommends the provision of landscape areas along streets to soften hard edges and to reduce heat build-up of street environment.

7.3.7.               There is no specific requirement on landscape strategy, landscape framework, designed view corridors, open space network and landscape link for the proposed Project.

7.3.8.               Outline Development Plan (No. D/H20A/1A), neighbouring OZPs (i.e. Nos. S/H18/10 and S/TKO/21) and planning briefs have also been reviewed. Potential developments shall be anticipated at the vacant land at the junction of Shing Tai Road and Sheung Mau Street and the public open parking space located at the junction of Shing Tai Road and Chong Fu Road, which are zoned as ¡§Government, Institution or Community (G/IC(2))¡¨on the latest Chai Wan OZP. However, there is no programme of the two potential developments during the course of the report and is therefore not assessed in this study. No committed or planned development is identified other than the planned THEi New Campus.

7.3.9.               The findings of the planning and development control review on areas within the Landscape Impact Assessment Area are summarised in Table 7.1.

7.4.                     Assessment Methodology

Landscape Baseline Review and Impact Assessment

Identification of Landscape Resources and Landscape Character Areas

7.4.1.               A baseline study of the existing landscape resources (LRs) and landscape character areas (LCAs) was conducted based on desktop study and field surveys to identify and examine the existing landscape elements that contribute to landscape character of the study area, which is within 500m from the Project site boundary in accordance with clause 3.4.10.2 of the Study Brief. The size and scale of the study area is considered as sufficient to provide representative data for the assessment. Basic landscape elements include topography, natural landscape form and patterns of settlement of built features, lands use, streetscapes, and any cultural historical and/or religious identity.

7.4.2.               A tree survey has been conducted within the Project site and its immediately adjacent areas to identify the landscape resources and quality with respect to the tree species characters, ecological/conservation value, health and structure conditions of the existing trees of the Site.

7.4.3.               The LCAs formed by various broadly homogenous units of similar landscape characters within the study area have been mapped and annotated on a plan.

Methodology of Landscape Impact Assessment

7.4.4.               Potential impacts arisen from the construction and operation stages of the proposed Project were assessed.

7.4.5.               The sensitivity of LRs/LCAs are normally influenced by the importance or rarity, quality and maturity of the landscape elements, the ability of the elements to accommodate change, and the significance of the change in local and regional context. The sensitivity was assessed as follows:

¡P             High: an important component or a landscape of particularly distinctive character susceptible to small changes;

¡P             Medium: a landscape with moderately-valued characteristics reasonably tolerant to change; and

¡P             Low: a relatively unimportant landscape that is able to accommodate extensive change.

7.4.6.               The magnitude of change to LRs/LCAs depends on the scale of the proposed Project, compatibility of the proposed Project with the surrounding landscape, duration of impacts under construction and operation phase, and reversibility of change. The magnitude is classified as follows:

¡P             Large: notable change in landscape characteristics over extensive area, or very intensive change over a more limited area;

¡P             Intermediate: moderate change to local area;

¡P             Small: changes limited to components; and

¡P             Negligible: no perceptible change.

7.4.7.               The system for the assessment of the overall landscape impact is summarised in Table 7.2 below. The significance of landscape impact has been derived from the combined analysis of the magnitude of change and the sensitivity of the LRs/LCAs to the change in accordance with Section 3.7 (f) of EIAO GN No. 8/2010. The significance is defined as follows:

¡P             Significant: the landscape resource/landscape will experience major change;

¡P             Moderate: the landscape resource/landscape will experience moderate change;

¡P             Slight: the landscape resource/landscape will experience slight or barely perceptible change; and

¡P             Insubstantial: the landscape resource/landscape will experience unnoticeable change.

Visual Baseline Review and Impact Assessment

Baseline Review of Visual Envelop and Identification of Visual Sensitive Receivers

7.4.8.               The assessment area for the visual impact assessment has been defined as the visual envelop (VE) that is generally the viewshed formed by natural or manmade features such as ridgeline or building blocks according to EIAO GN No. 8/2010 and is considered as sufficient to provide representative data for the assessment. The visibility of the proposed Project from key groups of visual sensitive receivers (VSRs) has been determined through site surveys and desktop study of topographical plans and aerial photographs.

7.4.9.               The key VSRs are categorised according to the nature of settlement as follows:

¡P             VSRs-H: residential VSRs that view the proposed Project from homes. They are considered as the most sensitive due to the potential of intrusion on their home environment and the associated quality of life;

¡P             VSRs-O: occupational VSRs that view the proposed Project from workplaces, institutional and educational buildings. They are considered as relatively less sensitive since the visual amenity will be less important to their quality of life;

¡P             VSRs-R: recreational VSRs that view the proposed Project from recreational landscapes. Their sensitivity to change varies depending on the types of recreational activity, and

¡P             VSRs-T: travelling VSRs that view the proposed Project from public roads and railways during travelling on vehicles or on foot. Their sensitivity to change is the least in general.

Methodology of Visual Impact Assessment

7.4.10.           Potential visual impacts arisen from the construction and operation stages of the proposed Project were assessed.

7.4.11.           The sensitivity of VSRs are normally influenced by the value and quality of existing views, availability and amenity of alternative views, type and estimated number of receiver population, duration or frequency of view, and degree of visibility. The sensitivity of the VSRs to change is rated as ¡§high¡¨, ¡§medium¡¨ or ¡§low¡¨.

7.4.12.           Typical viewpoint (vantage point) has been identified and photograph showing the current view was taken.

7.4.13.           The magnitude of change for in view to the VSRs depends on the scale of the proposed Project, compatibility of the proposed Project with the surrounding landscape and planned setting, duration of impacts under construction and operation phases, reversibility of change, viewing distance and potential blockage of view. The magnitude is classified as follows:

¡P             Large: major changes in view to the VSRs

¡P             Intermediate: moderate changes in view to the VSRs

¡P             Small: minor changes in view to the VSRs

¡P             Negligible: no discernible change in view to the VSRs

7.4.14.           The significance of visual impact has been derived from the combined analysis of the magnitude of change and the sensitivity of the VSRs to the change in accordance with Section 3.7(f) of EIAO GN No. 8/2010. The significance is defined as follows:

¡P             Significant: the VSRs will experience major change in view;

¡P             Moderate: the VSRs will experience moderate change in view;

¡P             Slight: the VSRs will experience slight or barely perceptible change in view; and

¡P             Insubstantial: the VSRs will experience unnoticeable change in view.

7.4.15.           The system for the assessment of the overall visual impact is summarised in Table 7.2 above.

Identification of Potential Mitigation Measures

7.4.16.           Wherever possible and necessary, mitigation measures have been considered in order to avoid, reduce, remedy or offset the adverse impacts resulting from the proposed Project. Impact avoidance would be the priority. If impacts cannot be avoided, alternative measures have been explored on methods of reduction and/or compensation.

Residual Impacts

7.4.17.           The residual impacts after implementation of the recommended mitigation measures are identified and assessed. The significance of impacts are classified into five levels with reference to Annex 10 of the EIAO-TM as follows:

¡P             The impact is beneficial if the proposed Project would complement that the landscape and visual character of its setting, follow the relevant planning objectives and improve overall landscape and visual quality;

¡P             The impact is acceptable if the assessment indicated that there would be no significance effects on the landscape, no significant visual effects caused by the appearance of the proposed Project, or no interference with key views;

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

¡P             The impact is unacceptable if the adverse effects would be considered too excessive and unable to mitigate practically;

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

Photomontage

7.4.18.           The visual impacts and the proposed mitigation measures are demonstrated using photomontage to illustrate existing views and future views (Day 1 to Year 10) from key VSRs to illustrate existing conditions and the conditions during operation phase in relation to other developments and prominent visual features. Three viewpoints have been selected for preparing the photomontages (refer to Figure 7.6) as described below:

¡P         Vantage Point 1 (VP1): VP1 is located at ground level of Block E of Pamela Youde Nethersole Eastern Hospital to represent a general view of the Project site from residents on the West. Although these VSRs will have a distant view of the Project site, their frequency of view and the potential affected population are relatively high.

¡P         Vantage Point 2 (VP2): VP2 is located at 5/F of Hong Kong Institute of Vocational Education (Chai Wan). It is the only occupational VSRs that have direct view of the Project site along their view corridors of the harbour area. The potential affected population of these VSRs are expected to be intermediate.

¡P         Vantage Point 3 (VP3): VP3 is located at various levels of Tsui Shou House in Tsui Wan Estate. It represents the view of the Project site from residents on the South that have relatively high viewing frequency and potential affected population.

¡P         Vantage Point 4 (VP4): VP4 is located at ground level on Sheung On Street near the intersection with Sheung Mau Street. It represents the travelling VSRs that are close to the Project site and have a direct view of the Project site. The potential affected population of these VSRs are expected to be low.

7.5.14.           Although the basin area belongs to natural resources and cannot be re-created, its coastline has been straightened to form the cargo handling area and is trafficked by container ships. LR8 is considered to have medium amenity value with high sensitivity.

7.5.15.           Sensitivity of the existing landscape resources are listed in Table 7.3.

Landscape Resources (LRs) with Planned Development

7.5.16.           A planned THEi New Campus will nearly be established when the construction of the proposed Project commences in mid-2016 tentatively. However, as no design detail of the Campus is available during the course of report, the landscape resource would be assessed under the current condition of the area as LR6-1, i.e. open space or vacant land bounded by Shing Tai Road, Sheung Ping Street, Sheung On Street and Wing Tai Road, in baseline assessment.

Landscape Character Areas (LCAs)

7.5.17.           A total of seven 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 7.2. These areas include:

LCA1 ¡V Hillside Landscape

7.5.18.           LCA1 is approximately 8.12ha in size. It refers to the natural hillside woodland surrounding Pamela Youde Nethersole Eastern Hospital and its adjoining vegetated engineered slope connected to the natural hillside woodland of Tai Tam Country Park. In LCA1, the vegetated engineered slope consists of both native woodland and plantation, while most of the natural woodland is dominated by native secondary woodland tree species, including Alangium chinense, Bridelia tomentosa, Ficus hispida, Litsea glutinosa, Macaranga tanarius, Mallotus paniculatus, Sapium discolor, Sterculia lanceolata, and woody climbers such as Byttneria aspera, understory herbs such as Alpinia hainanensis, with canopy gaps invaded by exotic weeds such as Leucaena leucocephala, the exotic climber Ipomoea cairica and Mikania micrantha. LCA1 is the type of LCA that is very sensitive to disturbances due to its naturalness of native woodland and good linkage with the natural hillside habitats and the Tai Lam Country Park. Therefore, LCA1 is considered to have high amenity value with high sensitivity.

LCA2 ¡V Community/Residential Urban Landscape

7.5.19.           LCA2 is approximately 28.97ha in size. It refers to the built up and densely populated area in Chai Wan District dominated by high-rise residential buildings and medium to high-rise buildings of community services such as schools and hospitals, flyovers and roads trafficked by vehicles. It is considered as the largest LCA within the study area and is one the most common landscape character in Hong Kong. It consists of roadside plantings and residential plantings with dominant tree species of Acacia confuse, Bombax ceiba, Delonix regia, Ficus microcarpa, Spathodea campanulata, Ficus microcarpa and dominant ornamental shrubs such as Alpina zerumbet, Chrysalidocarpus lutescens and Philodendron selloum. Although the landscape quality in LCA2 is fair to good in general due to regular maintenance, it comprises of human-created landscape feature only and can be re-created easily. As a result, LCA2 is considered to have low to medium amenity value with medium sensitivity.

LCA3 ¡V Park Landscape

7.5.20.           LCA3 is approximately 3.15ha in size. It refers to the rest gardens and other sitting-out areas in the study area that provides recreational open space to the public. As described in Section 7.5.4 for LR3, it is dominated by mature species, including Acacia confusa, Bauhinia sp., Ficus microcarpa, Lagerstroemia speciosa and Melaleuca quinquenervia, and planted ornamentals, such as Philodendron selloum and Thryallis gracilis, in good health conditions with high amenity values. Although LCA3 comprises of the human-created landscape features and can be re-created easily, this type of LCA is uncommon in the study area and is therefore considered to have high sensitivity.

LCA4 ¡V Industrial Urban Landscape

7.5.21.           LCA4 is approximately 9.50ha in size. It refers to the built-up area dominated by industrial buildings along the coast of Chai Wan Public Cargo Working Area. It is a common landscape character in Chai Wan district and Hong Kong. Since LCA4 comprises of man-made features that are highly resilient to changes of disturbances, it is considered to have low sensitivity.

LCA5 ¡V Railway Viaduct Landscape

7.5.22.           LCA5 is approximately 5.65ha in size. It refers to the MTR viaduct connecting Chai Wan MTR Station and Heng Fa Chuen MTR Station. It is a very common man-made feature that forms a prominent visual obstruction to viewers and is highly resilient to changes or disturbances. LCA5 is considered to have low amenity value with low sensitivity.

LCA6 ¡V Marine Landscape

7.5.23.           LCA6 is approximately 33.84ha in size. It refers to the cargo handling basin and its adjoining designated cargo handling area bounded by Sheung On Street and Ka Yip Street. It is only partially visible to travellers on Sheung On Street and Ka Yip Street due to the existing screens and fencing. However, it becomes prominent to viewers at medium to high level, such as the viewers from adjacent buildings. The water bodies of LCA6 are natural landscape resources and cannot be re-created. Therefore, LCA6 is considered to have medium amenity value with high sensitivity.

LCA7 ¡V Open Car Parks/Maintenance Workshops/Vacant Land Landscape

7.5.24.           LCA7 is approximately 6.48ha in size. It refers to the uncovered car parks, vacant lands and open space for use as temporary work sites/maintenance workshops/bus depots along Sheung On Street, including the Project site. Naturally-established vegetation could be found within the area with dominant species of Carica papaya, Ficus hispida, Macaranga tanarius, Leucaena leucocephala and a few planted ornamentals such as Ficus benjamina and Ligustrum sinense. This type of LCA is common in urban areas throughout Hong Kong and comprises human-created landscape feature only. LCA7 is considered to have low amenity value with low sensitivity.

Landscape Character Areas (LCAs) with Planned Development

7.5.25.           As discussed in Section 7.5.16, the vacant land at the junction of Wing Tai Road and Shing Tai Road will be occupied by the planned THEi New Campus. Since the Campus will nearly be established when the construction of the proposed Project commences in mid-2016, this area would be categorized as LCA2 in the baseline assessment. The sensitivity of existing landscape character areas are listed in Table 7.4.

Existing Trees within Project Site

7.5.26.           A total of 37 tree species were identified within or close to the Project site boundary as included in Appendix 7.1. 36 numbers of the surveyed trees were non-native species such as Bombax ceiba and Carica papaya, while 1 number of native species, Broussonetia papyrifera, was found at the Eastern corner within the Project site. Of the total 37 trees, 6 trees (or ~16% of the surveyed trees) were found to have poor tree form but generally in fair health condition, 9 trees (or ~25% of the surveyed trees) were found to be in poor health and tree forms, and 6 trees (or ~16% of the surveyed trees) were found in generally fair health and tree form. The 16 remaining trees (or ~ 43% of the surveyed trees), which are Bombax ceiba located just outside the South-western and North-western boundary of the Project site, were found in good health and form. Table 7.5    summarises the tree species composition within the survey area.

7.5.27.           No registered or potential Old and Valuable Trees (OVT) were recorded during the tree survey and no rare or protected species were encountered. Detailed information of the surveyed trees is presented in the Tree Assessment Schedule in Appendix 7.1.

7.5.28.           Of the total 37 trees surveyed, 12 trees would be of direct conflict with the proposed Project, including 9 trees located within the Project footprint. Among these 9 trees, 6 trees belong to the exotic tree species, Carica papaya, that are common with low amenity value, 2 trees belong to the exotic tree species, Bombax ceiba, that are poor in health with low amenity value due to the deformed tree form, and 1 tree belong to the native species, Broussonetia papyrifera, that is in poor form and health due to inadequate maintenance. The remaining 3 trees are Spathodea campanulata located outside the South-eastern boundary of the Project site. Table 7.6 summarises the number of trees for each type of recommended treatment. The tree recommendation for all surveyed trees is shown in Figure 7.3.

7.5.29.           According to DEVB TC(W) No. 10/2013, these trees are undesirable for transplanting and thus proposed for felling due to the low post-transplanting survival rate and low amenity value.

7.5.30.           In addition to the 37 trees surveyed, the proposed Project will be of direct conflict with 2 additional plants located outside the Eastern corner of the Project boundary. However, the two plants are not considered as trees in accordance with DEVB TC(W) No. 10/2013 as their trunk diameters are less than 0.95m at the height of 1.3m above ground level. Hence, they are excluded from the survey.

Existing Visual Context

Visual Envelop (VE) and Zone of Visual Influence (ZVI)

7.5.31.           For the purposes of the assessment, the visual envelop (VE) of the proposed Project is divided into Primary VE and Secondary VE. The Secondary VE comprises of areas that are far from the Project site but the site visible with naked eyes, i.e. across the harbour. Although there will be a direct line of sight of the Project site within the Secondary VE in a small number of cases, these VSRs should not be able to detect perceptible changes from the proposed Project due to the long viewing distance. Therefore, the magnitude of change from these VSRs and the resulting visual impact should be ¡§negligible¡¨ and ¡§insubstantial¡¨ respectively.

7.5.32.           As compared to Secondary VE, the Primary VE comprises of areas that are relatively closer to the Project site and is defined as the zone of visual influence (ZVI). The ZVI is largely confined by Pamela Youde Nethersole Eastern Hospital on the West, Tsui Wan Estate and Chai Wan Industrial Estate on the South, the industrial buildings along Ka Yip Street on the East, and the NWFB Depot on the North. The assessment area is focused within the Primary VE (i.e. ZVI).

7.5.33.           The coverage of Primary and Secondary VEs are shown in Figure 7.4a.

Visual Character and Resources

7.5.34.           The proposed Project is located in an area that is densely built with medium to high-rise industrial buildings and residential developments. The Project site is immediately surrounded by vacant lands, parking spaces, bus depots and cargo handling basin. Hence, the proposed Project is compatible with character of the surrounding environment.

7.5.35.           The key visual characters and resources within the ZVI or 500m from the boundary of the Project site are indicated in Figure 7.4b and includes:

¡P                Industrial buildings;

¡P                Residential developments;

¡P                Ridgelines;

¡P                Open space (i.e. parks);

¡P                Open carparks/ vacant lands;

¡P                Roadside vegetation/ green slopes;

¡P                MTR viaducts; and

¡P                Cargo handling basin/ harbour area.

7.5.36.           Among the identified key visual resources, ridgelines and cargo handling basin/ harbour area are considered as the most sensitive resources and have high amenity value to the VSRs. However, visual intrusion from the development of the proposed Project is not anticipated since the proposed Project has a building height that is similar to the building height of the adjacent NWFB Depot as mentioned in Section 3.8.2. The visual system between VSRs and the visual resources, such as the sensitivity and the ability to accommodate change, of the proposed Project is assessed in Section 7.7 and 7.9.

Key Visual Sensitive Receivers (VSRs)

7.5.37.           Within ZVI, the key VSRs are grouped according to the settlement of developments, travellers and occupational receivers of similar nature. The selected VSRs are representatives of views available to viewers at each of the following location:

¡P             Visible area with residential VSRs:

-       VSR-R1: Residents of Tsui Wan Estate (Tsui Shou House, Tsui Hong House, Tsui Fuk House);

¡P             Visible area with both travelling and occupational VSRs:

-       VSR-P1: Users/Staffs of ExxonMobil Petrol-cum-LPG Filling Station.

7.5.38.           Figure 7.5 shows the locations of the identified VSRs as described as follows:

VSR-R1: Residents of Tsui Wan Estate (Tsui Shou House, Tsui Hong House, Tsui Fuk House)

7.5.39.           In Tsui Wan Estate, the residents at medium to high level have a partially obstructed view of the Project site that is dominated by the building structures at the foreground with the harbour area and the natural hill slope across the harbour visible in background, while the views of the Project site at low level is dominated by the vegetation on Wing Tai Road and is substantially blocked the existing Citybus Depot. Since the sensitive receivers are residents, the sensitivities of these VSRs are considered to be high. Figure 7.6 displays the existing views and the photomontages showing the views of the Project site from Tsui Shou House (VP3).

VSR-R2: Residents of Knight Court

7.5.40.           These VSRs include the residents of Knight Court. The residents at medium to high level have a partially obstructed view of the Project site that is dominated by the building structures at the foreground with the harbour area in background, while the residents at low level is dominated and substantially obstructed by the existing roadside vegetation on Shing Tai Road and the MTR viaduct. Since the sensitive receivers are residents with partial to substantial obstruction of view of the Project area, the sensitivities of these VSRs are considered to be high.

VSR-R3: Residents of Pamela Youde Nethersole Eastern Hospital ¡V Blocks E, F, G

7.5.41.           These VSRs have a slightly obstructed distant view of the Project site by the Hong Kong Institute of Vocational Education (Chai Wan) and the Citybus Depot. The existing view of these VSRs is dominated by the building structures at the foreground with the harbour area and the natural hill slope across the harbour in background. In consideration of residential nature of these VSRs and the relatively long viewing distance, the sensitivities of these residential VSRs are considered to be medium. Figure 7.6 displays the existing views and the photomontages showing the views of the Project site from ground level of Block E of Senior Civil Servants Quarters (Vantage Point 1).

VSR-O1: Chai Wan Industrial City (Phase I and II), Cornell Centre

7.5.42.           These VSRs include the occupational receivers on the North-western and North-eastern side of the building. The existing view is dominated by the cargo handling basin at the foreground with the Project site visible in background. The existing view of the Project site is substantially blocked by the existing settlement and vessels in the cargo handling area, but the visual obstruction is reduced when viewing from medium to high level. However, as these VSRs are mostly workers, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, they are considered to be of low sensitivity to visual change to the Project site.

VSR-O2: Yiko Industrial Building, Paramount Building, Ming Pao Industrial Centre (Block A and B)

7.5.43.           These VSRs are occupational receivers on the North-western side of the buildings. The existing view is dominated by the cargo handling basin at the foreground with the Project site visible in background. The existing view of the Project site is substantially blocked by the existing settlement and vessels in the cargo handling basin, but the visual obstruction is reduced when viewing from medium to high level. As VSR-O2 are mostly workers, their visual perceptions are not very important and do not have a significant effect on their quality of life., Therefore, these VSRs are considered to have low sensitivity to visual change.

VSR-O3: Chivas Godown, Safety Godown Industrial Building, Kerry Godown (Chai Wan)

7.5.44.           Similar to VSR-O1 and VSR-O2, these occupational VSRs have an existing view that is dominated by the cargo handling basin at the foreground with the Project site visible in background. These VSRs have a relatively unobstructed view of the Project site except the partial blockage by the existing settlement at low level. As these VSRs are mostly workers, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, the sensitivities of these VSRs are considered to be low.

VSR-O4: Marine Department Chai Wan Public Cargo Working Area

7.5.45.           The existing view of these VSRs is dominated by the cargo handling basin at the foreground with the Project site visible in background. Their views of the Project site are substantially obstructed by the existing fencing of their work area and the vessels in the cargo handling basin. With consideration that these VSRs are mostly workers, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, their sensitivities to visual change are considered to be low.

VSR-O5: Pamela Youde Nethersole Eastern Hospital ¡V East Block

7.5.46.           The existing view of these VSRs is dominated by the building structures at the foreground with the harbour area and the natural hill slope across the harbour in background.  Their views of the Project site are partially blocked by the existing roadside vegetation and the Citybus Depot. As these VSRs are mostly workers, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, the sensitivities of these VSRs are considered to be low.

VSR-O6: Hong Kong Institute of Vocational Education (Chai Wan)

7.5.47.           These VSRs are the occupational users on the Eastern side of the buildings with existing views dominated by roadside vegetation and MTR tracks and viaduct. Views of the Project site from these VSRs are partially to significantly blocked by the MTR viaduct and the existing roadside vegetation on Shing Tai Road. As these VSRs are mostly students and staffs who are expected to have fewer chances to view the Project site when they are in class, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, the sensitivities of these VSRs are considered to be low. Figure 7.6 displays the existing views and the photomontages showing the views of the Project site from the Hong Kong Institute of Vocational Education (Chai Wan) (VP2).

VSR-T1: Travellers at Sheung On Street

7.5.48.           These VSRs represent transient passers that comprise frequent travellers including mainly workers from the cargo handling area and the bus depots on Sheung On Street, and occasional travellers from elsewhere. At location where the Project area is the most clear, the existing view of the Project site, which is dominated by building structures of the bus depots and roadside vegetation, is partially obstructed by roadside vegetation. Given that VSR-T1 are travellers and their views are transient in nature, the sensitivities of these VSRs to visual change to the Project site are considered to be low. Figure 7.6 displays the existing views and the photomontages showing the views of the Project site from travellers on Sheung On Street near the intersection with Sheung Mau Street (VP1).

VSR-T2: Traveller at Sheung Mau Street

7.5.49.           These VSRs represent transient passers that comprise frequent travellers including mainly the users of the ExxonMobil Petrol-cum-LPG Filling Station, staffs of NWFB Depot, and occasional travellers from elsewhere. At location where the Project area is the most clear, the existing view of the Project site is dominated and partially obstructed by the roadside vegetation on Sheung Mau Street. Although these VSRs may experience partial to full views of the Project site when they are travelling along Sheung Mau Street. With consideration that these VSRs are transient in nature, their sensitivities to visual change are considered to be low.

VSR-T3: Travellers at Sheung Tat Street

7.5.50.           These VSRs represent transient passers that comprise frequent travellers mainly from the staffs of NWFB Depot. At location where the Project area is the most clear, the existing view of the Project site, which is dominated by the building structures of NWFB Depot and roadside vegetation, is partially obstructed by the roadside vegetation. Given that the VSRs are transient in nature, their sensitivities to visual change are low.

VSR-T4: Travellers at Shing Tai Road

7.5.51.           These VSRs represent transient passers travelling along Shing Tai Road. At location where the Project area is the most clear, the existing view of the Project site is dominated and partially obstructed by the roadside vegetation along Shing Tai Road and Sheung Mau Street. Given that the VSRs are transient in nature, their sensitivities to visual change are low.

VSR-T5: Travellers at Ka Yip Street

7.5.52.           These VSRs comprise mainly transient passers including workers of the cargo handling area and the adjacent industrial buildings, and occasional travellers from elsewhere. At location where the Project area is the most clear, the existing view of the Project site, which is dominated by building structures and the fencing of the cargo handling area, is substantially obstructed by the fencing and vessels in the cargo handling basin. With consideration of its transient nature and the substantial blockage of view, these VSRs are considered to have low sensitivities to visual change.

VSR-P1: Users/Staffs of ExxonMobil Petrol-cum-LPG Filling Station

7.5.53.           These VSRs comprise staffs of the ExxonMobil Petrol-cum-LPG Filling Station and occasional users who are considered to be transient passers-by in these areas. The existing views of these VSRs are dominated by the existing roadside vegetation along Sheung Mau Street, which partially obstructed their views of the Project site. Users of the gas station are considered as travellers and their views are transient in nature. Staffs of the Station are expected to have few chances to view the Project site during work and their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, these VSRs are considered to have low sensitivities.

Visual Context of Planned Development

VSR-O7: Planned THEi New Campus

7.5.54.           Since the planned college will be in operation tentatively from the third quarter of 2016, VSR-O7 will nearly be established when the construction of the proposed Project commences and is therefore included in the baseline assessment.

7.5.55.           These VSRs represents the occupational users on the Northern side of the planned college. The existing views of these VSRs are dominated by the building structures at the foreground with the harbour area and the natural hill slope across the harbour in background. Their views of the Project site at high level are partially obstructed by roadside vegetation, while the views from medium to low levels are substantially blocked by the Citybus Depot. As these VSRs are mostly students and staffs that are expected to have fewer chances to view the Project site when they are in class, their visual perceptions are not very important and do not have a significant effect on their quality of life. Therefore, VSR-O7 is considered to have low sensitivity to visual change.

7.5.56.           Based on the best available information at the time of the EIA study, no major change in the existing environmental condition is anticipated in the future in the absence of the proposed Project.

7.5.57.           Table 7.7 summarises the identified VSRs and their sensitivity to change.

7.6.                     Landscape Impact Assessment

Construction Phase

7.6.1.               The potential sources of landscape impact during construction phase are mainly arisen from site clearance including removal of existing vegetation.

7.6.2.               According to the tree survey, 12 trees would be of direct conflict with the proposed Project. Transplanting is considered undesirable due to the low post-transplanting survival rate and low amenity value according to DEVB TC(W) No. 10/2013.

7.6.3.               The proposed tree felling involves 9 trees within the Project site (i.e. LR7-2) and 3 trees at the South-eastern boundary of the Project site (i.e. LR4-4), along which there are other existing large trees surrounding the Project site to be retained that provides screening effect to the Project site as illustrated in the photomontage at VP2 in Figure 7.6. The resulting magnitude of landscape change from the proposed tree felling is considered as small at both LR4-4 and LR7-2. Hence, slight adverse impact is anticipated at LR4-4 and LR7-2 during construction phase.

7.6.4.               For other LRs, the magnitude of change is considered as negligible since there is no direct change on landscape resources due to the construction activities of the proposed Project. Therefore, the overall landscape impact arisen from the proposed Project during construction phase is considered as insubstantial for all LRs except LR4-4 and 7-2.

7.6.5.               Since the proposed Project will be built on lands with a landscape character of maintenance workshop (LCA7), it is consistent and compatible with the current landscape character of the Project site, but would have a small magnitude of change due to a minor loss of greenery within the Project site and at the site boundary, i.e. the felling of 9 trees in LCA7 and 3 trees in LCA2. As a result of low sensitivity and small magnitude of change, slight adverse impact is anticipated at LCA 2 and LCA7 during the construction of the proposed Project.

7.6.6.               Similar to LRs, there is no direct change to the setting and landscape character of all LCAs other than LCA 2 and LCA7 due to the construction activities of the proposed Project. The significance of landscape impact arisen from the proposed Project during construction phase is considered as insubstantial for all LCAs except LCA2 and LCA7.

Operation Phase

7.6.7.               The sources of impact during operation phase are mainly the presence of the permanent structure of the proposed Project and its operation.

7.6.8.               A small portion of the landscape resources of LR4-4 and LR7-2 will be occupied by the driveway and the permanent structure of the proposed Project. However, there are still other existing large trees surrounding the Project site, such as LR4-4 and LR4-5 as illustrated in the photomontage at VP2 in Figure 7.6. Hence, the magnitudes of change for LR4-4 and LR7-2 during operation phase are considered as small due to the screening by the retained trees along the Project site boundary. Therefore, the impacts arisen from the proposed Project during operation phase at LR4-4 and LR7-2 are considered as slightly adverse.

7.6.9.               For other LRs, the magnitude of change is considered as negligible since there is no direct conflict of the operation of the proposed Project with all landscape resources. Therefore, the significance of landscape impact arisen from the proposed Project during operation phase is considered as insubstantial for all LRs other than LR4-4 and LR7-2.

7.6.10.           As the proposed land use of the Project site would be in line with other maintenance workshops in the vicinity and is compatible with the current landscape character of the Project site (i.e. LCA7), the magnitude of change of LCA7 during operation phase is considered as small. Due to the loss of greenery from the proposed tree felling in LCA2 is considered minor in nature, the magnitude of change of LCA2 is also considered as small. As a result, slight adverse impact is anticipated at LCA2 and LCA7 during operation phase.

7.6.11.           Similar to construction phase, the magnitude of change of all other LCAs, i.e. LCA1, LCA3, LCA4, LCA5 and LCA6, during operation phase is considered as negligible since there is no direct change on the landscape character areas due to the operation of the proposed Project. Therefore, the significance of landscape impact arisen from the proposed Project during operation phase is considered as insubstantial for all LCAs except LCA2 and LCA7.

7.6.12.           Table 7.8 and Table 7.9 Table 7.9 summarise the significant threshold of landscape impact on LRs and LCAs of the proposed Project respectively. The mapping of significant threshold of landscape impact is shown in Figure 7.7.

Visual Impact without Mitigation during Construction Phase

VSR-R1: Residents of Tsui Wan Estate (Tsui Shou House, Tsui Hong House, Tsui Fuk House)

7.7.1.               The existing view of the Project site, which is dominated by building structures, roadside vegetation and harbour area, will change to a construction site that remains partially blocked by the existing Citybus Depot and roadside vegetation. However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, the distant views of the harbour area and natural hillslope will not be blocked by the proposed Project and are more prominent with much higher amenity value as compared to that of the Project site. Therefore, the magnitude of change is adversely small and the resulting visual impact is moderately adverse during construction phase.

7.7.7.               The existing view of the Project site, which is dominated by the cargo handling basin, will change to a construction site that is substantially obstructed by the existing fencing of their work area and vessels in the cargo handling basin. In addition, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, the sea view of the cargo handling basin will not be blocked by the proposed Project and is more prominent with higher amenity value than that from the Project site.

7.7.8.               The existing view of the Project site, which is dominated by the building structures, harbour area and the natural hill slope, will change to a construction site that is partially obstructed by the existing roadside vegetation and the Citybus Depot. However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, these VSRs are easily distracted by the harbour area and the hill slope landscape that will not be blocked by the proposed Project and are more prominent with higher amenity value than that from the Project site.

However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, these VSRs are easily distracted by the roadside vegetation on Shing Tai Road that will not be blocked by the proposed Project and is more prominent with higher amenity value than that from the Project site. Therefore, with consideration of their close proximity to the Project site, the magnitude of change is adversely intermediate and the resulting visual impact is slightly or moderately adverse during construction phase.

VSR-T1: Travellers at Sheung On Street

7.7.10.           The existing view of the Project site, which is dominated by the building structures of bus depots and roadside vegetation, will change to a construction site that remains partially obstructed by the existing roadside vegetation. Although 3 roadside trees on Sheung On Street are proposed to be felled due to direct conflict with the proposed Project,, there are a variety of alternative views that will not be blocked by the proposed Project and are considered to be more prominent with higher amenity value than that of the Project site, i.e. the remaining roadside vegetation and sea view of the cargo handling basin. Therefore, with consideration of their occasionally view of the Project site, the magnitude of change is adversely intermediate and the resulting visual impact is slightly or moderately adverse during construction phase.

Potential Visual Impact without Mitigation

7.7.33.           The potential visual impact without mitigation measures for individual VSRs are derived from the sensitivities and magnitude of changes in accordance with Table 7.2 and summarised in Table 7.11. The mapping of significant threshold of visual impact is shown in Figure 7.8.

7.8.                     Mitigation Measures

7.8.1.               The identification of landscape and visual impacts highlights the potential sources of impacts and their magnitude of change caused to LRs, LCAs and VSRs. Corresponding mitigation measures are proposed to avoid and reduce the identified impacts and to remedy and compensate unavoidable impact as well as providing potential landscape and visual enhancement.

Mitigation Measures during Construction

CM1 ¡V Construction Site Hoarding

7.8.2.               Hoardings should be provided with aesthetic treatment and designed to be subtle and camouflaged. It should be compatible with the surrounding landscape and visually ¡§impermeable¡¨ to block the view of construction activities from VSRs. The visual quality and amenity value of the Project site would be enhanced as compared to the existing condition of the Project site that consists of temporary works area surrounded by grey hoarding.

CM2 ¡V Temporary Landscape Treatment

7.8.3.               Temporary landscape treatment, such as the provision of temporary planting around the Site office in ornamental pots and application of green roof for Site office, should be considered during construction phase. Landscape planting in movable planters should also be considered as a temporary greening measure for the Project area (i.e. along Site hoarding). Design of the green roof and the type of species to be used shall be reviewed and confirmed during detailed design stage. The visual quality and amenity value of the Project site is considered to be enhanced by the provision of a more greenery view to the neighbourhood as compared to the existing condition of the Project site that consists of temporary works area with exposed soil and trees in poor health condition.

CM3 ¡V Preservation of Existing Vegetation

7.8.4.               Disturbance to existing vegetation should be avoided as far as practicable. Where possible, the construction programme should retain all trees in situ that are not in direct conflict with the development proposals. Subject to the detailed design of the proposed Project, a review shall be carried out before commencement of construction phase to assess the potential conflict of the construction activities with existing roadside trees and the need of corresponding measures. Proper protective fencing should be provided by the Contractor to protect the preserved trees before commencement of any works within the Project site. The protective fencing should be erected along or beyond the perimeter of the tree protection zone of each individual tree.

Mitigation Measures during Operation

OM1 ¡V Compensatory Planting

7.8.5.               Compensatory planting should be provided in the landscape area on Level 1 for the 12 trees that are proposed to be felled. The planting would follow the requirements as stipulated in DEVB TC(W) No. 10/2013, such as the provision of compensatory trees of heavy-standard size in a ratio of 1:1 in terms of number and aggregate diameter at breast height (DBH). A preliminary compensatory planting plan is provided in Figure 7.9. The planting location and the type of compensatory plant species will be reviewed and confirmed during detailed design stage. The planting should be commenced during construction stage and be completed before the completion of construction stage to ensure the measure will be implemented on Day 1 of operation stage. Vegetation maintenance should be provided by the Operator. A compensatory tree planting proposal should be submitted together with tree removal application for approval by authorities in later stage. The compensatory planting would provide screening of the Project¡¦s operation together with the retained roadside vegetation and softens the impact of the permanent structure of the proposed Project. The planting would also create a more greenery view with healthy vegetation to the neighbourhood and enhance the visual quality and the amenity value of the surrounding environment as compared to the existing condition of the Project site that consists of temporary works area with exposed soil and trees in poor health condition with low amenity value.

OM2 ¡V Landscape Planting near Pedestrian Zone

7.8.6.               Landscape areas should be provided along the Site boundary on Level 1 to soften the built structure of the proposed Project. An approximate of 700m2 of trees, shrubs or groundcovers shall provide year-round streetscape amenity as well as enhancing visual interest at street level. A mix of native and ornamental trees, shrubs or groundcovers shall be planted to articulate the spatial arrangements as well as to further add to the visual amenity. The type of species to be used will be confirmed during detailed design stage. The planting should be commenced during construction stage and be completed before the completion of construction stage to ensure the measure will be implemented on Day 1 of operation stage. Vegetation maintenance should be provided by the Operator. The planting further enhances the screening effect together with the compensatory trees, which would create a more greenery view with healthy vegetation to the neighbourhood and enhance the visual quality and the amenity value of the surrounding environment as compared to the existing condition of the Project site that consists of temporary works area with exposed soil and trees in poor health condition with low amenity value.

OM3 ¡V Green Roof

7.8.7.               A multi-patch of landscape area should be provided on the roof of the proposed building to soften the impact of the built structure. An area of approximately 2600m2 of shrub, which comprises of a mix of native and ornamental species, is proposed to be provided to enhance the aesthetics of views for those viewing the roof. The type of shrub species will be confirmed during detailed design stage. The planting should be commenced during construction stage and be completed before the completion of construction stage to ensure the measure will be implemented on Day 1 of operation stage. Vegetation maintenance should be provided by the Operator. The planting would create a more greenery view with healthy vegetation to the neighbourhood, particularly for the sensitive receivers where the roof of the proposed Project is visible, and enhance the visual quality and the amenity value of the surrounding environment as compared to the existing condition of the Project site that consists of temporary works area with exposed soil and trees in poor health condition with low amenity value.

OM4 ¡V Hard Landscape Feature and Lighting Design

7.8.8.               In order to blend in with the surrounding environment, the exterior of the permanent structure of the proposed Project should use non-reflective external finishes in light colour that is visually unobtrusive with surrounding context. Non-reflective paving materials should be considered to reduce potential glare from surface reflectance. Sample colours of the hard structures of the proposed Project are provided in Figure 7.10 for indicative purpose. The finishing material and colour will be reviewed and confirmed during detailed design stage.

7.8.9.               Lighting should be efficiently designed so that minimum amount of lighting is required for safety and security. The design may make reference to the Guidelines on Industry Best Practices for External Lighting Installations by Environmental Bureau, EPD and EMSD. The mounting height and direction of exterior lighting fixtures shall be designed and arranged to point away from sensitive receivers where possible. Specification of lighting operation schedule shall be formed by the operator to impose restriction on lighting operation after business hours, such as limiting the operation of lighting except for security lighting only, and in areas with necessary night-time operation where applicable.

7.8.10.           The operator should provide regular maintenance for the proposed mitigation measures to ensure the effectiveness of the measures. The mitigation measures are illustrated in the preliminary master landscape plan in Figure 7.11a and 7.11b.

7.9.                     Residual Impacts after Mitigation

Landscape Impact during Construction Phase

7.9.1.               During the construction phase, 12 trees that are in direct conflict with the driveway and the permanent structure of the proposed Project are proposed to be felled with compensation in compliance with DEVB TC(W) No. 10/2013. Since the proposed Project is in limited scale and the existing use of the Project site is for temporary works with exposed soil and machinery already, LR4-4, LR7-2, LCA2 and LCA7 will experience insubstantial residual impact from the proposed tree felling and construction activities with proper implementation of the proposed mitigation measures, such as control of construction programme and erection of site hoarding to screen-off construction activities. Therefore, the impacts on LR4-4, LR7-2, LCA2 and LCA7 are considered insubstantial as the construction phase is temporary in nature and the impact will be eliminated.

Landscape Impact during Operation Phase

7.9.2.               Except for the 12 trees that are in direct conflict with the proposed Project, the remaining landscape resources in the study area, which are considered having high amenity value to the sensitive receivers in the vicinity of the proposed Project in general, will be retained. The proposed Project will also be in line with other maintenance workshops in the vicinity to preserve the current landscape character of the Project site (i.e. LCA7) to minimise the magnitude of change and potential visual impact to VSRs. Although a minor loss of existing trees, which are in poor form and health with low amenity value, will result from the proposed Project, the landscape quality is anticipated to be enhanced as the compensatory planting will provide healthy trees to compensate for the felled trees that are in poor health with low amenity value. In addition, the existing temporary works area with exposed soil within the Project site will also be replaced by the proposed Project that consists of multi-patches of vegetation on pedestrian level and roof floor to further improve the landscape and visual quality. The preservation of existing landscape character area and the minor destruction of the existing landscape resources, which are in poor form and health with low amenity value, are considered as beneficial in general.

7.9.3.               As stated in Section 7.8.5 to 7.8.7, trees, shrubs or groundcovers will be provided in the landscape area on Level 1 and roof floor. Compensatory planting will also be provided on Level 1 for the 12 trees that are proposed to be felled in accordance with DEVB TC(W) No. 10/2013. When the planting becomes mature in Year 10, the magnitude of change at LR4-4, LR7-2, LCA2 and LCA7 will be reduced to negligible. Therefore, and residual landscape impact in operation phase is insubstantial when the mitigation measures are established.

Visual Impact during Construction Phase

7.9.4.               With mitigation, the existing view of the Project site, which is dominated by building structures, roadside vegetation and harbour area, will change to a construction site with screen hoarding and temporary landscape planting. The view of the Project site from these VSRs would remain partially blocked by the existing Citybus Depot and roadside vegetation. However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, the distant views of the harbour area and natural hillslope will not be blocked by the proposed Project and are more prominent than that from the Project site, which are considered to have much higher amenity value as compared to that of the Project site. Therefore, the magnitude of change is adversely small and the resulting visual impact is moderately adverse during construction phase.

However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, the distant view of the harbour area will not be blocked by the proposed Project and is more prominent than that from the Project site, which is considered to have much higher amenity value as compared to that of the Project site. Therefore, the magnitude of change is adversely small and the resulting visual impact is moderately adverse during construction phase.

7.9.6.               With mitigation, the existing view of the Project site, which is dominated by building structures, harbour area and natural hill slope across the harbour, will change to a construction site with screen hoarding and temporary landscape planting. The view of the Project site from these VSRs would remain slightly obstructed by the Hong Kong Institute of Vocational Education (Chai Wan) and the Citybus Depot. In addition, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, these VSRs are easily distracted by the harbour area and the hill slope landscape that will not be blocked by the proposed Project and are more prominent with higher amenity value than that from the Project site. Therefore, the magnitude of change is adversely small and the resulting visual impact is slightly or moderately adverse during construction phase.

The view of the Project site from these VSRs would have slight to partial obstruction by the existing settlement. However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, these VSRs are easily distracted by the sea view of the cargo handling basin that will not be blocked by the proposed Project and is more prominent with higher amenity value than that from the Project site.

The view of the Project site from these VSRs would have partial to substantial obstruction by the MTR viaduct and the roadside vegetation. However, due to the small scale of the proposed Project and the existing use of the Project site as temporary work site with low visual amenity value, these VSRs are easily distracted by the roadside vegetation on Shing Tai Road that will not be blocked by the proposed Project and is more prominent with higher amenity value than that from the Project site. Therefore, with consideration of their close proximity to the Project site, the magnitude of change is adversely intermediate and the resulting visual impact is slightly or moderately adverse during construction phase.

7.9.13.           With mitigation, the existing view of the Project site, which is dominated by the building structures of bus depots and roadside vegetation, will change to a construction site with screen hoarding and temporary landscape planting. The view of the Project site from these VSRs would remain partially obstructed by the existing roadside vegetation. Although 3 roadside trees on Sheung On Street are proposed to be felled, there are a variety of alternative views that will not be blocked by the proposed Project and are considered to be more prominent with higher amenity value than that of the Project site, i.e. the remaining roadside vegetation and sea view of the cargo handling basin. Therefore, with consideration of their occasionally view of the Project site, the magnitude of change is adversely intermediate and the resulting visual impact is slightly or moderately adverse during construction phase.

7.9.20.           With mitigation, the existing view of the Project site, which is dominated by building structures, roadside vegetation and harbour area, will be replaced by the hard structure of the proposed Project with pre-mature landscape planting and green roofs in Day 1 of operation. Since the proposed Project is built with a building height as similar to the adjacent NWFB Depot, the corridor of open harbour view, which is of much higher amenity value and more attractive as compared to that of the Project site, is not be affected. The visual impacts on these VSRs are moderately adverse in Day 1 of operation. As the landscape plantings of the proposed Project matures in Year 10 of operation, thereby having better screening effect on the hard structures together with the partial viewing blockage by the existing Citybus Depot and roadside vegetation, the visual impact is expected to be slightly adverse in Year 10 of operation.

The visual impact will remain slightly adverse in Year 10 of operation.

7.9.36.           The residual impacts for LRs, LCAs and VSRs after implementation of mitigation measures are summarised in Table 7.8, Table 7.9, Table 7.10 and Table 7.11. The mapping of significant threshold of landscape and visual impact are shown in Figure 7.7 and 7.8 respectively.

7.10.                 Cumulative Impact

7.10.1.           Cumulative landscape and visual impacts during the construction and operation phase of the proposed Project with other projects in the vicinity is assessed. According to the latest Chai Wan OZP, potential developments shall be anticipated at the vacant land at the junction of Shing Tai Road and Sheung Mau Street and the public open parking space located at the junction of Shing Tai Road and Chong Fu Road, which are zoned as ¡§Government, Institution or Community (G/IC(2))¡¨. However, there is no programme of the two potential developments during the course of the report and is thus not assessed in this study of cumulative impact of the proposed Project. Therefore, it is identified that the planned THEi New Campus is the only planned project in the vicinity.

7.10.2.           According to Table 3.3, the planned THEi New Campus will be in operation from the third quarter of 2016, which is approximately three months after the tentative commencement of the construction of the proposed Project in mid-2016. During the interfacing time, the anticipated works of the planned THEi New Campus are interior fitting-out and users moving-in according to Table 5.11. Therefore, the planned THEi New Campus would be completed and would not have landscape and visual impact when interfacing with the proposed Project.

7.10.3.           With consideration that the planned THEi New Campus is established during construction phase and operation phase of the proposed Project, the Campus forms part of the landscape and visual baseline and has been included in the impact assessment.

7.10.4.           Relevant Outline Development Plans, neighbouring OZP planning brief have also been reviewed. No other committed or planned development is identified.

7.11.                 Environmental Monitoring and Audit

Construction Phase

7.11.1.           No substantial impact is anticipated on LRs and LCAs, while slight to moderate visual impact is anticipated during construction phase. The impact will be minimised by the implementation of the mitigation measures as mentioned in Section 7.8.2 to 7.8.4, such as the preservation of existing vegetation and provision of construction site hoarding. The implementation of mitigation measures shall be checked via regular environmental site audit as part of the EM&A procedures as detailed in the EM&A Manual.

Operation Phase

7.11.2.           The proposed Project will result in the felling of 9 trees within the Project site and 3 trees on the South-eastern boundary of the Project site. The landscape design as described in Section 7.8.5 to 7.8.9 will be adopted as mitigation measures to compensate for the proposed tree felling as well as softening the visual impact arisen from the permanent structure of the proposed Project. A Tree Preservation and Removal Proposal (TPRP) should be prepared during detailed design stage in accordance with DEVB TC(W) No. 10/2013 to seek for approval of tree felling from relevant responsible department including the Lands Department, and the compensatory planting would be completed before completion of construction phase of the proposed Project. Therefore, EM&A work is considered not necessary in general. Subject to the tree felling approval conditions as required by the approval authorities, monitoring of the compensatory planting after establishment will be conducted, if required.

7.12.                 Conclusions

7.12.1.           A landscape and visual impact assessment covering a 500m study area for assessment of landscape impacts and the visual envelop for assessment of visual impacts has been conducted.

7.12.2.           The potential sources of landscape impact of the proposed Project during construction and operation phase mainly arisen from site clearance (i.e. removal of existing vegetation) and the presence of the permanent structure and its operation respectively.

7.12.3.           The potential sources of visual impacts from the proposed Project during construction and operation phase mainly arisen from the operation of site works (i.e. site clearance work, stockpiling of construction equipment, etc.) and the presence of permanent structure of the proposed Project respectively.

7.12.4.           The proposed Project would have no impact on any landscape resources and landscape character area within the study area except for the 12 trees that are of direct conflict with the proposed Project and therefore proposed to be felled. The impacts are slightly adverse due to the minor loss of greenery. With proper implementation of the proposed mitigation measures, such as the provision of landscape area and compensatory planting, the magnitude of change would be minimised and therefore the residual landscape impact would be insubstantial.

7.12.5.           The anticipated visual impacts from the proposed Project are generally slightly to moderately adverse during construction phase mainly due to slightly to partially obstructed views of construction activities. Following the completion of construction activities, the landscape planting and green roof of the proposed Project act as visual screen to visual sensitive receivers as well as enhance the visual quality and amenity value by the provision of a more greenery view to the neighbourhood as compared to the existing condition of the Project site, which consists of temporary works area with exposed soil and trees in poor health condition. The residual visual impact in operation phase is slightly adverse to insubstantial in general.

7.12.6.           Comparing the original setting of the Project site prior to the proposed Project, where trees in poor health and form with low amenity value are located, the overall landscape character and visual quality of the Project site would be improved with the provision of landscape design, including the incorporation of hard landscape design and the provision of landscape planting on Level 1 and green roof. Therefore, the landscape character and visual quality of the Project site have been complemented and the landscape and visual impact from the proposed Project is considered as acceptable with mitigation measures.
