7.3               Assessment Methodologies

Review of Planning and Development Control Framework

7.3.1           A review of the existing planning studies and documents has been undertaken as part of the baseline study to gain an insight into the planned role of the Project site, its surrounding areas, and its landscape context and to help to determine if the Project fits into the wider existing and future landscape context. This review has considered the approved Tai Po Outline Zoning Plan (OZP) No. S/TP/30. Compatibility of the Project to the landscape related land use and development control framework in the OZP.

Landscape Impact Assessment Methodology

7.3.2           The landscape assessment has been conducted in accordance with Appendix K of the EIA Study Brief No. ESB-321/2019 and with reference to the criteria and guidelines as stipulated in Annex 10 and 18 of EIAO-TM and EIAO Guidance Note No. 8/2010 to include all areas within 500m from the boundaries of the Project site (i.e. the 500m assessment area).

Identification and Examination of Baseline Landscape Resources and Landscape Character Areas

7.3.3           With reference to the most recently published EIA studies, literature, topographical maps and aerial photographs, available landscape resources (LRs) and landscape character areas (LCAs) within the 500m assessment area were identified and mapped on plan based on the government base map.

7.3.4           Supplementary field surveys were conducted to verify the extent and conditions of the identified LRs and LCAs.  LCAs are broader categorizations than LRs that encompass a number of different LRs. Each LCA is a consolidated character derived from holistic reviews of various LRs that result in an overall impression of the landscape.  LCAs in the 500m assessment area were mapped with reference to the Landscape Character Map of Hong Kong.

7.3.5           Possible landscape resources include physical landscape resources which are natural components of landscape such as soil, vegetation, water bodies (hydrology), geological and topographical features. In urban areas, man-made landscape resources include human/cultural landscape features such as parks, landscaped gardens, recreation areas, open spaces and community spaces. Urbanized areas with densely packed buildings and development infrastructure also comprise landscape resources such as buildings, retaining walls and formed slopes.

Broad-brush Tree Survey

7.3.6           A broad-brush tree survey was carried out in accordance with Appendix K of the EIA Study Brief to provide baseline information for the LRs and LCAs as well as to identify dominant tree species, overall amenity value and any plant species of conservation importance, etc. which would be potentially affected by the Project.

Assessment of Sensitivity of LRs / LCAs

7.3.7           The sensitivity of LRs and LCAs is rated as ¡¥high¡¦, ¡¥medium¡¦ or ¡¥low¡¦ and are influenced by rarity, importance, quality and maturity and the ability of LRs and LCAs to accommodate change.

Identification of Sources and Magnitude of Potential Landscape Impacts

7.3.8           Potential sources of landscape impacts could arise from both construction and operation of the Project.  The magnitude of changes for assessing landscape impacts depends on the following criteria:

n  Compatibility of the Project with the surrounding landscape;

n  Duration of impacts under construction and operational phases;

n  Scale of development; and

n  Reversibility of change.

7.3.9           The magnitude of landscape change is classified as follows:

n  Large: the landscape or landscape resources would suffer a major change;

n  Medium: the landscape or landscape resources would suffer a moderate change;

n  Small: the landscape or landscape resources would suffer slight or barely perceptible changes;

n  Negligible: the landscape or landscape resources would suffer no discernible change.

Recommendation of Landscape Mitigation Measures

7.3.10        Possible landscape mitigation measures may include minimization of extent and duration of construction works, adoption of alternative design, and compensatory measures such as provision of landscape planting/ vegetation.

7.3.11        The following approaches, in order of priority, are advocated:

n  Avoidance approach: to avoid direct impacts;

n  Minimization approach: to minimize impacts if avoidance is not possible; and

n  Compensation approach: to compensate for significant residual impacts when there is no other alternative available.

Significance of Residual Landscape Impacts

7.3.12        The significance of landscape impacts before and after implementation of mitigation and enhancement measures are defined as follows:

n  Substantial: Adverse/ Beneficial impact where the proposal would cause significant deterioration or improvement in existing landscape quality;

n  Moderate: Adverse/ Beneficial impact where the proposal would cause a noticeable deterioration or improvement in existing landscape quality;

n  Slight: Adverse/ Beneficial impact where the proposal would cause a barely perceptible deterioration or improvement in existing landscape quality;

n  Insubstantial: No discernible change in existing landscape quality.

7.3.13        The degree of significance of landscape impacts has been derived from the combination of the magnitude of change and the sensitivity/ tolerance of the sensitive receivers to change as shown in Table 7.1 below.

Visual Impact Assessment Methodology

7.3.14        The visual assessment has been conducted in accordance with Appendix K of the EIA Study Brief No. ESB-321/2019 and with reference to the criteria and guidelines as stipulated in Annex 10 and 18 of EIAO TM and EIAO Guidance Note No. 8/2010 to include all areas from which the Project could be seen.

Identification and Examination of Visual Envelope (VE) and Visually Sensitive Receivers (VSRs)

7.3.15        Geographical Information System (GIS) software was utilized to prepare the visual envelope. By analyzing the topography and dimensions of buildings, the areas that could potentially see the development during construction and operation can be worked out.  Further to the use of GIS, the study of aerial maps and site visits helped to establish locations that could and could not see the Project taking into account factors other than topography.

7.3.16        The local VSRs to be affected by the Project are categorized as follows.

n  Residential VSRs (R) ¡V who view the proposed Project from their homes;

n  Occupational VSRs (O) ¡V who view the proposed Project from their workplaces, institutional and educational buildings;

n  Recreational VSRs (V) ¡V who view the proposed Project when they are enjoying leisure, cultural or recreational activities;

n  Travelling VSRs (T) ¡V who view the proposed Project when they are travelling on vehicles.

Assessment of Sensitivity of VSRs

7.3.17        The sensitivity of VSRs to change is rated as ¡¥high¡¦, ¡¥medium¡¦ or ¡¥low¡¦ as influenced by the type and estimated population of VSRs, quality of existing views, availability of alternate views, duration or frequency of view and degree of visibility.

Identification of Sources and Magnitude of Potential Visual Impacts

7.3.18        Potential sources of visual impacts could arise from both construction and operational phases of the Project.  Visual impact assessment shall identify and predict the type and extent of visual impacts relating to visual compatibility with surroundings, visual obstruction and improvement of visual quality. The magnitude of changes for assessing visual impacts includes:

n  Compatibility of the Project with the surrounding landscape;

n  Duration of impacts under construction and operational phases;

n  Scale of development;

n  Reversibility of change;

n  Viewing distance; and

n  Potential blockage of view.

7.3.19        The magnitude of visual change is classified as follows:

n  Large: the VSRs would suffer a major change in their viewing experience;

n  Medium: the VSRs would suffer a moderate change in their viewing experience;

n  Small: the VSRs would suffer a small change in their viewing experience;

n  Negligible: The VSRs would suffer no discernible change in their viewing experience.

Recommendation of Visual Mitigation Measures

7.3.20        Possible visual mitigation measures will primarily take the form of adoption of alternative design/ orientation to avoid or minimize visual obstruction resulting from the Project, careful consideration in colour and texture treatment of building features and finishes to soften the visual effects; and provision of green features and screening to neutralize the negative impacts from hard elements.

7.3.21        Computer-generated photomontages will be prepared based on photographs taken at selected vantage points (to be selected and confirmed based on ground-truth surveys) to illustrate visual impacts on key VSRs at four stages (existing conditions, day 1 without mitigation measures, day 1 with mitigation measures and Year 10 with mitigation measures) to demonstrate the comparison of scenarios and the effectiveness of proposed mitigation measures over time.

Significance of Residual Visual Impacts

7.3.22        The significance of residual visual impacts before and after implementation of mitigation and enhancement measures are defined as follows:

n  Substantial: Adverse/ Beneficial impact where the proposal would cause significant deterioration or improvement in existing visual quality;

n  Moderate: Adverse/ Beneficial impact where the proposal would cause a noticeable deterioration or improvement in existing visual quality;

n  Slight: Adverse/ Beneficial impact where the proposal would cause a barely perceptible deterioration or improvement in existing visual quality;

n  Insubstantial: No discernible change in existing visual quality.

7.3.23        The degree of significance of visual impacts has been derived from the combination of the magnitude of change and the sensitivity of the visually sensitive receivers as shown in Table 7.5 similar to the matrix for determining significance of Landscape Impacts.

Overall Result of Landscape and Visual Impact Assessment

7.3.24        An overall assessment of the acceptability, or otherwise of the impacts according to the criteria in Annex 10 of the EIAO-TM has been conducted. The overall assessment has been made on the development based on the identified landscape and visual impacts described as follows.

n  Beneficial: The impact is beneficial if the Project will complement the landscape and visual character of its setting, will comply with the relevant planning objectives and will improve overall landscape and visual quality

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

n  Acceptable with Mitigation Measures: The impact is acceptable with mitigation measures if there will be adverse effects, but these can be eliminated, reduced or offset to a large extent by specific measures.

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

n  Undetermined: The impact is underdetermined 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.

7.4               Review of Planning and Development Control Framework

7.4.1           The proposed Project site falls within the approved Tai Po Outline Zoning Plan (OZP) No. S/TP/30. The land use zones within 500m assessment area is shown in Figure 7.1.

7.4.2           The Site falls within an area largely zoned ¡§Other Specified Uses¡¨ annotated ¡§Sewage Treatment Works¡¨ (¡§OU(STW)¡¨) subject to a maximum building height of 3 storeys, with a very minor portion zoned ¡§Other Specified Uses¡¨ annotated ¡§Industrial Estate¡¨ (¡§OU(IE)¡¨) on the approved Tai Po Outline Zoning Plan (OZP) No. S/TP/30. According to the Notes of the OZP, the proposed TPSTW upgrading works of not more than 3 storeys high are regarded as ¡¥Sewage Treatment Works¡¦ use, which is a Column 1 use always permitted on the OZP. For part of the subject site that falls within the ¡§OU(IE)¡¨ zone, planning permission is not required as it is a use permitted under a plan which was effected during the effective period of that plan and has continued since it was effected.

7.4.3           The maximum building height restrictions of ¡§OU¡¨ (Sewage Treatment Works) and ¡§OU¡¨ (Industrial Estate) are 3 storeys and 40 mPD, respectively. According to the latest design, the maximum no. of storeys of the building would be 3 with maximum height of not more than 40mPD, which are within the building height restrictions.

7.5               Landscape Baseline

Broad-brush Tree Survey

7.5.1           A broad-brush tree survey was carried out in 2021 and the survey findings are provided in Appendix 7.1.

7.5.2           It is estimated that a total of 15,170 nos. of trees are within the 500m assessment area. These trees are with height ranging from 1.5 to 18m and fair in health condition and tree form in general. The dominant tree species include Acacia confuse, Ficus microcarpa and Leucaena leucocephala, which contribute about 40% of total tree quantity.

7.5.3           A total of 530 nos. of trees of 51 species are identified within the proposed Project site. The trees are of fair health condition and tree form with height ranging from 1.5 to 18m.  The dominant tree species include Cinnamomum burmanni, Archontophoenix alexandrae and Syagrus romanzoffiana. There is no Old & Valuable Tree (OVT) but 1 no. of tree (i.e. one individual of Aquilaria sinensis) is of species of conservation importance. Eight individuals of Lagerstroemia speciosa were identified in the Project site, which are plant species listed under Forests and Countryside Ordinance (Cap. 96). However, as Lagerstroemia speciosa are exotic species commonly cultivated in urban area of Hong Kong, they are not considered species of conservation importance under this Project. Ten mature trees (DBH ≥ 1m / crown spread ≥ 25m), including six Ficus microcarpa and four Ficus benjamina, have been identified as tree of particular interest (TPI) (details refer to Appendix 7.1). A summary of tree species and their quantities recorded within the Project site is provided in Table 7.2.

7.6               Visual Baseline

Visual Envelope

7.6.1           The predicted visual envelope (VE) within 7km from the Project Site is illustrated in Figure 7.6. The VE extends to Shuen Wan Restored Landfill and Ma Shi Chau to the east, Ping Fung Shan to the north, Pak Tai To Yan to the west. Tai Po Kau to the south, Tiu Shau Ngam at Ma On Shan to the south-east.

Visually Sensitive Receivers

7.6.2           Within the VE, a total of 25 representative visually sensitive receivers (VSRs) have been identified and grouped into four types, namely Residential (R), Occupational (O), Recreational (L) and Travelling (T), as described in Section 7.3. The identified VSRs are listed in Table 7.5 and their locations are shown in Figure 7.6.

Residential VSRs

7.6.3           The residents of main housing estates and buildings with different heights, angles of view and distances from the Project site have been selected as representative residential VSRs. R1 to R9 are the selected representative residential VSRs who are living in low to high-rise residential developments within VE and would be potentially visually affected by the proposed Project.

7.6.4           R1, R2, R4, R8 and R9 represent the residents of low-rise village houses / residential developments with different distances from the proposed Project and different view directions of northeast (R1), northwest (R2, R8), southwest (R4) and south (R9). R3, R5, R6 and R7 represent the residents of high-rise residential developments with potential view to the proposed Project from southwest (R3 & R7), south (R5) and southeast (R6) directions.

Occupational VSRs

7.6.5           Occupants working in buildings in TPIE with different view directions have been selected as representative occupational VSRs. O1, O2 and O3 represent the occupants in TPIE with potential views from north, west and south to the Project site, respectively. The occupational VSRs who have window view to the proposed Project would be visually impacted.

Recreational VSRs

7.6.6           Visitors of golf course (V1), parks (V2 and V8), promenades (V3 and V4), hiking trails (V5, V6, V7 and V10) and multifunctional recreational facilities (V9 and V11) with different distances and angles of the view to the Project site have been selected as representative recreational VSRs.

Travelling VSRs

7.6.7           Travellers on public routes with different distances from the Project site have been selected as representative travelling VSRs. T1 is VSR within the TPIE and close to the Project site while T2 is VSR at north of TPIE and relatively distant from the Project site.

7.6.8           The sensitivity of the representative VSRs are summarized in Table 7.5 and their visual context is presented in Figure 7.7.

7.6.9           R1, R2, R4, R8 and R9 are the residents of low-rise developments and the numbers of individual are considered as medium while R3, R5, R6 and R7 are residents of high-rise developments and the numbers of individuals are considered as many. For O1 to O3, in view of the large scale of the industrial/commercial areas, the numbers of individuals are considered as many. Considering the popularity and the nature of the facilities, the numbers of individuals for V2, V3 and V4 are considered as medium while that for V1, V5 to V11 are considered as few. Considering the potential traffic and pedestrian flow of the road/street, the numbers of individuals are considered as medium for T1 and T2.

7.6.10        Most of the representative VSRs have views of plantation/harbour and their quality of existing view is considered as fair to good.  For those VSRs within TPIE, as their major view are industrial buildings/facilities and scattered roadside amenity planting, their quality of existing view is considered as poor. Alternative views are available for all representative VSRs.

7.6.11        Regarding the degree of visibility, O1 to O3 would experience full view to the proposed Project at higher level and the view of lower level would be obstructed by existing buildings and roadside plantings in the TPIE. The view to the proposed Project would be partly screened by fences / buildings / vegetation surrounding the TPSTW and partial view would be experienced by V5, V6 and T1.  For R1 to R9, V1 to V4, V7 to V11 and T2, glimpse view to the proposed Project would be anticipated due to screening by existing buildings and trees nearby.

7.6.12        The duration and frequency of view are evaluated by the nature of the VSRs. Generally, the residential VSRs are expected to have long and frequent view to the Project. On the other hand, the occupational and recreational VSRs are expected to have medium long and occasional view while the travelling VSRs are expected to have short and intermittent view to the proposed Project.

7.6.13        The sensitivity of residential VSRs are basically considered as high for their long and frequent view to the development. However, in view of the blockage of view to the Project by plantations/ buildings, the sensitivity of R1 to R9 is considered as low.

7.6.14        For occupational VSRs within the TPIE (i.e. O1 to O3), considering the poor quality of existing view, and occasional view and partial blockage of the view to the Project by existing buildings / plantation, the sensitivity of these VSRs is considered as low.

7.6.15        The sensitivity of recreational VSRs are basically considered as medium for their medium long and occasional view to the development. For V1 to V4 and V7 to V11, considering the obstructed view to the proposed Project, the sensitivity of these VSRs is considered as low.

7.6.16        For travelling VSRs, considering the short and intermittent view to the development as well as the blockage of view to the proposed Project, the sensitivity of these VSRs is considered as low.

7.7               Identification and Assessment of Landscape Impact

Potential Sources of Landscape Impact

7.7.1           This Project would upgrade the design capacity of TPSTW from 120,000 m3/day to 160,000 m3/day to meet the projected sewage treatment demand. In order to maintain normal sewage treatment services of the existing TPSTW during the construction phase, a New West Plant would be built in the proposed expansion site outside existing TPSTW boundary. After the New West Plant is fully commissioned, the existing West Plant would be partially demolished to make room for the construction of new facilities such as the sludge treatment and co-digestion works. The reconstruction works in the existing TPSTW would be split into stages to maintain adequate sludge treatment capacity throughout the construction phase. Provision of green roof and solar panel will be considered for this Project. Detailed project description and construction activities are provided in Section 2. The preliminary layout of the Project is illustrated in Figure 7.9 and the tentative dimensions of the proposed buildings and facilities within the Project site are presented Table 7.6.

7.7.2           During construction phase, potential landscape impacts would arise from removal of existing trees and construction activities including demolition of existing structures, excavation works, construction of new buildings/facilities.

7.7.3           During operational phase, potential landscape impacts would arise from presence of the new buildings and facilities of the upgraded TPSTW.

7.7.4           During planning and design of Project location, layout, design, built-form and construction method, considerations have been given to minimize the landscape impacts. As described in Section 2, more space would be required to accommodate the new co-digestion and upgraded treatment facilities. Compared with upgrading only within the existing TPSTW, utilization of the proposed expansion site, which is the preferred option, could avoid high-rise building facilities and more space could be reserved for tree planting / greenery. The heights of new buildings / facilities of this Project shall be similar to that of the surrounding existing buildings in TPIE. In addition, compact-type sewage treatment technology is proposed at the proposed expansion site to allow more space for tree planting / greenery. For the demolition works, a faster demolition method of using breakers mounted on excavator is adopted to shorten the construction period and minimize the duration of impacts associated with the construction of the Project. 

Impacts on Existing Trees

7.7.5           According to the broad brush tree survey findings, there were 530 existing trees within the proposed Project Site. According to the preliminary design, tentatively approximate 456 nos. of trees would directly conflict with the proposed works and tree removal would be unavoidably required. Regarding trees of species of conservation importance, the one individual of Aquilaria sinensis would be preserved. The ten mature trees of species Ficus microcarpa or Ficus benjamina would directly conflict with the Project and would be unavoidably removed (details refer to Appendix 7.1). Tree transplanting and/or compensatory planting shall be provided either on-site or off-site for the affected trees in accordance with DEVB TCW No. 4/2020, subject to further tree felling application. Tree Preservation and Removal Proposal (TPRP) shall be prepared in accordance with DEVB TCW No. 4/2020.

Impacts on LRs

7.7.6           Magnitude of unmitigated landscape impacts to the identified LRs are summarized in Table 7.7 while the significance of unmitigated landscape impacts on LRs are illustrated in Table 7.8.

Construction Phase

7.7.7           409 out of 483 nos. of tree within LR1.1 and all 47 nos. of tree within LR1.2 would be affected due to direct conflict with the proposed works. The Project would be fairly compatible with the urbanized/industrial environment of the existing TPSTW and proposed expansion site. As the existing trees within the Project Site would be affected, the change of landscape for LR1.1 and LR1.2 would be considered as permanent and irreversible. Considering there would be a large number of trees, including 10 mature trees, to be affected within LR1.1 and LR1.2, the magnitude of change to these LRs would be Large and the landscape impact to both LR 1.1 and LR 1.2 is expected to be Moderate / Substantial during construction phase.

7.7.8           For other LRs, as all the proposed works will be carried out within the existing TPSTW and proposed expansion site only, the magnitude of change to other LRs would be negligible and hence the significance of impact would be insubstantial.

Operational Phase

7.7.9           There would be new buildings and treatment facilities with proposed height up to 30 mPD (or about 25 m above ground) in the upgraded TPSTW. These elevated structures are fairly compatible with the existing environment of LR1.1 and LR1.2. Considering a significant decrease in the no. of trees within LR1.1 and LR1.2, the magnitude of change to these LRs would be Large and the landscape impact to both LR1.1 and LR1.2 is expected to be Moderate / Substantial  during operational phase.

7.7.10        For other LRs, as all the proposed structures would be built within the existing TPSTW and proposed expansion site only, the magnitude of change to other LRs would be negligible and hence the significance of impact would be insubstantial.

Impacts on LCAs

7.7.11        Magnitude of unmitigated landscape impact to the identified LCAs are summarized in Table 7.9 while the significance of unmitigated landscape impact on LCAs are illustrated in Table 7.10.

Construction Phase

7.7.12        As all the proposed works would not directly affect LCA 1 to LCA 3, the magnitude of change to these LCAs would be negligible and hence the significance of impact would be insubstantial.

7.7.13        The proposed demolition of existing structures and construction of new buildings and facilities would affect 13.81 ha out of 87.27 ha of the total area of LCA 4 (15.8%). As the existing trees within the Project Site would be affected, the change of landscape for LCA 4 would be considered as permanent and irreversible. The magnitude of change to LCA 4 would be Intermediate and the landscape impact is expected to be Slight/Moderate during construction phase.

Operational Phase

7.7.14        As all the proposed new buildings and facilities would not directly affect LCA 1 to LCA 3, the magnitude of change to these LCAs would be negligible and hence the significance of impact would be insubstantial.

7.7.15        There would be new buildings and treatment facilities with proposed height up to 30 mPD which is compatible with the heights of other buildings (7.1 to 71.4 mPD) within this LCA 4. These elevated structures are highly compatible with the industrial landscape of LCA 4. The magnitude of change to LCA 4 would be Small and the landscape impact is expected to be Slight during operational phase.

7.8               Identification and Assessment of Visual Impact

Potential Sources of Visual Impact

7.8.1           During construction phase, potential visual impacts would arise from construction activities including demolition of existing structures, excavation works, construction of new buildings/facilities.

7.8.2           During operational phase, potential visual impacts would arise from presence of the new buildings and facilities of the upgraded TPSTW.

7.8.3           During planning and design of Project location, layout, design, built-form and construction method, considerations have been given to minimize the visual impacts as similar to landscape impacts described in Section 7.7.

Impacts on VSRs

7.8.4           Magnitude of unmitigated visual impacts to the identified VSRs assessed based on the viewing distance, compatibility of the Project, duration of impacts, scale of works, reversibility of change and potential blockage of view are summarized in Table 7.11. The significance of unmitigated visual impacts on VSRs are illustrated in Table 7.12.

7.8.5           During construction phase, all construction works will be limited to the Project Boundary with site hoarding for the delineation and screening purposes. The existing roadside trees and some retained trees within Project Site along the perimeter will also form a natural screen and buffer during construction. The proposed construction works is fairly compatible to the existing TPSTW. The footprint of proposed Project site would be approximately 13.8 ha and scale of works is considered as intermediate. The construction works of this Project are tentatively scheduled to commence in 2025 for completion in 2036. The visual impact arising from the construction works will be temporary and reversible. Generally, the potential blockage of view by development would be negligible for most of the VSRs. However, there would be intermediate blockage of view for O1 to O3, and small blockage of view for T1 due to the construction of new buildings and structures.

7.8.6           During operational phase, the proposed new buildings and facilities will be erected within the upgraded TPSTW. The heights of the proposed building / facilities would be up to 40 mPD (or about 35 m above ground) which is comparable with that for the existing building / structures within the TPIE (7.7 to 71.4 mPD). The proposed upgraded TPSTW is considered as compatible to the surrounding industrial environment. Similar to the construction phase, the scale of works is considered as intermediate during operational phase. The visual impact arising from operation of the Project would be permanent and irreversible. However, there would be intermediate blockage of view for O1 to O3, and small blockage of view for T1 due to the presence of new buildings and structures

7.8.7           During both construction and operational phases, considering the medium / high compatibility of the Project and potential blockage of view by development, the magnitude of change to O1 to O3 and T1 would be intermediate during both construction and operational phases. In view of medium / high compatibility of the Project and negligible potential blockage of view by development, the magnitude of change to R1 to R4, R7, R8, V1 to V3, V8 to V9 and T2 would be small. Considering long viewing distance and negligible potential blockage of view by development, the magnitude of change to R5, R6, R9, V4 to V7 and V10 to V11 would be negligible during both construction and operational phases.

7.8.8           With reference to the Table 7.1, the significance of visual impacts on VSRs before mitigation measures would be Insubstantial to Slight / Moderate and the evaluations are summarized in  Table 7.12.

7.9.2           The tentative landscape master plan is presented in Figure 7.8 and location plan of proposed mitigation measures of the Project is provided in Figure 7.9. According to the preliminary design, tentatively approximate 140 nos. of trees would be transplanted/compensated within the proposed Project Site. Tree transplanting and/or compensatory planting would also be provided off-site for other affected trees subject to agreement of relevant parties. Detailed landscape and engineering design of the Project shall be undertaken during detailed design stage. 

7.10           Residual and Cumulative Impacts

7.10.1        During construction phase, good site practice (CM1) and erection of decorative screen hoarding (CM2) would reduce the landscape and visual impact arising from construction works. Tree preservation (CM3) and tree transplanting / compensatory tree planting (CM4) can minimize the landscape and visual impacts arising from tree removal.

7.10.2        During operational phase, infill planting (OM1), tree planting along site boundary (OM2) and vertical greening (OM3) can screen the new buildings and facilities as well as enhance the aesthetic quality of the upgraded TPSTW and hence reduce the landscape and visual impacts arising from the operation of the Project.

7.10.3        The residual landscape impacts on LRs and LCAs after implementation of mitigation measures proposed in Section 7.9 are illustrated in Table 7.8 and Table 7.10. For LR1.1 and LR1.2, compensatory planting for the same species of the mature trees to be felled and other trees to be felled would be provided with sufficient planting space within the Project site, nearby off-site area or other DSD¡¦s facilities. With implementation of compensatory planting for the matures trees as well as other mitigation measures described in Sections 7.10.1 and 7.10.2, the significance of residual landscape impacts on these two LRs would be reduced to moderate during construction as well as Day 1 of operation and slight during Year 10 of operation. For other LRs, the significance of residual landscape impacts would be insubstantial during construction as well as both Day 1 and Year 10 of operation. The significance of residual landscape impacts on LCAs would be reduced to insubstantial to slight during construction and insubstantial during both Day 1 and Year 10 of operation.

7.10.4        The residual visual impacts on representative VSRs after implementation of mitigation measures proposed in Section 7.9 are illustrated in Table 7.12. The significance of residual visual impacts on VSRs would be reduced to insubstantial to slight during construction as well as both Day 1 and Year 10 of operation.

7.10.5        The photomontages of proposed Project without and with mitigation measures at selected viewpoints VP1 to VP7 (i.e. R1, R3, O2, V6, T1, R9 and V1) are demonstrated in Figures 7.10 to 7.16. The locations of the viewpoints are indicated in Figure 7.6. The viewpoints used to represent different VSRs is presented in Table 7.15.

7.10.6        The proposed development would be viewed from VP1, VP3, VP4 and VP5 and screened by buildings and vegetation for VP2, VP6 and VP7.  The tree planting (OM2) along the site boundary of the Project can screen the proposed buildings and facilities. Infill planting (OM1) and green roof / vertical greening (OM3) can provide greenery to soften the industrial nature of the development as well as increase the aesthetic quality of the Project Site. Responsive design of the buildings (OM4) would blend in the proposed buildings / structures to the surrounding environment and visual context.  With proper implementation of the mitigation measures, the potential residual visual impacts arising from the proposed Project to the VSRs could be effectively reduced.

7.10.7        The potential concurrent projects are described in Section 2. With implementation of mitigation measures recommended under this Project and proposed under the separate concurrent projects.  No unacceptable cumulative landscape and visual impact would be anticipated. 

7.11           Environmental Monitoring and Audit

7.11.1        Landscape monitoring and site audit shall be carried out regularly to ensure the proper implementation of the recommended mitigation measures during construction phase and 12-month establishment period during operational phase.

7.12           Conclusion

7.12.1        Landscape and visual assessment have been conducted in accordance with Appendix K of the EIA Study Brief No. ESB-321/2019 and with reference to the criteria and guidelines as stipulated in Annex 10 and 18 of EIAO TM and EIAO Guidance Note No. 8/2010.

7.12.2        Approximately 456 nos. of trees would be unavoidably affected by the Project. The affected trees shall be transplanted in accordance with ¡§Guidelines on Tree Transplanting¡¨ issued by Development Bureau as far as possible. Any unavoidable tree felling shall be mitigated by compensatory tree planting in accordance with DEVB TCW No. 4/2020. Among the affected trees, 10 nos. of Ficus microcarpa or Ficus benjamina are mature trees with direct conflict with the proposed works and would be unavoidably removed.  Compensatory planting for the same species of the affected mature trees and other affected trees would be provided with sufficient planting space within the Project site, nearby off-site area or other DSD¡¦s facilities.

7.12.3        The most affected landscape resources would be the amenity planting in the existing TPSTW site and the proposed expansion site for the Project (LR 1.1 and LR1.2). Upon full implementation of all proposed mitigation measures, the residual impacts on all landscape baseline are anticipated to be insubstantial to moderate during construction as well as Day 1 of operation and insubstantial to slight during Year 10 of operation.

7.12.4        The most affected visual sensitive receivers would be the occupants of Tai Po Industrial Estate (O1 ¡V O3) and travellers of Dai Kwai Street (T1). Upon full implementation of all proposed mitigation measures, the residual impacts on all VSRs are anticipated to be insubstantial to slight during construction as well as both Day 1 and Year 10 of operation.   

7.12.5        It is considered the Landscape and Visual Impacts are acceptable with mitigation measures implemented during construction and operational phases.
