1. INTRODUCTION

1.1. BACKGROUND

Pursuant to the Environmental Impact Assessment Ordinance (EIAO), the Director of Environmental Protection granted the Environmental Permit (No. EP-503/2015) and Variation of Environmental Permit (No. EP-503/2015/B) to Water Supplies Department (WSD); and granted the Further Environmental Permit (No. FEP-01/503/2015/B) to AJCJV for the Contract.

The Acciona Agua, S.A. Trading, Jardine Engineering Corporation, Limited and China State Construction Engineering (Hong Kong) Limited As AJC Joint Venture (AJCJV) is contracted by WSD to carry out the Design, Build and Operate First Stage of Tseung Kwan O Desalination Plant (DPTKO) under Contract No. 13/WSD/17 (“the Contract”). The Further Environmental Permit (No. FEP- 01/503/2015/B) to AJCJV to construct the designation contract.

Acuity Sustainability Consulting Limited (ASCL) is commissioned by AJCJV to undertake the Environmental Team (ET) services as required and/or implied, both explicitly and implicitly, in the Environmental Permit (EP), Environmental Impact Assessment Report (EIA Report) (Register No.

AEIAR-192/2015) and Environmental Monitoring and Audit Manual (EM&A Manual) for the Contract;

and to carry out the Environmental Monitoring and Audit (EM&A) programme in fulfillment of the EIA Report’s EM&A requirements and Contract No. 13/WSD/17 Specification requirements.

Before WSD taking over the area for DPTKO development, the construction and demolition (C&D) materials being stockpiled and grown vegetation had been removed for construction projects. Prior to being handed over the area for DPTKO development, the area for the proposed desalination plant had been cleared of the stockpiled C&D materials and grown vegetation. It was then handed over to WSD when the finished ground level reached +5.2mPD.

In 2017, design variations of Contract were proposed, the design variations in relation to landscape and visual impacts are mainly the changes in Contract layouts, which includes; the relocation of building blocks with increase in building height within the original earmarked site defined in the EIA report; the reduction of the site area for desalination plant and; the reduction of slope mitigation works inside the Clear Water Bay Country Park (CWBCP). In 2025, design variations in relation to the reduction of slope mitigation works were further proposed to alleviate the high construction risk after frequent landslides.

The change in magnitude of landscape and visual impacts of the design variations from the EIA report have been thoroughly assessed and discussed in the Environmental Review Report (ERR) prepared by Black & Veatch (now known as Binnies HK Ltd.) on 03 November 2017. The ERR has concluded that the revised Contract layout will not change the overall landscape and visual impact levels presented in the EIA Report with mitigation measures in place. No additional mitigation measures are considered required for the proposed Contract variations. The environmental outcome from landscape and visual perspectives anticipated in the EIA Report will remain valid and applicable to the latest design.

1.2. CONTRACT DESCRIPTION

Freshwater Main Alignment (undertaken by Contract No. 13/WSD/16) A dedicated trunk feed system including about 9 km long water mains for the transfer of freshwater output from the desalination plant to the existing Tseung Kwan O Fresh Water Primary Service Reservoir in Po Lam.

1.3. PURPOSE OF THE PLAN

According to Condition 2.11 of the FEP and EP-503/2015/B, a landscape and visual mitigation proposal shall be submitted to the Director of Environmental Protection for approval no later than 1 month before the commencement of construction of the desalination plant of the Contract. The proposal, with drawings in the scale of 1:1000 or other appropriate scales as agreed by the Director, shall show the landscape and visual mitigation measures of the Contract, and shall include at least the following information:

(1) aesthetic landscape and architectural treatment for above ground structures;

(2) tree felling and preservation proposal showing quantity, plant species, location(s) and size of trees to be retained/transplanted/felled/compensated, and location(s) of transplanted trees;

(3) Landscape Plan showing location(s) of greening works including green roofs, roadside planting, vertical greening, screen planting, amenity planting, edge treatment along boundary and any other landscape enhancement to mitigate landscape impact of the Contract.

The scope of this LVMP covers the landscape and visual mitigation measures under Contract No.

13/WSD/17. The site layout plan for Contract No. 13/WSD/17 is shown in Appendix A. Before submission to the Director, the Landscape and Visual Mitigation Proposal shall be certified by the Environmental Team (ET) Leader and verified by the Independent Environmental Checker (IEC) as conforming to the requirements and recommendations contained in the EIA Report (Register No.

AEIAR-192/2015), EP/FEP and ERR. All measures recommended in the approved Proposal shall be fully and properly implemented and maintained for the Contract.

1.4. UPDATE OF THE PLAN

In accordance with EP Condition 2.7, the Updated Vegetation Survey for Slope Mitigation Works (Issue 212‑2) was submitted on 24 July 2017 and subsequently approved by the EPD on 31 August 2017 (hereinafter referred to as the “2017 Vegetation Survey”). The 2017 Vegetation Survey Report documented the survey findings, assessed the potential impacts, if any, arising from the proposed slope mitigation works, and recommended appropriate protection and mitigation measures for plant species of conservation importance identified during the 2016 survey. A revised report was later prepared to update the 2017 Vegetation Survey by incorporating the findings of subsequent vegetation surveys conducted in 2020, 2021, and 2023 (hereinafter referred to as the “2026 Vegetation Survey”). The 2026 Vegetation Survey was submitted to EPD on 12 February 2026 and subsequently approved on 9 March 2026.

In accordance with EP Condition 2.8, the Detailed Design Plan for Slope Mitigation Works (Issue 214‑2) was submitted on 2 March 2018 and subsequently approved by the EPD on 20 April 2018 (hereinafter referred to as the “2018 DDP”). The 2018 DDP detailed the proposed slope mitigation works, including the installation of a flexible barrier, rock slope stabilisation works, boulder removal, and boulder break‑off.

A series of extreme weather events subsequently occurred in Hong Kong, including a 1‑in‑500‑year black rainstorm and Typhoons Saola and Koinu in September and October 2023, as well as an amber rainstorm in May 2024. These events triggered multiple landslides within the slope area located in Clear Water Bay Country Park. Following a review of the severity and frequency of the landslides in the relevant slope area in consultation with the Civil Engineering and Development Department (CEDD), and taking into account the low usage frequency and low risk to life and property at the slope toe area, the extent and arrangement of the slope mitigation works within Clear Water Bay Country Park were re‑examined. A reduced extent and revised arrangement of slope mitigation works were subsequently proposed to the Geotechnical Engineering Office (GEO) / CEDD. GEO/CEDD provided no further comments on the design of the slope mitigation works in its memorandum dated 4 March 2025 (Ref.: ( ) in ME‑30‑2025‑12‑226‑1). In accordance with EP Condition 2.8, the Detailed Design Plan for Slope Mitigation Works was updated to reflect the revised slope mitigation works design.

The updated Detailed Design Plan was subsequently approved by EPD on 22 June 2026 (hereinafter referred to as the “2026 DDP”).

The 2018 DDP presented the initial tree survey results within the project area, and the slope mitigation works area, which were conducted by WSD in November 2015 and March 2016. CEDD carried out an extensive tree felling exercise in 2018 in accordance with their approved tree felling application (LandsD’s approval memorandum ref. (30) in LM 2 to DLO/SK 651/SGS/59 Pt.6 dated 23 October 2018), prior to site handover to WSD in December 2019. Upon handover of the site in December 2019, tree surveys were conducted within the desalination plant site and along the temporary access for boulder removal and stabilisation by break-off works in February and August 2020 to establish a new baseline record of the existing trees by WSD following site handover. After the February and August 2020 tree surveys, it was identified that certain trees had not been felled by CEDD in accordance with CEDD’s approved tree felling application. Consequently, CEDD conducted additional tree felling operations in accordance with their approved application to remove those trees originally proposed for felling. In the subsequent period, the site was affected by typhoons and adverse weather conditions. As a result, prior to the commencement of the slope mitigation works, another series of tree surveys was carried out by WSD in February, May, and June 2022, and February 2023 within the desalination plant site, the areas for rock slope stabilisation works, the area for the proposed flexible barrier, and along the temporary access for boulder removal and stabilisation by break-off works. The 2026 DDP presents updated information based on the tree surveys carried out in February and August 2020, February, May and June 2022, and February 2023.

In accordance with EP Condition 2.10, the Landscape and Visual Mitigation Proposal (Rev. 7) was submitted on 1 March 2024 and subsequently approved by EPD on 8 March 2024 (hereinafter referred to as the “2024 LVMP”). Section 3.4 of the approved LVMP presents details of the slope mitigation works and the corresponding landscape and visual mitigation measures based on the information provided in the 2017 Vegetation Survey and the 2018 DDP.

This report aims to update the following information in accordance with the 2026 Vegetation Survey and 2026 DDP, and the refinement of the proposed site layout design in Section 3.2:

• Revision of slope mitigation works in accordance with 2026 DDP;

• Revision of landscape and visual mitigation measures for slope mitigation works with respect to the revised slope mitigation works; and •

Revision of tree survey results and the corresponding compensatory planting proposal in accordance with 2026 DDP

• A uniform setback of approximately 15 m from the project boundary was considered during the design process. Achieving such a setback would require a more compact and vertically stacked arrangement of treatment facilities, resulting in increased pumping requirements, higher energy consumption, reduced hydraulic efficiency, and greater lifecycle costs and environmental impacts over the plant's 50-year design life. This was one of the key considerations in the refinement of the proposed site layout. The proposed non-uniform setback reflects the operational, fire safety, and sustainability requirements of the

desalination plant. In particular, Workshop Y is located adjacent to the site boundary to provide operational efficiency and allows shared use with future desalination facilities .

Together with the provision of natural buffering and integrated landscape and visual mitigation measures, the design achieves the intent of the setback requirements while maintaining acceptable landscape and visual impacts. Section 3.2 has also been updated to reflect the actual site conditions.

2. PROPOSED LANDSCAPE AND VISUAL MITIGATION MEASURES

Section 11.10.3 of the approved EIA Report and Annex A of the EM&A Manual recommended the following mitigation measures. Explanations of how the measures are fulfilled are given in Table 2.1 and subsequent sections. Implementation details of mitigation measures under the Contract and the implementation schedule are described in Table 2.1 and subsequent sections. In compliance with Clause No. 2.11(iii) of the EP, Appendix C illustrates the layout of the landscape plan for the proposed greening works and landscape enhancement measures, with reference to MM3 and MM6 only. MM5 is not included in Appendix C, as the flexible barriers have been redesigned and relocated away from the slope toe of the Clear Water Bay Country Park, thereby eliminating the need for above‑ground works or soil nailing and avoiding any tree felling. Other landscape‑related mitigation measures are design requirements or measures to be implemented during the construction phase, and are therefore not shown in Appendix C.

3. AESTHETIC LANDSCAPE AND ARCHITECTURAL TREATMENT FOR ABOVE GROUND

STRUCTURES

3.1. MINIMIZATION OF CONSTRUCTION AREA AND AREA FOR TEMPORARY ABOVE GROUND

STRUCTURES (MM1)

The construction site is limited to the contract area allowed in the EP. The dimension of the DPTKO is around 500m long and 180m wide.

3.2. MINIMIZATION OF ABOVE GROUND STRUCTURES (MM2)

The site for the desalination plant is essentially a linear site and is oriented North West – South East along the longer side (Appendix A).

The design adopts a fragmented building layout that responds to the existing topography and surrounding natural landscape. Landscape buffering measures are incorporated to soften the interface between built structures and the natural environment, while building heights are minimised to reduce visual prominence. With these design strategies, the residual landscape and visual impacts are considered acceptable, notwithstanding the non-uniform setback arrangement.

The proposed structures do not exceed 35 m above future ground level. The majority of the buildings are one- to two-storey structures accommodating process facilities and building services. The Administration Building is the only exception, comprising five storeys with an approximate height of 33 m. The layout plan and sectional elevations of the DPTKO are presented in Appendix D.

Heights of all buildings do not exceed 35m above the future ground level. The roof level over the lift machine room of the Administration Building, the highest building for DPTKO, is +39.975mPD, about 33m above the ground level of +6.65mPD.

The entire development contains two types of buildings – desalination process plants and ancillary buildings. Following the flow of operational layout, the desalination process plant is separated into 4 treatment zones, namely Intake & Outfall Zone (Combined Shaft), Pre-treatment Zone (ActiDAFF), Reverse Osmosis Processing Zone (Reverse Osmosis Building) and Post-Treatment Zone (Post- Treatment Building). They span from southeast seashore toward the northwest side of the site.

Processed water will be gone through the final treatment process in the Product Water Storage Tank before fed to the TKO fresh water primary service reservoir.

The elongated site is enveloped by the richly vegetated Tin Ha Shan on the east and faces the sea (Tai Miu Wan) on the southeast. To integrate, blend, and connect/align the design with these surrounding natural environments, DPTKO is divided into 15 building blocks, dispersed around the site to avoid putting a large, single, disproportionate building mass on the site.

3.3. AESTHETIC LANDSCAPE AND ARCHITECTURAL TREATMENT FOR ABOVE GROUND STRUCTURES

(MM3)

The aesthetic landscape and architectural treatment of the site are designed to respond to occupational, recreational, and travelling sensitive receivers including the residents in the nearby Tseung Kwan O residential developments. The site has a high proportion of soft landscape (including at-grade greening, roof greening, and vertical greening), and numerous landscape areas are provided at various location of the site. The use of local species for both ornamental and boundary buffer facilitate the attainment of not less than 30% of landscape coverage areas to be planted with local plant species. These soft landscape designs provide a pleasant visual environment for the neighbouring communities is to create a successful destination with attractive external environment for the enjoyment of future visitors/ users. The soft landscape design of the DPTKO is shown in the Appendix E.

The key aesthetic landscape (soft landscape) includes the following;

1. Green Roofs

2. Roadside Planting

3. Vertical Greening

4. Screening planting along the site

4. Landscape Areas

3.3.1. GREEN ROOF

Six nos. of buildings, namely, Administration Building, Chemical Building, Reverse Osmosis & Electrical Building, Post-treatment Building, On-site Chlorine Generation System Building and CO2 Tanks Area, and Workshop are designed with green roof as showed in Appendix E. Groundcover will be the main vegetation provided in green roofs, the planting schedule and the proposed planting pattern for green roofs showed in Appendix E. The idea of the soft landscape design is to provide an extensive greening with low maintenance. The avoidance of tall shrubs and trees, especially near the PV panels which is situated in building Reverse Osmosis and Electrical Building are the concern not to block the normal operation of the PV panels.

3.3.2. ROADSIDE PLANTING

Apart from the undisturbed slopes in the periphery, the design incorporates roadside planting verges for ornamental trees, shrubs and groundcovers along the internal vehicular road. This will help provide shade while enhancing the visual amenity to the road users for visitors to the site. The proposed planting location and planting schedule are shown in Appendix E.

3.3.3. VERTICAL GREENING

7 no. of building, namely, Administration Building, Reverse Osmosis Building, Main Electrical and Chiller Plant Building, ACTIDAFF, Product Waters Storage Tank and Post-treatment Building and Combined Shaft Building are designed with vertical greening. Due to the nature of the industrial site, features of climbers on a vertical fence of 1.5m/ 3.5m high are proposed along its east and west boundary. Along the northern edge abut to WSD reserve, 2.5m high wire mesh fence with vertical green is proposed. A 3.5m high fence wall with vertical green is also proposed to the west of the Site.

Stainless steel wire and rope will be installed on wall and will act as the training system for the proposed climbing plant. The proposed planting location and species list are shown in Appendix E.

3.3.4. SCREENING PLANTING ALONG THE SITE

A 1.5m setback of fence at the main entrance is provided. In this setback zone, low shrubs and groundcover at a wavy pattern (Appendix E) is also provided to enhance the first impression of this particular Contract.

The establishment of functional tree belts to ameliorate external environmental effects such as noise, dust and unpleasant views is important consideration for this site – since it will be surrounded by roads with industrial heavy vehicles.

In addition to the aesthetic considerations the proposed trees, shrubs and groundcover planting will perform a number of functional roles. This will also provide a physical barrier between the hillside environment outside the site boundary and the areas inside the grounds of the facility, particular those adjacent to the main building blocks.

The plantation of heavy standard trees is extensively proposed on site as shown Appendix E. This will realize multiple environmental benefits including the provision of shade. Apart from the physical screening, the green buffer also functions as a noise barrier psychologically.

3.3.5. LANDSCAPE AREAS

Numerous landscape areas are provided at various locations such as, Main Entrance, Drop-off Plaza, Main Plaza, Landscape Plaza, Rain Garden, Courtyard area in Administration Building. Landscape designs at these locations are showed in Appendix E.

3.3.6. AESTHETIC TREATMENT OF ALL STRUCTURES

The siting and configuration of the DPTKO is designed to achieve a coherent suburban development consistent with the planning vision for TKO, and to create a compatible visual identity with the surrounding especially the adjacent Country Park (Clear Water Bay). The visual identity will focus on vigour and liveliness of TKO by identifying a family of façade materials, visual permeability at waterfront, matching of colour schemes, and fenestration control. The intervention of this contract activates the neighbourhood, inviting people to appreciate the built environment in the suburban distract.

The architectural design theme is a linear interpretation of water wave in macroscopical scale, which enhance/blend in with the surrounding environment and promote the green image of DPTKO. As “water” is the essence of the desalination plant, the character of water will be expressed throughout the design. The proposed construction materials and surface finishes will enhance/ blend in with the surrounding environment.

The key aesthetic treatment (hard landscape) includes the following;

1. Fairface concrete finishing for building structures;

2. Prefabricated fairface concrete façade cladding for building structures;

3. Paving materials of grey-tone colors in random mix as main floor finishes;

4. Permeable perimeter fence;

5. Architectural feature fins

3.3.7. FAIRFACE FINISHING

The buildings of DPTKO primarily use reinforced concrete with fairface concrete finish. The roofs are green or paved with light-colour materials and installed with solar panels. For the Administration Building, full-height glazing is designed to face north to maximise and diffuse natural light.

External façade deliberately uses fairface concrete as finish. The light grey colour of fairface concrete is a mixture of the natural colour of its ingredients, including aggregates, sand and cement. It is a neutral colour that blend in with other building materials and natural vegetation superbly. Architects world-wide are fond of using fairface concrete, to create creative identity to their buildings. With the combination of fairface concrete softened by vertical greening, the buildings blend into the surroundings, minimising the visual impact to both the neighbourhood and building users.

Some of the water storage tank and ancillary buildings will be appeared in traditional on-site cast fairfaced concrete façade. To enrich the façade and reduce the dullness along the site, texture paint finish is introduced to the buildings to echo with the rhythmic pattern for the DfMA façade building.

3.3.8. PREFABRICATED FAIRFACE CONCRETE FAÇADE CLADDING

Prefabricated fairface concrete façade cladding through DfMA system would be adopted for five buildings: ActiDAFF (a building in Pre-treatment Zone), Reverse Osmosis Building & Electrical Building, Post-Treatment Building, On-Site Chlorine Generation System Building and Product Water Storage Tank & Electrical Building. Typical building elevation with prefabricated fairface concrete

cladding and colors selected for the facade panels are shown in Appendix F. Arrangement of DfMA façade on these buildings is shown in Appendix F.

3.3.9. PAVING MATERIALS

Paving materials (mainly Paving Blocks) shall be hard wearing, durable and of low maintenance.

Concrete paver in grey tone (dark grey, light grey, and brown) mix in a random manner will be employed as the main floor finishes for the pavement, the material schedule and paving module plan are as shown in Appendix F.

3.3.10. PERMEABLE PERIMETER FENCE

Two area of the fence will adopt permeable perimeter fence to capture sea breeze, the linear arrangement of the building blocks creates “cooling corridors” in the complex by facilitating air flow and maximising natural breezes during summer. This corridor cooling effect helps create more effective cross ventilations and avoid heat accumulation in the summer days. The design details are shown in Appendix F.

3.3.11. ARCHITECTURAL FEATURE FINS

Architectural feature fins with blue color tone at ActiDAFF Building Shades of blue color tones were adopted along the visitors’ route. The selected colors will be applied to water pipes, GRP covers and architectural fins, to enrich the grey color of the fairface concrete. Most of the architectural fins articulated to form a wavy form in representing the relationship of the desalination plant and the sea.

The rendering of feature fins is shown in Appendix F.

3.4. SLOPE MITIGATION WORKS (MM6)

The Detailed Design Plan Slope Mitigation Works submitted under EP Condition 2.8 have recommended protection/ mitigation measures to be implemented on site during the construction stage of this Project. All recommended protection/ mitigation measures shall be fully and properly implemented. No site clearance works for slope mitigation works of this Project shall be allowed prior to the completion of such protection/ mitigation works on site. The key slope mitigation measures are summarised below and present in Appendix H:

Flexible Barrier

The flexible barriers will be located away from the slope toe of the Clear Water Bay Country Park (CWBCP). All above-ground elements of the flexible barrier are all located outside the CWBCP.

Inclined underground anchors, installed 3-4m into rock, are required and may extend into CWBCP boundary. The maximum length of the underground anchors shall be 15m. No ecological impact on plant species of conservation importance and trees anticipated as inclined anchors would be installed into bedrock situated 3-4m below the ground level.

Rock Slope Stabilisation/ Improvement Works

Rock stabilisation works will be adjusted to ensure that no tree will be felled, and no plant species of conservation importance are affected. The anchorage for the temporary working platform and access routes will be designed to avoid the plant species of conservation importance.

Slope mitigation works have been adjusted to suit the existing slope conditions, including 180m2 of wire mesh, 37 nos. of rock dowels, 5 nos. of buttress and flexible barrier along the slope toe. To reinstate vegetation loss and disturbance resulting from slope stabilisation works, hydroseeding and planting of grasses and shrub seedlings undertaken at the flexible barriers which will locate at the ground level adjacent to the existing slope toe. Regular monitoring and appropriate maintenance works to be carried out for a 12-month establishment period to ensure successful vegetation recovery, green effect and diversity.

As stated in the detailed design plan for the slope mitigation works, the design of the buttress wall and the requirement for tree rings were to be confirmed following rock mapping and assessment of the specific site conditions. Upon completion of the rock mapping and site surveys, it has been verified that the proposed buttress walls are aligned with sufficient spatial separation from all existing trees. This clearance ensures that tree roots, natural growth, and trunk movement will not interfere with, or impose any load on, the wall structure.

Tree rings are normally required when structural elements are located close to trees and may encroach upon the root zone or trunk. As the buttress walls have been intentionally designed with adequate spatial separation with the existing trees, no physical conflict between the existing trees and buttress walls is expected. The protective function typically provided by tree rings is therefore inherently achieved through the spatial separation, and additional tree rings would not offer further benefit.

The adopted design provides both structural safety and protection of existing trees without the need of tree rings. In addition, stone facing has been applied to the buttress walls to reinstate the natural appearance of the slope, and the wire mesh on the rock face has been detailed with openings at tree locations to avoid obstruction.

Boulder Removal/ Break-off

There are 6 nos. of unstable boulders will be removed and 4 nos. of boulders to be break-off. A temporary working platform and a minimum access clearance of 600 mm around each boulder will be provided for the proposed boulder removal/break‑off works. To avoid direct conflict between the boulder removal and nearby plant species of conservation importance, protection zones/ works exclusion zones will be established at least 1.5 m radius from the identified plant species of conservation importance to preserve them on site.

The protection zones/ works exclusion zones will be established prior to site clearance and throughout the construction period to separate the identified protected plant individuals from the works.

The temporary working platform and temporary access will be designed to avoid anchorage on the plant species of conservation importance.

Detailed design of the slope mitigation measures at Clear Water Bay Country Park could be referred to Appendix H and Detailed Design Plan for Slope Mitigation Works.

3.5. LIGHTING ARRANGEMENT (MM8)

3.5.1. GENERAL

All lights provided in the construction site or the proposed desalination plant should have the following features to minimize light spill outside the contract area:

• The number of lighting should be kept minimum;

• The lux level should be designed just sufficient for safety purpose;

• Point light towards the Site to minimize light spill outside the contract boundary;

• Shielded with hood to prevent sky glow;

• High mounting light will have less spill light and glare;

• Aim light no greater than 70º;

Reference: Guidance Note 01/20 Guidance Notes for the Reduction of Obtrusive Light •

Where light has to be pointed upward, adjust the light direction to ensure no spillage outside the target.

Reference: Guidance Note 01/20 Guidance Notes for the Reduction of Obtrusive Light

3.5.2. GARDEN LIGHTS IN OPERATION PHASE

The outdoor landscape lighting system is crafted with LED bollard lighting along the pathway and spotlight implants to the landscape area will light up the entire garden at night-time that creates a fascinating foreground focal area. Bollard light with low lux level just enough for illuminating the garden will be adopted. The light will be diffused without pointing in one direction. The proposed lighting plan can be found in Appendix G.

4. TREE FELLING AND PRESERVATION PROPOSAL (MM4)

As described in Section 1, the project site for the proposed desalination plant was cleared of stockpiled C&D materials and vegetation by CEDD prior to site handover. Tree felling was carried out by CEDD in accordance with its approved tree‑felling application (LandsD approval memorandum ref. (30) in LM 2 to DLO/SK 651/SGS/59 Pt.6 dated 23 October 2018), and the site was handed over to WSD in December 2019. Following site handover, tree surveys were conducted in February and August 2020 within the DPTKO area and along the temporary access for boulder removal and stabilisation by break-off works to establish the baseline tree condition. LVMP Revision 7 presented the survey results for the DPTKO area only, while trees surveyed along the temporary access were not included.

The 2020 tree surveys identified that some trees originally proposed for felling under CEDD’s approved tree‑felling application had not been removed. These trees were subsequently felled by CEDD in 2020. In addition, the site was affected by typhoons and adverse weather conditions in the subsequent period. To confirm the updated baseline tree condition prior to commencement of construction works, further tree surveys were carried out in February, May and June 2022, and February 2023, covering the DPTKO area as well as the tree survey areas for rock slope stabilisation works, flexible barriers, and the temporary access for boulder removal and stabilisation by break-off works. LVMP Revision 8 updated the number of existing trees based on the available tree survey results but was limited to the DPTKO area. LVMP Revision 9 consolidates all tree survey data and presents a complete and up‑to‑date baseline tree inventory covering all project‑related works areas.

The LVMP was updated progressively to reflect changes in site conditions arising from additional tree felling works carried out by CEDD, tree impacts from adverse weather events, and the availability of updated tree survey data prior to commencement of construction works. LVMP Revision 9 was prepared to consolidate all available tree survey results and to ensure that the baseline tree inventory fully covers all project‑related works areas, including DPTKO, rock slope stabilisation works, flexible barriers, and temporary access areas. This update was necessary to ensure accuracy, completeness, and compliance with prevailing EIA and LVMP requirements.

According to the tree surveys conducted in February and August 2020, February, May and June 2022, and February 2023, a total of 148 trees were recorded within the study area. Of these, three trees were located within the DPTKO area, while 145 trees were recorded within the tree survey areas for rock slope stabilisation works, flexible barriers, and along the temporary access for boulder removal and stabilisation by break-off works. All 148 trees were originally proposed for retention.

Following completion of the tree surveys, the site was affected by typhoons and adverse weather conditions, resulting in the collapse or loss of nine trees (i.e. T030, T031, T058, T059, T124, T128, T207, T216 and T217). Accordingly, a total of 139 existing trees are proposed for retention. The tree survey results are presented in Table 4.1 and Appendix B, while the tree treatment summary is provided in Table 4.2.

5. CONSTRUCTION MITIGATION MEASURES

Located in the public filling area, the site is not visually attractive and looks similar to a construction site. Nevertheless, landscape and visual mitigation measures in construction phase are recommended as below:

5.1. BLENDING IN WITH THE EXISTING LANDSCAPE AND VISUAL

• Construction area and works shall be minimized to prevent affecting nearby landscape environment;

• Area of temporary structures, such as the contractor’s office, shall be minimized to a practical minimum and located at less visual prominent locations.

• Decorative hoarding with appropriate colours compatible with the surrounding area shall be erected around all works areas to minimize the visual impacts;

• Avoid potential impact on existing coastline and seashore

5.2. PROVIDING SOFT LANDSCAPING

• Exposed area and soil stockpiles shall be hydroseeded or covered with visually unobtrusive materials/ tarpaulins;

• Green roofs shall be considered on site office where possible;

• Commence landscape planting at locations where construction work has been completed.

5.3. CONSERVING/RECOVERING EXISTING GREENERY

• Existing trees near the Contract Boundary and slope mitigation work areas, and retained trees within site boundary shall be carefully protected. Detailed Tree Protection Specification shall be followed;

• The Contractor shall include a detailed working method statement for the protection of trees prior to conducting any works next to all retained trees;

• Trees unavoidably affected by the works shall be transplanted where practicable. Where possible, trees should be transplanted direct to permanent locations rather than temporary holding nurseries.

5.4. IMPLEMENTING GOOD SITE PRACTICES/ OTHER RECOMMENDED MITIGATION MEASURES

• Sufficient drainage system shall be provided to control run-off from entering the sea;

• All night-time lighting will be reduced to a practical minimum both in terms of number of units and lux level and will be hooded and directional (See Sec.3.4).

5.5. CONDUCTING REGULAR SITE AUDIT

• Site inspection shall be undertaken regularly to ensure mitigation measures are being effectively implemented;

• Coordinate implementation programme with concurrent contract, if any, to minimize potential cumulative impacts and where possible reduce the period of disturbance to visual context.

6. CONCLUSION

The landscape and visual mitigation measures to be implemented under Contract No. 13/WSD/17 have complied with the requirements and recommendations contained in the EIA Report (Register No. AEIAR-192/2015), the EP, the FEP and ERR. All measures recommended in this LVMP will be fully and properly implemented and maintained for the Contract.
