10.2.1.2 The OZP gazetted under the Town Planning Ordinance provides the statutory framework for land use development. Reference has been made to the Approved Ma On Shan OZP No. S/MOS/22 (15.1.2016) and the Approved Sha Tin OZP No. S/ST/32 (11.12.2015).

· Identification of the baseline landscape resources (LRs) and landscape characters found within the study area. This is achieved by site visits and desktop study of topographical maps, information databases and photographs.

· Assessment of the degree of sensitivity of the LRs and landscape character areas (LCAs). This is influenced by a number of factors including whether the resource/character is common or rare, whether it is considered to be of local, regional, national or global importance, whether there are any statutory or regulatory limitations/requirements relating to the resource, the quality of the resource/character, the maturity of the resource and the ability of the resource/character to accommodate change.

· The sensitivity of each landscape feature and character area is classified as follows:

High:	Important landscape character or resource of particularly distinctive character or high importance, sensitive to relatively small change.
Medium:	Landscape character or resource of moderately valued landscape characteristics reasonably tolerant to change.
Low:	Landscape character or resource, the nature of which is largely tolerant to change.

· Identification of potential sources of landscape changes. These are the various elements of the construction works and operation procedures that would generate landscape impacts.

· The magnitude of landscape changes is classified as follows:

Large:	The landscape character or landscape resource would incur a major change.
Intermediate:	The landscape character or landscape resource would incur a moderate change.
Small:	The landscape or landscape resource would incur slight or barely perceptible change.
Negligible:	The landscape or landscape resource would incur no discernible change.

· Identification of potential landscape mitigation measures. These may take the form of adopting basic engineering design to prevent and/or minimise adverse landscape impacts before adopting other mitigation or compensatory measures to alleviate the impacts. Potential mitigation measures shall also include the preservation of vegetation and natural landscape resources, transplanting trees in good condition and value, provision of screen planting, re-vegetation of disturbed lands, compensatory planting, woodland restoration, aesthetic design of aboveground structures including provision of finishes, colour scheme, texture of materials used and any measures to mitigate the impact on the existing and planned land use and visually sensitive receivers (VSRs). A programme for the mitigation measures is provided. The agencies responsible for the funding, implementation, management and maintenance of the mitigation measures are identified.

· Prediction of the significance of landscape impacts before and after the implementation of the mitigation measures. By synthesizing the magnitude of the various impacts and the sensitivity of the various landscape resources, it is possible to categorise impacts in a logical, well-reasoned and consistent fashion. Table 10.1 shows the rationale for dividing the degree of significance into four thresholds, namely insubstantial, slight, moderate, and substantial, depending on the combination of a negligible-small-intermediate-large magnitude of change and a low-medium-high degree of sensitivity of landscape resource /character.

Table 10.1 Relationship between Landscape Sensitivity and Magnitude of Change in Defining Impact Significance

Magnitude of Change	Large	Moderate	Moderate / Substantial	Substantial
	Intermediate	Slight / Moderate	Moderate	Moderate / Substantial
	Small	Insubstantial / Slight	Slight / Moderate	Moderate
	Negligible	Insubstantial	Insubstantial	Insubstantial
		Low	Medium	High
		Sensitivity of Landscape Character Area and Resource
Note: All impacts are Adverse unless otherwise noted with Beneficial.

· The significance of landscape impacts is categorised as follows:

Substantial:	Adverse / beneficial impact where the proposal would cause significant deterioration or improvement in existing landscape quality.
Moderate:	Adverse / beneficial impact where the proposal would cause a noticeable deterioration or improvement in existing landscape quality.
Slight:	Adverse / beneficial impact where the proposal would cause a barely perceptible deterioration or improvement in existing landscape quality.
Insubstantial:	No discernible change in the existing landscape quality.

· Prediction of Acceptability of Impacts. An overall assessment of the acceptability, or otherwise, of the impacts according to the five criteria set out in Annex 10 of the EIAO-TM.

10.3.2 Visual Impact Assessment Methodology

10.3.2.1 The visual impacts have been assessed according to the following procedures.

· Identification of the Visual Envelope during the construction and operation phases of the project. This is achieved by site visit and desktop study of topographic maps, photographs and preparation of cross-sections to determine visibility of the Project from various locations.

· Identification of the VSRs within the Visual Envelope at construction and operation phases. These are the people who would reside within, work within, play within, or travel through, the Visual Envelope.

· Assessment of the degree of sensitivity of the VSRs. Factors considered include:

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

o other factors which are considered (as required by EIAO GN 8/2010) include the value and quality of existing views, the availability and amenity of alternative views, the duration or frequency of view, and the degree of visibility.

· The sensitivity of VSRs is classified as follows:

High:	The VSR is highly sensitive to any change in their viewing experience.
Medium:	The VSR is moderately sensitive to any change in their viewing experience.
Low:	The VSR is only slightly sensitive to any change in their viewing experience.

· Identification of relative numbers of VSRs. This is expressed in terms of whether there are “many“, “medium” and “few” VSRs in any one category of VSR.

· Identification of potential sources of visual changes. These are the various elements of the construction works and operation that would generate visual changes.

· Assessment of the potential magnitude of visual changes. Factors considered include:

o the compatibility with the surrounding landscape;

o the duration of the impact;

o the reversibility of the impact;

o the scale of the impact and distance of the source of impact from the viewer; and

o the degree of visibility of the impact, and the degree of which the impact dominates the field of vision of the viewer.

· The magnitude of visual changes is classified as follows:

Large:	The VSRs would suffer a major change in their viewing experience.
Intermediate:	The VSRs would suffer a moderate change in their viewing experience.
Small:	The VSRs would suffer a small change in their viewing experience.
Negligible:	The VSRs would suffer no discernible change in their viewing experience.

· Identification of potential landscape mitigation measures. These may take the form of adopting basic engineering design to prevent and/or minimise adverse visual impacts before adopting other mitigation or compensatory measures to alleviate the impacts. Potential mitigation measures shall also include the preservation of vegetation and natural landscape resources, provision of screen planting, re-vegetation of disturbed lands, compensatory planting, woodland restoration, aesthetic design of aboveground structures including provision of finishes, colour scheme, texture of materials used and any measures to mitigate the impact on the existing and planned land use and VSRs. A programme for the mitigation measures is provided. The agencies responsible for the funding, implementation, management and maintenance of the mitigation measures are identified.

· Prediction of the significance of visual impacts before and after the implementation of the mitigation measures. By synthesizing the magnitude of the various visual impacts and the sensitivity of the VSRs, and the numbers of VSRs that are affected, it is possible to categorise the degree of significance of the impacts in a logical, well-reasoned and consistent fashion. Table 10.2 shows the rationale for dividing the degree of significance into four thresholds, namely, insubstantial, slight, moderate and substantial, depending on the combination of a negligible-small-intermediate-large magnitude of change and a low-medium-high degree of sensitivity of VSRs.

Table 10.2 Relationship between VSRs Sensitivity and Magnitude of Change in Defining Impact Significance

Magnitude of Change	Large	Moderate	Moderate / Substantial	Substantial
	Intermediate	Slight / Moderate	Moderate	Moderate / Substantial
	Small	Insubstantial / Slight	Slight / Moderate	Moderate
	Negligible	Insubstantial	Insubstantial	Insubstantial
		Low	Medium	High
		Sensitivity of VSRs
Note: All impacts are Adverse unless otherwise noted with Beneficial.

· The significance of visual impacts is categorised as follows:

Substantial:	Adverse / beneficial impact where the proposal would cause significant deterioration or improvement in existing visual quality.
Moderate:	Adverse / beneficial impact where the proposal would cause a noticeable deterioration or improvement in existing visual quality.
Slight:	Adverse / beneficial impact where the proposal would cause a barely perceptible deterioration or improvement in existing visual quality.
Insubstantial:	No discernible change in the existing visual quality.

· Prediction of Acceptability of Impacts. An overall assessment of the acceptability, or otherwise, of the impacts according to the five criteria set out in Annex 10 of the EIAO-TM.

10.4 Review of Planning and Development Control Framework

10.4.1.1 Relevant plan(s) and/or studies which may identify areas of high landscape value, country parks, coastal protection area, GB and CA designations are reviewed. Any guidelines on landscape and urban design strategies and frameworks that may affect the appreciation of the Project are also reviewed. The aim is to gain an insight of the future outlook of the affected area so as to assess whether the Project can fit into the surrounding setting. Any conflict with statutory town plan(s) is highlighted and appropriate follow-up action is recommended.

10.4.1.2 Apart from the statutory OZPs, a number of adopted / draft departmental Layout Plans as listed below are also reviewed:

· Adopted Sha Tin New Town Area 64 Layout Plan No. L/ST 64/1A

· Adopted Sha Tin New Town Area 72 Layout Plan – A Kung Kok Fishermen’s Village No. L/ST 72/1

· Draft Sha Tin Area 75 – Layout Plan No. L/ST 75/2D.

10.4.1.3 The Study Area of the Project is covered under two OZPs. They are the Approved Ma On Shan OZP No. S/MOS/22 (15.1.2016) and the Approved Sha Tin OZP No. S/ST/32 (11.12.2015). The landuse zones overlaid on the Project layout is shown in Figure No. 60334056/EIA/10.01. The land uses zones to be potentially affected by the Project and the future outlook of the area is discussed and summarised Table 10.3.

Table 10.3 Summary of the Review of Planning and Development Control Framework

OZP Plan Title and No.	Land Use Zonings	Approx. Area of the Land Use Zones to be affected	Current Design and Conservation Intention in the OZP	Potential change to the OZP and the anticipated future outlook of the area due to the Project.
Approved Sha Tin OZP No. S/ST/32 (11.12.2015) and Approved Ma On Shan OZP No. S/MOS/22 (15.1.2016)	Other Specified Uses (OU)	28ha	Sewage generated in the Sha Tin is treated in the existing STSTW.	Under the Project, the existing STSTW will be decommissioned and demolished. The STSTW will be relocated to Caverns. The demolished site will be cleared and pending for future developments. Since the future developments at the site of the existing STSTW after its decommissioning are under a separate project, any recommendation to the change in OZP shall be made later.
	GB	1.41ha	The current planning intention of this zone is primarily for defining the limits of urban and sub-urban development areas by natural woodland slopes at Nui Po Shan.	Under the Project, the existing natural woodland slopes in the GB Zone at Nui Po Shan will be removed for the construction and operation of the relocated STSTW facilities at the Main Portal Area, Secondary Portal Area, Ventilation Shaft and associated access road and site formation works. The Project shall be carefully designed to blend in the proposed above ground structures with the existing sloped woodland backdrop.

10.4.1.4 Since there would be change in the land use in the Approved Sha Tin OZP No. S/ST/32 (11.12.2015) and Approved Ma On Shan OZP No. S/MOS/22 (11.12.2016), ongoing liaison with PlanD regarding the revised boundary of the GB Zone shall be carried out throughout the design process. It is recommended that both the Sha Tin OZP and Ma On Shan OZP shall be amended to incorporate the latest changes arising from the Project when the design layouts are finalised.

10.4.1.5 Having reviewed the adopted / draft departmental Layout Plans as listed in Para 10.4.1.2, there would not be any conflict to the Layout Plans due to the Project.

10.6 Landscape Impact Assessment

10.6.1 Sources of Landscape Impacts

10.6.1.1 The sources of landscape impacts in the construction phase would include:

· Decommission and demolition of the existing STSTW;

· Construction of Main Tunnel Portals and ancillary facilities at Main Portal Area at A Kung Kok Street including Administration Building, Ventilation Building No. 1, Electrical Substation No. 1, etc. and associated site formation and natural terrain mitigation works including check dams;

· Construction of Secondary Tunnel Portal and ancillary facilities at Secondary Portal Area at Mui Tsz Lam Road including Ventilation Building No. 2, Electrical Substation No.2, etc. and associated site formation;

· Construction of Ventilation Shaft and a temporary project specific magazine at Nui Po Shan and associated access road connecting to existing A Kung Kok Shan Road;

· Decommission of the temporary project specific magazine after the completion of the construction of caverns;

· Construction of an underground twin 2m dia. pipe connecting the relocated STSTW and the existing emergency outfall;

· Temporary works at Area between A Kung Kok Street and Ma On Shan Road including construction of temporary site access and the temporary stockpiling area; and

· Temporary works at Area 73 including temporary site access, staff office area, temporary stocking piling area and workshops, etc.

10.6.1.2 The sources of landscape impacts in the operation phase would include:

· Ancillary facilities at Main Portal Area at A Kung Kok Street including Main Tunnel Portals, Administration Building, Ventilation Building No. 1, Electrical Substation No. 1 and associated site formation and natural terrain mitigation works including check dams;

· Ancillary facilities at Secondary Portal Area at Mui Tsz Lam Road including Secondary Tunnel Portal, Ventilation Building No. 2 and Electrical Substation No. 2 and associated site formation; and

· Ventilation Shaft at Nui Po Shan and associated access road connecting to existing A Kung Kok Shan Road.

10.6.1.3 As the construction of tunnels and caverns are conducted below ground, it is anticipated that there would not be any potential landscape impacts.

10.6.1.4 Since the sewage and sludge treatment facilities of the CSTW and the water reclamation facilities for the non-potable use of treated effluent from the CSTW would be installed inside the caverns, there would not be any potential landscape impacts due to installation of these facilities.

10.6.2 Magnitude of Landscape Impacts

10.6.3 Significance of Unmitigated Landscape Impacts

10.6.3.1 The significance of landscape impacts, before implementation of mitigation measures, in the construction and operation phases are assessed and presented in Table 10.12.

10.7 Visual Impact Assessment

10.7.1 Sources of Visual Impacts

10.7.1.1 The sources of visual impacts in the construction phase would include:

· Decommission and demolition of the existing STSTW;

· Construction of Secondary Tunnel Portal and ancillary facilities at Secondary Portal Area at Mui Tsz Lam Road including Ventilation Building and Electrical Substation, etc. and associated site formation;

· Construction of Ventilation Shaft and a temporary project specific magazine at Nui Po Shan and associated access road connecting to existing A Kung Kok Shan Road;

· Decommission of the temporary project specific magazine;

· Construction of an underground twin 2m dia. pipe connecting the relocated STSTW and the existing emergency outfall;

· Temporary Works at Area between A Kung Kok Street and Ma On Shan Road including construction of temporary site access and the temporary stockpiling area; and

· Temporary Works at Area 73 including temporary site access, staff office area, temporary stocking piling area and workshops, etc.

10.7.1.2 The sources of visual impacts in the operation phase would include:

· Ancillary facilities at Main Portal Area at A Kung Kok Street including Main Tunnel Portals, Administration Building, Ventilation Building No. 1, Electrical Substation No. 1, etc. and associated site formation and natural terrain mitigation works including check dams;

· Ancillary facilities at Secondary Portal Area at Mui Tsz Lam Road including Secondary Tunnel Portal, Ventilation Building No. 2 and Electrical Substation No. 2, etc. and associated site formation; and

· Ventilation Shaft at Nui Po Shan and associated access road connecting existing A Kung Kok Shan Road.

10.7.1.3 The locations and development details of permanent aboveground structures that would cause potential visual impact are summarised in Table 10.8.

Table 10.8 Locations and Development Details of Permanent Aboveground Structures

Location	Approximate Building Height (m) and Level (mPD) of the roof of the structure ^[Note]	Approximate Coverage (m)^[Note]
Main Portal Area
Administration Building	32m (+39mPD)	115m x 35m
Ventilation Building No. 1	51m (+59mPD)	55m x 20m
Electrical Substation No. 1	16m (+23.5mPD)	30m x 20m
Secondary Portal Area
Ventilation Building No. 2	36m (+51mPD)	50m x 25m
Electrical Substation No. 2	16m (+30.5mPD)	30m x 20m
Nui Po Shan Area
Ventilation Shaft	5m (+182mPD)	12m dia.

Note: Exact levels, heights and dimensions would be subject to detailed design.

10.7.1.4 As the construction of tunnels and caverns are conducted below ground, it is anticipated that there would not be any potential visual impacts.

10.7.1.5 Since the sewage and sludge treatment facilities of the CSTW and the water reclamation facilities for the non-potable use of treated effluent from the CSTW would be installed inside the caverns, there would not be any potential visual impacts due to installation of these facilities.

10.7.2 Magnitude of Visual Impacts

10.7.2.1 The magnitude of changes during construction and operation phases is assessed based on the viewing distance, compatibility of the project with the surrounding landscape, duration of changes, scale of development, reversibility of change, potential blockage of view as shown in Table 10.9.

10.7.2.2 During construction, the proposed temporary works at the existing STSTW, the areas at the both sides of Ma On Shan Road and the hillsides of A Kung Kok and along Mui Tsz Lam Road are generally at low level but cover a relatively large area. The compatibility of the Project during construction phase is considered as medium. The construction works will last for a few years and the duration of impact would be medium. The scale of development is considered large as the Project covers large temporary works areas. All permanent works including site formation constructed during construction phase are considered irreversible. Generally, there would not be any potential blockage of view during construction.

10.7.2.3 During the operation, the compatibility of the Project is considered high as there will not be any aboveground structures at STSTW and the proposed facilities at Main Portal Area, Secondary Portal Area, Ventilation Shaft and access road are relatively localised and would fit in well with the surrounding landscape and visual context. The compatibility of the Project during operation is considered as high. The duration of impact due to permanent aboveground works is long. The scale of development is medium as all the proposed permanent works are small scale and localised. All permanent works during operation phase are considered as irreversible. Generally, there would not be any potential blockage of view during operation.

10.7.2.4 It is predicted that there would be large to medium magnitude of impact on VSRs at low level who are immediately close to the Project and adjacent elevated VSRs who have an overview of the Project; and slight to insubstantial magnitude of impact on distant VSRs during construction and operation.

10.7.3 Significance of Unmitigated Visual Impacts

10.7.3.1 The significance of visual impacts, before the implementation of mitigation measures, in the construction phase and operation phase are assessed in accordance with the methodology set out in Table 10.2 of the Report and described in Table 10.13.

10.7.4 Recommended Photomontage Viewpoints

10.7.4.1 Computer generated photomontages will be prepared to illustrate the potential landscape and visual impact of the Project. The criteria for the selection of representative viewpoints for photomontages include: -

· the viewpoints which cover the aboveground structure viewed from major public viewpoint represents key VSRs or VSR groups who would be potentially affected by the proposed Project; and

· the viewpoints which shall be able to represent the worst case scenarios and demonstrate the compatibility of the aboveground structures to the adjacent visual context and illustrate the visual effect during Day 1 without mitigation measures, Day 1 with mitigation measures and Year 10 with mitigation measures.

10.7.4.2 Based on the location of the proposed aboveground structures, proposed viewpoint from key representative VSRs are mapped in Figure No. 60334056/EIA/10.31 and the computer generated photomontages to illustrate the potential landscape and visual impact of the Project is shown in Figure Nos. 60334056/EIA/10.51 to 10.56. They are described as follow:

10.8 Landscape and Visual Mitigation Measures

10.8.1.1 The proposed engineering works have been designed to minimise any potential landscape and visual impact as much as possible. Unavoidably, there would be some potential landscape and visual impact. Landscape and Visual Mitigation Measures are therefore proposed to alleviate the potential adverse landscape and visual impact.

10.8.1.2 The proposed landscape and visual mitigation measures in the construction and operation are listed in Tables 10.10 and 10.11 below, together with an indication of Funding, Implementation and Maintenance Agencies and illustrated in Figure Nos. 60334056/EIA/10.41 to 10.46.

* Remarks: The future development agent has yet to be identified as there is no confirmed planning and schedule for the development of the vacated site. Nevertheless, the arrangement of maintenance/management agencies shall follow the prevailing government practices as given in DEVB TCW No. 6/2015 or its version.

10.8.1.3 The construction phase mitigation measures listed above shall be implemented as early as possible in order to minimise the landscape impacts in the construction stage. The operation phase mitigation measures listed above shall be adopted during the detailed design and be built as part of the construction works at the last stage of the construction period so that they are in place at the date of commissioning of the Project. However, it should be noted that the full effect of the soft landscape mitigation measures would not be appreciated for several years. Photomontages of the proposed project without and with mitigation measures illustrating the appearance after 10 years of the proposed works are shown in Figure Nos. 60334056/EIA/10.51 to 10.56.

10.9 Residual Impact

10.9.1 Significance of Residual Landscape Impacts

10.9.1.1 The potential significance of the landscape impacts during the construction and operation phases, before and after mitigation, is provided in Table 10.12. The assessment follows the proposed methodology and assumes that the appropriate mitigation measures identified in Tables 10.10 and 10.11 above would be implemented, and the full effect of the soft landscape mitigation measures would be realised after ten years.

10.9.1.2 Under the proposed decommissioning and demolition works for the existing STSTW, the existing buildings and underground structures will be removed. Majority of the existing at-grade vegetation will be preserved in-situ. Green roofs, vertical greening attached to existing buildings and vegetation above existing underground structures and utilities will be removed during demolition. The magnitude of impact is considered small. The sensitivity of the Amenity Planting in the Existing STSTW (LR-01) is medium and the resultant unmitigated landscape impact on this LR would be slight during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting and hydroseeding on the disturbed ground surface after demolition works, there would not be any discernible net gain or loss to LR-01 with proposed mitigation measures. It is predicted that there would be slight residual impact on LR-01 during construction, insubstantial residual impact during day 1 and year 10 of operation.

10.9.1.3 Under the construction of temporary works at area between A Kung Kok Street and Ma On Shan Road including construction of temporary site access and the temporary stockpiling area, it is estimated that approximately 190 nos. of existing trees and 17,700m² of vegetation in the Roadside Planting Areas along Ma On Shan Road (LR-07) would be affected during the construction. Affected trees species include Aleurites moluccana, Bauhinia purpurea, Bombax ceiba, Casuarina equisetifolia, Delonix regia, Ficus microcarpa, Leucaena leucocephala and Melaleuca cajuputi subsp. Cumingiana. They are generally of medium form and fair amenity value. The affected trees are in the range of 4-10m high, 3-9m spread and 100-600mm trunk diameter. The sensitivity of this LR is medium and the magnitude of impact is intermediate. The resultant unmitigated landscape impact on this LR would be moderate during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting, reinstatement of temporarily disturbed landscape areas, there would not be any discernible net gain or loss in area to LR-07 with proposed mitigation measures. Based on a broad brush estimate, approximate 190 nos. heavy standard trees can be compensated within the reinstated landscape area of this LR. It is predicted that there would be moderate residual impact during construction, slight residual impact during day 1 of operation and insubstantial residual impact on LR-07 when the proposed compensatory planting and roadside amenity planting become mature during year 10 of the operation.

10.9.1.4 Based on a broad brush estimate, approximately 638 nos. of existing trees and 59,900m² existing vegetation will be removed on Slopes of Nui Po Shan (LR-08) for the construction at Main Portal Area, Secondary Portal Area, Ventilation Shaft at Nui Po Shan and associated access road, and site formation for Temporary Project Magazine. Affected tree species include Acacia confusa, Aporusa dioica, Cleistocalyx operculata, Litchi chinensis, Cratoxylum cochinchinense, Ficus microcarpa, Macaranga tanarius, and Schefflera heptaphylla. They are generally of medium form and fair to poor amenity value. Affected trees are in the range of 3-14m high, 3-10m spread and 95-800mm trunk diameter. The sensitivity of this LR is high and the magnitude of impact is large. The resultant unmitigated landscape impact on this LR would be substantial during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees and compensatory tree planting, reinstatement of temporarily disturbed landscape areas, tree and shrub planting at the Temporary Project Magazine Site after construction, provision of green roof, buffer planting and woodland mix planting on new soil slopes. Based on a broad brush estimate, approximately 140 nos. heavy standard trees can be compensated in Temporary Project Magazine Site (within approximate 3,900m²compensatory woodland mix planting) after Completion of Engineering Works and approximately 10,000 nos. of tree whips can be compensated on the woodland mix planting areas on new slopes and the reinstatement planting areas (approximately 30,800m²planting areas) of this LR. As such, there would be a net permanent loss of 25,200m² of LR-08 due to the Project. It is predicted that there would be substantial residual impact during construction, moderate residual impact during day 1 of operation after implementation of landscape works and slight residual impact on LR-08 when the proposed compensatory planting, buffer planting and woodland mix planting become mature during year 10 of the operation.

10.9.1.5 During construction, approximately 300m of the cycle track connecting the waterfront promenade at Shing Mun River Channel and A Kung Kok Street will be temporarily alienated in order to form a temporary access road connecting to the works area at Area 73. The sensitivity of this LR is medium and the magnitude of impact is large. The resultant unmitigated landscape impact on the cycle track would be moderate during construction and operation. With the implementation of proposed mitigation measures, there would not be any net gain or loss to this landscape resource with proposed mitigation measures. It is predicted that there would still be moderate residual impact during construction and the residual impact would be reduced to insubstantial after the affected cycle track is reprovided.

10.9.1.6 Apart from LR-01, LR-07, LR-08 and LR-17, it is predicted that there would not be any discernable change in other LRs identified within the study boundary of the Project.

10.9.1.7 Under the Project, it is anticipated that there would be permanent change in Sha Tin Waterfront Industrial LCA (LCA-01) due to the decommission and demolition of the existing STSTW including clearance of aboveground and underground facilities and associated green roof and vertical greening and associated vegetation during construction. Majority of existing vegetation at-grade will be retained. The sensitivity of this LCA is low. The magnitude of impact is small. The resultant unmitigated landscape impact on this LCA would be slight during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting, control of night-time lighting glare, erection of decorative screen hoarding, management of construction activities and facilities and hydroseeding on the disturbed ground surface after demolition works, it is predicted that there would be slight residual impact during construction, insubstantial residual impact during day 1 and year 10 of the operation.

10.9.1.8 It is predicted that there would be a temporary change in Ma On Shan Transportation Corridor LCA (LCA-04) due to the construction of temporary site assess, temporary staff office, stockpiling and associated works during construction phase. It is estimated that approximate 17,700 m² of existing vegetation along roadsides in the LCA will be removed during construction. The magnitude of impact is intermediate. The sensitivity of this LCA is low. The resultant unmitigated landscape impact on this LCA would be moderate during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting, control of night-time lighting glare, erection of decorative screen hoarding, management of construction activities and facilities, reinstatement of temporarily disturbed landscape areas, reprovisioning of the affected cycle track and provision of roadside amenity planting, it is predicted that there would be moderate residual impact during construction, slight residual impact during day 1 of operation and insubstantial residual impact on LCA-04 when the proposed compensatory planting and roadside amenity planting become mature during year 10 of the operation.

10.9.1.9 It is predicted that there would be a temporary change in A Kung Kok and Tai Shui Hang Miscellaneous Urban Fringe LCA (LCA-05) due to the construction activities at Main Portal Area and Secondary Portal and associated temporary works and permanent change in landscape character due to the operation of the Project. It is estimated that approximate 37,400m² woodland on the hillside slope at Nui Po Shan will be lost during construction. The magnitude of impact is large. The sensitivity of this LCA is high. The resultant unmitigated landscape impact on this LCA would be substantial during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting, control of night-time lighting glare, erection of decorative screen hoarding, management of construction activities and facilities, reinstatement of temporarily disturbed landscape areas, aesthetically pleasing design of aboveground structures, provision of green roof on aboveground structures, provision of buffer planting and woodland mix planting on new soil slopes, it is predicted that there would be substantial residual impact during construction, moderate residual impact during day 1 of operation after implementation of landscape works and slight residual impact on LCA-05 when the proposed compensatory planting, buffer planting and woodland mix planting become mature during year 10 of the operation.

10.9.1.10 It is predicted that there would be a temporary change in A Kung Kok Settled Valley LCA (LCA-07) due to the construction of Ventilation Shaft, temporary Magazine Site and associated access road and permanent change in the landscape character due to the operation of the Project. It is estimated that approximate 22,500m² woodland on the valley of Nui Po Shan will be lost during construction. The magnitude of impact is large. The sensitivity of this LCA is high. The resultant unmitigated landscape impact on this LCA would be substantial during construction and operation. With the implementation of proposed mitigation measures, including preservation of existing vegetation, transplanting of affected trees, compensatory tree planting, control of night-time lighting glare, erection of decorative screen hoarding, management of construction activities and facilities, reinstatement of temporarily disturbed landscape areas, tree and shrub planting of the Temporary Magazine Site after construction, aesthetically pleasing design of the Ventilation Shaft and retaining structures for the access road, provision woodland mix planting on new soil slopes, it is predicted that there would be substantial residual impact during construction, moderate residual impact during day 1 of operation after implementation of landscape works and slight residual impact on LCA-07 when the proposed compensatory planting, tree and shrub planting on the Temporary Magazine Site and woodland mix planting on new soil slopes become mature during year 10 of the operation.

10.9.1.11 Apart from LCA-01, LCA-04, LCA-05 and LCA-07, it is predicted that there would not be any discernable change in other LCAs identified within the study boundary of the Project.
