9.2.2 The Outline Zoning Plan (OZP) gazetted under the Town Planning Ordinance provides the statutory framework for land use development. Reference has been made to the Approved Sha Tin OZP No. S/ST/34 (8.6.2018).
9.3.1 The landscape impacts have been assessed according to the following procedures.
· 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 9.1 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.

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.
9.3.2 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 Estimated number of VSR population. This is expressed in terms of whether there are “many“, “medium” and “few” VSRs in any one category of VSR.
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 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 potential blockage of view 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 visual 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.

The Revised T4 provides a
direct trunk road linking Sha Tin Road with Shing Mun Tunnel Road and Tsing Sha
Highway. It is designed to provide a direct connection for through traffic
between Ma On Shan area and Tsuen Wan / West Kowloon
areas bypassing the busy at-grade road network of Sha Tin Central. The proposed
road works mainly aligned adjoining or above the existing road networks.
Starting from the northern portion of the Project, approximately 2,760m2 of
R(B) and 680m2
of O will be affected by the slope works along
the northern side of Shing Mun Tunnel Road near Mei Tin Road. Some portion 490m2 of
R(A) near Mei Lam Estate will be involved for the modification works on the
existing Tsing Sha Highway. Approximately 1,290m2 of
R(B) near Chung Ling Lane and 1,960m2 of I in Tai
Wai Industrial Area will be affected by the proposed elevated roads. The
proposed elevated roads will also overlap with approximately 2,030m2 with the OU along the East Rail Line Railway at the junction of Shing Mun
Tunnel Road and Tai Po Road. There is major change on the G/IC at the existing
carparking and amenity areas outside Hong Kong Heritage Museum, involving the
construction of elevated roads of approximately 5,750m2.
For the south of Shing Mun River Channel, small portion 310m2 of
O along the promenade and 1,150m2
of CDA(1) adjoining The
Riverpark will be affected by the proposed roads, excluding the re-arrangement
of pedestrian subway and cycle path system. Approximately 1,430m2 of
V near Sha Tin Tau Village,
290m2 of V
near Tsang Tai Uk and 160m2 of
O near Tsang Tai Uk Recreation Ground will be
affected by the construction of depressed roads and slip road along Lion Rock
Tunnel Road. For the widening works along Sha Tin Road, approximate 830m2 of
R(A) near SIMAR slopes of Pok Hong Estate and small
portion 280m2
of V near SIMAR slopes of Tsok
Pok Hang San Tsuen will be affected. The impact on
the OZP is illustrated in Figure 9.1.

9.5.16 Among the Residential VSRs, the sensitivities of R-03, R-05 and R-06 are considered as high in view of the many number of population, good quality of existing view and full degree of visibility to the Project. The remaining residential VSRs are considered as medium sensitivity since R-01, R-02 and R-04 are either with glimpse visibility to the site, partial visibility with poor quality of existing view or fair quality of existing view with alternative view available.
9.5.17 Among the Institutional VSRs, the sensitivities of I-02, I-03, I-04 and I-07 are considered as medium since they have occasional view with partial to full visibility to the Project. For I-01, I-05, I-06 and I-08 with low sensitivity, they have glimpse degree of visibility to the Project or with rare frequency of view.
9.5.18 For the Recreational VSRs, the sensitivity of O-01, O-04 and O-05 with fair to good quality of existing view and occasional to frequent view to the Project is graded as high. The O-03 is considered as medium sensitivity since the recreational activity is mainly indoor with rare frequency of view to the Project. For O-02 with few number of individual and poor quality of existing view under the flyover of Shing Mun Tunnel Road, the sensitivity is considered as low.
9.5.19 For the Travelling VSRs, sensitivity of VSRs with full degree of visibility to the Project (i.e. T-01, T-03 and T-06) is graded as medium, while those VSRs with partial degree of visibility (i.e. T-02, T-04 and T-05) is graded as low.
9.5.20 The sensitivity of Industrial VSR W-01 is considered as low since the VSR usually engaged in work with occasional view to the Project and also the existing quality of view is poor.

9.6.1 The Project will involve various sources of landscape impact. The proposed development will create varying levels of impact on the landscape resources and landscape character areas at different stages of its lifetime. Potential landscape impact from above ground development and the footprint of construction works and operational facilities is concentrated upon for the purpose of the assessment.
9.6.2 The sources of landscape impacts in the construction phase would include:
·
Site
clearance and tree removal/transplanting;
· Site formation works and slope works including creation of hoarding, cutting and filling;
· Construction of new lanes, widen existing roads, depressed roads, underpass, flyovers, noise barriers / enclosures, bridges and associated slope works;
· Re-arrangement of footbridge, pedestrian subway and cycle path system affected by the road works;
· Temporary site areas, site offices, haul road, storage of construction materials, equipment and plants, hoarding, construction traffic etc.; and
· Construction of natural terrain hazards mitigation works (i.e. flexible barrier) and associated works with maintenance path.
9.6.3 The sources of landscape impacts in the operation phase would include:
·
Operation
of re-arranged footbridge, pedestrian subway and cycle
path system affected by the road widening works.
9.6.4 The magnitude of landscape changes before implementation of mitigation measures associated with the construction phase and operational phases of the Project are assessed and described in Table 9.7 for Landscape Recourse (LR) and Table 9.8 for Landscape Character Area (LCA) respectively.

9.6.5 The significance of landscape impacts, before implementation of mitigation measures, in the construction and operation phases are assessed and presented in Table 9.12.
9.7.1 The sources of visual impacts in the construction phase would include:
·
Site
clearance and tree removal/transplanting;
· Site formation works and slope works including creation of hoarding, cutting and filling;
· Construction of new lanes, widen existing roads, depressed roads, underpass, flyovers, noise barriers / enclosures, bridges and associated slope works;
· Re-arrangement of footbridge, pedestrian subway and cycle path system affected by the road works;
· Temporary site areas, site offices, haul road, storage of construction materials, equipment and plants, hoarding, construction traffic etc.;
· Potential night-time glare arising from the lighting of construction activities;
· Dust and construction debris; and
· Construction of natural terrain hazards mitigation works (i.e. flexible barrier) and associated works with maintenance path.
9.7.2 The sources of visual impacts in the operation phase would include:
·
Operation
of new lanes, widen existing roads, depressed roads, underpass, flyovers, noise
barriers / enclosures, bridges and associated slope works;
·
Operation
of re-arranged footbridge, pedestrian subway and cycle path system affected by the
road widening works; and
· Increased road traffic and road lighting.
9.7.3 The magnitude of visual changes before implementation of mitigation measures 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 9.9.
9.7.4 In general, the duration of impacts will be medium as the construction works will last for a few years, and the duration of impacts will be long during operation phase since the road works are permanent and irreversible. In view of the nature of road works, the scale of developments for the travelling VSRs during construction phase will be large. The scale of development for most of the areas will be medium. Those road improvement works along Tsing Sha Highway and near Mei Tin Road will be small in scale, while the scale of development for construction of noise enclosure along Sha Tin Road will be considered as large.
9.7.5 The existing views of VSRs near the proposed noise enclosure along Sha Tin Road (including R-05, I-06 and I-07) will be partially blocked during both construction and operation phase. The magnitude of change is considered to be large. The magnitude of change for R-06 will be large during construction of the depressed road and underpass and intermediate upon completion of the road works.
9.7.6 For those travelling VSRs (T-01, T-02, T-03, T-04, T-05 and T-06), the magnitude of change during construction will be large, but the magnitude of change will be small upon completion of the road works as the proposed works are highly compatible to the surrounding visual context.
9.7.7 Most of the VSRs involve partial blockage to existing views and medium scale of development. They are R-03, R-04, I-01, I-03, I-04, I-05, O-01, O-03, O-04 and W-01. The magnitude of change for these VSRs is considered as intermediate.
9.7.8 There will be no blockage to the existing views and the scale of development is medium for VSRs R-01, O-02 and O-05. Although the scale of development along Sha Tin Road is large, but there will be no blockage to existing views for the distant VSR I-08. Hence, the proposed works are compatible to the surrounding visual context and the magnitude of change for these VSRs is considered to be small.
9.7.9 For other VSRs, including R-02 and I-02, there will be no blockage to the existing views and the scale of development is small. The proposed works are highly compatible to the surrounding visual context. The magnitude of change for these VSRs is considered to be negligible.

9.7.10 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 9.2 of the Report and described in Table 9.13.
9.7.11 The visual impacts before mitigation on immediately adjacent VSRs (i.e. R-05 and I-07) with medium to high sensitivity and full overview of the proposed noise enclosure and associated slope works along Sha Tin Road are substantial both during construction and operation phases. The visual impact before mitigation on R-06 with high sensitivity and overview of the proposed structures along Lion Rock Tunnel Road south of the Shing Mun River Channel is substantial during construction and moderate upon completion of the proposed elevated road, underpass and depressed road near Sha Tin Tau.
9.7.12 The unmitigated visual impacts on VSRs R-03, R-04, I-03, I-04, O-01, O-03, O-04 and O-05, with medium to high sensitivity and intermediate magnitude of change, are moderate both during construction and operation phases. I-06 is close to the proposed noise enclosure along Sha Tin Road, the unmitigated visual impact is moderate both during construction and operation phases in view of its low sensitivity.
9.7.13 All travelling VSRs are with moderate unmitigated visual impacts during construction due to the proposed roadworks. T-01, T-03 and T-06 still have slight unmitigated visual impacts during operation phase as they are the travellers along the proposed roadworks. The unmitigated visual impacts upon completion of the proposed roadworks for the other travelling VSRs T-02, T-04 and T-05 are insubstantial.
9.7.14 Visual impact before mitigation on R-01 with medium sensitivity and small magnitude of change is slight both during construction and operation phases. VSRs I-01, I-05 and W-01 also have slight unmitigated visual impacts with low sensitivity and intermediate magnitude of change.
9.7.15 R-02 and I-02 with negligible magnitude of change, hence, the visual impacts before mitigation is insubstantial for both construction and operation phases. The unmitigated visual impacts during construction and operation phases for O-02 and I-08 with low sensitivity and small magnitude of change are also assessed as insubstantial.

9.7.18 The recommended viewpoints cover all VSRs with visual impacts before mitigation for the Project. Since I-08 and O-02 have insubstantial unmitigated visual impacts, no viewpoints are recommended for these VSRs.
9.8.1 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.

9.8.3 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 be appreciated after year 10 of the operation.
9.9.1 The potential significance of the landscape impacts during the construction and operation phases, before and after mitigation, is provided in Table 9.12. The assessment follows the proposed methodology and assumes that the appropriate mitigation measures identified in Tables 9.10 and 9.11 above would be implemented, and the full effect of the soft landscape mitigation measures would be realised after ten years.
9.9.2 For the LRs under the Project, it is anticipated that there would be temporary and permanent change in Woodland and Mixed Woodland near Needle Hill (LR-1.1) due to the construction of new elevated roads and associated slope works. It is estimated that approximate 100m2 of area of this LR will be affected, and approximate 6 nos. of existing trees are being affected by the construction of elevated roads (near Mei Tin Road). The sensitivity of this LR is high. The magnitude of change is small. The resultant unmitigated landscape impact on this LR would be moderate during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5), reinstatement of temporarily disturbed landscape areas (CM7), landscape treatment on slopes (OM2) and aesthetically pleasing design for footbridges, pedestrian subways, cycle paths, carriageways and other highways structures (OM7), it is predicted that there would still be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.3 It is predicted that there would be a temporary and permanent change in Woodland and Mixed Woodland near Sha Tin Road (LR-1.2) due to the construction of new lanes, road widening, noise barriers / enclosures and associated slope works. It is estimated that approximate 765m2 of area of this LR will be affected. Approximate 50 nos. of existing trees are being affected by the road widening and construction of noise barriers / enclosures and flexible barrier in which approximate 20 nos. of existing trees are within Lion Rock Country Park. No species with conservation importance will be affected. The sensitivity of this LR is high. The magnitude of impact is small. The resultant unmitigated landscape change on this LR would be moderate during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5), reinstatement of temporarily disturbed landscape areas (CM7), compensatory planting for loss of existing trees (OM1), landscape treatment on slopes (OM2), visually pleasing aesthetic treatment on noise barriers and noise enclosures (OM6) and aesthetically pleasing design for footbridges, pedestrian subways, cycle paths, carriageways and other highways structures (OM7), it is predicted that there would still be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.4 It is anticipated that there would be a temporary and permanent change in Tree and Shrub Planting in Village Areas near Lai Chi Yuen (LR-1.3) due to the construction of new elevated roads, extension of existing stub elevated road and noise barriers. It is estimated that approximate 750m2 of area of this LR will be involved, but only those areas for viaduct piers of the elevated roads will be affected. Most of the works near this LR is about the modification works on the existing elevated roads above Chung Ling Road, which will not affect the existing trees underneath and the 5 nos. of OVTs in the vicinity. Approximate 26 nos. of existing trees along Chung Ling Lane are being affected by the construction of viaduct piers for the extension of existing stub elevated road above. The sensitivity of this LR is high. The magnitude of change is small. The resultant unmitigated landscape impact on this LR would be moderate during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), preservation of old and valuable trees (OVTs) (CM2), control of night-time lighting glare (CM4), erection of decorative screen hoarding, reinstatement of temporarily disturbed landscape areas (CM7), provision of screen planting (OM3), maximization of roadside planting (OM4), visually pleasing aesthetic treatment on noise barriers and noise enclosures (OM6) and aesthetically pleasing design for footbridges, pedestrian subways, cycle paths, carriageways and other highways structures (OM7), it is predicted that there would still be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.5 It is predicted that there would be a temporary and permanent change in Tree and Shrub Planting in Village Areas Near Tsang Tai Uk (LR-1.4) due to the Construction of new elevated road, underpass, depressed road and associated slope works. It is estimated that approximate 3,900m2 of area of this LR will be affected by the construction of underpass, depressed road and elevated road, and approximate 25 nos. of existing trees are being affected mainly by the construction of underpass and depressed road and associated slope works. The sensitivity of this LR is medium. The magnitude of change is large. The resultant unmitigated landscape impact on this LR would be substantial during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5), reinstatement of temporarily disturbed landscape areas (CM7), compensatory planting for loss of existing trees (OM1), landscape treatment on slopes (OM2), provision of screen planting (OM3), maximization of roadside planting (CM4), visually pleasing aesthetic treatment on noise barriers and noise enclosures (OM6) and aesthetically pleasing design for footbridges, pedestrian subways, cycle paths, carriageways and other highways structures (OM7), it is predicted that there would be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.6 It is anticipated that there would be a temporary and permanent change in the waterbodies in Shing Mun River Channel (LR-2.2) due to the construction of new bridges, elevated road and noise barriers / semi-enclosures across the river channel. It is estimated that approximate 200m2 of area of this LR fall within the alignment of proposed bridge, but only a small section for drilling and piling works of foundation of the bridges will be affected (near Hong Kong Heritage Museum and near Shing Mun Tunnel Road). The sensitivity of this LR is medium. The magnitude of change is small. The resultant unmitigated landscape impact on this LR would be slight during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5) and reinstatement of affected watercourses (CM8), it is predicted that there would be slight residual impact during construction, and would reduce to insubstantial residual impact during day 1 and after year 10 of the operation.
9.9.7 It is predicted that there would be a permanent change in the modified Watercourse in Sha Tin Tau (LR-2.3) due to the construction of new underpass, depressed road, noise barriers and associated slope works, as well as the re-arrangement of footbridge and pedestrian subway system affected by the road works. It is estimated that approximate 220m long at the southern portion of modified watercourse are being affected mainly by the construction of underpass and associated slope works. The sensitivity of this LR is low. Since the affected section is small in size, highly modified and experienced frequent disturbance frequent disturbance from nearby residential areas and road traffic, the magnitude of change is considered as small. The resultant unmitigated landscape impact on this LR would be slight during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5) and reinstatement of affected watercourses (CM8), it is predicted that there would be slight residual impact during construction, and would reduce to insubstantial residual impact during day 1 and after year 10 of the operation.
9.9.8 It is anticipated that there would be a temporary and permanent change in Sha Tin Tau Village Sitting-Out Area (LR-3.5) due to the construction of new underpass, depressed road, noise barriers and associated slope works. It is estimated that The whole area of this LR (approximate 930m2) will be affected by the construction of underpass, depressed road and associated slope works. Most of the landscape impact on this LR is temporary and the affected open space will be closed during construction and re-instated upon the completion of the underpass and depressed road. Approximate 28 nos. of existing trees are being affected by the construction of underpass, depressed road and associated slope works. The sensitivity of this LR is medium. The magnitude of change is large during construction and would reduce to intermediate during operation. The resultant unmitigated landscape impact on this LR would be substantial during construction and moderate during operation. With the implementation of proposed mitigation measures, such as control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5), reinstatement of temporarily disturbed landscape areas (CM7), compensatory planting for loss of existing trees (OM1), provision of screen planting (OM3), maximization of roadside planting (OM4) and re-provision of affected open space (OM5), it is predicted that there would still be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.9 It is predicted that there would be a temporary permanent change in Shing Mun River Promenade (LR-3.6) due to the construction of new bridges and noise barriers / semi-enclosures across the river channel. It is estimated that approximate 700m2 of area of this LR will be affected by the construction of new bridges (near Hong Kong Heritage Museum and near The Riverpark). Approximate 29 nos. of existing trees are being affected by the construction of new bridges. Trees of particular interest within this LR would be preserved and not be affected. In compared with the whole Shing Mun River Promenade, the affected area and affected trees of this LR is considered as small. The sensitivity of this LR is high. The magnitude of change is small. The resultant unmitigated landscape impact on this LR would be moderate during construction and operation. With the implementation of proposed mitigation measures, such as preservation of existing vegetation (CM1), control of night-time lighting glare (CM4), erection of decorative screen hoarding (CM5), reinstatement of temporarily disturbed landscape areas (CM7), compensatory planting for loss of existing trees (OM1), provision of screen planting (OM3), maximization of roadside planting (OM4), visually pleasing aesthetic treatment on noise barriers and noise enclosures (OM6) and aesthetically pleasing design for footbridges, pedestrian subways, cycle paths, carriageways and other highways structures (OM7), it is predicted that there would still be moderate residual impact during construction, and would reduce to slight residual impact during day 1 and further reduce to insubstantial after year 10 of the operation.
9.9.10 It is anticipated that there would be a temporary and permanent change in Landscape Areas in Urban Development Area near Lion Rock Tunnel Road (LR-4.2) due to the construction of new elevated roads and noise barriers / semi-enclosures, temporary site office and storage of construction materials, equipment and plants, and re-arrangement of footbridge, pedestrian subway and cycle path system affected by the road works. It is estimated that approximate 8,500m2 of area of this LR will be affected by the construction of new elevated roads and noise barriers / semi-enclosures. The existing carpark and the surrounding areas outside Hong Kong Heritage Museum will be used as temporary site office and storage of construction materials tentatively. The footbridge, pedestrian subway and cycle path near The Riverpark will be re-arranged and re-provided upon the construction of road works. Approximate 214 nos. of existing trees are being affected by the project, in which one tree of particular interest Ficus benjamina with DBH over 1m outside Hong Kong Heritage Museum will be unavoidably directly affected by the construction of elevated roads. Tree transplanting is proposed, subject to the review on technical feasibility and sensitivity analysis in detail design stage. Various limitations to be carefully considered in detail design stage such as the arrangement of long root pruning period along the roadside, formation of large root ball, temporary traffic/construction arrangement for uplifting and transplanting the large tree, availability of final receptor location for the large tree in the vicinity, tree safety concern during root pruning period and after transplanting, the ability to recover from transplanting stress and the cost effectiveness etc. The final decision on tree transplanting will be confirmed in detail design stage taking into account the mentioned limitations and further advice from the existing and future tree maintenance departments. In case removal of the subject tree of particular interest is considered unavoidable in later stage, the procedures as set out in Section 2.6 of the TRAM Guidelines and suitable initiatives to commemorate the tree (e.g. replanting) shall be considered in accordance with Para. 26 (d) of DEVB TC(W) No. 4/2020.

It is estimated that approximate 4,000m2 of area of this LR will be affected by the project. For the involved area located at the road verge planting areas covered by the elevated roads near Tung Lo Wan Village, only those along Chung Ling Lane will be affected by the construction of viaduct piers for the extension of existing stub elevated road above. For the roadside planting areas at the periphery of Tai Wai industrial area, only those areas for construction of viaduct piers of the elevated roads will be affected. For central reserve area of Sha Tin Road near Pok Hong Estate will be affected by the construction of noise enclosure and road widening works. Approximate 116 nos. of existing trees are being affected by the project, in which 3 nos. of Pterocarpus indicus with conservation importance along Chung Ling Road are unavoidably affected and proposed to be felled. Although it is listed as “Endangered” under IUCN Red List of Threatened Species, it is a common ornamental species easily found in open space in Hong Kong. The sensitivity of this LR is high.

Summary on Recommendation in Broad
Brush Tree and Vegetation Survey
9.9.26 Based on the broad-brush tree estimate with approximately 3,685 nos. of trees surveyed, approximate 1,051 nos. of existing trees including 13 nos. of trees of particular interest will be unavoidably affected by the Project. All the 6 nos. of registered OVTs in the vicinity of the project boundary will be retained in-situ and not be affected by the Project. One tree of particular interest Ficus benjamina with high amenity value and large size outside the Hong Kong Heritage Museum will be unavoidably affected and tree transplanting is proposed, subject to the review on technical feasibility and sensitivity analysis in detail design stage and further advice from the existing and future tree maintenance departments. In case removal of the subject tree of particular interest is considered unavoidable in later stage, the procedures as set out in Section 2.6 of the TRAM Guidelines and suitable initiatives to commemorate the tree (e.g. replanting) shall be considered in accordance with Para. 26 (d) of DEVB TC(W) No. 4/2020. For the remaining approximate 1,050 nos. of affected trees, tree felling will be proposed. The major affected tree species in the individual tree survey include Ailanthus fordii, Canthium dicoccum, Ficus benjamina and Pterocarpus indicus. The major affected tree species in tree group survey include Acacia confusa, Bridelia tomentosa, Casuarina equisetifolia, Eucalyptus tereticornis, Ficus microcarpa, Melia azedarach, Polyspora axillaris, Sterculia lanceolata and Schima superba.
9.9.27 Among the affected trees proposed to be felled, an approximate of 12 nos. of trees of particular interest in species with conservation importance will be inevitably affected and proposed to be felled. They include 2 nos. of Ailanthus fordii, 7 nos. of Canthium dicoccum and 3 nos. of Pterocarpus indicus. The Ailanthus fordii and 5 nos. of Canthium dicoccum are located on the SIMAR slopes between Tsang Tai Uk and Sha Tin Tau Village (LR-5.3) and in conflict with the construction of depressed road, underpass and associated slope works, while the 2 nos. of Canthium dicoccum are located on the SIMAR slopes along Sha Tin Road (LR-5.3) affected by the proposed road widening, noise enclosure and associated slope works. The 3 nos. of affected Pterocarpus indicus are located in Tree and Shrub Planting in Roadside Areas along Chung Ling Road (LR-5.4). Since most of the affected trees are located either on natural terrain or engineered slopes, their survival rate after transplanting is low and not feasible for transplanting. Therefore, tree felling is proposed with compensatory planting.
9.9.28 Due to the limited site areas within developed built-up areas in Sha Tin, tree compensatory planting in roadside and flat areas and woodland mix planting on slopes are proposed subject to the gradient of the proposed new slopes. A minimum of 250 heavy standard trees will be proposed at roadside flat areas, at the re-provided Sha Tin Tau Village Sitting-out Area and at the planting areas of elevated roads with shade-tolerant tree species. The proposed species are commonly used in urban environment so as to reinstate and enhance the surrounding landscape value. Reference could be made to Greening Master Plan issued by CEDD and Street Tree Selection Guide promulgated by DEVB.
9.9.29 Total area of approximate 11,300m2 will be proposed as compensatory woodland mix planting with approximately 3,400 nos. of tree whips to be planted. Mix of native tree species will be proposed in reference to Guiding Principles on Use of Native Plant Species in Public Works Projects promulgated by DEVB to improve the vegetation diversity, enhance ecological value and re-creation of vegetation habitat particular for areas adjoining the Lion Rock Country Park. The proposed location for compensatory tree planting and compensatory woodland mix is shown in Figure 9.9.1, Figure 9.9.2, Figure 9.9.3, Figure 9.9.4, and Figure 9.9.5.

9.9.30 The potential significance of the visual impacts during the construction and operation phases, before and after mitigation, is provided in Table 9.13. The assessment followed the proposed methodology and assumed that the appropriate mitigation measures identified in Table 9.10 and Table 9.11 above would be implemented, and the full effect of the visual mitigation measures should be realised after ten years.
9.9.31 Photomontages illustrating the potential visual impact during operation with and without mitigation measures from representative VPs due to the Project are shown in Figure 9.10.1, Figure 9.10.2, Figure 9.10.3, Figure 9.10.4, Figure 9.10.5, Figure 9.10.6, Figure 9.10.7, Figure 9.10.8, Figure 9.10.9, Figure 9.10.10, and Figure 9.10.11. The potential visual impacts are assessed and summarised as below:
· Viewpoint VP01 near the cycle track adjoining Scenery Court which is an at-grade view approximately 100m from the proposed works. It demonstrates the potential landscape and visual impact due to the proposed elevated roads with noise barriers outside Hong Kong Heritage Museum; The layout and appearance of the noise barriers have been carefully planned and designed. The combination of tinted or transparent panels at top and solid panels in green tone at the bottom could allow the daylight to pass through and lighten the visual impact avoiding blockage of view and potential enclosure effects, and also helps to reduce the monotonous looking and merge with its surroundings. The form and color of highway structures and columns are also streamlined to reduce monotonous and bulkiness. Appropriate plant species are proposed underneath the elevated road to maximize greening effect. Due consideration shall be given to the selection of appropriate plant species on shade-tolerance, hardiness and headroom of the structure above.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation (OM1) and Visually pleasing aesthetic treatment on noise barriers (OM6), it is considered that the proposed elevated road with noise barriers are visually compatible with the adjacent roadside landscape and visual setting of the area;
· Viewpoint VP02 near the entrance of Hong Kong Heritage Museum which is an at-grade view approximately 50m from the proposed works. It illustrates the potential landscape and visual impact due to the proposed elevated roads outside the Hong Kong Heritage Museum in a close distance. The level of elevated road is sensitively designed to avoid disturbance to the flight path of ardeids.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation (CM1) and Aesthetically pleasing design for highways structures (OM7) e.g. application of texture and finishes, it is considered that the proposed elevated road is visually compatible with the adjacent roadside landscape and visual setting of the area;
· Viewpoint VP03 on the footbridge near Sha Tin Government Secondary School which is an at-grade view approximately 230m from the proposed works. It illustrates the potential landscape and visual impact due to the proposed bridges with semi-noise enclosures near the Riverpark in a distant view from the West; The layout and appearance of the noise barriers have been carefully planned and designed. The combination of tinted or transparent panels at top and solid panels in green tone at the bottom could allow the daylight to pass through and lighten the visual impact avoiding blockage of view and potential enclosure effects, and also helps to reduce the monotonous looking and merge with its surroundings. The extent and height of the noise barrier across the Shing Mun River Channel are sensitively designed to minimize disturbance to the flight path of ardeids. In particular, the existing vegetation in the ardeid night roosting sites along Shing Mun River Channel identified in Ecological section of this EIA Report shall be preserved to minimize disturbance to the ardeids.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation (CM1), Visually pleasing aesthetic treatment on noise enclosures (OM6) and Aesthetically pleasing design for highways structures (OM7), it is considered that the visual impact from the noise barrier is unavoidable but already minimized to an acceptable level through practical mitigation measures on the noise barrier design to blend in with the adjacent riverside landscape and visual setting of the area;
· Viewpoint VP04 on the footbridge near Sha Tin Park which is an at-grade view approximately 160m from the proposed works illustrating the potential landscape and visual impact due to the proposed bridges with noise semi-enclosures and proposed noise barriers outside Hong Kong Heritage Museum viewing from the East; The layout and appearance of the noise barriers have been carefully planned and designed. The combination of tinted or transparent panels at top and solid panels in green tone at the bottom could allow the daylight to pass through and lighten the visual impact avoiding blockage of view and potential enclosure effects, and also helps to reduce the monotonous looking and merge with its surroundings. The extent and height of the noise barrier across the Shing Mun River Channel are sensitively designed to minimize disturbance to the flight path of ardeids.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation (CM1), Reinstatement of Affected Watercourses (CM8), Visually pleasing aesthetic treatment on noise enclosures (OM6) and Aesthetically pleasing design for highways structures (OM7), it is considered that the visual impact from the proposed bridges with noise semi-enclosures and proposed noise barriers outside Hong Kong Heritage Museum is unavoidable but already minimized to an acceptable level through practical mitigation measures on the noise barrier design to blend in with the adjacent riverside landscape and visual setting of the area;
· Viewpoint VP05 along Tai Chung Kiu Road near Tsang Tai Uk Recreation Ground which is an at-grade view approximately 60m from the proposed works illustrating the potential landscape and visual impact due to the proposed depressed roads with noise semi-enclosure and the new pedestrian-cum-cyclist bridge in a close distance. The layout and massing of the new pedestrian-cum-cyclist bridge and noise semi-enclosure have been carefully planned and designed. Application of texture and finishes to the pedestrian footbridge increase aesthetical impact. The green colours and transparent panels design of noise semi-enclosure avoid adverse effects and also helps to blend in with the proposed screen planting along the noise semi-enclosure upon the establishment of the proposed planting.
With the implementation of proposed mitigation measures such as Compensatory Planting for Loss of Existing Trees (OM1), Maximization of Roadside Planting (OM4), Visually pleasing aesthetic treatment on noise barriers and noise enclosures (OM6) and Aesthetically pleasing design for footbridges (OM7), it is considered that the proposed depressed roads with noise semi-enclosure and the new pedestrian-cum-cyclist bridge are visually compatible with the adjacent riverside landscape and visual setting of the area;
· Viewpoint VP06 at Lion Rock Country Park near Sha Tin Road which is an elevated view approximately 100m from the proposed works. It illustrates the potential landscape and visual impact due to the proposed depressed roads and underpass in Sha Tin Tau overlooking at a level of about 70mPD. Extensive greenery buffer has been provided along the roadside and on the roof of the underpass road for compensate the loss of existing abandoned farmland. Native tree species will be proposed to create green fingers linking to the greenery hillside of the Lion Rock County Park nearby.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation (CM1), Reinstatement of Temporarily Disturbed Landscape Areas (CM7), Compensatory Planting for Loss of Existing Trees (OM1), Landscape Treatment on Slopes (OM2), Provision of Screen Planting (OM3) and Maximization of Roadside Planting (OM4), it is considered that the proposed elevated road with noise barriers are visually compatible with the adjacent roadside landscape and visual setting of the area;

9.9.32 As a whole, the substantial visual impact on immediately adjacent VSRs (i.e. R-05, R-06 and I-07) who have a full overview of the above ground structures of the Project, after full implementation of the proposed mitigation measures, would be reduced to moderate residual impact during construction, and slight residual impact on day 1 of operation. Except R-05, the other VSRs (i.e. R-06 and I-07) would eventually diminished as insubstantial residual impact when the proposed landscape works become mature during year 10 of operation.
9.9.33 There would be moderate residual visual impact during construction on adjacent VSRs who are close to the Project (i.e. R-03, R-04, I-03, I-04, I-06, O-01, O-03, O-04) or overviewing at a higher level (i.e. O-05). It is predicted the residual impact on these VSRs would be reduced to slight on day 1 of operation. Except R-03, I-03, I-04 and O-01, the other VSRs (i.e. R-04, I-06, O-03 and O-04) would further diminished as insubstantial when the proposed landscape works become mature during year 10 of operation.
9.9.34 There would be slight residual impact during construction and day 1 of operation on VSRs further away (i.e. R-01 and I-05), VSR at low level who are close to the Project (i.e. I-01) and VSR with low sensitivity (i.e. W-01). It is predicted the residual impact on these VSRs (except T-06) would be reduced to insubstantial when the proposed landscape works become mature during year 10 of operation.
9.9.35 For the travelling VSRs, there would be slight residual impact during construction and day 1 of operation on VSRs along the roads with construction works (i.e. T-01, T-03 and T-06) and slight residual impact only during construction for VSRs further away from the construction works (i.e. T-02, T-04 and T-05). It is predicted the residual impact on these VSRs would be reduced to insubstantial when the proposed landscape works become mature during year 10 of operation.
9.9.36 For those VSRs (i.e. R-03, I-03, I-04 and O-01) viewing to the proposed bridge with noise semi- enclosure at Shing Mun River Channel of VP3, VP4 and VP11, and the two VSRs (i.e. R-05 and T-06) viewing to the full noise enclosure along Sha Tin Road of VP8, there are still slight residual visual impacts upon day 1 of operation and year 10 of operation.
9.9.37 It is predicted that there would be insubstantial residual visual impact during construction and operation on long distant VSRs (i.e. I-02 and I-08) or VSRs with only glimpse view to the above ground structures of the Project (i.e. R-02 and O-02).

9.10.1 Construction of the Project is scheduled to commence in 2023 Q4 tentatively. The construction works will take approximately 5 years for completion and the targeted commissioning date of the Project will be in Q3 2028 tentatively. According to Section 2, the following projects in the vicinity are likely to be constructed/operated concurrently with the Project based on the available information obtained during the course of the EIA Study:
·
Widening of Tai Po Road (Sha
Tin Section) by CEDD;
· Improvement of Lion Rock Tunnel (LRT) by HyD; and
·
Revitalization of Tai Wai
Nullah by DSD.
9.10.2 The construction period of “Widening of Tai Po Road (Sha Tin Section)” would not overlap with the proposed footprint of T4 at the Tai Po Road (Sha Tin Section) south of Tin Liu, thus no significant cumulative impacts are anticipated during the construction phase. During the operation phase of the Tai Po Road (Sha Tin Section), no cumulative landscape and visual impact would be anticipated as the boundary of two projects are not overlapped and the view to the two projects are blocked by either existing road corridor or the residential development near Scenery Court.
9.10.3 Based on the latest available information, the tentative construction work of the entire Improvement of LRT project will be commenced in 2025 for completion by 2036. As the road widening works of LRT Road at the section near Sun Tin Wai Estate/Fung Shing Court undertaking by LRT Project will commence in December 2028 while the construction of the Project will be completed in September 2028, no potential cumulative impact due to the construction of the Improvement of LRT project will be anticipated in this EIA Study. With proper implementation of mitigation measures such as preservation of existing vegetation, compensatory planting in Sha Tin Tau, re-provision of affected open space in Sha Tin Tau Sitting-out Area and aesthetically pleasing design of noise enclosure near Pok Hong Estate, no landscape and visual cumulative impacts will be anticipated.
9.10.4 The construction works of Revitalisation of Tai Wai Nullah are tentatively scheduled to commence in Q3 2024 for completion by Q4 2029, which will overlap with the tentative construction programme of the Project. A small portion of site area of the two Projects in Tai Wai Nullah near Shing Mun Tunnel Road is overlapped. Slight cumulative landscape and visual impact during construction is anticipated for the foundation works for the Revised Trunk Road T4 viaducts in this area. The tentative construction programme and works at the interface area between the two projects could be arranged efficiently through close liaison between DSD’s and CEDD’s contractors of the Revitalisation of Tai Wai Nullah project and the Project respectively in order to avoid construction works of respective works contracts to be carried out concurrently at the same interfacing areas. No significant cumulative impact is expected upon operation in view of the proposed elevated road of T4 would blend in with the existing road corridor at high elevation, and the proposed revitalization works of Tai Wai Nullah project is expected to have benefit to the at-grade landscape and visual context upon operation. With proper implementation of mitigation measures (e.g. preservation of existing vegetation, control of night-time lighting glare, erection of decorative screen hoarding and reinstatement of temporarily disturbed landscape area and watercourse) as recommended in the EIA report, the landscape and visual cumulative impacts would be minimized to an acceptable level.
9.11.1 The detailed landscape and engineering design of the Project shall be undertaken so as to ensure compliance with the landscape and visual mitigation measures described in Section 9.8.
9.11.2 Implementation of the recommended mitigation measures would be regularly audited during construction phase. Details of environmental monitoring and audit (EM&A) requirement are discussed in the separate EM&A Manual.
9.12.2 Based on the broad-brush tree estimate with approximately 3,685 nos. of trees surveyed, approximate 1,051 nos. of existing trees including 13 nos. of trees of particular interest will be unavoidably affected by the Project. All the 6 nos. of registered OVTs in the vicinity of the project boundary will be retained in-situ and not be affected by the Project. One tree of particular interest Ficus benjamina with high amenity value and large size outside the Hong Kong Heritage Museum will be unavoidably affected and tree transplanting is proposed, subject to the review on technical feasibility and sensitivity analysis in detail design stage and further advice from the existing and future tree maintenance departments. In case removal of the subject tree of particular interest is considered unavoidable in later stage, the procedures as set out in Section 2.6 of the TRAM Guidelines and suitable initiatives to commemorate the tree (e.g. replanting) shall be considered in accordance with Para. 26 (d) of DEVB TC(W) No. 4/2020. For the remaining approximate 1,050 nos. of affected trees, tree felling will be proposed. The major affected tree species in the individual tree survey include Ailanthus fordii, Canthium dicoccum, Ficus benjamina and Pterocarpus indicus. The major affected tree species in tree group survey include Acacia confusa, Bridelia tomentosa, Casuarina equisetifolia, Eucalyptus tereticornis, Ficus microcarpa, Melia azedarach, Polyspora axillaris, Sterculia lanceolata and Schima superba.
9.12.3 Under the proposed scheme for the Project, opportunities for tree compensation within the Project boundary has been fully explored and incorporated in the proposed mitigation measures as much as practicable. Due to the limited site areas within developed built-up areas in Sha Tin, tree compensatory planting in roadside and flat areas and woodland mix planting on slopes are proposed subject to the gradient of the proposed new slopes. A minimum of 250 heavy standard trees will be proposed at roadside flat areas, at the re-provided Sha Tin Tau Village Sitting-out Area and at the planting areas of elevated roads with shade-tolerant tree species. The proposed species are commonly used in urban environment so as to reinstate and enhance the surrounding landscape value. Reference could be made to Greening Master Plan issued by CEDD and Street Tree Selection Guide promulgated by DEVB. Total area of approximate 11,300m2 will be proposed as compensatory woodland mix planting with approximately 3,400 nos. of tree whips to be planted. Mix of native tree species will be proposed in reference to Guiding Principles on Use of Native Plant Species in Public Works Projects promulgated by DEVB to improve the vegetation diversity, enhance ecological value and re-creation of vegetation habitat particular for areas adjoining the Lion Rock Country Park.
9.12.4 With the implementation of proposed mitigation measures, it is predicted that there would be moderate to slight residual impact on existing landscape resources (LR-1.1, LR-1.2, LR-1.3, LR-1.4, LR-2.2, LR-2.3, LR-3.5, LR-3.6, LR-4.2, LR-5.2, LR-5.3 and LR-5.4) during construction, and slight to insubstantial impact on day 1 of operation. The residual impact on these landscape resources would be further reduced to insubstantial when the proposed compensatory planting, buffer planting and woodland mix planting become mature in year 10 of operation.
9.12.5 It is predicted that there would be moderate to slight residual impact on landscape character areas (LCA-1.2, LCA-2.1, LCA-2.2, LCA-3.1, LCA-3.2, LCA-4.1, LCA-5.1, LCA-8.1 and LCA-8.3) during construction and slight impact on day 1 of operation. The residual impact on these landscape character areas would be further reduced to insubstantial when the proposed compensatory planting, buffer planting and woodland mix planting become mature in year 10 of operation.
9.12.6 Regarding mitigated visual impact, it is predicted that there would be moderate residual impact on residential VSRs in R-03, R-04, R-05 and R-06, institutional VSRs in I-03, I-04, I-06 and I-07, recreational VSR in O-01, O-03, O-04 and O-05, and slight residual impact on residential VSR in R-01, institutional VSRs in I-01 and I-05, traveling VSRs in T-01, T-02, T-03, T-04, T-05 and T-06, and industrial VSR W-01 during construction. The residual impact on most of these VSRs would be slight on day 1 of operation and be further reduced to insubstantial when the proposed tree planting becomes mature in year 10 of operation. For those VSRs (i.e. R-03, I-03, I-04 and O-01) viewing to the proposed bridge with noise semi-enclosure at Shing Mun River Channel of VP3, VP4 and VP11, and the two VSRs (i.e. R-05 and T-06) viewing to the full noise enclosure along Sha Tin Road of VP8, there are still slight residual visual impacts upon day 1 of operation and year 10 of operation. There would be insubstantial residual impact on other VSRs within the visual envelope during the construction and operation of the Project.
9.12.7 In sum, it is considered that the residual landscape and visual impact is acceptable with mitigation measures implemented during construction and operation phases.
