· 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.

· 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.
· 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:
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.
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.
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:
1. the compatibility with the surrounding landscape;
2. the duration of the impact;
3. the reversibility of the impact;
4. the scale of the impact and distance of the source of impact from the viewer; and
5. 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.

Approximate 12,140m.sq. (3% of this LR) will be affected, in which 2,250m.sq. within Lion Rock Country Park will be permanently affected.
Approximate 532 nos. of existing trees are being affected by modification and construction of the tunnel administration area, tunnel portal area, road widening, noise barriers/semi-enclosures and associated slope works. Among them, approximately 9 trees within Lion Rock Country Park are unavoidably affected mainly by the modification of toll plaza and tunnel administration area. One no. of tree of particular interest Ficus microcarpa with DBH over 1m will also fall within the temporary works area near the Kak Tin area. The temporary works shall be carefully arranged to perverse the tree where technically feasible.
Although only 3% area of this LR is affected, magnitude of change is rated as intermediate in view of the relatively large quantity of tree affected and involving country park area. |

· Viewpoint VP01 view from Lung Cheung Road is approximately 30m from the proposed works. It illustrates the potential landscape and visual impact due to the proposed bridge and road widening in Kowloon side. The alignment of proposed bridge is carefully designed to minimize the works extent along existing road. The form and color of highway structures and columns are also streamlined to reduce monotonous and bulkiness. Buffer planting with appropriate species is proposed adjoining the proposed columns to screen and soften the structures.
With the implementation of proposed mitigation measures such as Control of Night-time Lighting Glare, Erection of Decorative Screen Hoarding, Compensatory Tree Planting for Loss of Existing Trees, Aesthetically pleasing design of Highways Structures and Slope Associated Structures and Provision of Buffer Planting / Roadside Planting, it is considered that the proposed bridge and road widening are visually compatible with the adjacent roadside landscape and visual setting of the area;
· Viewpoint VP02 Portal View of Kowloon Side is within 5m from the proposed works to illustrate the potential landscape and visual impact due to the proposed ventilation building and associated slope works near the portal area of Kowloon side. The form and layout of proposed ventilation building and portal structure are aesthetically designed to reduce the bulkiness. The ventilation building is also carefully sited at the recessed area screened by the proposed slope. Appropriate greenings in the form of native shrub and groundcover planting are proposed on the associated slopes in the portal area to maximize the greening effect.
With the implementation of proposed mitigation measures such as Aesthetically pleasing design of Aboveground Structures, Aesthetically pleasing design of Highways Structures and Slope Associated Structures, Provision of Green Roof and Greening Works on Slopes and associated structures, it is considered that the proposed ventilation building and associated slope works near the portal area of Kowloon side can blend in with the surrounding greenery context;
· Viewpoint VP03 Toll Plaza View of Tai Wai Side is within 5m from the proposed works to illustrate the potential landscape and visual impact due to the works at the proposed tunnel administration building and the re-arrangement of toll plaza area. The form and façade of proposed ventilation building are aesthetically designed to reduce the monotonous looking and provide visual interest to the toll plaza area. Appropriate greenings in the form of native shrub and groundcover planting are proposed on the associated slopes to echo with the green context of adjoining Lion Rock Country Park. At grade tree planting will be provided where possible to further maximize greenery and soften the proposed building and structure.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation, Control of Night-time Lighting Glare, Minimize the Direct Conflict with Lion Rock Country Park, Aesthetically pleasing design of Aboveground Structures, Aesthetically pleasing design of Highways Structures and Slope Associated Structures, Provision of Green Roof and Greening Works on Slopes and associated structures, it is considered that the visual impact from the re-arrangement of toll plaza area and the tunnel administration building is unavoidable but already minimized through practical mitigation measures of the slope and roadside planting and the aesthetic treatment of the building façade;
· Viewpoint VP04 Amah Rock View to Tai Wai is at a level of about 250mPD and approximately 320m from the proposed works to illustrate the potential landscape and visual impact due to the proposed road improvement works and re-arrangement of toll plaza area overlooking to Tai Wai at an elevated view. The rearrangement of toll plaza area is visually coherent with the existing road context from this distant viewpoint, hence the unmitigated visual impact is slight. Mitigation measures such as Preservation of Existing Vegetation, Control of Night-time Lighting Glare, Compensatory Tree Planting for Loss of Existing Trees and Aesthetically pleasing design of footbridges can be provided for further ameliorating the view;
· Viewpoint VP05 Amah Rock View to Sha Tin is at a level of about 250mPD and approximately 320m from the proposed works to illustrate the potential landscape and visual impact due to the proposed road improvement works and noise barriers / semi-enclosures overlooking to Sha Tin townscape at an elevated view. The proposed semi-noise enclosure at the Hung Mui Kuk junction are aligned with the existing road context from this distant viewpoint, hence the unmitigated visual impact is slight. Mitigation measures such as Preservation of Existing Vegetation, Control of Night-time Lighting Glare, Compensatory Woodland Mix Planting on Soil Slopes and Aesthetically pleasing design of footbridges, noise barriers and semi-noise enclosures can be provided for further ameliorating the townscape view;
· Viewpoint VP06 Entrance of Hung Mui Kuk Nature Trail is right next to the proposed works to illustrate the potential landscape and visual impact due to the proposed road widening works and semi-noise enclosures at a close distance. Noise mitigation structures are unavoidable in view of the close distance from residential VSR at World-Wide Gardens. Part of the entrance area of Hung Mui Kuk Nature Trail will be the temporary works area during construction and the existing staircase to the entrance area will be re-provided for the recreational users. To minimize visual disturbance of the recreational VSRs to enjoy the countryside and the barbeque site during construction phase, decorative screen hoarding with appropriate greening design in the form of vertical greening or portable planter along the hoarding will be provided. The temporary works area will be confined to the entrance of Hung Mui Kuk Nature Trail, while the existing picnic site and toilet would not be affected.
To enhance the visual compatibility of the proposed road widening and noise semi-enclosure during operation, the layout and appearance of the noise semi-enclosure have been carefully planned and designed. The combination of tinted or transparent panels at top and solid panels at the bottom could allow the daylight to pass through and lighten the visual impact. The opening of semi-noise enclosure facing entrance of Hung Mui Kuk Nature Trail with appropriate buffer planting and low panels in light green color, the massing and enclosure effect of the structure can be soften and scaled down to more coherence with adjoining natural setting.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation, Control of Night-time Lighting Glare, Erection of Decorative Screen Hoarding, Management of Construction Activities and Facilities, Reinstatement of Temporarily Disturbed Landscape Areas, Minimize the Direct Conflict with Lion Rock Country Park, Aesthetically pleasing design of Highways Structures and Slope Associated Structures, Aesthetically pleasing design of footbridges, noise barriers and semi-noise enclosures and Provision of Buffer Planting / Roadside Planting, it is considered that the visual impact from the semi-noise enclosure is unavoidable but already minimized through practical mitigation measures on the noise semi-enclosure design and the buffer planting along the structure;
· Viewpoint VP07 View to World-Wide Gardens is approximately 20m from the proposed works to illustrate the potential landscape and visual impact due to the proposed semi-noise enclosures along the LRT Road and slip road. Noise mitigation structures are unavoidable in view of the close distance from residential VSR at World-Wide Gardens. The layout and appearance of the noise semi-enclosure 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, hence reduce the monotonous looking and lighten the visual impact. Provision of compensatory tree plantings at the road verge area greatly soften the hard structures behind and helps to blend in with its surroundings vegetated slopes.
With the implementation of proposed mitigation measures such as Control of Night-time Lighting Glare, Erection of Decorative Screen Hoarding, Compensatory Woodland Mix Planting on Soil Slopes and Aesthetically pleasing design of footbridges, noise barriers and semi-noise enclosures, it is considered that the proposed semi-noise enclosures with appropriate tree plantings are visually compatible with the adjacent landscape and visual setting of the area; and
· Viewpoint VP08 View from Sun Tin Wai Estate is on the footbridge right above the proposed works to illustrate the potential landscape and visual impact due to the proposed road widening with re-provision of footbridge, noise semi-enclosure and associated slope works overlooking at a close distance. Noise mitigation structures are unavoidable in view of the close distance from residential VSR at Sun Tin Wai Estate. 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. The existing footbridge will be demolished during the road widening works and re-provided at the same location. The roof and upper part of the re-provided footbridge would compose of transparent panels and/or openings to reduce the bulkiness, catch more sunlight and enhance the outlook.
With the implementation of proposed mitigation measures such as Preservation of Existing Vegetation, Control of Night-time Lighting Glare, Erection of Decorative Screen Hoarding, Reinstatement of Temporarily Disturbed Landscape Areas, Aesthetically pleasing design of Highways Structures and Slope Associated Structures, and Aesthetically pleasing design of footbridges, noise barriers and semi-noise enclosures , it is considered that the visual impact from the semi-noise enclosures is unavoidable but already minimized through practical mitigation measures on the noise barrier design and slope greening along the road to blend in with the adjacent landscape and visual setting of the area.
