¡P Study on Landscape Value Mapping of Hong Kong
¡P 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.
¡P 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
¡P 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. |
¡P Identification of potential sources of landscape changes. These are the various elements of the construction works and operation procedures that would generate landscape impacts:
¡P 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. |
¡P 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, 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.
¡P 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 8.1 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. |
¡P 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. |
¡P 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.
¡P 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.
¡P 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.
¡P 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.
¡P 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. |
¡P 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.
¡P Identification of potential sources of visual changes. These are the various elements of the construction works and operation that would generate visual changes.
¡P Assessment of the potential magnitude of visual changes. Factors considered include:
o the compatibility with the surrounding landscape;
o the visual obstruction
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.
¡P 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. |
¡P 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, 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.
¡P 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 8.2 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.
