Table 8.6.3 Proposed Construction Phase Mitigation Measures | |||||||||||||||||||||||||||||||||||||||||||||||||||

|||||||||||||||||||||||||||||||||||||||||||||||||||
8.7 | Operational Impacts | ||||||||||||||||||||||||||||||||||||||||||||||||||
Potential Sources of Impacts in the Operational Phase 8.7.1 The extent of works for the proposed development at Whitehead is
indicated in the site layout plans, and again within the Landscape Mitigation
Measures Plans Figures 8.21 and 8.22. The sources of impacts of the project
at the operational stage would be:
Nature of Landscape Impacts in the Operational Phase 8.7.2 The impact on the site geology (solid and drift), through the development of buildings and roads would be permanent and is considered to be of low magnitude. Similarly the impact on existing topography due to the development would be permanent, and again the magnitude is considered to be small. 8.7.3 As the extent of the development would be the same as the area of clearance during the construction phase, the magnitude of the direct impact on areas of secondary woodland would remain as intermediate. Similarly the magnitude of impact on areas of existing agricultural land would remain as large. 8.7.4 The stripping and re-use of existing soils from within several
areas within the study area, would mean the magnitude of the impact on
this landscape resource might be considered to be small by completion
of the development. 8.7.5 There will be a negative impact during operational phase on most of the LCAs in the Study Area. However, in the case of LCA1 - Former Whitehead Detention Centre and LCA 6 - Wu Kai Sha Station Development Site, these landscapes are currently so degraded and incoherent that the new development will not have a very significant impact on their character and after maturing of mitigation measures, these landscapes will have a different character so that the significance of impacts on landscape character will be negligible. 8.7.6 In the case of other LCAs, such as LCA4, there will be direct and indirect impacts from loss of vegetation and the presence of roads and built structures. This will result in significant new features in the landscape and long term inpacts will be significant. 8.7.7 In other LCAs (LCAs 2,3 and 5), there will be indirect impacts
as a result of the project works, such as the presence of new tower blocks,
although the Works themselves will not take place within the LCAs. The
presence of these man-made structures so close to these landscapes will
contrast unfavourably with the existing natural qualities of these LCAs
and resulting impacts will be significant, especially on LCA2 (Whitehead
Penisula Coast) and on LCA5 (Starfish Bay). Nature of Visual Impacts in the Operational Phase Residential 8.7.8 All views to north and east of the villages of To Tau and Wu Kai Sha would be obstructed by proposed the buildings resulting in considerable permanent change to the views. 8.7.9 Residents of Monte Vista would have their existing views of Tolo Harbour fully obstructed by the Wu Kai Sha Station Development. Given the proximity and mass of the proposed development, the magnitude of change in the view would be large and the impact substantial. The proposed mitigation measures are not likely to reduce this significantly. 8.7.10 Views of residents of high-rise developments in eastern Ma On Shan, would similarly be partially obstructed by the buildings, especially those living in Lee On Estate/Kam Lung Court, although for other residents such as those in Saddle Ridge Court, Villa Athena and Villa Oceania/Bayshore Towers, this would constitute a smaller change in their more expansive view. The landscape treatment of the site and architectural treatment of the buildings is likely to tone down their impact slightly, but there would be a considerable permanent change in their views. 8.7.11 Views of residents of medium and low rise blocks at Cheung Muk Tau; Sai O; Tseung Kwan Lei; Kwun Hang; Nai Chung to the east of the site, would similarly be obstructed. This is likely to result in only a minor change in their views, although the architectural treatment of the buildings is not likely to tone down the impact further. Planting along the site boundary would however reduce the impact on low level views. 8.7.12 The development would be clearly visible long range views of the development across Tolo Harbour from the low and medium rise residential settlements at on the hills above Tolo Harbour, at Ma Liu Shui/Kon Hang/ Tsiu Hang/ Tai Po Kau San Wai/ Tai Po Kau Lo Wai/ Lai Chi Hang/ Ha Wong Yi Au, but seen in the context of the surrounding urban development, the change in view is likely to be only slight, although the proposed architectural treatment of the buildings would not reduce this significantly. 8.7.13 Upon completion the new high-rise buildings would be seen in low level, medium distance views from Sham Chung across Three Fathoms Cove, in silhouette and against the sky and a backdrop of distant hills. Resulting in a slight permanent change in their expansive views. The proposed architectural treatment of the buildings would not reduce this significantly. 8.7.14 The noise barriers / semi-enclosure for Road T7 are covered by
EPAEP-119/2001 and are under construction. Some amendments have been proposed
under the Road T7 project and are being considered by EPD. Semi-enclosure
has now been proposed along the slip road immediately to the east of Wu
Kai Sha Staion Development. The semi-enclosure is much lower in elevation
than the future residential flats of the Wu Kai Sha Station Development
and would not pose any significant visual impact on the residents. A cross-section
showing the relative positive of the Wu Kai Sha Station Development and
the adjacent Road T7 slip road is shown in Annex H. 8.7.15 The tower blocks would obstruct views to the west of users of medium rise educational blocks at Li Po Chun United World College, resulting in a medium change in their view. Although the architectural treatment of the buildings is not likely to tone down the impact further as they would be seen in silhouette and against the sky and a backdrop of distant hills, planting along the site boundary would reduce the impact on low level views. 8.7.16 There would be a slight but permanent change in the views from low and medium rise blocks at the Chinese University where the new buildings would be seen in the context of the surrounding urban development. on the west side of Tolo Harbour. Recreational Users 8.7.17 There would be significant changes in the views for recreational users of Chinese YMCA of HK Wu Kai Sha Youth Village, and further to the west, Ma On Shan Park / Ma On Shan Swimming Pool where the new buildings would obstruct views to north and east. Architectural treatment of the buildings will tone down the impact, and planting along the site boundary would further mitigate the impact on low level views. 8.7.18 There would be slight changes in the views for recreational users of Ma On Shan Country Park where the new buildings would push the extent of urban development further to the north. Current views of the coastline around the Whitehead site would be lost, locally changing the defining elements for Tolo Harbour from a natural edge to an urban one. Planting within the site would mitigate the impact to some extent but permanent change in view is predicted. 8.7.19 Recreational users of the Plover Cove / Plover Cove Reservoir, would have direct views from the dam of the new buildings, and although seen against urban Ma On Shan, would still constitute a permanent change in the quality of the view. Architectural treatment of the buildings will tone down the impact, and planting along the site boundary would further mitigate the impact on low level views to some extent. Travellers 8.7.20 Permanent changes in brief, close range views to the north are
anticipated for motorists / travellers on Sai Sha Road. Architectural
treatment of the road structures of Road D1 and the elevated deck, pier
and abutment structures of the slip roads linking to Road T7, as well
as the treatment of boundary elements, and high rise towers and screen
planting on the southern side of the site would reduce the scale of the
change. Mitigation Measures During the Operation Phase 8.7.21 Landscape and visual mitigation measures which should be incorporated within the permanent landscape design to ameliorate impacts caused during the operation phase are described in Table 8.7.3, together with the proposed funding, implementation, and management and maintenance agencies. The mitigation measures are illustrated in Figure 8.22. 8.7.22 Allowance for the measures listed should be made in the detailed design of the development (or any part thereof) and should be fully implemented as part of the construction works so that they are in place at the date of completion. However, it should be noted that the full effect of the soft landscape mitigation measures (woodland tree and shrub planting) would not be appreciated for several years. Prediction of Significance of Landscape Impacts in the Operation Phase 8.7.23 An assessment of the potential significance of the landscape impacts during the operational phase, before and after mitigation is provided in Table 8.7.1, and illustrated in Figure 8.13B. This follows the methodology outlined in Section 8.3.3 and assumes that the appropriate mitigation measures identified in Table 8.7.3 had been fully implemented. 8.7.24 Impacts on LCAs during the construction phase are shown in Figures 8.13E and F. Prediction of Significance of Visual Impacts in the Operation Phase 8.7.25 An assessment of the potential significance of the visual impacts during the operational phase, before and after mitigation is provided in Table 8.7.2, and illustrated in Figure 8.14B. This follows the methodology outlined in Section 8.3.3 and assumes that the appropriate mitigation measures identified in Table 8.7.3 had been fully implemented. 8.7.26 Illustrations of the likely impact on key views of the proposed
development at Year 1 are given in version C of the photomontages in Figures
8.15 to 8.20. Table 8.7.1 Significance of Landscape Impacts in Operational Phase |

8.8 | Residual Impacts | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
8.8.1 Residual impacts are those that
persist after the mitigation planting works have become fully effective.
This is assumed to be at a point 10 (ten) years after the date of completion.
The residual impacts represent the long term effect on the landscape and
visual context of the area that would be a direct consequence of the proposed
development.
Prediction of Significance of Residual Landscape Impacts 8.8.2 The significance of residual landscape impacts is provided in Table 8.7.1, and illustrated in Figure 8.13C. This assumes that the appropriate mitigation measures identified in Table 8.7.3 would be implemented, and that the full effect of the soft landscape mitigation measures had been realised. Prediction of Significance of Residual Visual Impacts 8.8.3 The significance of residual visual impacts is provided in Table
8.7.2, and illustrated in Figure 8.14C. This assumes that the appropriate
mitigation measures identified in Table 8.7.3 would be implemented, and
that the full effect of the soft landscape mitigation measures had been
realised. Illustrations of the likely impact on key views of the proposed
development at Year 10 are given in version D of the photomontages in
Figures 8.15 to 8.20. |

8.9 | Conclusions | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
8.9.1 The proposed development would result in significant impacts on existing landscape resources on site, principally areas of plantation, secondary woodland, and existing natural soils. These would need to be cleared to make way for the proposed development, although around the headland the proposed land uses would be able to incorporate existing woodland and soils into the design, thereby reducing actual losses. Landscape mitigation measures include extensive woodland and landscape planting and the re-use of soil materials from site, and these would effectively reduce long term impacts on woodland/plantation and soils to slight levels. 8.9.2 Impacts on agricultural land (moderate impact) would be permanent as it would not be practical to reprovision such an element within the nature of the proposed development. 8.9.3 Impacts on key affected landscape resources are quantified below
in Table 8.9.1: |

8.9.4 Impacts on the landscape character
of the landscape will vary dramatically. The indirect impacts on the natural
and tranquil qualities of the Whitehead Peninsula Coast (LCA2) and on Starfish
Bay (LCA5) will be substantial during the construction and early years of
the development reducing to moderate at Year 10.
8.9.5 In contrast to this, the impacts on the currently degraded landscape of the former Whitehead Detention Centre and on the Wu Kai Sha Station Development site will be negligible due to the incoherent and degraded character of these landscapes. With successful and diligent implementation of landscape mitigation measures, it is possible that impacts could be negligible when they mature at Year 10. 8.9.6 Direct and indirect impacts on the landscape of surrounding villages
(LCAs 3 and 4) will be moderate during the construction period and early
years of operation, reducing to slight at Year 10. The new development
will be of a larger scale than the existing villages, but the presence
of built development in these areas will serve to offset impacts somewhat.
8.9.7 There would be significant impacts on views to north and east of the villages of To Tau and Wu Kai Sha resulting in considerable permanent change to the views. Substantial level visual impacts during construction would be reduced by architectural treatment of the buildings and proposed mass planting to moderate levels during long term operational phases. 8.9.8 There would also be a considerable permanent change in views of residents of high-rise developments in eastern Ma On Shan, resulting in a moderate visual impact during construction, reducing to slight in the long term. Recreational users of Ma On Shan Country Park would be similarly affected. 8.9.9 Relevant residents of Monte Vista would have their existing views of Tolo Harbour mostly obstructed by the Wu Kai Sha Station Development. Given the proximity and mass of the proposed development, the visual impact would be substantial. The proposed mitigation measures are not likely to reduce this significantly. 8.9.10 Residents elsewhere in eastern Ma On Shan will experience visual impacts which will affect their views of the setting of Tolo Harbour. These include residents of Lee On Estate/Kam Lung Court, residents such as those in Saddle Ridge Court, Villa Athena and Villa Oceania/Bayshore Towers who will experience moderate or slight impacts after Year 10 of operation. 8.9.11 Views of residents of medium and low rise blocks at Cheung Muk Tau, Sai O, Tseung Kwan Lei, Kwun Hang, Nai Chung to the east of the site, and users of medium rise educational blocks at Li Po Chun United World College, would similarly be affected with moderate level impacts during construction, being reduced in the long term by planting along the site boundary to slight impacts in the long term. The new high-rise buildings would be seen from Sham Chung across Three Fathoms Cove, in silhouette and against the sky and a backdrop of distant hills. Resulting in a slight permanent change in their extensive views. Recreational users of Chinese YMCA of HK Wu Kai Sha Youth Village and Ma On Shan Town Park/Swimming Pool to the west would also be affected. 8.9.12 The development would be clearly visible long range views of the development across Tolo Harbour from the low and medium rise residential settlements at on the hills above Tolo Harbour, at Ma Liu Shui/Kon Hang/ Tsiu Hang/ Tai Po Kau San Wai/ Tai Po Kau Lo Wai/ Lai Chi Hang/ Ha Wong Yi Au, buildings at the Chinese University, and recreational users of the Plover Cove / Plover Cove Reservoir. As it is seen in the context of the surrounding urban development, the change in view is likely to be only slight, although the proposed architectural treatment of the buildings would not reduce this significantly. 8.9.13 Given its scale, the proposed development would have relatively modest landscape and visual impacts. Most of the impacts could be effectively reduced by the proposed landscape mitigation measures, however it is recognised that there would be permanent changes in the extent and quality of existing landscape resources, landscape character and visually sensitive receivers. |

8.10 | Recommendation | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
8.10.1 If the development is to proceed
it is recommended that all the landscape mitigation measures described for
both the construction phase (Table 8.6.3), and the operational phase (Table
8.7.3), be adopted in full. Supplementary assessment (with mitigation proposal)
on the visual impacts is required to be prepared as necessary for the proposed
Road D1 (Schedule 2 DP) before the applicants for this respective Environmental
Permits are submitted. 8.10.2 It is further recommended that the following procedural measures be adopted :

8.11 | Acceptability of Impacts | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
8.11.1 In accordance with Annex 10, Para
1.1(c) of the EIAO TM, the landscape and visual impacts of the project under
the preliminary Preferred Development Option are assessed as being "acceptable
with mitigation measures". Para 1.1(c) states that "the impact
is acceptable with mitigation measures if there will be some adverse effects,
but these can be eliminated, reduced or offset to a large extent by specific
measures".
8.11.2 In the case of the current Project, taken as a whole, the landscape and visual impacts arising from the development can be offset to a large extent by mitigation measures. However, it is essential that these measures be well designed and implemented and that the mitigation measures be continued through to the detailed design of the buildings for the development. 8.11.3 By extention of the above, it can be assumed that the landscape
and visual impacts of the Preferred Development Option (5.0 plot ratio
for Wu Kai Sha Station Development) as a less massive visual element than
that of the Preliminary Preferred Development Option will also be acceptable
under Para 1.1(c) under the same conditions. The photomontage of the Preferred
Development Option from Monte Vista is shown on Figure 8.20B1. |
