Hong Kong Convention and Exhibition Centre Atrium Link Extension Environmental Impact Assessment Report 7 LANDSCAPE AND VISUAL IMPACT ASSESSMENT Introduction 7.1 This Landscape and Visual Impact Assessment (LVIA) covers the proposed Atrium Link Extension of Hong Kong Convention and Exhibition Centre (HKCEC) in Wan Chai North. The project proponent is Hong Kong Trade Development Council (TDC). This section assesses the potential landscape and visual impact due to the construction and operation of the proposed work in accordance with the Environmental Impact Assessment Ordinance (EIAO). 7.2 Existing HKCEC consists of three major components, i.e., Phase 1, Phase 2 and the Atrium Link found in between these Phases. Phase 1 is commonly known as “Old Wing” while Phase 2 as “New Wing”. Local people of Hong Kong are more familiar with these terms and this LVIA will use them to serve better communication. Project Description 7.3 Figure 7.1 shows an existing aerial view of HKCEC in Wan Chai North and the developments along the waterfront of Victoria Harbour. The existing HKCEC Atrium Link joins up the “New Wing” and the “Old Wing”. The proposed works involve the expansion of the existing Exhibition Halls to provide additional floor spaces to accommodate large-scale events. Figures in Appendix 7.1 show the master layout and architectural design of the proposed works. Full description and justification on the need on the extension project is provided in Section 2 of this EIA report. Review of Planning and Development Control Framework 7.4 A review of the existing and planned development framework for the proposed works and for the surroundings has been considered. It aims to identify issues for the neighbouring planned land uses, to identify potential resources and sensitive receivers, and to ensure a high compatibility between the proposed project and the surroundings. 7.5 Wan Chai North Outline Zoning Plan (OZP) No. S/H25/1 has been examined. The area near the waterfront is dominated by patches of Other Specified Use (OU), suggesting the sensitive nature and planning of the area. The Plan shows possible developments, including the provision of Open Spaces (O) to the east and to the west of the existing HKCEC “New Wing”. It also shows the proposed relocation of Wan Chai Ferry Pier and the planning of a large Comprehensive Development Area (CDA) on the existing bus terminal to the south of Wan Chai Ferry Pier. Although the Plan has been made statutory under the Town Planning Ordinance, it shall by no means be considered a consolidated plan due to the strong public criticisms and juridical reviews in recent years. Intended Final 7-1 Hong Kong Convention and Exhibition Centre Atrium Link Extension Environmental Impact Assessment Report land use pattern extracted from the Plan is shown on Figure 7.2. 7.6 The existing area of HKCEC Atrium Link has been zoned as OU. Part of the proposed Atrium Link Extension falls within the area designated as ‘Road’ on the Wai Chai North OZP which requires planning permission from the Town Planning Board (TPB) according to Section 16 of the Town Planning Ordinance. An application to TPB has already been approved earlier to expand the area to suit the intended Atrium Link Extension. 7.7 Major waterfront development projects have been previously planned along the waterfront near Wan Chai, including: - Wan Chai Development Phase II (WDII) - Central Wan Chai Bypass (CWB) and Road P2 These projects are somewhat interlinked because they require a prerequisite of consolidated planning of reclamation from Central to Causeway Bay. With strong objection on reclamation and support for harbour protection from the public in recent years, these developments are still under review by the authorities. There is some chance that these developments will not be constructed after several years, when the construction of the proposed HKCEC Atrium Link Extension is already completed. Nevertheless, this report takes the approach on what has been already planned by the Government years ago, assuming the construction of these developments commences when the proposed ALE is nearly completed. Environmental Legislation and Standards 7.8 The followings are considered: • Wan Chai North Outline Zoning Plan (OZP) No. S/H25/1 and the Town Planning Ordinance • Environmental Impact Assessment Ordinance, Annexes 10 and 18 of Environmental Impact Assessment Ordinance (EIAO) Technical Memorandum and EIAO Guidance Note No. 8/2002. • Protection of the Harbour Ordinance • Metroplan (Oct 1991) • Central & Wan Chai Reclamation : Development of Urban Design Parameters (DUDPS) • Hong Kong Island West Development Statement (HKWDS) • Government General Regulation 740 –sets out restrictions on the preservation and felling of trees in Hong Kong Final 7-2 Hong Kong Convention and Exhibition Centre Atrium Link Extension Environmental Impact Assessment Report • ETWBTC No. 29/2004 Registration of Old and Valuable Trees and Guidelines for their Preservation – provides priority protection to the trees in the Register. Furthermore, the Government has already put in place a comprehensive range of administrative and legislative measures to preserve trees on Government land. • ETWBTC No. 2/2004 Maintenance of Vegetation and Hard Landscape Features – sets out the government departmental responsibilities for maintenance of vegetation and hard landscape features. • ETWBTC No. 14/2002 Management and Maintenance of Natural Vegetation and Landscape Works, and Tree Preservation – defines and outlines the management and maintenance responsibilities for natural vegetation and landscape works, and the authorities for tree preservation and felling. • ETWBTC No. 7/2002 Tree planting in Public Works – affirms the advocated policy on tree planting which adopts a flexible and balanced approach in the planning and design of public works. • Hong Kong Planning Standards and Guidelines, Section 4: Recreation, Open Space and Greening and Section 11: Urban Design Guidelines – outlines the guidelines to be considered for open space design, greening and urban design. • Technical Reports of Landscape Value Mapping in Hong Kong by Planning Department – establishes the essential landscape baseline information which provides a systematic reference framework to facilitate landscape assessment and broad environmental assessment of major projects at territorial level. Methodology of Assessment of Landscape Impacts 7.9 The assessment of landscape impacts has adopted the following process: • Identification of the baseline Landscape Resources (LR) and Landscape Character Area (LCA) found within the study boundary defined by EPD’s Study Brief. This was firstly prepared by desktop research study on aerial photos and topographical maps, then by site visits and photo-retaking for verification. • Assessment of “Sensitivity to Change” to the LR and LCA. This is affected by factors including: (i) whether the resource is common or rare; (ii) whether it is considered to be of local, regional, national or global importance; (iii) whether there are any statutory or regulatory limitations / requirements relating to the resource; (iv) the quality of the resource; (v) the maturity of the resource, and (vi) the ability of the resource to accommodate changes. The sensitivity of each LR and LCA is separated into construction phase and operation phase. The rating is classified as below: Final 7-3 Hong Kong Convention and Exhibition Centre Atrium Link Extension Environmental Impact Assessment Report High: Important LR or LCA of particularly distinctive characteristics or high importance, and is sensitive to relatively small changes Medium: LR or LCA of moderate landscape characteristics and value, and is reasonably tolerant to change Low: LR or LCA with low landscape characteristics and value, and is largely tolerant to change • Assessment of “Magnitude of Change” for landscape impacts. This is affected by factors including: (i) the physical extent of impact; (ii) the landscape context of impact and (iii) the time-scale of impact, such as whether it is temporary (short, medium or long term), permanent with reversible potentials, or irreversibly permanent. Magnitude of Change is separately considered for construction phase and operation phase. For operation phase, it is further divided into a scenario with all adjacent waterfront developments (i.e., Road P2, WDII etc.) to be constructed and another scenario without these developments. The assessment for these scenarios, however, still refers to the magnitude of change arisen from the operation of the proposed Atrium Link Extension itself with all these developments in the background/ context. The rating for “Magnitude of Change” is classified as below: Large: LR or LCA will suffer a major change. Intermediate: LR or LCA will suffer a moderate change. Small: LR or LCA will suffer a barely perceptible change. Negligible: LR or LCA will suffer no discernible change. • Assessment of the “Impact Significance Threshold Before Mitigation” for landscape impacts. The assessment of landscape impacts during construction, during operation with or without all adjacent waterfront developments is produced by synthesizing the “Sensitivity to Change” and “Magnitude of Change” for various LR and LCA according to Table 7.1 . The degree of significance is divided into four thresholds, depending on the combination: Substantial: Adverse / beneficial impact where the proposal will cause significant deterioration or improvement in existing landscape quality Moderate: Adverse / beneficial
