The HKIS & LI Study remarked that given the limited residential development opportunities in other parts of Lamma Island, the residential development potential of the Ex-Lamma Quarry Area at Sok Kwu Wan (Study Site) may be considered on its future land use. 1.2.2 PlanD and CEDD of the Government then commissioned the Planning and Engineering Study on Future Land Use at Ex-Lamma Quarry Area at Sok Kwu Wan, Lamma Island – Feasibility Study in early 2012 to examine the future land use and explore the development potential of the Study Site, as well as the impacts of the proposed developments on the surrounding areas and adjacent water areas. The findings and recommendations of the Project will serve as a reference for the preparation and revision of the relevant town plans to guide the future development of the Study Site, and provide the basis for further engineering investigation and detailed design for the implementation of necessary infrastructure works. An Environmental Impact Assessment (EIA) which is the subject of the revised Project Profile is within the scope of the Project. 1.2.3 The Project comprises tourist and recreational facilities accompanied by housing developments in the Study Site. Supporting infrastructure including refuse transfer facility, sewage treatment works, ferry and refuse transfer piers, submarine sewage outfall, etc. will be provided within the Study Site and the works areas identified in the Study Area. 1.2.4 In the course of the study, requirements for additional works areas to accommodate these supporting infrastructures have been identified beyond the original Study Area. The revised Study Area is shown in Figure 1.1. 1.3 Name of Project Proponent 1.3.1 The Project Proponent is Hong Kong Island and Islands Development Office (HKI&I DevO), Civil Engineering and Development 219753 | Revised Draft | 25 February 2014 G:\ENV\PROJECT\219753-03\12 REPORTS DELIVERABLES\PROJECT PROFILE\20140116 REVISED DRAFT PROJECT PROFILE\REVISED PROJECT PROFILE V5 ENG_FT.DOCX Page 1 Planning Department and Civil Engineering and Agreement No. CE 33/2011 (CE) Planning and Engineering Study on Future Land Use at Ex- Development Department Lamma Quarry Area at Sok Kwu Wan, Lamma Island – Feasibility Study Revised Project Profile Department (CEDD) of the Government of the Hong Kong Special Administrative Region (Government). 1.4 Location and Scale of Project and History of Site 1.4.1 The Study Site is located at the Ex-Lamma Quarry (ELQ) on the northern coast of Sok Kwu Wan. It was established in 1978 for rock extraction and miscellaneous processing and storage use. After years of operation, it was left with steep rock faces that scarred the landscape of the area. 1.4.2 In 1995, the Government endorsed the findings of Rehabilitation of Lamma Quarry Planning and Engineering Study (the Rehabilitation Study) conducted by Geotechnical Engineering Office (GEO) of the Civil Engineering Department, i.e. adopting the recreational land use as the preferred land use option and the Master Landscape Plan so formulated for rehabilitation. Although the option for recreational land use was adopted, it is identified in the Rehabilitation Study that the adoption of the preferred option does not preclude future modification for residential cum recreational uses, of which low density residential development would be kept at the base of the northern slopes and on the northern platforms. 1.4.3 The rehabilitation contract of the Rehabilitation Study for the Study Site was completed in December 2002. The following works were carried out under the contract: a. Formation of a new landform comprising a broad, gently sloping series of platforms bounded to the north with slopes which merge with the natural hillsides. b. Formation of a 5-hectare man-made lake with a natural, non- engineered appearance and gently shelving edges which can support reed bed. c. Landscaping and planting of exotic and native trees to create a self-sustaining, maintenance free, green environment with a similar biodiversity to the surroundings. 1.4.4 In May 2011, the Study Site was put under Short Term Tenancy (STT) to Young Men Christian Association (YMCA) for a non-profit making environmental education and wild life learning centre for a period of 3 years certain and thereafter quarterly. The 5-hectare man- made lake remains in the middle of the Study Site. It connects with some small ponds and discharges into the sea via a spillway at eastern end of the Study Site. At the south western end of the Study Site, there locates a mass concrete pier, which is some 500m to the northwest of Sok Kwu Wan Pier No. 2. The existing geological condition is mainly granite and reclamation. 1.4.5 Currently, the Study Site is covered by the approved Lamma Island OZP No. S/I-LI/9 and is zoned “Undetermined” pending detailed consideration of the appropriate uses. It covers an area of about 34.3 hectares with about 1 km of coastline. 219753 | Revised Draft | 25 February 2014 G:\ENV\PROJECT\219753-03\12 REPORTS DELIVERABLES\PROJECT PROFILE\20140116 REVISED DRAFT PROJECT PROFILE\REVISED PROJECT PROFILE V5 ENG_FT.DOCX Page 2 Planning Department and Civil Engineering and Agreement No. CE 33/2011 (CE) Planning and Engineering Study on Future Land Use at Ex- Development Department Lamma Quarry Area at Sok Kwu Wan, Lamma Island – Feasibility Study Revised Project Profile 1.4.6 In order to take into account the future developments in the Comprehensive Development Area (CDA) site (southwest of the Study Site) and to ensure the natural hazard and ecological values of the adjacent slopes (north of the Study Site) are properly considered, a larger area, the “Study Area” is included for the Study. 1.4.7 The Study Area, with a total area of 59.9 hectares, falls under the approved Lamma Island Outline Zoning Plan No.
