The project is for the development of the Reserve Zone (RZ) and Area 3, 30 & 31 of the Development Zone (DZ) in Tin Shui Wai for public and private housing development. The project area for the proposed development of Areas 3, 30 & 31 of the DZ and the RZ comprises mainly of newly reclaimed land now covered by grasses. Some areas left undeveloped since the works in the early 1990s have become temporary habitats for the feeding and breeding of some species. More valuable habitats are mainly found at the northern periphery of the reclaimed Reserve Zone. These include woodlands, mangroves, intertidal mud flats and other wetlands. The most important one is the mud flat at Inner Deep Bay which was listed as a Ramsar Site in 1995.

Under the EIA, a 12-month ecological study was conducted in December 1995. The study found that the major ecological impacts of the Project are the loss of habitats, potential deterioration of water quality and disturbance from human activities. Various measures are proposed in the study to mitigate against the impacts. One of the major mitigation measures is the formation of a 18.5 ha "constructed wetland" as replacement habitat for the wetland lost from the project and to act as a buffer area between development and the Inner Deep Bay . The "constructed wetland" will also receive storm water runoff collected from the Eastern Culvert and will remove pollutants through sedimentation and wetland mechanisms before the water enters Inner Deep Bay. The study concludes that the mitigation measures to be implemented will safeguard water quality and prevent the mudflats at Inner Deep Bay from being adversely affected. The proposed "constructed wetland" and the adjacent woodland will form a buffer to minimise human disturbance on the Ramsar site. |

Title of Designated Project |
Tin Shui Wai Development Engineering Investigations for Development of Areas 3, 30 & 31 of the Development Zone and the Reserve Zone
|
Nature of Designated Project |
- improvement to existing roads;
- railway and its associated stations;
- drainage channel;
- a residential or recreational development, other than New Territories exempted houses, within Deep Bay Buffer Zone 1 or 2
Note: This project is exempted under EIA Ordinance since this EIA report was approved prior to implementation of EIA Ordinance |
Location of Designated Project |
Tin Shui Wai |
Scale and Scope of Designated Project(s) |
The major infrastructure of this Project includes:
- about 6km of new roads in the RZ;
- widening of about 5.5km of existing roads which includes:
ο Tin Wah Road which divides the RZ from the DZ;
ο Tin Ying Road and the northern part of Hung Tin Road which form the main western access;
ο Tin Tsz Road and the northern part of Long Tin Road which form the main eastern access;
ο improvements for the junctions along these roads including six new road-bridges;
- junction improvement works including additional turning lanes and pedestrian facilities;
- three new bridges across the Western Drainage Channel Extension bordering the RZ, six new cycle and pedestrian foot bridges; six pedestrian subways, about 14km of footpath and 8km of cycle track;
- a new sewage pumping station in Area 101 and about 1.5km of rising mains along the Western Drainage Channel connecting the station to the existing sewage pumping station at Ha Tsuen;
- about 4.5km of new trunk gravity sewers;
- about 2km of new main stormwater drainage culverts including the culverting of about 0.5km of the Eastern Temporary Channel;
- concrete lining to a 0.5km section of the Western Drainage Channel Extension immediately downstream of the existing inflatable dam;
- landscaping of all road reserves; and
- formation of about 5km long light Rail Transit reserve to be developed by Kowloon Canton Railway Corporation.
