Potential Reclamation Extent. LKST and LKT together has an extensive coastal area with shallow seabed level. Reclamation is technically feasible, and the potential reclamation area is approximately 220 to 250 hectare on plan as shown in Figure 4.1. It stretches about 3 km in the north-south direction and 700m to 1 km in the east-west direction between the existing shore and the new reclamation edge. With such a sizeable reclaimed area, there are countless potential for development.
Potential Reclamation Extent. The potential reclamation extent was assessed in consideration of hydrodynamic, existing marine traffic pattern in Urmston Road and the sightings of CWD. It is limited within the embayment of shallow water to avoid changing the hydrodynamic regime within the nearby water bodies, to avoid encroaching upon the key navigation channel and the key CWD habitat just outside the bay. This extent is preliminary only and subject to review when the future land uses on the reclamation area, in particular along the shore, are determined and when detailed studies and investigation including EIA are undertaken. Industrial uses might need marine transportation and loading or unloading of goods at the berths on the waterfront. Straight reclamation edge was initially proposed in the southern portion of the site that could allow marine access and berthing of vessels along the seaward edge. Vertical seawall would be required where berthing facilities are proposed. To provide sufficient space between the existing marine traffic using Urmston Road and the vessels berthing at the reclamation edge, the straight reclamation edge is set back by 100m from the line joining the Black Point headland in the north and the existing berth at the CPPS in the south. Dredging might be required to provide adequate water depth for vessel berthing and manoeuvring along the reclamation edge. An existing effluent outfall, maintained by the Drainage Services Department (DSD), was identified within the potential reclamation area at the northern portion. This outfall connects to the North West New Territories Sewage Tunnel to convey and discharge the treated effluent from San Wai Sewage Treatment Works (STW) at Urmston Road, serving the catchments of Xxxx Xxxx peripheral area, North Tuen Mun and the Xxxx Xxx-Xxxx Long Corridor, Tin Shui Wai and Au Tau/Long Ping. Considering the importance of the existing submarine outfall to its catchments and the significant challenges in re-provisioning of this outfall at the heavily trafficked Urmston Road, the existing outfall should be retained and kept intact. Reclaiming over the outfall is not recommended as this would load the outfall and its surrounding soil that they were not originally designed for. Due to the no-dredging requirement near the outfall, on-shore berthing is not allowed in the northern portion of the reclamation site in the preliminary layout.
