Design and construct 220 m long drainage channels along the CKWLR to mimic natural streams to compensate for the unavoidable loss of stream courses due to the CKWLR construction.  The created stream courses should have natural substrate so as to provide suitable habitats for the colonization of stream invertebrates.  The stream habitats will be restored partly by natural silting due to flow from upper stream.  Selected substratum should resemble the existing stream conditions and large granite boulders may be placed at the upstream section so that these boulders will be weathered naturally to smaller pebbles and fine particles, forming natural stream substrate.

Detailed design on structural support for the CKWLR at the original coastal areas at Cheoy Lee Shipyard (CLS) site should be avoided and kept the potential impact to an absolute minimum. . An opportunity shall be provided for an archaeological field evaluation at the coastal area of existing CLS after its resumption, as part of the Schedule 2 EIA for the Shipyard decommissioning.  If preservation in situ is not possible for the archaeological deposit identified under the CLS decommissioning EIA, the impacted archaeological deposits should be mitigated by rescue excavation.   However, as the Penny’s Bay reclamation would result in limitation for future archaeological investigation at the area.  A total rescue excavation instead of a partial rescue excavation could be considered to preserve the site by record in totality.

As the Chok Ko Wan archaeological may potentially filled up due to the Penny’s Bay reclamation and the site may potentially impacted by the structural support and construction work of the CKWLR, having considered that this site has been investigated a number of times and partially destroyed by the construction of the CLP power station, only partially preservation in situ is possible.  It is, therefore, recommended that a full rescue programme be implemented prior to the reclamation of this site to allow preservation by record in totality.
