2.1.1.
¡§Wan Chai Development phase II and Central-Wan Chai
Bypass¡¨ and ¡§Central-Wan Chai Bypass and Island Eastern Corridor Link¡¨
(hereafter called ¡§the Project¡¨) are Designed Project (DP) under the
Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). The Environmental
Impact Assessment (EIA) Reports for Central-Wan Chai Bypass and
2.1.2.
The key purpose of Wan Chai Development Phase II
(WDII) is to provide land at Wan Chai North and North Point for construction of
the Central-Wan Chai Bypass and Island Eastern Corridor Link (CWB). Land formed
under the project will be developed as a world-class waterfront promenade
joining that at the new Central waterfront for public enjoyment.
2.1.3.
There is a compelling and present need for the CWB
to provide relief to the very congested
2.2.1.
The Project is located mainly in Wan Chai North,
2.2.2.
The study area encompasses existing developments
along the Wan Chai,
2.2.3.
The scope of the Project
comprises:
¡P
Land formation
for key transport infrastructure and facilities, including the Trunk Road (i.e. CWB) and the associated
slip roads for connection to the Trunk Road and for through traffic from Central to
Wan Chai and Causeway Bay. The land formed for the above transport infrastructure
will provide opportunities for the development of an attractive waterfront
promenade for the enjoyment of the public
¡P
Reprovisioning /
protection of the existing facilities and structures affected by the land
formation works mentioned above
¡P
Extension, modification,
reprovisioning or protection of existing storm water drainage outfalls,
sewerage outfalls and watermains affected by the revised land use and land
formation works mentioned above
¡P
Upgrading of
hinterland storm water drainage system and sewerage system, which would be
rendered insufficient by the land formation works mentioned above
¡P
Provision of the
ground level roads, flyovers, footbridges, necessary transport facilities and
the associated utility services
¡P
Construction of
the new waterfront promenade, landscape works and the associated utility
services
¡P
The Trunk Road
(i.e. CWB) within the study area and the associated slip roads for connection
to the Trunk Road.
2.2.4.
The project also contains various Schedule 2 DPs
that, under the EIAO, require Environmental Permits (EPs) to be granted by the
DEP before they may be either constructed or operated. Table 2.1
summarises the five individual DPs under this Project. Figure 2.1 shows the
locations of these Schedule 2 DPs.

Due to the multi-contract nature of the Project,
there are a number of contracts sub-dividing the whole works area into
different work areas to be commenced. Contractors of individual contracts will
be required by the EP holder to apply Further Environmental Permits (FEP) such
that the impact monitoring stations are sub-divided accordingly to facilitate
the implementation of EM&A programme and to streamline the EM&A
reporting for individual FEP holders correspondingly.
