Section 8 Conclusion
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 Island Eastern Corridor Link (Register
No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai
Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and
11 December 2008 respectively.
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 east-west Connaught Road
Central/Harcourt Road / Gloucester Road Corridor (the Corridor) which is
currently operating beyond its capacity. The CWB will provide relief to the
existing congestion along the Corridor and cater for the anticipated growth of
traffic on Hong Kong Island. Without the CWB and its access roads, there will
not be sufficient capacity to serve the heavy traffic demands at both strategic
and local levels.
2.2.1.
Design and
Construction of Central Wan Chai Bypass and Island Eastern Corridor Link
under the Project involves the construction and operation of a trunk road and its
road tunnel more than 800m in length between portals that is shown at Figure 2.1.
2.2.2.
The study area
encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:
-
A dual
three-lane trunk road, approximately 4.5 km in length, and tunnel approximately
3.7 km in length defined from the connection with the existing Rumsey Street
Flyover in Central, through to a connection with the existing Island Eastern
Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);
-
The Central
Interchange near the Rumsey Street Flyover to provide road connections to the
Central area;
-
Tunnel control
buildings and ventilation buildings;
-
Slip roads to
connect the CWB to the local road system in the Wan Chai North and Causeway Bay
area;
-
Associated
road lighting, road signing, traffic control and surveillance system; and
-
Other
associated works.
2.2.3.
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 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.
2.3.2.
In the reporting period, all the contracts were commenced and
contract no. 04/HY/2006 had been completed. The details of individual
contracts are summarized in Table2.2.

monitoring. Immediately prior to and following each noise measurement the
accuracy of the sound level meter shall be checked using an acoustic calibrator
generating a known sound pressure level at a known frequency. Measurements may
be accepted as valid only if the calibration level from before and after the
noise measurement agree to within 1.0 dB.
3.1.8.
Noise measurements shall not be
made in fog, rain, wind with a steady speed exceeding 5 m/s or wind with gusts
exceeding 10 m/s. The wind speed shall be checked with a portable wind speed
meter capable of measuring the wind speed in m/s.
3.1.9.
The sound level meter shall be
checked using an acoustic calibrator generating a known sound pressure level at
a known frequency before deployment to the site and during each site visit.
