stipulated in the EM&A Manual of the approved Environmental Impact
Assessment (EIA) Report for Wan Chai Development phase II and Central-Wan Chai
Bypass (Register No.: AEIAR-125/2008) and in the EM&A Manual of the
approved EIA Report for Central-Wan Chai Bypass and Island Eastern Corridor
Link (Register No. AEIAR-014/2001).

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.
The
Project is located mainly in Wan Chai North, Causeway Bay and North Point, and
is demarcated by Gloucester Road and Victoria Park Road to the south, Fenwick
Pier Street to the west and Tong Shui Road Interchange to the east, as shown in
Figure 2.1.
2.2.2.
The
study area encompasses existing developments along the Wan Chai, Causeway Bay
and North Point shorelines. Major land uses include the Hong Kong Convention
& Exhibition Centre (HKCEC) Extension, the Wan Chai Ferry Pier, the ex-Wan
Chai Public Cargo Working Area (ex-PCWA), the Royal Hong Kong Yacht Club
(RHKYC), the Police Officers' Club, the Causeway Bay Typhoon Shelter (CBTS) and
commercial and residential developments.
2.2.3.
The scope of the Project comprises:
·
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
·
Reprovisioning / protection of the existing
facilities and structures affected by the land formation works mentioned above
·
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
·
Upgrading of hinterland storm water drainage system
and sewerage system, which would be rendered insufficient by the land formation
works mentioned above
·
Provision of the ground level roads, flyovers,
footbridges, necessary transport facilities and the associated utility services
·
Construction of the new waterfront promenade,
landscape works and the associated utility services
·
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, the status of permits
and/or licences under the individual contract(s) are presented as below:
Contract no. HK/2010/06 – Wan Chai
Development Phase II – Central – Wan Chai Bypass over MTR Tsuen Wan Line under
FEP-05/356/2009
2.3.2
The construction works were completed and the FEP-05/356/2009 was

2.3.1.
The
construction works were completed and the FEP-01/356/2009 was surrendered by
the Contractor on 22 October 2012.
2.3.2.
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.

7.0.1. According
to Condition 3.4 of the EP-356/2009, this section addresses the relevant
cumulative construction impact due to the concurrent activities of the current
projects including the Central Reclamation Phase III, Central-Wanchai Bypass
and Island Eastern Corridor Link projects.
7.0.2. According
to the Final EM&A Report of Central Reclamation Phase III (CRIII) for
Contract HK 12/02, the major construction activities were completed by end of
January 2014 and no construction activities were undertaken thereafter and the
water quality monitoring was completed in October 2011 and no Project-related exceedance
was recorded for air and noise monitoring.
It can be concluded that cumulative construction impact due to the
concurrent activities of the current projects with the Central Reclamation
Phase III (CRIII) was insignificant.
7.0.3.
According to the construction programme of
Central-Wanchai Bypass at Wanchai West at the Central Reclamation Phase III
area, Diaphragm wall construction and pipe pile wall construction were
performed in August 2014 reporting month. As no project related exceedance were
recorded during the reporting period, cumulative construction impact due to the
concurrent activities of the current projects with the Central Reclamation
Phase III (CRIII) was considered as insignificant.
7.0.4.
According to the construction programme of
Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern
Corridor Link projects, the major construction activity under Wan Chai
Development Phase II were marine works at HKCEC areas, tunnel works

construction activities under Central-Wan Chai Bypass and Island Eastern
Corridor Link Projects were bridge construction and tunnel works at Central
Interchange, land base bored pilling works at Victoria Park Road and ELS, segment
launching works and tunnel works at North Point area. The major environmental impact
was water quality impact at Causeway Bay and Wan Chai. Marine-based
construction activities were filling works at WanChai West and removal of
temporary reclamation at TS4, TS2 and EX-PCWA at Wan Chai East in the reporting
month.
7.0.5.
No significant air impact from construction
activities was anticipated in the reporting month. Besides, project related
exceedances recorded during the air and noise environmental monitoring events
in the reporting period were rectified. Thus, it is evaluated that the cumulative
construction impact from the concurrent projects including Central Reclamation
Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass
(CWB), Island Eastern Corridor Link projects (IECL) was insignificant.
