2.2.2.
The
key purpose of the study area encompasses the area of Victoria Harbour to the
southeast of the new Outlying Islands Ferry Piers and north of Edinburgh Place
and Lung Wui Road. The area extends eastward to Fenwick Pier Street and the
Fleet Arcade, and includes the existing GPO, Star Ferry Piers, Queens Pier,
City Hall, PLA Headquarters, Hong Kong Red Cross Headquarters building and the
Tamar Site. The
scope of the Central Reclamation, Phase III includes:
·
Reclamation and seawalls, roads and associated

(ATRT) for the CWB;
·
Reprovisioning of Star Ferry Pier, public landing
steps, wallah wallah moorings, and motor boat/launch operators' kiosks;
·
External cooling water systems which consist of the
cooling water pumping shells for future developments, and the reprovisioning of
existing cooling water pumping stations and associated pipework systems and
E&M works;
·
Reprovisioning of existing Leisure and Cultural
Services Department (LCSD)'s facilities;
·
Provision of a flood relief path, stormwater
culvert extensions, upgrading of hinterland stormwater drainage resulting from
the reclamation, demolition of the existing waterfront structures and necessary
landscaping;
·

4.3.4.
The
interval between two sets of monitoring should not be less than 36 hours except
where there are exceedances of Action and/or Limit Levels, in which case the monitoring
frequency will be increased. Table 4.4 shows the proposed
monitoring frequency and water quality parameters. Duplicate in-situ
measurements and water sampling should be carried out in each sampling event.
For selection of tides for in-situ measurement and water sampling, tidal range
of individual flood and ebb tides should be not less than 0.5m.

7.0.1.
This
section addresses the relevant cumulative construction impact due to the
concurrent activities of the current projects including the Central Reclamation
Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass
(CWB), Island Eastern Corridor Link projects (IECL) and Wan Chai Development
Phase II – Central – Wan Chai Bypass at Wan Chai East (CWB Tunnel).
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. As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting month.
7.0.3.
According
to the construction programme of Central-Wanchai Bypass at Wanchai West at the
Central Reclamation Phase III area, no works was conducted in June 2020
reporting period. In view of the above, the cumulative construction impact due
to the Central Reclamation Phase III (CRIII) was not anticipated.
7.0.4. According to the
construction programme of Wan Chai Development Phase II, Central-Wan Chai
Bypass and Island Eastern Corridor Link projects, no construction works under
Wan Chai Development Phase II was conducted at Wan Chai. The major construction
activities under Central-Wan Chai Bypass and Island Eastern Corridor Link
Projects were ventilation building ABWF works and modification works at
Central; drainage improvement work and utility diversion works at Victoria
Park; bridge noise enclosure installation works, road works, drainage works,
soft landscape works and ventilation building ABWF work at North Point area in
the reporting period. In addition, other non-Wan Chai Development Phase II,
Central-Wan Chai Bypass and Island Eastern Corridor Link projects were observed
undertaken at Wan Chai North and North Point area.
7.0.5.
As
relevant site mitigation measures for air quality and construction noise were
implemented, no significant air quality impact and noise impact from
construction activities was concluded in the reporting period. Besides, no
construction work was conducted at EP-122 area in the reporting period. Thus,
it is evaluated that the cumulative construction impact from the concurrent
projects including Wan Chai Development Phase II (WDII), Central- WanChai
Bypass (CWB), Island Eastern Corridor Link projects (IECL) was insignificant.
