Section 10        Conclusion

2.         Project Background

2.1               Background

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               Scope of the Project and Site Description

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 June 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.

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 June be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.

4.1.8.        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.

4.1.9.        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. Measurements June be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.

7.0.1.        According to Condition 3.4 of the EP-364/2009/A, 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.        From the Monthly EM&A report (June 2011) of Central Reclamation Phase III the key works in June 2011 are as follows:

·          Type A filling in FRAW and FRAE above +2.5mPD

·          General filling works above +2.5mPD in IRAE

·          Surcharging in FRAW and FRAE

·          Construction of cantilever slab at caisson

·          Construction of storm and foul drainage and gullies in hinterlands for Road P2 and Road D9

·          Construction of GPO boundary wall

·          Construction of PLA boundary wall and entrance

·          Construction of Promenade enhancement works

·          Construction of buildings at PLA berth

·          Road P2 Underpass ramp structures

·          Precasting for retaining wall (offsite)

·          Installation of cooling mains discharge pipes in FRAE and FRAW

·          Construction of CWB structure

·          Backfilling of CWB structure

·          Importation of fill material

·          Strengthening of Man Yiu Street Footbridge

 

7.0.3.        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 was the filling at Temporary Causeway Bay Reclamation 1 East (TCPR1E) and Temporary Public Cargo Working Area Reclamation (TPCWA), dredging works at Temporary Causeway Bay Reclamation 1 West (TCPR1W), dredging and filling works at Wan Chai Reclamation Stage 1(WCR1), Advanced piling works at FEHD Whitfield Depot, Central Interchange, cross-harbour water mains and marine pre-drilling in the reporting month. The major environmental impact was water quality impact at Causeway Bay and Wan Chai. Land-based construction activity was only advance piling works at FEHD Whitfield Depot, sheet piling and pre-drilling works at Central, marine pre-drilling at North Point in the reporting month and tunnel works at Wan Chai East.

7.0.4.        The major environmental impacts generated from the Central Reclamation Phase III were located along the coastline of Central and Admiralty while advanced piling works at FEHD Whitfield Depot were undertaken and sheet piling, pre-drilling works at Central and tunnel works at Wan Chai East in the reporting month. No significant air, noise impact were anticipated in the reporting month. Besides, no environmental monitoring exceedance was recorded from the Project in the reporting month.  Thus, it is evaluated that the cumulative construction impact from the concurrent projects including Wan Chai Development Phase II and Central Reclamation Phase III was insignificant.
