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.
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
·
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.

The construction noise level shall be measured in terms of
the A-weighted equivalent continuous sound pressure level (Leq). Leq (30
minutes) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. For
all other time periods, Leq (5 minutes) shall be employed for
comparison with the Noise Control Ordinance (NCO) criteria.
Supplementary information for data auditing, statistical results such as L10
and L90 shall also be obtained for reference.
3.1.4.
Noise
monitoring shall be carried out at all the designated monitoring stations. The
monitoring frequency shall depend on the scale of the construction activities.
The following is an initial guide on the regular monitoring frequency for each
station on a weekly basis when noise generating activities are underway:
·
One set of
measurements between 0700 and 1900 hours on normal weekdays.
3.1.5.

used for carrying out the noise 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. Measurements may be accepted as valid only if the
calibration level from before and after the noise measurement agree to within
1.0 dB.
