11.1.1 A desktop review of relevant available marine archaeological information and relevant geophysical data within the project area of the Cross-habour water mains from Wan Chai to Tsim Sha Tsui was conducted by a qualified marine archaeologist. The results of the review are presented below.

Review
of Report NO: SDA8827
11.2.1 In May 2001 the AMO commissioned SDA Marine Ltd to undertake a MAI for Wanchai Reclamation Phase II. In accordance with AMO Guidelines the MAI comprised: Baseline Review, Geophysical Survey and Underwater Inspection.
11.2.2
The study area exactly
replicated the current study area with the exception of a small section at
North Point adjacent to the
11.2.3
The Baseline Review indicated a
high marine archaeological potential as the study area has always been at the
centre of development and industry within
11.2.4 The geophysical survey deployed: echo sounder, seismic profiler and side scan sonar. The survey was commissioned to meet the needs of the MAI and therefore the methodology was designed to enhance acquisition of archaeological data.
11.2.5 The survey provided 200% coverage of the seabed and subsurface sediments. Nine anomalies were identified in the survey data. A diver inspection was carried out to obtain accurate information about their archaeological potential. Each anomaly was successfully located and examined by a diver. There were two modern shipwrecks, four pieces of metal construction material, two large concrete blocks and a small metal container.
11.2.6 It was concluded that there were no archaeological resources within the study area and no need for any mitigation measures or constraints on the proposed development.
11.3
Mitigation of Adverse Impacts
11.3.1 Since there is no archaeological material present within the project area, there is no need for any further archaeological investigation or mitigation measures.
11.4
Residual
Environmental Impact
11.4.1 No residual cultural heritage impact is expected.
11.5
Environmental
Monitoring and Audit Requirements
11.5.1 There is no monitoring and audit requirement for the marine archaeology.
11.6.1
The
results of the MAI in 2001 (Report No. SDA8827) are applicable to the current
study since they cover the same seabed area. There have not been any significant changes
to the seabed since 2001 which would have affected its archaeological
potential. According to the MAI in 2001, it was concluded there were no
archaeological resources within the project area of the Cross-harbour water
mains.
