1. Background

1.1 The objective of the Project “Landslide Preventive Works at Po Shan, Mid-levels – Design and Construction (Natural Terrain Risk Mitigation Works)” under Contract CE 28/2004 (GE) is to carry out detailed design and supervision of landslide preventive works on local repair of the hillside to minimize slope deterioration and shallow instability.

1.2 The Project site is located at the mostly undeveloped hillside above the residential development at Po Shan Road and adjacent to the trimmed back slope on the site of the catastrophic 1972 Po Shan Road failure. Previous studies had been carried out and results indicated that the natural hillside above Po Shan Road is affected by high groundwater level and unfavourable geology. Sub-surface drainage measures by means of sub-horizontal drains had been installed in 1984-85. These measures have been successful in lowering the main ground water table, thus improving the stability of the slopes such that large-scale failure has not occurred in the last twenty years. The proposed landslide preventive works would be constructed to protect the existing residential developments at the toe of the project site.

1.3 The scope of works of this Project includes the installation about 700 numbers of soil nails and about 60 numbers of raking drains on the natural terrain within the concerned area. The length of the soil nails is about 20m with a spacing of 2m horizontally and 3m vertically; the length of raking drains is about 10m with a spacing of 5m horizontally and 15m vertically.

1.4 AECOM Asia Company Ltd., integrating the operation of ENSR Asia (HK) Ltd. as of 1 May 2009, was employed by the Contractor, China State – China Railway Joint Venture, as the Environmental Team (ET) to undertake the Environmental Monitoring and Audit (EM&A) works for the Project.

1.5 The construction of the Project and the EM&A programme commenced on 1 April 2008. The construction works, including compensatory planting of vegetations, had been completed in December 2009 and the construction phase EM&A programme was terminated on 31 December 2009, as approval by EPD. The operation phase EM&A programme commenced on 1 January 2010.

1.6 This report documented the findings of Landscape & Visual Audit and Monitoring works conducted in the operation phase period between 1 and 31 January 2010.

2. LANDSCAPE AND VISUAL

Monitoring Requirement

2.1 During the operation phase of the Project, landscape and visual monitoring should be carried out monthly by a Registered Landscape Architect (RLA) to ensure the compensatory planting and horticultural maintenance operations are properly established during the 12 month establishment period. A detailed report is annexed in Appendix A.
