The Civil Engineering & Development Department has been conducting major mitigation measures to reduce the landslide risk at slopes.
Its Geotechnical Engineering Office, which looks after slope safety in Hong Kong, has been carrying out mitigation works on the natural hillside above Yu Tung Road in North Lantau since 2009.
Four reinforced concrete barriers to retain debris and a row of steel mesh fences to sustain landslides were installed using a green design to enhance the works’ aesthetics.
During a press briefing on pre-wet season slope safety today, Geotechnical Engineering Office Deputy Head Au Yeung Yan-sang said severe rainstorms in June 2008 triggered a number of landslides on the hillside and Yu Tung Road had to be closed for two months.
Mr Au Yeung noted that the Hong Kong Observatory has predicted a higher than average rainfall this year, which increases the risk of landslides.
The department will implement the necessary risk mitigation works for at least 30 natural hillside catchments and 150 Government man-made slopes to ensure public safety, he added.
