Landslip Warning Signs

For slopes and retaining walls which have been identified to be substandard or to pose a landslide risk, appropriate warning signs will be erected. Four types of warning signs are used:

sign of Man-made Slope

Man-made Slope

This sign signifies a man-made slope which has been included in the Landslip Prevention and Mitigation (LPMit) Programme works contract, or a man-made slope for which a statutory order (i.e. Dangerous Hillside Order) has been issued by the Building Authority, requiring investigation and/or remedial works.

sign of Natural Terrain

Natural Terrain

This sign signifies a slope in natural terrain which has been included in the LPMit Programme works contract, or an area in close proximity to completed natural terrain mitigation measures.

standard traffic warning sign 487

Slopes Along Busy Roads with a History of Landslides

This standard traffic warning sign 487 is erected along busy roads with a history of landslides.

sign serves to warn the affected squatters

Slopes Affecting Squatters included in the Non-development Clearance (NDC) Programme

This sign serves to warn the affected squatters about potential landslide risk before rehousing. The affected squatter structures have been found to be especially vulnerable to landslide risk during rainfall, and GEO has recommended to the Lands Department to include the squatter structures in the NDC programme.
