Slope safety
1. | (a)
How do I know if my slope is up to the required safety standard? (b) How do I know whether a slope is safe? |

(a)The owner should arrange for a Stability
Assessment to be carried out by a professionally qualified
geotechnical engineer. A Stability Assessment should also
be carried out if significant modifications have occurred
to the slope or retaining wall or to the adjacent area, or
if significant deterioration of the slope or retaining wall
has occurred. |

6. |
Are the private lot owners responsible for the slopes outside but adjacent to their lot boundary? |
|
Private lot owners should examine their relevant lease documents to find out whether they are responsible for the slopes outside but adjacent to their lot boundary and to ascertain the extent of the land they are required to maintain. Where appropriate, professional advice may need to be sought from lawyers or estate surveyors on the interpretation of the lease documents in respect of maintenance responsibility. The public can also access the Slope Maintenance Responsibility Information System (SMRIS) through the Internet web site (http://www.slope.landsd.gov.hk/smris/) to check the maintenance responsibility of slopes. It should be noted that the SMRIS only provides preliminary information on maintenance responsibility of slopes. |
