Landslide mapping
Information on current landslide and steep slope mapping, information, and resources.
The potential landslide hazard areas map identifies areas that have been categorized as potential landslide hazard areas. The map does not purport to identify actual landslide hazards or existing landslide risks for specific properties. Depending on the nature of any proposed development, further investigation of the site and a detailed evaluation of the landslide hazard by a licensed geological engineer may be recommended.
