Protecting development in hazardous areas

The presence of steep slopes, creeks, ravines, floodplains and forested lands — combined with occasional extreme weather activity — make some areas of the District susceptible to natural hazards including landslide, debris flow, flood and wildfire.

Our objective is to reduce and mitigate the risk associated with natural hazards.

Development in areas prone to natural hazards requires special consideration due to concerns for personal safety and risk of property damage as well as potential impacts to natural environments.

We have developed a series Development Permit Areas (DPAs) where special requirements and guidelines for any development or alteration of the land are in effect.
