Geologic Hazards (Subsidence, Landslides) 7.01
Coordinate with Irvine Ranch Water District and the Navy on subsidence monitoring in areas of active groundwater extraction and work with water utilities to develop strategies based on the amount and severity of subsidence occurring. Consider reducing land use densities in areas of significant landslide threat and identify strategies for existing development downstream of these hazard areas. Discourage new sensitive land uses, including schools, parks, childcare centers, adult and senior assisted living facilities, and community centers, from locating near identified hazardous material facilities. Discourage or prohibit new hazardous material facilities from locating near sensitive land uses.
