Geologic hazards pose a risk to public health and private property and to the natural systems that make up the county's environment. These lands are susceptible to landslides, erosion, seismic, volcanic and mining hazards. Building and development practices should consider topographical and geological features. Future development should be directed to more geologically stable areas and restricted on unsuitable ground. Regulating these lands, and avoiding or minimizing alteration of geologic hazards, is necessary to protect the health, safety and general welfare.
