It is the purpose of these regulations to regulate development in natural hazard areas, including geologic hazard areas, wildfire hazard areas, and floodplain hazard areas, so as to minimize significant hazards to public health and safety, and to:

   A. Geologic Hazard Areas.

   1. Minimize significant hazards to public health and safety or to property in a designated geologic hazard area;

   2. Promote safe use of geologic hazard areas;

   3. Reduce the impact of geologic hazards on life and property by:

   a. Prohibiting certain land uses which are dangerous to life or property in geologic hazard areas,

   b. Restricting the land uses which would be hazardous to the public health and safety or to property in geologic hazard areas,

   c. Restricting the land uses which are particularly vulnerable to geologic hazards so as to alleviate hardship and reduce the demands for public expenditures for relief and protection,

   d. Requiring land uses permitted in geologic hazard areas, including public facilities which serve such uses, to be protected from geologic hazards by providing for geologic hazard investigation and the avoidance of or mitigation of such hazard impacts at the time of initial construction;

   4. Protect geologic hazard area occupants or users from the impacts of geologic hazards which may be caused by their own, or other, land use and which is or may be undertaken without full realization of the danger by:

   a. Regulating the area in which, or the manner in which, structures designed for human occupancy may be constructed so as to prevent danger to human life or property within each structure,

   b. Designating, delineating and describing areas that could be adversely affected by geologic hazards so as to protect individuals from purchasing or improperly utilizing lands for purposes which are not suitable;

   5. Protect the public from the burden of excessive financial expenditures from the impacts of geologic hazards and relief by:

   a. Regulating land uses within geologic hazard areas so as to produce the pattern of development or a soundly-engineered manner of construction which will minimize the intensity and/or probability of damage to property and loss of life or injury to the inhabitants or users of geologic hazard areas,

   b. Regulating the cutting, filling or drainage changes and other man-made changes which could initiate or intensify adverse conditions within geologic hazard areas,

   c. Encouraging such uses as agriculture, grazing, greenbelt, open space, and recreation within geologic hazard areas.

   B. Wildfire Hazard Areas.

   1. To facilitate the administration of wildfire hazard areas by establishing requirements which must be met before development in such areas as permitted;

   2. Establish requirements which are designed to minimize significant hazards to public health and safety or to property in wildfire hazard areas in which human activity is to take place;

   3. Require that authorized developments have adequate roads for service by fire trucks, fire-fighting personnel, and other safety equipment and that fuel breaks and other means of reducing conditions conducive to fire be provided;

   4. Promote proper land use within wildfire hazard areas;

   5. Protect the public against the costs which may be incurred when unsuitable development occurs in wildfire hazard areas;

   6. Preserve and maintain forestry and other natural resources;

   7. Conserve natural conditions of air, water, land, vegetation, wildlife and open spaces for the education, recreation, and general welfare of the public.

   C. Floodplain Hazard Areas. It is the purpose of these regulations to regulate development in flood hazard areas so as to minimize significant hazards to public health and safety; and to operate in coordination with the National Flood Insurance Program; and to prevent substantial solid debris from being carried down stream by flood waters.

   D. Mineral Resource Areas. It is the purpose of these regulations to regulate development in mineral resource areas so as to minimize significant hazards to public health and safety, and to insure the availability to the public of necessary and useful minerals.
