§ 23.07.080. Geologic Study Area (GSA).

A Geologic Study Area combining designation is applied by the Official Maps (Part III) of the Land Use Element, to areas where geologic and soil conditions could present new developments and their users with potential hazards to life and property. These standards are applied where the following conditions exist:

a.

Seismic hazard: Areas of seismic (earthquake) hazard are identified through the application of an Earthquake Fault Zone. Earthquake Fault Zones are established by the state geologist as required by Sections 2621 et seq. of the Public Resources Code (the Alquist-Priolo Earthquake Fault Zones Act), and are identified in the Land Use Element (Part II);

b.

Landslide hazard: Areas within urban and village reserve lines, identified by the Seismic Safety Element as being subject to moderately high to high landslide risk, and rural areas subject to high landslide risk;

c.

Liquefaction hazard: Areas identified by the Seismic Safety Element as being subject to soil liquefaction.

d.

Erosion and stability hazard - coastal bluffs. Areas along the coast with coastal bluffs and cliffs greater than 10 feet in vertical relief that are identified in the Coastal Erosion Atlas, prepared by the California State Department of Navigation and Ocean Development (1977), in accordance with Hazards Policy No. 7 of the Local Coastal Plan.
