Description: This is digital Seismic Hazard Zone features presenting areas where landslides may occur during a strong earthquake. This feature set was assembled from quadrangle-level feature sets, produced by the California Geological Survey (CGS), by the Metropolitan Transportation Commission. The most recent updates within this feature set were published on April 04, 2019 by CGS.Developers of properties falling within a landslide seismic hazard zone may be required to investigate the potential hazard and mitigate its threat during the local permitting process.This data is used by cities and counties to regulate development and by property owners selling property within areas where seismic hazard zones have been identified. Local governments can withhold development permits until geologic or soils investigations are conducted for specific sites and mitigation measures are incorporated into development plans. Sellers of property use the maps to check the location of their specific site and, if applicable, disclose to the buyer that the property lies within a seismic hazard zone as required by the Seismic Hazards Mapping Act of 1990 (Public Resources Code, Division 2, Chapter 7.8). For information regarding the scope and recommended methods to be used in conducting the required site investigations, see California Geological Survey Special Publication 117A, Guidelines for Evaluating and Mitigating Seismic Hazards in California.More information can be found on the California Geological Survey's Seismic Hazard Zonation Program website: https://www.conservation.ca.gov/cgs/shzp/Pages/shmprealdis.aspx
