Adobe Reader®  is required to view the landslide maps or geologic report.                                   

getacro.gif (712 bytes)Maps are provided in PDF format.  A large format plotter (minimum 36" width) is required to print these maps at full scale.

GIS data are provided as zipped folders of ESRI coverages and shapefiles in both Teale Albers (NAD27) and UTM Zone 10 (NAD 83) projections. 

A complete list of landslide maps and geologic maps by the California Geological Survey is available.

DISCLAIMER:

The State of California and the Department of Conservation make no representations or warrantees regarding the accuracy of the data from which these maps were derived. Neither the State nor the Department shall be liable under any circumstances for any direct, indirect, special, incidental or consequential damages with respect to any claim by any user or any third party on account of or arising from the use of these maps.

The identification and location of landslide hazard areas are based on review of limited aerial photographs that are listed on each specific map. In most cases, only two sets of aerial photographs were used to construct the landslide and geomorphic features maps. Due to time constraints all available data were not necessarily reviewed and used in construction of these maps. The quality of data used is varied. The information depicted on the maps has been drawn as accurately as possible at 1:24,000 scale. The maps and reports provided on this web site are subject to change without notice, and the latest available versions will be posted on this web site.

Information on the maps are not sufficient to serve as a substitute for site specific geologic and geotechnical site investigations as required under the Chapters 7.5 and 7.8 of Division 2 of the Public Resources Code.
