Sensitivity of Coastal Environments to Spilled Oil: Central California

Research Planning Inc. (May 2006)

Atlas, 41 maps


Environmental Sensitivity Index (ESI) maps have been developed for the coastal areas of Central California from Point Conception to Point Reyes National Seashore. The ESI maps are a compilation of information from three main categories: shoreline types, sensitive biological resources, and human-use resources.

The individual map pages in this atlas are divided according to the U.S. Geological Survey (USGS) 7.5-minute, 1-24,000-scale topographic quadrangle index. Black and white scanned images of these maps are used as a backdrop for each map page in the atlas.
