Abstract

This report documents future coastal erosion hazards and the methodology used to estimate potential erosion, as part of the Coastal Infrastructure and Vulnerability Assessment Project. The study provides estimates of coastal erosion hazards for the California coast from Santa Barbara to the Oregon border. In addition, PWA compiled a statewide base flood elevation layer to support a flood analysis by the Pacific Institute (Pacific Institute 2009). This erosion methodology is applicable to other areas along the west coast of the United States, and was developed to be modular so that updated estimates could be more rapidly accomplished with improved data and refined methods.
