Community Exposure in U.S. California to Future Shoreline Change Hazards, reference year 2020

Socioeconomic impact estimates of community exposure to shoreline change hazards are presented for communities along the coast of California, U.S. The provided data were generated using the Hazard Exposure Reporting and Analytics (HERA) web application (www.usgs.gov/apps/hera/). HERA uses geospatial analysis of socioeconomic indicators (population, economic, land cover, and infrastructure) in combination with shoreline change hazard zones developed by the USGS Pacific Coastal and Marine Science Center to quantify populations and assets at risk under present and future scenarios of sea level rise and storm conditions. The type of information includes U.S. Census data on the number and types of residents, InfoGroup data on numbers and types of employees, county parcel values, NLCD land cover estimates, and infrastructure data on roads, rail, and critical facilities from a variety of sources.
