Community Exposure in U.S. Guam to Future Coastal Flooding Hazards, reference year 2020

Socioeconomic impact estimates of community exposure to coastal flooding hazards are presented for communities along the coast of U.S. Guam. 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 flood 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 of residents, county parcel values, C-CAP land cover estimates, and infrastructure data on roads and critical facilities from a variety of sources.
