This national analysis identifies the number of US homes at risk from chronic flooding over the coming decades due to sea level rise. It also shows the current property value, estimated population, and portion of the property tax base at risk. Information is available by state, community, and zip code.
Along nearly 13,000 miles of coastline of the contiguous United States, hundreds of thousands of buildings lie in the path of rising seas: schools, hospitals, churches, factories, homes, and businesses. As sea levels rise, persistent high-tide flooding of homes, yards, roads, and business districts will begin to render properties effectively unlivable, and neighborhoods—even whole communities— nancially unattractive and potentially unviable.
Yet property values in most coastal real estate markets do not currently reflect this risk. And most homeowners, communities, and investors are not aware of the nancial losses they may soon face.
This analysis estimates the number of homes and commercial properties throughout the coastal United States that will be put at risk from chronic, disruptive flooding—defined as flooding that occurs 26 times per year or more (Dahl et al. 2017; Spanger-Siegfried et al. 2017)—in the coming decades.
The goal of the Available Science Assessment Process (ASAP) is to synthesize and evaluate the body of scientific knowledge on specific, on-the-ground climate adaptation actions to determine the conditions, timeframes, and geographic areas where particular actions may be most effective for resource managers. This project identified sea level rise-related adaptation actions applied by resource managers, and evaluated the science behind those actions that may inform - if not improve - coastal planning and management in the Northwest.
This report summarizes the work of two NOAA-funded graduate fellows research on community-level coastal flood management and climate change adaptation best practices throughout the North Atlantic region (Virginia to Maine). Guided by a steering committee composed of government and academic personnel involved with climate adaptation throughout the North Atlantic, the fellows visited coastal communities to collect information on low-cost climate change and related coastal hazard management best practices. The purpose of the work was to identify and collate cost-effective adaptation projects implemented at the municipal level, to provide NOAA with best practice information to assist with ongoing adaptation outreach.
The Story After the Storm series examines the aftermath of Duluth's 2012 flood. The increased frequency of extreme weather, not only in Duluth but across the U.S., has given urgency to understanding community resiliency and regional climate change. The series is part of The Science Institute for Educators, sponsored by the Great Lakes Aquarium, Minnesota DNR MinnAqua Program, Minnesota Sea Grant, and The Wolf Ridge Environmental Learning Center. It is funded in part by the Coastal Zone Management Act, by NOAA's Office of Ocean and Coastal Resource Management, in conjuction with Minnesota's Lake Superior Coastal Program.
