Roughly 25% of U.S. critical infrastructure is at risk of flooding
A new report highlighting the flood risk over a 30 year period for every city and county across the conterminous United States has been released by First Street Foundation, a science and technology nonprofit organization.
The nationwide, community-level flood resilience report, titled “The 3rd National Risk Assessment: Infrastructure on the Brink,” calculates the risk of five key dimensions of community risk: residential properties, roads, commercial properties, critical infrastructure and social infrastructure. Using the operational flood threshold for each building or piece of infrastructure, the Foundation was able to calculate each dimension’s specific risk of failure and aggregate those findings for every U.S. neighborhood, zip code, city and county.
