Floods are the most common and destructive natural disaster in the United States. The National Flood Insurance Program (NFIP), which collected about $3.8 billion in premiums and insured about $1.3 trillion in property in 2013, is administered by the Federal Emergency Management Agency (FEMA). The program is a key component of the federal government's efforts to limit the damage and financial impact of floods. NFIP makes federally backed flood insurance available to property owners in participating communities. Additionally, through NFIP, FEMA maps floodplain boundaries, and requires participating communities to adopt and enforce floodplain management regulations that mitigate the effects of flooding.
