National Flood Insurance Program
Your local community participates in the National Flood Insurance Program (NFIP), which is managed by the Federal Emergency Management Agency (FEMA). The NFIP offers flood insurance to homeowners, renters, and business owners if their community participates in the NFIP. In turn, participating communities agree to adopt and enforce ordinances that meet or exceed FEMA requirements to reduce the risk of flooding.
The NFIP requires levees be ‘accredited’ for them to be recognized as providing flood protection to low-lying areas. Accredited levees have proven that they are designed and have been maintained to protect against the 1% annual chance flood (Note: Levees can never provide absolute flood protection due to residual risk). Living or working behind an accredited levee allows property owners to obtain optional, subsidized flood insurance and removes typical development restrictions usually required for low-lying areas. Alternatively, structures behind a non-accredited levee are subject to mandatory flood insurance policies and rigorous development restrictions to reduce flooding risk.
All 4 levee systems in the Columbia Corridor are currently accredited but will need to be re-accredited in the near future.
