Levee Accreditation

Visit www.leveereadycolumbia.org to learn more about how the drainage districts are partnering with our partners to reduce the risk of flooding for the Portland International Airport, tens of thousands of jobs and residences, thousands of acres of local farmland, and hundreds of acres of parks and natural areas.

National Flood Insurance Program

Your local community participates in the National Flood Insurance Program (NFIP),National Flood Insurance Program logo 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 deveMarine Drive Leveelopment 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.
