- If your home is in a floodplain, you need flood insurance. Even if you don't live in a floodplain, flood insurance is a good idea because a typical homeowner's insurance policy will not cover water damage unless the damage is caused by interior flooding, such as an overflowing toilet or leaking sink.
- Flood insurance can be purchased through the National Flood Insurance Program (NFIP), which provides flood insurance for all properties. Visit NFIP Floodsmart for more information on floods and flood insurance.
- Bellevue residents receive a 25% discount on NFIP policies due to Bellevue’s floodplain management program. (There is a 30-day waiting period before the policy goes into effect.)
