Customer Tip:

Are you prepared for flooding?

When rain storms are intense, the city’s storm drain system can become overwhelmed and flooding can occur. It’s a good idea to get prepared now and know what to do to protect your property and yourself.

Properties located within floodplains or next to streams, lakes and wetlands are most susceptible to flooding. Floodplains benefit the entire community by providing temporary storage of floodwaters until a storm subsides.

Bellevue’s drainage system also includes flood detention ponds, pipes and ditches. Some parking lots and parks are even designed to fill with water during big storms.

Floodplain boundary lines are shown on FEMA flood insurance rate maps. To find out if your property is located within a floodplain, call Utilities at 425-452-5206 or check Bellevue’s floodplain maps.

The city also keeps elevation certificates on file for permitted construction within the floodplains. Flood insurance is required for structures in the floodplain that also have federally-backed mortgages. Flood insurance can be purchased through the National Flood Insurance Program, which provides flood insurance for all properties. Even if you don’t live in a floodplain, flood insurance is recommended. 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 a leaking sink.

Ask your insurance carrier for information about the National Flood Insurance Program (NFIP). Bellevue residents receive a 25 percent discount on NFIP policies due to Bellevue’s floodplain management program. There is a 30-day waiting period before the policy goes into effect.
