How often does St. Clair County flood?

Does homeowners insurance cover flooding?

No. Standard homeowners and renters insurance policies exclude flood damage. You need a separate flood policy from the NFIP or a private insurer.

How long until a new flood policy starts?

NFIP policies usually have a 30-day waiting period, so buying when a storm is already forecast is normally too late. Exceptions apply, for example when a lender requires the policy at closing.

How to get flood insurance

Most flood policies are sold through the National Flood Insurance Program by regular insurance agents. Ask the agent who handles your home or car insurance, or find one through FloodSmart.gov, FEMA's official flood insurance site. Private flood insurers also sell policies in many areas and are worth comparing.
