Water is welcome in your pools, but not your house.
If you're in a flood prone area, it may be a good idea to get flood insurance. Most flood insurance take up to 30 days to go into effect so waiting until a flood is on the horizon to start a policy is not a good idea. If your home is in a community that is part of the National Flood Insurance Program (NFIP) you may be eligible for flood insurance at a modest cost through the federal government.
