Summary

Owners of buildings in the Colorado River Floodway can keep and transfer existing federal flood insurance. If a building was already in the Floodway on October 8, 1986 and did not have federal flood insurance, the owner can buy a policy for six months after the Secretary of the Interior files the required Floodway maps, and then can renew and transfer that policy. No federal flood insurance can be issued for new buildings or major improvements in the Floodway starting six months after October 8, 1986. The Secretary of the Interior may set temporary Floodway boundaries after public notice and comment until the maps are filed. Banks and federal lenders may still make loans on properties that are ineligible for flood insurance, but they must first confirm the property is in the Floodway.
