The Flood Insurance Study for Lake County, California and Incorporated Areas dated October 17, 1978, and all subsequent amendments and revisions, and the accompanying Flood Insurance Rate Maps (FIRM), and all subsequent amendments and revisions to such maps, are hereby adopted by reference as a part of these regulations and serve as the basis for establishing flood hazard areas. Where the building code establishes flood hazard areas, such areas are established by this section. Additional maps and studies, when specifically adopted, supplement the FIS and FIRMs to establish additional flood hazard areas. Maps and studies that establish flood hazard areas are on file at Clearlake City Hall at 14050 Olympic Drive. (Ord. #256-2021, S2 (102-2))
