Figure 1.,32 Flood Insurance Rate Map Figure 1.33 Flood Boundary and Floodway Map FIRMs generally show flood-prone areas as either A-Zones or V-Zones, Riverine flood-prone areas and coastal flood-prone areas subject to storm surges with velocity waves of less than three feet during the 1 DO-year flood are generally class- ed as A,Zones. "Coastal high hazard areas" are shown on FIRM's as V-Zones, The V-Zone is the portion of the floodplain subject to storm surges with velocity waves of three feet or more during the 1 DO-year flood, Based on this informatio",--regulatory standards that are more detailed than Emergency Program requirements are adopted and enforced by the participating community, These standards include requirements that influence the location and man- ner of installation of manufactured homes. The technical guidelines contained in this manual can be used in complying with the NFIP performance standards, Also, local community of- ficials should be contacted to determine what NFIP regulations govern the placement of manufactured homes in flood hazard areas, State and Local Regulations-Some states have regulations, as shown in Figure 1 ,34, apply- ing to the placement of manufactured homes in flood hazard areas, Figure 1.34 State and Local Regulations New Mexico, for example. requires manufac- tured home dealers to provide the purchaser with a notice to check with the local government to determine installation requirements in a flood hazard area, In Texas, North Carolina, and several other states, when more than one-fourth of the manufactured home frame members are more than three feet above grade, the foundation system must be designed by a registered profes- sional engineer or architect. The appropriate state government departments responsible for manufactured housing installation, floodplain management, water resources, building codes, or coastal zone management should be consulted prior to installation of a manufactured home in a flood hazard area, Each state also has designated a state coor- dinating agency to assist in the implementation of the NFIP, This agency is a focal point for informa- tion on flood insurance, floodplain management, and coordination of the diverse state agencies with responsibilities for riverine and coastal floodplains, A listing of state coordinating agencies is included in Appendix B, The authority of each state's coordinating agency varies and can best be determined through direct contact. These agencies can be important sources of physical data, information on communi- ty eligibility for flood insurance, state regulations, references to other agencies and, in some in- stances, technical assistance, Local governments play the key role in floodplain management.
