(A) These regulations apply only to the flood hazard areas specifically adopted herein as regulated flood hazard areas and are more fully and specifically described in §§ 11-1-45 through 11-1-47 of this chapter. The requirements and approvals for alterations to the specific jurisdictional area are in §§ 11-1-45 through 11-1-47 of this chapter as well. Areas within the regulated flood hazard area also include areas specifically identified, labeled and illustrated on maps as floodway or flood fringe that have differing uses allowed and minimum building standards that apply. The jurisdictional areas are those areas of the 100-year floodplain illustrated and depicted in the referenced studies and maps.
(B) The regulated flood hazard area supporting study and maps illustrating the regulatory area are generally studies and maps completed for the DNRC by FEMA or the Natural Resources and Conservation Service (NRCS) that have been adopted by DNRC pursuant to MCA 76-5-201 et seq. The regulated flood hazard area may include those areas collectively identified as special flood hazard areas by FEMA on Flood Insurance Rate Maps and are those areas subject to flood hazard caused by the 100-year flood. FEMA also utilizes the maps of special flood hazard areas and accompanying flood insurance studies for determining flood risk for National Flood Insurance premiums. The maps and accompanying study becomes the regulatory flood hazard area only when formally adopted by DNRC and community within an ordinance.
