A. Appointment: The city of Three Forks zoning official shall hereby be appointed as city floodplain administrator (FPA) and will administer and implement this chapter by granting or denying development permit applications in accordance with its provisions.
B. Duties And Responsibilities: Duties of the city floodplain administrator shall include, but not be limited to:
1. Permit Review:
a. Review all development permits to determine that the permit requirements of this chapter have been satisfied.
b. Review all development permits to determine that all necessary permits have been obtained from federal, state, or local governmental agencies from which prior approval is required, including section 404 of the federal water pollution control act amendments of 1972.
c. Review all development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of section 12-1-9 of this chapter are met.
2. Maintain Records: Keep a record of all permits, appeals, variances and such other transactions and correspondence pertaining to the administration of this chapter.
3. Use Of Other Base Flood Data: When base flood elevation data has not been provided in accordance with subsection 12-1-5B of this chapter, the city floodplain administrator shall obtain, review and reasonably utilize any base flood elevation and floodway data available from any federal, state, or other source as criteria for requiring that new construction, substantial improvements, or other development in zone A are administered in accordance with section 12-1-9 of this chapter.
4. Information Obtained And Maintained:
a. Obtain and record the actual elevation (in relation to mean sea level) of the lowest floor (including basement) of all new or substantially improved structures, and whether the structure includes a basement. The FEMA elevation certificate shall be completed for all new or substantially improved structures.
b. For all new or substantially improved floodproofed structures:
(1) Verify and record the actual elevation (in relation to mean sea level) to which the structure has been floodproofed.
(2) Maintain the floodproofing certifications required in subsection 12-1-9E of this chapter.
c. Maintain for public inspection all records pertaining to the provisions of this chapter.
5. Alteration Of Watercourses:
a. Notify adjacent communities and the state of Montana department of natural resources and conservation floodplain administrator prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the federal emergency management agency.
b. Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood carrying capacity is not diminished.
6. Interpretation Of FIRM Boundaries: Make interpretations, where needed, as to the exact location of the boundaries of the areas of special flood hazard (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). For the purposes of administering this chapter, the floodplain administrator will determine the floodplain zone in which the development activity is proposed, interpret floodplain boundaries and provide flood hazard and flood protection elevation information. When available, the FPA shall use the floodway data table to determine floodway width, and the flood profiles to determine BFEs. When FEMA has not provided BFEs, the FPA shall use best available data. When no best available data exists, the FIRM/FHBM shall be used. The person contesting an elevation or location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in section 12-1-8 of this chapter.
