Duties and responsibilities of the Floodplain Administrator shall include, but not be limited to, the following:
(A) Maintain and hold open for public inspection all records pertaining to the provisions of this chapter;
(B) Review permit application to determine whether proposed building site will be reasonable safe from flooding;
(C) Review, approve, or deny all applications for development permits required by adoption of this chapter;
(D) Review permits for proposed development to assure that all necessary permits have been obtained from those federal, state, or local governmental agencies including § 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. § 1344, from which prior approval is required;
(E) Where interpretation is needed as to the exact location of the boundaries of the areas of special flood hazards for example, where there appears to be a conflict between a mapped boundary and actual field conditions the Floodplain Administrator shall make the necessary interpretation;
(F) Notify, in riverside situations, adjacent communities and the State Coordination Agency, which is the State Water Resources Board prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency;
(G) Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained;
(H) When base flood elevation data has not been provided in accordance with this section the Floodplain Administrator shall obtain, review, and reasonably utilize any base flood elevation data and floodway data available from a federal, state, or other source, in order to administer the provisions;
(I) In unnumbered A Zones, flood hazard areas without base flood elevations where the best available data must be used, one of the following actions is required as a condition of a permit:
(1) Determine an elevation from the nearest benchmark outside of the flood hazard area. The lowest floor of the structure in the unnumbered A Zone must be tow foot or more above such elevation;
(2) Where flooding history is greater than the above elevation, the lowest floor elevation must be two feet or more above such level of historical flooding;
(3) The elevation of the lowest floor must be two or more feet above the highest adjacent grade next to the building site; and
(4) The base flood elevation be established thought an engineering study. The lowest floor elevation must be two feet or more above the base flood elevation.
(J) When a regulatory floodway has not been designated, the Floodplain Administrator must require that no new construction, substantial improvements, or other development including fill shall be permitted within Zones A1-30 and AE on the community’s FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than two feet at any point within the community.
