Duties of the Floodplain Administrator shall include but not be limited to:
(A) Permit review. Review all development permits to determine that:
(1) The permit requirements of this chapter have been satisfied;
(2) All other required state and federal permits have been obtained;
(3) The site is reasonably safe from flooding; and
(4) The proposed development does not adversely affect the carrying capacity of the floodway. For purposes of this chapter, ADVERSELY AFFECTS means 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 one foot at any point.
(B) Use of other base flood data. When base flood elevation data has not been provided in accordance with § 151.06, the Floodplain Administrator shall obtain, review and reasonably utilize any base flood elevation data available from a federal, state or other source, in order to administer §§ 151.40 through 151.45. Any information shall be submitted to the Floodplain Board for adoption;
(C) Information to be obtained and maintained. Obtain and maintain for public inspection and make available as needed for flood insurance policies:
(1) The certified elevation required in § 151.40(C)(1);
(2) The certification required in § 151.40(C)(2);
(3) The floodproofing certification required in § 151.40(C)(3); and
(4) The certified elevation required in § 151.43(B).
(D) Alteration of watercourses. Whenever a watercourse is to be altered or relocated:
(1) Notify adjacent communities and the State Department of Water Resources prior to the alteration or relocation of a watercourse, and submit evidence of that notification to the Federal Insurance Administration; and
(2) Require that the flood carrying capacity of the altered or relocated portion of the watercourse is maintained.
(E) Delineation of floodplains affected. Within 120 days after completion of construction of any flood control protective works which changes the rate of flow during the flood or the configuration of the floodplain upstream or downstream from or adjacent to the project, the person or agency responsible for installation of the project shall provide to the governing bodies of all jurisdictions affected by the project a new delineation of all floodplains affected by the project. The new delineation shall be done according to the criteria adopted by the Director of Water Resources;
(F) Written notice of Development Plan. Advise the flood control district of the county and any adjunct jurisdiction having responsibility for floodplain management in writing and provide a copy of Development Plan of all applications for floodplain use permits or variances to develop land in a floodplain or floodway within one mile of the corporate limits of the town. Also, advise the Flood Control District of this county in writing and provide a copy of any development plan of any major development proposed within a floodplain or floodway which could affect floodplains, floodways or watercourses within the district’s area of jurisdiction. Written notice and a copy of the plan of development shall be sent to the District no later than three working days after having been received by the town;
(G) Interpretation of FIRM boundaries. Make interpretations where 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 person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in §§ 151.60 and 151.61; and
