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;
(4) The proposed development does not adversely affect the carrying capacity of areas where base flood elevations have been determined but a floodway has not been designated. For purposes of this chapter, “adversely affect” 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) Substantial improvement and substantial damage procedures.
(1) Develop detailed procedures for identifying and administering requirements for substantial improvement and substantial damage, to include defining “market value.”
(2) Assure procedures are coordinated with other departments and divisions and implemented by community staff.
(C) Use of other base flood data. When base flood elevation data has not been provided in accordance with § 153.07, 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 §§ 153.40 through 153.46. Any such information shall be consistent with the requirements of the Federal Emergency Management Agency and the Director of the Arizona Department of Water Resources and shall be submitted to the Floodplain Board for adoption.
(D) Obtain and maintain for public inspection.
(2) The elevation certification required for additional development standards, including subdivisions, in § 153.43(A);
(3) The floodway encroachment certification required in § 153.46(A);
(4) Maintain a record of all variance actions, including justification for their issuance, and report such variances issued in its biennial report submitted to the Federal Emergency Management Agency; and
(5) Obtain and maintain improvement calculations.
(E) Notification of other entities.
(1) Whenever a watercourse is to be altered or relocated:
(a) Notify adjacent communities and the Arizona Department of Water Resources prior to such alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency through appropriate notification means; and
(b) Assure that the flood carrying capacity of the altered or relocated portion of said watercourse be maintained.
(2) Base flood elevation and rate of flow due to physical alterations:
(a) Base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six months after the date such information becomes available, the Floodplain Administrator shall notify the Federal Emergency Management Agency of the changes by submitting technical or scientific data in accordance with Volume 44 Code of Federal Regulations section 65.3. Such a submission is necessary so that upon confirmation of those physical changes affecting flooding conditions, risk premium rates and floodplain management requirements will be based upon current data.
(b) 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 the Arizona Department of Water Resources.
(3) Corporate boundary changes. Notify the Federal Emergency Management Agency of acquisition by means of annexation, incorporation or otherwise, of additional areas of jurisdiction.
(F) Map determinations. Make interpretations, where needed, as to the exact location of the boundaries of the areas of special flood y 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 §§ 153.60 through 153.62.
(G) Remedial actions. Take actions on violations of this chapter as required in § 153.14.
(H) Biennial report. Complete and submit a biennial report to the Federal Emergency Management Agency.
