13.10.190 Duties and responsibilities of the floodplain administrator

13.10.190 Duties and responsibilities of the floodplain administrator.

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 (44 CFR Section 60.3(a)(2));

(3) The site is reasonably safe from flooding (44 CFR Section 60.3(a)(3));

(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 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 (1) foot at any point (44 CFR Section 60.3(c)(10).

(B) Substantial Improvement and Substantial Damage Assessments. Review all development permits for improvements and/or damages to existing structures to determine if the application of the substantial improvement rules apply, including establishing a definition of market value determination and verifying the estimated improvement and/or repair costs meet the ordinance definition of substantial improvement.

(C) Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 13.10.070 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 Article III of this chapter. Any such information shall be consistent with the requirements of FEMA and the director of water resources and shall be submitted to the floodplain board for adoption (44 CFR Section 60.3(b)(4)).

(D) Obtain and Maintain for Public Inspection. Obtain and maintain for public inspection and make available the following:

(1) The certified regulatory flood elevation required in Section 13.10.200(C)(1) and (C)(2) (A.R.S. § 48-3609);

(2) The floodproofing certification required in Section 13.10.200(C)(3);

(3) The certified flood openings required in Section 13.10.200(C)(4)(b);

(4) Certification of elevation required in Section 13.10.170(D);

(5) Certification for floodway encroachment in Section 13.10.260;

(6) Records of all variance actions, including justification for their issuance; and

(7) Obtain and maintain improvement and damage calculations required in subsection (B) of this section.

(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 Insurance Administration through appropriate notification means (44 CFR Section 60.3(b)(6); and

(b) Assure that the flood carrying capacity of the altered or relocated portion of said watercourse is maintained (44 CFR Section 60.3(b)(7)).

(a) Base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six (6) 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 44 CFR 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 one hundred twenty (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 (A.R.S. §§ 48-3605(A) and 48-3609(I)).

(a) Notify the Federal Emergency Management Agency of acquisition, by means of annexation, incorporation or otherwise, of additional areas of jurisdiction.

(F) Advise the flood control district of Navajo County and any adjunct jurisdiction having responsibility for floodplain management in writing and provide a copy of the development plan of all applications for floodplain use permits or variances to develop land in a floodplain or floodway within one (1) mile of the corporate limits of the City of Show Low. Also, advise the flood control district of Navajo 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 (3) working days after having been received by the City of Show Low (A.R.S. § 48-3610(B)(2)).

(G) Map Determinations. 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). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in Article IV of this chapter.

(H) Remedial Actions. Take actions on violations of this chapter as required in Section 13.10.150. (Ord. No. 2004-16, § 4, 8-17-04; Ord. No. 2005-18, § 2, 6-21-05; Ord. No. 2015-05, §§ 1 – 4, 7-21-15. 1976 Code § 19-4-3)
