14.20.010 Designation of the floodplain administrator.
The zoning administrator is hereby appointed to administer, implement and enforce this title by granting or denying development permits in accordance with its provisions. [Ord. 2015-02.]
14.20.020 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 title 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 title, “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 TTC 14.15.020, 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 Chapter 14.25 TTC. 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.
1. The certified regulatory flood elevation required in TTC 14.25.010(C)(2);
2. The floodproofing certification required in TTC 14.25.010(C)(2);
3. The flood vent certification required in TTC 14.25.010(C)(3);
4. The elevation certification required for additional development standards, including subdivisions, in TTC 14.25.040(A)(2);
5. The floodway encroachment certification required in TTC 14.25.070(A);
6. 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
7. 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 44 CFR 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 change 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.
a. Notify the Federal Emergency Management Agency and the Arizona Department of Water Resources 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 hazards (e.g., 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 Chapter 14.35 TTC.
G. Remedial Actions. Take actions on violations of this title as required in TTC 14.15.100.
H. Biennial Report. Complete and submit a biennial report to the Federal Emergency Management Agency. [Ord. 2015-02.]
14.20.030 Establishment of development permit.
A development permit shall be obtained before construction or development begins, including placement of manufactured homes, within any area of special flood hazard established in TTC 14.15.020. Application for a development permit shall be made on forms furnished by the floodplain administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevation of the area in question, existing or proposed structures, fill, storage of materials, drainage facilities and the location of the foregoing. Specifically, the following information is required:
A. Proposed elevation in relation to mean sea level of the lowest floor (including basement) of all structures. In Zone AO, elevation of existing highest adjacent natural grade and proposed elevation of lowest floor of all structures;
B. Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed;
C. Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in TTC 14.25.010(C)(2);
D. Base flood elevation data for subdivision proposals or other development greater than 50 lots or five acres, whichever is the lesser; and
E. Description of the extent to which any watercourse will be altered or relocated as a result of proposed development. [Ord. 2015-02.]
