Establishment of development permit:
A. Permit: A development permit shall be obtained before construction or development begins within any area of a special flood hazard established in subsection 3-3-3B of this chapter. 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:
1. Proposed elevation in relation to mean sea level, of the lowest habitable floor (including basements) of all structures; in zone AO, elevation of existing grade and proposed elevation of lowest habitable floor of all structures;
2. Proposed elevation in relation to mean sea level to which any structure will be floodproof;
3. Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in subsection 3-3-5A3c of this chapters; and
4. Description of the extent to which any watercourse will be altered or relocated as a result of proposed development.
B. Duties And Responsibilities Of The Floodplain Administrator: Duties of the floodplain administrator shall include, but not be limited to:
1. Review all development permits to determine that the permit requirements of this ordinance have been satisfied.
2. Review all permits to determine that the site is reasonably safe from flooding.
3. Review all development permits to determine if the proposed development adversely affects the flood carrying capacity of the area of a special flood hazard. For purposes of this ordinance, "adversely affects" means that the cumulative effects 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 (1') at any point.
C. Use Of Other Base Flood Data: When base flood elevation data has not been provided in accordance with subsection 3-3-3B, "Basis For Establishing The Areas Of Special Flood Hazard", of this chapter the floodplain administrator shall utilize any base flood elevation data available from a federal, state or other source, on order to administer section 3-3-5 of this chapter. Any such information shall be submitted to the floodplain board for adoption.
D. 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 subsection 3-3-5A3a of this chapter;
2. The certification required in subsection 3-3-5A3b of this chapter;
3. The floodproofing certification required in subsection 3-3-5A3c of this chapter; and
4. The certified elevation required in section 3-3-5D2 of this chapter. (Ord. 1-1983, 2-16-1983)
E. Alteration Of Watercourses:
1. Notify adjacent communities and the Arizona department of water resources prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the federal insurance administration; and
2. Require that the flood carrying capacity of the altered or relocated portion of said watercourse is maintained.
F. Construction Of Flood Control Protective Works: Within one hundred twenty (120) days after completion of construction of any flood control protective works which changes the rate of flow during flooding 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.
G. Development Plan: Advise the flood control district of Cochise County and any adjunct jurisdiction having responsibility for floodplain management in writing and provide a copy of a 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 city of Tombstone. Also, advise the flood control district of Cochise 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 floodplain administrator.
H. 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 section 3-3-6 of this chapter.
I. Violations: Take actions on violations of this chapter as required in subsection 3-3-3I of this chapter. (Ord. 1-1983, 2-16-1983)
