A. Permit Requirements:
1. Development Permit Required: A development permit shall be obtained before construction or development begins within any area of special flood hazard established in subsection 13-1-6B of this chapter. The permit shall be for all structures including manufactured homes, as set forth in section 13-1-5 of this chapter, and for all development, including fill and other activities, also as set forth in section 13-1-5 of this chapter.
2. Application For Development Permit: Application for a development permit shall be made on forms furnished by the city and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations 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. Elevation in relation to mean sea level, of the lowest floor (including basement) of all structures;
b. Elevation in relation to mean sea level to which any structure has been floodproofed;
c. Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in subsection 13-1-9B2 of this chapter; and
d. Description of the extent to which a watercourse will be altered or relocated as a result of proposed development. (Ord. 463, 5-4-1987)
3. Permit for Storage of Buoyant or Hazardous Materials:
a. A special land use permit, requiring Planning Commission approval, must be obtained prior to storing, placing or stockpiling buoyant or hazardous materials in a flood hazard area.
b. Planning Commission Review of Special Permits to Store, Place or Stockpile Buoyant or Hazardous Materials: In determining whether or not a permit will be permitted to store, place or stockpile buoyant or hazardous materials in a flood hazard area, the Planning Commission shall consider the following:
(1) The nature of the materials; (e.g., buoyancy, toxicity, flammability);
(2) The danger that materials may be swept onto other properties or structures with resulting injury or damage;
(3) The necessity of locating the materials on the particular site, especially in terms of public benefit;
(4) The ability of emergency vehicles to reach the site in times of flooding;
(5) The availability of alternative locations which are less susceptible to flooding; and
(6) The application's plan for hazard mitigation. (Ord. 488-91, 7-8-91)
B. Planning Commission Appointment; Duties: The Planning Commission is hereby appointed to administer and implement this Chapter by granting or denying development permit applications in accordance with its provisions.
C. City Manager; Duties and Responsibilities: Duties of the City Manager shall include, but not be limited to:
1. Permit Review:
a. Review all development permits to determine that the permit requirements of this Chapter have been satisfied.
b. Review all development permits to determine that all necessary permits have been obtained from those Federal, State or local governmental agencies from which prior approval is required.
c. Review all development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of subsection 13-1-9D of this Chapter are met.
2. Use of Other Base Flood Data: When base flood elevation data has not been provided in accordance with subsection 13-1-6B, "Basis for Establishing the Areas of Special Flood Hazard", the City Manager may obtain, review and reasonably utilize any base flood elevation and floodway data available from a Federal, State or other source, in order to administer subsection 13-1-9B of this Chapter, "Specific Standards", and subsection 13-1-9C of this Chapter, "Floodways".
3. Information to be Obtained and Maintained:
a. Where base flood elevation data is provided through the Flood Insurance Study or required as in subsection C2, obtain and record the actual elevation (in relation to mean sea level) of the lowest floor (including basement) of all new or substantially improved structures, and whether or not the structure contains a basement.
b. For all new or substantially improved floodproofed structures:
(1) Verify and record the actual elevation (in relation to mean sea level); and
(2) Maintain the floodproofing certifications required in subsection A2c of this Section.
c. Maintain for public inspection all records pertaining to the provisions of this Chapter.
4. Alteration of Watercourses:
a. Notify adjacent communities and the appropriate State agencies prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.
b. Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood- carrying capacity is not diminished.
5. Interpretation of FIRM Boundaries: Make interpretations, where needed, as to 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 13-1-8 of this Chapter. (Ord. 463, 5-4-87; 1995 Code)
