A. Establishment of Development Permit. A development permit shall be obtained before construction or development begins within any area of special flood hazard established in Section 15.10.060.B. The permit shall be for all structures including manufactured homes, as set forth in the Definitions, and for all other development including fill and other activities, also set forth in Definitions.

Application for a development permit shall be made on forms furnished by the Building Official 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:

1. Elevation in relation to mean sea level, of the lowest floor (including basement) of all structures;

2. Elevation in relation to mean sea level to which any structure has been flood-proofed;

3. Certification by a registered professional engineer or architect that the flood-proofing methods for any nonresidential structure meet the flood-proofing criteria in Section 15.10.090.B.2;

4. Description of the extent to which any watercourse will be altered or relocated as a result of proposed development.

B. Designation of the Building Official. The Building Official is hereby appointed to administer and implement this Chapter by granting or denying development permit applications in accordance with its provisions.

C. Duties and Responsibilities of the Building Official. Duties and responsibilities of, the Building Official shall include, but not be limited to:

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 flood way. If located in the flood way, assure that the encroachment provisions of Section 15.10.080.C.1 are met.

2. Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 15.10.060.B, “Basis for Establishing the Areas of Special Flood Hazard”, the Building Official shall obtain, review, and reasonably utilize any base flood elevation and flood-way data available from a federal, state or other source, in order to administer Sections 15.10.080.B.1 “Specific Standards: Residential Construction”, 15.10.080.B.2 “Specific Standards: Nonresidential Construction, and 15.10.080.C “Flood-ways”.

3. Information to be Obtained and Maintained.

b. For all new 6r substantially improved flood-proofed structures:

(i) Verify and record the actual elevation (in relation to mean sea level); and

(ii) Maintain the flood proofing certifications required in Section 15.10.070.A.3.

c. Maintain for public inspection all records pertaining to the provisions of this Section.

4. Alteration of Watercourses.

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 15.10.090.
