15.74.110 Development permit.
A development permit shall be obtained before any construction or other development, including manufactured homes, within any area of special flood hazard established in Section 15.74.040. Application for a development permit shall be made on forms furnished by the city. The applicant shall provide the following minimum information:
A. Plans in duplicate, drawn to scale, showing:
1. Location, dimensions, and elevation of the area in question, existing or proposed structures, storage of materials and equipment and their location;
2. Proposed locations of water supply, sanitary sewer, and other utilities;
3. Grading information showing existing and proposed contours, any proposed fill, and drainage facilities;
4. Location of the regulatory floodway when applicable;
5. Base flood elevation information as specified in Section 15.74.040 or 15.74.100(C);
6. Proposed elevation in relation to mean sea level, of the lowest floor (including basement) of all structures; and
7. Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed, as required in Section 15.74.120(C)(2) and detailed in FEMA Technical Bulletin TB 3-93.
B. Certification from a registered civil engineer or architect that the nonresidential floodproofed building meets the floodproofing criteria in Section 15.74.120(C)(2).
C. For a crawlspace foundation, location and total net area of foundation openings as required in Section 15.74.120(C)(3) and detailed in FEMA Technical Bulletins 1-93 and 7-93.
D. For alteration of a watercourse, an engineering analysis prepared in accordance with standard engineering practices that describes the extent to which any watercourse will be altered or relocated as a result of proposed development, and demonstrates the flood carrying capacity of the altered or relocated portion of the watercourse will not be decreased, and certification that the altered watercourse shall be maintained in a manner which preserves the channel’s flood carrying capacity. The applicant shall submit the analysis to FEMA as specified in subsection F of this section.
E. All appropriate certifications listed in Section 15.74.100(E).
F. Submission of Additional Data. When additional hydrologic, hydraulic or other engineering data, studies, and additional analyses are submitted to support an application, the applicant has the right to seek a letter of map change from FEMA to change the base flood elevations, change floodway boundaries, or change boundaries of flood hazard areas shown on FIRMs, and to submit such data to FEMA for such purposes. The analyses shall be prepared by a qualified registered professional engineer in a format required by FEMA. Submittal requirements and processing fees shall be the responsibility of the applicant. Provided FEMA issues a conditional letter of map revision, construction of proposed flood control projects and land preparation for development are permitted, including clearing, excavation, grading, and filling. Permits for construction of buildings shall not be issued until the applicant satisfies the FEMA requirements for issuance of a letter of map revision. (Ord. 5062 § 1, 2021; Ord. 4469 § 1, 2007)
