§ 7-5.501. Establishment of development permit.

A flood area development permit shall be obtained before any construction or other development, including manufactured homes, begins within any special flood hazard area (SFHA) established in Section 7-5.302. Application for a flood area development permit shall be made on forms furnished by the Floodplain Administrator and shall include, but not be limited to:

(a)

Plans in duplicate drawn to scale, including 300 feet surrounding and adjacent to the area in question, showing:

(1)

The nature, location, dimensions, and elevation of the area in question;

(2)

Existing or proposed structures, storage of materials and equipment and the location;

(3)

Proposed locations of water supply, sanitary sewer, and other utilities;

(4)

Grading information showing existing and proposed contours, any proposed fill, and drainage facilities;

(5)

Location of regulatory floodway when applicable;

(6)

BFE information as specified in Section 7-5.302 or Section 7-5.402(c). When not provided according to said sections, the applicant shall provide, upon approval by the City for its use, the best available BFE data from a Federal or State agency or from a private engineering report;

(7)

Proposed elevation in relation to mean sea level of the lowest floor of all structures. In Zone AO, the elevation of highest adjacent grade and proposed elevation of lowest floor of all structures; and

(8)

Proposed elevation in relation to mean sea level to which any non-residential structure will be floodproofed, as required in Section 7-5.603(e)(3) of this chapter and detailed in FEMA Technical Bulletin TB 3-93.

(b)

Certification from a registered civil engineer or architect that the non-residential floodproofed building meets the floodproofing criteria in Section 7-5.603(e)(3).

(c)

For a crawl space foundation, location and total net area of foundation openings as required in Sections 7-5.603(e)(5) and 7-5.603(e)(8) of this chapter and detailed in FEMA Technical Bulletins 1-93 and 7-93.

(d)

All appropriate certifications listed in Sections 7-5-402(e) and 7-5.501 of this chapter.

(e)

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

(1)

Proof that written notification, on forms furnished by the Floodplain Administrator, was sent prior to any alteration or relocation of the watercourse to all adjacent communities, the California Department of Water Resources, and the Federal Insurance Administration, Federal Emergency Management Agency; and

(2)

Engineering data to demonstrate, to the satisfaction of the Floodplain Administrator, that the flood carrying capacity of the altered or relocated portion of the watercourse will be maintained;

(f)

Engineering data to satisfy the following requirements:

(1)

The site is reasonably safe from flooding as required by the provisions of this chapter; and

(2)

The proposed development will not adversely affect the carrying capacity of areas where BFEs have been determined, but a floodway has not been designated. For purposes of this chapter, "adversely affect" means that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will increase the water surface elevation of the base flood more than one-tenth of one foot at any point within the City of Simi Valley.
