Application for a floodplain development permit shall be made on forms furnished by the floodplain administrator. The applicant shall furnish all information required to determine compliance with the permitting requirements of this chapter. At a minimum, the application form shall require the applicant to furnish:

A. One (1) or more site plans, drawn to scale, showing:

1. The nature, location, dimensions, and elevations in relation to NAVD88 of the property in question;

2. Names and location of all lakes, water bodies, waterways and drainage facilities within three hundred (300) feet of the site;

3. The elevations of the ten (10), fifty (50), one hundred (100), and five hundred (500) year floods in relation to NAVD88, where such data is available;

4. The boundaries of the SFHA, floodway, wetlands, shoreline buffer, critical areas, and fish and wildlife habitat conservation areas, as defined in this chapter and other ordinances of the city;

5. The proposed drainage system including, but not limited to, storm sewers, overland flow paths, detention facilities and roads; and

6. Existing and proposed structures, fill, pavement and other impervious surfaces, and sites for storage of materials.

B. If the proposed project involves grading, excavation, or filling, the site plan shall include proposed post-development terrain at one (1) foot contour intervals.

C. If the proposed project includes a new structure, substantial improvement, or repairs to a substantially damaged structure, the application shall include the base flood elevation for the building site and the proposed elevations of the following, in relation to NAVD88:

1. The top of bottom floor (including basement, crawlspace, or enclosure floor);

2. The top of the next higher floor;

3. The top of the slab of an attached garage;

4. The lowest elevation of machinery or equipment servicing the structure;

5. The lowest adjacent (finished) grade next to structure;

6. The highest adjacent (finished) grade next to structure; and

7. The lowest adjacent grade at the lowest elevation of a deck or stairs, including structural support.

D. If the proposed project includes a new structure, substantial improvement, or repairs to a substantially damaged nonresidential structure that will be dry floodproofed, the application shall include the base flood elevation for the building site, the elevation to which the structure will be dry floodproofed, and a certification by a registered professional engineer or licensed architect that the dry floodproofing methods meet the floodproofing criteria in Section 15.55.280(B).

E. The applicant for a project to develop in the SFHA shall provide a certification by a registered professional engineer demonstrating through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed development and all other past or future similar developments would not cumulatively result in an increase of flood levels during the occurrence of the base flood by more than one (1) foot.

F. The application shall include a description of the extent to which a stream, lake, or other water body, including its shoreline, will be altered or relocated as a result of the proposed development.

G. The application shall include documentation that the applicant will apply for all necessary permits required by federal, state, or local law. The application shall include written acknowledgment that the applicant understands that the final certification of use or certificate of occupancy will be issued only if the applicant provides copies of the required federal, state, and local permits or letters stating that a permit is not required. A floodplain development permit is not valid if those other permits and approvals are not obtained prior to any ground disturbing work or structural improvements.

H. The application shall include acknowledgment by the applicant that representatives of any federal, state or local unit of government with regulatory authority over the project are authorized to enter upon the property to inspect the development.
