1.Proposed elevation in relation to mean sea level (by licensed surveyor) of the lowest floor (including basement) of all structures; in Zone A0 elevation of highest adjacent grade and proposed elevation of lowest floor of all structures;

2.Proposed elevation in relation to mean sea level to which any structure will be floodproofed;

3.For all proposed structures, spot ground elevations at building corners and 20-foot or smaller intervals along the foundation footprint, or one-foot contour elevations throughout the building site; and

4.Proposed locations of water supply, sanitary sewer, and utilities; and

5.If available, the base flood elevation from the Flood insurance Study and/or Flood Insurance Rate Map; and

6.If applicable, the location of the regulatory floodway; and

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

2.for a crawl-space foundation, location and total net area of foundation openings as required in Section 9-71.1.C.3 of this ordinance and FEMA Technical Bulletins 1-93 and 7-93; and

3.for foundations placed on fill, the location and height of fill, and compaction requirements (compacted to 95 percent using the Standard Proctor Test method); and

1.review all development permits to determine that the permit requirements of this ordinance have been satisfied;

2.all other required state and federal permits have been obtained;

3.the site is reasonably safe from flooding;

4.the proposed development does not adversely affect the carrying capacity of areas where base flood elevations have been determined but a floodway has not been designated. For purposes of this ordinance, “adversely affects” 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 foot at any point.

1.When base flood elevation data has not been provided in accordance with Section 9-69.2, the applicant shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a Federal, State or other source, in order to administer Section 9-71. Any such information shall be submitted to the Planning Commission for adoption and the Flood Administrator shall reasonably utilize said information; or

2.If no base flood elevation data is available from a federal or state agency or other source, then a base flood elevation shall be obtained using one of two methods from the FEMA publication “Managing Floodplain Development in Approximate Zone A Areas - A Guide for Obtaining and Developing Base (100-year) Flood Elevations” dated July 1995 in order to administer Section 9-71:

1.Notify adjacent communities and the California Department of Water Resources prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration;

2.Require that the flood carrying capacity of the altered or relocated portion of said watercourse is maintained.

1.the certification required in Section 9-71.1.C.1 and Section 9-71.4 (lowest floor elevations);

2.the certification required in Section 9-71.1.C.2 (elevations or floodproofing of nonresidential structures);

3.the certification required in Section 9-71.1.C.3 (elevation or floodproofing of nonresidential structures);

4.the certification required in Section 9-71.1.C.4(a) or Section 9-71.1.C.4(b) (wet floodproofing standard);

5.the certified elevation required in Section 9-71.3 (subdivision standards);

6.the information required in Section 9-71.5 (coastal construction standards).
