The duties and responsibilities of the floodplain administrator shall include, but not be limited to:
A. Permit Review.
1. Review all development permits to determine that the permit requirements of this chapter 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 chapter, “adversely affects. that the cumulative effect of the proposed development when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one foot at any point.
B. Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 15.48.080, the floodplain administrator 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 Article V of this chapter. Any such information shall be submitted to the
City Council
for adoption.
C. Whenever a watercourse is to be altered or relocated:
1. Notify adjacent communities and the California Department of Water Resources prior to such 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.
3. Base Flood Elevation changes due to physical alterations:
a. Within six (6) months of information becoming available or project completion, whichever comes first, the Floodplain Administrator shall submit or assure that the permit applicant submits technical or scientific data to FEMA for a Letter of Map Revision (LOMR).
b. All LOMR's for flood control projects are approved prior to the issuance of building permits. Building Permits must not be issued based on Conditional Letters of Map Revision (CLOMR's). Approved CLOMR's allow construction of the proposed flood control project and land preparation as specified in the "start of construction" definition.
Such submissions are necessary so that upon confirmation of those physical changes affecting flooding conditions, risk premium rates and floodplain management requirements are based on current data.
4. Changes in corporate boundaries. Notify FEMA in writing whenever the corporate boundaries have been modified by annexation or other means and include a copy of a map of the community clearly delineating the new corporate limits.
D. Obtain and maintain for public inspection and make available as needed:
1. The certification required in Section 15.48.170(C)(1) (floor elevations);
2. The certification required in Section 15.48.170(C)(2)(c) (elevation or floodproofing of nonresidential structures);
3. The certification required in Sections 15.48.170(C)(3)(a) or 15.48.170 (C) (3) (b) (wet floodproofing standard);
4. The certified elevation required in Section 15.48.190(B) (subdivision standards);
5. The certification required in Section 15.48.210(A) (floodway encroachments);
6. The information required in Section 15.48.220 (coastal construction standards).
E. Make interpretations where needed, as to the 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 Article VI of this chapter.
F. Take action to remedy violations of this chapter as specified in Section 15.48.090 herein.
