Sec. 29-12. - Establishment of development permit.¶
Any development subject to obtaining a development permit, shall obtain said permit before any construction or other development begins within any areas of special flood hazard established in section 29-7. Application for a development permit shall be made on forms furnished by the floodplain
administrator and may include, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions, and elevation of the area in question existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing. Specifically, the following information is required:
(a)
Proposed elevation in relation to mean sea level, of the lowest floor (including basement) of all structures - in zone AO, elevation of highest adjacent grade and proposed elevation of lowest floor of all structures; or
(b)
Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed, if required in subsection 29-16(c)(2); and
(c)
All appropriate certifications listed in subsection 29-14(d) of this chapter; and
(d)
Description of the extent to which any water-course will be altered or relocated as a result of proposed development.

Sec. 29-14. - Duties and responsibilities of the floodplain administrator.¶
The duties and responsibilities of the floodplain administrator shall include, but not be limited to the following:
(a)
Permit Review. Review all development permits to determine that:
(1)
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; and
(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" 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.
(b)
Review and Use of Any Other Base Flood Data. When base flood elevation data has not been provided in accordance with section 29-7, the floodplain administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal or state agency, or other source, in order to administer article IV of this chapter. Any such information shall be submitted to the city council for adoption.
(c)
Notification of Other Agencies. In alteration or relocation of a watercourse:
(1)
Notify adjacent communities and the California Department of Water Resources prior to alteration or relocation;
(2)
Submit evidence of such notification to the Federal Insurance Administration, Federal Emergency Management Agency; and
(3)
Assure that the flood carrying capacity within the altered or relocated portion of said watercourse is maintained.
(d)
Documentation of Floodplain Development. Obtain and maintain for public inspection and make available as needed the following:
(1)
Certification required by subsection 29-16(c)(1) (lowest floor elevations);
(2)
Certification required by subsection 29-16(c)(2) (elevation or floodproofing or nonresidential structures);
(3)
Certification required by subsection 29-16(c)(3) (wet floodproofing standard);
(4)
Certification of elevation required by subsection 29-18(b) (subdivision standards);
(5)
Certification required by subsection 29-21(a) (floodway encroachments).
(e)
When base flood elevation data has not been provided in accordance with section 29-7, the floodplain administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal or state agency, or other source, in order to administer Article IV. NOTE: A base floor elevation may be obtained using one of the two methods the FEMA publication, FEMA 265, "Managing Floodplain Development in Approximate Zone A Areas—A Guide for Obtaining and Developing Base (100-year) Flood Elevations" dated July 1995.
(f)
Map Determinations. Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazard, 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 V of this chapter.
(g)
Remedial Action. Take action to remedy violations of this chapter as specified in section 29-8.
(Ord. No. 477, § 2, 12-9-2008; Ord. No. 502, § 4, 11-18-2014)
