A development permit shall be obtained before construction or development begins within any area of special flood hazard established in RDMC § 15.15.070. 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 elevations 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:
(1) 
Proposed elevation in relation to mean sea level of the lowest floor (including basement) of all structures;
(2) 
Proposed elevation in relation to mean sea level to which any structure will be floodproofed;
(3) 
All appropriate certifications listed in RDMC § 15.15.140(4); and
(4) 
Description of the extent to which any watercourse will be altered or relocated as a result of proposed development.
(Ord. 235 § 4.1, 1999)
The duties and responsibilities of the Floodplain Administrator shall include, but not be limited to:
(1) 
Permit Review.
(a) 
Review all development permits to determine that the permit requirements of this chapter have been satisfied;
(b) 
All other required State and Federal permits have been obtained;
(c) 
The site is reasonably safe from flooding;
(d) 
The proposed development does not adversely affect the carrying capacity of the floodway. 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 foot at any point.
(2) 
Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with RDMC § 15.15.070, 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 IV of this chapter. Any such information shall be submitted to the City of Rio Dell for adoption.
(3) 
Whenever a watercourse is to be altered or relocated:
(a) 
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 Administrator;
(b) 
Require that the flood-carrying capacity of the altered or relocated portion of said watercourse is maintained.
(4) 
Obtain and maintain for public inspection and make available as needed:
(a) 
The certification required in RDMC § 15.15.150(3)(a) (lowest floor elevations);
(b) 
The certification required in RDMC § 15.15.150(3)(b)(iii) (elevation or floodproofing of nonresidential structures);
(c) 
The certification required in RDMC § 15.15.150(3)(c)(ii) (wet floodproofing standard);
(d) 
The certified elevation required in RDMC § 15.15.170(2) (subdivision standards);
(e) 
The certification required in RDMC § 15.15.190(1) (floodway encroachments).
(5) 
Make interpretations where needed as to the location of the boundaries of the areas of special flood hazard. Where there appears to be a conflict between a mapped boundary and actual field conditions, grade and base flood elevations shall be used to determine the boundaries of the special flood hazard area. 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.
(6) 
Take action to remedy violations of this chapter as specified in RDMC § 15.15.080 or other applicable law.
