335-4. Administration.
(a) Flood Plain Development Permit. A flood plain development permit shall be obtained before construction or development begins within any area of special flood hazard established in Section 335-3. Application for a development permit shall be made on forms furnished by the Director and may include, but not be limited to: duplicate plans in 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:
(1) Proposed elevation in relation to mean sea level, of the lowest floor (including basement) of all structures in areas designated AO on the FIRM map, elevation of/existing grade and proposed elevation of lowest floor of all structures;
(2) Proposed elevation in relation to mean sea level to which any proposed structure will be floodproofed;
(3) Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in Section 335-5; and
(4) Description of the extent to which any watercourse will be altered or relocated as a result of proposed development.
(b) Designation of the Administrator. The Building Official of the Planning and Building department is appointed to administer and implement this chapter by granting or denying flood plain development permit applications in accordance with its provisions. (Ord. 2560, § 1, 10/4/2016)
(c) Duties of the Building Official. Duties and responsibilities of the Building Official shall include, but not be limited to the following: (Ord. 2560, § 1, 10/04/2016)
(1) Permit Review. The Building Official shall: (Ord. 2560, § 1, 10/04/2016)
(A) Review all flood plain development permits to determine that the requirements of this chapter have been satisfied.
(B) Review all permits to determine that the site is reasonably safe from flooding.
(C) Review all flood plain development permits to determine that 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. This means 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 (1') at any point within the County of Humboldt. (Ord. 2560, § 1, 10/4/2016)
(D) Review proposed development to assure that all necessary permits have been received from those governmental agencies from which approval is required by Federal or State law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972.
(E) Review subdivision proposals and other proposed new development, including manufactured home parks or subdivisions, to assure that adequate drainage is provided to reduce flood hazards.
(2) Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 335-3(b), Basis for Establishing the Areas of Special Flood Hazard, the Building Official shall obtain, review, and reasonably use any base flood elevation data available from a Federal, State or other source, in order to administer Sections 335-5 and 322-4. (Ord. 2560, § 1, 10/4/2016)
(3) Information to be obtained and maintained. The Building Official shall obtain and maintain for public inspection and make available as needed for flood insurance policies: (Ord. 2560, § 1, 10/04/2016)
(A) The certified elevation required by Section 335-5(a)(3)a (residential);
(B) The certification required by Section 335-5(a)(3)b (shallow flooding);
(C) The floodproofing certification required by Section 335-5(a)(3)d (nonresidential);
(D) Information required by Section 335-7(f) (coastal construction standards); (Ord. 2560, § 1, 10/4/2016)
(E) The certified elevation required in Section 322-4(b) (subdivision); (Ord. 2560, § 1, 10/4/2016)
(F) The anchoring certification required in Section 335-5(e) (manufactured homes); (Ord. 2560, § 1, 10/4/2016)
(G) The certification required by Section 335-5(a)(3)e (equalization of hydrostatic pressures); and (Ord. 2560, § 1, 10/4/2016)
(H) The certification required by Section 335-6(a) (floodway encroachment). (Ord. 2102, § 7, 1/9/1996; Ord. 2560, § 1, 10/4/2016)
(4) Alteration of Watercourses. The Director shall:
(A) Notify adjacent communities and the State Department of Water Resources prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration; and
(B) Require that the flood-carrying capacity of the altered or relocated portion of said watercourse be maintained.
(C) Base Flood Elevation changes due to physical alterations:
1. Within 6 months of information becoming available or project completion, whichever comes first, the floodplain administer shall submit or assure that the permit applicant submits technical or scientific data to FEMA for a Letter of Map Revision (LOMR). (Ord. 2560, § 1, 10/4/2016)
2. 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. (Ord. 2560, § 1, 10/04/2016)
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. (Ord. 2560, § 1, 10/4/2016)
(Ord. 2560, § 1, 10/4/2016)
(5) Interpretation of FIRM Boundaries. The Building Official shall make interpretations where needed, as to the 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). (Ord. 2560, § 1, 10/4/2016)
(6) Remedial Action. Take action to remedy violations of this ordinance as specified in section 335-3(c). (Ord. 2102, § 7, 1/9/1996)
(d) Fees. The Board of Supervisors shall, by resolution or ordinance, establish fees for these permits and appeals or variances. Such fees shall not exceed the actual cost of administering this chapter. (Ord. 1541, § 4, 7/13/1982)
