(1) Becoming accredited by the OWRB in accordance with 82 O.S. §§ 1601 through 1618, as amended;
(2) Reviewing permit applications to determine whether the proposed building sites, including the placement of manufactured homes, will be reasonably safe from flooding;
(3) Reviewing, approving, or denying all applications for floodplain development permits required by this chapter;
(4) Reviewing proposed development to assure that all necessary permits have been obtained from those local, federal, or state governmental agencies from which prior approval are required;
(5) Making the necessary interpretation where interpretation is 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);
(6) Notifying, in riverine situations, adjacent communities, and the OWRB prior to any alteration or relocation of a watercourse, and submit evidence of such notification to FEMA;
(7) Assuring that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained;
(9) When a floodway has not been designated, the Floodplain Administrator must require that no new construction, substantial improvements, or other development (including fill) be permitted within Zone AE as delineated on the city FIRM, unless it is demonstrated 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 by more than one foot at any point within Zone A in the city;
(10) After a disaster or other type of damage occurrence to structures in the city, determine if the residential and nonresidential structures and manufactured homes have been substantially damaged, and enforce the substantial improvement requirement;
(11) Maintaining a record of all actions involving an appeal from a decision of the City Board of Adjustments; and
(12) Maintaining and holding open for public inspection all records pertaining to the provisions of this chapter.
(C) Permit procedures.
(1) An application for a floodplain development permit shall be presented to the Floodplain Administrator on forms furnished by the Administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the location, dimensions, and elevation of proposed landscape alterations, existing and proposed structures, including the placement of manufactured homes, and the location of the foregoing in relation to areas of special flood hazard. Additionally, the following information is required:
(a) Elevation in relation to mean sea level of the lowest floor (including basement) of all new and substantially improved structures; and
(b) Description of the extent to which any watercourse or natural drainage will be altered or relocated as a result of proposed development.
(2) Approval or denial of a floodplain development permit by the Floodplain Administrator or the City Floodplain Management Board shall be based on all of the provisions of these regulations and the following relevant factors:
(a) The danger to life and property due to flooding or erosion damage;
(b) The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(c) The danger that materials may be swept onto other lands to the injury of others;
(d) The compatibility of the proposed use with existing and anticipated development;
(e) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(f) The costs of providing governmental services during and after flood conditions including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical, and water systems;
(g) The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site;
(h) The necessity to the facility of a waterfront location, where applicable;
(i) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use; and
(j) The relationship of the proposed use to the comprehensive plan for that area.
(3) The Floodplain Administrator or City Council, as applicable, may approve certain development in Zone A delineated on the city’s FIRM which may increase the water surface elevation of the base flood by more than one foot, provided that the applicant for the development permit in that case first complies with 44 C.F.R. § 65.12.
