(A) Application for a floodplain development permit must be made on the forms provided by the Floodplain Administrator. Permit applications must be completed in full and must include all documentation needed to demonstrate compliance with the regulations contained within this chapter. At minimum the following information will be required:
(1) A site plan 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;
(2) Elevation (in relation to mean sea level), of the lowest floor (including basement) of all new and substantially improved structures;
(3) Elevation in relation to mean sea level to which any nonresidential structure shall be floodproofed;
(4) A certificate from a registered professional engineer or architect that the nonresidential floodproofed structure shall meet the floodproofing criteria of § 152.076;
(5) Description of the extent to which any watercourse or natural drainage will be altered or relocated as a result of proposed development; and
(6) Maintain a record of all such information in accordance with § 152.041.
(B) The documentation required will differ based on the nature of the proposed development, and the determination as to what documentation is required will be made by the Floodplain Administrator. For any type of development, the Floodplain Administrator may require submission of a detailed site plan prepared by an appropriate design professional that documents the location of any proposed development in relation to the location of floodways, floodplain zones and any natural or human-made feature that may have a bearing on the issuance of a floodplain development permit. The Floodplain Administrator may also require the submission of topographic data to support a permit application.
(C) The Floodplain Administrator may, at any time, choose to rely on the best available data in order to make a decision regarding approval or denial of a permit application. Additionally, any permit application may be approved with conditions or restrictions. These conditions or restrictions shall be considered accepted by the applicant upon issuance of the permit and commencement of work. Failure to comply with such conditions or restrictions invalidates the permit and is considered to be a violation subject to criminal prosecution and/or administrative action.
(D) Approval or denial of a floodplain development permit by the Floodplain Administrator shall be based on all of the provisions of this chapter and the following relevant factors:
(1) The danger to life and property due to flooding or erosion damage;
(2) The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(3) The danger that materials may be swept onto other lands to the injury of others;
(4) The compatibility of the proposed use with existing and anticipated development;
(5) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(6) 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;
(7) The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site;
(8) The necessity to the facility of a waterfront location, where applicable; and
(9) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use.
