Application for a floodplain development permit shall be made to the Floodplain Administrator for all development activities located wholly within, partially within, or in contact with a SFHA. Such application shall be made by the owner of the property or their authorized agent, herein referred to as the application, prior to the actual commencement of such construction or development on a form furnished for that purpose. Such applications shall include, but not be limited to, the following: plans in duplicate drawn to scale showing the nature, location, dimensions, and elevations of the area in question; existing or proposed structures, earthen fill, storage of materials or equipment, drainage facilities, and the location of the foregoing. Specifically, the following information is required:
(A) Application stage.
(1) A description of the proposed development;
(2) Location of the proposed development sufficient to accurately locate property and structure(s) in relation to existing roads and streams;
(3) A legal description of the property site;
(4) For the reconstruction, rehabilitation, or improvement of an existing structure, or an addition to an existing building, a detailed quote and description of the total work to be completed including but not limited to interior work, exterior work, and labor as well as a certified valuation of the existing (pre-improved or pre-damaged) structure;
(5) A site development plan showing existing and proposed development locations and existing and proposed land grades;
(6) A letter from a licensed professional surveyor or engineering noting that an elevation reference benchmark has been established or confirmed for those projects requiring elevations to be met;
(7) Verification that connection to either a public sewer system or to an approved on-site septic system is available and approved by the respective regulatory agency for proposed structures to be equipped with a restroom, kitchen or other facilities requiring disposal of wastewater;
(8) Plans showing elevation of the top of the planned lowest floor (including basement) of all proposed structures in Zones A, AE, AH. In Zone AO, plans must show the height of the top of the lowest floor above the highest adjacent grade. In Zones V or VE, plans must also show the elevation of the bottom of the lowest supporting horizontal member. Elevation should be in NAVD 88;
(9) Plans showing elevation (in NAVD 88) to which any non-residential structure will be floodproofed;
(10) Plans showing location and specifications for flood openings for any proposed structure with enclosed areas below the flood protection grade;
(11) Plans showing materials to be used below the flood protection grade for any proposed structure are flood resistant;
(12) Plans showing how any proposed structure will be anchored to resist flotation or collapse;
(13) Plans showing how any electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities are designed and/or located. Elevation should be in NAVD 88;
(14) Certification of structural design and methods of construction for VE zone construction as required by § 150.48;
(15) Certification of breakaway wall design, when applicable, as provided in § 150.48);
(16) Description of the extent to which any watercourse will be altered or relocated as a result of proposed development. A hydrologic and hydraulic engineering analysis is required, and any watercourse changes submitted to DNR for approval. Once DNR approval is obtained, a FEMA Conditional Letter of Map Revision must be obtained prior to construction (see § 150.32(B)(6) for additional information);
(17) Any additional information, as requested by the Floodplain Administrator, which may be necessary to determine the disposition of a proposed development or structure with respect to the requirements of this chapter.
(B) Construction stage.
(1) Upon establishment of the lowest floor of an elevated structure or structure constructed on fill, or the placement of lowest supporting horizontal member in V zones, it shall be the duty of the applicant to submit to the Floodplain Administrator an elevation certification for the structure under construction. The Floodplain Administrator shall review the elevation certificate. Any deficiencies detected during the review shall be corrected by the applicant before work is allowed to continue. Failure to submit the survey or elevation certificate, or failure to make said corrections required hereby shall be cause to issue a stopwork order for the project. Any work undertaken prior to submission of the elevation certification shall be at the applicant's risk.
(2) Upon establishment of the floodproofed elevation of a floodproofed structure, it shall be the duty of the applicant to submit to the Floodplain Administrator a floodproofing certificate. Certification shall be prepared by or under the direct supervision of a registered professional engineer and certified by same. (The Floodplain Administrator shall review the floodproofing certification submitted). The applicant shall correct any deficiencies detected by such review before any further work is allowed to proceed. Failure to submit the floodproofing certification or failure to make correction required shall be cause to issue a stopwork order for the project.
(C) Finished construction.
(1) Upon completion of construction of any structure requiring certification of elevation, an elevation certificate which depicts the “as-built” lowest floor elevation, lowest supporting horizontal member for structures in Zones V or VE, and other applicable elevation data is required to be submitted by the applicant to the Floodplain Administrator. The elevation certificate shall be prepared by or under the direct supervision of a registered land surveyor and certified by the same.
(2) Upon completion of construction of an elevated structure constructed on fill, a fill report is required to be submitted to the Floodplain Administrator to verify the required standards were met, including compaction.
(3) Upon completion of construction of a floodproofing measure, a floodproofing certificate is required to be submitted by the applicant to the Floodplain Administrator. The floodproofing certificate shall be prepared by or under the direct supervision of a registered professional engineer or architect and certified by same.
