A development permit shall be obtained before any construction or other development begins within any special flood hazard area established in § 152.07. Application for a development permit shall be made on forms furnished by Floodplain Administrator prior to any development activities and may 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, fill, storage of materials, drainage facilities; and the location of the foregoing. Endorsement of the Administrator is required before a state floodplain construction permit can be processed. Specifically, the following information is required.
(A) Application stage.
(1) Proposed elevation in relation to mean sea level (MSL) of the proposed lowest floor (including basement) of all structures in Zone A and elevation of highest adjacent grade; or
(2) Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed;
(3) All appropriate certifications from a registered professional engineer or architect that the nonresidential floodproofed structure will meet the floodproofing criteria in § 152.31 (B) and § 152.33(B);
(4) Description of the extent to which any watercourse will be altered or relocated as a result of proposed development.
(B) Construction stage.
(1) Upon placement of the lowest floor, and before construction continues, or floodproofing by whatever construction means, it shall be the duty of the permit holder to submit to the Floodplain Administrator and to the state a certification of the elevation of the lowest floor or floodproofed elevation, as built, in relation to mean sea level. In AE, Al-30, AH, and A Zones where the community has adopted a regulatory base flood elevation, said certification shall be prepared by or under the direct supervision of a registered land surveyor or professional engineer and certified by same.
(2) When floodproofing is utilized for a particular structure, said certification shall be prepared by or under the direct supervision of a certified professional engineer or architect. Any continued work undertaken prior to the submission of the certification shall be at the permit holder’s risk. The Floodplain Administrator shall review the lowest floor and floodproofing elevation survey data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to further progressive work being permitted to proceed. Failure to submit the survey or failure to make said corrections required hereby, shall be cause to issue a stop- work order for the project.
