(A) Application for a development permit shall be made to the Administrator on forms furnished by the Administrator prior to any development activities. The development permit shall include, but not be limited to, plans in duplicate drawn to scale showing: the nature, location, dimensions, and elevations of the area in question; existing or proposed structures; and the location of fill materials, storage areas, and drainage facilities.
(B) Specifically, the following information is required.
(1) A plot plan that shows the 100-year flood plain contour, or a statement that the entire lot is within the flood plain, must be provided by the development permit applicant when the lot is within or
appears to be within the flood plain as mapped by the Federal Emergency Management Agency or the flood plain identified pursuant to either § 152.32(J) or §§ 152.47 and 152.48. The plot plan must be prepared by or under the direct supervision of a registered land surveyor or professional engineer and certified by same.
(a) The elevation (in relation to mean sea level) of the lowest floor (including basement) of all new and substantially improved structures; and
(b) If the nonresidential structure will be floodproofed in accordance with § 152.46(B), the elevation (in relation to mean sea level) to which the structure will be floodproofed.
(4) Where the base flood elevation data is not provided, the application for a development permit must show construction of the lowest floor at least two feet above the highest adjacent grade.
(5) Where any watercourse will be altered or relocated as a result of proposed development, the application for a development permit shall include: a description of the extent of watercourse alteration or relocation; an engineering report on the effects of the proposed project on the flood-carrying capacity of the watercourse and the effects to properties located both upstream and downstream; and a map showing the location of the proposed watercourse alteration or relocation.
(6) When a structure is floodproofed, the applicant shall provide a floodproofing certificate (F.E.M.A. Form 81-65) from a registered professional engineer or architect that the nonresidential floodproofed structure meets the floodproofing criteria in § 152.46(B).
(7) An elevation certificate (F.E.M.A. Form 81-31) or a floodproofing certificate (F.E.M.A. Form 81-65) is required after the lowest floor is completed. Within 21 calendar days of establishment of the lowest floor elevation, or floodproofing by whatever construction means, whichever is applicable, it shall be the duty of the permit holder to submit to the Administrator a certification of the elevation of the lowest floor, or floodproofed elevation, whichever is applicable, as built, in relation to mean sea level. The certification shall be prepared by or under the direct supervision of a registered land surveyor or professional engineer and certified by same. When floodproofing is utilized for a particular building, the certification shall be prepared by or under the direct supervision of a professional engineer or architect and certified by same. Any work done within the 21-day calendar period and prior to submission of the certification shall be at the permit holder's risk. The Administrator shall review the floor elevation survey data submitted. Deficiencies detected by the 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 the corrections required hereby shall be cause to issue a stop-work order for the project.
