(A) Information for development in flood hazard areas. The site plan or construction documents for any development subject to the requirements of this chapter shall be drawn to scale and shall include, as applicable to the proposed development:
(1) Delineation of flood hazard areas, flood zone(s), base flood elevation(s), and ground elevations if necessary for review of the proposed development.
(2) Location of the proposed activity and proposed structures, and locations of existing buildings and structures; in coastal high hazard areas, new buildings shall be located landward of the reach of mean high tide.
(3) Location, extent, amount, and proposed final grades of any filling, grading, or excavation.
(4) Where the placement of fill is proposed, the amount, type, and source of fill material; compaction specifications; a description of the intended purpose of the fill areas; and evidence that the proposed fill areas are the minimum necessary to achieve the intended purpose.
(5) Delineation of the coastal construction control line or notation that the site is seaward of the coastal construction control line, if applicable.
(6) Extent of any proposed alteration of sand dunes or mangrove stands, provided such alteration is approved by the Florida Department of Environmental Protection.
(7) Existing and proposed alignment of any proposed alteration of a watercourse.
The Floodplain Administrator, in coordination with the Building Official, is authorized to waive the submission of site plans, construction documents, and other data that are required by this chapter, but that are not required to be prepared by a registered design professional, if it is found that the nature of the proposed development is such that the review of such submissions is not necessary to ascertain compliance with this chapter.
(B) Reserved.
(C) Additional analyses and certifications. As applicable to the location and nature of the proposed development activity, and in addition to the requirements of this section, the applicant shall have the following analyses signed and sealed by a Florida licensed engineer for submission with the site plan and construction documents:
(1) For alteration of a watercourse, an engineering analysis prepared in accordance with standard engineering practices which demonstrates that the flood-carrying capacity of the altered or relocated portion of the watercourse will not be decreased, and certification that the altered watercourse shall be maintained in a manner which preserves the channel's flood-carrying capacity; the applicant shall submit the analysis to FEMA as specified in division (D) of this section.
(2) For activities that propose to alter sand dunes or mangrove stands in coastal high hazard areas (Zone V), an engineering analysis that demonstrates that the proposed alteration will not increase the potential for flood damage.
(D) Submission of additional data. When additional hydrologic, hydraulic or other engineering data, studies, and additional analyses are submitted to support an application, the applicant has the right to seek a letter of map change from FEMA to change the base flood elevations, or change boundaries of flood hazard areas shown on FIRMs, and to submit such data to FEMA for such purposes. The analyses shall be prepared by a Florida licensed engineer in a format required by FEMA. Submittal requirements and processing fees shall be the responsibility of the applicant.
