ORDINANCE 2012-036 <br />a. For development activities proposed to be located in a regulatory <br />floodway, a floodway encroachment analysis that demonstrates that <br />the encroachment of the proposed development 'will not cause any <br />increase in base flood elevations. Where the applicant proposes to <br />undertake development activities that do increase base flood <br />elevations, the applicant shall submit such analysis to FEMA as <br />specified in Section 930.07(2)(a)4. of these floodplain regulations and <br />shall submit the Conditional Letter of Map Revision, if issued by <br />FEMA, with the site plan and construction documents. <br />b. For development activities proposed to be located in a riverine flood <br />hazard area for which base flood elevations are included in the Flood <br />Insurance Study or on the FIRM and floodways have not been <br />designated, a floodway encroachment analysis which demonstrates <br />that the cumulative effect of the proposed development, when <br />combined with all other existing and anticipated flood hazard area <br />encroachments, will not increase the base flood elevation more than <br />one 1) foot at any point within the community. This requirement does <br />not apply in isolated flood hazard areas not connected to a riverine <br />flood hazard area or in flood hazard areas identified as Zone AO or <br />Zone AH. <br />c. For alteration of a watercourse, an engineering analysis prepared in <br />accordance with standard engineering�practices which demonstrates <br />that the flood -carrying capacity of the altered or relocated portion of <br />the watercourse will not be decreased, and certification that the altered <br />watercourse shall be maintained in a manner which preserves the <br />channel's flood-carrng capacity, the applicant shall submit the <br />analysis to FEMA as specified in Section 930.07(2)(a)4. of these <br />floodplain regulations. <br />d. For activities that propose to alter sand dunes or mangrove stands in <br />coastal high hazard areas (Zone V), an engineering analysis that <br />demonstrates that the proposed alteration will not increase the <br />potential for flood damage. <br />e. Copies of analyses and correspondence submitted to FEMA shall be <br />provided to the Floodplain Administrator. <br />4. Submission of additional data. When additional hydrologic, hydraulic or <br />other engineering data studies, and additional analyses are submitted to <br />support an application the applicant has the right to seek a Letter of Map <br />Change from FEMA to change the base flood elevations, change floodway <br />boundaries or change boundaries of flood hazard areas shown on FIRMS, <br />and to submit such data to FEMA for such purposes. The analyses shall <br />be prepared by a Florida licensed engineer in a format required by FEMA. <br />Underline: Additions to Ordinance <br />Strike thF@u&.
