The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. Structure. A walled and roofed building, that is principally aboveground and affixed to a permanent site, as well as a mobile home on !! foundation. The tenll includes a building while in the course of construction, alteration or repair but does not includc building materials or supplies intended for use in construction, alteration or repair, unless such materials or supplies are within an enclosed building on the premises.

Watercourse includes specifically designated areas in which substantial flood damage may occur. Sec. 8-2. objectives. Statement of purpose and The purpose and objectives of this chapter are to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed: (1) To protect human life and health; (2) To minimize money for projects; expenditure of public costly flood-control (3) To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (4) To mlmmlze prolonged business interruptions; (5) To mmuTIlze damage to public facilities and utilities such as water and gas mains; electric, telephone and sewer lines; streets and bridges located 10 areas of special flood hazard; (6) To help maintain a stable tax base by providing for the second use and development of areas of special flood hazard so as to minimize future flood blight areas; Proposed Revision - 2000 (7) To ensure that potential buyers are notified that property is in an area of special flood hazard; and, (8) To ensure that those who occupy the areas of special flood hazard assume responsibility for their actions. Sec. 8-3. Methods of reducing flood losses. In order to accomplish its purpose and objectives, this chapter includes methods and provisions for: (I) Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities; (2) Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (3) Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel floodwaters; (4) Controlling filling, grading, dredging, and other development which may increase flood damage; and, (5) Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards in other areas. Sec. 8.4. Lands to which this chapter applies. This chapter shall apply to all areas of special flood hazard within the jurisdiction of the city. Sec. 8-5. Basis for establishing areas of special flood hazard.

Sec. 8-8. Warning regarding area of special flood hazard designations. The degree of flood protection required by this chapter is considered reasonable for regulatory Proposed Revision - 2000 purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by manmade or natural causes. This chapter does not imply that land outside the areas of special flood hazard or uses permitted within such areas will be free from flooding or flood damages. This chapter shall not create liabilitv on the part of the City. any officer or employee thereof. the State of Florida. the Federal Insurance Administration. or the Federal Emergency Management Agency. for any flood damages that result from reliance on this Ordinance or any administrative decision lawfully made hereunder. In addition. nothing herein shall be deemed as a waiver of the City's right to sovereign immunity under State and Federal law. Sec. 8-9. Penalties for noncompliance. No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this chapter.

The proposed development does not adversely affect the flood-carrying capacity and/or flood-storage capacity of the areas of special flood hazard. For the purposes of this article. "adversely affect" means damage to adiacent properties because of rises in flood stages attributed to physical changes of the channel and the adiacent overbank areas. Without limiting the foregoing. a development IS presumed to adversely affect the flood-carrying and flood-storage capacities of the flood plain if it proposes or requires the filling of land in an area of special flood hazard without simultaneously providing additional flood-carrying and flood-storage capacities to Proposed Revision - 2000 compensate for that capacity which is lost because of such filling. (2) Interpretation of FIRM boundaries. Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to b~ a conflict between a mapped boundary and actual field conditions). Any person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in section 8-34. (3) Use of other base flood data. To supplement the base flood elevation data provided in accordance with section 8-5, the floodplain damage control administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source (U.S. Army Corps of Engineers, U.S. Geological Survey, U.S. Soil Conservation Service, state water management districts, development plans for more than fifty (50) lots or five (5) acres as criteria for requiring that new construction, substantial improvements, or other development in Zone A meet the requirements of section 8-52(1), specific standards, residential construction, and section 8-52(2). (4) Issuance of permit and record keeping. After ascertaining that all requirements of this chapter have been met, the floodplain damage control administrator may issue the development permit. After issuance of the permit, the local administrator shall: a. Acquire a flood elevation or floodproofing certificate after the lowest floor is completed. Within twenty-one (21) calendar days of establishment of the lowest floor elevation or floodproofing by whatever construction means, it shall be the duty of the permit holder to submit to the city manager a certification of the 8 FLOOD DAMAGE PREVENTION ( elevation of the lowest floor or floodproofed elevation, as built, in relation to mean sea level. Such 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, such 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 twenty-one-day calendar period and prior to submission of the certification shall be at the permit holder's risk. The city manager or designated subordinate shall review the flood 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 surveyor failure to make such corrections required hereby, shall be cause to issue a stop work order for the project. In zono A only, the preceding certification is not required except in those instances in which base flood elevation data are used from sources sup~ental)' to section 8 5. b. Maintain for public inspection all records pertaining to the provisions of this chapter. (5) Control of alteration of watercourses. The local administrator shall: a. Notify adjacent communities, the St. Johns River Water Management District, and the state department of community affairs prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration. Proposed Revision - 2000 b. Require that maintenance is provided within the altered or relocated portion of such watercourse so that the flood carrying capacity is not diminished. (6) Take remedial action on any violations of this chapter. Sec. 8-33. Development permit. (a) Establishment of permit. A development permit shall be obtained before construction or development begins within any area of special flood hazard established in section 8-5. (1) New developments. When new development proposals include lands designated as areas of special flood hazard, the aforementioned development permit shall not be issued until all applicable requirements of Chapter 9 of this Code have been fulfilled. Specifically, the procedures outlined in section 9-10 I (a)(2) shall be required. In addition, the provisions of section 9-241 which exceed the provisions of this chapter, shall apply and be prerequisites to issuance ofthe development permit. (2) Construction in existing developments. Already developed lands within or including areas of special flood hazard in this city for which building pcmlits are requested shall be subject to the provisions of this chapter, as shall lands described in (a) above. After land development is complcted no construction of any nature, neither buildings, nor site preparation, nor modification of existing roads, utilities, drainage systems or other nonstructural improvements shall be allowed within areas of special flood hazard until the development permit herein required has been issued. (b) Application for permit Application for a development permit shall be made on fomls furnished by the floodplain E1amage-oontrof 9 FLOOD DAMAGE PREVENTION administrator and may include, but not be limited to, plans in triplicate 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. Specifically, the following information is required with application for the development permit: ( I) Elevation in relation to mean sea level of the proposed lowest floor (including basement) of all structures. (2) Elevation in relation to mean sea level to which any nonresidential structure will be floodproofed.
