The channel of a river or other riverine watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. [ Also defined in FBC, B, Section 1612. 2.] Floodway encroachment analysis. An engineering analysis of the impact that a proposed encroachment into a floodway is expected to have on the floodway boundaries and base flood elevations; the evaluation shall be prepared by a qualified Florida licensed engineer using standard engineering methods and models. Florida Building Code. The family of codes adopted by the Florida Building Commission, including: Florida Building Code, Building; Florida Building Code, Residential; Florida Building Code, Existing Building; Florida Building Code, Mechanical; Florida Building Code, Plumbing; Florida Building Code, Fuel Gas. Functionally dependent use.

Highest adjacent grade. The highest natural elevation of the ground surface prior to construction next to the proposed walls or foundation of a structure. Historic structure. Any structure that is determined eligible for the exception to the flood hazard area requirements of the Florida Building Code, Existing Building, Chapter 11 Historic Buildings. Letter of May Change ( LOMC). An official determination issued by FEMA that amends or revises an effective Flood Insurance Rate Map or Flood Insurance Study. Letters of Map Change include: Letter of Map Amendment ( LOMA): An amendment based on technical data showing that a property was incorrectly included in a designated special flood 25  hazard area. A LOMA amends the current effective Flood Insurance Rate Map and establishes that a specific property, portion of a property, or structure is not located in a special flood hazard area. Letter of Map Revision ( LOMR): A revision based on technical data that may show changes to flood zones, flood elevations, special flood hazard area boundaries and floodway delineations, and other planimetric features. Letter of Map Revision Based on Fill ( LOMR -F): A determination that a structure or parcel of land has been elevated by fill above the base flood elevation and is, therefore, no longer located within the special flood hazard area. In order to qualify for this determination, the fill must have been permitted and placed in accordance with the community' s floodplain management regulations. Conditional Letter of Map Revision ( CLOMR): A formal review and comment as to whether a proposed flood protection project or other project complies with the minimum NFIP requirements for such projects with respect to delineation of special flood hazard areas. A CLOMR does not revise the effective Flood Insurance Rate Map or Flood Insurance Study; upon submission and approval of certified as -built documentation, a Letter of Map Revision may be issued by FEMA to revise the effective FIRM.

Designed primarily for transportation of persons and has a capacity of more than 12 persons; or 3. Available with special features enabling off -street or off -highway operation and use. Lowest Floor. The floor of the lowest enclosed area of a building or structure, including basement, but excluding any unfinished or flood -resistant enclosure, usable solely for vehicle parking, building access or limited storage provided that such enclosure is not built so as to render the structure in violation of the Florida Building Code or ASCE 24. Also defined in FBC, B, Section 1612. 2.1 Manufactured home. A structure, transportable in one or more sections, which is eight 8) feet or more in width and greater than four hundred ( 400) square feet, and which is built on a permanent, integral chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term " manufactured home" does not include a " recreational vehicle" or " park trailer." [ Also defined in 15C- 1. O101, F.A.C.] Manufactured home park or subdivision. A parcel ( or contiguous parcels) of land 26 divided into two or more manufactured home lots for rent or sale Market value.

Watercourse. A river, creek, stream, channel or other topographic feature in, on, through, or over which water flows at least periodically. SECTION 3. FISCAL IMPACT STATEMENT. In terms of design, plan application review, construction and inspection of buildings and structures, the cost impact as an overall average is negligible in regard to the local technical amendments because all development has been subject to the requirements of 3J the local floodplain management ordinance adopted for participation in the National Flood Insurance Program. In terms of lower potential for flood damage, there will be continued savings and benefits to consumers. SECTION 4. APPLICABILITY. For the purposes of jurisdictional applicability, this ordinance shall apply in the City of Fort Walton Beach. This ordinance shall apply to all applications for development, including building permit applications and subdivision proposals, submitted on or after May 1, 2012. SECTION 5.
