(sometimes shown on Flood Boundary and Floodway Maps), and the water surface elevations of <br />the base flood. <br />(p) Flood Protection Elevation. <br />The Flood Protection Elevation, or FPE, is the base flood elevation plus1a feet_of freeboard. ;.- - Formatted: Hi9nii9nt <br />--?? =?.:: -? ?--._?-- ------__ --_ 1--?-- <br />In areas where no base flood elevations exist from any authoritative source, the flood protection , Formatted: Hi9nn9nt <br />elevation can be historical flood elevations, or base flood elevations determined and/or approved <br />by the floodplain administrator. <br />(q) Floodwav. <br />A floodway is the channel of a river or other watercourse and the adjacent land areas that have <br />been reserved in order to pass the base flood discharge. A floodway is typically determined <br />through a hydraulic and hydrologic engineering analysis such that the cumulative increase in the <br />water surface elevation of the base flood discharge is no more than a designated height. In no <br />case shall the designated height be more than one foot at any point within the community. <br />The floodway is an extremely hazardous area, and is usually characterized by any of the <br />following: Moderate to high velocity flood waters, high potential for debris and projectile <br />impacts, and moderate to high erosion forces. <br />(?•) Freeboard. <br />A factor of safety usually expressed in feet above a flood level for the purposes of floodplain <br />management. Freeboard tends to compensate for the many unknown factors that could contribute <br />to flood heights greater than the height calculated for a selected size flood and floodway <br />conditions, such as wave action, obstructed bridge openings, debris and ice jams, and the <br />hydrologic effect of urbanization in a watershed. <br />? (s) I3istoric structure. <br />Any structure that is: <br />1. Listed individually in the National Register of Historic Places (a listing maintained by <br />the U.S. Department of Interior) or preliminarily determined by the Secretary of the <br />Interior as meeting the requirements for individual listings on the National Register; <br />2. Certified or preliminarily determined by the Secretary of the Interior as contributing <br />to the historical significance of a registered historic district or a district preliminarily <br />determined by the Secretary to qualify as a registered historic district; or <br />3. Individually listed on the State of Ohio's inventory of historic places maintained by <br />the Ohio Historic Preservation Office. <br />4. Individually listed on the inventory of historic places maintained by Mavlield <br />VillaacFC=E?}A?1L41414A-(T=l'-N-A-W;}'s historic preservation program, which program is <br />certified by the Ohio Historic Preservation Office. <br />I(t) Hvdrologic and hydraulic enEineering analysis. <br />An analysis performed by a professional engineer, registered in the State of Ohio, in accordance <br />with standard engineering practices as accepted by FEMA, used to determine flood elevations <br />and/or floodway boundaries.
