The term does not include long-term storage, manufacture, sales, or service facilities.
" Future Conditions Flood Hazard Area." Also known as area of future conditions flood hazard, the land area that would be inundated by flood based on future conditions hydrology. Any areas outside the flood hazard area identified by FEMA and designated as Future Conditions Flood Hazard Area on FEMA's Flood Insurance Rate Map shall also be considered special flood hazard areas.
" Highest Adjacent Grade." The highest natural elevation of the ground surface, prior to construction, next to the proposed walls of a structure.
" Lowest Floor." The lowest floor of the lowest enclosed area (including basement). An unfinished flood resistant enclosure, usable solely for parking of vehicles, buildings access or storage in an area other in an area other than a basement area is not considered a building's lowest floor, provided that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of these regulations.
" Mangrove Stand." An assemblage of mangrove trees which is mostly low trees noted for a copious development of in development of interlacing more of the following species: black mangrove (Avicenna Nitida); red mangrove (Rhizosphere mangle); white mangrove (L anguncularia racemose); and buttonwood (Conocarpus Erecta).
" Manufactured Home." A building or structure transportable in one or more sections, which is built on permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. Also includes recreational vehicles or travel trailers, placed on a site for greater than 180 consecutive days.
" Mean High Tide." The average height of the sea for all stages of high tide.
" Mean Sea Level." The average height of the sea for all stages of the tide. For purposes of these regulations, the term is synonymous with National Geodetic Vertical Datum (NGVD). It is used as a reference for establishing varying elevations within the floodplain.
" National Geodetic Vertical Datum (NGVD)." A vertical control, as corrected in 1929, used as a reference for establishing varying elevations within the floodplain.

" Substantial Improvement." Any repairs, reconstruction, alteration, or improvements to a structure, the cost of which equals or exceeds fifty percent (50%) of the value of the structure either (1) before the improvement or repair is started or (2) if the structure has been damaged and is being restored, before the damage occurred. For the purpose of this definition "substantial improvement" is considered to occur when the first alteration affects the external dimension of the structure. The term does not, however, include either (1) any project for improvement of a structure to comply with existing state health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions, or (2) any alteration of a structure listed on National Register of Historic Places or which are considered eligible for nomination of the National Register by the State Director of the Department of Archives and History or which are listed on the State Inventory of Historic Places.
