Morrisville Unified Development Ordinance - February 2021.2

Article 11: Interpretation and Definitions Section 11.5. Terms and Uses Defined 11.4.3. Illuminated Signs

F REEBOARD The height added to the Base Flood Elevation (BFE) or the Future Conditions Flood Elevation to account for the many unknown factors that could contribute to flood heights greater that the height calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effect of urbanization on the watershed. The Base Flood Elevation plus the freeboard establishes the “Regulatory Flood Protection Elevation.” F REEWAY A specialized accessway that functions solely to channel intercity vehicular traffic to and through the Town and to connect major thoroughfares. It consists of a multi-lane divided highway that handles high traffic volumes at very high travel speeds, and limits access to grade-separated interchanges. F RONT OR F RONTAGE The “front” or “frontage” is that side of a lot abutting on a street or way, and ordinarily regarded as the front of the lot, but it shall not be considered as the ordinary side line of a corner lot. F RONTAGE R OAD A road that is parallel to any freeway or expressway and provides access to adjacent land. F ULL C UTOFF W ALL P ACK A type of light fixture typically flush-mounted on a vertical wall surface that emits no light above the horizontal plane of the fixture. F UNCTIONALLY D EPENDENT F ACILITY A facility that cannot be used for its intended purpose unless it is located in close proximity to water, such as a docking or port facility necessary for the loading and unloading of cargo or passengers, shipbuilding, or ship repair. The term does not include long-term storage, manufacture, sales, or service facilities. F UNERAL H OME An establishment engaged in undertaking services such as preparing the dead for burial, and arranging and managing funerals. F UTURE C ONDITIONS F LOOD The flood having a one percent chance of being equaled or exceeded in any given year based on future conditions hydrology. F UTURE C ONDITIONS F LOOD E LEVATION A determination of the water surface elevations of the one percent annual chance flood based on future conditions hydrology as published in the Flood Insurance Study. This elevation, when combined with the freeboard, establishes the “Regulatory Flood Protection Elevation” in Future Conditions Flood Hazard Areas. F ULL C UTOFF A fixture light distribution where no light intensity is emitted at or above a horizontal plane drawn through the bottom of the fixture and no more than ten percent of the lamp’s light intensity is emitted at or above an angle ten degrees below that horizontal plane, at all lateral angles around the fixture.
