Full Cutoff Fixture An outdoor light fixture shielded or constructed in such a manner that it emits no light above the horizontal plane of the fixture. Future Conditions Flood The flood having a 1 percent chance of being equaled or exceeded in any given year based on future conditions hydrology. Future Conditions Flood Elevation A determination of the water surface elevations of the 1 percent annual chance flood based on future conditions hydrology as published in the flood insurance study. This elevation, when combined with 2 additional vertical feet, establishes the regulatory flood protection elevation in future conditions flood hazard areas. Future Conditions Flood Hazard Area The land area that would be inundated by the 1 percent annual chance flood based on future conditions hydrology as determined in this UDO. Future Conditions Hydrology The flood discharges associated with projected land use conditions based on Raleigh’s zoning maps or the Comprehensive Plan’s Future Land Use Map or both and without consideration of projected future construction of flood detention structures or projected future hydraulic modifications within a stream or other waterway such as bridge and culvert construction, fill and excavation.

Governmental Entity Any department, commission, agency or other instrument of the Federal, State, County or municipal government. Green Stormwater Infrastructure (GSI) Any of a number of practices that, used individually or collectively, contribute to managing, treating, and reducing stormwater runoff from a development or redevelopment site, as close as possible to the runoff's source, by preserving natural landscape features (such as vegetation, soils, hydrology, and natural processes) and/or by mimicking natural processes through installation and maintenance of structurally engineered devices (such as bioretention cells, bioswales, permeable paving/pavers, green roofs, stormwater street trees, and cisterns). In addition to contributing to stormwater management, GSI practices can enhance site aesthetics, improve air quality, reduce urban heat island impacts, provide shading, create wildlife habitat, reduce energy consumption, reduce infrastructure costs, and increase property values. Gross Floor Area The sum in square feet of the gross horizontal area of all floors of a building measured from the exterior walls or from the centerline when 2 buildings or units abut. Gross floor area includes basement floor area when more than 50% of the basement height is above the established curb level or above the finished lot grade level where the curb level has not been established. Elevator shafts, stairwells, floor space used for mechanical equipment, attics, balconies and mezzanines, enclosed porches and floor area devoted to accessory uses are included in the calculation of gross floor area. However, the following shall not be included: any space devoted exclusively to on-site parking; outdoor loading, display, storage, utility service areas; and/or uninhabited enclosed space on tops of roofs; or attic space having head room of less than 7'-10".
