<br />Land Area Measurement Definitions
<br />(See Lot Line, Lot Line Front, Lot Line Rear, Lot Line Side, Open Side, Open Space Front, Open Space
<br />Rear)
<br />Land-Disturbing Activity
<br />Any use of the land that results in a change in the natural cover or topography that may cause or
<br />contribute to sedimentation.
<br />Landfill
<br />A site within which is deposited solid waste material, including trash, construction debris, stumps,
<br />branches and limbs, garbage and industrial waste.
<br />Landfill, Discharging
<br />A landfill facility with liners, monitoring equipment and other measures to detect and/or prevent leachate
<br />from entering the environment and in which the leachate is treated on site and discharged to a receiving
<br />stream. Discharging landfills require a National Pollution System (NPDES) Permit from the North
<br />Carolina Division of Water Quality.
<br />Land Use Intensity Definitions
<br />(See Non-residential Land Area, Non-residential Floor Area, Residential Floor Area, Floor Area Ratio,
<br />Open Space, Open Space Ratio, Livability Space, Livability Space Ratio, Floor Area Ratio, Open Space,
<br />Open Space Ratio, Recreation Space, Recreation Space Ratio, Pedestrian/Landscaped Space,
<br />Pedestrian/Landscaped Space Ratio.)
<br />Land Use Permit
<br />A zoning permit, subdivision approval, building permit, site plan, special use permit, or conditional use
<br />permit.
<br />Land Use Plan
<br />A set of documents and maps that categorize existing patterns of land development and set guidelines for
<br />the desirable intensity, density, quantity, type, location and timing of future development based upon the
<br />goals and policies set forth in the Plan. The Land Use Plan can be found in the Land Use Element of the
<br />Comprehensive Plan.
<br />Length of Wall
<br />The horizontal distance from corner to corner. Where walls in continuous general frontage (as in the case
<br />of attached dwellings) are off-set by angles or setbacks of six feet or more, the length of each segment so
<br />set off shall be measured separately in establishing pertinent yard depth. Length of the wall of a circular
<br />building shall be construed as the diameter of the building.
<br />
<br />Letter of Map Change (LOMC)
<br />An official determination issued by FEMA that amends or revises an effective Flood Insurance Rate Map
<br />or Flood Insurance Study. Letters of Map Change include:
<br />
<br />(a) Letter of Map Amendment (LOMA): An official amendment, by letter, to an effective National
<br />Flood Insurance Program map. A LOMA is based on technical data showing that a property
<br />had been inadvertently mapped as being in the floodplain, but is actually on natural high
<br />ground above the base flood elevation. A LOMA amends the current effective Flood
<br />Insurance Rate Map and establishes that a specific property, portion of a property, or
<br />structure is not located in a special flood hazard area.
<br />(b) Letter of Map Revision (LOMR): A revision based on technical data that may show changes
<br />to flood zones, flood elevations, special flood hazard area boundaries and floodway
<br />delineations, and other planimetric features.
<br />(c) Letter of Map Revision Based on Fill (LOMR-F): A determination that a structure or parcel of
<br />land has been elevated by fill above the BFE and is, therefore, no longer located within the
<br />special flood hazard area. In order to qualify for this determination, the fill must have been
<br />permitted and placed in accordance with the community’s floodplain management
