(1) Density, gross. Gross density means the number of dwelling units permitted per gross acre of land and is determined by dividing the number of units by the total area of land within the boundaries of a parcel of land including existing streets, dedicated rights-of-way, tree protection zones, and open space set-asides, except as otherwise provided for in this ZDO. In the determination of the number of units to be permitted on a specific parcel of land, a fractional unit equal to or greater than one-half of a unit shall be rounded up to equal a full unit. A fractional unit less than one-half of a unit shall be rounded down, and not counted as a unit.
(2) Lot coverage. Lot coverage is a measure of intensity of a use of land that represents the portion of a site that is covered by impervious surfaces. This portion includes, but is not limited to areas covered by structures (including covered decks), parked structures, driveways, streets, sidewalks, and any other areas covered by an impervious surface material, including areas of outdoor storage and swimming pools.
(3) Floor area. Floor area means, except as may be otherwise indicated in relation to particular districts and uses, the sum of the gross horizontal areas of the several floors of a building measured from the exterior faces of the exterior walls or from the centerline of walls separating two buildings, excluding attic areas with a headroom of less than seven feet, unenclosed stairs or fire escapes, elevator structures, cooling towers, areas devoted to air conditioning, ventilating or heating or other building machinery and equipment, parking structures and basement space where the ceiling is not more than 48 inches above the general finished and graded level of the adjacent part of the lot.
