(1) Above grade floor area: Any room that has a wall surface that extends more than three feet above grade, to be counted at 100%.
(2) Walkout basement floor area: Calculated as a percent of total basement floor area and includes all square footage enclosed by a 3 foot minimum exposed, exterior wall plate, see walkout basement definition.

Accessory structural elements located on the roof, such as solar panels, shall be subject to the total height requirements.
Landscape area.That portion of the front setback area that is required to contain landscape materials, and not impervious surfaces. Landscape materials shall include, but not be limited to, grass, ground covers, shrubs, vines, hedges, trees, and berms.
Lot.Land occupied or to be occupied by a building and its accessory building(s) and including such open spaces as are required under this article, and having its principal frontage upon a public street or officially approved place.

Non-occupied accessory building.A subordinate detached building used for a purpose customarily incidental to the main structure such as a private garage for automobile storage, tool house, greenhouse, home workshop, children's playhouse, storage house or garden shelter, but not involving the conduct of business or the use of such accessory structure as a separate domicile.
Occupied accessory building.A subordinate detached building used for a purpose customarily incidental to the main structure such as a guest house or quarters for servants employed on the premises, but not involving the conduct of business or the use of such accessory structure as a separate domicile.
Parapet.For a flat roof, the height to the top of the parapet from the natural or improved grade, whichever is the more restrictive.
Story.That portion of a building included between the surface of any floor and the surface of the floor next above it, or if there is no floor above it, then the space between such floor above the ceiling next above it.
Story, half.A story having an average height of not more than eight feet (8'), covering a floor area of not more than seventy-five percent (75%) of the area of the floor of the first story below.
Street.A public thoroughfare which affords primary means of access to abutting property and which is 16' or greater in width.
Structural alterations.Any change in the supporting member of a building, such as bearing walls, columns, beams or girders.
Vision triangle.The area created by connecting a line set back 30 feet from the curb or edge of paving, along the side property line and a line 30 feet from the curb or edge of paving, along the front property line. Vision triangles are used to maintain a clear line of sight at intersections.
Walkout basement.A basement that has an exit at-grade, although the majority of the basement remains below grade. Percentage of walkout basement floor area to be counted in the floor area ratio.

Step 1. Calculate the total wall plane area for each walkout basement wall. The walkout basement wall is the wall that measures more than 3 feet in vertical length from grade to the bottom of the first floor. See sketch #1. |
|
Step 2. Total the wall plane area for each walkout basement wall. |
Step 3. Calculate the total basement wall plane area. See sketch #2. |
|
Step 4. Divide Step 2. / Step 3. to find the percentage of the wall above grade. This is the percent walk-out wall plane area. |
Step 5. Multiply the percentage found in Step 4 by the total basement floor area. See sketch #3. The result will be the total square footage (walkout that should be included in your FAR calculation). |

Wall plate, front.A wall running parallel (or approximately so) to the front property line.
Wall plate, side.A wall running parallel (or approximately so) to a side property line.
Wall plate height.For a building with a flat or sloping roof, the height to the top horizontal framing member of a wall from finished floor or 18 inches above the natural or improved grade, whichever is more restrictive.
