17-10-0400  Calculation rules.
   The following rules apply when calculating off-street parking requirements.
   17-10-0401 Multiple Uses.
      17-10-0401-A Unless otherwise approved, lots containing more than one principal use must provide parking in an amount equal to the total of the requirements for all principal uses. (See the shared and cooperative parking provisions of Sec. 17-10-0600 and Sec. 17-10-0800 for possible exceptions)
      17-10-0401-B When two or more principal uses are located on a single lot and the applicable parking ratio for such uses exempts a certain portion of the floor area (e.g., the first 4,000 or 10,000 square feet), only one such floor area exemption may be taken.
      17-10-0401-C No parking is required for accessory uses unless otherwise expressly stated.
   17-10-0402 Fractions. When measurements of the number of required spaces result in a fractional number, any fractional result of 0.5 or more must be rounded up to the next consecutive whole number. Any fractional result of less than 0.5 may be rounded down to the previous consecutive whole number. For example, if a minimum ratio of 2 spaces per 1,000 square feet is applied to a use with 1,900 square feet of floor area, the result (3.8) must be rounded up to 4 spaces.
   17-10-0403 Area Measurements.
      17-10-0403-A Unless otherwise expressly stated, all area-based (square feet) parking standards must be computed on the basis of gross floor area, which is to be measured as the sum of the gross horizontal area devoted to such use, including accessory storage areas located within sales or working spaces, such as counters, racks, or closets and any basement floor area devoted to retailing activities, to the production or processing of goods, or to business or professional offices. Except as noted in the preceding sentence, “floor area” for purposes of calculating off- street parking requirements does not include: floor area devoted primarily to storage purposes; floor area devoted to off-street parking or loading facilities, including aisles, ramps, and maneuvering space; or basement floor area.
      17-10-0403-B For outdoor areas, calculations will be based on the portion of the lot actually being used for the specified purpose.
      17-10-0403-C When open land is used for manufacturing, storage, or other operations in a manner similar to indoor operations, such open use of land must be added to floor space in determining the number of off-street parking spaces required
   17-10-0404 Occupancy- or Capacity-Based Standards. For the purpose of calculating parking requirements based on employees, students, or occupants, calculations are to be based on the greatest number of persons working on any single shift, the maximum enrollment or the maximum fire-rated capacity, whichever is applicable and whichever results in the greater number of spaces.
   17-10-0405 Bench Seating. When seating consists of benches, pews or other similar seating facilities, each 20 linear inches of seating space counts as 1 seat.
   17-10-0406 Unlisted Uses. Upon receiving a permit or development application for a use not specifically addressed, the Zoning Administrator is authorized to apply the off-street parking standard specified for the use that the Zoning Administrator deems most similar to the proposed use or require the applicant to submit a parking study or other evidence that will help Zoning Administrator determine the appropriate parking ratio to be applied.
   17-10-0407 Public Places of Amusement. There is no special parking requirement for uses that require a public place of amusement (PPA) license. Parking requirements are to be determined solely in accordance with the off-street parking schedules of Sec. 17-10-0200.
