§ 155-11.20  CALCULATIONS.
   The following rules apply when calculating the required number of off-street parking and loading spaces required under this zoning ordinance.
   (A)   Multiple uses.  Unless otherwise expressly stated, lots occupied by more than one use must provide parking and loading in an amount equal to the total of the requirements for all uses that occupy the lot.
   (B)   Fractions.  When measurements of the number of required spaces result in a fractional number, any fraction of less than ½ is rounded down to the next lower whole number, and any fraction of ½ or more is rounded up to the next higher whole number.
   (C)   Area measurements.  All area-based (square footage) parking and loading standards must be computed on the basis of the total gross floor area devoted to such use, including accessory storage areas located within selling or working space such as counters, racks, or closets, and any floor area devoted to retailing activities, to the production or processing of goods, or to business or professional offices. However, for the purposes of determining off-street parking and loading space requirements the following areas are not counted as part of the gross floor area:
      (1)   Floor area devoted primarily to storage purposes (except as otherwise noted herein);
      (2)   Floor area devoted to off-street parking or loading facilities, including aisles, ramps and maneuvering space; or
      (3)   Mechanical or storage floor area other than area devoted to retailing activities, to the production of goods, or to business or professional offices.
   (D)   Seating or occupancy.  A seat is the space intended for a single individual; in places where patrons or spectators occupy benches, pews, or other similar seating arrangements, each 20 linear inches of such seating is counted as one seat. In places without fixed seating, each eight square feet of seating floor area is counted as one seat.
   (E)   Employees.  For the purpose of computing requirements based on employees, calculations must be based on the average number of persons working on any single shift.
   (F)   Unlisted uses.  Upon receiving a development application for a use not specifically listed in an off-street parking schedule, the Zoning Administrator is authorized to apply the off-street parking ratio specified for the listed use that is deemed most similar to the proposed use or establish a minimum off-street parking requirement for the proposed use in accordance with division (G) of this section.
   (G)   Establishment of other parking ratios.  The Zoning Administrator is authorized to establish required minimum off-street parking ratios for unlisted uses and in those instances where authority to establish a requirement is expressly granted. Such ratios may be established on the basis of a similar use/parking determination (as described in division (F) of this section), on parking data provided by the applicant or information otherwise available to the Zoning Administrator. Parking data and studies must include estimates of parking demand based on reliable data collected from comparable uses or on external data from credible research organizations (e.g., Institute of Transportation Engineers (ITE) or American Planning Association (APA)). Comparability will be determined by density, scale, bulk, area, type of activity and location. Parking studies must document the source of all data used to develop recommended requirements.
