Sec. 9-4.2403.  Computation of off-street parking spaces.
   (a)   Required off-street parking. All off-street parking spaces shall be computed as set forth in Section 9-4.2402 of this article, except as follows:
   (1)   When the application of said Section  9-4.2402 results in the requirement of a fractional parking space, any fraction up to one-half (1/2) may be disregarded, and any fraction equaling one-half (1/2) or more shall be construed as requiring one full parking space.
   (2)   When required parking computations are based on floor area, floor area devoted exclusively to parking shall have no off-street parking space or landscaping requirements.
   (b)   Mixed uses. In the case of mixed uses, the total requirements for off-street parking spaces shall be the sum of the requirements for the various uses. Off-street parking facilities for one use shall not be considered as providing parking facilities to any other use.
   The Commission, and in cases not otherwise involving permits which require approval by the Commission, the Community Development Director or a designee may approve alternating use of parking facilities where parties wish to cooperatively establish and operate parking facilities and where these uses generate parking demands primarily during hours when the remaining uses are not in operation (for example, if one use operates during the daytime or on weekends and the other use operates at other times).
   The burden of proof for a reduction in the total number of required parking spaces, however, shall remain with the applicant, and documentation shall be submitted to the decision-making body or officer substantiating the reasons for this requested parking reduction.  As a condition precedent to approving such alternating use, the decision-making body or officer shall require:
   (1)   That whenever alternative units of measurement are required for computing off-street parking requirements, that unit of measurement which provides the greatest number of off-street parking spaces shall control;
   (2)   The submission of satisfactory statements by the parties providing such facilities, and the parties such facilities are to serve, describing the nature of the uses and times when such uses operate so as to indicate the lack of conflict between them; and
   (3)   Such additional documents or agreements as the Commission and City Attorney may deem necessary in each particular case to assure provisions for and the maintenance of the required off-street parking spaces.
   (c)   Uses not specified.  The parking space requirements for uses not listed in Section 9-4.2402 of this article shall be defined by the Commission.  Such determination shall be based upon the requirements for the most comparable use specified in said Section 9-4.2402.
   (d)   Non-retail business and professional offices.
   (1)   New multi-tenant buildings. For the purpose of calculating parking space requirements for multi-tenant nonretail business, professional offices and other similar uses, approved under this Title after August 22, 1997, the square footage described in subsections (26) and (28) of Section 9-4.2402(c) shall mean only the building’s gross leasable floor area.  For the purpose of this calculation, “gross leasable floor area” shall mean the area within the total dimensions on each floor as measured from the outside walls, but excluding the interior common areas used for corridors, lobbies, stairways, common restrooms, elevator or mechanical shafts, and for any unmanned electrical or mechanical rooms.  In order to qualify as a “corridor” under this section, the area shall be a shared interior circulation hallway or common walkway feature more than five (5') feet in width with permanent walls on both sides that are constructed from floor to ceiling.
   (2)   Other buildings. For the purpose of calculating parking space requirements for any nonretail business, professional offices, other similar uses, and for multi-tenant offices approved under this title prior to August 22, 1997, which buildings are not covered by subsection (d)(1) of this section, the square footage described in subsections (26) and (28) of Section 9-4.2402(c) shall mean the building’s gross floor area.  For the purposes of this calculation “gross floor area” shall mean the entire area within the total dimensions on each floor as measured from the outside walls.
   (e)   Technology and life sciences use.
   (1)   For the purpose of calculating parking space requirements for the use, regardless if it is locating within new construction or in an existing building, no off-street parking spaces are required for floor area exclusively used and maintained for interior common areas such as corridors, lobbies, conference rooms, stairways, common restrooms, elevator or mechanical shafts and rooms, any unmanned electrical or mechanical rooms, and employee only kitchens, lunchrooms, exercise, or locker rooms. Any portion of the occupied space designated as Warehouse shall be parked according to Sec. 9-4.2402(d)(5) - Warehouses, exclusive of any sales activity.
