The provisions of this Section shall apply to parking facilities created after December 10, 2012, or for parking facilities enlarged by 50 or more spaces after December 10, 2012. For the purpose of determining required reservoir spaces, fractions equal to or greater than one-half resulting from the calculations in this Section shall be considered one reservoir space.

(a)        Attended parking facilities

Attended accessory parking facilities, public parking garages or public parking lots with more than 25 parking spaces shall provide the following amount of off-street reservoir space at the vehicular entrance:

(1)        for parking facilities with more than 25 parking spaces and up to 50 parking spaces: five percent of the total number of parking spaces;

(2)        for parking facilities with more than 50 parking spaces and up to 100 parking spaces: 10 percent of the total number of parking spaces;

(3)        for parking facilities with more than 100 parking spaces and up to 200 parking spaces: 10 parking spaces; and

(4)        for parking facilities with more than 200 parking spaces: five percent of the total number of parking spaces. However, such number of reservoir spaces need not exceed 50.

(b)        Automated parking facilities

For automated parking facilities, off-street reservoir space at the vehicle entrance shall be provided as set forth in paragraph (a) of this Section.

Each individual parking location where a driver is permitted to leave a vehicle for transfer to a mechanized automobile storage and retrieval unit shall constitute one reservoir space. Additional reservoir spaces may be located where drivers queue to access such locations for vehicle transfer.

In addition, the number of reservoir spaces required pursuant to paragraph (a) of this Section may be reduced where the Commissioner of Buildings determines that the operational characteristics of such automated parking facility warrant such a reduction.  

(c)        Self-parking facilities

For self-parking accessory parking facilities, public parking garages and public parking lots, where entering vehicles are required to stop at a mechanically operated barrier before entering the parking facility, such barrier shall be placed a minimum of 20 feet beyond the street line.
