All new or altered parking lots shall conform to the parking space stall width, length, and aisle width, as set out in Table I and Exhibit 1.
TABLE 1
Dimensions | 45o Angle | 60o Angle | 75o Angle | 90o Angle |
A. Stall Depth to Wall | 17' | 18.5' | 19' | 18' |
B. Stall Depth Parallel to Vehicle | 18' | 18' | 18' | 18' |
C. Aisle Width | 12' | 18' | 22' | 25' |
D. Stall Depth to Interlock | 15' | 17' | 18' | 18' |
E. Stall Depth Reduction Due to Interlock | 2' | 1.5' | 1' | 0' |
F. Stall Width Parallel to Aisle 1 | 12.7' | 10.4' | 9.3' | 9' |
G. Stall Width Perpendicular to Vehicle | 9' | 9' | 9' | 9' |
H. Module Width Wall to Wall | 45' | 54' | 60' | 61' |
I. Module Width Interlock to Interlock | 42' | 51' | 52' | 51' |
Exceptions to TABLE I:
(a) For bumper overhang deduct one and one-half (1-1/2) feet from stall depth to wall or three (3) feet from wall to wall for forty-five (45) degrees and sixty (60) degree parking. The equivalent dimensions for seventy-five (75) degree and ninety (90) degree parking are two (2) feet and four (4) feet respectively.
(b) The Americans with Disabilities Act Accessibility Guidelines (ADAAG) requires all new facilities to meet ADAAG requirements. Approval of a plan by City officials shall not provide a defense of a failure to meet ADA requirements. For most uses, spaces designed as accessible parking spaces must be provided in each lot or structure and distributed to serve all accessible entrances and must in each case be located on the shortest possible route to the accessible entrance.
(1) ADAAG requirements for accessibility of parking spaces will require most uses to provide the following minimum number of accessible spaces:
Total Parking Spaces in Lot | Minimum Number of Accessible Spaces |
1 to 100 | 1 space, plus 1 space for each additional 25 spaces |
101 to 200 | 5 spaces, plus 1 space for each additional 50 spaces over 100 |
201 to 500 | 7 spaces, plus 1 space for each additional 100 spaces over 200 |
501 to 1,000 | 2% of total number of spaces provided (round fractions down) |
1,001 and over | 20, plus 1 for each additional 100 spaces (or portion thereof) over 1,000 |
Outpatient medical units and treatment facilities | 10% of the total number of spaces provided (round fractions down) |
Units or facilities that specialize in treatments or services for persons with mobility impairments | 20% of the total number of spaces provided (round fractions down) |
(2) Accessible spaces are required to be eight (8) feet wide, with an adjacent access aisle that is five (5) feet wide (one access aisle may be shared by two spaces). The access aisle portion must be demarcated with paint striping (that is, a single 13-foot wide space is not acceptable) and signed with an ADA sign symbol. One (1) in every eight (8) accessible spaces is to have an access aisle eight (8) feet wide (rather than 5 feet wide) and shall be additionally signed “van accessible.”
(c) Where natural and/or man-made obstacles, obstructions, or other features such as but not limited to landscaping, support columns, or grade difference exist, the City may approve a reduction in stall width, stall length, and/or module width as part of the site plan review process. In all instances where a reduction is requested, attention to emergency vehicle access shall be considered and incorporated into the parking lot design.
