§ 3312.09. Aisle.

An aisle is that portion of the circulation area within a parking lot, excluding the driveway, which provides accessibility to parking, stacking or loading spaces.

An aisle to serve adjacent loading spaces shall have a minimum width of 15 feet. No part of the loading space may be included in this calculation.

The minimum width permissible for an aisle to serve adjacent parking spaces shall depend on the smallest angle of parking as measured between the centerline of the aisle and the centerline of the adjacent parking space as illustrated in Figure 1 and as set out in the table marked Figure 2:
