# B. Parking Areas and Sidewalks
A mix of uses at a development site can allow for shared parking areas, reducing the total parking area. Municipalities require minimum parking areas, but seldom limit the total number of parking spaces. Table 1 shows recommendations for minimum parking space ratios for low impact design:

☐ Yes ☐ No Can the parking ratios be reduced?
☐ Yes ☐ No Are the parking requirements set as maximum or median rather than minimum requirements?
☐ Yes ☐ No Is the use of shared parking arrangements allowed to reduce the parking area?
☐ Yes ☐ No Are model shared parking agreements provided?
☐ Yes ☐ No Does the presence of mass transit allow for reduced parking ratios?
☐ Yes ☐ No Is a minimum stall width of 9 feet allowed?
☐ Yes ☐ No Is a minimum stall length of 18 feet allowed?
