(3) Provide positive drainage away from the pad.
(4) Screen the pad with fences, walls or plant material.
e. Drive-in Facilities. Drive-in facilities, such as banks and fast-food restaurants, require
careful and clear establishment of traffic patterns and a continuous traffic flow. The standard
configuration for a single- or double-service position facility does not lend itself to a two-lane
approach and departure design. It usually relies on some form of loop system. Average stacking
distance is recommended as 55m (180 ft). Stacking space is determined by subtracting the
number served (serving time averages 2-3 minutes per customer) from the expected arrivals per
15-minute period (4-14 minutes is the average) and multiplying the difference times 6.0m (20 ft).
Recommended parking for drive-in facilities is 17.5 spaces per 93.0 sq. m (1,000 sq. ft) of
building area. Design considerations for drive-in facilities include:
(1) Maintain traffic lanes into and out of the drive-in windows while working with other
on-site vehicular traffic flow including parking.
(2) Minimize interference with pedestrian traffic flow.
(3) Provide the recommended average stacking distance in the drive-through lanes.
(4) Provide the recommended average stacking distance on-site to prevent traffic safety
conflicts with access roads.
(5) Use curb and planting islands for vehicle control.
(6) Provide adequate pavement markings.
f. Motorcycle Parking. Figure 2-14 illustrates a typical motorcycle parking area. Design
considerations for motorcycle parking include:
(1) Locate parking close to building entrances.
(2) Locate parking in parking lot corners.
(3) Place parking on a concrete pad.
(4) Provide signage and pavement markings.
g. Emergency Vehicle Access. Provide for the access, circulation and parking of
emergency vehicle access as required in the design requirements. These vehicles are to be
provided with dedicated access drives.
2-7. MITIGATING VEHICULAR IMPACT. Circulation and parking areas consume large land
areas with paved surfaces, explore all possible methods of mitigating the impact of circulation
and parking areas.
a. Buffers. A recommended minimum 6m (20 ft) wide buffer strip should be provided to
separate parking areas from adjacent streets. In areas of limited space provide a minimum
distance of 2.4m (8 ft).
b. Topography. Design parking areas to conform to existing topography and balance the
cut and fill. Where slopes are steep, provide more than one level of parking.
