a. Gateways. Figure 2-9 illustrates typical low volume gate areas. Discuss design for
gateways with the Provost Marshal and coordinate the requirements with the installation's
physical security plan. Design considerations for gate areas include:
(1) Provide adequate width for a gatehouse, traffic island, travel lane, and pullover lane.
(2) Provide adequate length on the access drive to accommodate stacking of vehicles
and to allow a transition zone into and out of the major traffic flow.
(3) Use curbs around traffic islands for vehicle control.
b. Drop-off Areas. Figure 2-10 illustrates a typical drop-off area. Design considerations
for drop-off areas include:
(1) Provide for accessibility as required by the Americans with Disabilities Act.
(2) Provide adequate width and length to accommodate the safe movement of vehicles
in and out of the flow of traffic.
(3) Maintain a minimum one- (1) percent grade across the area.
(4) Provide adequate area for stacking of vehicles.
c. Delivery and Service Zones. Delivery and service trucks need to access service doors
in buildings. Delivery may require dock facilities, which need to accommodate the necessary
maneuvering into and out of the dock. Figure 2-11 illustrates a typical loading area for a single
unit truck. Design considerations for delivery zones include:
(1) Separate service access drives from parking circulation because these functions are
incompatible. Service access that is required through a parking area goes straight to and
straight out of the service area as shown in figure 2-12.
(2) On a dead-end service drive, provide the necessary turning movements (See figures
2-11 and 2-12).
(3) Provide positive drainage away from the loading dock with a minimum gradient of
one (1.0) percent.
(4) Maintain a minimum one (1) percent grade or no more than three (3) percent grade
to the dock.
(5) Provide for visual screening with walls, fences or plant material.
d. Dumpsters. The design of garbage and trash removal areas is controlled by the size
and location of the dumpster and is coordinated with the local management company. Figure 2-
13 illustrates a typical dumpster pad layout. Design considerations for dumpster pads include:
(1) It is preferable for trucks to maintain a forward movement through the site. Design
for sanitation trucks to approach the pad in a straightforward manner, align with the dumpster,
reverse away from the pad and exit forward from the site.
(2) Locate dumpsters on concrete pads.
