maneuver within the stream of traffic. Both levels of service describe a level
of restricted mobility with the addition of traffic on the roadways.
On Irish Hill Drive, the GRPC projected that traffic volumes will increase on
White Avenue and Irish Hill Drive as shown in Table 5‐9; such projections
were not provided for Forrest Avenue or Meadows Drive. The GRPC
provided the following projections for Average Daily Traffic (ADT):

Comprehensive Plan
The table indicates that White Avenue and Irish Hill Drive between Veterans
Avenue and Iberville Drive, located towards the southwest end of the
installation, are not projected to meet their capacity for roadway traffic.
Although this is the case, both roadways are projected to nearly double in
daily traffic by 2030, indicating that traffic mitigation will be needed if the
upward trend in growth continues. Irish Hill Drive between White Avenue
and Porter Avenue, located towards the east end of the installation, is
projected to increase beyond its roadway capacity by 2030. This indicates a
need for roadway improvements on Irish Hill Drive.
and Irish Hill Avenue if vehicles use U.S. 90 or I‐110 to access Division Street.
With the development of the Division Street Gate, White Avenue Gate will
become a secondary access into the installation. As a result of the Division
Street Gate, there is potential for Meadows Drive Gate to be closed with the
addition of Division Street Gate. This would reduce traffic on Meadows
Drive, but would likely not reduce traffic on Forrest Avenue since the
collector will provide access to Division Street Gate. Thus, traffic in this
residential neighborhood may continue to exist.
Currently, Division Street is classified as a minor arterial roadway. With
improvements to the road, it is envisioned that Division Street will have the
capacity to queue traffic into the installation without creating further
backups on other roads. The development of Division Street Gate is further
discussed in Issue IE‐1.
The DoD provides specific standards associated with the proper queuing and
stacking of vehicles, which have been established to allow for this activity to
take place largely within the installation property. The United Facilities
Criteria (UFC) 4‐022‐01, Security Engineering: Entry Control Facilities /
Access Control Points, provides design and construction standards for entry
