CHAPTER 3 SITE ENGINEERING
VEHICULAR AND PEDESTRIAN CIRCULATION
Vehicular and pedestrian circulation systems should provide convenient and safe
access and circulation within the housing area, and to adjacent service areas.
Roads and Streets.
Street systems should minimize through traffic in housing areas. Roads and streets
must be adequate to accommodate occupant traffic, service vehicles (including
maintenance, trash removal, buses, moving vans, and fire fighting equipment), and
snow removal equipment where applicable. The development of improved vehicular
circulation systems is one of the best ways to strengthen identity of neighborhoods.
Although the street system should provide safe, convenient access to housing units to
and from the neighborhood, it must not play a dominant role with respect to overall
housing area environment. The street system should defer to, and be supportive of,
pedestrian-oriented systems and should be designed with the following hierarchy of
A residential street should have a minimum width of 6.1 m (20 ft), with 3.0 m (10 ft) wide
travel lanes. A residential street carries low volumes of traffic and functions as access
to each housing cluster.
Collector streets should have a minimum width of 7.3 m (24 ft), with 3.7 m (12 ft) wide
travel lanes. Collector streets handle traffic from a group of clusters and respective
residential streets. Do not locate housing units on collector streets.
Arterial streets should be a minimum of 9.1 m (30 ft) wide, with 3.7 m (12 ft) wide travel
lanes, and 0.9 m (3 ft) wide shoulders on each side. Arterial streets are major streets
that carry traffic from collector streets and provide access to other areas of the
Installation. Do not locate housing units on arterial streets.
Curb, Gutter, and Sidewalk.
Curbs and gutters should be provided on all new streets. Sidewalks are required on at
least one side of each street (see paragraph 3-1.5 for additional information on
sidewalks). A "greenbelt" space should separate sidewalk and curb for pedestrian
