Hierarchy of Intersections

  1. Provide a hierarchy of intersections to include arterial, arterial-collector, collector, collector-local and local following UFC 3-201-01 and its industry references.
  2. Passive systems such as traffic circles are preferred to active systems such as signalized intersections. Aggressively pursue passive systems to lower initial costs, lessen ongoing maintenance requirements and reduce energy use.
  3. Use a level of visual quality for an intersection equal to the quality found in the related streetscape, which corresponds to the adjacent Facility Group number.

Establish and illustrate a hierarchy of street types on an installation through Street Envelope Standards. Address and provide dimensions as applicable for vehicular traffic-lanes, curb radii, sight lines, bike lanes, medians, pedestrian buffers, force protection features, sidewalks, crosswalks, tree planting areas, site furnishings, signs, lighting, utilities, on-street parking, and paving. Provide standards for arterials, collectors, local streets, and special routes such as those designated to accommodate distinguished visitors. Include this information in the base’s Installation Facilities Standards (IFS).

Coordinate Street Envelope Standards with the Installation Development Plan and its related component plans. Establish an appropriate level of quality that corresponds to the adjacent Facility Group number.


Comply with guidance for water conservation, energy efficiency and sustainable design under UFC 1-200-02. Develop bioswales as constituent parts of street envelopes to enhance water quality and support the overall stormwater system.
