Air Force Corporate Standards
To define and maintain visual continuity for site development and facilities on Air Force installations it may be necessary for a base to create or designate “Facility Districts.” A Facility District is a unique visual zone with a distinguishable architectural setting. A District is further defined as a geographic area with readily identifiable boundaries and a consistent visual character—similar form, scale, palette of materials, etc.—throughout that area. Examples of Facility Districts include historical areas, flightlines, housing areas, or medical campuses.
Facility Districts shall fully comply with the base’s Installation Development Plan (IDP) and Area Development Plans (ADPs). Sites and buildings within a Facility District shall comply with Facility Group designations as defined under the Facility Hierarchy topic of this AFCFS and the base’s Installation Facilities Standards (IFS).
