Why it's listed

Scott Field, now Scott Air Force Base, lies about 25 miles east of St. Louis in St. Clair County, Illinois. The historic district preserves the original 1917 base layout and the eastern expansion built between 1937 and 1940. The base was set on level, well-drained land beside a railroad line and was organized on a north-south and east-west grid, with administrative offices, barracks, an industrial area and airfield. Officers' housing was built in the Colonial Housing and Georgian Housing areas, mostly as two-story brick duplexes and triplexes based on standardized Army plans. Administrative buildings such as the Post Headquarters use Neo-Classical and Colonial Revival detailing, including Doric porticos. Service buildings, garages, Hangar No. 1 and recreational facilities complete the group. Because postwar growth occurred mainly west of the original base, the 1917-1946 layout remains intact, with mature oak and maple trees lining the streets. The district contains 107 contributing and 12 noncontributing resources.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
