The SCA area runs from 395 to Arlington Mill Drive to Windgate 1 across Walter Reed Drive and up to the intersection with Rt.7. It includes the residents, commercial property owners, and businesses in the Village at Shirlington. It also includes eight nearby homeowners’ associations that have never been in any civic association: The Arlington, Courtbridge I, Windgate Village of Arlington I, Windgate Village of Arlington II and Windgate Village of Arlington III, The Heatherlea, and Shirlington Village Condominiums. Residents of the three apartment complexes within this area are also included — the Io Piazza, the Windsor, and the Delancey.

Last but not least, the SCA area covers some important Arlington county institutions — The Arlington County Trades Center, the Shirlington Public Library, the Shirlington Bus Station, and the Animal Welfare League, all county-owned properties, and of course both the Signature Theater and the Energy Club.
