In portions of the city dating back to the Tacoma Streetcar Period (1888–1938), denser mixed-use business districts exist alongside single family homes. Twelve such districts have active, city-recognized business associations and hold "small town"-style parades and other festivals. The Proctor District, Tacoma, Old Town, Dome, 6th Avenue, Stadium, Lincoln Business District, and South Tacoma Business Districts are some of the more prominent of these and coordinate their efforts to redevelop urban villages through the Cross District Association of Tacoma. In newer portions of the city to the west and south, residential culs-de-sac, four-lane collector roads and indoor shopping centers are more commonplace.
