Sometimes, when communities are consolidated, the streets are renamed according to a uniform system. For example, when the community of Georgetown ceased to have even a nominal existence independent of Washington, D.C., the streets in Georgetown were renamed as an extension of Washington's street-naming convention. Also, when leaders of Arlington County, Virginia, asked the United States Post Office Department to place the entire county in the "Arlington, Virginia" postal area, the Post Office refused to do so until the county adopted a uniform addressing and street-naming system, which the county did in 1932.
