The Arlington County Courthouse is located at 2100 Clarendon Boulevard, Arlington VA 22201; phone: 703-228-3120.
At 26 square miles, Arlington is the smallest self-governing county in the U.S.
While technically, a county, we list Arlington neighborhoods under the pseudo-municipality (Arlington) to fit the hierarchy of Living Places which is: County-Municipality-Neighborhood/District.
There are a number of un-incorporated neighborhoods within Arlington that are commonly referred to by name as if they were distinct towns. For over 30 years, the government has pursed a development strategy of concentrating much of its new development near transit facilities, such as Metrorail stations and the high-volume bus lines of Columbia Pike. Within the transit areas, the government has a policy of encouraging mixed-use and pedestrian- and transit-oriented development. These urban villages are listed as municipalities to keep the logical structure of County-Municipality-Neighborhood of Living Places' original design.
