About the area:
Dunwoody lies at the northern tip of DeKalb County, bounded by the Fulton County line on the north and west, Interstate 285 on the south, Peachtree Industrial Boulevard on the southeast, and Gwinnett County on the northeast. Officially, the city limit extends only to the DeKalb County line in the north. However, many residents of the narrow panhandle of Sandy Springs (the strip of Fulton between the Dekalb County line in the south up to the Chattahoochee River in the north) consider themselves a part of Dunwoody. To this end, the Dunwoody name is present in the panhandle's many apartment complexes, roads and shopping centers (such as the Dunwoody Place Shopping Center). Although Sandy Springs claimed its right to self-determination in its own political battle to incorporate, once Sandy Springs became a city in late 2005, it removed "Dunwoody" street sign toppers in the panhandle area. This narrow strip was originally part of DeKalb, but was then ceded to Milton County, which later merged into Fulton.
Perimeter Mall and approximately 40 percent of the Perimeter Community Improvement District, is a self-taxing district of shopping and office buildings (including several high-rises), are both located in Dunwoody.
