Geography
Part of a broader area colloquially named Chevy Chase, the CDP is encompasses 2.5 square miles (6.3 km), all land.
The CDP is bounded on its northern and eastern sides by Rock Creek, a tributary of the Potomac River, and bisected by the Rock Creek tributary of Coquelin Run. The latter stream was dammed in 1892 to form Chevy Chase Lake and support an eponymous trolley park. The lake was drained in the 1930s but the adjacent neighborhood retains the name.
