Harpers Square Cluster Association (HSCA) is a 50-townhouse community quietly nestled on the south side of Reston.  The cluster was built in the early 1980s (1981-1982) and is surrounded by woods and babbling brooks.

It is conveniently located close to the Dulles Toll Road and the Wiehle Reston East Silver Line Metro stop.

The South Lakes Shopping Center and the Lake Thoreau pool are within walking distance of the cluster.  Lake Audubon and the Lake Audubon pool are two miles away.
