Annapolis, Md.

The Bordley Randall House is an 18th century home on a 11/4-acre lot, nestled in a city block adjacent to the State Circle in the historic center of Annapolis. The project included pouring a pervious concrete driveway for the historic home. The contractor's biggest challenge was the historic nature of the site, which meant meeting the historical society's strict aesthetic standards. Physical access was also a significant challenge, limited to a small alley leading to a narrow city street. Contractors protected the structural integrity of the full depth basements on either side of the alley with large steel plates distributing the weight of the trucks. After extensive research, the landscape architect recommended pervious concrete. The concrete contractor made suggestions that would streamline the work and incorporate architectural elements to satisfy permitting authorities. The final driveway design was 6 inches of pervious over 6 inches of #57 stone. The driveway apron and garage entrances were finished in colored concrete with an exposed aggregate. This project marks a turning point in the use of green construction in historic projects. Receiving permission to install a pervious concrete driveway in a historic city center was a feat that sets the standard for future projects.
