When landscape architect Blake Dunlevy of D.A. Dunlevy first encountered a client’s backyard in Kensington’s historic district, he had to look beyond a water-logged slope where groundcover struggled to survive. The client had mandated a pool on a level side lot, but Dunlevy saw opportunities in the slope: With courageous use of cut-and-fill excavation, he addressed runoff—and was able to add an understated pool and plantings worthy of a Heritage award. “Now the client has an asset rather than a liability,” he observes.
The slope dipped 30 inches to the property line. By constructing a 36-inch-tall retaining wall at the boundary and filling it tightly with excavated soil, Dunlevy gained the right elevation for the rectangular pool with space for a spa that spills into it and a circular stone fire pit. Arborvitae and cryptomeria provide privacy. A historic wood-frame garage at one end of the pool dictated the design of an attached outdoor changing area while providing space for equipment.
The pool is bounded by a thermal Pennsylvania flagstone terrace to match an existing upper patio. A meandering path is enlivened with camellia and a Japanese maple. Out of sight but not out of mind is a large dry well topped with a bed of river stones, which manages runoff to adjacent properties. Says Dunlevy, “I always try to be as neighborly as possible. It costs a little more, but it will pay off in the end.” And that flat side lot? It became a baseball diamond.
