A home at the bottom of a hill tends to get a lot of water when it rains. A soggy yard and flooded basement was de rigeur for the clients, two busy Washington DC professionals and their daughter. Their goal… no flooding, and an ability to utilize their narrow side yard. Our sustainable landscape design solution included a long, narrow flagstone patio that appears wider because of the bowed dining patio bordered by a seat wall. The seating wall defines the patio perimeter and offers a casual perch for party guests. Rainwater is captured at the base of the seating wall and distributed among nearby planting beds. A permeable brick pathway from the parking area absorbs stormwater run off from the up hill neighbors, re-charges the ground water levels, and irrigates the native landscape built alongside. We also dug a bio swale to channel water into another conservation area that includes native trees and shrubs.
