Swales are the rectangular grassy areas between the sections of our parking lot.

  • They are designed to capture the rain that flows off the pavement.
  • During heavy downpours, water is slowed, minimizing the risk of flooding.
  • Swales increase water infiltration, filter pollution, and increase ground water.
  • Less rainwater runoff means a cleaner and healthier Chesapeake Bay.
