Downspouts (roof leaders) convey roof water to the on-site stormwater service by direct connection or overland via drainage swales.

  • If the downspout is discharging to the ground, it must have an elbow and a hinged extension or concrete splash pad
  • The downspout elbows must be directed away from the foundation walls, towards the drainage swales
  • Downspout extensions or splash pads must discharge within the property
  • Hinged extensions are acceptable only if they do not extend onto abutting public or private property
