Downspouts - Commercial and Multi-family
Downspouts (roof leaders) convey roof water to the on-site stormwater service by direct connection or overland via drainage swales.
- If 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 adjacent public or private property
