Soakage Trenches

Shallow lined trenches treat stormwater runoff from hard surfaces

Drywells

Underground perforated pipes collect stormwater and allow it to soak into the ground

Turf Block

Turf block allows rain to infiltrate parking areas, driveways and walkways

Pervious Pavement

Pervious pavement resembles conventional paving material but allows stormwater to infiltrate

Pervious Pavers

Pervious pavers allow stormwater to soak into the ground and reduce runoff

Infiltration Planters

Infiltration planters work well in space limited sites with good drainage

Flow-Through Planters

Flow-through planters manage stormwater in areas not suitable for infiltration

Vegetated Infiltration Basins

Rain gardens can dramatically reduce stormwater flow rates and volume

Vegetated Swales

Gently sloping, vegetated depressions that collect and treat stormwater runoff

Contained Planters

Contained planter boxes reduce impervious area and stormwater volume

Trees

Information about the stormwater management benefits of trees

Roof Gardens

Heavyweight roof systems that manage stormwater

Ecoroofs

Managing stormwater with lightweight vegetated roof systems

Cisterns

Storing stormwater runoff for reuse

Rain Barrels

Using rain barrels to collect roof runoff for re-use

Downspout Disconnection

Redirecting roof runoff from the sewer system
