• Introduction

Drywells

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

Downspout Disconnection

Redirecting roof runoff from the sewer system

Turf Block

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

Flow-Through Planters

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

Vegetated Swales

Gently sloping, vegetated depressions that collect and treat stormwater runoff

Infiltration Planters

Infiltration planters work well in space limited sites with good drainage

Soakage Trenches

Shallow lined trenches treat stormwater runoff from hard surfaces
