Portions of the main parking area and downspout connections from the building roof will be directed into a bioswale/rain garden feature. This feature will infiltrate stormwater to decrease and treat runoff by reducing pollutants commonly found in this type of runoff.
ACCD will also install a second rain garden near the overflow parking area. This rain garden will capture runoff from the parking lot and upstream inlets along nearby roads. The garden will include an underdrain and bioengineered soil to infiltrate stormwater. A variety of plant species will uptake nutrients and provide pollinator habitat.
ACCD's project is part of more than $325,000 awarded for projects in Allegheny County to reduce pollution. In Pennsylvania, more than $18 million has been awarded to fund over 60 projects to clean up waters.
