School Street Parking Lot Green Infrastructure Project, Borough of Etna, PA

Completed in June 2014, this project uses new technology and a unique stormwater best management practice consisting of a 20-SF high-rate biofiltration system directly capturing runoff water into a 1,060-cubic-foot stormwater management unit where it is stored and infiltrated.

The facility receives runoff from more than an acre of contributing area and is projected to capture approximately 540,000 gallons of stormwater annually from the Borough’s combined sewer system.

BH provided the design and construction management for this project developed with funding assistance from the Richard King Mellon Foundation through 3 Rivers Wet Weather to show the value of adding green stormwater features as part of the reconstruction of the parking lot at a more affordable cost.
