This project at the intersection of Centre and Herron avenues directs runoff from surrounding streets into a cascading 585 foot-long bioswale, where it is absorbed by plants or soaks into the ground. Additional stormwater flows into underground storage tanks and is slowly released into the sewer system.
Progress & Status
- As one of three stormwater projects constructed in 2017 to demonstrate the use of green stormwater infrastructure, this project helps to prevent street flooding and overloading of the combined sewer system.
- It is estimated to manage one million gallons of runoff annually.
- It received the 2018 Sustainability Award from the American Society of Civil Engineers (ASCE) Pittsburgh Section.
- This project was partially funded by ALCOSAN’s GROW grant program.
