Centre & Herron Stormwater Project

Completed Stormwater

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.

A portion of the Centre and Herron project featuring rainwater flowing into a weir and part of the bioswale.
