Glenwood Avenue Bioretention

Green Stormwater Infrastructure

We are constructing a 1,700-square-foot bioretention area at the intersection of Glenwood Avenue, St. Marys Street, and Wake Drive. 

The project is engineered to capture, absorb, and clean stormwater runoff. The plants, mulch, soil, gravel, and underground pipes slow down the water and filter out pollution before it reaches Crabtree Creek.

We are also adding a sidewalk along St. Marys Street in the project area that will connect to the sidewalk on Glenwood Avenue.

Construction

We have all the required permits for the project. But, we need to re-bid the project for construction. Once this process is complete, we'll select a construction contractor and finalize the construction contract.

Background

The bioretention area will capture stormwater from .75 acres of impervious surface (nearby streets, driveways, and rooftops). The area is expected to prevent excess nitrogen and total suspended solids from polluting waterways each year. 

  • 6 pounds of nitrogen 
  • 109 pounds of suspended solids

This is a great example of how planted stormwater devices help the environment. The features remove pollution and reduce impacts to stormwater pipes and streams.
