Glenwood Avenue Bioretention Area

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're also adding a sidewalk along St. Marys Street that will connect to the sidewalk on Glenwood Avenue. This work is partially funded by the Transportation Department

Wake Drive at Glenwood Avenue is closed. More details below.

Construction

Lanier Construction Company is working on four green stormwater infrastructure projects in Raleigh. 

Crews are almost finished installing the bioretention area. This includes: 

  • Excavating land in the project area; 
  • Grading the site; 
  • Installing pipes and drainage structures; and, 
  • Seeding, planting, and mulching the area. 

There also will be a fence along part of the sidewalk in the project area. Paving is tentatively scheduled for  September 29. 

Regular work hours are Monday - Friday from 8:00 a.m. - 5:00 p.m. 

Weekend Work - Sept. 25

Crews will be working on Saturday, September 25 from 9 a.m. - 5 p.m. They are finishing work that they couldn't do this week due to weather.

Road and Lane Closures

Wake Drive Closed Until October

The contractor closed Wake Drive at the entrance of Glenwood Avenue. People who live on Wake Drive can access the road from St. Marys Street. The road will be blocked to all other traffic while crews work on the bioretention area and sidewalk. 

St. Marys Street

The closure for the right turn lane ended on Sept. 14. 

Planting the Bioretention Area

We are planting over 750 plants and six trees for the project. This will create a green, aesthetic space that is also eco-friendly.

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.
