Different plants and soil for the bioretention at Glen Eden Pilot Park

Glen Eden Pilot Park Bioretention Area

Green Stormwater Infrastructure

We are constructing a bioretention area at Glen Eden Pilot Park. The project is engineered to capture, absorb, and clean stormwater runoff. The plants, mulch, soil, gravel, and underground pipes will:

  • Slow down the water; and,
  • Filter out water pollution before it reaches House Creek and Crabtree Creek.

The parking lot off Eden Croft Drive is closed during construction. More details below.

Construction

Completed Work

Prep Phase 

  • Surveyed the area before working on the bioretention area
  • Added fences that keep sediment in the project area and protect nearby land; and,
  • Removed trees in the project area.

Active Construction

  • Excavated the land for the bioretention area; 
  • Installed the pipes, stone, and soil in the bioretention area; and,
  • Stabilized the area with temporary vegetation. 

Paving (as early as Sept. 16)

Crews will be paving Carlow Court. This work doesn't require a road closure. Construction crews will flag traffic around the work. 

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

Parking Lot Closure Extended to October

The parking lot off of Eden Croft Drive will be closed until October. Originally, we planned to open the parking lot sooner. However, the contractor adjusted the schedule for the four green stormwater infrastructure projects. Crews will be back on site soon to finish the project. If anything changes, we will let you know. 

Planning a visit? You can park at 1500 Glen Eden Drive. Please use the greenway trail next to the building to access the playground.

Next Steps

 

Crews will be adding mulch and plants to the project area. They will also be doing concrete and asphalt work to direct stormwater runoff into the bioretention area. This will be done in September.

Background

The nearly 2,000-square-foot bioretention area will capture stormwater runoff from about a half acre of impervious surface (streets, driveways, and rooftops). The area is expected to prevent excess nitrogen and total suspended solids from polluting waterways each year. 

  • 4 pounds of nitrogen
  • 69 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.
