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

Water and Sewer

Glen Eden Pilot Park Bioretention

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.

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.
