Peterson Street Stormwater Bioretention Area

Peterson Street Bioretention Area

Green Stormwater Infrastructure

We constructed a bioretention area in the grass median between the sidewalk and road on Peterson Street. The project is engineered to capture, absorb, and clean stormwater runoff from nearby streets and buildings. The plants, mulch, soil, gravel, and underground pipes will:

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

This project is near the Walnut Creek Wetland Center and the Walnut Creek Gravel Wetland.

Complete

Crews finished this green stormwater infrastructure projects in October. This included:  

  • Excavating the land for the bioretention area; 
  • Completing demolition work; 
  • Installing the curb and sidewalk; 
  • Installing the pipe, stone, and media; 
  • Adding soil, mulch, and plants; and, 
  • Installing pavers to help water from eroding the soil near the pipe. 

During the warranty period, crews will make required repairs or maintenance for the project. This period ends in fall 2022.

Background

The 500-square-foot bioretention area will capture stormwater runoff from about 0.3 acres of impervious surface (streets, driveways, and rooftops). The area is expected to prevent excess 2 pounds of nitrogen and 41 pounds of suspended solids from polluting waterways each year.

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.
