Best Management Practices (BMP) Construction Projects

New Rain Garden topsoil during construction.1. Spring Street Rain Gardens (De-combination BMPs)

  • Location – South side of Spring Street between 4th Street and Root Street.
  • Purpose – Cleans and infiltrates stormwater runoff from Spring St. and adjacent property. Uses rain gardens planted with landscaped native plants and the existing sand and gravel beneath the rain garden to clean and infiltrate the stormwater.
  • Size - Five 50 foot long rain gardens. The BMP area is 2700 square feet (0.062 acres).
  • BMP Design - Fully treats the first 3/4 inch of runoff from 1.3 acres of residential street and adjacent property. Existing sand and gravel beneath the BMP provides excellent infiltration.
  • BMP Benefit - Decreases the total volume of runoff by 72%. Removes 288 lbs of total suspended solids and 113 lbs of chemical oxygen demand per year.
  • Status - Completed Spring 2010.

 

bio filtration2. Bio-filtration Facility (Lincoln Avenue Parking Lot)

  • Location – Northwest corner of Spring Street and Lincoln Avenue in the METRA commuter parking lot.
  • Purpose – Cleans stormwater runoff from the parking lot before the runoff flows to the Fox River. Retrofit of an existing detention basin to provide bio-filtration using native plants and a sand filter to clean the stormwater.
  • BMP Size - The BMP area is 3100 square feet (0.07 acres).
  • BMP Design - Fully treats the first ¾ inch of runoff from 4.5 acres of commuter parking lot.
  • BMP Benefit - Decreases the peak discharge rate by 25%. Removes 5,612 lbs of total suspended solids and 1,342 lbs of chemical oxygen demand per year.
  • Status - Completed Spring 2010.

3. RiverEdge Park Stormwater Wetland Bio-swale

  • Location - Along the bike path on the east bank of the Fox River across from the U.S. Post Office on Broadway Avenue.
  • Purpose - Cleans stormwater runoff from an existing storm sewer before the stormwater flows into the Fox River. Uses a manufactured stormwater quality unit and a bio-swale planted with landscaped native vegetation to detain and clean the stormwater.
  • BMP Size - The BMP area is 6500 square feet (0.15 acres).
  • BMP Design - Fully treats the first¾ inch of runoff from 5.2 acres of Broadway Avenue and industrial parking lots.
  • BMP Benefit - Decreases the peak discharge rate to the river by 80%. Removes 7,700 lbs of total suspended solids and 1,813 lbs of chemical oxygen demand per year.
  • Status - Completed Spring 2010.

4. Green Infrastructure for CSO Control (Rain Gardens East Side)

  • Location - At 17 select intersections along Simms St. and 4th St. from Galena Blvd. to Euclid Ave.
  • Purpose - Removes storm water from the combined sewer to reduce basement backups and combined sewer overflows. Allows storm water to infiltrate into the ground, providing water quality improvements. Plants promote evapotranspiration, produce oxygen, and reduce urban heat island affects. Also, the area provides traffic calming and reduces cut through traffic, and shortens cross walk lengths, improving safety for motorists and pedestrians.
  • BMP Size - varies depending on intersection.
  • BMP Design - Uses amended soil and perennial plants, bushes and trees to infiltrate and treat storm water runoff. Existing subsurface sand and gravel promotes infiltration of water into the ground.
  • BMP Benefit - Decreases volume and peak runoff of storm water from the combined sewer. Promotes infiltration to reduce total suspended solids. Reduces volume of water entering combined sewer, which reduces basement backups and combined sewer overflows to the Fox River.
  • Status - completion fall 2014

Naturalized Stormwater Management Corridor Plan (NSMCP)

  • Purpose – A comprehensive analysis of the land use, topography, soil, stormwater and estimated pollutant load of the study area to determine recommended green infrastructure implementation; and to assess the impact of green infrastructure implementation on reducing the total stormwater runoff volume and pollutant load from the study area. Provides a plan for a naturalized, dispersed, stormwater management system within the study area.
  • See the Naturalized Stormwater Management Corridor Plan for the Study Area: Link to NSMCP coming soon.
