Green Streets in CSO 052 Sewershed (Elmwood Neighborhood)

 

Project Description: The Green Streets in CSO 052 Project is another example of the Save the Rain Program targeting a specific priority area for green infrastructure implementation. This application, within the high priority CSO 052 sewershed, is intended to reduce pollution to Onondaga Creek and Onondaga Lake. The project will be located on seven streets within the City: Elmhurst Avenue, South Avenue, Charmouth Drive, Fairfield Avenue, Fletcher Avenue, Edgewood Avenue, and Hutchinson Avenue.

The project will use two types of green infrastructure technology: underground infiltration trenches, and rain gardens (also known as bioretention). These green infrastructure practices will provide water quality improvement through infiltration and storage, reducing overflows. In total, the project consists of 22 underground infiltration trenches and 1 rain garden. The underground infiltration trenches provide a very high capture volume without an obtrusive footprint at the surface, maximizing cost efficiency.  The County and City will simultaneously be offering street tree plantings within the neighborhoods.

Upon completion of all seven streets, the project will capture runoff from approximately 9.75 acres of impervious area, reducing stormwater runoff to the sewer by approximately 6.5 million gallons annually. Project areas include:

  • Charmouth Drive from Robineau Road to Arlington Avenue – 6 underground infiltration trenches;
    annual stormwater runoff capture: 1,800,000 gallons
  • Fairfield Avenue from Fletcher to South avenues – 1 underground trench, 1 bioretention area; annual stormwater runoff capture: 437,000 gallons
  • Hutchinson Avenue from Clayton to South Avenues and Fletcher and Edgewood Avenues from Hutchinson to Fairfield avenues – 7 underground infiltration trenches; annual stormwater runoff capture: 2,190,000 gallons
  • South Avenue from W. Brighton to Eastman avenues – 4 underground infiltration trenches; annual runoff capture: 938,000 gallons
  • Elmhurst Avenue from Bishop Avenue to Hunt and Randall Avenues 3 underground infiltration trenches; annual runoff capture: 1,222,000 gallons
