Improving Our Community Waterways Together

Portland Green Infrastructure

Portland Green Infrastructure Project (CSO190)

The Portland Green Infrastructure Project will prevent more than 35 million gallons of rainwater from entering the combined sewer system in a typical rainfall year, and provide sewer overflow protection for the Ohio River. Input from the neighbors—at public meetings and online—will help determine the aesthetics of the finished project. All green infrastructure elements will be in the right-of-way. MSD will be responsible for maintenance of these features.

Green infrastructure focuses on the preservation and restoration of natural landscape elements—rainwater storage and infiltration—by implementing green practices that mimic predevelopment conditions. Capturing stormwater on-site has proven to be a cost-effective solution for reducing rain flow to the sewer, thus decreasing sewer overflows.

This project will provide the following community improvements:

  • More trees and vegetative plantings
  • Enhanced roadway surfaces and sidewalks

Construction is set to begin for Phase 2 of the Portland Green Infrastructure Project.

This project—which captures stormwater from the 145-acre CSO 190 sewershed—will relieve sewer overflows into the Ohio River, west of downtown. Phase 2 green infrastructure will be installed at several sites within an area bounded to the south by Jefferson Steet, to the north by Portland Avenue, to the west by 18th Street and on the east by 15th Street. Curb inlets at the intersections will direct rainwater to planting areas and underground trenches, which will allow for absorption of the rainwater deep into the ground.

When all phases are complete, this initiative will prevent more than 32 million gallons of sewer overflow from exiting the combined sewer system at CSO 190 in a typical rainfall year.
