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
