Project overview

The Oliver Avenue South project will build a big underground storage system to hold rainwater under the street.

This will help reduce flooding risks and keep nearby homes and businesses safe.

The project will also:

• Add a new stormwater pipe (called an outfall) that carries rainwater to Lake Harriet

• Replace an old sanitary sewer pipe

• Help water drain better and improve water quality in local lakes and the Mississippi River

Project benefits

• Helps reduce flooding risks for homes and streets

• Improves water quality before it reaches Lake Harriet

• Improves how well the storm and sanitary sewer systems work

• Prepares the system to handle heavier rain in the future

Traffic impacts

Construction will take about one year. People who live or work in the area may notice:

• Temporary road closures and detours

• Limited access to driveways or less parking available

• Construction noise and small vibrations

• Large machines and materials stored nearby

The City will work with residents and businesses to reduce disruptions as much as possible.
