Western Milwaukee Phase 2B


Flood Risk Reduction Project

Opportunity for Design Feedback

We want to know what you think! MMSD is completing the final design for the Western Milwaukee Phase 2B Flood Risk Reduction Project. We want your input on the plants, trees, and floodwall pattern. Please click here to complete the survey before July 31st.

For more information about the project join us on Wednesday, July 29th at 6pm for a virtual public meetingClick here to add the meeting to your calendar.  To join the event in progress on July 29th, please click here.

Project Overview

The Milwaukee Metropolitan Sewerage District (MMSD) is partnering with the City of Milwaukee and City of Wauwatosa to make flood risk reduction improvements along the Menomonee River in Western Milwaukee along West State Street between North 60 Street and USH 175.

This project is part of the larger Menomonee River Watercourse Management Plan which aims to reduce the risk of flooding for over 300 homes and businesses. To see the existing floodplain map visit FEMA’s Flood Map Service Center.

The Western Milwaukee Phase 2B Project will:

  • Extend the earthen levee (a compacted soil embankment that holds back floodwaters during heavy rains) 1,900 feet, with a sloped soil embankment up to 8 feet high, to reduce flood risk from the Menomonee River flooding onto State Street during heavy rains from approximately 60th Street and West State Street east to US Highway 175. See bottom of page for example image.
  • Build a 1,200 foot long floodwall (a wall made of concrete that holds back floodwaters during heavy rains) training in a height of 5 to 10 feet on the landward side and up to 20 feet on the river side.
  • Install for new storm sewers totaling 5,100 feet.
  • 1,500 feet of excavation and bank restoration between the north and south banks of the river.
  • Turf and native plantings.

    The Western Milwaukee Phase 2B earthen levee will be similar to the earthen levee down river that was built as part of the Western Milwaukee Phase 1 project.

Project Map

To recognize the levee system's flood risk reduction benefits there will be a levee system accreditation application to the Federal Emergency Management Agency (FEMA) for the entire Menomonee River levee system (shown in map below) and a remapping of the floodplain in the surrounding project area following completion of the project. The FEMA review is expected to take up to three years after construction completionThere are some structures that will remain in the mapped floodplain after the levee system is completed. These structures remaining in the floodplain will be evaluated for other flood risk reduction approaches such as voluntary floodproofing and voluntary acquisition.
