Western Milwaukee Phase 2B

Project Update

Construction for the Western Milwaukee Phase 2B project is moving forward, with completion anticipated in late summer. 

Work in State St. East – Milwaukee 

Replacement of the 50th St. storm sewer is expected to begin the week of 6/29/26. This work is estimated to take 4 to 6 weeks to complete, including road restoration. This will be an open-trench sewer replacement for the southernmost 180 ft. of the road (the alley entrance). During this time, the 50th St. intersection will remain closed, and 50th St. traffic will be detoured to 50th Place.

Menomonee River Floodwall and Levee Construction 

Work continues with an expected completion date for the levee and floodwall in the fall of 2027.

This project will extend the earthen levee system 1,800 feet eastward to reduce flooding along State Street, build a new 1,200-foot-long floodwall, install four new storm sewers, and restore 1,500 feet of banks along the Menomonee River.

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 four 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.

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 the map above) and a remapping of the floodplain in the surrounding project area following completion of the project and completion of other FEMA-required levee accreditation improvements. FEMA review is expected to take up to three years. There 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.

Project Benefits:

  • Help Reduce Flood Risk
  • Increase Public Safety
  • Improve Riparian (area adjacent to the river) & Aquatic Habitat
