Western Milwaukee Phase 2B

Project Update

Work for the project continues both along the river and in State Street. Demolition and removal of old building and railroad materials along the river has taken place to make way for a new levee and floodwall. The river channel is being widened next to Doyne Park ahead of floodwall construction next to the railroad.

Utility work continues in State St between the 4600 and 5200 blocks of State Street. State Street will remain open in both directions though traffic may be moving more slowly. Thank you again for your patience during the construction of this project.

MMSD will send out an email update ahead of work in State Street between the 6000 and 6200 blocks in Wauwatosa. At this time, we anticipate work will begin in July with traffic remaining open in both directions.

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 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 completion. 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 To Reduce Flood Risk
  • Increased Public Safety
  • Improved Riparian (area adjacent to the river) & Aquatic Habitat
