Oak Creek approves intergovernmental agreement with MMSD for $58M interceptor sewer; city to cover roughly 22% of certain costs

Summary

The council approved an intergovernmental cooperation agreement with the Milwaukee Metropolitan Sewer District for a regional interceptor sewer along S. 27th St., a project estimated at about $58 million; Oak Creek’s utility will own and maintain a deep drop structure and is responsible for roughly 22% of the associated costs and intends to consider special assessments for benefited properties.

An unidentified city representative speaking on behalf of Brian Johnston told the Common Council that the Milwaukee Metropolitan Sewer District is preparing to bid a regional interceptor sewer that will extend about 5,300 feet along South 27th Street from Oakwood Road to the county line.

The presenter described technical elements: a new 24-inch sanitary sewer, a drop manhole requiring a shaft approximately 76 feet deep, and an upsizing at the shaft from roughly a 28-foot to a 35-foot diameter. He said the project estimate is approximately $58,000,000 and that the City utility is responsible for roughly 22% of the costs for the drop structure and shaft; the city utility will own and maintain that structure.

Council moved to enter an intergovernmental cooperation agreement with MMSD for construction of the main interceptor sewer and recorded ayes on the roll call. The presenter said the city intends to return to the council with a proposal for special assessments to recover the city’s cost share from benefited properties.

The council’s approval authorizes the city to proceed with the MMSD-backed project and sets the stage for future action on funding and assessment measures.
