WAUKESHA, Wis. — Waukesha County has agreed to sell the former UW-Waukesha campus to Milwaukee-based developer F Street, which is proposing a roughly $150 million housing development on the 80-acre property. The project is expected to include nearly 600 housing units, including single-family homes and apartments. Plans remain preliminary and will require approval from the city of Waukesha before construction can proceed. Demolition of existing campus buildings could begin later this year, with construction expected to unfold in multiple phases over approximately seven years. The county has not disclosed the purchase price because the transaction is still being finalized, but officials said F Street submitted the highest-value proposal. The sale is expected to close in the coming weeks. Mayor Alicia Halvensleben said the redevelopment would return a large property to productive use and add it to the city’s tax base. She also described the site as a rare opportunity as undeveloped land becomes harder to find in Waukesha. “It's a beautiful part of Waukesha, it really is,” neighbor Cindy Nickles said, adding that she worries the project could substantially change the area. Other residents said the proposed number of homes could bring heavy traffic. “If that many people are going to be living up there, this place is going to be completely back-to-back traffic,” neighbor Scott Watson said. Halvensleben said residents will have opportunities to weigh in as the development advances through its phases and required approvals. The final layout, housing mix, traffic plans and other details have not yet been determined. The UW-Waukesha campus closed in 2025 amid state higher-education budget cuts. Its redevelopment would replace a former public college campus with a large residential community, making decisions about density, transportation, infrastructure and neighborhood impacts central to the city’s review.
