Janesville, Wisconsin is seeking public input on the redevelopment of the former GM/JATCO site after a proposed data center project was taken off the table. Community concerns about water and noise pollution contributed to the decision not to proceed with a data center-focused firm. The City Council also voted to include a referendum on the November ballot that would require voter approval for any development project exceeding $450 million.

Janesville, Wisconsin, is actively seeking community input for the redevelopment of the former GM/JATCO industrial site, as a proposed data center project for the location has been dismissed. Following a community vision workshop with over 150 attendees, the city launched an online survey, open until July 8, to gather residents' preferences for the 250-acre south side property.

Nick Faust, assistant to the city manager, explained that the redevelopment plan emphasizes the alignment of market, land, and community interests, necessitating strong community buy-in. Initial ideas for the site include housing, commercial space, manufacturing, and open spaces. The city and its consultant, Stantec, are in the early stages of an 18-month planning process, which involves market data collection, environmental reviews, and continuous community engagement.

The potential data center had been a significant topic for months, with residents expressing concerns over water and noise pollution. In February, the Janesville City Council moved to place a referendum on the November ballot, which, if approved, would mandate voter consent for any development project exceeding $450 million. This week, the council further solidified its shift by voting against extending a letter of interest with Viridian, a firm specializing in brownfield redevelopment for data centers, thereby removing their data center proposal from consideration.

The results of the public input will be presented to the Redevelopment Advisory Board in late July, with a complete draft plan expected to go before the City Council for adoption after additional community engagement activities, including a design workshop later this year.
