Plan Commission - Oct 1, 2026
The draft code would require data centers to go through a planned development rezoning with two public hearings, plus a long list of performance standards. A resident asked the commission to hold the data center section back until a companion ordinance with extra guardrails is finished; the city has a 12-month moratorium in place.
City Council Meeting - Sep 28, 2026
The council adopted a moratorium on data centers citywide after residents pushed for time to write zoning protections covering water use, air quality, the grid, and quality of life. It follows the divisive Viridian proposal at the GM/JATCO site.
GM/JATCO Redevelopment Advisory Board - Sep 16, 2026
The next big chance for residents to shape the former GM/JATCO redevelopment is an in-person open house on October 14 from 5 to 7 p.m. at Hyatt Smith Commons. Three early concepts will be on display, and there's no online option this time, so attending matters.
City Council Meeting - Sep 14, 2026
The city is considering a pause on data centers while it finishes rewriting its zoning code and a 'guardrail' ordinance. Five residents spoke in favor, citing water use, noise, light pollution, and the need for due diligence. A public hearing and possible vote come September 28.
City Council Meeting - Aug 24, 2026
A resident urged the council to consider partnering with Habitat for Humanity to build affordable housing on part of the former GM/JATCO site, citing Habitat's volunteer labor and sweat-equity model.
City Council Meeting - Aug 10, 2026
A resident urged the council to reconsider data-center plans for the former GM/JATCO site, noting Rock County townships have imposed moratoriums and that the $30 million remediation may be avoidable by capping with concrete.
GM/JATCO Redevelopment Advisory Board - Jul 23, 2026
The community's wishes for the old GM/JATCO plant site are taking shape: trails, green space, a grocery store, jobs, and a mix of housing top the list. How industrial, residential, and recreational uses balance out will be tested at the October design workshop.

City Council Meeting - Jul 13, 2026
Voters will decide in November whether big development deals on the former GM sites — over $450 million — should require a majority vote of the electors, following a direct legislation petition.
City Council Meeting - Jun 22, 2026
The council unanimously told staff to draft a companion ordinance covering monitoring, enforcement, cost recovery and more for any future data centers — citywide, not just for the GM site. A public feedback session comes first, and it dovetails with the ongoing zoning code rewrite.
GM/JATCO Redevelopment Advisory Board - May 27, 2026
Soil contamination is documented on the north manufacturing side, the sediment repository, and former fueling areas; other areas still need assessment. This shapes what land uses are realistic — single-family housing on the north portion would be costly and likely not market-feasible.
City Council Meeting - May 26, 2026
A resident with Snow Janesville warned that the draft zoning rewrite currently allows large data centers by right on industrial land with no public hearings, and urged the council to require their own zoning designation, big setbacks, developer-paid costs, decommissioning bonds, and independent impact studies.
City Council Meeting - May 11, 2026
Speakers floated ideas for the former GM/Jatco property, including using it for 4-H fairgrounds and questioning prior transaction decisions.
City Council Meeting - Feb 9, 2026
The city is negotiating with Viridian Partners to sell 250 acres of the old GM site for a data center that could bring $4.2 million a year in city tax revenue — but residents collected 4,670 signatures demanding a public vote on mega-projects there. The council sent the question to the November ballot instead of adopting the ordinance, so the community's say comes in the fall.
City Council Meeting - Jan 26, 2026
A citizen petition with about 4,600 signatures would require voter approval for development projects over $450 million or any transfer of the GM/JATCO site — aimed squarely at the proposed hyperscale data center. The council declined to fast-track it to the April ballot and will hold a public hearing February 9 instead, likely teeing up a November vote.

The project could reshape the south side with major energy, water, and tax implications — and only around 600 jobs versus the 4,000 the GM plant once employed, according to speakers.
