Public Comments & Testimony

• No public comments were recorded.

Discussion Items

• Brand Selection: Amy from Stantec reported that Concept 3.3 received 60% of first-choice votes and 80% as a second choice. The branding, including colors and fonts, will be used moving forward, with potential additions like logos as the project develops.
• Existing Conditions: Amy presented maps covering regional context, land use, zoning, environmental/open space, and mobility. Environmental assessment identified soil impacts on the north (GM) side and documented issues on the south (JATCO) side. The blue area (former rail spur) requires further assessment, while vehicle storage areas pose lower risk. Areas unlikely suitable for single-family residential were identified due to high remediation costs and market feasibility.
• Market Analysis: Jay from Stantec shared initial findings:
  • Population growth in Janesville has been slower than household growth, with an aging population and declining household size (average persons per household dropped from 2.5 to 2.3).
  • Median age rose from ~36 to 41, closing the gap with Rock County and Wisconsin.
  • Married-with-children households declined from 22% to 14%, while living alone increased nearly 6%.
  • Income growth has been uneven; lower-income households are concentrated near the site.
  • Blue-collar jobs dominate employment growth, with the sector having both the highest percentage increase and largest absolute job gains (2013–2023).
  • Housing construction has shifted toward multifamily units. Home values increased 20–30% faster than incomes in Janesville and Rock County compared to Wisconsin state.
  • Multifamily vacancy rates rose slightly in 2025 due to recent construction, but remain healthy.
• Visioning Workshop: Amy outlined plans for a workshop in June (date not specified) from 5–7 PM, likely at the County Resource Center or Fire Station Conference Room. The workshop will use an open-house format with boards, maps, and virtual surveys to gather community priorities on land uses. Stantec will facilitate; city staff and advisory board members may help. A follow-up “what we heard” memo will inform concept designs, with a second workshop anticipated in September.
• Stakeholder List: Board member Aaron Clipstein suggested adding representatives from Jackson, Lincoln, and Wilson elementary schools, Fourth Ward Neighborhood Action Team, Rock County Public Health, the adjacent manufactured home community, and the Rock County Regional Airport (due to FAA height restrictions). Amy confirmed the list is expandable and these suggestions will be considered. Board member James Everstein offered additional data resources.

Key Outcomes

• Meeting adjourned by motion. Lindsay moved, seconded by Jeff. All in favor, motion carried.
• The board directed staff to incorporate suggested stakeholder additions and finalize the list.
• The visioning workshop will be advertised and held in June, with Stantec preparing materials and city staff facilitating.
