Once the new building is complete, a roughly 60-year-old state office building at Hill Farms will be demolished, and its land used for the private development.

More than 100 people turned up at a community meeting Wednesday at Covenant Presbyterian Church to hear about and weigh in on the proposal.

A major concern for attendees was the density and any parking spillover into the surrounding neighborhoods. On the University Avenue side, buildings could reach up to 15 floors.

Sean Roberts, vice president of development for Summit Smith, said the height would be comparable to two nearby 12-story condo buildings off North Segoe Road. Residential buildings on the Sheboygan Avenue side of the development would stand three stories.

“The massing we’re going to show is based on the concept now,” Roberts said. “None of those projects are fully cooked.”

Smith Gilbane also plans to create a one-acre green space in the center of the Madison Yards project, but several residents criticized the amount of area dedicated to open and green space compared to the overall size of the property.

Others pressed the development team to make strong commitments to sustainable architecture and renewable energy components, such as solar panels.
