Got spring fever? Layers of frozen snow still cover the ground, but come the spring thaw, three developers could break ground on four new industrial facilities that collectively total 460,000 square feet. The city of Janesvilleâs economic development office announced it plans to take three tax-incentive agreements to the city council Monday. One of the deals would help Milwaukee developer Zilber Property Group build on speculation a pair of 178,000-square-foot industrial buildings on 24 acres of city land at Venture Drive and Beloit Avenue. Just southeast of that project, Beloit paper tube manufacturer Western Container Corp. plans to build a 43,000-square-foot manufacturing facility at 1301 W. Venture Drive. The facility is part of a corporate expansion for Western Container, and the city hopes to offer tax incentives, Economic Development Director Gale Price said.
