"The University of Wisconsin – Madison (UW-Madison) Facilities Planning and Management has retained Ayres Associates on behalf of the University of Wisconsin System Administration (UWSA) to prepare an Environmental Impact Assessment (EIA) addendum for Phase 1 of the proposed improvement of thermal utilities at UW-Madison along Science Hall in Madison, WI. This EIA addendum outlines additional scope items and their impacts and is prepared in accordance with the Wisconsin Environmental Policy Act (WEPA), Wisconsin Statutes 1.11, and UWSA guidelines (Board of Regents’ Resolution 2508, November 6, 1981). The purpose of the EIA addendum is to assess potential impacts of the additional project elements on the physical, biological, social, and economic environments surrounding Science Hall. PROJECT DESCRIPTION: The additional project work described in this addendum proposes to construct a new steam tunnel around the south and east side of Science Hall, located in the Bascom Hill Area of the UW-Madison campus. Attachment 1 provides associated figures describing this project scope and limits of construction. Upon completion of the utility system, all areas disturbed by the project will be fully restored, including roadways, gutters, sidewalks, landscaping features, and site structures. Work for design and construction of the addendum scope is included in the original project budget. The project was enumerated in the 2017-19 UW System and State of Wisconsin capital budget with an authorized budget of $32,656,000, related to the thermal, civil and electrical distribution systems by replacing, upsizing and adding the necessary infrastructure to complete the utility transmissions. Total budget costs are estimated to be $32,656,000. $23,839,000 of funding will be sourced from General Fund Supported Borrowing and $8,817,000 will be sourced from Program Revenue Supported Borrowing. Phase 1 of the project is estimated at a total cost of $20,076,000."--From the introduction.
