SUSTAINABILITY TOUR: Tour Dupaco/7 Hills Brewery, AlliantSolar Farm, Bee Branch Watershed Project

  • ​Dupaco Tour - Dupaco Community Credit Union is renovating an existing warehouse building for their corporate headquarters in downtown Dubuque using deconstruction and recyclable materials as much as possible.

  • 7 Hills Brewery Tour, led by Keith Gutierrez - 7 Hills is an Iowa Green Brewery in the Dubuque Warehouse District.

  • Alliant Solar Farm Tour, led by Jo Macal - Alliant Energy has placed two solar arrays in the Dubuque Area. Participants will view the one located in an formerly unused area next to highways overpasses.

  • Bee Branch Watershed Tour, led by Steve Sampson Brown - The Bee Branch Creek Restoration involved replacing almost one-mile of storm sewer with a creek and floodplain that resembles the one that traversed the area approximately 100 years ago. This “daylighting” of the buried Bee Branch Creek allows stormwater from flash floods to safely move through the area without flooding adjacent properties.

*Closed-toe shoes are required for this tour.​​​


This event is hosted jointly by the Iowa Recycling Association and Iowa Society of Solid Waste Operations.
