Weldon Spring Site Interpretive Center

Construction on the U.S. Department of Energy (DOE) Office of Legacy (LM) Weldon Spring Site New Interpretive Center began in May 2019 and was completed in 2021 under the guidance of the U.S. Army Corps of Engineers (USACE) St. Louis District and LM leadership. The new facility features four classrooms each of which seats 40 people, an auditorium seating 80 people, a 4,500 square foot exhibit gallery with newly fabricated exhibits, and administrative office space for employees. The design of the facility adheres to the Guiding Principles for Sustainable Federal Buildings (Guiding Principles), established by the U.S. Environmental Protection Agency (EPA) in 2006. These Guiding Principles are the federal equivalent to the U.S. Green Building Councils LEED (Leadership in Energy and Environmental Design) certification, a globally recognized symbol of sustainability achievement and leadership.
