Project Summary
Constructed in 1893, the Durango Powerhouse, designed in historic Mission-style architecture, is the oldest standing alternating current (AC) coal-fired power plant in the world. By 1972 after nearly 80 years of operations, the Powerhouse building sat idle and vacant, riddled with environmental contamination. In the mid-1990’s, the City of Durango eventually purchased the property and site. However, funding for remediation and renovation proved to be difficult.
Founded in 1994, the Children’s Museum of Durango (operating under Durango Discovery Museum) eventually outgrew their original 1,100 square feet facility. In 2002, the Children’s Museum contacted the City and submitted a proposal for converting the historic plant into an interactive science museum. The Durango City Council responded positively to the proposal by passing a resolution supporting the restoration and conversion of the Powerhouse into the Durango Discovery Museum. Beginning in 2002, volunteers began obtaining grants for historical renovation, asbestos removal, and site cleanup from the State of Colorado.
By 2006, after significant fundraising and cleanup, the brownfield remediation of the site and the exterior renovation of the Powerhouse had been completed while the interior renovation of the Powerhouse into an interactive exhibit space took an additional four years to conclude. The museum opened to the public in February 2011. Since 2011, the museum has continued to evolve with new exhibit and education space, administrative offices, and a café being added.
Environmental Challenges
The Powerhouse site contained several environmental concerns, including unknown levels of asbestos and other contaminants as well as decades of pigeon waste buildup. In addition to containing visible remnants of coal and other byproducts from the plant’s operations, the soil was also contaminated from radioactive tailings from a nearby site. Lastly, the soil was compromised by a petroleum plume which extended from a nearby gas station’s underground storage tanks. Remediation efforts included physically removing the contaminated soil and hot spots from the site. Mitigation of the radioactive tailings included infilling with pea gravel and a drainage net to filter out the tailings without compromising the drainage system. The most expensive part of the cleanup was due to asbestos in the plant’s building materials. All of the remediation was made possible through grants provided through state (CDPHE) funding.
Financing and Deal Structure
The total cost of the restoration project was estimated to be approximately $4 million. Multiple entities partnered together to address the financial needs of the redevelopment by fundraising, collecting grant money, contributing countless hours of volunteer work, and garnering state support. From the state, the project qualified for a Targeted Brownfields Assessment of $135,000. Of this amount, approximately $45,000 came from CDPHE’s Section 128(a) State and Tribal Response Program Grant to perform assessments on initial contamination assumptions. Another $90,000 came from state funds for the removal of asbestos and more than 1,000 cubic yards of contaminated soil. Public and private donations contributed another $2 million and included $100,000 from the Gates Family Foundation and $50,000 from BP America for solar equipment. In addition, many local firms donated time, labor, and materials.
