Trust for Public Land and the City of Saint Paul
Landmark initially worked with the Trust for Public Land to conduct Phase II Investigations and prepare a Response Action Plan prior to the redevelopment of the Bruce Vento Nature Sanctuary, then worked with the City of Saint Paul during the design and construction stages of the project. The 27-acre Sanctuary previously supported a railroad maintenance yard with large-scale petroleum storage, was one of the earliest settlements in St. Paul, and is home to Carver’s Cave, a sacred Native American site.
Landmark worked closely with the multiple government agencies, neighborhood groups and tribal leaders as well as Emmons & Olivier Resources, Inc. and the 106 Group to reshape and redevelop this culturally and historically significant property. Earthwork activities included management of 20,000 tons of soil to redevelop the area with wetlands, ponds, hiking and biking trails, and greenspace with native plantings along this Mississippi River parkland.
Because the work was completed under multiple US EPA Brownfields grants, the soil management plan was critical to the success of the project. A total of 8,740 tons of petroleum, PAH, and metal contaminated soil was excavated for subsequent landfill disposal, and 7,350 tons of soil was reused on site within soil management areas that were then covered with 4 feet of clean soil along with an environmental covenant. After the work was completed, Landmark assisted the City with investigation and cleanup of the adjacent Interpretive Center property that included a similar soil cleanup approach and additional US EPA grant funds.
