Reaping the Benefits of Brownfield Redevelopment

Challenge

100 acres of a former automobile scrap yard in Andover, Minnesota lay dormant with hazardous soil and asbestos. The site was considered brownfield, and needed remediation before it could be redeveloped into a new commercial development site.

Solution

The City of Andover hired SEH to provide multi-disciplined services to support the redevelopment of a 100-acre contaminated automotive salvage site for use as commercial property. The project’s street, utility, and site grading improvements required the team to balance site improvements with contamination remediation and on-site wetland mitigation. The team worked in coordination with an adjacent landfill property and the local watershed district to minimize collateral impacts.

Features

  • Redevelopment of approximately 100-acre contaminated automotive salvage site
  • Street, utility, and site grading improvements for new commercial use
  • 42-foot-wide roadway, approximately a half mile long

  • Significant environmental remediation work performed to clean up contaminated soils
  • Coordination with adjacent landfill property (superfund site)
  • Significant coordination with the local watershed district for wetland impacts
