Originally a low-lying wetland filled with construction demolition debris and later developed into a Lifetime athletic club, Twin Lakes is an 8.6-acre site bordered by the Twin Lakes Business Park, a residential neighborhood, and Highway 100. The site sat vacant after the athletic club closed was demolished in 2007. It is situated across from the former Joslyn Wood Treating site, a superfund remediated and redeveloped from 1999-2004.
Fill soils without a pattern to the fill ranging from 2 to 12 feet in thickness covered most of the site, with samples showing both carcinogenic and non-carcinogenic PAHs. Petroleum was also detected in samples. Many problematic materials were faced during remediation, including brick fragments, concrete slabs, bituminous fragments, chucks of tar, sewer tile, geotextile fabric, unknown rubber materials, Styrofoam, and metal. Along with 65,000 cubic yards of contaminated fill soil, which was found to be below the groundwater table by as much as 20 feet, six former tennis courts painted entirely with products containing asbestos were excavated from the site. Granular sand was placed at the water table to limit wicking of ground water upwards.
After the cleanup, 90,000 square feet of office warehouse space was constructed on the site. The building has many LEED features including a white roof, extensive glass for natural light, low flow fixtures in restrooms and parking for bikes and hybrid cars. Prairie restoration plantings were used in the landscaped areas to dramatically reduce the water use for irrigation and C02 emission from lawn mowing. Twin Lakes tenants Omicare and Medafor have added 200 medical technology jobs (executives, management, physicians, scientists, pharmacists and warehouse staff) to the community with another 60 projected when fully leased. A paved trail through the site connects different regional trail systems, offering an amenity to the tenants and the community.
