Kleinfelder Project Strives for Greener Brownfields

Wednesday, 17 June 2009 13:55

Finding a balanced solution to brownfield redevelopment that takes into account LEED criteria and stormwater regulations often requires the engineering teams to think outside the box.

For example, Kleinfelder used a series of best management practices to turn a hazardous wasteland in Yuma, Ariz., into a cherished archery club by successfully implementing a green brownfield remediation solution.

The 24-acre recreational site had lead concentrations exceeding non-residential soil lead limits by 45 percent. The dynamics of excavation included a $200,000 funding limit, the health and safety hazard, and sustainability in the future public use of the site. The selected remedial alternative needed to address potential lead-exposure pathways for the future use of the site as an archery practice range.

Kleinfelder engineers borrowed from road construction technologies utilized by the Arizona Department of Transportation to design a chipseal cap to cover lead-impacted soils. In addition, to satisfy Flood Control District requirements, the team completed stormwater runoff calculations resulting in design of two retention basins and riprap flood control.

By using this design, Kleinfelder avoided taking the contaminated soil off-site to landfills that would release gases into the air and allowed for the reuse of the land. Furthermore, this plan involved utilizing county personnel to perform the field work, which realized significant cost savings.
