Kissel Park Brownfields Redevelopment

For the City of Yakima, Floyd|Snider managed the investigation and cleanup of 17 acres of former orchard land contaminated with lead arsenate. The City planned to develop the site into a modern city park, complete with tennis courts, jogging trails, and picnic areas. The discovery of elevated levels of arsenic and lead, and the high cost to perform the cleanup, prompted the City to seek Remedial Action Grant funding. Floyd|Snider worked closely with the City's legal team to negotiate and obtain an acceptable Agreed Order with the Washington State Department of Ecology (Ecology). Subsequent to the Agreed Order, Floyd|Snider performed an RI/FS to characterize contaminant levels, and developed a Cleanup Action Plan that integrated cleanup elements with the overall design of the park. Floyd|Snider provided essential negotiation support, working closely with Ecology to ensure that the cleanup was conducted in accordance with the Model Toxics Control Act (MTCA) and other Ecology requirements. Floyd|Snider also performed a pilot study of deep tilling methodologies for Ecology prior to full-scale cleanup. The objective of the pilot study was to evaluate the effectiveness of tilling the arsenic-contaminated soil into deeper, less contaminated soil. In 2003, the park cleanup was completed.
