This site is being acquired by the Cook Inlet Housing Authority (CIHA) to add to their neighborhood revitalization efforts in the economically disadvantaged and heavily blighted Spenard Road corridor in Anchorage. CIHA applied to DEC for assistance in clarifying site conditions before the pending property transfer. The general area-wide plan for the neighborhood is to replace the light-industrial property uses with new retail businesses, housing, and public use spaces. The owner of the property, while possibly considered a financially viable responsible party by the State, has not been diligent in responding to recent requests from DEC to comply with regulatory requirements for site characterization, cleanup, and regular monitoring. The property has several liens on it that will prevent the owner from receiving a windfall in the final sale. The CIHA has resources to obtain funding for the necessary remediation and redevelopment of the property.

DBAC services for this site has included a Phase I Environmental Site Assessment (ESA), to fulfill CIHA’s due diligence, all appropriate inquiry requirements. The Phase I ESA also is required by CIHA’s partner funding agencies. In addition to the Phase I ESA, DEC assisted CIHA with an evaluation of the steps needed to bring the site into regulatory compliance and the remedial actions necessary to proceed with the intended redevelopment. Pursuant to those two activities, DEC completed limited plume delineation offsite, sampled existing wells on the property, and conducted additional soil and soil-gas sampling. DEC also assisted CIHA in obtaining an EPA Targeted Brownfield Assessment to further clarify cleanup requirements in 2013.
