Project Description

This project involved the demolition, remediation and redevelopment of a former dye manufacturing plant which had operated in Buffalo, NY since the early 1900’s and occupied nearly 40 acres of property. The highly contaminated site was cleared through the NYS Brownfield Remediation program, which created development incentives for the Heritage Discovery Center.
