Liesch was retained by a national commercial development firm to conduct a Phase I Environmental Site Assessment (ESA) of a 4.35 acre property containing a 138,155 square foot building constructed in four stages. Historically, the building was occupied by grocery wholesalers and retailers, and other tenants of the warehouse space. The purpose of the ASTM Standard Practice E 1527-05 Phase I ESA was to provide due diligence inquiry into the environmental characteristics in connection with the proposed partial building demolition and redevelopment of the property. Historical environmental issues included remaining petroleum and non-petroleum impacts from historic on-site underground storage tanks. Off-site concerns included potential groundwater impacts from a documented release to soil.
