This is an Environmental Site Assessment Conclusions and Recommendations attachment related to the City of New Haven, Connecticut's Phase III site investigation and Remedial Action Plan development for 0 Gibbs Street, a 1.15-acre property formerly operated as a commercial cement mixing plant. The City is soliciting proposals from Licensed Environmental Professionals to complete the Phase III investigation, prepare the final Remedial Action Plan, and develop bid documents for remediation contractors, with the ultimate goal of remediating the contaminated site for conversion into a public park. Previous environmental investigations have identified petroleum constituents, metals, and other hazards in soil and groundwater. A pre-proposal meeting is scheduled for January 7, 2026, at 11:30 a.m. at the property location, with questions due by January 14, 2026, at 5:00 p.m., and proposal submissions due January 27, 2026, at 11:00 a.m. through the City's electronic procurement portal. The contract term is one year with one optional one-year extension subject to the Purchasing Agent's approval, with a tentative schedule indicating contractor selection by February 6, 2026, contract execution by March 6, 2026, Phase III investigation completion by May 1, 2026, final RAP completion by May 15, 2026, and bid document development by June 15, 2026.

The project is funded through a $250,000 grant from the Connecticut Department of Economic and Community Development (DECD), with a portion allocated to consulting services and the balance dedicated to initial remediation activities. Evaluation criteria will weight proposals as follows: experience with urban brownfield sites (25 points), staff qualifications (20 points), ability to perform work timely (20 points), proposed cost (20 points), and references (15 points). The City requires compliance with Equal Employment Opportunity provisions, the Ban The Box Agreement, and a Living Wage Ordinance for contracts exceeding $25,000. Successful proposers must maintain specific insurance coverage, including General Liability ($1,000,000 per occurrence), Workers' Compensation, Auto Liability ($1,000,000), Professional Liability ($1,000,000), and Pollution Liability ($1,000,000).
