Environmental Consulting Services for Affordable Housing Redevelopment of Former Mill

Killingly, Connecticut

Services: Environmental Investigation and Remediation
Clients Served: Government and  Property Developer

A vacant textile mill property that was originally constructed in 1863 is being demolished, remediated, and redeveloped as a multi-residential apartment complex for low income affordable housing.

Loureiro completed multiple phases of environmental investigations, including Phase I Environmental Site Assessment (ESA), Phase II subsurface investigations, and Phase II/III supplemental subsurface investigations on behalf of the State of Connecticut Department of Economic and Community Development (DECD), Office of Brownfield Remediation and Development (OBRD) and the Town of Killingly. These investigations defined the nature and extent of pollution from contaminants and determined that remediation is required. The environmental analysis included a summary of the soil and groundwater impacts and a summary of the proposed project and environmental factors as well as a remediation plan.

Additionally, Loureiro also assisted the property development company that is planning to convert the mill into a housing development with various grant and loan applications (USDA, DECD). As a result, the company received a grant from DECD in the amount of $2.02M for the planned demolition, abatement of hazardous building materials (HBM), and soil remediation. The proposed land and property uses included preservation and reuse of one existing historic stairwell. New building offices, a community room, maintenance and heating/cooling infrastructure are also being proposed in various areas of the building.

Demolition, abatement, and remediation is planned for late 2014 and 2015 and includes removal and disposal of existing underground and aboveground storage tanks, excavation and off-site disposal of contaminated soil, the installation of an engineered control cap, excavation and consolidation of impacted soils beneath the engineered control cap, and the installation of a passive sub-slab depressurization system beneath the proposed building.
