TARGETED BROWNEIELDS ASSESSMENT
TRINITY-IMANI VILLAGE - 95TH AND COTTAGE GROVE
REUSE/REVITALIZATION
DETAILS OF U.S. EPA'S SITE ACTIVITIES
Chicago, Illinois	December 2017
The United States Environmental Protection Agency's Targeted Brownfields Assessment, or TBA, Program assisted the Trinity 95th
and Cottage Grove Planned Community Development, LLC by completing a TBA for a property located at 95th Street and Cottage
Grove Avenue in Chicago. At the time of the TBA, the site encompassed 30 acres and contained commercial-industrial properties
and vacant land. The property included five buildings, rail spurs,
and vacant areas. Various companies occupied the property
over the years including American Brake-Shoe & Foundry Co.,
Guardite Corp., Tubular Service, Pennville Corp., and Cavexsa
USA. Several environmental investigations were conducted for
portions, or parcels, of the property, but none that encompassed
the entire property. Previous investigations included site
inspections and soil sampling. The results of these investigations
indicated the presence of soil contamination at the site.
The anticipated future land use of the property is a multi-use
redevelopment known as Trinity-Imani Village. This includes a
proposed charter school, a recreational and community center, a
medical facility, independent senior living facilities and an urban
agricultural center.

The TBA conducted by U.S. EPA was done on all of the
parcels involved in the redevelopment and included a Phase I
Environmental Site Assessment, or Phase IESA, and an Illinois
Site Remediation Program, or SRP, compliant Comprehensive
Site Investigation, Remediation Objectives Report, Remedial
Action Plan, or CSI/ROR/RAP. The Phase I ESA included
reviewing property records and historical documents and site
inspections. The CSI/ROR/RAP included sampling of soil,
groundwater, concrete, slag and soil gas.
U.S. EPA enrolled the site into the SRP and worked closely with
the Illinois EPA project managers early on in the project to
ensure the site assessments were in compliance with the SRP
and to streamline the report review process. In addition, Illinois
EPA worked closely with the site owner and developer to ensure
understanding of the SRP. U.S. EPA submitted three addendums
to the CSI/ROR/RAP for Illinois EPA to provide updated site
development information and additional data obtained due to
revised site plans.

REPORT/INVESTIGATION FINDINGS
Findings of the Phase I ESA indicated potential contamination
from former site activities; suspected asbestos-containing
material and lead based paint; and potential hazards associated
with underground storage tanks from nearby properties.
The CSI findings indicated that soil, slag and groundwater at
the site was contaminated at levels that must be addressed.
Contaminants found in concrete and soil gas were below levels
that require action to be taken. The redevelopment plans include
creating engineered barriers and using institutional controls,
such as groundwater use restrictions, at the site to protect people
using the property in the future.
What is a Targeted Brownfields Assessment?
U.S. EPAs TBA program provides technical assistance
to states, communities and non-profit organizations,
to minimize the uncertainties of contamination on
brownfield sites. U.S. EPA, at no charge to the community,
will characterize a brownfield to determine the nature
and extent of contamination. For more information
