History of Property
• Opened in 1916 as Indiana Coke and Gas Company
• Closed in 1988• Known contaminants
include: benzene, toluene, ethylbenzene, xylene, and polyaromatic hydrocarbons
January 1940
Design Requirements
• Brownfield considerations
• Environmental remediation
• Commercial and industrial use
• Hulman and 13th Street improvements
• Railroad access to site
• Location of detention pond

Development Scenarios
Progress to Date
• Development Envelope
• Topographic Survey
• Low Impact Development (LID)
• Codes and Regulations
• Subsurface Conditions
• Begin Phase II Review
Int. of 13th Street and Lockport Road
September 2004
Development Envelope
• Availability and location of utilities
• Floodplains, wetlands and underground mines
• Right-of-way
• Zoning restrictions
• Soil contamination
Holey Moley 800-382-5544
Topographic Survey
• Rough topographic survey completed
• Obtained complete survey performed by American Consulting Inc.
• Compared two surveys to ensure accuracy
Low Impact Development
• Bioretention considerations
• Vegetated swales
• Pervious pavements
• Cisterns
• Cost analysis
Codes & Regulations
• Risk Integrated System of Closure (RISC) document
• Federal contamination guidelines for ground water
• Design Standards and Specifications Terre Haute and Indiana Department of Transportation
Subsurface Conditions
• Preliminary geological investigation
• Compared with soil borings from Trinity Environmental Group and ATC investigations
• Limitations for development
Intersection of 13th and Hulman Streets
September 2004
Future Direction
• Finish Phase II review & GIS mapping
• IDEM response letter & proposed additional testing
• Remediation plans
• Potential development scenarios
Phase II Review & GIS Mapping
• Soil borings and analytical testing
• Location of contaminants
• Contamination density mapping (GIS)
• Brownfield research
• Federal, state, and local development requirements
• Grant availability
IDEM Response Letter & Proposed Additional Testing
• Inadequacies of initial testing• What tests need to be conducted again?
• What tests have never completed that are needed?
• How much extra will this cost?
Remediation Plans
• Specific areas or entire site
• Closure levels
• Worst-case scenario
• Plan based on current contaminant knowledge
• Cost analysis of two options
