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

Topographic Survey

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

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
