8. Progress to Date Development Envelope Topographic Survey Low Impact Development (LID) Codes and Regulations Subsurface Conditions Begin Phase II Review Int. of 13 th Street and Lockport Road September 2004

9. Development Envelope Availability and location of utilities Floodplains, wetlands and underground mines Right-of-way Zoning restrictions Soil contamination Holey Moley 800-382-5544

10. Topographic Survey Rough topographic survey completed Obtained complete survey performed by American Consulting Inc. Compared two surveys to ensure accuracy

11. Topographic Survey

12. Low Impact Development Bioretention considerations Vegetated swales Pervious pavements Cisterns Cost analysis

13. 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

14. Subsurface Conditions Preliminary geological investigation Compared with soil borings from Trinity Environmental Group and ATC investigations Limitations for development Intersection of 13 th and Hulman Streets September 2004

15. Future Direction Finish Phase II review & GIS mapping IDEM response letter & proposed additional testing Remediation plans Potential development scenarios

16. 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

17. 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?

18. Remediation Plans Specific areas or entire site Closure levels Worst-case scenario Plan based on current contaminant knowledge Cost analysis of two options

19. Potential Development Scenarios Site layout Phasing of project Roadway design Phase I Phase II Phase III Phase IV
