3 PRE-CAWS

4 CAWS YESTERDAY

5 CAWS

6 CAWS TODAY Still a working river

7 PURPOSE & GOALS Purpose: o Identify and evaluate options for physical separation Goals: o Prevent the transfer of aquatic invasive species via the CAWS o Improve flood management o Improve water quality o Improve transportation (i.e., movement of goods, materials and people) o Inform and coordinate with GLMRIS

8 Asian Carp Round Goby Spiny Water Flea Zebra Mussels Invasive species are a major risk to both Great Lakes and Mississippi River ecosystems?

9 WHAT ARE THE CHALLENGES OF THE STUDY? Flood Management Ecology Transportation Recreation Operating Doctrine

10 EXISTING CONDITIONS: Water Quality

11 TRANSPORTATION CHALLENGES Waterway Traffic o Recreational o Commercial o Industrial

12 EXISTING CONDITIONS: Cargo Movements

13 DIVERSE PERSPECTIVES Great Lakes Mississippi Separation Technologies Regulatory Social/Political Environmental Industry Cost/Benefit

14 STAKEHOLDERS Federal Agencies o USACE o EPA o Tribes State Agencies o IL DNR (example) o Basin Governors and Mayors Local Agencies o MWRDGC o City of Chicago Private Industry NGOs (GLC project sponsor)

15 STUDY OBJECTIVES Establish baseline conditions Provide at least three options for physical separation Estimate economic cost and benefits Provide summarized document

16 BASELINE CONDITIONS Area Current and Planned Anticipated Emerging AIS Control Issues Continuation of ongoing programs and efforts for implementing AIS control measures Flood Management TARP completed Green infrastructure (existing programs/ordinances) USACE and MWRDGC flood control projects Improved local/regional conveyance to TARP N/A Water Quality Disinfection at North Side and Calumet WWTPs Disinfection at Stickney WWTP Nutrient removal at North Side, Calumet, and Stickney WWTPs Constituents not currently regulated for WWTPs Remediation of contaminated sediments Transportation Panama Canal expansion Chicago Park District harbor improvements Programmed road improvements CREATE Rail Chicago-St. Louis High Speed Rail GoTo2040 Regional Projects Illiana Expressway N/A

17 ALTERNATIVE EVALUATION Barrier Locations Associated Infrastructure Improvements o Flood Management o Water Quality o Transportation Timeline for Implementation o Improvements required prior to barrier installation o Dependencies (e.g. TARP) Economic Analysis o Incremental costs to existing commitments o Long-term qualitative beneficial return on investments

21 Lake Michigan DOWN RIVER ALTERNATIVE City of Chicago Flood Management o Significant flow management Water Quality o Significant WWTP upgrades Transportation o Distant from industries

22 DOWN RIVER ALTERNATIVES Flood Management o Significant Flow Management Water Quality o Significant WWTP Upgrades Transportation o Distant from industries

23 City of Chicago Lake Michigan MID SYSTEM ALTERNATIVE Flood Management o Least investment Water Quality o Northside WWTP upgrades Transportation o Chicago - limited impact o Calumet - multimodal port

24 City of Chicago Lake Michigan NEAR LAKE ALTERNATIVE Flood Management o Significant flow management Water Quality o Limited requirements Transportation o Significant port and use impacts
