2 Presentation Agenda Facility History Inspections & Studies Rehabilitation vs. Replacement Design of New Small Lock New Lock Video Production Estimate of Probable Costs 2004 Escalation Factors 2004 to 2015 Estimate of Probable Costs 2015 Current Lock Status Questions Existing 84 x 660 Lock New Small 40 x 164 Lock

3 Inglis Facility History Constructed Lock, Main Spillway, By-pass Channel & Bypass Spillway in Mid 1960 s as Part of Cross-Florida Barge Canal [USACE] C-F BC to Connect Waterway Passage across Florida 1971 Construction Stopped Environmental Concerns 1991 Project De-authorized by USACE and Became Part of State of Florida Recreation [FDEP/OG&T] Used by Small Recreational Traffic to/from Lake Rousseau Also used by USCG for Safe Port During Storm Events

4 Inglis Facility History 1999 Lock Closed to Vessel / Boat Usage Concerns over Miter Gate Safety Concerns over Manatee Injuries and Deaths Around 2008 Upstream Bulkheads Installed Lock & Gates Inspected Since Then Planned 2015 Inspections by FDEP

5 Facility Inspections & Studies Periodic Inspection & Material Condition Survey: Lock & Spillways 2 Part Study in Late 2001 & Early 2002: Bergmann & URS Corp. (Tampa) Comparison Between Full Lock Rehabilitation and Construction of a New Small Lock Inside Existing Lock 84 x 660 Existing Lock Chamber with Approach Walls 40 x 164 New Lock Chamber Utilizing Existing Upper Sill Evaluation of Lock Usage as Auxiliary Floodway Continued Inspection of Critical Miter Gate Members During Closure Period (Yearly)

6 Lock Rehabilitation vs. Small Lock Replacement Advantages of Lock Rehab Alternative [84 x 660 ] Lower Initial Cost Can Phase Rehab to Suite Variable Funding Streams Facility & Systems Familiar to Current Operators Unlimited Vessel Size Utilization Limited Environmental & Site Impacts Shorter Construction Schedule & Activity

7 Lock Rehabilitation vs. Small Lock Replacement Advantages of New Small Lock [40 x 164 ] Anticipated Lower Life-Cycle Cost [Lower O&M Costs] Greatly Reduced Fresh Water Utilization [Loss] Full 50-Year Life Expectancy [vs. 20 Years for Rehab] Practical Vessel Size Utilization [USCG Vessel & Barges] Possible Spillway Addition Easier Manatee Protection

8 Design of New Small Lock Following 2002 Decision by the FDEP Full Contract Plans, Specifications, Design Report & Cost Estimate Design Features: Construction of Lock Mostly in the Dry (Existing Lock Chamber) New Lower Gate Monoliths & Sill Balance of Existing Lock to Act as Approach Walls RCC for New South Lock Wall Efficient Piping and Valve F&E System Manatee Protection Systems (Lock Gates, Ports & Spillways) PLC Control Systems Gate Cathodic Protection Roughly 95%Complete
