  10. Extra Slides for Reference

  11. What is the JFP? • A new auxiliary spillway adjacent to the main dam, including: • approach channel • control structure • spillway chute • stilling basin • Improves the ability to manage large flood events by lowering the spillway elevation to allow more water to be released earlier in a flood event.

  12. Background JFP will work in conjunction with upgraded levees downstream to achieve a 200-year level of protection.

  13. Background Schedule History • Original schedule – 2015 completion • 35% design • accepted as baseline schedule • Revised schedule – 2018 completion • More detailed design • Reviewed & recommended by consultants • Unsatisfactory to all parties • Joint task force revised schedule – 2017 completion

  14. Commitments • October 2017 completion: Optimal Completion Date • Aggressive • Realistic • Weighs risks and rewards developed by Task Force • The USACE will continue to seek opportunities to accelerate the schedule
