  18. QUESTIONS?

  19. Tennessee-Tombigbee WaterwayCanal Section Levee Certification 20 August 2009

  20. Certification • PAL > Analyses > Report > FEMA • 2 yr. max. • Monroe, Itawamba, Tishomingo counties • 31 August deadline to sign request or decline to seek accreditation

  21. Certification Requirements • 44 CFR 65.10 and complementary USACE and FEMA regs • Required report Submittals • Engineering Analyses • Operations and Maintenance Plans • As-Builts • Stamped by Engineer • USACE requirements more comprehensive and exhaustive

  22. Issue Authority – Public Law 79-525, 79th Congress, 2d Session, enacted July 24, 1946. Two-way barge traffic, no provisions in the authorization for flood control protection . . .

  23. Issue Certification – no analyses exist that refute or demonstrate flood control performance; required analyses are extensive. Hydraulics, geotechnical, vegetation compliance, O&M . . .

  24. Issue Vegetation – currently heavily wooded, can not certify unless vegetation and roots removed. Would also require increased annual O&M to sustain levee requirements. . .

  25. Vegetation Requirement, ‘Overbuilt’

  26. Vegetation Requirement, ‘Typical’

  27. Issue Wildlife Mitigation – Wooded areas on levee are part of Tenn-Tom mitigation lands. Clearing would likely require acquisition of replacement lands. . .
