Slide21 l.jpg

Certification Conference

  • PAL > Analyses > Report > FEMA

  • 2 yr. max.

  • Monroe, Itawamba, Tishomingo counties

  • 31 August deadline to sign request or decline to seek accreditation


Slide25 l.jpg

  • Required report Submittals

    • Engineering Analyses

    • Operations and Maintenance Plans

    • As-Builts

    • Stamped by Engineer

    • USACE requirements more comprehensive and exhaustive


Slide26 l.jpg

Issue Conference

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 . . .


Slide27 l.jpg

Issue Conference

Certification – no analyses exist that refute or demonstrate flood control performance; required analyses are extensive.

Hydraulics, geotechnical, vegetation compliance, O&M . . .


Slide29 l.jpg

Issue Conference

Vegetation – currently heavily wooded, can not certify unless vegetation and roots removed.

Would also require increased annual O&M to sustain levee requirements. . .




Slide33 l.jpg

Issue Conference

Wildlife Mitigation – Wooded areas on levee are part of Tenn-Tom mitigation lands.

Clearing would likely require acquisition of replacement lands. . .
