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 . . .

slide27

Issue

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

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

slide29

Issue

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

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

slide33

Issue

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

Clearing would likely require acquisition of replacement lands. . .
