USACE Planning Requirements for GRR
• USACE identifies National Economic Development (NED) Plan
• Non-federal sponsors identify LPP
• If LPP deviates from NED, LPP waiver may be required

Proposed NEDNED Plan elements:
• Address seepage & stability
• Implement extensive erosion protection programs
• Raise levees
• Remove vegetation from upper 2/3 of levee
• Acquire landside access along Sacramento River and Arcade Creek
![Page 10: American River Common Features General Re-evaluation Report Request for Board Approval of](https://reader035.vdocuments.net/reader035/viewer/2022070423/568166d8550346895ddaf4c7/html5/thumbnails/10.jpg)
Proposed LPPLPP differences from NED:
• Address seepage and stability issues first
• Significantly less erosion remediation
• Levee raises
• Widen the Sacramento Bypass & Weir
• Systemwide Improvement Framework (SWIF) for low risk vegetation, encroachments, and landside access issues
