PL23063301 – U.S. Army Corps of Engineers (USACE) Public Law 84-99 Emergency Repair of Maintenance Area 13 Unit 2 South - Cherokee Canal Left Bank Levee System

Project PL23063301 is an emergency repair effort managed by the U.S. Army Corps of Engineers Sacramento District and the Central Valley Flood Protection Board to restore the Cherokee Canal Left Bank Levee System at Site 0633-01 in Butte County, California. The work is statutorily exempt from CEQA under emergency and ministerial provisions following a Governor-proclaimed state of emergency regarding storm damage from early 2023. The primary objective is to return the levee to pre-flood conditions through specific engineering interventions, including excavating at a 1H:1V slope and reconstructing to a 2H:1V slope using appropriate levee fill material. The technical scope includes the installation of a keyway measuring 3 feet deep and 8 feet wide for enhanced protection, with material benched into the existing structure to ensure a secure interface. Critical performance requirements include precise compaction of the roadway crest to prevent water infiltration and the formation of tension cracks along the edge. The project is located approximately 10 miles west of Gridley at Levee Mile 22.9. Primary points of contact for the effort include Jennifer Calles of the Central Valley Flood Protection Board and Jonathan Yau of the USACE Readiness Branch.
