Document Description
A series of storms struck Northern California and Nevada in late December and early January 2005/2006. The Sacramento River and associated tributaries reached flood stage. High flows, high tides, and high winds were experienced in the Sacramento-San Joaquin Delta. A Federal Disaster Declaration was issued for 31 California counties due to floods, mudslides, and landslides caused by the storms.
The project site is located within the Lower San Joaquin Reclamation District in Madera County. The site is located along the western bank of the Chowchilla Canal, approximately 4.5 miles northeast of the City of Mendota, and protects an agricultural area near the City of Firebaugh. The area of erosion is approximately 100 by 40 feet. Total project footprint is approximately 1.5 acres.
The repairs for this levee site would consist of restoring the original level of protection by reconstructing the levee embankment to the pre-flood slope and height and by restoring the rock protection on the levee slope. Debris deposited by the flood fight on the eroded slopes and rockfill material placed by the Lower San Joaquin Levee District (LSJLD) during the flood fight will be removed and stockpiled in order to complete the repairs. A layer of compacted impervious fill will be constructed on the waterside slope to prevent seepage through the levee, and the levee crown will be built up using compacted aggregate-base course material. The stockpiled rockfill will be placed landside of the levee toe creating a berm-blanket.

Reasons for Exemption
As a result of the imminent threat of catastrophic levee failure, Governor Arnold Schwarzenegger proclaimed a state of emergency for California's levee system in February 2006. In that emergency proclamation, and in the Governor's Executive Order S-01-06 issued in March 2006, the Governor directed DWR to continue to identify additional levee sites that may require expedited repairs in order to prevent a catastrophic failure. Recent investigations by DWR and the U.S. Army Corps of Engineers have identified numerous additional levee sites throughout the State which are in a substantially degraded condition and in need of immediate emergency repairs. On October 3, 2006, the Governor issued Executive Order S-18-06, which found that conditions of extreme peril to the safety of persons and property continue to exist along California's levees and other flood control systems. The emergency repairs for this project are necessary to maintain the levee system, which is essential to protecting the public health, safety, and welfare, and to avoid a catastrophic levee failure.
