DWR 2006 Critical Levee Emergency Repair Project - Site 20060404-007-001 (RD-1602)
Document Type
NOE - Notice of Exemption
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 site is approximately 300 feet long. The repair consists of the construction of a 80-feet wide under seepage berm. The berm will be constructed of drain rock placed on a filter layer of concrete aggregate, will be 5 feet thick above the levee toe, and will slope down to 3 feet at the berm toe. The berm will be covered by a 12-inch thick layer of topsoil. Geotextile will be placed between the drain rock and the topsoil to prevent migration of the topsoil into the drain rock. The under seepage berm will be extended 200 feet along the levee toe.

Type, Section or Code
Section 15269(b)(c)
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. On November 2, 2006, the Army Corps of Engineers, Sacramento District, issued a Declaration of Emergency for 24 newly identified critical levee sites along the Sacramento and Bear rivers, Cache Creek, Steamboat Slough, and Sutter Slough. DWR and Corps have determined that all of these 24 sites, including the project site, are severely damaged, pose an imminent threat of levee failure, and are in need of emergency repairs. 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.
