Reflecting Governor Arnold Schwarzenegger's long-term commitment to improving flood safety
to prevent possible catastrophic flooding and loss of life, DWR is undertaking unprecedented efforts
to evaluate and upgrade aging and deteriorating levees along the Sacramento and San Joaquin River Valleys
and Delta. Of highest priority, DWR is fully evaluating more than 300 miles of urban project levees in
these areas, with plans to later survey the entire 1,600 miles of project levees in the Central Valley.
Funding for the levee evaluation efforts is provided through two large flood control bonds approved by
California voters in November 2006, Propositions 84 and 1E.
 Geotechnical subsurface
investigations (drilling to collect core soil samples and cone penetration tests) are underway along
levees in the Woodland area. For more information, go to
Geotechnical Evaluations.
To expedite efforts to protect these communities, levee evaluations are being conducted in a fast-track manner over a two- to three-year period. During this time, technical specialists are reviewing existing levee historical data; mapping near-surface geology; conducting field explorations; performing engineering, stability and seepage analyses; and preparing preliminary design and construction estimates for repairing and upgrading the levees, where needed.

As an essential first step in providing improved flood protection for communities
in the Central Valley, DWR is conducting geotechnical exploration, testing, and analysis of state and
federal levees that protect the highly populated urban areas of greater Sacramento, Stockton/Lathrop, and
Marysville/Yuba City. This program is being implemented simultaneously with the various urgent levee repairs.
