Hundreds of levee sites have been identified for repair throughout the Central Valley. These repair sites are
not improvements, but are sites that require immediate attention to maintain operation of Central Valley flood
control systems. These repairs are necessary to maintain the functionality of flood control systems that have
deteriorated over time and/or do not meet current design standards. While many of the most urgent repairs have
been completed or are near completion, other sites of lower priority are still in progress, and still more are
in the process of being identified, planned, and prioritized.
The Levee Repairs Program repairs critically damaged levees and proactively repairs other damaged levees that
cannot wait for system improvement projects and require rapid repair before the next flood season. Levee repair
projects are implemented through collaboration with federal and state resource agencies, USACE, and local agencies.
Levee repairs are done under three federal authorized programs; Sacramento River Bank Protection Project (SRBPP),
Levee Stability Program (LSP), and PL84-99 Rehabilitation Assistance Program (PL84-99). In addition, the State
repairs flood project levees under the Sacramento-San Joaquin Erosion Repairs Project (SSJERP).
- Leverage local and federal funding and maximize funding to repair the maximum number of sites with available
Bond 1E funding.
- Repair critical sites before the ensuing high water event and prioritize remaining sites based on severity
of damage and consequences of failure.
- To the extent practical, ensure that repairs fit into long-term strategies, including the legal mandate of
200-year flood protection for urban areas.
DWR is the lead agency for the Sacramento-San Joaquin Erosion Repairs Program, while the
United States Army Corps of Engineers (USACE)
is the lead agency for the Sacramento River Bank Protection Project and the PL 84-99 Rehabilitation Program.
("PL 84-99" refers to federal Public Law 84-99, the Flood and Coastal Storm Emergencies Act), and the
Calfed Levee Stability Program.
There are essential differences between the types of repair sites referenced on these pages. "Critical
Erosion Repair sites" are the highest-priority erosion sites where levee degradation has occurred to the
extent that they are at risk of failure even during normal flow conditions.
"PL 84-99" sites, on the other hand, are levee rehabilitation efforts in response to damage from
specific flood events. Under federal statute, USACE and DWR are authorized to conduct emergency repairs to flood
management works threatened or destroyed by high-water events, such as California's 1997 and 2006 floods. PL 84-99
sites are prioritized by "order" of urgency, ranging from the most urban Order 1 sites through the most
rural Order 5 sites.
DWR is also working with local agencies to survey and document erosion damage at additional sites that are under
local control (not part of the State/federal flood control system), with the aim of assisting local jurisdictions in
determining the best approach for needed repairs. Local maintaining agencies can participate in the
Local Levee Grant Program with State/local
cost-sharing divided evenly, provided the repair sites are deemed critical by DWR.
