Flooding is a major issue across California – every county has experienced a federally declared flood disaster in the past 20 years. To help Californians stay prepared this flood season, DWR is participating in the eighth annual California Flood Preparedness Week from October 19 – 26, 2019.
We operate and maintain federally constructed flood control features in the Central Valley. We cooperate with the U.S. Army Corps of Engineers to repair flood-damaged federal flood control projects maintained under the authority of the Central Valley Flood Protection Board, which include levees, channels, and various flood control structures. To maintain the system, we plan, inspect, coordinate and permit environmental work, and design and construct repairs.
We also inspect levees within the State Plan of Flood Control (SPFC) to ensure maintenance and management obligations are met. We work with local levee maintaining agencies to meet Public Law 84-99 (PL 84-99) compliance standards.
In addition to our inspections, we repair and rehabilitate SPFC levees and flood control facilities. Through various state and federal programs such as the Sacramento River Bank Protection Project, Flood System Repair Project and PL 84-99, we work with other state, federal and local interests to inspect, evaluate, permit, design, and construct repairs for levee deficiencies that fall outside of routine maintenance.
When maintaining channels, levees, and flood control structures, we comply with state and federal environmental laws and regulations, including:
- California Environmental Quality Act
- California Endangered Species Act
- Federal Endangered Species Act
- Federal Clean Water Act
We are incorporating the 2017 Central Valley Flood Protection Plan Update's Conservation Strategy in our work, while streamlining permitting processes and coordinating with the regulatory agencies involved in all flood maintenance activities.
DWR is completing the second year of the Elder Creek Channel Rehabilitation Project. The five-year project will clear sedimentation and vegetation to restore flow capacity of a four-mile stretch of the state-maintained Elder Creek in Tehama County.
DWR announced $4.9 million of Proposition 1E and $5 million of Proposition 1 funding is available in Fiscal Year 2019-20 for Directed Funding action under the Delta Flood Emergency Response Grant Program, Round 2 Guidelines.
Many of us are familiar with the category system that ranks the severity of hurricanes and tornadoes. A similar system is now being rolled out for atmospheric rivers (AR) -- those long, transient corridors of water vapor that fuel major rain events each winter in the west, especially California.
DWR released the draft Regional Flood Management Assistance Program (RFMAP) Guidelines for a 45-day public comment period.
The Flood Maintenance Assistance Program (FMAP) is a new program that provides State funds for eligible maintenance activities to Local Maintaining Agencies (LMAs) and Maintenance Areas (MAs).
The Central Valley Tributaries Program is soliciting grant proposals for multi-benefit flood risk reduction projects.
After this historic year of fires, it is more important than ever that Californians are aware of their flood risks if they live downhill of areas affected by wildfires.
The Delta Levees Maintenance Subventions Program has released Addendum 1 to its Program Guidelines for a 30-day comment period.
California is known for its variable climate. Climate change will only exacerbate this variability, so water managers are eyeing a way to capitalize on the extremes by harnessing flood waters and redirecting them into parched aquifers.
