June 13, 2013 — Draft Regional Flood Atlases released for six regions along the Sacramento and San Joaquin Rivers

Draft Regional Flood Atlases have been developed for the six planning regions as part of the Regional Flood Management Planning effort. These atlases show flood risk characteristics and hazards for each region, as well as Local Maintaining Agencies, flood control facilities, general land use, managed environmental lands, and more. Each atlas was compiled from existing data to share understanding and to facilitate discussions about the current state of flood risks.

The California Department of Water Resources (DWR) has launched the Regional Flood Management Planning effort to assist local agencies to develop long-term regional flood management plans that address local needs, articulate local and regional flood management priorities, and establish the common vision of regional partners. DWR will provide funding and resource support to help develop regional plans consistent with the 2012 Central Valley Flood Protection Plan (CVFPP).

What are the planning regions?

Though the 2012 CVFPP identifies nine regions (Upper Sacramento, Mid-Sacramento, Feather River, Lower Sacramento, Delta-North, Delta-South, Lower San Joaquin, Mid-San Joaquin, and Upper San Joaquin), some regions have partnered together, resulting in six regions. These six regions are the Upper/Mid-Sacramento River, Feather River, Lower Sacramento River/Delta North, Lower San Joaquin River/Delta South, Mid-San Joaquin River, and Upper San Joaquin River.

Each of the six planning regions has formed a working group that is led by a local agency and consists of representatives from flood management agencies, land use agencies, flood emergency responders, permitting agencies, and environmental and agricultural interests. The regional plans will present local agencies' perspectives of flood management with a prioritized list of projects that need to be implemented to reduce flood risks in each region. Each plan will also present an assessment of the proposed project costs and benefits, considering the projects’ potential contributions to an integrated multi-benefit and basin-wide solution.

How will the plans be developed?

The planning regions will use available information and conduct technical work to develop a plan through interaction, coordination, and collaboration among all parties that reflects the participating entities' vision for flood management in the region. At minimum, each regional plan will include:

  1. An informational atlas describing the regional setting and available information.
  2. A vision of integrated flood management for the region.
  3. A financial plan that includes local funding strategies and considers the financial feasibility of the proposed actions.
  4. An assessment of the regional flood risks and management actions or projects needed to reduce flood risks.
  5. Discussion of regional priorities, how projects are prioritized, and what criteria have been used for prioritization.
  6. A prioritized list of potential local or regional projects.
  7. Project descriptions and their costs.
  8. Project beneficiaries, regional benefits, and systemwide benefits.
  9. A description of regional governance for project implementation.
  10. An assessment of the regional operations and maintenance (O&M) and flood emergency response issues and how they will be addressed.

Who should get involved?

The regional flood management planning partners are developing and implementing communication strategies to engage and brief broader interest groups on flood management planning in the region. The planning process may include participation from:

  • Regional flood and water management agencies
  • Land use agencies, such as cities and counties
  • Agricultural interests
  • Environmental interests
  • Permitting or resource agencies
  • Local emergency responders
  • Tribes
  • Recreational interests

How do I get involved?

Any interested parties should contact their region’s lead agency to participate in this locally led process. Please see our Regional Contacts page for more information.

What role will DWR play in Regional Planning?

DWR will participate in the planning process as requested by the regional agencies, exchange planning information, provide technical information, and financial assistance through a directed funding program. The level of DWR's involvement may vary depending on the region and the availability of resources at the local level and their desire to have DWR involved. When the regional plans are completed, DWR will incorporate feasible components of the regional plans in the 2017 Central Valley Flood Protection Plan (CVFPP) Update that are consistent with the State Systemwide Investment Approach as defined in 2012 CVFPP.
