(d) “Flood hazard zone” means an area subject to flooding thatis delineated as either a special hazard area or an area of moderate hazard on an official flood insurance rate map issued by the Federal Emergency Management Agency.

The identification of flood hazard zones does not imply that areas outside the flood hazard zones, or uses permitted within flood hazard zones, will be free from flooding or flood damage.

ULOP


From SB-1278:

ULOP(n) “Urban level of flood protection” means the level of protection that is necessary to withstand flooding from a leveed riverine system that has a 1-in-200 chance of occurring in any given year using criteria consistent with, or developed by, the Department of Water Resources.

“Urban level of flood protection” shall not mean shallow flooding or flooding from local drainage that meets the criteria of the national Federal Emergency Management Agency standard of flood protection.


From AB-1965:

ULOP(n) “Urban level of flood protection” means the level of protection that is necessary to withstand flooding from a leveed riverine system that has a 1-in-200 chance of occurring in any given year using criteria consistent with, or developed by, the Department of Water Resources.

“Urban level of flood protection” shall not mean shallow flooding or flooding from local drainage that meets the criteria of the national Federal Emergency Management Agency standard of flood protection.

Local Plans of Flood Protection3.1 Water Code Sections 8200 and 8201 3.1.1 Local Flood Protection Planning Act/Local Plan of Flood Protection

The 2007 flood risk management legislation enacted the Local Flood Protection Planning Act of 2008. This Act allows, but does not require, a local agency to prepare a local plan of flood protection (Water Code Section 8200 and 8201).

Local Agencies May…A local agency may prepare a local plan of flood protection, which will include all of the following: 1. “A strategy to meet the urban level of flood protection, including planning for residual flood risk and system resiliency. 2. Identification of all types of flood hazards. 3. Identification and risk assessment of the various facilities that provide flood protection for flood hazard areas, for current and future land uses. 4. Identification of current and future flood corridors. 5. Identification of needed improvements and costs of those improvements to the flood protection facilities that are necessary to meet flood protection standards.6. An emergency response and evacuation plan for flood-prone areas. 7. A strategy to achieve multiple benefits, including flood protection, groundwater recharge, ecosystem health, and reduced maintenance costs over the long term. 8. A long-term funding strategy for improvement and ongoing maintenance and operation of flood protection facilities” (Water Code Section 8201).

Local Plans of Flood ProtectionThe process of preparing a local plan of flood control is anticipated to be completed by flood agencies and/or local reclamation districts, as these agencies and districts are most responsible for flood protection. However, cities and counties that have planning areas that are affected should consult with the applicable agency and/or district and be involved in the final approval of the plan.

Local Agencies Should Consider…•Preparing a local plan of flood protection, although not mandatory (LPoFP). •Participating in the development of the CVFPP to facilitate consistency in subsequent development of a local plan of flood protection. •Coordinating closely with local flood agencies and reclamation districts when preparing a local plan of flood protection. Local Agencies Can Comply By…

•A local plan of flood protection, if prepared, should be consistent with the CVFPP (required to be adopted by July 1, 2012).

Obtain More Information Here…Once the CVFPP is adopted (required by July 1, 2012), additional information and direction will be available. Contact DWR’s Division of Flood Management at http://www.water.ca.gov/floodmgmt/ with questions regarding the voluntary preparation of a local plan of flood protection.
