Defining ULOP in Local Plans of Flood Protection for Urban Floodzones Thomas S. Plummer P.E., CFM
“Urban level of flood protection” means the level of flood protection that is necessary to withstand flooding 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 (California Government Code 65007(1)). • Topics: • Acronyms and Definitions • Draft Urban Level of Flood Protection (ULOP) • CVFPP / Regional Plans / Local Plans • What is a Local Plan of Flood Protection (LPoFP)
Acronyms and Definitions • ULOP = Urban Level of Protection • PoFP (PFP) = Plan of Flood Protection • LPoFP (LPFP) = Local Plan of Flood Protection • ULE = Urban Levee Evaluation • NULE = Non Urban Levee Evaluation • CEQA = California Environmental Quality Act • FEMA = Federal Emergency Management Agency
Acronyms and Definitions • DWR = California Department of Water Resources • SPFC = State Plan of Flood Control • ULDC = Urban Levee Design Criteria • CVFPP = Central Valley Flood Protection Plan • SB5 = 1997/1998 Senate Bill 5 and associated legislation. • SB-1278 = 2012 Senate Bill 1278 (signed?)
Acronyms and Definitions (d) “Flood hazard zone” means an area subject to flooding that is 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. SHADED ZONE X (500) & ALL ZONE A’s & V’s DISCLAIMER
Acronyms and Definitions (e) “National Federal Emergency Management Agency standard of flood protection” means the level of flood protection that is necessary to withstand flooding that has a 1-in-100 chance of occurring in any given year using criteria developed by the Federal Emergency Management Agency for application in the National Flood Insurance Program. 100-YR FLOOD
Acronyms and Definitions (f) “Non-urbanized area” means a developed area or an area outside a developed area in which there are fewer than 10,000 residents that is not an urbanizing area. (l) “Urban area” means a developed area in which there are 10,000 residents or more. (m) “Urbanizing area” means a developed area or an area outside a developed area that is planned or anticipated to have 10,000 residents or more within the next 10 years.
Acronyms and Definitions (h) “Sacramento-San Joaquin Valley” means lands in the bed or along or near the banks of the Sacramento River or San Joaquin River, or their tributaries or connected therewith, or upon any land adjacent thereto, or within the overflow basins thereof, or upon land susceptible to overflow therefrom. The Sacramento-San Joaquin Valley does not include lands lying within the Tulare Lake basin, including the Kings River.
Acronyms and Definitions (k) “Undetermined risk area” means an urban or urbanizing area within a moderate flood hazard zone, as delineated on an official flood insurance rate map issued by the Federal Emergency Management Agency, which has not been determined to have an urban level of protection. Area of concern which doesn’t meet the ULOP
Acronyms and Definitions 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.
Acronyms and Definitions 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.

Regional Plans – Lower Sacramento How do we connect Upland Area Plans of Flood Protection to Regional Plans?
Local Plans of Flood Protection 3.1 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 andcostsof 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 Protection • The 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 CVFPPto 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.
