California Drought Contingency PlanFlood Risk ManagementFlood Risk Management is a strategy specifically intended to enhance flood protection.This strategy includes projects and programs that assist individuals and communities tomanage floodflows and to prepare for, respond to, and recover from a flood. Thisstrategy is a key element of integrated flood management, a process that promotes acomprehensive approach that considers land and water resources at a watershed scalewithin the context of integrated regional water management. The aim of this strategy isto maximize the benefits of floodplains, minimize the loss of life and damage to propertyfrom flooding, and recognize the benefits to ecosystems from periodic flood events.This resource management strategy recognizes the potential benefits to water supplyand drought preparedness. Detention of floodwaters with both structural and nonstructural methods could provide benefits to the extent that they result in additionalwater storage or groundwater infiltration and increased protection of water supplyconveyance systems.Land Use Planning & ManagementIntegrating land use and water management consists of planning for the housing andeconomic development needs of a growing population while providing for the efficientuse of water, water quality, energy, and other resources. The way in which we useland—the pattern and type of land use and transportation and the level of developmentintensity—has a direct relationship to water supply and quality, flood management, andother water issues.Land use resource management strategy brings together many concepts which ifadopted together will make existing and future land development more efficient in use ofwater and hence makes communities more sustainable and resilient to the effects ofdrought.Recharge Area ProtectionRecharge areas are those areas that provide the primary means of replenishinggroundwater. Good natural recharge areas are those where good quality surface wateris able to percolate unimpeded to groundwater. If recharge areas cease functioningproperly, there may not be sufficient groundwater for storage or use. Protection ofrecharge areas requires a number of actions based on two primary goals. These goalsare (1) ensuring that areas suitable for recharge continue to be capable of adequaterecharge rather than covered by urban infrastructure, such as buildings and roads; and,(2) preventing pollutants from entering groundwater in order to avoid expensivetreatment that may be needed prior to potable, agricultural, or industrial beneficial uses.The primary benefit of protecting recharge areas is that those recharge areas can beused by water managers to store water in aquifers as part of a program to provide asustainable and reliable water supply of good quality, thereby reducing impacts due todrought.14
California Drought Contingency PlanRecycled Municipal WaterIn 2009, DWR developed dual plumbing standards, in consultation with the CaliforniaDepartment of Public Health and other agencies, to safely plumb certain buildings andcommercial properties with both potable and recycled water systems. On November 18,2009, the Building Standards Commission unanimously voted to approve the CaliforniaDual Plumbing Code and building codes were codified in January 2010. The code waspublished on July 4, 2010 which began the statutory 180-day period between publishingand the effective date of the code. The Dual Plumbing Code effective date is January11, 2011.In May 2009, the State Water Resources Control Board adopted the Recycled WaterPolicy (Recycled Policy) which is intended to support their Strategic Plan priority ofpromoting sustainable local water supplies. Increasing the acceptance and promotingthe use of recycled water is a means towards achieving sustainable local water suppliesand can result in reduction in greenhouse gases by reducing some of the need forimported water, a significant driver of climate change. The Recycled Policy is alsointended to encourage beneficial use of, rather than solely disposal of, recycled water.To the extent water recycling provides additional water supply it provides additionalresilience to drought.In July 2009, the State Water Resources Control Board adopted General WasteDischarge Requirements for Landscape Irrigation Uses of Municipal Recycled Water(General Permit). The Landscape General Permit is consistent with the HRecycled WaterPolicyH, State and Federal water quality laws, including the statewide water qualitystandards established by the California Department of Public Health. The GeneralPermit facilitates the streamlining of the permitting process to reduce the overall costsnormally incurred by producer, distributors, and users of recycled water.See website (www.water.ca.gov/recycling/) for more information on the water recyclingand the California Water Plan Update 2009, Volume 2, Chapter 11 Recycled WaterManagement Resource Management Strategy.Surface Storage – CALFEDThe CALFED Record of Decision (2000) identified five potential surface storagereservoirs that are being investigated by the California Department of Water Resources,US Bureau of Reclamation, and local water interests.• Shasta Lake Water Resources Investigation (SLWRI)• North-of-the-Delta Offstream Storage (NODOS)• In-Delta Storage Project (IDSP)• Los Vaqueros Reservoir Expansion (LVE)• Upper San Joaquin River Basin Storage Investigation (USJRBSI)California’s water resources future has become increasingly uncertain. Consequently,these proposed projects would need to perform well under a number of potential future15
