                   ASSEMBLY COMMITTEE ON WATER, PARKS AND WILDLIFE
                            Jared William Huffman, Chair
                    AB 2304 (Huffman) - As Amended:  April 6, 2010
           
          SUBJECT  :   Groundwater management plans

           SUMMARY  :   Adds protection of priority groundwater recharge  
          areas to the components which may be included in groundwater  
          management plans.  Specifically,  this bill:

            1) Defines prime groundwater recharge areas as areas where the  
             surface topography, subsurface geologic composition and  
             structures, and rates of water infiltration render the area a  
             principal contributor to the replenishment of the groundwater  
             basin, either under natural conditions, artificially  
             augmented groundwater recharge, or both.

           2) Requires a public water system with 3,000 or more service  
             connections to provide a city or county which is proposing to  
             adopt or substantially amend a general plan with a  
             description of prime recharge areas, as appropriate and  
             relevant.

           3) Requires a local agency to include a map of prime recharge  
             areas in its groundwater management plan and an  
             identification of any potential threats to the capability of  
             the prime recharge areas to continue to replenish  
             high-quality groundwater due to future changes in land use,  
             urban development, or instream flow modifications.

           4) Allows a local agency to include, as a groundwater  
             management plan component, coordination with local planning  
             agencies to develop and implement land use strategies that  
             protect prime recharge areas.

           EXISTING LAW  :

          1)Encourages local agencies to work cooperatively to manage  
            groundwater resources within their jurisdictions and, if not  
            otherwise required by law, to voluntarily adopt groundwater  
            management plans.

          2)Requires a groundwater plan contain components related to  








                                                                  AB 2304
                                                                  Page  2

            funding, management, and monitoring in order for a local  
            agency to be eligible for groundwater project funds  
            administered by the Department of Water Resources (DWR).

          3)Allows a groundwater plan to voluntarily contain additional  
            listed components.

          4)Requires all of the groundwater basins identified in DWR's  
            Bulletin 118 to be regularly and systematically monitored and  
            the information to be readily and widely available.

          5)Makes entities managing groundwater, including local agencies  
            that are monitoring groundwater pursuant to a groundwater  
            management plan, eligible for state water grants and loans.  

           FISCAL EFFECT  :   Nonfiscal

           COMMENTS  :   Groundwater is one of California's most important  
          natural resources and our reliance on it continues to grow.   
          Periodically, DWR produces a report on California's groundwater  
          entitled Bulletin 118.  In the most recent version of Bulletin  
          118, produced in 2003, California was not only the single  
          largest user of groundwater in the nation, extracting 14.5  
          million acre-feet annually, but that use represented 20% of all  
          the groundwater extracted in the entire United States.   
          Protecting the quality, quantity, and sustainability of  
          groundwater is critical.  Bulletin 118 estimated that 43% of all  
          Californians obtain their drinking water from groundwater.  Yet,  
          despite California's heavy reliance on groundwater, basic  
          information for many of the groundwater basins is lacking.  

          Bulletin 118 highlighted the need for water managers and local  
          land use planners to identify groundwater recharge areas and  
          protect them from paving and contamination in order to ensure  
          they could continue to replenish high quality groundwater.  

          Supporters of this bill feel it takes modest but important steps  
          and will "provide for increased coordination and consultation  
          between California's water supply agencies and land use approval  
          agencies and the protection of prime recharge areas in  
          California's groundwater basins."
