3. Governor’s Three-Part Conservation Message A target: “20% reduction in per-capita use by 2020” A target: “20% reduction in per-capita use by 2020” An order: “state agencies to develop this more aggressive plan” An order: “state agencies to develop this more aggressive plan” An invitation: “legislation to incorporate this goal into statute” An invitation: “legislation to incorporate this goal into statute”

4. The Target: Is It Achievable? Current urban water use = 8.7 million acre-feet per year Current urban water use = 8.7 million acre-feet per year 20% reduction = 1.74 million acre-feet per year 20% reduction = 1.74 million acre-feet per year

8. Legislating a Conservation Target AB 2175 (Laird & Feuer) complements a state plan by encouraging local action. The bill would: Place 20% State Target in Law Place 20% State Target in Law Hold Water Suppliers to Specific Targets Hold Water Suppliers to Specific Targets Set Numerical Target for Ag Conservation Set Numerical Target for Ag Conservation Give DWR Power to Require Specific Actions Give DWR Power to Require Specific Actions Bill’s next hearing: Senate Appropriations

9. Climate Adjustments Bill sets “California Standard” per capita targets Bill sets “California Standard” per capita targets Targets vary by ET Zone Targets vary by ET Zone

10. Potential Amendments Don’t Hold Local Suppliers to State Target Don’t Hold Local Suppliers to State Target Keep DWR Out of Regulatory Role Keep DWR Out of Regulatory Role Increase Flexibility (Base Year, CII, Unique Situations) Increase Flexibility (Base Year, CII, Unique Situations) Establish an Ag Water Mgmt. Planning Act Establish an Ag Water Mgmt. Planning Act
