Context for a Conservation Target




Second Year of Dry Conditions
Increasing Environmental Constraints on Delta
Pumping
Delta Vulnerable to Floods, Earthquakes,
Rodents
Climate Change
Governor’s Three-Part
Conservation Message



A target: “20% reduction in per-capita use by
2020”
An order: “state agencies to develop this more
aggressive plan”
An invitation: “legislation to incorporate this
goal into statute”
The Target: Is It Achievable?

Current urban water use = 8.7 million acre-feet
per year

20% reduction = 1.74 million acre-feet per year

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
 Hold Water Suppliers to Specific Targets
 Set Numerical Target for Ag Conservation
 Give DWR Power to Require Specific Actions
Bill’s next hearing: Senate Appropriations
Climate
Adjustments


Bill sets
“California
Standard” per
capita targets
Targets vary by
ET Zone
Potential Amendments




Don’t Hold Local Suppliers to State Target
Keep DWR Out of Regulatory Role
Increase Flexibility (Base Year, CII, Unique
Situations)
Establish an Ag Water Mgmt.
