10. We Finished It! 43 recommendations 76 specific actions to implement the recommendations Top 12 AB 1881 submitted

11. New Technology Programs Et Weather Data For Irrigation Scheduling

12. The Study Area

13. Study Objectives Characterize Runoff Quantity and Water Quality –Dry Weather –Storm Conditions Evaluate Methods of Reducing Runoff

14. Study Design Control Neighborhood #1 Control Neighborhood #2 Control Neighborhood #3 Education Neighborhood Retrofit and Education Neighborhood Flows to San Diego Creek and Newport Bay = Water quality and flow monitoring locations

15. Study Findings 41.2 gpd saved annual average with ET controllers and education 25.6 gpd saved with education 64-71% runoff flow reduction in combined area 79% runoff reduction in one specific neighborhood

16. Study Implications Landscape water not just a drought issue or even a peaking issue Multiple environmental benefits of regional and statewide significance An important partner in basin management: Runoff reduction, pollutant reduction, reduced wastewater treatment, reduced green waste management

17. Green Building Issues LEED (USGBC) only awards 6 points for water efficiency LEED Water Efficiency Technical Advisory Group working to make significant improvements (Council participation) Other green building initiatives similarly weak on water efficiency “California Friendly” and “Smart from the Start” pilot programs in California
