  4. Effects of Growth Water Resources and Population Growth, 2000-2020 Source: DOE/NETL (M. Chan, July 2002)

  5. 600,000 people and over 200,000 homes per year

  6. Residential Water Usage Source: AWWRF Residential End Uses of Water, 1999

  7. AB 2717 • Became law September, 2004 • CUWCC formed Landscape Task Force to review landscape water issues, make recommendations for improvements • Representatives from water suppliers, landscape & building industries, cities & counties, environmental groups, and state & federal agencies

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

  9. New Technology Programs Et Weather Data For Irrigation Scheduling

  10. The Study Area

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

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

  13. 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

  14. 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

  15. 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

  16. California Friendly “ Active Family”
