  8. Stakeholders comments on turf Warm season only Backyards, sports fields only Avoid invasive plants in shrubs beds Turf growers are hard hit by drought Need to recognize lower water varieties and functions Choose Turf areas more carefully, not just the default groundcover

  9. Stakeholders on irrigation efficiency: Limit application rate, know infiltration rate of soil Run times (drip) and multiple runtimes, Use Sensors and SMART controllers Master valves, Flow Sensors, Pressure Regulation Hydrometers, Lower ETAF (water allowance) More emphasis on soils

  10. Sustainability and the new purpose • MWELO goes beyond water conservation • Addressing other resource Acknowledging California’s climate • Energy, air, habitat, water quality • Drought survival, protect the investment of landscapes

  11. MWELO details • In effect Dec 1, 2015 • Lower water budget • CII ETAF 0.45 • Residential ETAF 0.55 • SLA remains at ETAF 1.0 • Applicability at 500 Sq. Ft.

  12. Reporting by Local Agencies • Local WELO details • Status of adoption • Number and types of applicable projects • Housing starts, commercial development, retrofits • Review procedures and Verification • Enforcement measures • Challenges • Education and other needs

  13. Value of Reporting by Local Agencies • Never quantified landscapes before on statewide basis • No idea of changing demand • Data for long term planning • Data for Urban Water Management Planning • Quantify Outdoor vs. Indoor water use • Changing Trends • Marketing information?

  14. Next steps • Independent Technical Panel – Proposing updates to the MWELO • Other proposals are tied to MWELO standards • Stakeholder committee 2016— • Examine long standing complicated issues • Existing landscapes • Find solutions by collaboration: government, industry, non-profits
