 Conduct Baseline Sensitivity Analysis 1.Use 10-year baseline with 2005 results 2.Use 10-year baseline with 2000 midpoint 3.Change the calculator to allow different midpoint years  Look at the geographic representation of the random sample  Consider using a scalar or multiplier rather than adding percentage for the adjustment factor

 Consider using sewer flows to verify or determine indoor residential  Document the methodology DWR will use to determine progress towards 20x 2020  Consider allowing an appeals process

 Ran the BMP calculator for 9 more sample agencies  Completed a baseline sensitivity analysis for 2005 midpoint  Ran additional example targets for DWR II  Have calculated BMP savings reductions using both the multiplier and percentage adjustment factor  Proposal on adjustment factor exemption to address undue hardship

Suppliers who meet the following conditions would be exempt from the statewide adjustment requirement: Based on the BMP calculator 1. Have zero savings requirement for the following BMPs 1.Water loss 2.Metering 3.Landscape Budgets 2. And have less than 1 GPCD savings requirement for SF and MF toilets and residential showerheads
