With aggregate data it's difficult to conclude whether water customers are 129 modifying their behavior or if the volume is decreasing for other reasons such as the loss of high-water 13o users (manufacturing, hotels, apartments, etc.) or higher summertime rainfall totals. 131 132 As we'll discuss further below, the average monthly summertime rainfall totals have increased somewhat 133 since 2009, however during this same period the City has seen growth in housing units, retail 134 establishments, and other commercial uses. The bottom line is that overall consumption has declined, 135 while the City has grown. 136 137 The neat graph depicts the average quarterly wintertime usage for single-family homes. 138 Page 6 of 10 2015 2016 Stormwater Base Rate Category Rate Rate Comments Single -Family Residential & Duplex $ 12.00 $ 12.35 Standard SF rate _Multi -Family & Churches 92.75 95.55 Standard SF rate x 7.75 Cemeteries & Golf Course 9.30 9.30 Standard SF rate x 0.75 Parks 27.90 28.75 Standard SF rate x 2.35 Schools & Community Centers 46.45 46.45 Standard SF rate x 3.75 Commercial & Industrial 183.65 191.00 Standard SF rate x 15.50 Rates for single-family are per housing unit; all others are per acre qW 2015 2016 i Recvclina Rate Cateaory Rate Rate Comments Single -Family $ 5.50 $ 5.60 Standard rate Multi -Family 5.50 5.60 Standard rate Water Usage History The series of graphs presented below depict water customer consumption patterns over the past 8 years beginning with a depiction of the citywide water consumption. 1,800,000 1,600,000 1,400,000 1,200,000 1,000,000 800,000 600,000 400,000 200,000 Citywide Water Usage (000's gals.) 2007 2008 2009 2010 2011 2012 2013 2014 ■ Billed Consumption 126 127 As indicated in the graph, citywide consumption has generally been falling over the past 8 years — a 21% 128 reduction since 2007.
