308 established a standard consumption for their home no matter the rate, based on the 309 rate fluctuations over that same period. Even when the water rates were lowered 310 by 20% in 2008-2009, Mr. Miller reported that the City had actually seen the 311 reverse happen with more consumption when rates increased. Mr. Miller 312 questioned if that indicated there was not enough incentive offered to conserve 313 water or homeowners were simply not willing to move beyond their established 314 household standards of consumption. 315 316 Reviewing summertime consumption during that same period, and also factoring 317 in annual rainfall, Mr. Miller noted that aggregate behavior did change when there 318 was more rainfall. While it didn't matter for some homeowners in the amount they 319 ran their sprinkler or irrigation system compared to the amount of rainfall received, 320 Mr. Miller noted in the aggregate it did fluctuate indicating some were making a 321 conscious decision to adjust their sprinkling habits accordingly. However, while 322 indicating more fluctuation in ranges, Mr. Miller questioned if it was statistically 323 significant even though to him it seemed to indicate consumers were adjusting their 324 behavior and consumption accordingly. However, Mr. Miller questioned again if 325 this was due to not enough incentive to consery lack of interest in changing 326 established behavior for sumpt. n habit 327 °1 328 Specific to water conservation, Mr. Miller no e `higher tiers could be created for 329 those deemed higher consumption customers, but noted there were few people 330 fitting into that higher water category. Historically, Mr. Miller reported that most 331 single-family homes in Roseville used 15,000 to 16,000 gallons of water per quarter 332 or less than that. Based on that historical data, Mr. Miller noted that compared to 333 other inner -ring suburb homes, Roseville's consumption was very low; and further 334 noted that the majority of Roseville homes didn't have a built in lawn sprinkler 335 system. While unsure how to make a determination, based on his analysis, Mr. 336 Miller questioned if water rates were even doubled whether it would incent people 337 to use less water. 338 339 Mr. Miller suggestedthe t effective step may be to increase education and 340 outreach by providing information to residents on benefits of low volume water 341 devises, and awareness of how little water it actually takes for an established lawn 342 to proactivel incent water conservation. 343 344 Chair Stenlun sted the number of snowbirds from one winter to the next may 345 skew data; but . Miller responded that may be, but historically from one year to 346 the next, his analysis had shown little change in the number of snowbirds each year. 347 348 Member Seigler noted with a tiered rate structure it may actually erroneously 349 punish households with a lot of kids or even a few kids. 350 351 Mr. Miller reported that this had been found out in trying the tier system several 352 years ago and difficulty in defining tiers to reward those making an effort to 353 conserve without penalizing larger families.
