HomeMy WebLinkAbout8-7-2017 TRS TRACFONE SCHEDULES EMAILHi Jan and Nate, We have been looking harder at the population proportion calculations for Renton, and something has come up with how they were calculated. It turns out that the population sizes for various years for Renton that are found between census years online are not very correct at all. These online population figures show a very smooth, slight upward climb and then a bounce in 2010. But it turns out that the significant population bump for Renton occurred in 2008, when two large annexations were added. According to our records, the Benson Hill annexation added 16,272 residents, and the Aqua Barn annexation added another 2,200 new residents that same year. This means that the bump finally showing up during the census occurred two years earlier, but was not included in the more informal population counts used previous to the census. Because the population counts between censuses have proven so faulty, if it is alright with you, we would prefer to use only census years in our calculations. We have redone the schedules using the 2010 census's population proportion for 2008 onward, and the 2000 census population proportion for 2007. We believe that this would be a much more accurate approach to the estimation. But before we send this on to TracFone, we would like you to check to see if any of the other annexations were large population-wise. The 2010 jump online is more like 30,000, of which the Benson Hill/Aqua Barn annexations account for about 2/3, and the remainder may be due to regular population growth and small annexations, but it also may be due to a large one or two we are not aware of. We know that there have been a lot of annexations over the course of the audit (2007 to 2013), but we want to include the really big ones in our choice of methodology. So if there is any light you could shed on this situation, we would appreciate the additional information. We have attached the adjusted schedules so that you can see the effect of the new procedure. Thanks Jan and Nate. Hope you have been enjoying the sunshine. Tamara This email and any files attached to it are the property of Tax Recovery Services, LLC.
