City Engineer Westby reviewed the staff report and explained the purpose of this case is to <br />consider recommending City Council approval of the September 2017 Comprehensive Sanitary <br />Sewer Study Update. It was noted the 2012 Comprehensive Sanitary Sewer Study was prepared <br />anitary Sewer Study Update <br />incorporates current population and land use projection, addresses impact <br />sewer infrastructure due to development that has occurred in the last five years as well as <br />currently proposed and projected development out to the year 2040 to be consistent with the <br />2040 Comprehensive Plan updates that are underway. City Engineer Westby referenced <br />documents attached to the staff report, noting the cost difference to include the utilities <br />infrastructure estimates and it will also address rate adjustments and a system to serve the entire <br />City. He presented development rates as detailed in the staff report as well as key <br />considerations. <br /> <br />Chairperson Riley noted that is a big change in project developments rates. <br /> <br />City Engineer Westby explained they considered the last four years of development and actual <br />connections during that time, determining the average is 196 since the 2012 Study was <br />completed. Also, high density was increased from 25% to 50%. He stated it is felt to be the <br />most accurate at this time going forward. <br /> <br />Chairperson Riley stated he is not in a position to say it is wrong but it feels low to him <br />considering all of the projects that are under discussion. <br /> <br />City Engineer Westby stated staff has been looking at areas left to be developed and a realistic <br />projection. He agreed a lot of developments are under discussion, but noted that is not <br />sustainable in the long term. <br /> <br />th <br />Councilmember Johns asked if the 167 node is the only separate area. <br /> <br />City Engineer Westby stated it is a high interest area and the City Council has discussed their <br />desire to rejuvenate that area for development. In addition, staff fields a lot of calls from <br />perspective developers about that area. City Engineer Westby completed presentation of the <br />staff report, reviewing key considerations to serve the entire City with a sewer system, which <br />th <br />brings in the issue of the 167 node. He explained staff is also requesting a recommendation on <br />th <br />whether sanitary sewer infrastructure needed to serve the 167 node, and areas to the north and <br />east, should be incorporated into the update, which will ensure that a properly designed and <br />th <br />coordinated sanitary sewer system will be available for future development of the 167 node and <br />areas to the north and east. <br /> <br />Chairperson Riley asked if it is a worthy goal to provide the ability for every property to connect. <br /> <br />City Engineer Westby stated that is the most fiscally responsible, noting septic system <br />requirements are becoming more restrictive over time and looking ahead, there will be more <br />pushback from the Department of Health and PCA to get people off well and septic. At this time, <br />however, the Charter does not allow the City to compel connection. He stated it still makes <br />Public Works Committee / November 21, 2017 <br />Page 8 of 16 <br /> <br />
