Ms. McPherson <br />October 24, 2002 <br />Page Two <br /> <br />· Assuming there is not capacity for this entire area, determination of the size of lift station and <br /> forcemain and routing necessary to convey sewage generated from this area to the <br /> wastewater treatment plant. <br />· An analysis of the needs for water production, treatment and storage necessary to serve the <br /> potential land uses of the area. Determination of whether or not it would be better to extend <br /> the existing water system northward into this area, or construct an independent, free-standing <br /> water system. <br />· An analysis of the wastewater treatment plant capacity now and through future expansions, <br /> relative to the potential for new sewer flow generation from this area. This would include a <br /> cursory review of the current urban service area relative to potential sewage flow under a fully <br /> developed condition versus the potential ultimate capacity at the wastewater treatment plant <br /> site. <br />· A preliminary estimate of the major components necessary to provide sanitary sewer and <br /> water service to this area. This would include gross assumptions on the necessary trunk <br /> system to service the area. The purpose of the cost estimating would be to determine whether <br /> or not the extension of City services appears to be financially feasible, and if so, how large an <br /> area needs to be provided these services to make it financially feasible. <br /> <br />I do not anticipate any fieldwork being necessary to complete a study of this nature. I believe the <br />necessary information is available in the Gravel Mining ElS, information from the latest wastewater <br />treatment plant expansion and our knowledge of the existing sewer collection system. Assuming the <br />answer to the question of whether or not this area can be provide sanitary sewer service from the <br />existing wastewater treatment plant is yes, I would estimate that it would take approximately 45 to 60 <br />days to complete this study and that the cost would be approximately $25,000. As with other studies <br />of this nature, I assume you will want Tiller Corporation to put up a portion of the cost for the study. I <br />would suggest they be asked to escrow $10,000 towards the total cost of the study. <br /> <br />If you have any questions regarding this issue or would like to discuss it further, please call. <br /> <br />Sincerely, <br /> <br />Howard R.
