<br />Chairperson Nixt indicated the overall site plan will not change substantially as a result of the <br />findings that may be obtained from additional soils testing. <br /> <br />Mr. Walz stated they have been given the requirement to do additional testing to dig one 8-foot <br />test pit for every 10,000 square feet of septic system. The proposed septic system is only 2,400 <br />square feet; the total square footage would be less than 10,000 square feet, so essentially they <br />only need do to one test. He stated they have done eight test pits throughout the two different <br />properties to determine the best site for the septic system. <br /> <br />Chairperson Nixt asked if the testing was done through a qualified and certified subcontractor <br />who was approved to make the soil assessments. <br /> <br />Mr. Walz replied he had received notification on Wednesday evening that they needed a report <br />submitted within 72 hours. He contacted a licensed soil scientist. This individual, the septic <br />designer and himself conducted the test as a team with a backhoe. <br /> <br />Commissioner VanScoy asked if the report meets the requirements of the Engineering <br />Department to make a determination regarding the septic system. <br /> <br />City Engineer Jankowski explained the report includes the results of the soil test; there are no <br />septic designs attached to the report. <br /> <br />Associate Planner DaInes indicated the report states that the results are inconclusive and that <br />more testing needs to be done for verification. The report does not stand by the assertion that this <br />soil will 100% support a septic system; the report calls for more testing. <br /> <br />Chairperson Nixt noted if the soil is not acceptable for a conventional system there are other <br />types of system designs, but they would drive the cost up considerably. <br /> <br />Mr. Vick Hagenah, Septic System Designer, described the location and results of soil borings and <br />test pits He thinks the soil is very sound in this location. He walked the whole area and didn't <br />see anything really disruptive. <br /> <br />Chairperson Nixt requested an estimate of the size of drain field that would be needed. <br /> <br />Associate Planner DaInes indicated she has talked to Steve Lutmer and Mike McDowell about <br />the drain field. Mr. Lutmer uses the U ofM estimated flow rate chart. The sizing estimated by <br />Mr. Hagenah is pretty close to what Mr. Lutmer indicated, with the possibility of more <br />employees being added to the estimated number of employees. 2,200 square feet would be a <br />good estimate for the size of the drain field. <br /> <br />Chairperson Nixt asked how many square feet are available to locate the 2,200 square foot <br />estimated drain field and Associate Planner DaInes replied approximately one acre. <br /> <br />Chairperson Nixt indicated he would not hold the approval up with 50,000 square feet of <br />available space to site a 2,200 square foot drain field. This issue clearly needs to be resolved, <br /> <br />Planning Commission/October 5, 2006 <br />Page 12 of 20 <br />
