the south parcel, except in those areas near the pump house. However, re-establishing <br />disturbed areas is required; seed is acceptable. Ms. Dalnes explained the plan has been <br />revised to indicate a separate loading area for deliveries and commercial vehicles. No <br />changes were made to the width of the drive aisle in this area. <br />Associate Planner Dalnes. indicated a soils report has been submitted that calls for <br />additional study of soils in the exact drain field area. After analyzing the report it is still <br />unclear whether the site is viable for a septic system. The City Engineer will provide <br />further information regarding the soils report. Staff recommends tabling action until it <br />can be verified that the subsurface conditions are viable for a septic system, what the size <br />of the system will be, and where it would be located. <br />Citizen Input <br />Mr. Mike Walz, General Contractor representing Northfork Office Condos, stated he is <br />frustrated about how this situation is going. He just found out 15 minutes ago about the <br />recommendation to table this and require additional testing. According to his <br />conversation with Ms. Dalnes, the bottom line is that they need to excavate the entire site <br />to determine the viability of the septic system, which he finds completely ridiculous. In <br />doing excavation it will invalidate those locations anyways. His hope is that they will be <br />able to recommend moving forward with this pending final approval of the septic design. <br />City Engineer Jankowski explained the soils report indicates that four pits were <br />completed; buried debris was found in two of the pits where fill had been placed. Two of <br />the pits did not have any material. Mr. Jankowski advised the report suggests that it is <br />possible that the two areas where there was no fill found may be an acceptable area for <br />the septic. The indication is that there needs to be additional testing to determine the <br />extent of the fill and to make sure these areas are acceptable to accommodate the septic <br />system. This report states the boring done is only a partial fulfillment of the subsurface <br />assessment requested by the City. <br />Chairperson Nixt requested clarification that this septic system will be for a commercial <br />development and would meet commercial sizing. The size of the drain field for the <br />conventional system would be based on the type of use and the native soils the drain field <br />would be established in. The test is inconclusive as to the soils; therefore they are not <br />able to properly size the drain field. <br />City Engineer Jankowski explained at this point it is not known how big the drain field <br />needs to be because the infiltration rates are not known. There is cautionary note in the <br />soils report about infiltration rates; the report states: If the very top soil layer observed <br />and tested for extends below the drain field the rate of infiltration .could be much lower <br />than the rate estimated. Mr. Jankowski advised there is some uncertainty expressed in <br />the report, and an infiltration test is recommended. They can then size how much area is <br />needed, and then do borings to determine if there is sufficient area. <br />-274- <br />
