Patt of the request was to increase the drainfield size on four of the proposed lots. <br />Also information was requested for the lots that will require a pump and pump station to deliver the <br />effluent to the septic system. Please replace the old information with the revised sheet 6 and design <br />computation sheets. <br />The City also had some concerns with the disturbed soils on lot 4 . It appears that the top 2" or so of the <br />original soils in a po1tion of the septic system area was bladed or removed. Disturbed soils can impact <br />the operation of a septic system. When the percolation tests and soil borings were completed there was <br />some snow cover, so it was hard to determine if the disturbance was there prior to the testing. It seems <br />likely that it was disturbed prior to the snow. Also on this lot there was a set of tire tracks in the area <br />that was bladed or previously disturbed. Because the system is a below ground trench system it is <br />likely that it will not affect the performance of the system. The city may require additional testing in <br />this area when weather conditions will permit. It is very critical that the septic sites stay as natural and <br />undisturbed as possible. <br />If you have any questions in regards to this design, I will be happy to answer them.
