resolved, and could be a contingency of the approval. He expressed concern about private septic systems, particularly where there is not an anticipated connection to the MUSA any time in the near future. Commissioner Brauer asked if it would be possible to go ahead with rezoning this to the PUD, as no one seems to be opposed to the concept of the plan for this site. He indicated it does need to be determined where the septic system will be located. Chairperson Nixt indicated they will not be able to determine tonight whether the septic system can be located on this site. The developer has done soil borings to maximize the location of the drainfield, and they don't appear to have been close enough to where the actual drainfield will be sited. Due to this the soil expert has indicated he does not know what borings will apply to the drainfield. Mr. Walz stated the soil tester bored the areas where the drainfield will likely be located. The results of those two borings indicated it was the best location out of the eight pits that were completed. There is no way without digging the pit to determine 100% viability, and that is where the problem lies. City Engineer Jankowski explained the area was suspect because it was known that there was filling in the area. This test confirmed there have been areas filled, but they found a couple of boring areas where there was no fill. His interpretation of the report is that more testing is needed to ensure that the whole area has not been filled. Chairperson Nixt asked what is needed at this level to recommend whether to proceed with a recommendation on the preliminary plat and site plan. City Engineer Jankowski advised the Planning Commission could pass the preliminary plat and site plan with a contingency regarding the septic system. Once the preliminary plat has been approved there are substantial rights that would be applied to the applicant. Commissioner Van Scoy asked what type of contingencies would be recommended. City Engineer Jankowski advised there could be a contingency on adequate soils being available for an on-site system and a replacement system. Associate Planner Dalnes suggested the four items listed in Staff's case as reasons for tabling preliminary plat and site plan could be included as contingencies for approval. Commissioner Van Scoy inquired about the testing being disruptive to the septic system. Chairperson Nixt indicated under code it is required to have a main site and an alternate site for the septic system. If a traditional perking system cannot be utilized there are other options that would increase the cost. The development will not be given the go ahead until the City is convinced the on-site system that will serve this area will be acceptable for the proposed use with an alternate. -276-
