MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, February 10, 2020 6:00 o’clock p.m. _____________________________________________________________________________________ Page 5 of 15 Mr. Mueller asked what happens if it is in the middle of winter and it is frozen from driving over it. He does not think the line is ten feet down. The City should be able to show the as-built for him. Crosby asked Staff how far down the line is, and Barnhart stated they have an as-built but he could not find it. The building code has certain standards for how deep a sanitary sewer line should be buried. If it is less than that, it can be insulated. He said they could provide advice to the applicant and the commenter on what that depth is. Walsh said that would be good information to know and anybody with a locater should be able to do it. Johnson and Barnhart discussed the City’s certainty of the location of the sewer line based on the drawing associated with the project, and that the survey does not indicate the location as it only shows easements. Mr. Mueller, with Staff’s help, described the sewer line and concrete culvert/sewer connection locations on the map. Oakden used an aerial map to show the approximate location of the plumbing line, which Mr. Mueller agreed with, which is connected to the Mueller house. Both houses on the map go out the back and connect into it, going uphill, and Mr. Mueller noted the Staff’s pointer was in the location where the sewer line goes over and connects to it. Council members and Staff talked about how many times the road would cross over the Muellers' sewer line and the main sewer line and that it would cross the Muellers’ sewer line three times. Mr. Mueller said that is a main trunk in the road. Johnson asked Mr. Mueller if he was fine with the main trunk and it was not a concern. Walsh said the Muellers are worried about their connection on their property. Mr. Mueller said he is worried about his pipe which is going to get driven over. Johnson said he would be worried, too. Mr. Mueller referenced the manhole and said when everything was put in there, a concrete culvert was put in to access the back lot and there was a driveway there. Ms. Mueller said there was also a smaller house. Oakden referenced the drawings to show the as-built, the Muellers' service line, the manhole, and the second manhole on the back lot. Council members and Staff discussed the typical depth of sewer lines being ten feet and referred to elevations of 9.52 and 9.40 done in 1992 and that the sewer line looked to be at least ten feet down. Seals asked what if it was not, because she lives in that area and nothing is as they were told, either. Crosby noted people drive over sewer lines all the time and his road is over the sewer line.
