Pequot Lakes-Hwy 371 North October 8, 2004 Page 11 of 13 For the purposes of estimating a cost to the City, I will assume 150 feet of casing pipe will need to be installed (excavation of existing sanitary sewer, installation of a `split' casing pipe, `welding' of the `split' casing pipe, and backfilling) at $150 per foot for a total of$22,500. 34. The City is aware that it has it has watermain in a casing pipe under TH 371 at Sibley Street (the UBC corner)that will need to be extended at the City's cost as a part of this project. This watermain was installed in 1999. Due to the unknown extent and timing of the proposed TH 371 improvements at that time, the City only paid for enough casing pipe to `cover' the existing highway. For the purposes of estimating a cost to the City, and not knowing the exact highway layout at this time, I will use 75 feet of additional casing pipe (excavation of existing watermain, installation of a `split' casing pipe, `welding' of the `split' casing pipe, and backfilling) at $150 per foot for a total of$11,250. 35. The City is aware that it has a sanitary sewer lift station in the southeast corner of the intersection of TH 371 and Sibley Street. There have been some questions as to the exact location of the TH 371's R/W line in this area(if the lift station would happen to be on R/W,the City would have to relocate it at their cost—this could be in the $150,000 to $200,000 range). The City's 1999 Water System Improvement construction drawings show the lift station being off of the TH 371 R/W. However, the lift station is close and as mentioned,there have been some questions raised as to the exact location of the R/W line. The City would like to work with MnDOT's surveyors to determine in the field the exact location of their R/W, especially in this area. 36. The City is aware it has a gravity sanitary sewer about 25 feet (this is an estimated dimension)within and paralleling the east R/W line of TH 371. This gravity sanitary sewer within the R/W comes down from Front Street for about 600 feet to Sibley Street next to the UBC. We understand that MnDOT does not require non-pressure lines within their R/W to be inside casing pipes.However,we also understand that this line is in the R/W by`permit' and if MnDOT needs it relocated(not sure what feasible relocation route there is)or cased due to its highway improvements, the City will have to bear this cost. There are no known problems with the condition of this sanitary sewer. However,the CAMy DocumentsWity ClerMIGHWAY 37 hComments to MnDOT-100804-memo.doc
