Pequot Lakes -Hwy 371 North March 23, 2005 Page 9 of 10 29. There is a City watermain in a casing pipe under TH 371 on the south side of Pillsbury Street, and the casing pipe will need to be extended at the City's cost as part of this project. This watermain(uncased) then turns north and parallels about 15 feet within the easterly TH 371 R/W for about 260 feet north before turning east along the south R/W of Morehouse Drive. 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. The degree to which the existing casing pipe will need to be extended and whether or not the existing watermain paralleling the highway will need to be cased will need to be determined during the design phase when MnDOT sets the highway's profile and corresponding cross sections. At this stage, for the purposes of estimating a possible cost to the City(but not knowing the exact highway layout),we used 75 feet of additional casing pipe installed perpendicular to the highway and 260 feet of casing pipe installed parallel to the highway(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$50,250 in construction cost. 30. At the full access Morehouse Drive intersection,MnDOT has projected traffic volumes and the results do not come close to warranting a traffic signal at this intersection. (MnDOT has warrants, a term for a list of criteria,that have to be met for the installation of a traffic signal as well as access management guidelines-the spacing varies from 0.25 miles to 1 mile depending on whether it is urban to rural.) The Committee asked and MnDOT did review with their traffic modeling people that buses from the school as well as the "industrial" land uses around/to the Morehouse Drive intersection were taken into account when analyzing for a traffic signal warrant. The City should note that if there were a traffic signal located here,the cost is split by who has jurisdiction on each leg.Thus,in this case,MnDOT would be 50%and the City would be 50%.

On the west side,the property is zoned Industrial.MnDOT will review possible larger radii at intersections along the service road in this area during final design. 32. On the west side,the service road`meanders' slightly to the east to abut the back lot line of the C:\Documents and SettingsWdministrator\L.ocal Settings\Temporary Internet Files\OLKB\032305 Council Workshop update-memo.doc
