November 3,2014 WIDSETH Proposal for Old 371 —Main to Rae City of Pequot Lakes SMITH Page 3 NOLTING From the south leq of Gravdahl Drive to the south leq of Rae Avenue (about 1,200 feet) a. Curb and guttered street. b. Two traffic lanes, each 12 feet wide. c. No parallel parking lanes. There will be 2 feet wide concrete gutters from edge of travel lane to face of curb. d. The total width of the street will be 28 feet face-of-curb to face-of-curb. e. For reference, at the south side of the intersection with the south leg of Rae Avenue, Old 371 is a 36 feet wide face-of-curb to face-of-curb section (from the 1990's Industrial/ Business Park improvements). f. There will not be any widening at or additional turn lanes for intersections. g. No sidewalks. There are none now, and the Paul Bunyan Trail is immediately to the west of the "Rae residential subdivision". h. With a 66 feet wide R/W and a 28 feet wide street, there would be a little over 18 feet of grass from behind the curb out to the R/W. i. No decorative street lights. j. Trees behind the curb (each one will not survive; it will take a while before they become mature). k. With the C&G, curb inlets/catch basins and storm sewer pipe will be needed. I. The initial plan is to pipe the drainage up to the existing infiltration basin on the north and east side of the intersection with the south leg of Gravdahl Drive. However,the elevations may not permit this—i.e. there may need to be a new infiltration basin constructed near an intermediate low point. This would involve easement definition and acquisition. m. The volume of the existing Gravdahl infiltration basin will need to be reviewed. Overflow of this infiltration basin in big storms should be looked at; possibly creating an overflow grassed swale to the south past the City lift station and then to the east towards a natural low area. This would involve easement definition and acquisition. n. From Crow Wing County's GIS website, it looks like there is only 33 feet of"recorded" R/W on the west side. The City would need to formally obtain/properly record 66 feet of R/W. o. There is watermain under the roadway down to the north leg of Rae Avenue, about"mid- block"for a fire hydrant, and at the south leg of Rae Avenue. There are no known problems, so it should not have to be replaced. However, the bury depth will be reviewed via valve depths. If a curb and guttered street lessens the cover over the watermain, insulation may need to be incorporated. Or, worse case, the watermain will need to be lowered. p. This may be the opportunity, though, for the City to install a few more valves in the watermain (usually at intersections). q. Except for an east-west crossing at Gravdahl Drive and improvements in the south Rae Avenue intersection (similar comments on cover to those made in regards to watermain), there is no sanitary sewer under the roadway. For the above improvements, following is our corresponding scope of services. 1. Research property corners, and locate horizontal and vertical survey control. 2. Make a Gopher State One Call and preferably obtain field information from utilities, but if not provided, obtain design maps from them. 3. Field survey all underground and above ground features along the Old 371 corridor to prepare a base map.
