The <br /> roadway is currently in need of repairs/reconstruction and the issue was brought about by <br /> ST~(;Cj[':~At the County through the possibility of County Road F being "turned back" to the City of <br /> . <br /> Arden Hills. <br /> SL'~'iE;fING <br /> Using traffic volumes obtained from Ramsey County, the proposed design was <br /> Ti;l,;[;C determined. The volumes are 3700 vehicles per day at Interstate 35W and 4200 vehicles <br /> per day at Old Snelling Road. Using Minnesota State Aid design standards, the projected <br /> TR.t.J'J$?GRTATiON traffic volumes at twenty years are approximately 6,200 vehicles per day. The costs <br /> outlined in this letter include the reconstruction of County Road F to a 36-foot wide, nine- <br /> ton urban roadway with concrete curb and gutter. The street would provide two driving <br /> lanes and a single parking lane and the costs associated with the construction are <br /> enclosed. These costs reflect approximately five inches of bituminous, eight inches of <br /> aggregate base and an eighteen-inch subcut which has been typical in Arden Hills. The <br /> existing right-of-way for the roadway is 66-feet in width at most locations and 40 feet off <br /> of the centerline of the roadway along several sections of the roadway. Additional right- <br /> of-way should not be required if the roadway is constructed as proposed. <br /> 1326 Energy Pork orne The estimated cost of constructing the nine-ton roadway is approximately $606,000. An <br /> additional'32 % should be added to the construction costs for overhead (which includes <br /> 51. Paul, MN 55108 engineering, fiscal, legal and administrative costs). This would result in a street <br /> 6IH44.4389 reconstruction project cost of approximately $788,000. In addition to the roadway <br /> fox: 612-644.9446 reconstruction, storm drainage improvements would be constructed.
