. Ramsey County officials indicate that they expect a CIR pavement surface to last 15 to 20 years before major maintenance or reconstruetion would be required. By comparison, the County estimates a road with a standard overlay to have a shorter "life" on the order of 5 to 12 years, depending on the amount of heavy truck traffic. It is clear that this roadway has significantly high volumes of truck traffie, which would result in expected "lives" toward the lower range of years. Customarily, cold in-place recycling projects do not include work to correct sub grade soils. This work would add a fifth step to the eIR project by requiring the pulverized surface to be removed while the subgrade excavation is completed. For Dunlap Street, the subcutting of the existing soils and placement of drain tile would significantly increase the project cost. The third option would provide the City a roadway with the longest "life", short of reconstruction, at a significantly lower cost than reconstruction. These two costs will be compared in the Cost . section of this study. EASEMENTS AND PERMITS Dunlap Street has a 60 foot right-of-way from Red Fox Road to Grey Fox Road. It does not appear that any additional easements will be required to complete a cold in-place recycling or reconstruction project, as construction would be limited to the road surface area or roadside boulevard area. - ESTIMATED COSTS The estimated construction and project costs for Options 1 and 3 to improve Dunlap Street are provided in the following tables. Option 2 has been discounted as not being feasible and therefore, no costs have been estimated for it. . 7
