<br /> addition, a combination of storm sewer and drain tile would need to be extended to capture <br /> . subsurface water. The replacement material and storm sewer work together to provide a stronger <br /> base. Subcutting of the existing soils without storm sewer placement, however, would provide <br /> very little benefit for the roadway. <br /> PROPOSED IMPROVEMENTS <br /> As discussed, we have met on several occasions with Public Works Superintendent Dan Winkel to <br /> review the area and determine options available to improve Dunlap Street. The roadway is clearly <br /> in a failed eondition such that a simply overlay of the present roadway is not feasible. The three <br /> options available to the City to improve the roadway are: <br /> 1. Reconstruct entire roadway <br /> 2. Cut and patch distressed areas of the roadway then overlay the entire surface. <br /> 3. Recycle existing bituminous pavement and overlay the entire surface. <br /> . The condition of the existing roadway, as evidenced by the alligator cracking, raveling, rutting and <br /> potholes described earlier, indicates that the best option for this roadway would be reconstruction. <br /> Reconstruction is also recommended by the pavement management program used by City staff to <br /> determine reconstruction, overlay and seal coat projects. The field ratings for the City streets <br /> 'c., were last updated three years ago, so Dunlap Street has certainly not improved in the hierarehy of <br /> streets requiring work. A reconstruction project would include storm sewer improvements to <br /> - <br /> properly drain storm water runoff both above and below the surface of the roadway and <br /> construction of bituminous street improvements to serve the commercial/industrial area. Concrete <br /> curb and gutter would also be constructed. The street improvements would provide a 36 foot wide <br /> roadway and require a 2 to 3 foot subcut and replacement of the poor sub grade material. The <br /> reconstruction of Dunlap Street would be the most expensive of the three options, as will be <br /> discussed in the Cost section of this study, but would provide the longest term solution. <br /> . <br /> 4 <br />
