Feasibility Study 2010 Street Overlay Improvements City of Elk River, MN III. PROPOSED IMPROVEMENTS The proposed improvements in Project Locations 1, 2 and 4 is to provide a l~/z-inch bituminous overlay on the existing bituminous streets. In these areas the existing pavement structure appears stable and not subject to major deficiencies, so a 1'/z-inch overlay will be adequate to provide additional strength and surface improvements. The City Street Department will patch any severely damaged pavement areas before the overlay project will begin. In addition to the overlay, bituminous milling may be performed in front of relatively flat driveways to ensure they can be made to match properly with the newly overlaid street. The improvements to in these Project Locations are shown in more detail on Figures 2, 3 and 5. The streets reviewed in Project Locations I, 2, and 4 are in need of repair. The project is necessary to provide the property owners of the project areas with a safe and adequate public transportation system. If the overlay improvements describe above are not completed in a timely faslvon, the roads will continue to deteriorate and reach a point where an overlay will not be a feasible alternative. This project will minimize future maintenance costs and increase traffic safety. The proposed improvements proposed in Project Location 3 are shown on Figure No. 4. The west and south sides of the Industrial Boulevard NW loop road will receive a 2-inch overlay. Prior to the overlay, the bituminous will be milled along the existing gutter in order to match the new overlay to the existing gutter. The east side of the lndustrial Boulevard loop, I92°`~ Court and Triangle Road NW will be "reclaimed" and overlaid with 4 inches of bituminous pavement. Reclaiming of bituminous pavement is a process whereby the pavement and underlying aggregate base are milled together in-place, re-graded and re-compacted as base material for the new pavement overlay. Concrete curb and gutter will be constructed where it currently does not exist on Industrial Boulevard NW and 192°`~ Court. Curb and gutter will also be added on the northwest end of Triangle Road, along with catch basins, storm sewer lateral and outlet. The streets in Project Location 3 are in need of improvement. The project is necessary to provide adequate streets to serve the property owners in the Industrial Park. If the improvements describe above are not done in a timely fashion, the roads will continue to deteriorate and reach a point where the proposed improvements will not be a feasible alternative. IV. EASEMENT AND PERMITS All improvements are proposed to be completed within the existing right-of-way. No permits from any local or state agencies will be required for this project. ©Bnlton & Monk, bic. 2010. All Ki~lltc Raceri~ed Page 3 816.102234 June 3, 2010
