4. PROPOSED IMPROVEMENTS <br />4.1 Roadway <br />The proposed roadway improvements for the North Sunset Lake Area Street Improvement <br />Project include the reclamation of the existing asphalt pavement and aggregate base and minor <br />subgrade corrections only as needed. <br />A typical roadway section is included on Figure 2 in Appendix A. The pavement section will be <br />verified during final design once soil testing information is available. <br />4.2 Drainage Improvements <br />The existing drainage systems will be maintained and culverts replaced as needed with only <br />minor drainage improvements to accommodate the proposed roadway alignment. Existing <br />vertical and horizontal alignments will be maintained to the greatest extent possible. <br />4.3 Right-of-Way/Easements <br />The proposed improvements will be completed within the existing right-of-way and no <br />acquisitions are proposed. <br />4.4 Permits/Approvals <br />The anticipated permits and approvals required and the respective regulatory agencies are listed <br />below: <br />■ City of Hugo.............................................................. RCWD Permit/Wetlands <br />■ MN Pollution Control Agency NPDES.............................Erosion/Stormwater <br />4.5 Construction Access/Staging <br />The contractor will be responsible for providing access to all properties throughout the project. <br />The proposed methods of pavement rehabilitation will typically allow residents to drive on the <br />roadway surface during construction. Adequately signed detours will be identified to direct <br />traffic around the construction zones and notify users of the increased truck and construction <br />activity. Detours will be used only if absolutely necessary to ensure the safety of residents and <br />construction workers alike. <br />Feasibility Report <br />North Sunset Lake Area Street Improvement Project <br />City of Hugo, MN <br />WSB Project No. 1904-930 Page 4 <br />
