Proposed Improvements <br />4.1 Surface <br />Improvements proposed are intended to improve the design strength of the pavement system and provide <br />a street surface with an extended life. Improvements along 125th Street North from Goodview Avenue <br />North to 122nd Street North consist of a bituminous pavement reclamation matching the existing <br />pavement width. Reclamation is the process by which the existing deteriorating roadway surface is <br />reused as aggregate roadway base for the new street section. <br /> <br />Reconstruction of Upper Heather Avenue and Heather Avenue is intended to improve the design strength <br />of the pavement system and provide a street surface with an extended life for the City of Wyoming. <br />Reconstruction of the roadways will include removal of the existing asphalt surface, removal and <br />replacement of the existing aggregate section, new asphalt pavement, and installation of concrete curb <br />and gutter. In addition, the roadway will be narrowed from the existing 32-foot-wide roadway to a 28-foot- <br />wide roadway (as measured from face of curb to face of curb). <br /> <br />Street grades are proposed to very closely match the existing grades to minimize construction impacts to <br />adjacent properties. Minor adjustments to some of the existing roadway vertical profiles will be proposed <br />to improve pavement drainage conditions where feasible. <br /> <br />Roads cores will be taken as a part of final design to determine the existing class 5 and pavement <br />thickness. This will determine the necessary reclamation depth and if there is need for additional <br />subgrade preparation. <br /> <br />The typical sections for both existing and proposed street improvements are included in Appendix A. <br /> <br />4.2 Storm Sewer <br />The proposed project will maintain the existing drainage patterns and discharge points to the greatest <br />extent possible. Deficient culverts will be replaced with reinforced concrete pipe (RCP) as necessary to <br />convey storm water runoff. <br /> <br />The existing storm sewer system along Upper Heather Avenue and Heather Avenue will be improved by <br />the addition of catch basins along the roadway to better accommodate area drainage and the extension <br />of new storm sewer where facilities do not currently exist. <br />4.3 Watermain <br />Water main improvements are not proposed to be included with this improvement project. <br /> <br />4.4 Sanitary Sewer <br />Sanitary sewer improvements are not proposed to be included with this improvement project. <br /> <br />4.5 Permits/Approvals <br />The anticipated permits and approvals required, and the respective regulatory agencies are listed below. <br /> <br /> City of Hugo ......................................................................Drainage/Erosion Control Permit
