A project location map is provided as Exhibit 1 in Appendix A. 2. PROPOSED PUBLIC IMPROVEMENTS The following is a summary of the proposed street, storm sewer, sanitary sewer, water main, and private utility improvements included as a part of this project. Exhibits 2 and 3 in Appendix A illustrate the proposed improvements. A. Street Improvements Rice Street This project includes the reconstruction of Rice Street from approximately 700 feet south of County Road B West to 500 feet north of County Road B2 West. The total length of proposed street reconstruction is approximately 3,900 feet. Rice Street is currently a 48-foot wide three-lane urban section roadway with bituminous pavement and concrete curb and gutter. There are numerous turn lanes throughout the corridor that widen the existing roadway to a maximum width of 71 feet. The proposed improvements include the reconstruction of Rice Street to a four-lane divided urban section with dedicated turn lanes at all major intersections. The proposed raised concrete median will consist of stamped integrally colored concrete with cut outs for planters with street trees where sufficient median width exists. The proposed pavement section includes 7-inches of bituminous pavement and 5-inches of aggregate base. Improvements are proposed at all four major intersections within the project limits: County Road B West, the TH 36 ramps, Minnesota Avenue, and County Road B2 West. Intersection improvements are proposed to include new traffic signal systems and dedicated turn lanes. Concrete sidewalk exists along the west side of Rice Street throughout the project area. As a part of the proposed improvements, new six-foot wide concrete sidewalk with a two-foot integrally colored and stamped concrete maintenance edge is proposed along both sides of Rice Street. Retaining walls are proposed at numerous locations along Rice Street to protect existing property features from being disturbed. Three types of retaining walls are to be used throughout the project. A sheet pile wall will be constructed on Rice Street in front of Super America. The proximity of Super America's gas storage tanks to the proposed right-of--way does not allow a modular block wall to be constructed in this location without disturbing the storage tanks. The sheet pile wall will be approximately four feet tall. A wet-cast modular block wall will be constructed in front of the Northeast Metro Intermediate School. The wall in front of the school will be four to eight feet tall. Dry- cast modular block retaining walls will be constructed in front of McDonald's, Arby's, 2
