V. PROPOSED IMPROVEMENTS The proposed improvements for the 2007 Deerfield 3rd Addition Reconstruction Project include street and storm sewer construction. A detailed description of each proposed improvement is provided below. Street The proposed typical section for the streets in this project will be in accordance with the section adopted as part of the Pavement Rehabilitation Report with the exception of the aggregate base thickness. The proposed street section consists of a 28 to 32 foot wide street with concrete curb and gutter. The section generally mimics the existing pavement width plus the width of the proposed curb and gutter. One exception to the section listed above is Dodge Street where the width of the existing street will be retained. The proposed pavement and subgrade materials for all the streets consists of 12 inches of select granular borrow, 8 inches of Class 5 aggregate base, 2 inches of bituminous base course, and 1.5 inches of bituminous wear course. The proposed street section has been verified by a geotechnical investigation. The geotechnical evaluation performed by Independent Testing Technologies concluded that a 12-inch subcut of the existing silty sand will be necessary to achieve a 9-ton design. The material within the subcut area will be replaced with 12 inches of select granular borrow. The proposed street section is shown in Exhibit 6. In accordance with City Council direction to construct pedestrian facilities with new street construction, the proposed improvements also include a 6-foot wide sidewalk located on one side of each of the streets within the reconstruction area. With a 32-foot street width there are numerous locations where retaining walls will be required in order for the proposed sidewalk to fit adequately with existing grades. A 28-foot street section was also considered which alleviates some potential retaining wall locations. During final design, locations where sidewalk may not be feasible will be considered further. With the proposed sidewalk improvements, a connection to an existing sidewalk location will be made at Dodge Street. Proposed street and sidewalk locations are shown in Exhibit 7. As with the previous street reconstruction projects, the 2007 Deerfield 3rd Addition Reconstruction Project proposes to have Elk River Municipal Utilities install decorative street lights in accordance with their lighting policy as part of the project. 4
