PROPOSED IMPROVEMENTS The proposed improvements for the 2007 Irving Avenue Area Street Rehabilitation Project include street, storm sewer, and watermain construction. A detailed description of each proposed improvement is provided below. Street The proposed typical section for the majority of the streets to be completely reconstructed 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 sections consist of a 32-foot, 28-foot, and 24-foot wide streets with concrete curb and gutter. These sections generally mimic the existing street widths throughout the project. One exception to the section widths listed above is the street along the School south of 5th Street along Irving Avenue which varies from 36 to 42 feet in width. North of this area along Irving Avenue the proposed street width is 32 feet. The proposed pavement section for all the streets consists of 6 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 6-iches of aggregate base will be necessary due to the existence of stable subgrade materials. The proposed street section is shown in Exhibit 7. The proposed rehabilitation of the alleys between 5th and 8th Streets will use a 12 foot wide street section utilizing the same pavement and aggregate base depths as the other portions of the reconstruction project. The alleys currently do not have curb and gutter and the proposed section also does not. The areas proposed to be milled and overlaid including Holt Avenue, 8th Street, and Gates Avenue will retain the existing street width of 40 feet. Milling operations will encompass a 6 foot swath adjacent to the curb and gutter edge. A 1.5-inch wear course will be applied over the entire road surface which will facilitate an increase crown height and better drainage. Prior to placing bituminous, existing paved areas in need of repair will be patched. Where necessary, curb and gutter and driveway apron repairs will also be made prior to the overlay material placement: 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 both sides of Irving Avenue and one side on each of the other streets within the reconstruction areas. Locations where sidewalk will not be feasible, including the alley and overlay areas, will be considered further during final design. With the proposed 5
