Existing Conditions Xkimo Street between 142nd Avenue and Saint Francis Boulevard(TH 47) is 42 feet wide urban section with storm sewer catch basins in the curb line. Average daily traffic is approximately 2,050 vehicles. The west side of Xkimo Street is approximately 50-percent developed commercial, including a business park and gas station. The east side and adjacent cul-de-sacs are single-family residential. The Riversbend 3 rd,4th, and Plaza subdivisions are 31 feet wide urban section. Sewer and water exist under all the streets within the project area. During project design, these utilities were televised. Based on the televising, minor storm sewer repairs have been incorporated into the plans. Two commercial properties on the west side of Xkimo Street are currently in the development process. Staff has coordinated necessary utility connections with the developments as part of this project,this will avoid future impacts to the City infrastructure when construction begins on those projects,which is anticipated to occur following the street reconstruction. Proposed Improvements This project proposes to follow the typical full-depth reclamation(FDR) design process. The majority of concrete curb and gutter was found to be in good condition, and generally only spot curb and gutter replacement will be performed. This includes removal and replacement of the concrete median splitting Xkimo Street on the east leg of the Saint Francis Boulevard intersection. Complete removal of the median was considered; however, it is required to remain for traffic safety concerns. Additionally, many of the concrete valley gutters at crossing streets and drives were found to require replacement. Xkimo Street is a Municipal State Aid(MSA) street and must comply with State Aid design requirements. MSA design requires a 10-ton pavement strength design. This is proposed to be achieved using 6-inches of recycled full-depth reclamation aggregate base under 4.5-inches of new bituminous pavement. This same section will be used for the Xkimo Street cul-de-sac,which serves several commercial sites, and will handle more truck traffic than typical local streets. The local streets including 143rd Avenue, 143rd Lane, and Xkimo Court will be reconstructed to the current City standard pavement design. This is proposed to be achieved using 4-inches of recycled full-depth reclamation aggregate base under 3.5-inches of new bituminous pavement. An existing concrete sidewalk runs in the boulevard along the west side of Xkimo Street between 142nd Avenue and Saint Francis Boulevard. The project proposes spot repairs to the sidewalk where it is damaged and where trip hazards occur. Additionally, 6 pedestrian ramps will be replaced to bring them up to current ADA requirements. One existing pedestrian ramp,near Xkimo Court, is proposed to be removed. This is an unsafe crossing location, and pedestrians will be routed to the signalized crossing at Saint Francis Boulevard. Stormwater runoff along the streets is collected by storm sewer inlets along Xkimo Street,which eventually flow into a pond adjacent to Rivers Bend Park, and eventually into the Rum River. Only minor repairs to 3 damaged sections of pipe and structures are proposed with this project. Repairs are not proposed to municipal water with this project. Sanitary sewer repairs include replacing the existing sanitary sewer castings,which are no longer specified.
