Avenue widen the existing roadway to a maximum width of 42 feet. The proposed improvements include the reconstruction of Minnesota Avenue to a two-lane urban section with dedicated turn lanes at the Rice Street intersection. The proposed pavement section for the roadway includes 7-inches of bituminous pavement over 6.5-inches of aggregate base. The proposed roadway width will be 47 feet at the Rice Street intersection and will taper back to 34 feet to match the existing roadway. Driveways disturbed by construction will be replaced in kind within the public right-of--way with the exception of the driveway to the apartment building on the southwest corner of the intersection with Rice Street, which will be closed. County Road B2 West County Road B2 West will be reconstructed approximately 500 feet east of Rice Street and 500 feet west of Rice Street in order to tie back into the existing roadway section. The total length of the proposed street reconstruction is approximately 1,000 feet. County Road B2 West is currently a 34 to 42 foot wide two-lane urban section roadway with bituminous pavement and concrete curb and gutter. Existing turn lanes along Minnesota Avenue widen the existing roadway to a maximum width of 52 feet. The proposed improvements include the reconstruction of County Road B2 West to a two- lane urban section with dedicated turn lanes at the Rice Street intersection. The proposed pavement section for the roadway includes 7-inches of bituminous pavement over 10.5- inches of aggregate base. The proposed roadway width will be 54 feet at the Rice Street intersection and will taper back to 34 to 42 feet to match the existing roadway. Driveways disturbed by construction will be replaced in kind within the public right-of- way with the exception of the driveway to the Wonder Bakery on the north side of County Road B2 which will be removed. B. Storm Sewer Improvements The existing storm sewer system on Rice Street primarily conveys runoff from the project area to the existing drainage basin located in the southwest quadrant of the TH 36/Rice Street interchange. The proposed storm sewer improvements will maintain the existing drainage patterns. The proposed storm sewer improvements will include replacement of existing catch basins and storm sewer piping and the addition of a trunk storm sewer line along Rice Street. Proposed catch basins will be located based on Mn/DOT State Aid standards and storm sewer pipes will be sized fora 10-year storm event. C. Sanitary Sewer Improvements There are limited sanitary sewer improvements within the project area. All sanitary sewer manhole castings will be adjusted as needed along segments of Rice Street, County Road B West, Minnesota Avenue, and County Road B2 West that are being reconstructed. A 4
