STAFF REPORT DATE: March 19, 2024 REGULAR AGENDA ITEM: Approve Resolution Receiving Feasibility Report, Calling Hearing on Improvement, Approving Plans and Specifications, and Ordering Advertisement for Bid for the 15th Street North Improvements SUBMITTED BY: Jack Griffin, City Engineer REVIEWED BY: Clark Schroeder, Interim City Administrator Clarissa Hadler, Finance Director Marty Powers, Public Works Director Chad Isakson, Assistant City Engineer ISSUE BEFORE COUNCIL: Should the City Council accept the Feasibility Report, call a Public Hearing, approve the Plans and Specifications, and Order the Advertisement for Bids for the 15th Street North Improvements, with the Improvement Hearing to be held at the May 7, 2024 council meeting? BACKGROUND: On December 5, 2023, following a presentation on the preliminary design findings and recommendations, the City Council authorized the preparation of the feasibility report, and the plans and specifications for the 15th Street North Improvements. The project was initiated as part of the City’s annual Capital Street Improvement Program which provides for the long-term planning and management of street and transportation infrastructure throughout the city. PROPOSAL DETAILS/ANALYSIS: A Feasibility Report has been prepared to address the pavement rehabilitation improvements programmed for construction in 2024. The report serves to identify the necessary improvements, the estimated project costs, and to consider the assessment of a portion of the project costs to properties adjacent to and benefitting from the improvements. The project includes pavement rehabilitation of approx. 2,594 feet (0.49 miles) of collector roadway, consisting of a Full Depth Reclamation (FDR). The project area includes the segment of 15th Street that connects Inwood Avenue (CSAH 13) to the City of Oakdale. The roadway segment is designated as a Municipal State Aid Street (MSAS) which is eligible to receive MSA funds to pay for all or a portion of the improvements that are state aid eligible and if the improvements meet state aid design standards. The street is currently a rural section roadway that is 40-feet wide with two (2), 12-foot drive lanes and 8-foot paved shoulders. The seven (7) abutting properties are large, mostly undeveloped agricultural parcels. One property operates a commercial business. The Full Depth Pavement Reclamation (FDR) will include an 8‐inch recycled aggregate base with a new 4-inch bituminous surface. Based on the testing performed and the in‐place pavement layer thicknesses, there is sufficient material to perform FDR. The FDR approach provides a design life similar to that of reconstruction and is less expensive. It also disrupts crack patterns, reducing the potential for reflective cracking. Structurally, the overall capacity of the street will meet a 10-ton design. The pavement surface width will be reduced from 40 feet down to 36 feet, leaving a single 12-foot eastbound thru lane, a single 12-foot westbound thru lane, and 6-foot paved shoulders. Existing connecting driveways will be resurfaced up to the public right-of-way. Upon completion of the FDR improvements, the roadway will be striped consistent will existing conditions, including a double yellow centerline stipe to prohibit passing along the length of the street segment.
