STAFF REPORT 1 TO: Mayor Keis and Members of the City Council FROM: Eric Seaburg, P.E., City Engineer DATE: October 12, 2022 RE: Improvement Hearing for Twin Lake Boulevard Improvements City Project No. 2023-04 ACTION TO BE CONSIDERED: Motion to accept feasibility report and call for a public improvement hearing for street improvements on Twin Lake Boulevard. BACKGROUND: Twin Lake Boulevard is included in the City’s 10-year Capital Improvement Plan and 15-Year Pavement Management Plan. The roadway resides almost equally in both the City of Vadnais Heights and the City of Little Canada and is therefore a joint project. City staff has been coordinating this project with Vadnais Heights staff for the last year or so. A Cooperative and Maintenance Agreement with Vadnais Heights is currently being prepared and will be presented to the City Council at the time of the Improvement Hearing for consideration and acceptance. A feasibility report detailing the proposed projects has been prepared. The bullet points below highlight each of the proposed improvements: • Street Improvements Full-depth reclamation and paving is proposed for the roadway. Additionally, new curb and gutter will be placed on each side of the roadway. The section of roadway from Bankers Drive to Mayfair Road will be narrowed from 32’ to 28’ to help facilitate trail construction in this area. Additionally, the narrowing will act as a natural traffic calming measure. Realignment of the eastern intersection is proposed as part of the project. The exact realignment will be determined during final design with input from Vadnais Heights and Ramsey County. • Watermain & Sanitary Sewer Improvements The watermain and sanitary sewer are in good condition and are proposed to be left in place with minor improvements proposed to sanitary sewer manholes. A 400’ long watermain interconnect is proposed. This will connect the Little Canada and Vadnais Heights watermain systems. Valving for each city will remain closed during normal conditions. In the event of a water supply emergency, the valving could be opened to allow for water sharing.
