Staff review of the geotechnical report found clean sands, ideal for pavement support within the project area. Additionally, groundwater is not anticipated to be a concern for the street reconstruction. Proposed Improvements The bituminous curbing is proposed to be replaced with surmountable concrete curb and gutter. At driveways, a curb cut similar to what is typically placed in B-style curb will be placed to avoid a high transition from the roadway to driveways. The new pavement section will include 3.5-inches of new bituminous pavement over 4-inches of aggregate base. The aggregate base is proposed to be made of recycled reclamation. The Xenolith Street flume is proposed to be replaced with a new concrete flume, only minor grading to the existing swale to tie-in is proposed. There is not sufficient depth to convert this flume to a storm sewer inlet and run piping to the existing pond. The 159 th Lane flume is proposed to be replaced with storm sewer inlets and piping running to the existing pond,which has sufficient depth to handle the pipe system. Restoration of the impacted boulevards will include a minimum of 4-inches topsoil and hydroseed with a residential turf seed mix. Though the pavement is generally going back to the same location and elevation, driveway aprons will be replaced to match into the new concrete curb and gutter. In general,the boulevard impacts and driveway impacts will occur within 6 feet of the existing pavement. Preliminary Schedule Remaining •Council approves plans and specifications/authorizes ad for bids o February 25, 2025 • Staff Receives Bids o March 31, 2025 •Council Awards Contract to the Lowest Responsible Bidder o April 8, 2025 •Contractor Begins Construction o Spring/ Summer 2025 •Contractor Substantially Completes Construction o New bituminous pavement in-place, topsoil and seed in-place o August 30, 2025 •Contractor Final Completion o Verify final restoration; punch list created o September 30, 2025 Final plans are not attached to this case to prevent potential bidders from downloading plans attached to the case to prepare and submit their bids,rather than purchasing the plans through QuestCDN,the electronic bidding software used by the City of Ramsey. This ensures all bidders are bidding off the same set of plans, and all bidders are notified of any plan revisions (addenda) issued during the bidding process. Attached is the title sheet showing the scope of the improvements, as well as a plan sheet showing the typical sections,which includes information on the proposed pavement section. Plans are available upon request from the City Engineer. Staff proposes to bid projects separately,but to bid and award projects as close together as practical,which generally allows for a better bidding environment for the City. Notification: If Council approves plans and specifications and authorizes advertising for bids,bids will be advertised on Friday, February 28, and again on Friday, March 7, 2025, in the City's official newspaper, the Anoka Union Herald. Plans are also advertised on the QuestCDN website,which directly notifies contractors interested in bidding these types of projects. Additionally, letters will be mailed to property owners with updates on the project status. Engineering staff maintains City Improvement webpages with the most current project information. This can be found on the City website, Engineering Department page.
