TIIF: CITY OF LAKE ELMO STAFF REPORT DATE: April 1.6, 2024 REGULAR AGENDA ITEM: Accept Bids and Award Contract for the 2024 Street 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 bids and award a contract for the 2024 Street Improvements? BACKGROUND: On March 6, 2024, the City Council approved the plans and specifications for the 2024 Street Improvements project and authorized staff to advertise the project for bids. The Project was advertised on QuestCDN.com and in the Stillwater Gazette in accordance with the Minnesota Competitive Bidding requirements. The project includes street and utility improvements in two areas: Carriage Station and Jamaca Court N. Proposed improvements in Carriage Station include full depth reclamation of the street pavement; spot curb replacement; new bituminous paving; installation of a parking bay adjacent to the neighborhood Park; storm sewer and drainage maintenance; and adjustments to existing hydrants. Proposed improvements to Jamaca Court N include full depth reclamation, new concrete ribbon curb and gutter, upsizing of the existing four - inch watermain to a twelve -inch watermain, and creating a stormwater ditch and culverts along the south side of the road. The scope of improvements as designed remains generally consistent with the feasibility report recommended improvements that was approved by the City Council on November 8, 2023. Upsizing a section of watermain in the Carriage Station neighborhood is no longer included in the project scope. During the project design, it was determined that increasing the diameter of this watermain section would not significantly improve flow in the watermain system in this area. The existing hammerhead at the end of Jamaca Court will be converted into a smaller diameter cul-de-sac based on available right-of-way and review by the Public Works Director and Fire Chief.
