During project design, Staff noted that several driveways within the subdivision do not have culverts. In essence, <br />the ditch between these driveways do not have an outlet. Staff estimates approximately 4,650 lineal feet of ditches <br />would require re -grading, as well as installation of 31 driveway culverts. Staff estimates it would cost <br />approximately $200,000 to re -grade the drainage ditches along the roadway, which currently don't outlet. Because <br />of the fast draining soils found in the project area, Staff believes stormwater runoff infiltrates within the ditches <br />before overtopping driveways. Additionally, Staff is not aware of resident complaints in relation to drainage of <br />the roadway ditches within the subdivision. Staff is recommending to not include additional drainage ditch <br />improvements as part of this project, since it appears the water infiltrates before causing hazards for the residents. <br />if it is determined that a drainage improvement project is necessary in the future, this work could be performed as <br />a stand-alone project. Because the ditch work is generally different from the scope of the roadway project, <br />additional project savings by combining improvements would be minimal. An exhibit is attached showing the <br />drainage concern areas. <br />Preliminary Schedule Remaining <br />• Council approves plans and specifications / authorizes ad for bids <br />o June 27, 2023 <br />• Staff receives bids <br />o July 21, 2023 <br />• Council awards contract to the lowest responsible bidder <br />o July 25, 2023 <br />• Contractor begins construction <br />o August 2023 <br />• Contractor substantially completes construction <br />o September 29, 2023 <br />• Contractor final completion (verify final restoration, punch list created <br />o October 13, 2023 <br />Final plans are not attached to this case to prevent potential bidders from downloading plans attached to the case <br />to prepare and submit their bids, rather than purchasing the plans through QuestCDN, the electronic bidding <br />software used by the City of Ramsey. This ensures all bidders are bidding off the same set of plans, and all <br />bidders are notified of any plan revisions (addenda) issued during the bidding process. Attached is the title sheet <br />showing the scope of the improvements, as well as a plan sheet showing the typical section, which includes <br />information on the proposed pavement section. Plans are available upon request for the City Engineer. <br />Timeframe: <br />Staff estimates up to 10 minutes will be needed to present this case and respond to questions. <br />Observations/Alternatives: <br />Alternatives: <br />Alternative #1, motion recommending City Council approving plans and specifications and authorizing <br />advertisement for bids for Whispering Pines Estates Plat 3 Street Reconstructions, Improvement Project #23-10. <br />Alternative #2, motion of other. <br />Funding Source: <br />Funding for this improvement is proposed to come from Pavement Management Funds and Stonnwater Utility <br />Funds. <br />Staff has completed an estimate based on the final plans and anticipated 2023 construction costs, with a total <br />estimated project cost of $721,855.54, which includes 23-percent indirect costs for administrative, engineering, <br />finance, and legal costs. <br />
