As noted above some soil borings found silty sand and one found clayey sand. Though it's generally understood proper conditions can make use of this material as road subbase, previous projects with similar material have required removal and replacement and others have not required replacement. With these marginal materials we will know for sure after removal of the bituminous under the load of construction equipment. Because of this the plans include a contingency quantity for minor soil corrections, but no specific removals are called out in the plans. CulTently 177th Avenue east of Eland Street has two existing driveways, including a driveway off the end of the street. There is no turn around on this 24-foot-wide street, which is approximately 330 feet long. To add in vehicles turning around, the plans include building a 66-foot-wide cul-de-sac to extents of the existing right of way. The city owns a parcel on the north side of this street between the two residents, which provides access to the large wetland area to the north. The project includes replacing the existing metal street crossing culverts with reinforced concrete culverts and flared ends to the same location(s) and elevation(s). Only minor grading of the swales to match into the new culverts is proposed. As part of project design staff re -investigated the potential storm sewer improvements considered in 2026 due to a resident complaint of a wet basement. In 2014, when the original complaints occurred, the city experienced several extreme weather events in close succession. These high -intensity events were unusual and are not conditions that regulating agencies require communities to design for when establishing stormwater or floodplain standards. For the properties in question, the established wetland elevation is 895 feet. At the time the homes were constructed, city oversight of grading and basement placement was limited. By todays standards the city would not have recommended basements at these locations given the proximity to the wetland and the associated flood -risk considerations. Staff review did not find that a subdivision wide improvement is necessary, as there does not appear to be a significant risk of the road flooding or properties flooding out, beyond the potential for wet basements during extreme events similar to what occurred in 2014. An individual basement system, including drain tile and a sump pump is a feasible option, which staff assumes was placed or a similar action was taken by the property owners since no complaints have been received in nearly a decade. The storm sewer layout proposed in 2016 would not have a significant impact on the flooding potential, which is generated via the extensive wetland complex to the north and within the subdivision. Lowering the wetland itself would have the largest potential impact to flooding concerns, but this is not considered a feasible option, and staff does not find it necessary. Municipal utilities do not exist within the project area, extension of municipal utilities to this subdivision are not proposed as it is outside of the MUSA. Preliminary Schedule Remainine • Staff Advertises for Bids o December 11 & 18, 2026 • Staff Receives Bids o Week of January 18, 2027 • Council Awards Contract to the Lowest Responsible Bidder o January 26, 2027 • Contractor Begins Construction o Spring 2027 • Contractor Substantially Completes Construction o New bituminous pavement in -place, topsoil and seed in -place o July 31, 2027 • Contractor Final Completion o Verify final restoration; punch list created o September 3, 2027 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. Notification: if City Council approves final plans and specifications, bids will be advertised on Friday, December 11, and again on Friday, December 18, 2026, 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 directly impacted by the improvements. Engineering staff maintains
