are proposed along 164th Avenue, the northern portion of Germanium Street, and 161 st Avenue connecting into the Estates of Silver Oaks subdivision. Additionally, the southern portion of Germanium Street and adjacent 161st Lane was found to have a high-water table, which seasonally impacts the strength of the pavement section. The project proposes to raise the elevation of the pavement approximately 1-foot to allow the pavement section to be dry during seasonally high-water. In the areas not requiring corrections, Staff is proposing to use a pavement section made up of 6-inches in -place reclamation material below 3.5-inches of new bituminous pavement. This project proposes to remove the stub street at the corner of Dysprosium Street and 161 st Lane, and create a true comer, since the development of the adjacent Scout Camp property is not currently proposed to occur. In general, the current swales along the streets are not proposed to be re -graded as part of this project. Due to the nature of subsoil corrections, and raising the profile of the pavement, some areas of the project will have impacts to the in -slopes between the pavement and bottom of the swales. No changes to the current drainage patterns are proposed. The existing culverts crossing the streets are proposed to be removed and replaced, this is to ensure the culverts will last at least through the proposed 60-year design life of the street. Due to the subsoil corrections, drain tile will be added in the low areas to properly drain the pavement subbase. The drain tile is proposed to drain into the existing swales.

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. The proposed improvements are designated as City Improvement Project #23-05, Barthel's Rum River Acres 2nd Street Reconstructions. Notification: If Council approves plans and specifications and authorizes advertising for bids, bids will be advertised on Friday, April 28, and again on Friday May 5, 2023, in the City's official newspaper, the Anoka Union Herald. Additionally, letters will be mailed to property owners with updates on the project status.
