Some additional concrete work is still needed, and is anticipated to be complete in the coming weeks.

During the week of September 26th, the Contractor is proposed to shape, compact, and tolerance the aggregate base prior to the first lift of bituminous pavement being placed. This work is expected to take the entire week.

During the week of August 29th, the Contractor placed the access to the new sanitary sewer lift station. Some components of the lift station control panel have not been delivered, and the lift station cannot become live until they are installed.

Work has begun on the street reconstruction portion of the project, including reclamation of the existing pavement and aggregate base between the Armstrong Interchange and Llama Street.  The existing driveway aprons in this area have also been removed and temporarily ramped for continued access to the adjacent businesses.

During the week of September 5th, the Contractor is proposed to begin tolerancing the subgrade in the new Riverdale Drive extension between Llama Street and Bowers Drive. After the subgrade has been tolerance, the Contractor will haul and place new gravel. The gravel being used on this project is recycled reclamation material from other City improvements.

During the week of August 22nd the Contractor is proposed to pour the lift station Pad. The Pad gives access to the lift station manholes covers, as well as the lift station control panel. Once the pad is placed and the concrete cures, the control panel will be placed and hooked up. The lift station is proposed to be in operation on September 1st

On Wednesday, August 17th, the pre-construction meeting was held for the Riverdale Drive reconstruction and roadway extension project, which is being performed by Douglas-Kerr Underground under a separate contract from the Riverdale Drive utility extension.  A notification letter will be mailed to impacted residents closer to the actual construction start date. Traffic control devices are proposed to be installed Monday, August 22nd, and construction is proposed to begin Friday, August 26th. The initial focus of construction will be to finish the Riverdale Drive extension from U.S. Highway 10/169 to Llama Street, and make the new connection to Bowers Drive. This is necessary to re-route traffic from Bowers Drive before the access to Highway 10/169 is removed and replaced with a cul-de-sac.

August 5, 2022

The new lift station internal piping and pumps have been installed, the control panel for the lift station is yet to be delivered. It’s anticipated that the lift station will be operational in a month, but this is dependent on delivery of the control panel.

July 22, 2022

To date all water main, sanitary sewer, and storm sewer lines and structures have been installed along the extension of Riverdale Drive between Llama Street and Bowers Drive. The new lift station located in the southeast corner of the Riverstone South development has been installed. The lift station internal piping, pumps, and control panels are yet to be delivered and are the only items remaining for the utility extension project.

The new street, including aggregate base, curb and gutter, pedestrian trail, and new bituminous pavement will be constructed under a separate contract and is currently out for bids. This project will include reconstructing the existing Riverdale Drive between the Armstrong Boulevard interchange and Llama Street, extending the new street between Llama Street and Bowers Drive, constructing a right in, right out connection to Trunk Highway 10 with associated improvements on Highway 10, removing the existing Bowers Drive connection to Highway 10 and replacing it with a cul-de-sac.

During the week of May 9th – 13th, the Contractor finished installing the new force main sanitary sewer. This force main sewer was tied into the new force main sewer constructed with the Riverstone South subdivision. The force main carries sanitary sewer from the proposed lift station, to the gravity trunk sanitary sewer, connecting it to the rest of the City’s sanitary sewer system. The dewatering for the proposed lift station was installed, but the dewatering pumps and generators will not be started for approximately 10-days.

Besides maintaining erosion control measures, no work is proposed on-site during the week of May 16th – 20th. The storm sewer structures are currently being built, and will not be ready for installation the week of May 16th.

During the week of April 25th – 29th, the Contractor installed watermain and sanitary sewer between Bowers Drive and the future Snowy Owl Street connection of the Riverstone South Development. A temporary bituminous patch was placed on Bowers Drive after the sanitary sewer manhole was set. Residents should expect this patch to remain in-place until the Riverdale Drive street project begins later this summer. 

During the week of May 2nd – 6th, the Contractor is proposing to connect to the existing watermain and sanitary sewer in Riverdale Drive just east of Llama Street, and install the utilities to the west towards Bowers Drive.

On Tuesday, March 22, 2022, Ramsey City Council awarded a construction contract to Douglas-Kerr Underground L.L.C. of Mora, Minnesota for Improvement Project #22-05, Riverdale Drive Trunk Utility Improvements. At the same time City Council approved a proposal from Bolton & Menk for construction related services for the same project. Improvement Project #22-05 extends trunk water and sanitary sewer between Llama Street and Bowers Drive, as well as constructs a sanitary sewer lift station. Douglass-Kerr’s bid of $2,163,890.22 was the lowest of eleven (11) bids received at the bid opening, which was held on March 11, 2022. Including 23-percent indirect costs for administrative, engineering, finance and legal costs, the total project costs will be about $2,661,585 which is 19.4-percent less than the engineer’s project cost estimate. Bolton & Menk has begun working with Douglass-Kerr to get the required documents in order and set a pre-construction meeting. The project schedule will be determined by Douglass-Kerr, and presented to the City at the pre-construction meeting.

Plans and specifications for Improvement Project #20-05 Riverdale Drive Extension between Llama Street and Bowers Drive are currently under development by Bolton & Menk. Improvement Project #20-05 will construct the new roadway and off street trail, construction is planned to occur in the summer/fall of 2022. In the meantime, please feel free to contact City Engineer Bruce Westby with questions on either project, by email bwestby@cityoframsey.com or by phone at 763-433-9825.

Project Information

The extension of Riverdale Drive between Llama Street and Bowers Drive is needed to support development in the immediate area. During the summer/fall of 2022, Riverdale Drive will be extended between Llama Street and Bowers Drive to provide a safe access route with sufficient capacity to serve the new developments and also the existing residential properties along Bowers Drive.  Click here to view a figure showing the proposed alignment of Riverdale Drive from Llama Street to the new connection to Highway 10, east of Bowers Drive, as well as the new street segment connecting Riverdale Drive to Bowers Drive.  Bowers Drive will be disconnected from Highway 10 to prevent people from accidentally driving south on Bowers Drive after turning off of Highway 10/169. Anyone wishing to access Bowers Drive will instead have to make a decision to turn onto Bowers Drive. This design was driven by comments made by residents of Bowers Drive.  

In March of 2022, Capstone Homes will begin construction on the first phase of Riverstone South, a 244-unit residential development east of Bowers Drive and south of U.S. Highway 10/169.  Future commercial development is also proposed on the parcels between U.S. Highway 10/169 and the proposed extension of Riverdale Drive. These developers are sharing in the costs to extend Riverdale Drive from Llama Street to Bowers Drive, and will pay trunk utility fees upon development to pay their share of the trunk utility improvements serving their developments with sewer and water. 

The trunk utilities will be constructed in advance of the street and trail improvements.  The trunk utility improvement project, Improvement Project #22-05, is currently out for bids with the bid opening scheduled for March 11th.  The construction plans and specifications for the street and trail improvements, Improvement Project #20-05, are still under development. Updated information on each project will be added to the respective project web page as the projects continue to develop.  In the meantime, please feel free to contact City Engineer Bruce Westby with questions on either project, bwestby@cityoframsey.com or 763-433-9825.
