June 30, 2023

The Contractor has completed all required improvements and the majority of minor punch list items. This project is now considered complete.

May 5, 2023

During the week of May 1, the Contractor removed the Highway 10 median crossover that previously provided westbound access to Bowers Drive.

During the week of May 8, the Contractor will finish restoring the new ditch section in Highway 10 where the crossovers previously existed. The new steel cable guardrail will also be installed. Final restoration and remaining sign placement are also proposed along Riverdale Drive.

December 9, 2022

A letter was mailed this morning updating impacted residents about the intersection at Riverdale Drive and Eastbound Highway 10.

This intersection allows right-in and right-out access to/from eastbound Highway 10. Westbound Highway 10 entrance to Bowers Drive and Riverdale Drive is provided from the Armstrong Boulevard interchange. 

This project includes the removal of the Highway 10 median crossover that previously provided westbound access to Bowers Drive. Due to material shortages, removing the median crossover and installing a new steel cable guardrail have been postponed until Spring 2023. In the interim, the Minnesota Department of Transportation (MnDOT) has directed the city to install a “No U-Turn” sign at the existing median crossover. This sign is anticipated to be installed within the next week or two.  

Marker signs will also be placed at the north end of the new Bowers Drive cul-de-sac to warn drivers that the connection to Highway 10 at Bowers Drive was removed and is not permissible.

November 4, 2022

During the week of October 31, the Contractor finished placing concrete pedestrian ramps, as well as topsoil and seed in the boulevard areas. The Contractor placed the final lift of bituminous pavement. The watermain trunk line casing under Highway 10 was completed as well. The extension of the trunk watermain through the new casing began and is anticipated to be complete during the week of November 7.

During the week of November 7, the Contractor is proposed to complete pavement markings and place signage along Riverdale Drive and the new Highway 10 turn lane. After pavement markings and signage are in place, the right-in/right-out from Riverdale Drive to Highway 10 will be opened. This is anticipated to occur on Tuesday, November 8.

The Highway 10 crossover removal is proposed to occur during the spring of 2023 due to the unavailability of materials. Other remaining work will include the restoration of the areas disturbed by the trunk watermain extension under Highway 10. This restoration will occur over the next several weeks, with final turf establishment anticipated to occur in the spring of 2023. Erosion control measures will remain in place as necessary until after final turf establishment.

During the week of October 31, the Contractor will finish placing concrete pedestrian ramps, topsoil and seed. The Contractor is proposed to pave the final lift of bituminous Wednesday and Thursday, November 2 & 3, weather dependent. Pavement striping will occur the following week, a minimum of 72 hours after paving. Once pavement striping occurs, the streets may be opened to all traffic.

October 25, 2022

Construction of Riverdale Drive from Llama Street to Bowers Drive is anticipated to be completed during the week of November 7. This extension of Riverdale Drive will provide a new intersection at Riverdale Drive and eastbound Highway 10, replacing the previous access to Highway 10 at Bowers Drive.

September 23, 2022

During the week of September 19, the Contractor placed a concrete curb and gutter from the Armstrong Interchange to the intersection at Highway 10. The connection to the highway has not yet been made and is not anticipated to be complete for the next several weeks. Some additional concrete work is still needed and is anticipated to be completed in the coming weeks.

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

September 16, 2022

During the week of September 12, the Contractor finished placing water and sewer services except for services on Bowers Drive. Work has been ongoing to prep the base material ahead of concrete curb and gutter placement.

During the week of September 19, the Contractor proposed to place a concrete curb and gutter from the Armstrong Interchange to Trunk Highway 10. Also, the Contractor will begin placing driveway aprons, though this work is expected to go into the week of September 26. Once the concrete curb and gutter are placed, the Contractor will begin hauling in the remaining aggregate base.

September 2, 2022

During the week of August 29, 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 go 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 5, 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 toleranced, the Contractor will haul and place new gravel. The gravel being used on this project is recycled reclamation material from other City improvements. The Contractor will also be installing water and sewer services east of Llama Street and make required storm sewer improvements in the same area. 

August 19, 2022

During the week of August 22, the Contractor is proposed to pour the lift station pad. The pad gives access to the lift station manhole 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 1. 

On Wednesday, August 17, 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 on August 22, and construction is proposed to begin August 26. 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, but 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 the delivery of the control panel.

On Friday, July 29, Bids were publicly opened for the road construction project. Staff is presenting the lowest responsible bid to City Council on Monday, August 8 for authorization to award the bid.

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.

June 10, 2022

During the previous weeks, the Contractor sub-cut for the new sanitary lift station, located in the southeast corner of the Riverstone South Addition. The Contractor has begun installing storm sewer. Next week the Contractor is anticipating finishing storm sewer construction along the project length.

During the week of June 13–17, the lift station is anticipated to be delivered. The lift station sections have been built off-site, construction of the lift station is expected to take two to four weeks. This does not include the pumps, piping, and control panels for the lift station, which still need to be delivered.

May 13, 2022

During the week of May 9–13, 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 16–20. The storm sewer structures are currently being built, and will not be ready for installation the week of May 16.

April 29, 2022

During the week of April 25–29, 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 2–6, 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. The Contractor anticipates completing the sanitary sewer along the future Riverdale Drive corridor, but will not complete the watermain. The contractor will begin installing the storm sewer, which is anticipated to takes several weeks to complete. Properties adjacent to Riverdale Drive near Llama Street may have some temporary interruptions while the watermain and sanitary sewer is being connected, and extended to the west past Llama Street.

April 22, 2022

The contractor will be hauling excess material from the project to the COR area on Friday, April 22 and Monday, April 25.

The contractor will continue sanitary sewer service the week of April 25.

As always, the City’s goal is to complete construction as quickly as practical once construction begins to minimize impacts to the public.
