Autumn Heights Street Reconstructions IP22-02
June 30, 2023
The Contractor completed the required bituminous patching and erosion fixes. The seeding placed during the patching and erosion fixes has yet to be established. The Contractor is expected to do this final turf restoration within the next two weeks. As this is the only remaining work, the project is considered complete.
May 5, 2023
City Staff has been working with the Contractor to finalize the punch list for completion. This includes looking at small pavement patchwork, erosion fixes, and final turf establishment/boulevard restoration fixes. The Contractor is anticipated to address punch list items over the next several weeks.
November 4, 2022
During the week of October 31, the Contractor completed the majority of topsoil and seed and mulch placement. City Staff will work with the Contractor to develop a punch list of small items that still need to be addressed. This punch list will be completed during the spring of 2023.
October 28, 2022
On Friday, October 28, the Contractor placed the final lift of bituminous pavement. During the week of October 31, the Contractor will finish placing topsoil, seed, and mulch. The seeds being placed are anticipated to be dormant over the winter and grow in the spring of 2023, as we are now past the growing season. Erosion control is also proposed to be left in place over the winter and will be removed in the spring of 2023 after the new turf has been established.

During the week of October 10, the Contractor began the soil corrections on 167th Lane east of Armstrong Boulevard. The Contractor also toleranced the aggregate base on the west side of Armstrong Boulevard in preparation for new bituminous pavement.
During the week of October 17, the Contractor is scheduled to place the new bituminous pavement on the streets west of Armstrong Boulevard on Thursday, October 20. Residents are asked to avoid using the streets as much as possible and be cautious of construction vehicles. The new pavement can be driven on after being rolled. Still, there may be 15-20 minutes during which access to individual driveways or streets will be unavailable until the rolling process is complete. On the east side of Armstrong Boulevard, the base course will tentatively start to be paved on Friday.
The Contractor is scheduled to finish the soil corrections on 167th Lane. The Contractor is proposing to start replacing the concrete driveways on the streets east of Armstrong Boulevard. Once the concrete is placed, it may not be driven on for five days, so residents should plan accordingly. Additionally, the Contractor will begin tolerancing the aggregate base on the east side of Armstrong in preparation for new bituminous pavement.

The Contractor has installed all the new culverts crossing the streets, reclaimed the existing bituminous and aggregate base, and hauled off the excess aggregate material.
During the week of October 10, the Contractor is proposed to perform the soil corrections on 167th Lane east of Armstrong Boulevard. The Contractor proposes to perform this work one lane at a time to keep the street open to traffic, but Staff recommends avoiding 167th Lane while the Contractor is performing the work if possible. The Contractor is proposing to begin placing new pavement as well. This will start on the streets west of Armstrong Boulevard. The streets east of Armstrong Boulevard will unlikely receive bituminous pavement next week, but this will depend on how quickly the soil corrections and aggregate tolerances go.

During the week of September 19, the Contractor began work on-site. The driveways set for removal were marked and saw cut. The proposed removals will occur simultaneously with bituminous removal in a few weeks. The silt fence was proposed to be placed but was pushed back to Monday, September 26.
During the week of September 26, the Contractor is proposed to remove and replace the culverts crossing the streets. The streets west of Armstrong Boulevard are proposed to be reclaimed (this process is grinding up the existing bituminous and underlying aggregate base). A roller follows the reclaimer, and after rolling the surface, it will be drivable. A concrete curb and gutter are proposed to replace the existing bituminous curb on 167th Lane. This work is also slated to occur during this week.

On Friday, September 16, the City held a pre-construction meeting with GMH Asphalt Corporation, the Contractor performing the improvements. During the meeting, City Staff and the Contractor reviewed the proposed schedule and discussed the construction procedure, processes, and requirements. A letter with the project schedule and other relevant information is being mailed to residents impacted by the project and may be seen here. The Contractor is proposing to begin work on Thursday, September 22. This initial work will include placing traffic control devices, erosion control, and saw-cutting driveway aprons proposed to be replaced as part of the project.
August 12, 2022
On Monday, August 8, the City Council awarded the project to the lowest responsible bidder, GMH Asphalt Corporation of Chaska, Minnesota. City Staff is working with the Contractor to execute the contract and to schedule a pre-construction meeting. This generally takes two to three weeks to do. At the pre-construction meeting, the Contractor will provide information to the City, including contact information for themselves and their subcontractors, a detailed project schedule, proposed work hours and construction methods, traffic control plans, and other construction-related information. An update letter was sent to residents affected by this project and may be viewed here. Once the pre-construction meeting is held, another update, including a detailed project schedule, will be sent out.

The City staff is working on plans for this reconstruction project and would like to encourage impacted residents to contact us with questions or input.
On July 13, 2021, the Ramsey City Council ordered the City Engineer to request proposals for Topographic Survey, Geotechnical Evaluations, and Utility Testing for proposed 2022 Pavement Management Program (PMP) projects, including IP 22-02. On August 8, 2021, the Ramsey City Council awarded a proposal to Hakanson Anderson for a topographic survey and Haugo Geotechnical Services for a geotechnical report of the project area.
Engineering Staff has completed an initial review of the topographic survey and geotechnical report, determining the requirements of the proposals have been met. The first assessment of the geotechnical report revealed sub-base materials consisting primarily of poorly-graded sand and poorly-graded sand with silt. These materials are generally well suited for street construction, though silty materials can be susceptible to frost-heave, mainly when the soils cannot drain. The staff has done field visits of the site, and the existing pavement appears not to have been negatively impacted by the silty materials for the majority of the project. However, 168th Lane, southeast of 167th Lane, may require some corrections. The geotechnical report revealed groundwater closer to the pavement surface, approximately five feet below at the time of soil boring, and these wet, less drainable soils were likely a factor in the pavement appearing to rut, which is differential settling across the pavement surface. The report and any proposed improvements will be explored further during the project design.
The streets within the Autumn Heights subdivision were included in the Ground Penetrating Radar (GPR) Pavement Evaluation performed by Braun Intertec. This data provides bituminous and aggregate base thickness information.
The streets within Autumn Heights are 24 feet wide, rural section streets. These streets are proposed to be reconstructed to the City’s current standard residential street design, with a minimum of 4 inches of aggregate base and 3.5 inches of new bituminous pavement. Due to the underlying soils, Staff proposes using the full-depth reclamation process, removing excess reclamation material, leaving a minimum of 4 inches to be re-used as an aggregate base, and placing 3.5 inches of new bituminous pavement on top. The proposed street alignment and profile will generally be unchanged.
Municipal sanitary sewer and watermain do not exist within the project area and are not proposed to be extended with this project. Stormwater runoff is handled through the existing drainage swales along both sides of the streets, with street crossing culverts connecting the ditches. Stormwater is generally carried south towards Trott Brook. The staff is unaware of drainage issues or concerns with the existing drainage swales, which would require re-grading. Beyond touch-up work needed to replace the street crossing culverts, grade changes to the swales have yet to be proposed. However, this will be reviewed during project design.
Estimated project costs per the proposed 2022–2031 CIP are $984,000. Estimated costs include 23 percent indirect costs for administrative, engineering, finance, and legal. Staff created the plans and specifications for the project in-house as part of their regular duties.
The street improvements proposed with this project are identified in the City’s current 10-year CIP and can be funded using a combination of Pavement Management Funds and Stormwater Utility Funds. This project would best be constructed as a stand-alone project and is necessary, feasible, and cost-effective from an engineering standpoint, and can be constructed as proposed herein.
Funding for this improvement is proposed from the Pavement Management Fund and Stormwater Utility Fund.
- (PMP) Street Project Cost $895,000
