Pavement History
Sunwood Drive and Waco Street were constructed in 1985 and 1992 respectively. Pavement maintenance has included crack seal / seal coat improvements in 1992 (Sunwood Drive only), 2006, and 2013. Maintenance crews have performed patching over the last several years, including extensive spray patching. No pavement overlay improvements have been performed on these street segments. 2021 PASER values were 3 for Sunwood Drive and 3 for Waco Street.
 
Ground Penetrating Radar (GPR) was performed on the street segments. Bituminous pavement thickness was found to have an average thickness of 4.20 inches on Sunwood Drive and 3.9 inches on Waco Street. GPR was not able to reliably identify the aggregate base thickness, however, the soil borings performed as part of the geotechnical report found an average of 6.4 inches.
 
Proposed Improvements
Sunwood Drive and Waco Street are Municipal State Aid (MSA) streets, and must comply with State Aid design requirements. MSA design requires these to be a 10-ton design. Based on the traffic counts performed in 2021 (1,800 ADT Sunwood, 580 ADT Waco), the required pavement section is 5-inches aggregate base and 4-inches bituminous pavement.
 
Staff review found existing pedestrian ramps within the project area did not meet current ADA requirements, and therefore will need to be removed and replaced. The concrete curb and gutter were found to generally be in good condition, and only spot repairs are proposed. Staff is proposing minimal impacts to the existing bituminous trail with the project beyond what is required for matching into the new pedestrian ramps. The south leg of trail at the intersection of Sunwood Drive and Trunk Highway 47 is proposed to be straightened, the current 90-degree corner is a hazard for plowing.
 
Review of the sanitary sewer and watermain did not find issues requiring repair. The City will be placing inflow and infiltration (I & I) barriers on the sanitary sewer manholes with this project. The City received I & I grant funding from the Metropolitan Council of Environmental Services for this work, which will reimburse the City for the costs associated with the I & I barriers.
 
Televising of the storm sewer system found more issues than anticipated, and will require removal and replacement of six storm sewer structures and their connecting pipes. The majority of this work will be concentrated at the intersection of Sunwood Drive and Zuni Street.
 
The current pavement marking layout meets State Aid standard, and the road is proposed to be marked back to the existing layout.
 
Generally, impacts to boulevards will be minor, just as necessary for removal and replacement of concrete curb and gutter, pedestrian ramp improvements, and excavation required for the storm sewer repairs.
 
Anticipated Construction Process

• Install traffic control measures
  • These are maintained throughout the project
  • Layout of traffic control may be adjusted to accommodate construction periodically
• Install I & I barriers on sanitary manholes
• Install erosion control measures
• Full-depth reclamation of existing bituminous pavement and aggregate base
• Storm sewer repairs
• Project removals (spot curb and gutter, pedestrian ramps, driveways as needed)
• Place new concrete curb and gutter and pedestrian ramps (5 to 7-day cure time)
• Remove excess reclaim material, shape and compact 5 inches of remaining material
  • Excess reclaim is stockpiled and will be used on future City projects
• Place first lift of new bituminous pavement
• Finish any trail and driveway repairs
• Restore the boulevard in any impacted areas
  • 4 inches topsoil, seed and hydro-mulch
• Place the final lift of new bituminous pavement
  • Remove traffic control measures as allowed
• Place all pavement marking, must wait 72 hours after paving
• Erosion control measures are removed after restoration has been completed

The proposed improvements are designated as City Improvement Project #22-01, Sunwood Drive and Waco Street Reconstruction.

Advertisements were published in the Anoka Union Herald and in Finance & Commerce on April 1 and April 8, 2022. Bids were also advertised on-line on Quest CDN.
 
Letters will be mailed to property owners with updates on the project status. Engineering Staff maintains a project webpage, which will be updated as new information is made available throughout the project.

Alternative #1 – Motion to adopt Resolution #22-115 accepting bids and awarding a construction contract for Sunwood Drive and Waco Street Reconstructions, Improvement Project #22-01, to Novco, Inc. for the bid in the amount of $560,896.85.
 
Alternative #2 – Motion to deny adoption of Resolution #22-115 at this time.

On May 19, 2022 a total of three (3) bids were received, opened, and tabulated and the following bids were found to comply with the advertisement for bids.
 

CONTRACTOR	TOTAL BID
Novco, Inc.	$560,896.85
North Valley, Inc.	$568,293.90
Asphalt Surface Technologies Corp.	$709,380.90
Engineer’s Estimate	$447,283.25

 
The bid of Novco, Inc. of Elk River, Minnesota in the amount of $560,896.85 for the total bid for construction of said improvement in accordance with the approved plans and specifications and advertisement for bids, is the lowest responsible bid. Adding indirect costs for administrative, engineering, finance and legal costs in the amount of 23-percent brings total project costs to $689,903.13.
 
Per the final plans and specifications, estimated construction costs were $447,283.25. After adding 23-percent indirect costs, estimated project costs totaled $509,902.91.
 
The low bid is 25-percent more than the engineer’s estimate. The engineer’s estimate reflects bid item unit costs from early year projections. Because this estimate was calculated prior to opening bids on other City improvements, Staff did not adjust the unit costs based off of the more recent data. In addition to the higher than estimated bituminous pavement, hauling, and aggregate base construction costs observed with earlier bids, the bid prices received for this project for mobilization of equipment and iron also increased significantly.
 
Funding for this improvement is proposed to come from MSA Funds, Stormwater Utility Funds, and Sanitary Sewer Utility Funds. Sanitary Sewer Funds will be reimbursed through an Inflow & Infiltration Grant.
 

• Street Project Costs                $599,824.08
• Storm Sewer Project Costs     $79,132.05
• Sanitary Sewer Project Costs $10,947.00
• Total Project Costs               $689,903.13

 
Hakanson Anderson proposes to provide construction staking in a total not-to-exceed amount of $3,055.00. These costs are included in the 23-percent indirect costs. Staff feels these costs are reasonable based on the scope of the proposed improvements and required staking and recommends accepting the proposal, which is attached for reference.
 
City Staff proposes to administer and inspect construction.
 
Plans and specifications were prepared in-house as part of Staff’s normal duties.
 
Outside costs incurred to date as engineering indirect costs include:
 

• $4,920.00 for Haugo Geo Technical Services, LLC to supply a geotechnical report of the project area.
• $12,310.30 for Hydro-Klean, LLC to perform sanitary sewer and storm sewer cleaning and supply reports of pipe conditions within the project area.
• $435.00 for Water Conservation Services, Inc. to perform a water leak test on the watermain system in the project area.
• $2,500.00 for Hakanson Anderson to collect topographic survey of the project area.

Staff recommends Alternative #1.
