Consider recommending City Council approving plans and specifications and authorizing advertisement for bids for 2024 Neighborhood Pavement Overlay Improvements, Improvement Project #24-07

Purpose:
The purpose of this case is to consider recommending City Council approving plans and specifications and authorizing advertisement for bids for 2024 Neighborhood Pavement Overlay Improvements, Improvement Project #24-07.
 
Background:
The proposed 2024 – 2033 Capital Improvement Program (CIP) identifies seven (7) subdivisions for pavement overlay improvements in 2024. Street segment summaries are attached to this case.
 
Project History

• August 8, 2023, Resolution #23-182, the Ramsey City Council executed a proposal from Braun Intertec to prepare a pavement core analysis of Bowers Drive.
• November 14, 2023, Resolution #23-281, the Ramsey City Council executed a proposal from Bolton and Menk to perform a topographic survey of the pedestrian ramps within the project area.
• November 21, 2023, the Ramsey Public Works Committee considered recommending City Council order plans and specifications, additionally discussed constructing the gravel section of Basalt Street as part of these improvements.
• November 28, 2023, Resolution #23-299, the Ramsey City Council ordered plans and specifications for 2024 Neighborhood Pavement Overlays, Improvement Project #24-07.
• February 2, 2024, the Ramsey Public Works Committee considered adding a trail connection between Bowers Drive and the Riverstone South subdivision.
• March 26, 2024, the Ramsey City Council reviewed the trail connection resident survey at the Work Session, recommending to not move forward with the connection.

Proposed Improvements
Review of ground penetrating radar (GPR), as-built plans, and the Bowers Drive Mill and Overlay Evaluation performed by Braun Intertec indicates three separate mill and overlay thicknesses will be used on the various street segments.
 
Orchard Hills Townhomes subdivision does not have sufficient pavement thickness for a 2-inch mill and overlay improvements, therefore a 1.0-inch mill and 1.5-inch bituminous overlay will be used. The section of Cobalt Street between Alpine Drive and 152^nd Lane is proposed to receive a full-depth mill and fill of approximately 3.5-inches.
 
Bowers Drive will receive a full-depth mill and overlay of approximately 3.5-inches. The bituminous will be placed in 2 lifts.  Additionally, some minor base corrections are anticipated to be required.
 
All remaining subdivisions have sufficient existing bituminous thickness to perform a 2-inch mill and bituminous overlay.
 
Per typical overlay improvements, spot concrete curb and gutter repairs will be performed on damaged curb. Where feasible, the City has switched to a saw & seal method for curb cracks at a significant cost savings. This is performed on hairline cracks, without vertical displacement. For areas of bituminous curbing, repairs to the curbing are not anticipated, though the City typically updates curb adjacent to storm sewer inlets to concrete during mill and overlay projects.
 
Municipal sewer and water exist under all street segments in the project except for Bowers Drive. This project is not proposing any repairs to watermain or sanitary sewer.
 
Minor storm sewer structure repairs, typically re-grouting catch basins, is proposed. Additionally, the project proposes adding hydrodynamic separators to the storm sewer system along Bowers Drive for the two outlets to the Mississippi River. The separators are a cost-effective TSS removal device, which is used in leu of infiltration basins. Infiltration basins would require significant surface area, grading, and drainage easements which the City do not currently have.
 
Four of the townhouse subdivisions include extensive pedestrian ramps which do not meet current American with Disability Act (ADA) standards, and will require upgrades. A total of 50 pedestrian ramps were found to require upgrades, and will be replaced during construction.
 
As an alternative bid item, this project also includes constructing the gravel segment of Basalt Street south of 141^st Avenue to a fulling paved street section including concrete curb and gutter. The street will be built to a width of 36 feet, with parking on one side, and terminate in a cul-de-ac built to 66 feet in diameter. This is the largest cul-de-sac which will fit in the existing right of way. Staff reviewed options for increasing the cul-de-sac to the standard 100-foot diameter, but found it not feasible, largely due to the significant impacts on the existing commercial adjacent to the street. The pavement will be built to a 10-ton pavement strength design which is typical for industrial streets, this will be achieved by placing 4-inches bituminous on top of 6-inches aggregate base.

Full 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 plan sheet showing the typical sections, which includes information on the proposed pavement sections. Plans are available upon request from the City Engineer.

Notification is not required for this case.

Timeframe:
Staff anticipates this case will take approximately 15 minutes to present and respond to questions.
 
Observations:
The Basalt Street construction is proposed to be bid as an alternate.
 
Alternatives:
Alternative #1: Motion to recommend City Council approve plans and specifications and authorize advertisement for bids for 2024 Neighborhood Pavement Overlay Improvements, Improvement Project #24-07.
 
Alternative #2: Motion of other.

Funding for this improvement is proposed to come from Pavement Management (PM) Funds, Stormwater Utility Funds and Sanitary Sewer Utility Funds. The alternative Basalt Street construction does not qualify for Pavement Management Funds, funding would likely be Public Improvement Revolving (PIR) Funds.
 
The City collected a $10,000 Road Improvement Fee as part of the Garden View development in 2019, to be used towards a future pavement mill and overlay of 147^th Lane (Seasons of Ramsey segment). This was due to the significant street patches within 147^th Lane required for water and sewer connections as part of the development.
 
The estimated costs below include 14-percent indirect costs for administrative, engineering, finance, and legal costs.
 

• Base Street project costs                     $1,452,946.74
• Alt Bid Street project costs                 $93,264.28
  • Basalt Street
• Base Stormwater project costs            $146,068.20
• Base Sanitary Sewer project costs      $6,156.00
• Alt Bid Sanitary Sewer project costs  $570.00
  • Basalt Street
• Total Project Costs                           $1,699,005.22

Staff recommends alternative #1.
