Adopt Resolution #21-299 Ordering Plans and Specifications for Improvement Project #22-01, Sunwood Drive and Waco Street Reconstruction

Purpose:
The purpose of this case is to adopt Resolution #21-299 Ordering Plans and Specifications for Improvement Project #22-01, Sunwood Drive and Waco Street Reconstruction.
 
Background:
City Improvement Project 22-01 proposes to reconstruct Sunwood Drive between Trunk Highway 47 and Waco Street, and Waco Street between Sunwood Drive and 150^th Avenue. The streets total approximately 2,500 linear feet (0.48 miles) in length, and are 45 feet wide back of curb to back of curb. A figure showing the project scope and a street segment summary is attached to this case.
 
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 projects, including IP 22-01. On August 8, 2021, the Ramsey City Council awarded a proposal to Hakanson Anderson for topographic survey, and Haugo Geotechnical Services for a geotechnical report of the project area. On August 24, 2021, the Ramsey City Council awarded a proposal to Hydro-Klean, LLC for cleaning and televising the sanitary and storm sewer, and Water Conservation Services, Inc. for watermain leak testing 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 initial review of the geotechnical report revealed sub-base materials which are conducive for good compaction and suitable for both utility installation and street construction. The report will be further consulted by Staff during project design.
 
Sunwood Drive and Waco Street were included in the Ground Penetrating Radar (GPR) Pavement Evaluation performed by Braun Intertec. This data provides bituminous and aggregate base thickness information. The GPR data is included in the street segment summary attached to this case.
 
Sunwood Drive and Waco Street are Municipal State Aid (MSA) streets, and must be designed to MSA standards. Waco Street between Sunwood Drive and 150^th Avenue varies from the segment widths north and south, which are a 32-foot urban section to the south and a 24-foot rural section to the north. If parking is removed on one side of the street, the pavement width can be reduced to between 32 and 34 feet as measured to the face of curb. Staff proposes to compare the estimated cost of leaving Waco Street at it's current width versus the upfront, and expected life cycle costs, to reduce the width. Staff will share this cost comparison information with the City Council at a future meeting and will request direction on which option to move forward. If the option to reduce the width is moved forward, a No Parking Resolution would be required prior to MSA project approval.
 
These streets will also be required to meet an MSA 10-ton design standard. Based off traffic counts taken by Staff of 1,800 Average Daily Vehicles (ADT) on Sunwood Drive and 600 ADT on Waco Street, the proposed pavement section will be approximately 9 inches thick; 5 inches new bituminous pavement and 4” aggregate base. These numbers will be confirmed during project design, as a closer look is taken at the geotechnical report and GPR summary. The proposed reconstruction process is to use full-depth reclamation, re-use the reclamation material as aggregate base, place new bituminous pavement on top after removing excess reclamation material. With this process the existing concrete curb and gutter would remain in-place and spot repairs would be performed. If the option to narrow the street width of Waco Street is chosen, additional concrete curb and gutter removals and driveway extensions would be required, as well as additional turf restoration.
 
Municipal utilities exist in the project area including water, sewer, and storm sewer systems. There are no anticipated repairs to the sanitary sewer or watermain. The sanitary sewer was cleaned and televised, and the watermain was leak tested, with no leaks discovered. There are two storm sewer systems within the project area. A local system which directs stormwater runoff into catch basins along the streets and through piping into the stormwater pond located at the northeast quadrant of Sunwood Drive and Trunk Highway 47. A trunk storm water system takes runoff from the pond and directs it through storm manholes and larger pipe, which eventually outlets to the Rum River, east of Waco Street. Initial review of the storm sewer televising indicates some minor pipe repairs will be necessary. Additionally, during design Staff will evaluate the need of any improvements to the river outlet, focusing on storm water quality controls.
 
Estimated project costs per the proposed 2022 – 2031 CIP are $405,000. Estimated costs include 23-percent indirect costs for administrative, engineering, finance and legal costs. Staff proposes to create the plans and specifications in-house as part of their normal 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 MSA Funds, and Storm Water 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.
 
The proposed improvements are designated as City Improvement Project #22-01, Sunwood Drive and Waco Street Reconstruction

Notifications are not required for this case.

Motion to adopt Resolution #21-299 ordering plans and specifications for improvement project #22-01, Sunwood Drive and Waco Street Reconstruction.

Funding for this improvement is proposed to come from the MSA Fund and Stormwater Utility Fund.
 

• (MSA) Street Project Cost      $368,000
• Storm Sewer Project Cost      $37,000
• Total Estimated Project Cost  $405,000

Staff recommends adopting Resolution #21-299 ordering plans and specifications for improvement project #22-01, Sunwood Drive and Waco Street Reconstruction.
 
The Ramsey Public Works Committee reviewed this project on October 19, 2021. The committee recommended City Council authorization ordering Staff to prepare plans and specifications. Additionally, the committee recommends Staff bring a case forward to City Council at a later date to decide between the alternatives of reducing the width of Waco Street or leaving the width as existing. Staff plans to present this case at a November City Council meeting.

Adopt Resolution #21-299 ordering plans and specifications for improvement project #22-01, Sunwood Drive and Waco Street Reconstruction.
