Title
Adopt Resolution #21-009 Ordering Plans and Specifications for Improvement Project # 21-02, Tiger Street Reconstruction
Purpose/Background:
Purpose:
The purpose of this case is to adopt Resolution #21-009 Ordering Plans and Specifications for Improvement Project #21-02, Tiger Street Reconstruction.
Background:
City Improvement Project 21-02 proposes to reconstruct Tiger Street between Armstrong Boulevard and 173rd Avenue. The street totals approximately 2,300 linear feet (0.43 miles) in length, and is generally 24-feet wide. A figure showing the project scope is attached to this case.
On December 8, 2020, the Ramsey City Council approved the 2021 – 2030 Capital Improvement Program, which identified Tiger Street for reconstruction in 2021. On November 10, 2020, the Ramsey City Council authorized Staff to execute proposals from Bolton & Menk, Inc. for the required topographic survey, and from Chosen Valley Testing (CVT) for required geotechnical work. The CVT Geotechnical Report is attached to this case. The geotechnical report generally found clean sand below the existing bituminous and gravel pavement section, however 3 of the 10 borings found ½ foot or less of possible buried topsoil below the pavement materials. These topsoil materials are recommended to be removed prior to placement of new aggregate base and bituminous pavement.
In 2017, Tiger Street was included in the Ground Penetrating Radar (GPR) Pavement Evaluation performed by Braun Intertec. This GPR data provides bituminous and aggregate base thickness information at one-foot increments along the entire street segment. The GPR data is included in the street segment summary attached to this case. On average, 2.5 inches of bituminous pavement and 3.3-inches of aggregate base exist along this street.
Nine (9) properties have direct access to Tiger Street. Traffic counts taken by Staff in the fall of 2020 found an ADT of 573 north of Armstrong Boulevard, and 399 south of 173rd Avenue.
Tiger Street is not currently a Municipal State Aid (MSA) street but Tiger Street functions as a collector street so Staff feels this street segment would be an excellent candidate to be added to the MSA street inventory in the future. For future consideration as an MSA street, Tiger Street must be reconstructed to a 10-ton pavement design strength, which Staff feels is reasonable considering that Tiger Street functions as a collector street. To achieve a 10-ton design, the total pavement and aggregate base section depth would increase from the standard 7.5 inches (3.5 inches bituminous pavement and 4-inches aggregate base) to 10 inches (4 inches bituminous pavement and 6-inches aggregate base). With the extent of the topsoil under the existing pavement section unknown, some of this cost would be incurred with a standard city street design as topsoil removed would require back filling with new base materials.
Municipal utilities do not exist in the project area and are not proposed to be extended to the project area with this project. Stormwater runoff is directed into drainage ditches along both sides of Tiger Street. There are no known issues with stormwater management in the project area and no improvements to existing drainage ditches are proposed with this project. During design Staff will further evaluate stormwater management to determine if any stormwater improvements are necessary.
The engineer’s opinion of probable project costs for completing the proposed improvements is $380,000. The estimated costs for this project per the adopted 2021 - 2030 Capital Improvement Program (CIP) totaled approximately $360,000. However, when Staff begins the process of implementing pavement management projects a more detailed construction cost estimate is prepared including 10-percent contingency costs to account for unknowns and minor appurtenant costs. Estimated construction costs are then increased by 23-percent to arrive at estimated project costs. The 23-percent increase accounts for estimated indirect project costs for administrative, engineering, finance and legal costs needed to deliver such projects.
The street improvements proposed with this project are proposed to be funded using a combination of Pavement Management Funds and Stormwater Utility Funds as noted in the CIP. 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 #21-02, Tiger Street Reconstruction.
