CC Regular Session Meeting Date: 10/26/2021 Submitted For: Joe Feriancek, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works Information 5. 13. Title: Adopt Resolution #21-299 Ordering Plans and Specifications for Improvement Project #22-01, Sunwood Drive and Waco Street Reconstruction Purpose/Background: 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 150th 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 150th 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
