Public Works Committee Meeting Date: 03/15/2022 Submitted For: Joe Feriancek, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works 5.2. Title: Consider Recommending City Council Approving Plans and Specifications and Authorizing Advertisement for Bids for 2022 Neighborhood Pavement Overlay Improvements, Improvement Project #22-04 Purpose/Background: Purpose: The purpose of this case is to consider recommending City Council approving plans and specifications and authorizing advertisement for bids for 2022 Neighborhood Pavement Overlay Improvements, Improvement Project #22-04. Background: City Improvement Project 22-04 proposes to overlay the streets within the Sunfish Lake Business Park 2nd Sunflower Ridge, Tiger Meadows, and The Ponds of Ramsey subdivisions. The streets total approximately 14,200 linear feet (2.69 miles) in length, vary in width between 32 and 42 feet, and are urban sections. A street segment summary is attached to this case. Project History • 2022 — 2031 Capital Improvement Program — listed as street overlay for 2022 • August 10, 2021 City Council accepted proposals for topographic survey . October 26, 2021 City Council ordered plans and specifications Pavement History The streets within the subdivisions were generally built between 2002 and 2003. Pavement maintenance has included 2 crack seal / seal coat improvements. 2021 PASER values were 7 for all street segments. Ground Penetrating Radar (GPR) was performed on some of the street segments within the project area, and are summarized in the street segment summary. Proposed Improvements Based on Staff review of the existing pavement sections, and condition of the existing pavements, a mill and overlay of the existing pavement is appropriate. The proposed mill and overlay will vary between 1.5 and 2 inches thick dependent upon the existing pavement thicknesses. Staff review found the existing pedestrian ramps within the project area did not meet current ADA requirements, therefore all pedestrian ramps within the project area will need to be removed and replaced. The concrete curb and gutter in the project area were found to generally be in good condition, and only spot repairs are proposed. Minor repairs to the existing storm sewer structures are proposed with this project, the majority of which are grouting the existing adjustment rings and pipe inverts. A few storm sewers catch basins will require resetting due to settling. The City will be placing inflow and infiltration (UI) barriers on the sanitary sewer manholes with this project. The City received an MCES I/I Grant for this work, which will reimburse the City for the costs associated with the 1/1 barriers. Build Process
