Consider Recommending City Council Authorization to Prepare Plans and Specifications for 2022 Pavement Management Program Projects.

Purpose:
The purpose of this case is to consider recommending City Council authorization to prepare plans and specifications for 2022 Pavement Management Program Projects.
 
Background:
The proposed 2022 – 2031 Capital Improvement Program (CIP) identifies three reconstruction projects and two overlay improvements for 2022;
 
IP 22-01 Sunwood Drive and Waco Street Reconstruction (MSA)
IP 22-02 Autumn Heights Street Reconstructions
IP 22-03 2022 MSA Pavement Overlay Improvements (MSA)
IP 22-04 2022 Neighborhood Pavement Overlay Improvements
IP 22-06 Wood Pond Hills 2^nd – 5^th Street Reconstructions
 
Street segments summaries and an Improvement Project Map are attached to this case.
 
Preliminary Design
On July 13, 2021, City Council passed Resolution #21-194, Ordering the City Engineer to request proposals for Topographic Surveys, Geotechnical Evaluations and Utility Testing for 2022 Pavement Management Program Projects.
 
Topographic Surveys
City Council awarded four proposals for topographic surveys to Hakanson Anderson on August 8, 2021. Staff has since received the surveys and performed a basic review which confirmed the requested surveys are complete and thorough. The surveys will be used to create an existing ground surface and locate features once project design begins.
 
Geotechnical Reports
City Council awarded three proposals for geotechnical reports to Haugo Geotechnical Services on August 8, 2021. The reports were for each reconstruction project and will be used to help determine the required pavement section, if any soil corrections will be anticipated, and if utility work will require special backfill or groundwater considerations. Staff has received all three reports and has done an initial review, which determined the reports were complete and met the requirements of the proposals.
 
Sewer Cleaning and Televising
City Council awarded two proposals to Hydro-Klean, LLC for cleaning and televising sanitary sewer and storm sewer on August 24, 2021. The proposals were for Improvement Projects 22-01 and 22-04, both of which are urban section roadways with sanitary and storm sewer. Autumn Heights is a rural section, and the existing street crossing culverts are anticipated to be replaced, therefore cleaning and televising would not be beneficial. To date Staff has received approximately 95 percent of the televising reports, which are being reviewed. Based upon the initial review some minor storm sewer pipe repairs will be required on Sunwood Drive. More review of the sanitary sewer is required to determine if repairs will be necessary.
 
Watermain Leak Testing
City Council awarded two proposals to Water Conservation Services, Inc. for watermain leak testing on August 24, 2021. The proposals were for Improvement Projects 22-01 and 22-04, both of which have city water throughout. The leak testing has been complete and no leaks were discovered.
 
Anticipated Project Scopes
IP 22-01 Sunwood Drive and Waco Street Reconstruction: This project proposes reconstruction of Sunwood Drive between Trunk Highway 47 and Waco Street and Waco Street between Sunwood Drive and 150^th Avenue. The streets are 45 feet wide urban section, and total 0.48 miles in length. Sunwood Drive has an Average Daily Traffic (ADT) count of 1,800, Waco Street has an ADT of 600. Staff is anticipating using the full-depth reclamation process for both street segments, however, Staff recommends reducing the width of Waco Street to 32 feet wide, to match Waco Street to the south of Sunwood Drive. Waco Street to the north of 150^th Avenue is a 24-foot wide rural section. To conform to MSA Standards, reducing the width of the street would require no parking on one side of the road. Storm sewer repairs are anticipated, however, sanitary sewer and watermain repairs are not anticipated. Estimated project costs are $405,000 ($368,000 MSA Funds, and $37,000 Storm Water Funds).
 
IP 22-02 Autumn Heights Street Reconstructions: This project proposes reconstruction of the streets within the Autumn Heights subdivision, which is generally located in the northwest corner of the city, spanning both sides of Armstrong Boulevard. The streets are 24 feet wide rural section, and total 1.61 miles in length. Staff performed 5 traffic counts, focusing on streets leading into and out of the neighborhood. Counts ranged from 71 to 160 ADT, which is typical for residential streets. Staff is anticipating using the full-depth reclamation process where possible. Staff has further review of the geotechnical report to perform, but is anticipating a portion of the project to require soil corrections to remove undesirable materials from below the street. No sewer and water exist in the project area and is not proposed. The existing drainage ditches along the roadway are performing well to Staff’s knowledge, this will be explored further during project design. Staff is proposing to replace the existing street crossing culverts with the project. Estimated project costs are $984,000  ($895,000 Pavement Management Funds, and $89,000 Storm Water Funds).
 
IP 22-03 2022 MSA Pavement Overlay Improvements: This project proposes mill and overlay of Riverdale Drive between the Armstrong Boulevard Interchange and Llama Street. Staff will determine the exact project end point during design, but anticipates the project limits stopping east of Llama Street to accommodate the Riverdale Drive extension to Bowers Street. Riverdale Drive is 0.24 miles in length, urban section with bituminous curb. Traffic counts were taken west of the interchange and found an ADT of 450. Staff is not proposing any repairs to watermain or sanitary sewer with this project, minor storm sewer structure repairs, typically re-grouting catch basins, is proposed. Estimated project costs are $69,000 ($63,000 MSA Funds, and $6,000 Storm Water Funds).
 
IP 22-04 2022 Neighborhood Pavement Overlay Improvements: This project proposes mill and overlay of four subdivisions within the City; Sunfish Lake Business Park 2^nd, Sunflower Ridge, The Ponds of Ramsey, and Tiger Meadows. The project totals 2.69 miles in length, all proposed areas are urban sections with varying street widths. Staff is not proposing any repairs to watermain or sanitary sewer with this project, minor storm sewer structure repairs, typically re-grouting catch basins, is proposed. Additionally, any pedestrian ramps will be brought up to current ADA compliance. Estimated project costs are $624,000 ($567,000 Pavement Management Funds, and $57,000 Storm Water Funds).
 
IP 22-06 Wood Pond Hills 2^nd – 5^th Street Reconstructions: This project proposes reconstruction of the streets within the Wood Pond Hills 2^nd, 3^rd, 4^th, and 5^th subdivisions, which are generally located southwest of Nowthen Boulevard and Sunwood Drive. The streets are 32 feet wide urban section, and total 0.88 miles in length. Staff performed four traffic counts, and found ADT ranging from 175 to 300. Staff is anticipating using the full-depth reclamation process and performing spot concrete curb and gutter repairs for the majority of the project. Staff is aware of more severe curb and gutter damage within the Junkite Street cul-de-sac, south of 145^th Court, and will determine the best treatment during the design process. Minor storm sewer repairs are proposed, typically re-grouting catch basins. Watermain repairs and sanitary sewer repairs are not currently proposed. Further review of the televising reports is required before final determination if sanitary sewer repairs are required. Estimated project costs are $550,000 ($500,000 Pavement Management Funds, and $50,000 Storm Water Funds). Any sanitary sewer repairs would be proposed to be paid with Sewer Utility Funds, and are not included in the current cost estimate.
 
Project Timelines
City Staff is proposing to prepare plans and specifications for 2022 pavement management program projects in-house, as part of their normal duties. The following are the proposed general project timelines:
 
October 26, 2021         City Council Authorization to prepare plans and specifications
Nov. 2021 - Jan. 2022  Staff prepares plans and specifications
Jan. - Feb, 2022           City Council approve plans, authorize bidding
Feb. - Mar. 2022           Bid opening, City Council award contracts
May - June, 2022         Begin Construction
September 2022          Finish Construction
 
Staff proposes to bid projects separately, but to bid and award projects as close together as practical, which generally allows for a better bidding environment for the City.  

Staff anticipates this case will take approximately 10 minutes to present and respond to questions.

Observations:
Estimates are CIP level and will be updated during the design process.
 
Alternatives:
Alternative #1: Motion to recommend City Council authorization to prepare plans and specifications for 2022 Pavement Management Program projects.
 
Alternative #2: Motion of other.

Funding for these projects is proposed to be a combination of Pavement Management Funds, Municipal State Aid Funds, and Storm Water Funds as identified in this case and within the proposed 2022 – 2031 Capital Improvement Program.

Staff recommends alternative #1.
