review some minor storm sewer pipe repairs will be required on Sunwood Drive. More review of the sanitary sewer
<br /> is required to determine if repairs will be necessary.
<br /> Watermain Leak Testing
<br /> City Council awarded two proposals to Water Conservation Services, Inc. for watermain leak testing on August 24,
<br /> 2021. The proposals were for Improvement Projects 22-01 and 22-04,both of which have city water throughout.
<br /> The leak testing has been complete and no leaks were discovered.
<br /> Anticipated Project Scopes
<br /> IP 22-01 Sunwood Drive and Waco Street Reconstruction: This project proposes reconstruction of Sunwood Drive
<br /> between Trunk Highway 47 and Waco Street and Waco Street between Sunwood Drive and 150th Avenue. The
<br /> streets are 45 feet wide urban section, and total 0.48 miles in length. Sunwood Drive has an Average Daily Traffic
<br /> (ADT)count of 1,800,Waco Street has an ADT of 600. Staff is anticipating using the full-depth reclamation
<br /> process for both street segments,however, Staff recommends reducing the width of Waco Street to 32 feet wide,to
<br /> match Waco Street to the south of Sunwood Drive.Waco Street to the north of 150 th Avenue is a 24-foot wide
<br /> rural section. To conform to MSA Standards,reducing the width of the street would require no parking on one side
<br /> of the road. Storm sewer repairs are anticipated,however, sanitary sewer and watermain repairs are not anticipated.
<br /> Estimated project costs are $405,000($368,000 MSA Funds, and$37,000 Storm Water Funds).
<br /> IP 22-02 Autumn Heights Street Reconstructions: This project proposes reconstruction of the streets within the
<br /> Autumn Heights subdivision,which is generally located in the northwest corner of the city, spanning both sides of
<br /> Armstrong Boulevard. The streets are 24 feet wide rural section, and total 1.61 miles in length. Staff performed 5
<br /> traffic counts, focusing on streets leading into and out of the neighborhood. Counts ranged from 71 to 160 ADT,
<br /> which is typical for residential streets. Staff is anticipating using the full-depth reclamation process where possible.
<br /> Staff has further review of the geotechnical report to perform,but is anticipating a portion of the project to require
<br /> soil corrections to remove undesirable materials from below the street.No sewer and water exist in the project area
<br /> and is not proposed. The existing drainage ditches along the roadway are performing well to Staffs knowledge,
<br /> this will be explored further during project design. Staff is proposing to replace the existing street crossing culverts
<br /> with the project. Estimated project costs are $984,000($895,000 Pavement Management Funds, and$89,000 Storm
<br /> Water Funds).
<br /> IP 22-03 2022 MSA Pavement Overlay Improvements: This project proposes mill and overlay of Riverdale Drive
<br /> between the Armstrong Boulevard Interchange and Llama Street. Staff will determine the exact project end point
<br /> during design,but anticipates the project limits stopping east of Llama Street to accommodate the Riverdale Drive
<br /> extension to Bowers Street.Riverdale Drive is 0.24 miles in length,urban section with bituminous curb. Traffic
<br /> counts were taken west of the interchange and found an ADT of 450. Staff is not proposing any repairs to
<br /> watermain or sanitary sewer with this project,minor storm sewer structure repairs,typically re-grouting catch
<br /> basins, is proposed. Estimated project costs are $69,000 ($63,000 MSA Funds, and$6,000 Storm Water Funds).
<br /> IP 22-04 2022 Neighborhood Pavement Overlay Improvements: This project proposes mill and overlay of four
<br /> subdivisions within the City; Sunfish Lake Business Park 2nd, Sunflower Ridge, The Ponds of Ramsey, and Tiger
<br /> Meadows. The project totals 2.69 miles in length, all proposed areas are urban sections with varying street widths.
<br /> Staff is not proposing any repairs to watermain or sanitary sewer with this project,minor storm sewer structure
<br /> repairs,typically re-grouting catch basins, is proposed.Additionally, any pedestrian ramps will be brought up to
<br /> current ADA compliance. Estimated project costs are $624,000 ($567,000 Pavement Management Funds, and
<br /> $57,000 Storm Water Funds).
<br /> IP 22-06 Wood Pond Hills 2nd—5th Street Reconstructions: This project proposes reconstruction of the streets
<br /> within the Wood Pond Hills 2nd, 3rd,4th, and 5th subdivisions,which are generally located southwest of Nowthen
<br /> Boulevard and Sunwood Drive. The streets are 32 feet wide urban section, and total 0.88 miles in length. Staff
<br /> performed four traffic counts, and found ADT ranging from 175 to 300. Staff is anticipating using the full-depth
<br /> reclamation process and performing spot concrete curb and gutter repairs for the majority of the project. Staff is
<br /> aware of more severe curb and gutter damage within the Junkite Street cul-de-sac, south of 145h Court, and will
<br /> determine the best treatment during the design process. Minor storm sewer repairs are proposed,typically
<br />
