water exist in the project area, and utility extensions to the area are not proposed. The existing drainage is through
<br />swales adjacent to the roadway and street crossing culverts. Two culverts which carry flow from Anoka County
<br />Ditch 66 to the Rum River are proposed to be replaced as part of this project. Additionally, Staff is aware of
<br />Northern Natural Gas mainline crossings in three locations across the project. Staff is anticipating much of the
<br />project will require subsoil corrections. Public Works Staff in the past has patched areas of the road with clay
<br />coming up to the surface of the pavement, and several spots of vertical displacement can be found in the
<br />pavement. The project proposes to replace existing street crossing culverts, otherwise drainage issues within the
<br />project area are not known, and the swales are performing well. This will be explored further during project
<br />design. Estimated project costs are $2,283,456, with $2,204,160 Pavement Management Funds and $79,296
<br />Storm Water Funds as the proposed funding sources.
<br />IP 23-06 2023 MSA Pavement Overlay Improvements Project Scope
<br />This project proposes pavement mill and overlay improvements to Riverdale Drive between Ramsey Boulevard
<br />and Feldspar Street. Staff will determine the project end points during design, and will coordinate the westerly
<br />project limit, which is generally anticipated to be near the pedestrian crosswalk east of the Holiday gas station
<br />driveway, with the future Ramsey Boulevard Interchange design plans. Riverdale Drive is 0.61 miles in length, 40
<br />feet wide urban section measured to the face of curb. The average daily traffic (ADT) vehicle counts between
<br />Ramsey Boulevard and Garnet Street is 3,450 ADT, and between Garnet Street and Feldspar Street it is 1,100
<br />ADT as of 2019. Staff is not proposing any repairs to watermain or sanitary sewer with this project, minor storm
<br />sewer structure repairs typically re -grouting catch basins is proposed. Additionally, all pedestrian curb ramps will
<br />be improved to comply with current Americans with Disabilities Act (ADA) compliance. Estimated project
<br />costs are $209,688, with $190,625 Municipal State Aid Funds and $19,063 Storm Water Funds as the proposed
<br />funding sources.
<br />IP 23-07 2023 Neighborhood Pavement Overlay Improvements Project Scope
<br />This project proposes pavement mill and overlay improvements within five residential subdivisions within the
<br />City; Alpine Meadows and Highlands at River Park 1st, 2nd, 3rd, and 4th Additions. The project totals 1.83 miles in
<br />length. The streets in all proposed project areas are urban sections (curb and gutter with storm sewer) with varying
<br />street widths. Staff is not proposing any repairs to waterman or sanitary sewer with this project. Minor storm
<br />sewer structure repairs, typically re -grouting catch basins, is proposed. Additionally, all pedestrian curb ramps
<br />will be improved to comply with current ADA standards. Estimated project costs are $517,000, with $470,000
<br />Pavement Management Funds and $47,000 Storm Water Funds as the proposed funding sources.
<br />IP 23-10 Whispering Pines Estates Plat 3 Street Reconstructions
<br />This project proposes reconstruction of the streets within the Whispering Pines Estates Plat 3 residential
<br />subdivision, which is generally located west of Armstrong Boulevard between 157th Lane and 158th Lane. The
<br />streets are 24 feet wide rural sections, totaling 1.72 miles in length. Traffic counts have not been taken, but Staff
<br />anticipates typical neighborhood traffic volumes. No municipal sewer or water exists in the project area, and
<br />utility extensions are not proposed. The existing drainage is through swales adjacent to the roadway and street
<br />crossing culverts. The neighborhood includes Whispering Pines North Park, which is a vacant low area servicing
<br />as a ponding area for the subdivision. No improvements to the Park have been proposed. Proposed CIP costs
<br />reflect a full -depth reclamation process. Staff believes this subdivision would be a good candidate for the
<br />reclamation rehabilitation process used on the streets west of Armstrong Boulevard as part of the Autumn Heights
<br />Street Reconstruction project performed in the fall of 2022. This process would require good sub -soils which will
<br />be determined from the geotechnical report, due December 30, 2022. In general, the existing drainage ditches
<br />along the roadways appear to be performing well but drainage improvements will be explored further during
<br />project design and review of the topographic survey. Staff is proposing to replace the existing street crossing
<br />culverts with the project. As part of the project, Staff will be exploring the feasibility of increasing the size of the
<br />66-foot diameter cul-de-sac on the south end of Eland Street. Estimated project costs are $1,065,680, with
<br />$968,800 Pavement Management Funds and $96,880 Storm Water Funds as the proposed funding sources.
<br />Project Timelines
<br />Staff is proposing to prepare plans and specifications for these 2023 Pavement Management Program projects
<br />in-house, as part of their normal duties. The following are the proposed general project timelines:
