Agenda - Public Works Committee - 10/16/2018

Home

The subgrade soils in this area of the City are known to include areas of clay, which may require subgrade corrections. Staff therefore ordered soil borings while developing the Feasibility Report. The results of the borings were only recently submitted so Staff was still evaluating the project impacts at the time this case was prepared. More information will be presented to the Committee during the meeting. Preliminary project costs were previously estimated at $240,000. Based on the results of the soil borings analysis, this estimate could change. Staff will address this in more detail at the meeting. Staff proposes to fund the proposed improvements using a combination of special assessments to benefiting properties, street reconstruction bond funds, and stormwater utility funds. Improvement Project #19-02, Brookview Estates Street Reconstructions Attached are Figures showing the general location of the Brookview Estates development in the northeast corner of the City, as well as the overall scope of the proposed improvements. The City of Ramsey's current 10-year Capital Improvement Plan (CIP) covers calendar years 2018 to 2027. The plan identifies all public streets proposed to be reconstructed or to receive overlays in 2019 as part of the City's long-term Street Maintenance Program. Page 223 from the CIP is attached which shows the streets in Brookview Estates were proposed to receive overlays in 2019. In the spring of 2018 Staff re-evaluated the pavement condition of these streets and found the pavement has degraded past the point where an overlay should be applied, and that a total reconstruct is now required. Staff therefore recommends that these streets be reconstructed in 2019 to allow bonds to be used to pay for the improvements per the City's 2015 - 2019 Street Reconstruction and Overlay Program (SROP). The streets proposed for reconstruction in 2019 within the Brookview Estates residential development include about 2662 linear feet (0.50 miles) of streets including: • 173rd Avenue — Germanium Street to east CDS • Germanium Street — 170th Lane to north CDS Attached is a street summary sheet including year of original construction, historical maintenance operations, PASER rating(s), and existing pavement section data based on the Ground Penetrating Radar analysis completed by Braun Intertec in 2017. In general, these streets are 39 years old and have reached the end of their useful life requiring complete reconstruction. The subgrade soils in this area of the City are known to include areas of clay, which may require subgrade corrections. Staff therefore ordered soil borings while developing the Feasibility Report. The results of the borings were only recently submitted so Staff was still evaluating the project impacts at the time this case was prepared. More information will be presented to the Committee during the meeting. Preliminary project costs were previously estimated at $407,000.
