the existing aggregate base, removing 31/2-inches of reclaim material, then placing 31-inches of <br />new bituminous pavement on top. In general, the streets are still at the stage where with <br />maintenance, Staff feels they can be serviceable for up to 10 years, allowing the City's limited <br />funds to be spent on streets which are better candidates for overlays, or are ready for reconstruction <br />now. <br />Staff prepared a preliminary engineer's estimate for full -depth reclamation (FDR) improvements <br />for streets in the Business Park 95 industrial park, which totaled $918,332. Considering that the <br />anticipated service life for FDR improvements is up to 60 years, FDR improvements would be <br />significantly more cost-effective than mill and overlay improvements, which would cost more than <br />half what FDR improvements cost, and generally have an anticipated service life of 15 to 20 years. <br />5. CONCLUSIONS AND RECOMMENDATIONS <br />Based on the attached pavement forensics report findings, the existing pavement is not able to <br />support 2-inch mill and overlay improvements. <br />It is also important to note that it is the middle of March and in the best case scenario if other street <br />segments were evaluated and found to be able to support mill and overlay improvements in 2020, <br />the earliest a mill and overlay project using special assessments as a funding source could <br />realistically be bid would be late June or early July, meaning a contract would not be awarded until <br />the middle of August. <br />In addition, given that the City is again discussing funding options for pavement management <br />program projects, levying additional assessments might not be the best course of action at this <br />time. <br />It is therefore the recommendation of City Staff that the Amended 2020 Pavement Overlay <br />Improvements as proposed within this Feasibility Report not be completed in 2020, and that other <br />streets not be evaluated for mill and overlay improvements in 2020. <br />Feasibility Report <br />Amended 2020 Pavement Overlay Improvements <br />City of Ramsey Project No. 20-02A <br />5 <br />
