the attached Feasibility Report. The City evaluates and rates the condition of pavement sections on all City streets on an annual basis using the Pavement Surface Evaluation and Rating (PASER) system. In the summer of 2018, the pavement section of the above referenced street segments were rated with a PASER rating of 3 which indicates these streets require complete reconstruction. Pictures of the existing streets are located in Appendix A in the attached Feasibility Report. Proposed Improvements The existing bituminous pavement section will be reconstructed using the Full Depth Reclamation (FDR) process, which involves reclaiming the existing bituminous pavement section, along with a portion of the underlying aggregate base. The reclaim material generated by this process is then spread over the reshaped and compacted existing aggregate base between the curb and gutter. Excess reclaim material is then removed and hauled off site to allow 3'/2-inches of new bituminous pavement to be placed over the remaining compacted reclaim material. This results in a 7-ton pavement design, which is the City standard for residential streets. Existing ditches will likely require some re -grading. Driveway culverts are generally not anticipated to be affected by this project. Additional storm sewer is anticipated to be added to improve storm runoff water quality prior to flowing into Trott Brook. Drainage easements may also be needed in one or more locations. Estimated Costs The engineer's opinion of probable costs for completing the proposed improvements outlined in this report is $502,555.46. Estimated costs include 5-percent contingency costs plus 23-percent indirect costs for administrative, engineering, finance and legal costs. A summary of the engineer's opinion of probably costs is included in Appendix Bin the attached Feasibility Report. Funding Program This project is proposed to be funded using a combination of street reconstruction bond proceeds in the amount of $371,754.41, special assessments to benefiting properties in the amount of $92,784.30, and storm sewer funds in the amount of $38,016.75. A total of 21 benefiting parcels have been identified as eligible for special assessments. Staff recommends applying 25-percent of all eligible project costs equally across the 21 assessable properties using the "per lot" assessment method as allowed by the City's adopted Special Assessments Policy. Eligible project costs include all costs except those related to subgrade corrections. This results in a proposed preliminary assessment rate of $4,418.30 per assessable parcel. Staff recommends ordering a special benefit consultation report for this project to verify the proposed assessment amount will not exceed benefit to the properties. If the report concludes the benefit to assessed properties is less than the proposed preliminary assessment rate, Staff will then propose to lower the assessment rate accordingly during the Assessment Hearing, which is scheduled for October 8, 2019. If the report verifies the assessment rate as proposed is justified, Staff will propose to adopt the final assessment roll using the rate as preliminarily proposed. This improvement project is listed in the City's current 10-year Capital Improvement Plan. Public Comment Staff conducted a public information meeting for this project at 5:00 PM on Thursday, November 8, 2018. The purpose of the meeting was to present the proposed improvements, estimated costs, funding program, and preliminary project schedule to benefiting property owners, and to receive public input on the project. Property owners from 2 of the 21 identified benefiting properties attended. In summary, the property owners agreed that the pavement was in poor condition and needed to be repaired but they thought the estimated project cost was too high and questioned why the City couldn't maintain the roads in a
