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 2 which indicates these streets require complete reconstruction. Pictures of the streets are located in Appendix A in the attached Feasibility Report. Proposed Improvements Proposed improvements include removing the existing bituminous pavement and aggregate base along with 2-feet of unsuitable subgrade material. Two -feet of select granular borrow (sand) will then be placed over geotextile fabric, with drain tile added at low points. Four -inches of imported aggregate base will then be placed, followed by 3''/-inches of new bituminous pavement. This results in a 7-ton pavement design, which is the City standard for residential streets. Existing ditches will require minor re -grading due to the proposed soil corrections, but driveway culverts are not anticipated to be affected by this project. Drain tile will be added at the bottom of the subgrade correction areas to drain any trapped water into the ditches. No other storm sewer improvements are proposed with this project. Estimated Costs The engineer's opinion of probable costs for completing the proposed improvements outlined in this report is $239,464.57. 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 $194,880.41, special assessments to benefiting properties in the amount of $31,359.20, and storm sewer funds in the amount of $13,224.96. A total of 8 benefiting parcels have been identified as eligible for special assessments. Staff recommends assessing 25-percent of eligible project costs equally across the 8 benefiting properties using the "per lot" assessment method as allowed by the City's adopted Special Assessments Policy. Eligible project costs include everything except subgrade correction costs. This results in a proposed preliminary assessment rate of $3,919.90 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 6:30 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 3 of the 8 identified benefiting properties attended. None of the property owners objected to the project and all agreed the pavement was in poor condition and needed to be replaced. Their primary concern was on how access to properties would be maintained during construction, especially during the 2-foot subgrade correction work. Staff informed the property owners that this work should only take a few days to complete, and that Staff proposes to require the contractor to restore the road at the end of each work day to allow full access to driveways overnight, though this would not allow access to driveways during the work day. One way around this could be to limit subgrade correction work to one side of the road at a time, and to fill part of the ditch in on the other side of the road to provide temporary access at all times, but this would likely substantially increase project costs as the entire right -of way would need to be re -graded and restored.
