rate of $1,303.70 per assessable parcel. Staff recommends ordering a special benefit consultation report for this project to verify the proposed assessment amount will not exceed the benefit to the properties. If the report concludes the benefit to the 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. Ten (10) soil borings were completed by Northern Technologies (NTI) to assist with the preparation of this report. Pavement design recommendations were offered by NTI, and Staff considered and incorporated NTI's recommendations to varying degrees while preparing this report. Ground Penetrating Radar (GPR) was conducted on street segments within the project. The GPR identifies existing bituminous pavement and aggregate base thicknesses, and is used to help Staff determine the appropriate treatment. Copies of Braun Intertec's GPR results and NTI's Geotechnical Exploration Report are attached in Appendix C. This improvement project, which is listed in the City's current 10-year Capital Improvement Plan, is proposed to be funded using a combination of special assessments to benefiting properties, street reconstruction bond proceeds, and storm sewer funds. Staff has not yet discussed the proposed improvements with local property owners. However, Staff has scheduled a neighborhood information meeting for November 7, 2018 for the purpose of explaining the proposed improvements and assessments in more detail, and to gather public input on the project, including any information which should be explored in more detail during development of plans and specifications. Staff will incorporate comments and present this information to Council during the Public Hearing on November 13, 2018. This project would best be constructed as a stand-alone project and is necessary, feasible, and cost-effective from an engineering standpoint, and can be constructed as proposed herein. Notification: Upon Council approval, Staff will publish the Public Hearing Notice in the Anoka Union Herald on October 26 and November 2, 2018. Staff will also mail Public Hearing Notices to the owners of all benefiting properties. Observations/Alternatives: Observations: If these streets are not reconstructed in 2019, they would need to be added to the next 5-year SROP to allow reconstruction between 2020 and 2024 instead. However, this would reduce the amount of pavement maintenance work that can be completed in 2019 since no new streets can be added to the current 5-year SROP, which is attached for reference. This is the final year of the 2015 - 2019 Street Reconstruction and Overlay Program (SROP). Developed properties along the project corridor may have private irrigation systems. Impacts to these systems may occur during construction. Staff will notify property owners in writing of the pending construction as far in advance of construction as possible to allow them time to move their irrigation system components out of the construction area, after which they may replace the components in their original locations. Following Council approval to order the Public Hearing, Staff will initiate survey work on site to allow this information to be collected before it snows. Alternatives: Alternative #1 — Motion to adopt Resolution #18-221 accepting the Feasibility Report and ordering a Public Hearing for November 13, 2018, for Improvement Project #19-03, Wood Pond Hills and Chestnut Ridge Street Reconstructions. Alternative #2 — Motion denying adoption of Resolution #18-221 at this time. Funding Source: The Feasibility Report was completed in-house as part of Staffs normal duties. Per the attached Feasibility Report, the engineer's opinion of probable project costs is $372,236.52. Staff proposes to fund the proposed improvements using a combination of special assessments to benefiting properties, street reconstruction bond funds, and stormwater utility funds, as needed.
