referenced street segments were rated with a PASER rating of 2, indicating these streets require complete reconstruction. City staff patch these streets at least once per year, particularly before winter so the streets can be plowed without further damaging the pavement. Pictures of the streets are located inAppendix A of the attached Draft Feasibility Report. On July 11, 2017, the City Council adopted Resolution #17-07-170 ordering preparation of a Feasibility Report for the reconstruction of streets in HY-10 Ramsey. These streets were originally included in the City's CIP as proposed 2015 overlay improvements. However, the overlay work was delayed when construction of the Highway 10 & Armstrong Boulevard Interchange was funded. Following completion of the Interchange, the pavement was re-evaluated and Staff determined the pavement was no longer viable for overlay improvements and instead required reconstruction. This project is now included in the current 10-year CIP as a reconstruction project. When the City Council ordered the Feasibility Report, Staff was directed to review the existing streets in HY-10 Ramsey and explore whether the streets should be reconstructed in the same locations, or whether it might make sense to realign or extend one or more of the streets to better serve existing properties and/or to connect to Bunker Lake Industrial Park. Staff therefore explored numerous alternative street alignments and/or extensions. In May of 2018, the Development Review Committee (DRC), which consists of Staff from various departments, reviewed several design alternatives and recommended reconstructing the streets in their current footprints using a pavement section similar to the existing section while replacing all existing bituminous curb on 146th Avenue and Ferret Street, and to extend the existing watermain and construct concrete curb and gutter along 147th Avenue to Ferret Street since this street will likely not be modified during redevelopment. In the end, due to the uncertainty of future development/redevelopment scenarios, Staff determined there are simply too many unknowns to justify the expense of realigning or extending street segments at this time. Attached is a figure showing the properties currently for sale in HY-10 Ramsey (to the best of Staff's knowledge) which indicates the potential for redevelopment may exist in the not too distant future. However, at this time Staff is proposing to reconstruct the streets in the same locations as they exist today with a similar pavement section as the existing section, which should provide a design life of at least 30 years. Staff has not discussed the proposed improvements with local property owners. However, staff is seeking Council approval to schedule a public information meeting for 9:00 AM on September 13, 2018 for the purpose of explaining the proposed improvements, estimated costs, and funding program, including the use of special assessments. The input gathered at this meeting will be shared with Council before they are asked to order the Public (Improvement) Hearing. Based on Council direction, the input could help shape development of plans and specifications. The Feasibility Report proposes to reconstruct the existing bituminous pavement section using the Full Depth Reclamation (FDR) process which involves reclaiming (grinding and mixing) the existing bituminous pavement with an inch or more of existing aggregate base material. A portion of this reclaimed material is proposed to be spread and compacted on top of the reshaped and compacted existing subgrade/aggregate base. Three and one-half inches of bituminous pavement is then proposed to be installed on top of a minimum of 6 inches of aggregate base (existing aggregate base/reclaim material). This pavement section would generally match the existing pavement section on these streets, and would meet the City of Ramsey's minimum standard pavement design. Though the design strength of the proposed pavement section may be slightly less than a typical industrial park pavement section, Staff believes it will provide a useful life of at least 30 years based on the life achieved by the existing pavement section. Staff also believes there is a potential for this development to redevelop within the next 10 to 20 years, resulting in the potential realignment of streets. 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:
