4. PROPOSED IMPROVEMENTS 4.1 Bituminous Pavement Overlays 4.1.1 Pavement Condition Evaluation/Ratings City staff generally evaluates and rates the pavement conditions of all city streets on an annual basis using the Pavement Surface Evaluation and Rating (PASER) system. This requires a visual evaluation of each pavement surface throughout the City based on the type, extent and severity of each pavement distress observed. Various types of pavement distresses may exist within a pavement section including, but not limited to, alligator cracking, block cracking, longitudinal cracking, transverse cracking, rutting, raveling, shoving, potholes and patches. Once staff gathers the updated field data, it is recorded in a Microsoft Excel pavement management database. This database is used by staff to determine the most cost-effective pavement rehabilitation method for each street segment, and to schedule the annual long- term Street Maintenance Program projects. 4.1.2 Project Area Selection Staff reviewed the pavement management database to identify street segments throughout the City with PASER ratings from 3 to 5 as these are the best candidates for overlays. These segments were then evaluated as to proximity and overall scope to determine which segments could be grouped together to help reduce bid prices related to equipment mobilization, which often accounts for 5% or more of bid prices. The City's 5-year Street Reconstruction and Overlay Plan proposed to overlay several segments in 2018. These include; Woodland Green, The North Forty 2" d, The North Forty 3rd, Northfork Itasca Shores, Northfork, Northfork 2" d, Northfork 3rd, and Northfork Oaks. In total, approximately 63,449 square yards of pavement is proposed to receive overlay improvements. Exhibits A, B, C, D, E, F, and G in Appendix A show the location and scope of the proposed 2018 overlay improvements. 4.1.3 Other Considerations Driveways: Overlaying of existing residential driveway aprons may be needed to varying degrees with this project. The limits of each overlay will vary with each driveway based on the elevation of the street abutting the driveway apron, the driveway pavement condition and type, and the locations of existing driveway pavement joints. During construction, staff will evaluate the construction limits for each driveway and will work with each property owner to determine the proper overlay limits in the field. Right - of -entry may be needed from residential property owners to complete work outside City right-of-ways and easements.
