Evaluation and Rating (PASER) manual. PASER uses a visual inspection to evaluate pavement surface conditions with a 0 — 10 scale (0 equals a gravel street, 10 equals a brand-new pavement). The PASER manual recommends a number based on surface defects (raveling, flushing, polishing), surface deformation (rutting, shoving, settling, frost heave), cracks (transverse, reflection, slippage, longitudinal, block, alligator), and patches and potholes. Based on experience with the City's street system, and years of using PASER, Staff is able to associate a PASER value with a recommended pavement maintenance or rehabilitation treatment. Two things to note are that PASER is a subjective evaluation, and the PASER value alone is not sufficient to determine a pavement treatment. In general, Staff uses the following guidelines to assign pavement treatments: PASER > 7 Crack Seal is a cost-effective pavement maintenance treatment • Below a 7, crack sealing becomes not as cost-effective due to the amount of material needed. PASER > 6 Pavement Mill and Overlay is a cost-effective treatment • In general, reflective cracking will migrate through 1-inch of bituminous per year. Within 2 years, reflective cracking is expected to show. Streets valued below 6 typically exhibit block cracking and/or some alligator cracking which would reflect to the surface of new overlay pavement. The cracks allow water into the base, resulting in a shortened life of the overlay. PASER < 4 Pavement Reconstruction of some form is necessary. • Any street segment with a PASER value of 4 or less is ideally included in the current Capital Improvement Program for reconstruction. City-wide the goal is to have an average PASER value of 7. This would represent the majority of streets being above the desirable condition. Based on the 2024 PASER evaluation, the overall city street average value was 6.59. MSA collector streets had an average of 7.70 and neighborhood streets had an average of 6.34. What this means is the City's collector streets are generally in good condition. However, there is catch up work to be done on the neighborhood streets. Proposed 2025 — 2034 Capital Improvement Program: Staff is proposing the following modifications to the CIP for existing projects: • Move part of the Sunwood Drive and Rhinestone Street Concrete Repairs from 2029 to 2025 o This includes Sunwood Drive Pedestrian Crossing Repairs (MSA Funded) • Remove Beaudry's 2nd subdivision from the 2025 Neighborhood Overlays Improvement ry g y p O 2024 PASER values fell to 5. Further Staff review found an overlay no longer cost-effective • Move Bunker Lake Boulevard (Jackal Street to Armstrong Boulevard) Reconstruction from 2032 to 2027 o This segment of road is to be funded using approximately 50-percent MSA funds and 50-percent development fees. During the Oppidan development, TIF 18 District was created. Any TIF 18 funds must be spent by 2027 and may be used to offset MSA funds for this project. • Move Deerwood Street Reconstruction from 2032 to 2027. O 2024 PASER Values for this subdivision fell to mostly 3 with some 4's. Staff has observed pavement reveling and alligator cracking, and believes significant pavement patching would be required to maintain this pavement until the previously proposed 2032 reconstruction. Staff identified 5 subdivisions for 2034 street reconstruction totaling 5.55 miles. Streets selected for reconstruction had PASER values of 4 within the subdivision. Staff feels these subdivisions will likely require patching in the interim years before the street reconstruction project and will continue to monitor. An additional 2 subdivisions and 4 MSA street segments totaling 3.00 miles were identified for pavement overlay in 2034.
