The backbone of PMG's turnkey PMP is the PAVER Pavement Management System (PMS) which provides specific tools such as pavement modeling, maintenance decision trees and budget/target driven scenarios maximizing the return on investment from available maintenance and rehabilitation funds, generating a prioritized plan, and identifying specific areas in need of maintenance and rehabilitation. • Verify and setup any new pavement network inventory • Provide an HD video of each pavement section • Determine total samples to inspect per section • Identify all distress types, severity levels and quantities within through ASTM D6433-20 • Calculate the Pavement Condition Index (PCI) for each pavement section • Assign all pavement management data to GIS • Create GIS current condition map • Provide an HTML based condition map with geo located streaming HD video • Provide a complete inventory and condition listing of each pavement section • Provide a final report of findings • Provide continued support services 2022 ROADWAY NETWORK SUMMARY • 151 centerline miles • 248 lane miles (lane = 12 feet wide) • 15,704,016 square feet • 1,412 management sections • Average network PCI is 72 • Average network condition category of GOOD INTRODUCTION PMG was contracted by The City of Sebastian to provide pavement management services for their 151- centerline mile (248 lane mile) roadway network. Through these services a field inventory setup of any new roads, an inventory review and inspections were performed on all 1,412 management sections within the network. All inventory items were added or updated within their PMS database and a PCI was calculated for each section. HD videos were taken at each section location (from beginning to end of section). This provides for a virtual, high -definition account of the roadway network, and provides value in a variety of ways such as condition review and network level decision making from the office. This report provides a thorough definition of the inspection process performed as well as the condition results of our project. 2022 PAVEMENT MANAGEMENT FINAL PROJECT REPORT CONDITION ASSESSMENT PROCESS PMG adheres to the ASTM D6433-20 standard for assessing the condition of asphalt and concrete surfaces. Our skilled inspection team reviews high -definition video of each pavement section in conjunction with our proprietary artificial intelligence (Al) model to identify and document the distress types, severity levels, and quantities that are occurring. The data goes into the PAVERTM Pavement Management System (PMS) for Pavement Condition Index (PCI) calculation, resulting in a PCI score for each management section within the network(s). PAVEMENT DISTRESS DEFINITION 20 possible distress types can occur within asphalt -based surfaces and 19 possible distress types that can occur within a concrete surface. The U.S. Army Corps of Engineers publishes the Asphalt Distress Manual and the Concrete Distress Manual. These manuals describe each distress type, the criteria to determine each severity level (low, medium, high), and how to measure each. The asphalt and concrete distress types are highlighted below in Figure 1. 01— Alligator Cracking 06—Depression 11—Patch/Utility Cut 16—Shoving 02—Bleeding 07—Edge Cracking 12—Polished Aggregate 17— Slippage Cracking 03 — Block Cracking 04 — Bumps and Sags 05 - Corrugation 21— Blow Up/Buckling 22 — Corner Break 23 — Divided Slab 24 — Durability Cracking 25 - Faulting 08 — Joint Reflection 09 — Lane/Shoulder Drop 10 — L&T Cracking 26 — Joint Seal Damage 27 — Lane/Shoulder Drop 28 — Linear Cracking 29 — Large Patch/Utility Cut 30 —Small Patch 13 — Pothole 14 — Railroad Crossing 15 — Rutting 31— Polished Aggregate 32 — Popouts 33 — Pumping 34 — Punchout 35 — Railroad Crossing Figure 1.

Based upon the distresses identified within each representative sample location inspected, a PCI number is assigned to each pavement section. This number is on a scale of 0 —100 with 0 being the worst and 100 being the best. The City of Sebastian roadway network is approximately 248 lane miles (151 centerline miles) in size. Through the ASTM D6433-20 PCI study, PMG has determined the roadway network has an average PCI of 72 and is classified as being in GOOD condition. PMG would again like to thank you for the opportunity to provide Sebastian with this PCI study and our pavement management services. Our goal is to provide the highest level of services and support, providing our clients with the data, tools, and expertise necessary to be successful in their goals of pavement management. Should you require any additional information or support regarding this PCI study or the PAVERTM PMS, please do not hesitate to ask.

(PMG). Recommendation: Staff Recommends Approval of the Final Project Report Prepared by Pavement Management Group, Inc. Background: In January of 2022 Council approved a "piggybacking" contract with Pavement Management Group (PMG) for pavement management services. The contract required an assessment of our City roads to determine the average pavement index rating. This is routinely assessed on a three to five year basis, and was last completed in 2018/2019. Between January and November 2022 PMG drove all City owned roads documenting their condition. In this report they have documented the condition of each individual City road as well as compiled the information to determine the City has an average 72 point rating on the Pavement Condition Index, or PCI score. Therefore, on average, our City roads fall within the "Good" condition category. The analysis in 2018/2019 found an average score of 75, showing our PCI has only decreased 3 points. This shows that our efforts of reconstruction and repaving as well as pavement preservation have been working to greatly reduce the rate at which our PCI index has changed. We are requesting Council formally approve this Pavement Management Group, Inc. Final Project Report. With this approval staff will move forward with finalization of the City's paving and preservation plan through fiscal year 2028.
