EXHIBIT 2 City of Santa Ana, CA Page 17 2026 Citywide Pavement Management Plan - OCTA Submittal Final Report-March 16, 2026 Additionally, Chapter 3 requires numerous data/deliverables from local agencies for OC Measure M2 eligibility. All general PCI budgetary report submittals will follow the Chapter 3 guidelines. In conjunction with the outlined items within the CPMPG Section 2 we have summarized our QA/QC procedures below: a. Descriptions of condition survey - Our staff follows the required Condition Survey Protocols (CPMPG, Chapter 2); our staff assesses each pavement section for the minimum distresses outlined within Chapter 2, page 2-1. Additionally, based on the pavement conditions found, we collect all Micro PAVE R/StreetSaver Army Corps of Engineers(ACOE)distresses, if found within the sample sections;for example, if slippage cracking, potholes, etc. are found our survey technicians record the proper information. b. How data was collected - Our surveys follow the OCTA accepted walking requirements. All sections that our staff surveys are performed through the walking method, approximately 10%of all sections surveyed were complemented with windshield surveys based on unique conditions found. Our staff physically measures the width of every section as well as measure for any square footage adjustment that need to be added or taken away from a sections "true area" (i.e. cul-de- sac, bus pads, street width variances, etc.). Samples taken always include a minimum of 2,500 SF coverage unless specific section limits prohibit this. Arterial section samples utilize a 3,500 SF sample size due to the larger section area (this is within the ASTM D6433 sample size calculation. Field crews typically include one individual for residential pavement sections while Arterial (MPAH) routes utilize a two-person crew for safety,traffic control and increases quality control. c. Accuracy required for data collection -We use a statistical sampling approach for measuring the quality of our field technician's work. In this manner, 10 percent of the original surveys are re- surveyed by a different survey crew than the original, supervised by a field supervisor, and the results are compared to the original surveys. Our QC process involves checking the field crews' work in a "blind study" fashion. Quality control checks are performed at the end of each survey week. This ensures that all field personnel are properly collecting section samples, distress types and distress severities for all street segments. When QA/QC issues are found, our staff documents the issues within Micro PAVE R's/StreetSaver's user interface. If distress types found are not within the 97% accuracy our QA/QC is expanded beyond our minimum 10% resurvey to 20% of the original survey d. Random and Systematic Re-Inspections—As described above our staff re-inspects,as a minimum, 10% of the original survey (OCTA only requires 5%). Per the agency's requests, our staff will submit PCI reports to the agency as project status reports for their review. Agencies will typically review specific pavement sections for PCI accuracy based on recent overlay or slurry seal maintenance;this serves as an initial accuracy check on our surveys(outside Bucknam QC efforts). Additionally, our staff performs "ride-a-long" surveys with local agency staff to build consensus on how our Micro PAVE R/StreetSaver ACOE surveys are performed, recorded and reported on. Random re-inspections will include a representative selection across the following categories: • Functional classed (i.e. MPAH, locals); • Surface types (e.g.AC or PCC);
