OCTA &GO <br />Local Tax Dollars at Work <br />Countywide Pavement Management Plan Guidelines <br />Countywide Assessment Standards <br />In 1998, OCTA adopted the countywide pavement condition assessment standards for treatments <br />as shown in Table 2.1. <br />Table 2.1 Pavement Condition Assessment Standards <br />Pavement <br />Quality <br />PCI <br />Thresholds <br />Funded <br />Treatment <br />Very Good <br />86-100 <br />None <br />Good <br />75-85 <br />Surface seal* <br />Fair <br />60-74 <br />Thin overlay <br />Poor <br />41-59 <br />Thick overlay <br />Very Poor <br />1 0-40 <br />Reconstruction <br />* Not eligible for CTFP competitive funding program <br />Note that Table 2.1 does NOT preclude other treatments that a local agency may choose to select <br />or use. Indeed, there have been many new pavement technologies and techniques introduced <br />since 1998 that a local agency should consider for preventive maintenance, and which may be <br />funded under the M2 Fair Share program. The treatments in Table 2.1 are intended to <br />identify the types of treatments that OCTA will fund under the competitive grant <br />program only. <br />Quality Assurance/Quality Control (QA/QC) Plan <br />A QA/QC plan must be prepared by all agencies. The purpose of the QA/QC plan is to ensure that <br />all procedures used to collect distress data comply with OCTA's guidelines and result in the <br />delivery of a quality data product. The QA/QC plan should also provide for corrective actions when <br />deficiencies are encountered. As a minimum, the following components must be included: <br />a. Description of condition survey procedures (distress types, severities) or reference to the <br />relevant documents in Chapter 3. All procedures, changes or modifications should be well <br />documented in the QA/QC plan so that future updates will be consistent. In particular, <br />unique situations are especially important and their documentation should be included. <br />b. How data will be collected (windshield, walking, automated or combination of methods). <br />C. Accuracy required for data collection. <br />d. Description of how data will be checked for accuracy by agency (e.g. re -inspections). <br />e. Schedule for when data will be submitted to local agency staff. <br />f. Experience of inspectors including past training on condition surveys or calibration <br />procedures. <br />g. Field data collection safety procedures. <br />Effective March 2024 2-5 <br />
