EXHIBIT 2 3.0 Pavement Network 3.2 PAVEMENT CONDITION INDEX The City utilizes PCI output from StreetSaver as the rating mechanism to describe the City street pavement condition. This numerical index ranges from PCI of "0" for a failed and/or badly deteriorated pavement with virtually no remaining life to PCI of "100" for a pavement in perfect condition. A street section with proper engineering design and construction begins its life cycle as anew or recently rehabilitated street with a PCI of"100". As the condition of the street surface begins to deteriorate, the PCI decrease reflects the surface deterioration based on the signs of distress noted during the field surveys (refer to Section 2.0 Methodology and Appendix D: Quality Assurance/Quality Control Plan). Although the surface treatment recommendation for each street section utilizes the PCI value as the basis, the PCI values shall be used for planning purposes only and are not intended to replace sound engineering judgment. An engineering review of the pavement condition shall take place prior to any actual construction work at a particular street section because the review may indicate that a particular pavement section needs attention earlier than the other street sections in its localized area. In general for planning and budgeting purposes, the correlation among the PCI, pavement quality and signs of distresses are summarized in Table 3-2: Table 3-2: Pavement Condition Index and Treatment Type Pavement Quality PCI Pavement Description The pavement is new or almost new with very little or no roughness Very Good 86-100 and surface distress (except utility patches if any), including minimal hairline cracks and/or weathering. The pavement structure is sound and no oxidation occurs. The pavement has minor roughness and little to slight surface Good 75-85 distresses (except utility patches if any), including slight cracking, slight to moderate weathering. The pavement structure is sound and no oxidation occurs. The pavement may have noticeable roughness and slight to Fair 60-74 moderate distresses are surfacing, including severe weathering, non-load-related cracking, depressions, and material loss. The pavement structure is becoming deficient minimal base failure). The pavement has noticeable roughness (significant surface distortion) and moderate to severe surface distresses, including Poor 41-59 severe weathering, load-related cracking (such as alligator cracking), depressions, material loss. The pavement structure is deficient (up to one-third base failure). The pavement has severe surface distresses, including large Very Poor 0-40 quantities of distortion and major and unsafe cracking (alligator cracking). The pavement structure is inadequate (over one-third failure). City of Santa Ana 2026 Pavement Management Program 3-3-4
