City of Santa Ana, CA Page 5 2024 Citywide Pavement Management Plan – OCTA Submittal Final Report – May 27, 2024 FINDINGS AND RECOMMENDATIONS Through our assessment of historical maintenance performed within the City and through our discussions with City staff the conditional data found across the network clearly shows that the City has applied strong, preventative maintenance strategies over the past decade. Pavement management involves frequent preventative maintenance; as pavement deteriorates through heavy traffic impacts, weathering and time, preventative maintenances (such as slurry seal, stop gap, etc.) have limited benefits. Our study has shown that key overlay projects will be needed over the next seven years to maintain the network’s high level of condition. Currently, the City’s two major streets networks (Arterial & Local) hold very high weighted PCI values; it is our recommendation that a proactive, common sense overlay program and a continued slurry seal program be scheduled over the next several fiscal years. This will ensure that the citywide weighted PCI will sustain itself and allow for routine slurry seal maintenance to continue. We have found and recommend the following detailed items which should be reviewed and considered for a proactive approach to the future management of the PMP: ARTERIAL / COLLECTOR (MPAH) FINDINGS AND RECOMMENDATIONS The actual workload requirements identified indicate that the Arterial (MPAH) street network is currently in “fair” condition. To maintain this condition, it is critical that preventive maintenance and overlay activities are funded at the levels identified on page 9 to maintain a “fair” network weighted average PCI value. Our MPAH findings for conditional data and recommendations for revenue expenditures are shown below: • The MPAH network has a weighted PCI of 72.7 • The MPAH network consists of 129.3 miles and 33,615,007 SF of pavement; • Currently, 12% of the MPAH network (15.8 miles) qualify for slurry seal/stop gap maintenance; 22% of the MPAH network (28.4 miles) qualify for rehabilitation/reconstruction maintenance; • MPAH maintenance projects should focus on the increasing the current PCI above a weighted average of 80 by FY 2031; • Develop a proactive fiscal and planned approach to identify MPAH overlay projects based on the deterioration modeling within StreetSaver; o Appropriate the MPAH CIP revenues at an average of $12,420,700/yr level for the seven- year term to generate the beneficial results identified on page 9; and o The Santa Ana “Increase PCI” budget (page 9) will increase the MPAH weighted PCI of 72.7 to 75.0 after seven years, additionally, the citywide deferred backlog increases from a level of $285.2 million to $440.3 million after seven years; and • Perform pavement inspections on the MPAH network every two years to continue the City’s
