Understanding of Need / Scope of Work TASK 2.4: Budgetary Analysis Bucknam will review all city provided maintenance projects that have been completed since the last major PMP update (i.e. June 2019) as well as a listing of "scheduled" for M&R over the next seven years. These records will be assessed and entered into StreetSaver. Our staff will generate an updated work history report for City review and compliance. We will assist the City in developing the most cost-effective preventative maintenance, rehabilitation and R&R strategies possible. This will be accomplished by meeting with the City to discuss and strategize maintenance activities that are currently being used by the City. Based on the City's current AC & PCC applications and other M&R practices used we will conduct an historical and prospective analysis on the conditional and financial impact these current practices have on the pavement network. Based on our fiscal and deterioration analysis, we will present our results and recommendations to City staff. This analysis will become an essential building block for the 2022-2029 fiscal year maintenance programs. We will establish/update a M&R "decision tree" that will be used to generate pavement recommendations that match current 2021 practices. This will be accomplished by assessing/updating the unique and individual deterioration curves within StreetSaver based on functional class (i.e. arterial, collector, local), ride quality, traffic volumes and age. Our staff will review the Santa Ana's deterioration curves that have been developed based on historical pavement condition, inspection, surface type, StreetSaver deterioration, and road class. The curves will be modified based on 2021 pavement conditions. The strategies that are typically reviewed are rehabilitation and reconstruction (R&R), localized maintenance, slurry seals, and various overlay types, the expected improvement in pavement condition, the life -cycle extension that would result and the unit costs for maintenance. All maintenance practices/unit costs will be integrated into StreetSaver and will be derived from the most recent construction bids for pavement rehabilitation. We will account for inflation rates when long-term revenues projections are made. Our staff will also update the City's residential maintenance zone approach. We will focus on projecting budgets and maintenance recommendations for all streets within maintenance zones; this will allow us to proactively schedule maintenance efforts throughout the multi -year CIP as well as achieve the desired level of PCI across the City. Our Project Manager and Principal will work closely with City in defining repair and rehabilitation strategies during each fiscal year (i.e. 2022-2029). Once the repair/rehabilitation strategies have been defined, the identification of a seven year Forecasted Maintenance schedule will be generated. The recommended budget scenarios will be identified on the basis of several criteria: • Assessment and review of the City's Pavement CIP; • Present pavement conditions; Desired levels of service and available resources; • Cost benefit of individual strategies (e.g. maintain 80 PCI, reach a PCI of 85 in 7-years); • Recommendations budget strategies and unit costs City of Santa Ana 3-6 Pavement Management Program Update
