The entire alley pavement network is currently in "Poor" condition with a <br />PCIaw of 45.9. Currently, only gas tax and Measure M fairshare funds are utilized to fund the <br />annual repair for alley pavement network. With an existing funding of just over $150,000 <br />annually for the alley repair program, only one or two alleys with PCI less than 10 are budgeted <br />for repair annually. Therefore, the backlog for the alley network is projected to increase <br />approximately three percent annually. Table 2 summarizes the Alley Network PCI and deferred <br />maintenance (backlog) over the next 10 years with the current abovementioned budget and <br />Table 3 summarizes each alley segment and its current estimated cost to repair. <br />Table 2: Alley Network PCI and Backlog with Current Budget <br />YEAR <br />PCI <br />Backlog <br />2020 <br />45.9 <br />$ 25,690,000 <br />2021 <br />45.0 <br />$ 26,396,082 <br />2022 <br />44.1 <br />$ 27,049,769 <br />2023 <br />43.2 <br />$ 27,715,705 <br />2024 <br />42.3 <br />$ 28,408,278 <br />2025 <br />41.5 <br />$ 29,117,307 <br />2026 <br />40.7 <br />$ 29,847,596 <br />2027 <br />39.8 <br />$ 30,598,602 <br />2028 <br />39.0 <br />$ 31,411,507 <br />2029 <br />38.3 <br />$ 32,247,231 <br />2030 <br />37.5 <br />$ 33,070,230 <br />City of Santa Ana 2020 PMP (Alleys) 1 916-7 <br />
