INTRODUCTION <br />The City of Santa Ana (City) Public Works Agency utilizes StreetSaver and geographical <br />information system (GIS) to develop the Pavement Management Program (PMP) to provide an <br />accurate inventory of the past, current and projected pavement condition of all public roadways <br />and alleys and to implement the roadway and alley maintenance and rehabilitation (M&R) <br />program to maximize the return from available existing funding for street and alley pavement. <br />The City currently manages 27.4 centerline miles of alleys for a total of approximately 2.5 million <br />square feet (SF) of paved surfaces. To assist planning maintenance needs, the alleys are also <br />arranged into over 350 sections and classified by surface types — Asphalt Concrete (AC) or <br />Portland Cement Concrete (PCC). Pavement condition inspections for the alleys database are <br />performed every four to six years and the alley network inspection was performed in 2018. <br />Table 1, Figures 1 and 2 show the summary and backlog for the entire alley database. <br />Table 1: Alley Database Summary (Based on 2018 Inspection) <br />Pavement <br />Quality <br />PCI <br />PCC <br />AC <br />Backlog <br />Centerline <br />(mile) <br />Area (SF) <br />Centerline <br />(mile) <br />Area (SF) <br />Very Good <br />86-100 <br />4.9 <br />426,568 <br />0.3 <br />23,980 <br />$ - <br />Good <br />75-85 <br />2.4 <br />230,145 <br />0.3 <br />28,372 <br />$ 590,000 <br />Fair <br />60-74 <br />3.0 <br />297,880 <br />0.8 <br />73,636 <br />$ 1,300,000 <br />Poor <br />41-59 <br />0.6 <br />64,560 <br />1.3 <br />118,592 <br />$ 1,100,000 <br />Very Poor <br />0-40 <br />0.0 <br />0 <br />13.7 <br />1,199,949 <br />$ 22,700,000 <br />TOTAL <br />10.9 <br />1,019,153 <br />16.5 <br />1,444,529 <br />$ 25,690,000 <br />FIGURE 1 ALLEY DATABASE: PCI & CENTERLINE (mile) <br />■ Very Poor 0-40 Poor 41-59 Fair 60-74 Good 75-85 ■ Very Good 86-100 <br />City of Santa Ana 2020 PMP (Alleys) 1916-6 <br />
