The document provides an overview of the City of Rancho Santa Margarita's pavement management program. It details the value of the city's street system assets, common funding sources for street maintenance, the city's past spending on street projects, and the benefits of implementing a pavement management program to optimize spending and maintain pavement quality over time. Key aspects of the city's current pavement management program are also summarized, including the pavement condition index system used and analysis of maintenance needs and budgets required to maintain the current average pavement quality.

1. City of Rancho Santa Margarita PAVEMENT MANAGEMENT OVERVIEW October 22, 2008

13. Pavement Management Program Steps to Implementation of a PMP: Step 1: Assessment of Existing Pavement Network Step 2: Work History Updates Step 3: Pavement Inspections Step 4: Data Input Step 5: QA/QC Step 6: Budgetary Analysis and Reporting Step 7: GIS and Mapping

17. PCI = 100 Action  Do Nothing PCI = 100 Action  Do Nothing

18. PCI = 70 Action  Surface Treatment (Slurry) PCI = 70 Action  Surface Treatment (Slurry)

19. PCI = 50 Action  Structural Improvement (Overlay) PCI = 50 Action  Overlay

20. PCI < 20 Action  Reconstruction PCI < 20 Action  Reconstruction

25. Maintenance Zones – PCI’s

29. Maintenance Strategy Assignments $6.36/SF Reconstruction 0 - 20 $1.65/SF 1.6&quot; ARHM (Arterial) 21 - 55 $1.55/SF 2.0&quot; AC Overlay Mill & Cap (Residential) 21 - 65 Minimal Level of Service (70) $0.30/SF Slurry Seal 65 - 85 Varies by Activity Preventative, Stop Gap 80-100 Unit Cost Description PCI Range All Streets

30. Maintenance zone programs create a proactive management program that generates a greater return on the revenue’s City’s invest which in turn allows for deferred overlay & reconstruction projects to be funded without major delay. Each residential street is surveyed every three years Residential/Industrial Maintenance Zone Findings

31. Arterial PCI maintains at an average of 75 over the 7yr CIP This result is produced by spending an average of $618,000 per year Arterial Capital Improvement Program MAINTAIN CURRENT ARTERIAL WEIGHTED PCI

32. CIP – Maintain Current PCI Budget

33. Citywide residential PCI maintains at an average of 77 over the 7-yr CIP This result is produced by spending an average of $580,000 per year over the next seven years This budget model addresses every residential street within a maintenance zone each year Residential Capital Improvement Program MAINTAIN CURRENT RESIDENTIAL WEIGHTED PCI

34. CIP – Maintain Current PCI Budget

35. Comparison of All Budgets Maintain Citywide Average (76.5 PCI) Program = $1.2 Million / yr Maintain PCI of 70 Program = $900,000 / yr Constrained Program = $250,000 / yr 56.1 69.8 76.3 2014-15 59.4 71.1 76.6 2013-14 62.7 72 77.1 2012-13 66 73.4 76.8 2011-12 68.9 74.1 76.4 2010-11 71.7 74.8 76.1 2009-10 73.2 74.6 75.8 2008-09 76.5 76.5 76.5 Current Constrained Program Reach PCI of 70 Program Maintain Citywide Average Program Fiscal Year

39. Types of Slurry Seal Type I: Penetrates into finer cracks and seals better. Has lower skid resistance and should not be used on grades steeper than about 5%.Does not fill in more substantial cracking. Cleaner looking. Type II: Better skid resistance and therefore safer for traffic safety. Fills in larger defects. Some of the larger aggregate will ravel and collect in the gutters for a couple of months and will be tracked into cars and houses (aggressive sweeping needed at first). Should roll with a pneumatic tire roller at just the right time to lay down some of the sharp edges.
