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

36. 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

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.
