- 1. RTPA RCTF California Statewide Needs Assessment Local Transportation System 2012 Update April 10, 2013
- 2. Noise Buses Air & GHG Energy Storm water Pedestrians Bicyclists • What are pavement conditions statewide? • How much will it cost to maintain pavements? Bridges? Essential components? • What is the funding shortfall? • What is impact of different funding scenarios? Study Objectives
- 3. Local Streets Huge Part of State Network 81% of California’s pavements are owned by cities and counties!
- 4. 39% 24% 4% 15% 18% StreetSaver MicroPaver Cartegraph Other No PMS PMS Software Used 92% of total miles are included in a PMS
- 5. New Things in 2012 Assessment • Sustainable practices • Complete streets • Bridge scenarios
- 7. Average Statewide PCI 67.8 (2008) 65.8 (2012) 68 (Cities) 62 (Counties)
- 8. Statewide Average PCI = 66 This doesn’t look too bad …
- 9. So Why is 66 Critical?
- 10. Statewide Trends 2008 71- 80 (Good) 50-70 (At Risk) 0 -49 (Poor) Pavement Condition Index 2012 87% of counties have average rating of “at risk” or “poor”
- 11. Prev. Maint. Costs Increasing
- 12. AC Overlay Costs Increasing
- 15. Who Owns Bridges? National Bridge Inventory • 11,863 bridges • 6,300 are on-system • 5,584 off-system Non-NBI bridges Approx. 3,500
- 16. Bridges Are Getting Old 55% require rehabilitation or replacement
- 17. It’s Not Just Roads and Bridges • Sidewalks • Curb ramps • Curb & gutter • Storm drains • Street lights • Signs • Retaining walls
- 18. Transportation Asset Needs Pavement 72.4$ Essential Components 30.5$ Bridges 4.3$ Totals 107.2$ 10 Years ($B) Funding 13.3$ 8.7$ 3.0$ 25.1$ Shortfall (59.1)$ (21.8)$ (1.3)$ (82.1)$ Total Transportation Needs 56 cents/gal or 76 cents/day!
- 19. Pavement Funding Scenarios 1. Existing funding ($1.33 billion/year) 2. Transportation CA measure ($1B/yr) a. Bond i.e. $4.23 billion/year for first 5 years, $1.33 billion for next 5 years b. No bond i.e. $2.33 billion/year 3. Maintain current PCI at 66 4. Efficiency scenario 5. Best mgmt practices
- 20. 1. Existing Funding ($1.33 B/year) PCI drops to 53 Unfunded backlog grows to $66 B
- 21. 2a. No bond ($2.33 B/year) PCI drops to 60 Unfunded backlog grows to $50 B
- 22. 2b. Bond ($4.2B/$1.3B) $37.5 $37.5 $37.7 $38.7 $37.4 $40.0 $41.5 $42.3 $43.5 $45.5 67 67 68 68 69 68 66 65 64 63 40 45 50 55 60 65 70 75 80 $- $10 $20 $30 $40 $50 $60 $70 $80 $90 201 3 201 4 201 5 201 6 201 7 201 8 201 9 202 0 202 1 202 2 PCI Backlog($billion) Year Scenario 2b. Transportation BondPCI drops to 63 Unfunded backlog grows to $45 B
- 23. 3. Maintain PCI = 66 ($3.2 B/year) PCI stays at 66 Unfunded backlog stays at ~$39 B
- 24. 4. Efficiencies ($4.1 B/yr) PCI improves to 71 Unfunded backlog drops to $30 B
- 25. 5. BMP ($7.2 B/year) PCI improves to 84 Unfunded backlog eliminated
- 26. % Pavements in Failed Condition % Pavements in Good Condition 6.6% 56% 25% 46% 23% 68% 21% 71% 20% 78% 16% 83% 0% 100% Impacts of Different Scenarios Scenarios Annual Budget ($B) PCI in 2022 Current Conditions - 66 1. Existing Funding 1.33$ 53 2A. No bond 2.33$ 60 2B. Bond $4.23/$1.33 63 3. Maintain PCI = 66 3.23$ 66 4. Efficiency Savings 4.11$ 71 5. Best Mgmt Practices 7.23$ 84
- 31. Average Sufficiency Rating Existing budget will result in SR = 75
- 32. Percent Structurally Deficient Existing budget will result in 38% structurally deficient bridges.
- 33. Tehama County
- 35. Conclusions • Transportation system is not great and it’s not getting better – 25% of roads will be failed in 10 years – 38% of bridges will be structurally deficient • Additional funding required to hold infrastructure together • Deferring repairs will cost much more later!
- 36. Conclusions • Delays in funding will cost
