2 Berkeley Streets: An Introduction Our streets today

3 PRESENTATION OUTLINE 1. Berkeley Streets Existing Transportation Network 2. Pavement Condition Index (PCI) 3. City Auditor s Report & Recommendations 4. Pavement Management Program & Streets Maintenance Program 5. PW Commission 5-Year Street Plan 6. Watershed Management Plan Berkeley Streets: Pavement Management Program 3

4 CONDITIONS, PROGRAMS & PLANS Existing Transportation Network 216 centerline miles maintained: Arterials (major roadways) 21 miles Collectors (connecting residential to arterials) 37 miles Residential (neighborhood streets) 158 miles Berkeley Streets: Pavement Management Program 4

5 TECHNICAL TERMS & TOOLS Pavement Condition Index (PCI) Numerical indicator of ride quality of sections of paved streets on scale of 100 (excellent) to 0 (failed), based on smoothness of the pavement s surface, which also indicates its structural integrity. StreetSaver Software Online pavement management software developed by MTC and used by all 9 Bay Area counties to track PCI. Includes option to build scenarios based on funding level strategies. Federally approved and required for certain funding sources. Berkeley Streets: Pavement Management Program 5

6 CONDITIONS, PROGRAMS & PLANS Pavement Conditions & Ratings This graphic (from Audit Report page 15) shows the breakdown for Berkeley as of April PCI Category Total Linear Miles by PCI Category Linear Miles Percentage of Total % Very Good-Excellent (100-80) Good (79-70) % Fair (69-60) % At Risk (59-50) % Poor (49-25) % Failed (24-0) % TOTAL % Source: Audit staff analysis of Berkeley s PCI data in StreetSaver Poor (PCI=49-25) Miles 24.94% Failed (PCI=24-0) Miles 12.18% At Risk (PCI=59-50) Miles 13.29% Very Good - Excellent (PCI=100-80) Miles 25.01% Good (PCI=79-70) Miles 12.87% Fair (PCI=69-60) Miles 11.70% Berkeley Streets: Pavement Management Program 6
