Off-road ditches - ~75
Roadside ditches - ~3,000
$2 billion current backlog
Reported structural flooding
Systems not meeting design criteria
$300M Annual Investment Need
FY12-16 Plan – $280M Investment
5. Street and traffic (n) PROGRAM 5 Existing Infrastructure (miles)

6. Rebuild Houston (Street & Drainage)Looking Forward 6
8. Objective of New Candidate projects (Street and drainage) Reduce the risk of flooding
Improve mobility and road safety
Address areas of greatest need first
Focus will be on needs and conditions across the City
8
9. How to get there - ReBuild Houston Funding of Pub. Infrastructures
Integration of CIP (Street & Drainage)
Planning and Programming
MTFP vs CMP
Pavement Condition Assessment
Study of COH current Pavement Design Practices
Sustainability Design (Green Roadway)
12. NEED STANDARDS
15. Pavement Condition Survey/Rating
22. REPLACEMENT - PCR
34. Pavement Design Practices (Study) Review COH design/Const practices for improvement of pavement performance issues
Key Recommendations
45’ Exp Joint Spacing and 15’ Sawed Cont Joints
1” Asphalt Bond Breaker (To Be Further Eval)
Min Design Traffic Loading (e.g., Annual ESAL for Thoroughfare 200,000, 30 yr design life, 11” conc)
Better QA/QC Testing/Inspection during Const. (e.g., pH test for lime %, depth of lime stab., edge of pavement/blockout, …)
35. Challenges Drainage/Traffic
Constituent Concerns
ROW Issues
Agency Approval
Private Project Coord.
Private Utility Coord.
