  1. Highway Maintenance and Preservation Needs Scope and Objectives Mark Fleming, JLARC Staff

  2. Study Mandated by 2013-15 Transportation Appropriation Bill (ESHB 5024) • Focus on highway maintenance and preservation needs Part One: Overview Part Two: Evaluation How are needs identified and documented? Are procedures consistent with industry and other practices? • Provides funding for expert engineering or cost estimating consultants Highway Maintenance & Preservation Needs

  3. Washington State Highways Are a Complex System • Over 20,000 lane miles of pavement • More than 3,400 bridges and structures • 1,100 traffic signal systems • 46 safety rest areas • 10 mountain passes kept open year-round • Other features include: • Weigh stations • Guardrails • Drainage ditches • Stormwater facilities Highway Maintenance & Preservation Needs

  4. Maintenance: Routine Activities Performed by WSDOT Crews Throughout the Year Example: patching potholes Maintenance $407 Million Preservation$699 Million 2013-15 Appropriations for Maintenance & Preservation Highway Maintenance & Preservation Needs

  5. Preservation: Replacing Highway Assets at End of Service Life Example: replacing pavement Maintenance $407 Million Maintenance $407 Million • 80% used for: • pavement replacement • bridge repair Preservation$699 Million Preservation$699 Million 2013-15 Appropriations for Maintenance & Preservation Timely replacement or major repair prevents higher cost of reconstruction Highway Maintenance & Preservation Needs

  6. Part One Will Address the Following Questions: • What methods and systems does WSDOT use to develop estimates of highway maintenance and preservation needs and costs? • Is each stage in the estimating process fully documented? Highway Maintenance & Preservation Needs

  7. Part Two Will Address the Following Questions: • Are the methods and systems WSDOT uses consistent with industry practices and other appropriate standards? • Are practices in place to minimize life-cycle preservation and maintenance costs? • How does WSDOT quantify risks to its need and cost estimates? • What steps are in place to ensure that requests are not unduly impacted by outside pressures? Highway Maintenance & Preservation Needs

  8. Next Steps and Contacts Part One Report January 2014 Part Two ReportDecember 2014 Mark Fleming, Project Lead mark.fleming@leg.wa.gov 360-786-5181 Tracey Elmore, Research Analyst tracey.elmore@leg.wa.gov 360-786-5178 Valerie Whitener, Project Supervisor valerie.whitener@leg.wa.gov 360-786-5191 www.jlarc.leg.wa.gov
