STATE OF THE STREET REPORTS
Dale Mix, Design and Construction Manager, and Matt Morales, Engineer Technician, presented the 2010 State of the Street Reports to the Committee. Although the City is required to submit a report to Washington State Department of Transportation (WSDOT) every two years, staff produces an annual report to efficiently plan maintenance and rehabilitation for roadway projects.
The current (2010) data indicates 94% of Lacey’s roads are in good or excellent condition, 5% are in fair condition and less than 2% are in poor condition. The overall average Pavement Condition Index (PCI) score for the City’s entire road network is 84. The PCI is a national rating standard, which is also used by WSDOT.
Matt reported that staff evaluates each section of roadway for defects and assigns a PCI rating score from 0 to 100 based on the type, severity and extent of defects present. The City allocates $1 million annually to rehabilitate streets. The allocation is alternated every other year between residential streets and arterial streets. To determine which roads are rehabilitated, staff identifies areas where roads will need to be reconstructed during utility projects. It is anticipated that in 2011, the rating will remain close to a PCI rating of 84 for the entire roadway system.
Several topics were discussed by Committee members:
- Grant money is generally not allocated for road maintenance projects.
- The City is not authorized to collect tolls on roads – only the state legislature has that authority.
- The City could create a Transportation Benefit District that would impose up to a $20 fee on vehicle licensing to generate revenue for road projects. The City of Olympia has implemented this taxing measure, and collects approximately $400,000 annually.
- It would cost several million dollars to rehabilitate the 2.3 miles of roads rated in poor condition in order to achieve a 100% rating of roads in excellent and/or good condition. The cost outweighs the benefits.
- Encouraging carpooling could potentially reduce the wear and tear on the roads. It was noted the City participates in the regional Commute Trip Reduction Program managed by Intercity Transit. Its goal is a 35% reduction of cars on the road by 2016.
- The City continues to use alternative methods to extend the life of its roads, including thin hot-mix asphalt overlays, slurry sealing, crack sealing, cape sealing, and chip sealing.
Staff will research and report on the following items:
- The effect the 2011 Overlay and Carpenter Road projects would have on the % of the road network in the “poor” category.
- The effect of traffic speed on pavement degradation.
- Correlation between pavement condition and safety (as measured by accident frequency).
- The break point (upper bound) in cost of HMA where cement pavement becomes more cost effective.
- PCI rating for roads in Tanglewilde and Thompson Place.
- National recognition program for Best Roads in America.
