Case Study: City of Dixon

This Tuesday, the Dixon City Council is taking it to the streets.

No, there won’t be any picketing and it won’t be held outdoors, but potential streets for inclusion in the Pavement Rehabilitation Streets List for the 2019-20 fiscal year is on the agenda for this week’s meeting.

In 2017, the state Legislature passed the Road Repair and Accountability Act, also known as Senate Bill 1 (SB1), which was subsequently signed into law by then-Gov. Jerry Brown. The legislation establishes taxes and fees to repair and maintain state highways and local streets, improve trade corridors and support public transit as well as active transportation, according to a staff report by Public Works Director Joe Leach andSenior Civil Engineer Reka Aczel.

Part of the bill includes the Road Maintenance and Rehabilitation Program and Road Maintenance and Rehabilitation Account RMRA, which allocates funds to local agencies for road repair. The League of California Cities estimates that Dixon will receive $322,000 for the current fiscal year, per the staff report.

In order to be eligible to receive these funds, the City must provide a list of road repair projects to the California Transportation Commission by May 1st,” Aczel and Leach wrote. “In addition, a final report must be provided to the State at the end of the State fiscal year.”

Staff is recommending that the city implement a five-year schedule of local streets pavement rehabilitation with slurry seal where applicable. The streets are chosen through the StreetSaver program, a computer-based pavement management system developed by the Metropolitan Transportation System which chooses roads based on their Pavement Condition Index (PCI), 100 being the streets in the best condition and 0 being streets in the worst condition.

A PCI of 80 or higher means roads are in “very good” condition, streets with a 75 PCI are in “good” condition. Roads with a 70 PCI or higher have pavement that requires mostly preventive maintenance with low levels of distress, such as minor cracks or flaking off the top layer of asphalt as a result of water infiltration, according to the report. Streets with a 69 or lower have a significant amount of degradation and require more expensive forms of rehabilitation, such as grinding or full reconstruction.

“For each $1 spent on pavement rehabilitation for roads with PCI 70 and above, it will cost $4 to $5 if rehabilitation is delayed below the PCI 69 level,” Aczel and Leach wrote.

Therefore, StreetSaver chose a list of streets with a PCI range between 70 and 85, ranking those with the lowest PCIs first, to be scheduled for rehabilitation over the course of five years.

“With an appropriation of $525,000 in FY2019/20, the City would be able to slurry seal approximately 100,000 square yards of pavement,” Aczel and Leach wrote.

After the list is selected, specifications and an estimate will be developed for advertisement in February with construction expected to start in April, Aczel and Leach wrote.

The council will receive a presentation on the proposed streets for inclusion in the list and provide direction to staff.

In other business, the council will vote on a resolution authorizing City Manager Jim Lindley to negotiate and execute an agreement with Turbo Data Systems for processing of parking and administrative citations issued by the Dixon Police Department. It would also terminate an existing agreement with Suisun City.
