    187 Tons of material. Requires 38 round trips to Santa rosa for material, 1122 miles +- for asphalt.
    The Lee Boy modification was to the whell drivers from the laying machjing to the truck wheels.

City road crews are paving streets for the first time in several years after resurrecting once-defunct paving equipment — a welcome move in a city where street maintenance remains a top concern among residents.

What the city is getting out of using the equipment is the ability to tackle its most decrepit roads with a solution that will last for at least five years, and probably more than a decade. "Roads that have this type of repaving done can last for a long time," said Roads Supervisor Mike Ielmorini. "We pick the areas where streets have totally failed, those with too many potholes and cracks to patch, and we grind down the pavement, level it, prep it and lay down a two-inch overlay. We pick the areas where we can stay for a whole month and get as much done as we can."

Public Works Director Dan St. John pointed out that the two-inch-thick repaving the equipment enables is not the same as a complete reconstruction of the road, but is the longest-lasting remedy that can be performed before all-out reconstruction is required.

The city currently has no long-term funding mechanism to fully repair its failing roads and is looking at a possible sales tax measure in 2014 to fund the estimated $7 million per year needed to get Petaluma's roads back to a desirable condition.

The asphalt grinder that is now being used to repair roads was purchased during a time when the city had a much larger budget and wanted to begin repaving its own roads rather than outsourcing the work. But soon after buying the machine, the economic downturn hit Petaluma and caused layoffs that decimated the roads crew, making the machine essentially useless.

Instead of expanding the roads department, as had been planned before layoffs occurred, the crew was cut, leaving no one in the city who possessed the Class A drivers license needed to drive the machine from jobsite to jobsite. Ielmorini explained that current employees are not required to have a Class A license and that becoming certified would require a change to employee contracts.

In addition, another piece of equipment, the paving machine was not designed to work with the city's current dump trucks, which are required to accompany the machine during repaving. While new, compatible dump trucks may once have been planned as a later purchase, strapped city finances put an end to that idea. In total, the city logged only 12 hours of usage on the paving machine before relegating it to storage.

In November, the City Council voted to sell the barely used machine for a fraction of the $185,000 it paid for it in 2007. But when the city received no offers, despite only asking $70,000 for it, the Public Works Department decided to take a new approach. St. John challenged Ielmorini and the roads crew to see what they could do to make the equipment usable again.

"I thought that I had to find a way to use this piece of equipment," said Ielmorini. "It just can't sit. I'm a citizen of Petaluma and I want to see my tax dollars at work.

"I began calling the manufacturer, talking to different paving companies and figured out a way to retrofit the machine to fit our dump trucks," said Ielmorini. "The guys on my crew did most of the work themselves."
