Trucks rumbling across Sonoma County?s roadways ? moving rock for construction projects and trash to the dumps ? may be forced to pay a tonnage tax because the weight of their cargo is damaging to pavement.
County transportation officials are considering using provisions of their Aggregate Resources Management plan to levy a tonnage fee on rock-bearing trucks in order to defray repair costs on the county?s 1,387 miles of roads.
They calculate that one double container truck, fully loaded with 25 tons of quarry rock, does road damage equivalent to that of 10,000 cars.
?These roads are being worn out in a year or less,? said Walt Keiser, a planning consultant hired by the county to study the issue.
Perhaps surprisingly, some aggregate industry leaders don?t reject the notion of a tonnage fee. But they want the tax applied to other companies that run dump trucks, water trucks, food trucks and grape trucks that also use county roads.
?It bothers me that the aggregate operators are willing to pay a small fee but you have all kinds of trucks out there bring things into the county,? said Marv Soiland, whose family owns the Stony Point quarry. ?There are other people utilizing these roads and we would like to see everyone treated fairly.?
Wendel Trappe, owner of Canyon Rock in Forestville, called the tonnage fee ?like another nail in the coffin to local industry.? He and the BoDean Company, owner of Blue Rock Quarry in Forestville, are already paying $3.5 million for road and intersection improvements in the west county.
?Garbage trucks run year-round and the rock trucks are sitting around for most of the year,? Trappe said.
Environmental activists say payment into the roadway mitigation fund is long past due.
?We support the recommendation and do not support any alternative because that would delay repairs to the roads,? said Kate Wilson, representing the Russian Riverkeeper group.
