Benefits of Using Local Aggregate Resources

Transporting from shorter distances is healthier for all of us.
Decreasing the distance aggregate is shipped by an average of 15 miles across the state, saving 44 million gallons of diesel fuel, would also reduce tail pipe emissions by 835.4 tons a year of pollutants regulated by the state Air Resources board that are linked to incidents of cancer, asthma and other serious health problems. (Sources: CalTrans analysis, based on the California Air Resources Board emission factors estimates and assuming an average 55 to 60 miles per hour speed and a reduction of 282 million miles of truck travel.)

Transporting from shorter distances protects the environment and reduces traffic.
CalTrans estimates a current average hauling distance of 50 miles. If the trip length can be reduced by even 15 miles, then diesel fuel consumption can be reduced by 44 million gallons annually, and truck emissions by 835 tons per year. Traffic congestion would be reduced. And an estimated $705 million per year would be saved on material transportation costs.

Transporting from shorter distances saves money.
Most aggregates are transported by truck. The cost of trucking aggregates increases 15 cents per ton for every mile hauled. Given that even one mile of a six lane highway requires over 110,000 tons of aggregates, each mile of transport would add one-half million dollars to the base cost of the aggregates for such a project.
