After receiving several complaints of unsafe conditions and traffic hazards, the Public Works Department Transportation Engineering Division staff, as supported by the Byron Municipal Advisory Council and County Supervisor Piepho’s Office, conducted an engineering analysis of Camino Diablo between Marsh Creek Road and Byron Highway. The purpose of the analysis was to determine whether the roadway is able to support commercial vehicles with a gross weight of more than 14,000 pounds. Staff prepared the “Camino Diablo Truck Restriction Study” (the “Engineer’s Report”) to document the results of the analysis. A copy of the Engineer’s Report is attached hereto as Attachment A and incorporated herein by reference.
As more particularly described in the Engineer’s Report, Transportation Engineering staff has determined that, based on accepted engineering standards, the above-described section of Camino Diablo cannot support commercial vehicles with a gross weight of more than 14,000 pounds. Trucks off-tracking the paved roadway surface damage the shoulders and create dangerous depressions that make it difficult for vehicles to return to the paved roadway. Truck off-tracking may also result in encroaching onto the opposite direction of travel, leading to broadside or head-on collisions. Commercial vehicles weighing more than 14,000 pounds cannot travel on Camino Diablo without creating a traffic hazard for other vehicles, bicyclists, pedestrians, and persons that are simultaneously traveling on the roadway.
In order to prohibit at all times commercial vehicles with a gross weight of more than 14,000 pounds from using Camino Diablo, the Public Works Department recommends that the Board of Supervisors adopt the ordinance attached hereto as Attachment B.
Commercial vehicles with a gross weight of more than 14,000 pounds will continue to use the above-described segment of Camino Diablo, which cannot support those vehicles.
