BACKGROUND:
After receiving several complaints of unsafe conditions and traffic hazards, the Public Works Department Transportation Engineering Division staff conducted an engineering analysis of the segment of Marsh Creek Road between Byron Highway/State Route 4 and Bixler Road. The purpose of the analysis was to determine whether that segment of roadway is able to support commercial vehicles with a gross weight of more than 14,000 pounds. Staff prepared the “Marsh Creek Road (Road No. 8943) 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, based on accepted engineering standards, the above-described segment of Marsh Creek Road cannot support commercial vehicles with a gross weight of more than 14,000 pounds on the unpaved portions of the roadway right of way. 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 the above-described segment of Marsh Creek Road without creating a traffic hazard for other vehicles, bicyclists, pedestrians, and persons that are simultaneously traveling on that segment of roadway.
In order to prohibit at all times commercial vehicles with a gross weight of more than 14,000 pounds from using the above-described segment of Marsh Creek Road, the Public Works Department recommends that the Board of Supervisors adopt the ordinance attached hereto as Attachment B.
CONSEQUENCE OF NEGATIVE ACTION:
Commercial vehicles with a gross weight of more than 14,000 pounds will continue to use the above-described segment of Marsh Creek Road, which cannot support those vehicles.
CHILDREN'S IMPACT STATEMENT:
Not applicable.
CLERK'S ADDENDUM
CLOSED the hearing; and ADOPTED Ordinance No. 2013-02 to prohibit commercial vehicles with a gross weight of more than 14,000 pounds at all times on Marsh Creek Road between Byron Highway/State Route 4 and Bixler Road, Discovery Bay area.
