Pursuant to Section 1773 of the California Labor Code, the general prevailing wage rates for Marin
County where the work is to be done have been determined by the Director of the California Department
of Industrial Relations. These wages are set forth in the General Prevailing Wage Rates for this project,
available at the Department of Public Works. Prevailing Wage rates are also available at the State of
California Division of Labor Statistics and Research website
The Federal minimum wage rates for this project as predetermined by the United States Secretary of
Labor are set forth in the project Special Provisions. Future effective general prevailing wage rates
which have been predetermined and are on file with the California Department of Industrial Relations
are referenced but not printed in the general prevailing wage rates.
Attention is directed the Federal minimum wage rate requirements in the project Special Provisions. If
there is a difference between the minimum wage rates predetermined by the Secretary of Labor and the
general prevailing wage rages determined by the Director of the California Department of Industrial
Relations for similar classifications of labor, the Contractor and subcontractors shall pay not less than
the higher wage rate. The Department will not accept lower State wage rates not specifically included in
the Federal minimum wage determinations. This includes “helper” (or other classifications based on
hours of experience) or any other classification not appearing in the Federal wage determinations.

available for use by the Contractor and subcontractors, the Contractor and subcontractors shall pay not
less than the Federal minimum wage rate which most closely approximates the duties of the employees
