Mason County Public Works has the responsibility of engineering, construction, maintenance and administration of the Mason County Road System as defined in RCW 36.75 - 36.88. This includes all County Roads but none of the State Routes or the City of Shelton Streets.

The Public Works Department is one of the County's largest departments. The daily tasks are numerous and can vary greatly in nature. The one common point associated with all of the Public Works Department activities is the County Road System.

This website is designed to help you better understand the various functions of the Public Works Department and assist you with any related issues. We hope that you will find this helpful.

The Engineering Section is responsible for planning and developing the designs for the new road construction. This includes the management and inspection during construction, the related survey work and right of way acquisition.
