Snohomish County Public Works is dedicated to maintaining and improving pavement to preserve the county’s roadway network condition and investment. To ensure this, every summer Public Works preserves and rehabilitates designated county roads through its annual Paving Program and Chip Seal Program.

Crews post signs prior to beginning work in an area to provide advance notification to the affected communities. Resurfacing is very weather dependent – rain and cool temperatures will delay work and impact the planned schedule for completion. However, every effort is made to complete the proposed list of roads during the given year.

The selection of roads to be paved and chip sealed are part of a yearly process in which the county rates a portion of the roadway network to develop the most cost-effective, multi-year plan for preserving and maintaining county roads. All major roads are rated every two years. All residential roads are rated every four years.
