Road Maintenance and Preservation

The Kitsap County Road Maintenance and Operation Division maintains and preserves over 900 miles of roadway in unincorporated Kitsap County.

The county is divided into three road maintenance districts—North, Central and South. Each district has experienced staff and necessary resources to make sure our roads are safe for travel. View the road district map. (Title 136 WAC

The Division also maintains structures that lie within the county Right of Way that support the roadway.  These structures include roadside shoulders, ditches and culverts, sidewalks, guardrails, bulkheads and seawalls, and bridges. (RCW 36.82.070)


Pavement Preservation Program (P3) 

The P3 program uses PMS (Pavement Management System) computer analysis, hands-on experience, and information from stakeholder groups to develop a multi-year plan identifying targeted roads and type of surface preservation treatment required. Treatments are identified by priority programming procedures and asset needs determined by roadway usage, function and performance.

Surface treatments include:

​Crack Sealing/Crack Fill
​Cape Seal
​Chip Sealing/Modified Chip Seal
​Slurry Seal
​Patching (Structural)
​Sandwich Seal
​Fog Sealing
​Maintenance Asphalt Overlay (HMA)
​Diamond Grinding/Profiling
​High - Friction Surface
​Pervious Pavement
​Micro - Surfacing

Vegetation Management Program

Vegetation management within County-maintained rights-of-way improves sight distance, prevents drainage issues, and removes trees posing a threat to driver and pedestrian safety. Road Maintenance crews  apply selective herbicides to control vegetation in the County right of way in April, May and June. This work is weather dependent. To learn when crews will be in your neighborhood, subscribe to the Road Report to receive weekly updates.

The County provides an "Owner Will Maintain" program to residents who prefer to maintain their own landscaping in the Right of Way. Follow the links below to the procedure, policy and application form for this program.

Herbicide Spraying

Herbicide spraying is part of the County’s Integrated Vegetation Management Program. All County personnel that apply herbicides are certified through the Washington State Department of Agriculture.

Kitsap County uses one or more of the following herbicide products: Cheetah Pro (Glufosinate Ammonium), Esplanade (Indaziflam), Frequency (Topramezone), Telar (Chlorsulfron), and Liberate (Lecithin).

Kitsap County will not use Glyphosate products as part of the herbicide application program. View Resolution to discontinue use of Glyphosate

Snow and Ice Removal Program

During winter snow and ice events, County crews clear County maintained roads using priorities established in the snow and ice control policy. Learn more about the program and the policy, how to read the plow map, and about de-icer.

Green Sweep Program

The Department of Public Works Road Maintenance and Stormwater Divisions coordinate a street-sweeping program called Green Sweep. The program focuses on pollutant removal and water-quality enhancement.
