Owner Maintain Program
Owner Maintain Web Banner
Properly maintained roadsides are important for the safety of motorists and active transportation users.
Pierce County's integrated roadside vegetation management program includes the use of herbicides to combat weeds and eliminate vegetation from road shoulders. In 2023, these applications will start March 27 and run through June.

Targeted noxious weed and brush control herbicide applications are also made through late November as needed. Only federal- and state-approved herbicides are used.

Crews also mow grass, cut brush, and trim trees along roadsides. 

This annual maintenance work reduces fire danger, optimizes stormwater drainage, helps control noxious weeds and non-native plants, and promotes native plant growth.
"Owner Will Maintain" agreements
Property owners who do not want the roadside vegetation adjacent to their properties sprayed with herbicides or mechanically trimmed can sign an “Owner Will Maintain” agreement with Pierce County. 

Under this agreement, the property owner agrees to maintain the vegetation. If the property owner does not meet the standards detailed in the agreement, the maintenance of the right-of-way reverts to the county. 

The property owner must display a Pierce County-provided sign indicating their participation in the program.
