Road Maintenance

Maintenance District Information



Pre-level work was completed in the Leavenworth, Cashmere and Chelan road districts. On Monday, Sept. 28, county road crews will be pre-leveling on upper Entiat River Road. The crew expects to move the pre-level operation to the Wenatchee District on Tuesday, where they will be the remainder of the week. Pre-level is when the crew applies a thin layer of asphalt over Preservation Program roads to fill in ruts and low spots. Crews will use a paver and traffic controls, such as one-lane, flagger-controlled traffic, will apply in the work area. A list of roads scheduled for pre-level is available online.

Vegetation Management

Chelan County’s primary objectives for roadside vegetation management are:  

  • Provide for safe travel on County roads. 
  • Preservation of roadway infrastructure with desirable vegetation and stable roadsides.
  • Compliance with legal regulations concerning control of noxious weeds.

Herbicides are a cost-effective method of maintaining vegetation, and selective use over time require, less product to manage vegetation as native grasses and low-growing plants fill in along roadsides.

Why does the County use herbicide to thin brush?

Safe travel requires maintaining sight distance at corners, curves and intersections, ensuring water flows off of pavement and providing areas for vehicles to safely pull off the road. This is accomplished with pruning, vegetation removal or herbicide thinning of deciduous vegetation.

Herbicide thinning is only used on brush and trees (apart from landscape vegetation or commercial farms after Sept. 1). Only the limbs of the plant sprayed are affected and those limbs will not leaf out the following year. It does not kill the plant. 

What herbicides are used in the residual program?

When the spray zone is near sensitive areas, such as orchards, vineyards, residences and rivers, lakes and irrigation canals, the chemicals used in these areas are soft residual products that are safe to use up to the water’s edge and near orchards, vineyards or landscaping. In non-sensitive areas, different herbicides with selective properties can be used to address vegetation control issues. 

Why control noxious weeds?

The County is required by state law to control all listed noxious weeds that occur on the right-of-way (RCW 17.10). The County is also sensitive to the needs and concerns of adjacent landowners, both for controlling the spread of noxious weeds and the need for use of herbicides to control vegetation.

All herbicides used by the County are on the State of Washington Vegetation Management Contract. The Washington State Department of Transportation has completed toxicological and risk analysis for all herbicides on the contract and summaries can be accessed on its website. These herbicides have been determined to be the least toxic to mammals, fish and invertebrates.

When does the County spray for noxious weeds?

Control of noxious weeds is performed from mid-May to mid-September. Selective herbicides are used in non-sensitive areas to promote the establishment of perennial grasses. Non-selective herbicide (Roundup®) is used in sensitive areas as it is one of just a few herbicides that is relatively safe to use near landscaping, orchards and vineyards.
