The roadside right-of-way serves many purposes– it provides space to escape crashes, creates a sense of openness that contributes to driving ease, improves sight distances, provides space for maintenance activities, such as snow removal and storage, and provides an area that allows for proper road drainage. However, overhanging trees, brush and weeds can grow into a serious safety concern for road users, especially in and around power and telephone lines, highway medians and along the roadside.
The Washtenaw County Road Commission (WCRC) has developed a Roadside Vegetation Control Program to help keep the roadside right-of-way reasonably clear. This four-prong approach is designed to contain roadside vegetation that could obstruct motorists’ vision, obstruct the traveled portion of the roadway, create drainage problems or cause snow/ice problems if left unchecked, and includes the following actions:
WCRC uses a subcontractor to perform roadside mowing. Per their contract, they will mow along paved county roads twice and unpaved county roads once throughout the season. They do not mow along subdivision roads. The contractor is responsible for the scheduling of mowing to mow through the county most efficiently. They generally work on a township-by-township basis.

Mechanical brush mowing (Boom Mowing)
WCRC crews use a specially designed brush mower to cut back roadside brush. This equipment will focus on clearing brush that is 2” in diameter or less. This mowing will be done year-round, whenever the weather allows. Over the past decade, WCRC has not had the resources to continuously brush mow. Fortunately, with increases to road funding from the state, WCRC is finally able to restart its mechanical brush mowing program.
Specifically trained, licensed and experienced professionals selectively apply the herbicides to specific vegetation that could create a driving hazard. Spraying along county guardrails takes place each spring. Spraying along rural road right-of-way is done on a rotating basis in one quarter of the county each August. This operation is not a continuous broadcast spray – only those areas in the rural road right-of-way with encroaching vegetation will be sprayed. Herbicide spraying does not take place in subdivisions, adjacent to bodies of water, along mowed lawns or along officially designated county “Natural Beauty Roads”.Click here for a flyer describing the program.

Hand trimming is usually part of a larger road improvement project and is required to help ensure the safety of the roadway, including vertical clearance for emergency vehicles, school buses and WCRC snow plows.
