Guardrail Vegetation Management

To control noxious weeds and invasive species that may cause a safety concern for motorists or pedestrians, compete with desirable vegetation on the right of way, or are detrimental to the environment, the Bureau implements an annual herbicide spraying program. Herbicide application allows for the effective and low cost control of noxious weeds during the growing season and improves the appearance of County maintained rights-of-way.
The Bureau advises property managers, homeowners and community associations to avoid installing plantings in the public right-of-way as this area may be subject to excavation, roadside mowing, brush cutting or herbicide spraying.
Application is done by a two person crew certified by the Maryland Department of Agriculture. Work is performed during the growing season, usually April through October. Areas of application include county maintained guardrails and select concrete structures such as curbs, traffic islands and monolithic sidewalks. Herbicide is applied judiciously in locations where weed whacking, mowing or manual removal have their limitations. Specialized spray equipment achieves cost efficient application with minimal use of herbicide. Desirable vegetation is avoided and efforts are made to minimize application in environmentally sensitive areas. No pesticides or fertilizers are used for roadside vegetation management.
Please click on this link for the list of road segments included in the herbicide program. Select segments of guardrail are maintained by private communities or individuals and are not treated. If you wish to have a guardrail segment removed from our spray list, or if a guardrail segment has been overlooked for treatment, please call Road Operations at (410) 222-7045 from 8:00 a.m. to 4:30 p.m., Monday through Friday.
