Property owners in unincorporated Whatcom County who don't want the county to spray herbicide on the road shoulder where their land is next to a county right of way must sign an agreement.
The county is scheduled to treat about 250 miles of roads this year. Lawns and yard areas may have a minimum 12-inch wide strip treated to aid drainage and minimize pavement damage, according to Whatcom County Public Works.
Property owners who don't want the treatment and agree to maintain the right of way must sign a document and receive "owner will maintain" signs from the county Maintenance and Operations office, 901 W. Smith Road.
The office can handle the request between 8 a.m. and 4 p.m. weekdays. There is no charge.
