Once again, residents living on unpaved county roads will have a chance to participate in a cost-share program to control dust from passing vehicles.

Letters were recently sent out to residents who participated in the program over the past three years to see if they want to participate again. Newcomers seeking information on the program can call the county road department at 758-5790 or visit online at http://flathead.mt.gov/roads_bridges. Deadline to sign up is March 16.

The minimum section accepted is half a mile. Cost last year was $1.12 per lineal foot and was split 50/50 between the county and residents along the road. Payments by property owners must be made in advance and are due by May 31.

Last year, magnesium chloride was applied to 42 miles of roads, up from 29 miles in 2010 and 15 miles in 2009. The county has budgeted $100,000 for its share of the program. Last year, it budgeted $121,000 for its share of the program.
