About this file

This document provides typical brushing specifications and methods for roadside maintenance work. The specifications outline two brush clearing methods for different slope areas near roads and ditches. Method A requires cutting back brush 5 feet beyond the toe of ditches or 15 feet from road shoulders, whichever is less, extending 10 feet on fill slopes. Method B requires cutting all brush within 5 feet of road shoulders and culvert inlets, extending 5 feet on fill slopes. Both methods require cutting brush under 6 inches in diameter to provide 14 feet of overhead clearance. All woody debris must be removed from road surfaces, ditches, cut slopes, and culvert inlets and outlets. The related federal contract opportunity is solicitation number 1240BF23Q0072 for road maintenance work issued by the Forest Service within the Department of Agriculture.
