Maintenance will be scheduled for a minimum of every three years but will be done more frequently in segments where there is greatest change and use rate. Trails are placed in six ROS classes. There are notable overlaps. The classes may suggest levels of use or intensity that may influence the frequency or intensity of maintenance work. Most trail work includes removing windfalls, brush growth, rock falls, and erosion gaps.
Windfalls are major problems.
They need to be removed along with trees near trails in a condition likely to fall. Trees across a trail will have a section removed so that the remainder of the log is farther than 4 feet from the center of the trail. Cuts are made at an angle to allow the section to roll free with minimum worker effort. The uphill cut is usually made first. Later cleanup should reduce needs for further work and stabilize trail-side soils.
