For those of us with weak terminology skills, what does it mean to change the trail from Class 2 to Class 1?
Class 1 is a more primitive trail. For full details see Appendix B of the scoping letter.
Forest Service Trails Management Handbook (FSH 2309.18) provides direction for
trail classification. Trail Classes are an inventory convention used to identify
applicable Design Parameters and to determine relative cost (and trail attributes) to
meet the National Quality Standards for trails. There are a total of 5 Trail Classes,
however only Trail Class 1 and 2 apply to this project. Dry River, Isolation and
Rocky Branch Trails are all currently classified as Class 2. This project proposes
reclassifying sections of these trails to Class 1.
Trail Class 1 is categorized as minimal or undeveloped. Trails in this class may
require some route finding, and obstacles such as logs or rocks, and wet crossings
may be present. Any constructed features on Class 1 trails are minimal and of native
materials. Generally Class 1 trails do not include bridges across streams; and signs
are the minimum required.
Trail Class 2 is categorized as simple or minor development. Trails in this class have
a discernible trail tread, which can be narrow and rough in areas. Obstacles are
occasionally present. Vegetation may encroach into the trail to a lesser extent than on
Class 1 trails. Structures are of limited size, scale and number, and primitive foot
crossings and fords are common. Signs are the minimum required for basic direction
and are generally few in number.
Class 1 trails generally receive minimal maintenance and are distinguished from
Class 2 trails by narrower tread width (14 inches vs. 18 inches) and clearing limits
(minimal vs. 2 feet from centerline and 10 feet overhead), and by more obstacles on
the trail and missing trail segments. Bridge stream crossings on Class 1 trails are
uncommon. Please see Appendix B for more information on Trail Classes.
