A METHOD OF FIELD DESIGN APPLIED TO FOREST ROADS

An efficient system of survey and design for low-volume roads was needed for the Six Rivers National Forest to meet increased production and enviornmental demands. New road standards based on measurement of existing roads were formulated, and a system of survey and design was developed that accomplished all quality and quantity goals. The survey-design system requires a highly qualified reconnaissance engineer and geologist for road location in steep, unstable topography. A six-man crew obtains field data by using a compass and cloth tape. Seventy-five percent of the road is staked by use of tables. The remainder of the road is designed by using simple manual or shortcut computer design methods. The cost is 10 to 15 percent of the conventional P-line, L-line procedure. Work accomplished to date indicates that this field design system meets all necessary requirements for survey and design of low-volume roads. Research and development in progress will further improve this method.
