Section 0400-02-09-.11 - ROADS(1) Service Roads. Vehicular access lanes shall be installed and maintained within Archaeological Areas only where essential for patrol, fire control, or other management or research activities and in accordance with the Master Plan. Such lanes shall be closed to all except service and emergency vehicles. They shall provide a single track and clearing shall not extend more than seven feet on each side of the center of the lane. Existing roads no longer necessary for management purposes shall be treated as intrusions per 0400-2-9 - .07.(2) Public Access Roads. (a) Public access roads will be installed and maintained only when needed to provide for visitor utilization of the area. Installation of these roads will be in accordance with rules 0400-2-9-.22. These roads will be constructed subject to the following criteria:(b) Road development in all Archaeological Areas shall be limited to the minimum necessary to provide access for the maintenance and/or public use of the area. Roads shall be designed with extreme care and located with a concern for the archaeological resources.(c) Roads in Archaeological Areas shall be constructed for design speed not to exceed twenty-five miles per hour. Excessive cuts and fills shall be avoided. The width of the roadways shall not exceed eighteen feet. Shoulders of the roadway shall not exceed one foot in width on each side. Two additional feet of shoulder will be allowed where guard rails are needed for safety purposes. The design of all structures - bridges, tunnels, grade separation devices, retaining walls - shall be aesthetically pleasing as well as functional. Grades of up to 10% shall be used where needed for short distances. Gravel surfaced roads shall be used when practical, in keeping with the primitive character of Archaeological Areas. Asphalt or concrete surfacing may be used where heavy use will make gravel surfacing impractical or when the safety of the visitor is involved.(d) Careful attention shall be given to the impact that roads will have on archaeological features in the planning phase of Archaeological area development. Road construction will not be initiated if during this phase it is determined that the impact will be negative to the character of the area. The Division of Archaeology shall carefully weight such values as drainage, archaeological features, scenic features, noise levels, and stream flow as well as other natural characteristics of the area before determining whether a road is to be built. The exact route of the proposed road shall be inspected at the site to insure that all natural and archaeological features have been considered.Tenn. Comp. R. & Regs. 0400-02-09-.11
