The Department of Transportation has the following powers:
The Department may widen, relocate, change, or alter the grade or location thereof, or alter the location or configuration of the lines or systems above or below ground. No agreement for use of Department right-of-way under this sub-subdivision shall abrogate the Department's ownership and control of the right-of-way. The Department may adopt policies and rules necessary to implement this sub-subdivision.
All changes or alterations authorized by this subdivision are subject to G.S.136-54 to G.S.136-63, to the extent that those sections are applicable.
Nothing in this Chapter authorizes the Department of Transportation to allow or pay anything to any county, township, city, or town, or to any board of commissioners or governing body thereof, for any existing road or part of any road heretofore constructed by the county, township, city, or town, unless a contract has already been entered into with the Department of Transportation.
In consultation with university system and community college horticulture programs and the North Carolina Forestry Association, the Department shall use seeds and plants the U.S. Department of Agriculture has classified as native to a state or county in the Southeastern United States, including cultivars and varieties thereof that were not bred to have reduced reproductive structures, with a strong preference for plants the U.S. Department of Agriculture has classified as native to North Carolina, in the highway right-of-way in the promotion of erosion control, landscaping, and general protection of the highways, except that the Department may use (i) nonnative grasses, plants, and seeds for the purpose of soil and slope stabilization for erosion control and (ii) nonnative turf grasses. For purposes of this subdivision, the Southeastern United States means the states of Alabama, Georgia, North Carolina, South Carolina, Tennessee, Virginia, and the following counties in Florida: Bay, Calhoun, Escambia, Gulf, Holmes, Jackson, Okaloosa, Santa Rosa, Walton, and Washington. The Department shall also have the power to acquire by gift or otherwise land for and to construct, operate, and maintain roadside parks, picnic areas, picnic tables, scenic overlooks, and other appropriate turnouts for the safety and convenience of highway users; and to cooperate with municipal or county authorities, federal agencies, civic bodies, and individuals in the furtherance of those objectives. None of the roadside parks, picnic areas, picnic tables, scenic overlooks, or other turnouts, or any part of the highway right-of-way shall be used for commercial purposes except for any of the following:
Every other use or attempted use of any of these areas for commercial purposes constitutes a Class 1 misdemeanor, and each day's use constitutes a separate offense.
This subdivision applies only to sections of roadway where the minimum sight distance as defined in the published "Policy on Street and Driveway Access to North Carolina Highways" is not available for a proposed driveway.
The Department shall adopt rules and regulations setting forth the criteria and procedures for the designation of scenic highways and scenic byways under this subdivision.
Those portions of highways designated as scenic by the Department prior to July 1, 1993, are considered to be designated as scenic highways and scenic byways under this subdivision, but the Department shall remove from this designation portions of those highway sections that meet the criteria set forth in this subdivision, if requested.
