Definition: Scenic Road

Section 15C. Upon recommendation or request of the planning board, conservation commission or historical commission of any city or town, such city or town may designate any road in said city or town, other than a numbered route or state highway as a scenic road; provided, however, that a numbered route may be designated by a city or town as a scenic road if its entire length is contained within the boundaries of said city or town, and no part of said route is owned or maintained by the commonwealth.

After a road has been designated as a scenic road any repair, maintenance, reconstruction, or paving work done with respect thereto shall not involve or include the cutting or removal of trees, or the tearing down or destruction of stone walls, or portions thereof, except with the prior written consent of the planning board, or if there is no planning board, the selectmen of a town, or the city council of a city, after a public hearing duly advertised twice in a newspaper of general circulation in the area, as to time, date, place and purpose, the last publication to occur at least seven days prior to such hearing; provided, however, that when a public hearing must be held under the provisions of this section and under section three of chapter eighty-seven prior to the cutting or removal of a tree, such hearings shall be consolidated into a single public hearing before the tree warden and the planning board, or if there is no planning board, the selectmen of a town, or the city council of a city, and notice of such consolidated public hearing shall be given by the tree warden or his deputy as provided in said section three of chapter eighty-seven. Any city or town making said scenic road designation may make an ordinance or by-law establishing that a violation of this paragraph shall be punished by a fine not to exceed three hundred dollars.
