I. A class A trail shall be a full public right-of-way, of indefinite duration subject to public trail use restrictions. It shall not have the status of a publicly approved street, and shall not be used as a vehicular access for any new building or structure, or for the expansion, enlargement, or increased intensity of use of any existing building or structure. It may, however, be used by the owners of land abutting on such trail, or land served exclusively by such trail, to provide access for such nondevelopment uses as agriculture and forestry, or for access to any building or structure existing prior to its designation as a trail, and such owners’ access for such uses shall be exempt from applicable public trail use restrictions, subject only to reasonable time, season and manner regulations imposed by the local governing body. The municipality shall bear no responsibility for maintaining the trail for such uses by abutting owners. Such owners shall, prior to excavation, construction or disturbance of a class A trail, obtain permission from the municipal officers, in the same manner prescribed for highways in N.H. Rev. Stat. § 236:9-11.
II. A class B trail shall be a full public right-of-way of indefinite duration subject to public trail use restrictions. It shall not have the status of a publicly approved street, shall not be used as a vehicular access for any new or existing building or structure, and shall not be used by the owners of land served by or abutting on such trail in any manner inconsistent with applicable public trail use restrictions.
