Vacation or relocation of a legal right-of-way after March 17, 1977, shall convert a lot that was an upland lot because of the existence of such right-of-way into a waterfront lot. For purposes of determining the appropriate use and development standards applicable to developments in railroad or street rights-of-way, the railroad or street right-of-way shall be considered to be a waterfront lot unless separated from the water by another railroad or street right-of-way.
