Notwithstanding any other provision of this chapter, if two or more contiguous lots of record are under the same ownership as of or after November 9, 1989, and one or more of such lots has an area less than 30,000 square feet, then all such lots that are less than 30,000 square feet shall be deemed merged into adjacent lots under the same ownership and the merged lots shall be considered one lot for the purpose of this chapter. This provision shall not apply to any lots that are located within a B-1 or B-2 Zoning District or to any recorded lots which were approved and accepted by the Planning Board before November 9, 1989, pursuant to Chapter
300, Subdivision of Land. This provision shall not apply when the substandard lot of record has an area equal to or greater than the area of 50% of the lots within 200 feet of the subject lot, as confirmed by the Zoning Official through the submission of a Compilation Survey of the property prepared by a Rhode Island Registered Professional Land Surveyor, by the property owner. This Subsection
C shall be deemed to have been adopted and effective on November 9, 1989, in place and instead of the zoning amendment adopted on that day.
