Said zones and overlay districts are bounded and defined on a map entitled "Newtown, Connecticut Zoning Map," dated July 1, 1969, as amended, filed with the Newtown Town Clerk and which, with all explanatory matter thereon, is hereby made a part of these regulations.
All official Zoning Maps of the Town of Newtown approved prior to the adoption of these regulations shall remain on file in the Office of the Town Clerk but shall be considered merged into the Zoning Map referred to in Section 595-1.04.100. Said maps shall have validity only to the extent that a court of competent jurisdiction finds them necessary to determine the location of a zoning boundary which it finds not determinable from the map referred to in Section 595-1.04.100 thereof.
