If, in accordance with the provisions of this chapter, changes are made in district boundaries or other subject matter portrayed on the zoning map, such changes shall be made on the Official Zoning Map promptly after the amendment has been approved by the Village Board, together with an entry on the minutes of such Board meetings as follows: "On (DATE), by official action of the Village Board, the following change (changes) was (were) made in the Official Zoning Map: (brief description of nature of change), "which entry shall be signed by the Mayor and attested by the Clerk.
