If, in accordance with the provisions of this chapter and the Land Use Article of the Annotated Code of Maryland, changes are made in zoning district boundaries or other matters portrayed on the Official Zoning Map, such changes shall be made on the Official Zoning Map promptly after the amendment has been approved by the Mayor and Town Council. The amending ordinance shall provide that such changes or amendments shall not become effective until they have been duly entered upon the Official Zoning Map. No amendment to this chapter involving matters portrayed on the Official Zoning Map shall become effective until after such change and entry has been made on said map.

(2) 
The new Official Zoning Map may correct drafting or other errors or omissions in the prior Official Zoning Map and may incorporate validly enacted amendments to the Official Zoning Map, but no such correction shall itself have the effect of amending the original zoning ordinance or any subsequent amendment thereof.

Where a lot is divided by one or more zone boundary lines, each of said divisions of the lot shall be subject to the regulations of the district in which it is located.
F. 
Where physical or cultural features existing on the ground are at variance with those shown on the Official Zoning Map, or in other circumstances not covered by Subsections A through C above, the Board of Appeals shall interpret the zone boundaries.
