In the event that any or all of the Official Zoning Maps become damaged, destroyed, lost or difficult to interpret because of their illegibility or nature or number of changes and additions, the County Commissioners may, by resolution, adopt new Official Zoning Map or Maps. The new Official Zoning Map or Maps may correct drafting or other errors or omissions in the prior Official Zoning Map or Maps, but no such correction shall make a substantive change in the Official Zoning Maps. The new Official Zoning Map or Maps shall be properly attested, and a notation of the date of adoption shall be entered on the map or maps. Unless the prior Official Zoning Map or Maps have been lost or totally destroyed, the prior map or maps and any significant parts thereof remaining shall be preserved, together with all available records pertaining to the adoption and amendment of the prior map or maps.
