      2.   Where district boundaries are so indicated that they approximately follow the lot lines, such lot lines shall be construed to be said boundaries;

      3.   Where district boundaries are so indicated that they are approximately parallel to the centerlines or street lines of streets, or the centerlines of right-of-way lines of highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the Official Zoning Map. If no distance is given, such dimensions shall be determined by the use of the scale shown on the Official Zoning Map; and
