A.
When an annual tax or local assessment is levied upon a parcel of land, and two or more persons are or become the owners thereof, or it is situated in more than one ward, an apportionment of such tax or assessment shall not be made, unless a map thereof, showing a subdivision of the same into lots, with the numbers of the lots and their dimensions and all proposed streets, lanes and alleys, shall be filed with the Assessor of the City, and with the Clerk of Monroe County, and such apportionment shall be made upon all the lots shown on said map so filed.
B.
The Assessor of the City, when certifying to the Council the manner of apportionment of a tax or assessment, shall state in such certificate whether or not such a map has been so filed.
C.
The Assessor of the City is hereby requested, in making such apportionment, to place only a nominal portion thereof upon the proposed streets, unless for good reasons it seems just to them to do otherwise.
