The Council shall divide the City into four (4) Wards which shall be as nearly equal in population as is practicable not later then January 15, 1967. In the month of January of any calendar year, the Council shall adjust the boundaries of the four (4) wards in accordance with Ohio Revised Code Section 731.06 so that following each such adjustment the substantial equality in population of the four (4) wards shall be maintained. Each ward shall be composed of contiguous territory bounded by natural boundaries and street lines, to the end that the population of each ward will have representation equal to that of each of the other three (3) wards in the government of the City.
