§ 99.111  METHOD OF NUMBERING.
   (A)   The City Engineer, in making out the proper number of buildings on any street in the city, shall be governed by the initial or starting point, which shall be the St. Mary's and Maumee Rivers and Calhoun Street, respectively, allowing 100 numbers for each square, with an even hundred at the commencement of each square, as provided herein, and in all respects adhering to the decimal system of enumeration. Also, in all streets running in opposite direction, but not extending to the initial point, the same order of enumeration shall be observed as though such streets did actually extend to such points. And in such parts of the city as it may be impractical to accurately follow this system, the City Engineer shall arrange the numbering as nearly in accordance therewith as possible.
   (B)   One whole number shall be allowed on every 20 feet of ground wherever practicable, whether improved or vacant, provided, however, that any house or tenement with a front less than 20 feet shall receive a whole number, and that all streets running north and south shall number from the St. Mary's and Maumee Rivers or the commencement of the streets nearest thereto with odd numbers on the east side and even numbers on the west side of the street, and all streets running east and west shall be numbered east from Calhoun Street, or the terminus of the street nearest thereto, with odd numbers on the north side and even numbers on the south side, and west from Calhoun Street, or the terminus of the street nearest thereto, with odd numbers on the south side and even numbers on the north side of the streets, and in numbering the streets 100 numbers shall be allowed to each block of the usual length of blocks, so that the number of each consecutive block shall commence with consecutive hundreds and one.
