Each block within the city shall be designated by 100, progressively from the intersection of Columbia Avenue and Franklin Street so that, for example, the block bounded by Columbia Avenue, Franklin Street, Almira Avenue and Adams Street and facing on Columbia Avenue shall be designated as 100 and thus each block cardinally and progressively from the said main intersection shall be numbered and designated 200, 300, etc. For each ten feet of each block there shall be added one or two digits, measured cardinally from the said intersection and the lots and structures thereon shall be so numbered that odd digits shall be added to the lots and structures located on the south and west side of such streets, avenues, places or ways and even numbered digits shall be added to the lots or structures located on the north and east side of such streets as the same are progressively numbered from the said main intersection.
In any instance where a block is more than five hundred feet in length, for each twelve and one- half feet of such block there shall be added one or two digits.
