   Wherever land is hereafter subdivided within the corporate limits of the city, public streets of a minimum width of 66 feet shall be laid out on the basis of one street located every one-eighth of a mile running in one direction and one street located every one-sixteenth of a mile running in the other direction.

   In new subdivisions where the land to be subdivided is bisected, intersected or bounded by diagonal thoroughfares, railroads or Indian boundary lines, or where the boundaries of the land to be subdivided are irregular by reason of the contiguity of rivers or lakes, the arrangement and widths of streets to be laid out in such areas shall be subject to the discretion of the commissioner of transportation, responsible for maps and plats.
