Here is what the Directory says about the new numbering system:
One full number is allowed for each 10 feet of frontage on each side of all
Thoroughfares, even numbers on the right and odd numbers on the left
side. The base line is a line drawn perpendicular with the foot of Woodward
Avenue, extending
easterly through
along the tracks of the Wabash Railroad: streets south of this line will be
“south.”
on
“West.”
Avenue northward
and
ordinance. North and south streets start at the base line with the numbers 100
and 101: east and west streets start at the Woodward base line with numbers
1 and 2. Each block will be a rectifying block, so that along a north and south
line from the river up, the numbers on the houses will be alike on each cross
street: the same holds true going east and west.
We only transcribed those streets that showed both new and old numbers in the Directory.
