Excerpt from the article by Fran Gardner:
"Nearly every address in town was changed during the process known as the Great Renumbering, which was completed in 1933. Every house was given a set of black-and-white tiles with its new number. You can still find these on houses throughout the city.
The Great Renumbering was the time when the city instituted the “quadrant” system, with addresses assigned to Northwest, Northeast, Southeast or Southwest. Burnside Street and the Willamette River became the dividers.
A fifth quadrant, North, was added to take into account the bulge of land west of Northeast First Avenue, where the river meanders westward. The dividing line is Williams Avenue.
The Great Renumbering was a time when all the north-south streets became numbered avenues (except in North and a few enclaves, like Southeast Portland’s Ladd’s Addition)."
