In Seattle’s early years, 1851 to 1889, owners of property could lay out a plan for streets and give them any names they chose. But as the city grew, segments of a street would often have several different names as the street passed through these individually-laid-out plats of property.
The Great Seattle Fire of June 6, 1889 burned a large section of the downtown core but instead of destroying the city, the Fire led to a rebirth of Seattle with explosive population growth. The population jumped tenfold to about 43,000 people in Seattle as of 1890, and doubled again by the year 1900 to more than 80,000 people.

Within three years of the Fire, four hundred new subdivisions were filed with King County, mainly in or near the Seattle City Limits. Each subdivision had a layout of streets with lots for houses or commercial buildings, and property owners continued to give the streets in their plats, any name that they chose. This resulted in a tangle of street names which were often repeated in different areas of the city. Finally in 1895 City Engineer R.H. Thomson began renaming Seattle streets via City ordinances. The street-renaming project also decreed that streets would be east-west and those that were north-south would be called avenues.
