Most of the land for the neighbourhood was annexed by the city between 1910 and 1919, with the remaining southern piece annexed between 1960 and 1969. A 1913 map shows that the present-day Avalon area overlaps three registered subdivisions of the day: Avalon in the northwest, Pacific Addition in the east and railway stock yards in the south. Home construction, however, did not begin in earnest until after World War II. The layout of the streets reflects the changing urban planning philosophies of the day as the land was developed. The north part of the neighbourhood follows a traditional grid pattern. By the 1950s, the design of residential neighbourhoods used a modern system of curving residential streets, feeding into collector roads that connected to arterial roads. Thus, the southern part of the neighbourhood follows this design practice.
