What drives Corvallis’ History grade
On its age, its old homes and the National Register, Corvallis is more historic than 83% of U.S. towns, #7 of 142 in Oregon. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
A−
HistoryA character grade: shown, never part of Corvallis’ overall grade.
Oregon towns list more on the Register than most of the country (a typical Oregon town has 2.9 per 10,000 residents, the U.S. 2.4), so Corvallis’ 85.7 sits above most of its state (94% of Oregon towns have fewer) while its 514 historic buildings outnumber those of 97% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share (±1.4 points) is firm at this size. Two sources give 1845.

Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
In October 1845, Pennsylvanian Joseph C. Avery arrived in Oregon. Avery took out a land claim at the mouth of Marys River, where it flows into the Willamette River, and in June 1846 took up residence there in a log cabin hastily constructed to hold what seemed a potentially lucrative claim. Avery's primitive 1846 dwelling was the first home within the boundaries of today's city limits and his land claim included the southern section of the contemporary city.
