History grade
What drives Montesano’s History grade
On its age, its old homes and the National Register, Montesano is more historic than 57% of U.S. towns, #47 of 285 in Washington. Its share of homes from before 1940 holds the grade up; its age pulls it down.
B
HistoryA character grade: shown, never part of Montesano’s overall grade.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Montesano’s 2.4 sits above most of its state (66% of Washington towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share is a Census survey estimate (±6.7 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1870 falls in the same era, so the grade doesn’t depend on which one is used.

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.
According to Edwin Van Syckle, a portion of the present-day town of Montesano was first platted in 1870 by Samuel Henry Williams, who purchased land in what was known as Wedcalf Prairie, named after the early settler William Medcalf. At about the same time, surveyor Charles Newton Byles bought a farm from Walter King on the present-day site of Montesano on April 9, 1870, and later platted three blocks on the west side of Main Street. The town of Montesano was born, but it was not incorporated until November 26, 1883, by the Washington Territorial Legislature.
