What drives Lynnwood’s History grade
On its age, its old homes and the National Register, Lynnwood is more historic than 15% of U.S. towns, #199 of 285 in Washington. Its National Register listings hold the grade up; its age pulls it down.
C−
HistoryA character grade: shown, never part of Lynnwood’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 Lynnwood’s 0.5 sits near the middle of its state (57% of Washington towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to C. The pre-1940 share (±0.7 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1959 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

Prior to contact with American settlers, the Snohomish tribe of Native Americans used the area of modern-day Lynnwood for summertime activities, including hunting, fishing, berry gathering and root cultivation. The Snohomish were relocated to the Tulalip reservation, near modern-day Marysville, after the signing of the Treaty of Point Elliott in 1855, opening the area for American settlement.
