HistoryA character grade: shown, never part of Maple Valley’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 Maple Valley’s 0.4 sits near the middle of its state (56% 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 D to C+. The pre-1940 share (±0.4 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1997.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Maple Valley’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area was settled in 1879 by three men who were improving a trail and brought their families in. When a name for a future community was proposed, the names Vine Maple Valley and Maple Ridge were suggested. A vote was taken by writing the names on slips of paper and placing them in a hat. Vine Maple Valley won by 2/3, but the word "Vine" was later cut by the post office because it made the name too long.
The town's early history mainly had to do with coal, lumber milling to build homes, and a railroad that ran through town. Coal was brought in from Black Diamond to the south, but the town itself also mined coal from Cedar Mountain. The mine was used as late as 1947.
