What drives Royal City’s History grade

On its age, its old homes and the National Register, Royal City is among the newest of U.S. towns. Its National Register listings hold the grade up; its age pulls it down.

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 Royal City’s 0.0 sits below most of its state (27% of Washington towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would still be D−. The pre-1940 share (±2.6 points) is firm at this size. Two sources give 1956.

The story

How Royal City came to be

From Wikipedia’s history of Royal City.

Read it all →

Royal City was founded in 1956 and officially incorporated on February 14, 1962. The townsite was previously named Royal Flats, and the entire area Royal Slope, thus the name Royal City. During the 1960s, there was a Titan I ICBM silo located near the town. The Royal Slope was named Washington state's 15th designated wine growing region (AVA - American Viticultural Area) on September 2, 2020.

Today, this small farming community is most known for producing a wide variety of crops, thanks to a long growing season. Apples, cherries, peaches, timothy and alfalfa hay, melons, potatoes, onions, wine grapes, pears, mint and corn are grown in this area. The Royal Slope area is a popular place for birders, hunters, and golfers as well.
