HistoryA character grade: shown, never part of Sunriver’s 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 Sunriver’s 0.0 sits below most of its state (18% of Oregon towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±0.3 points) is firm at this size.

What stands out about Sunriver’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Sunriver is located on the grounds of the former Camp Abbot, a World War II training facility designed to train combat engineers in a simulated combat environment. The U.S. Army camp opened in 1942, but by June 1944 the camp was abandoned and most of the settlement was razed.
The Officers' Club was spared; it has been preserved and renovated and is now known as the "Great Hall," under management of Sunriver Resort. The name "Sunriver" was selected by developers John Gray and Donald V. McCallum. The initial condominiums were built in 1968 in conjunction with the completion of Sunriver Lodge, and in 1969 the master plan was completed and developers began selling lots.
Sunriver is among the newest of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
