HistoryA character grade: shown, never part of Brookdale’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Brookdale’s 7.3 sits above most of its state (90% of California 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 A−. The pre-1940 share is a Census survey estimate (±13.4 points). The founding year is the first post office, not a stated founding date.

What stands out about Brookdale’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area was previously known as Clear Creek and then Brookville, and was the site of the Grover Lumber Mill by 1870. Logging and lumber was the major industry throughout the Santa Cruz Mountains at the time. James Harvey Logan, a Santa Cruz judge and creator of the loganberry, purchased the mill in 1900, created a creekside resort with cabins and camping, and established the Brookdale post office in 1902.

The Brookdale post office opened in 1902, the earliest record of the town by name (U.S. post office records).
