What drives Hermosa Beach’s History grade

On its age, its old homes and the National Register, Hermosa Beach is more historic than 20% of U.S. towns, #477 of 847 in California. Its share of homes from before 1940 holds the grade up; its age pulls it down.

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 Hermosa Beach’s 0.0 sits below most of its state (31% of California 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 range from D to C. The pre-1940 share (±2.7 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1907 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.

The story

How Hermosa Beach came to be

From Wikipedia’s history of Hermosa Beach.

Read it all →

Hermosa Beach was originally part of the 1784 Rancho San Pedro Spanish land grant that later became the ten-mile (16 km) ocean frontage of Rancho Sausal Redondo. In 1900, a tract of 1,500 acres (6.1 km2) was purchased for $35 per acre from A. E. Pomroy, then owner of the greater part of Rancho Sausal Redondo. Messrs. Burbank and Baker, agents, bought this land for Sherman and Clark who organized and retained the controlling interest in the Hermosa Beach Land and Water Company.
