Ladera is a census-designated place (CDP) in southern San Mateo County, California, adjacent to Portola Valley. Primarily a residential community, it comprises approximately 520 homes, governed by the Ladera Community Association. The ZIP Code is 94028 and the community is inside area code 650. The population was 1,557 at the 2020 census.


Ladera is located at the bottom of the eastern slope of the Peninsula Range of the Santa Cruz Mountains. It is bordered on the west by the Jasper Ridge Biological Preserve operated by Stanford University, on the east by Alpine Road, and on the north by Webb Ranch.

According to the United States Census Bureau, the CDP covers an area of 0.4 square miles (1.1 km²), all of it land.


The community of Ladera occupies land that was originally settled by the Ramaytush Ohlones peoples prior to the settlement of California by the Spanish. Ladera is located on the Rancho Corte de Madera Mexican land grant.

The land was used for grazing and timber through 1927 when it was joined to the Ormondale Ranch, owned by the Macdonough family. The Macdonoughs raised cattle and sheep, and bred racehorses; their most famous horse, Ormonde, raced primarily in England and never lost a race. In the 1930s, the majority of the Ormondale Ranch land was developed and incorporated into Portola Valley.

In 1944, the Peninsula Housing Association (PHA) was formed with the goal of purchasing a tract land and developing a housing cooperative. Several prominent members of the Stanford and Palo Alto communities joined to develop the fledgling PHA co-op. It began subscribing members in 1945 and its 150 members purchased the remaining 260 acres (1.1 km2) of the former Ormondale ranch for $155,000 on July 31, 1946. The co-op selected noted landscape architect Garrett Eckbo to lay out the design for the new community.

The members chose the name Ladera (over alternatives Lark Hills and New Rochdale) to reflect the Spanish history of the land — ladera is Spanish for hillside. Streets are Spanish phrases or botanical names. Early members of the cooperative included author Wallace Stegner and Klystron tube inventor Sigurd Varian of Varian Associates. (Varian had grown up in Halcyon, another intentional community in southern California.)

Due to financial difficulties caused in part by refusal to place restrictive covenants on the title deeds, the PHA failed after only a few houses had been constructed. The land was sold to Hare, Brewer, and Kelley, who completed the development.
