History of Portola Valley

Portola Valley gets its name from Gaspar de Portolá. He was a Spanish explorer who led the first group of Europeans to explore the San Francisco Peninsula in 1769.
Native American groups, like the Ohlone, lived here first. Later, they moved to nearby missions. The written history of the area began in 1833. That's when a large piece of land was given to Domingo Peralta and Máximo Martínez. This land was called Rancho Cañada del Corte de Madera. People used it for cutting lumber and raising cattle.
In the 1880s, Andrew S. Hallidie built his home, Eagle Home Farm, in what is now Portola Valley. He was known for making wire ropes. In 1894, he built a very long cable car system, over 7,000 feet long. It went from his house to the top of Skyline. This system was removed after he passed away in 1900.
In 1886, the area was named Portola-Crespi Valley. Crespi is for Juan Crespí, a friar who was with the Portolá expedition.
The town officially became a town in 1964. Bill Lane, who was the publisher of Sunset magazine, became its first mayor.
In recent years, the town has faced challenges. In 2023, many government workers left their jobs. This happened after some residents disagreed with plans to build more homes in the town. State law requires Portola Valley to allow 253 new homes to be built.
In March 2024, Portola Valley became the first California town to have its housing plans rejected by the state. This was because the town had not taken the necessary steps to allow for more affordable housing. Also in 2024, the town faced money problems. These issues came from the high costs of hiring consultants and legal fees from lawsuits. Some people even thought about joining Portola Valley with the county or a nearby city.
