The Native Americans already present were Ohlone and specifically the group (or groups) known as Olpen or Guemelento but these were later moved to Mission Dolores and Mission Santa Clara de Asís which claimed the land and peoples.[7][8]
The area's written history dates back to 1833, when a square league of land was given to Domingo Peralta and Máximo Martínez by Governor José Figueroa to form the Rancho Cañada del Corte de Madera.[9] In those days it was used for lumbering and cattle grazing.
By the 1880s Andrew S. Hallidie, a wire rope manufacturer, had built his country home of Eagle Home Farm in what is now Portola Valley. He built a 7,341 foot long aerial tramway from his house to the top of Skyline in 1894 though it was removed after his death in 1900.[10][11]
In 2023, two-thirds of Portola Valley government workers quit, including the town manager, after some residents lashed out at government workers over plans to build housing in the town and thee town council changed composition.[13][14] Under state law, Portola Valley is required to allow the construction of 253 new homes in the town.[13]
In March 2024, Portola Valley became the first California city or town that had its housing plans to provide more legally required lower income housing decertifed by the California Department of Housing and Community Development for failure to take the necessary steps of rezoning to carry them out.[6]
In 2024, fiscal issues arising from the higher costs of using consultants to do the jobs of employees who quit and the costs of lawsuits fighting residents who oppose new housing led some to consider dissolving Portola Valley and merging it with the county or another nearby city, Woodside.[13][15] According to the Los Angeles Times, a few years ago, about a dozen residents threatened the mayor that they would do what they could to bankrupt the city if housing plans were not to their liking.[15]
Alpine Road and Portola Road are the two relatively main roads in the town and their intersection forms a small shopping nexus.
Portola Valley can generally be divided into 7 subdivisions: Central Portola Valley, The Ranch, Corte Madera, Los Trancos/Vista Verde, Woodside Highlands, Westridge, and Blue Oaks.
According to the United States Census Bureau, the town has a total area of 9.099 square miles (23.57 km2), 99.98% of it land and 0.02% of it water.[18]
Portola Valley School is a one-room former school house built in 1909 and is on the U.S. National Register of Historic Places.[21] It is now used for town council meetings.[22]
The Alpine Inn, also known as Casa de Tableta, Rossotti's or Zott's, is one of the oldest existing drinking establishments in California; it started around 1852 when Felix Buelna built it as a gambling house.[23][24] The first two-network TCP/IP transmission was between a specialized SRI van and ARPANET on August 27, 1976; the van was parked next to the Alpine Inn and wires were run to one of the picnic tables.[25][26] In 2018, the inn was acquired by new owners, who closed it temporarily for remodeling.[27][28][29][30] It was re-opened in August 2019.[31]
Trails
Portola Valley is known for its expansive trail network both maintained by the town[32] and also in the Windy Hill Open Space Preserve maintained by the Midpeninsula Regional Open Space District.[33][34] The trail network includes the 235 acre Coal Mine Ridge Nature Preserve which is private property, but, by agreement with the town is set aside as open space.[35][36]
As of 2020, the town has a much higher percentage of white people than the rest of San Mateo county, with 75% being white as opposed to 35% in San Mateo county overall.[6] This is the result of its exclusionary zoning ordinances, which prohibit multifamily dwellings anywhere in the town.[6]

On a Sunday afternoon a few years ago, about a dozen neighbors held a meeting with Craig Hughes, who was then the mayor of Portola Valley. The backyard gathering in the small, wealthy Silicon Valley enclave was civil, Hughes said, but his constituents left an unmistakable message. If Hughes and other town leaders produced a state-mandated affordable housing plan that wasn't to the residents' liking, they should expect a battery of litigation that could lead to Portola Valley's bankruptcy.
