Brookside and Willowbrook Portola Valley Homes and Neighborhood Guide
Also known as Brookside Park, Willowbrook
Portola Valley neighborhood guide
Brookside and Willowbrook sit in the triangle where Alpine Road and Portola Road meet, with Willowbrook Drive on the west side. It is one of the closest parts of town to Corte Madera School, the Alpine Road shops and Interstate 280.
Brookside Park was subdivided in the 1920s and 1930s, when many lots held vacation cottages. Willowbrook takes its name from Willowbrook Farm, which Herbert Law bought in 1912: 61 acres between Portola and Willowbrook roads reaching Alpine Road. The farm's stone superintendent's house still stands at 451 Portola Road, and the superintendent's house and office are the only Willowbrook Farm buildings that remain.
