Key Highlights

Situated on the northeast slopes of Mill Valley, Scott Valley was originally part of the Rancho Corte Madera del Presidio land grant. In the early 20th century, the area operated as the Alto Ranch, a dairy farm leased in 1905 and later run by Portuguese immigrant Roque Moraes. The neighborhood’s modern residential era was unlocked by the abandonment of the Northwestern Pacific Railroad’s historic Alto Tunnel, which was completed in 1884 to pierce the Corte Madera Ridge but fell into disuse by mid-century. Residential development began in the late 1960s, shaping Scott Valley into a suburban enclave characterized by mid-century modern ranch homes on generous lots. The member-owned Scott Valley Swim & Tennis Club, established in the late 1960s, remains the community's primary social and recreational anchor.
