About Sterling Downs

Located east of El Camino Real and north of Ralston Avenue, the flat Sterling Downs neighborhood of Belmont, California, has a rich mid-century and wartime history. During the 1930s, the area was occupied by the Belmont Airport (also known as Belmont Landing Field), which featured an unpaved runway. During World War II, the airfield was displaced by Camp Belmont, a U.S. Army camp where the 76th Field Artillery Battalion was stationed to guard the Pacific Coast. In 1951, the airport was abandoned and subdivided for residential development. The military camp and airfield were replaced by Nesbit Elementary School and a tract of neat, post-war, single-family ranch-style cottages. Today, the neighborhood is known for its flat, accessible layout, tight-knit community, and local spaces like Alexander Park.

The area features a mix of single-family homes and multi-story apartments, creating a dense suburban environment. Residents enjoy high walkability and proximity to community staples, including St Mark Catholic Church and various restaurants along the commercial strips. According to iHuus data, the neighborhood maintains a strong sense of community, supported by well-maintained public spaces that facilitate outdoor activity for pets and pedestrians alike.

Prospective residents should weigh the benefits of the accessible, flat layout against specific environmental factors. The area experiences significant road traffic noise, and the proximity to the railway corridor introduces industrial activity that may impact acoustic comfort. Additionally, the neighborhood faces challenges regarding flood and fire safety, which are important considerations for long-term planning. It is best suited for those who prioritize walkability and a central location within the Peninsula over absolute quiet or seclusion.
