Key Highlights
About Islands
The Islands neighborhood (Neighborhood #5) in Foster City, California, is a residential enclave situated along the city’s central lagoon. The area's identity is anchored by "The Islands," a 174-unit condominium and townhome complex completed in the mid-1970s. Designed with a distinct waterfront orientation, the complex won the 1976 Award of Excellence from *Architectural Record* and the 1976 Award of Merit from the American Institute of Architects (AIA) and *House and Home* magazine. The neighborhood features a high density of multi-family housing, including the Winston Square and Winston Village townhomes, alongside waterfront single-family homes on Coronado and Pizarro Lanes that feature private docks. Residents enjoy localized community landmarks like the waterfront Catamaran Park and the popular Saturday morning farmers market held at Winston Square.
This residential area is characterized by its integration with the city's central lagoon system, providing residents with a unique blend of water-centric recreation and manicured suburban aesthetics. The neighborhood maintains a high visual appeal due to its well-kept lots and private waterfront access, while the complete absence of industrial activity reinforces its status as a purely residential retreat.
For those prioritizing accessibility, the neighborhood provides a highly walkable environment with clear pedestrian paths and safe crossings throughout. While housing density is moderate, the layout effectively balances community interaction with private space. The area is particularly well-suited for families and professionals who value proximity to high-performing schools and a quiet, stable atmosphere, as evidenced by the consistently high health insurance coverage and community engagement levels found in the district.
