Foster City is among the most HOA-governed cities in California by design. Built from scratch on reclaimed tidal marsh beginning in the 1960s, the entire city was conceived as a planned community — and that planning mandate is baked into virtually every parcel. Lagoon-front townhomes, mid-rise condominiums, and cluster-home communities cover nearly every residential acre, almost all subject to HOA governance. The result is a city where HOA management isn't a niche service but a fundamental civic infrastructure.
What makes Foster City's HOA environment operationally distinctive is the levee system. The city sits below sea level in several areas and is protected by a network of levees and tide gates that are maintained partly by the City and partly by individual HOA communities, depending on parcel boundaries and historical maintenance agreements. Several lagoon-front associations carry direct maintenance obligations for levee segments adjacent to their properties — obligations that show up as substantial line items in their reserve studies and that must be coordinated with the City's own maintenance schedule and with the Army Corps of Engineers in certain jurisdictions.
Assessment budgets in Foster City reflect this infrastructure reality. Many communities here run assessments that would be considered high for equivalent square footage elsewhere on the Peninsula — and for good reason. Lagoon-maintained landscaping, private boat dock systems, and shared bulkhead infrastructure are expensive to maintain properly. The risk is not over-assessing; it's under-reserving. A Foster City HOA that carries a 60% reserve funding ratio might look financially healthy on a standard benchmark but be severely underfunded against its actual replacement liabilities.
