Foster City is a master-planned city located in San Mateo County, California, United States. Foster City is sometimes considered to be part of Silicon Valley for its local industry and its proximity to Silicon Valley cities.

The 2020 census put the population at 33,805, an increase of more than 10% over the 2010 census figure of 30,567.

History

Foster City was founded in the 1960s, built on the existing Brewer Island in the marshes of the San Francisco Bay on the east edge of San Mateo, enlarged with engineered landfill. The city was named after T. Jack Foster, a real estate magnate who owned much of the land comprising the city and who was instrumental in its initial design. His firm, Foster Enterprises, now run by his descendants, relocated to San Mateo in 2000 and is still active in real estate affairs throughout the San Francisco Bay Area.

The first residents moved into Foster City on March 7, 1964. Charles Zerbe, a San Francisco firefighter with a wife and two young sons, paid $23,500 for his five-bedroom house on Pilgrim Drive.

In the early 1960s, the first homes built in Foster City were sold for under $18,000. By the late 1960s, the average home price was just under $30,000. United States census data shows the median household income for Foster City residents in 1970 was $30,000 and in 1980 was $60,000. As of 2020, the median household income for Foster City was $161,000. In 2024, the average home value was $1,926,381.

Geography

According to the United States Census Bureau, the city has a total area of 19.8 square miles (51 km2), of which 3.8 square miles (9.8 km2) is land and 16.1 square miles (42 km2) is water. The total area is 81.07% water. Foster City has ongoing issues with water intrusion from the San Francisco Bay and is potentially subject to permanent inundation as the sea level rises. A project to improve the existing levee with a steel-reinforced wall has been underway since FEMA designated the entire area as a floodplain making residents subject to much higher flood insurance rates.

Climate

Foster City, like most of the peninsula, has a mild warm-summer Mediterranean climate, with warm, dry summers and cool, wet winters. The warmest month of the year is September, with an average daytime temperature of 77.8 °F (25.4 °C) and an average nighttime temperature of 53.8 °F (12.1 °C), while the coldest month of the year is January, with an average daytime temperature of 58 °F (14 °C) and an average nighttime temperature of 41.5 °F (5.3 °C).
