Guano Island is the historic traditional name for this bedrock formation island and wetland area in San Francisco Bay. Guano Island is now thinly connected by causeways, fill, and bridges to various other islands. It was developed as part of the construction of Foster City. The name Guano Island has existed here since prior to the first topo maps of the 1851 survey, and continued to appear on 20th and 21st century topo maps. The Guano Island 1851 triangulation station survey monument of the US Coast and Geodetic Survey (now NGS) is on Guano Island. Guano Island triangulation station is the primary survey monument that land deeds in and around Foster City are dependent upon in the area. The base pier #1 of the San Mateo Bridge sits on the bedrock of Guano Island. In 2014, a new Foster City park was built on Guano Island. Guano was of great historical importance in the 19th century economy of this area.
