George F. Allardt (died July 27, 1903) was a civil engineer based in San Francisco who conducted extensive surveys of the State of California. He is most known for being the lead surveyor for the Board of Tide Land Commissioners (BTLC), which was charged with defining the high tide line for the Bay Area, thus forming the basis for the official reclamation of tidal lands in the Bay Area. Allardt was deeply involved in the survey and subdivision of 17,000 acres of the San Pablo Rancho. At the time, it was one of the largest surveys ever made in California. Moreover, he created Allardt’s Official Map of Alameda County.
