The District is situated in the southeasterly portion of Rancho de las Pulgas, in what is now San Mateo County. In 1851, Dennis J. Oliver and his brother-in-law, D.C. McGlyn, had acquired about 1, 700 acres of the rancho. Three years later, at a point just south of where Santa Cruz Avenue now enters El Camino Real, they erected a gate with an arch bearing the words Menlo Park, August 1854.
