[3] The 2000 U.S. census counted 57,561 residents in the 9.47-square-mile (24.5 km2) Northridge neighborhood—or 6,080 people per square mile (2,350/km2), among the lowest population densities for the city.Mexico (24.7%) and the Philippines (9.8%) were the most common places of birth for the 31.8% of the residents who were born abroad—an average figure for Los Angeles.[9] In the late 1840s, Mexican Governor Pio Pico broke with the tradition of "granting" land and, instead, sold it, without the usual area limitations, to Eulogio de Celis, a native of Spain.The Zelzah Train Station or Depot was built on the site that is now the northwest corner of Parthenia Avenue and Reseda Boulevard, across the street from the water well.Also in 1910, on January 13, the large balloon America landed on the so-called Zelzah ranch after a 31-mile (50 km) trip from Huntington Park.[13] The company advertised the acres as the "cream of the San Fernando valley, the richest soil in California," describing the ease of transportation provided by the station, the lack of alkali, adobe or hardpan soil, and stating that water for domestic purposes could be welled from 35 to 65 feet and at 140 to 300 feet for general irrigation; water would later become a major selling point for land in the valley after the arrival of the Los Angeles Aqueduct.[18][19] The community began to develop rapidly after World War II and agricultural lots were subdivided into suburban housing tracts to meet the demand for single-family homes by veterans and their families.[18] Thirty-four percent of Northridge residents aged 25 and older had earned a four-year degree by 2000, an average percentage for the city but high for the county.[28] Silent star Janet Gaynor and her costume-designer husband Adrian were the first owners of a spacious estate in Northridge, which was later sold to Barbara Stanwyck and Robert Taylor.The Oakie house was set for the wrecking ball, but in 2010 the city agreed to buy the Tudor-style stone landmark and its 10-acre (40,000 m2) ranch estate.The little-known two-day 1967 Fantasy Faire and Magic Music Festival (at "Devonshire Meadows") featured The Doors, Jefferson Airplane, Country Joe and the Fish, The Grass Roots, Canned Heat, Iron Butterfly and several other bands.[30] The better-known but confusingly named 1969 Newport Pop Festival was a massive three-day event that featured Jimi Hendrix and many other top acts.Like its famous successor, it had problems with large numbers of gate-crashers, and some young attendees far from home camped out nearby in sleeping bags.Unlike Woodstock, "nearby" included parts of suburban Northridge, where most of the local residents were horrified to find their neighborhoods invaded by "hippies".
