Reseda is a small city incorporated into the larger city of Los Angeles. The area was originally occupied by the the Tongva, a tribe that spoke a language of the Uto-Aztecan family. In 1912 the area was a farm town named Marian or Rancho Marian. By 1920, the stop on the Pacific Electric interurban railway was named Reseda. The railway ran along Sherman Way. In 1930 the population was 1,805; 1940 at 4,147; and by 1950 16,000 people. Reseda is one of the original suburbs. It's farms and ranches subdivided and developed into housing for the returning vets of WWII.

Steve Springer, in January of 2003 offered up the following information on Reseda's history:

1787: What would one day be called Reseda began it's modern history as part of the first Rancho del Encino.
1846: Eulogio de Celis purchased 121,542 acres from the Mexican government, Rancho de la Antigua Misión San Fernando.
1869: de Celis and his partners, the Pico brothers Pío and Andreas, sold most of the Valley south of present-day Roscoe Boulevard to a group of San Francisco area investors, among them Isaac Lankershim and his son-in-law Isaac Van Nuys. The syndicate managed 59,000-acres under a variety of plans (and titles), the last of which was a series of six ranches operating as the Los Angeles Farm and Milling Co. (One, Patton Ranch, approximated the future site of Reseda.)
1910: LAF&M sold its holdings to the Los Angeles Suburban Homes Co., which immediately began to subdivide. With similar subdivision going on in the north Valley, nearly 100,000 acres -- two-thirds of the Valley -- was in real estate development that year.
1911: a huge public auction of farm machinery and implements marked the end of the 40-year reign of King Wheat in the Valley.
1915: William Mulholland's water surged through a network of steel and cast-iron pipe, and the Valley changed swiftly and radically. Immense reaches of dry-land farm suddenly became small-scale, mixed truck and garden crops, alfalfa fields, walnut and avocado groves, and citrus, apricot and peach orchards. (To avail themselves of Los Angeles' Owens Valley water, Valley residents had to agree to annexation, most of which took place on May 4, 1915.)
1917: with its irrigation system completely in place, the Valley had become a nearly contiguous expanse of small (2-to-3-acre) rural lots centered on farm towns -- Marian (soon to be renamed Reseda), Owensmouth (Canoga Park), Zelzah (Northridge), Girard (Woodland Hills) -- and somewhat larger, outlying farmsteads.
By the time the first pipe load of Sierra water arrived, Reseda had been a town site for three decades. Along with Van Nuys, it had established itself as a poultry-raising center. Its outer lands were mostly in sugar beets and other field crops -- lima beans, lettuce, spinach, melons, squash, carrots -- and alfalfa, grown to fodder dairy cattle and for chicken feed.
