Irvine, California

• 1. Indigenous And Colonial History

  ›

  The Kizh people, also known as the Tongva or Gabrieleño, inhabited the land that is now Irvine for thousands of years before European contact. In 2024, a proposal emerged to create a village based on Putuidem Village located in San Juan Capistrano to honor this history. The city and its schools are currently taking action to educate the community about these indigenous roots. Spanish explorer Gaspar de Portolá arrived in the area in 1769, leading to the establishment of forts, missions, and cattle herds. The King of Spain parceled out land for both mission use and private ownership during this era. After Mexico gained independence from Spain in 1821, the Mexican Congress passed the secularization act of 1833. This law secularized the missions and transferred control of mission lands to the Mexican government. The government then began distributing these lands to citizens who applied for grants. Three large ranchos eventually made up the territory that became the Irvine Ranch: Rancho Santiago de Santa Ana, Rancho San Joaquín, and Rancho Lomas de Santiago. In 1864, José Andrés Sepúlveda sold part of Rancho San Joaquín to Benjamin Flint, Thomas Flint, Llewellyn Bixby, and James Irvine for $18,000 to resolve debts caused by the Great Drought. Two years later, the group acquired Rancho Lomas de Santiago for $7,000. Following the Mexican-American War, titles to Rancho Santiago de Santa Ana became tangled in legal disputes. By 1868, the ranch was divided among three claimants including Flint, Bixby, and Irvine as part of a lawsuit. These ranches were initially devoted to sheep grazing until tenant farming was permitted in 1870. James Irvine bought out his partners' interests in 1878 for $150,000. His property stretched from the Pacific Ocean to the Santa Ana River. He died in 1886, leaving the ranch to his son James Irvine II. The younger Irvine shifted operations to field crops, olives, and citrus fruits. In 1888, the Santa Fe Railroad extended its line to Fallbrook Junction and named a station after James Irvine. A town formed around this station called Myford, named after Irvine's son, because a post office in Calaveras County already used the family name. The town was renamed Irvine in 1914.

• 2. Planned City Development

  ›

  The Irvine Company began developing the area in the 1960s under the guidance of architect William Pereira. Pereira and company employee Raymond Watson designed the city layout starting in the late 1950s. They created a plan for a community of 50,000 people surrounding a new university campus. The design included industrial zones, residential areas, recreational spaces, commercial centers, and greenbelts. The city was divided into townships called villages separated by six-lane arterial roads. Each township contained houses with similar designs along with schools and religious institutions. Commercial districts were checkerboarded around the central townships. The original plan envisioned the university at the northern end of the Irvine Ranch. When the Irvine Company refused to give up valuable farmland in the flat central region, the site moved to the base of the southern coastal hills. The final layout resembled a necklace with villages strung along two parallel streets ending at the University of California, Irvine. Residential areas are now bordered by two commercial districts: the Irvine Business Complex to the west and Irvine Spectrum to the east. All streets feature landscaping allowances while powerline rights-of-way serve as bicycle corridors and parks. The city irrigates its greenery using reclaimed water. Homeowners associations govern some village neighborhoods with varying degrees of control over home appearances. In more restrictive areas, roofing, paint colors, and landscaping are strictly regulated. Older parts of the Village of Northwood developed independently in the early 1970s without homeowners' associations. Tightly regulated villages generally offer more amenities like members-only swimming pools and tennis courts. Residents in villages built during the 1980s or later may pay Mello-Roos special taxes following Proposition 13. The first phases of Turtle Rock, University Park, Westpark, El Camino Real, and Walnut villages were completed by 1970. On the 28th of December 1971, residents voted to incorporate a substantially larger city than Pereira's original vision. By January 1999, Irvine had reached a population of 134,000 across its total area.

In 2006, median gross rent was $1,660 monthly making it the highest for any US place with over 100,000 people. The city council faces pressure to approve future income-subsidized housing projects due to skyrocketing costs. University Hills offers subsidized pricing 20-30% below market value specifically for professors and retired faculty. This community represents the first such initiative of its kind nationwide. Age distribution shows 21.0% under age 18 and 30.7% between ages 25 and 44 as of recent counts. For every 100 females there were 95.9 males overall with a median age of 34.3 years.
