Laguna Woods (Laguna, Spanish for "Lagoon") is a city in Orange County, California, United States. The population was 16,192 at the 2010 census, down from 16,507 at the 2000 census with a median age of 78. About ninety percent of the city consists of Laguna Woods Village, a private gated retirement community, formerly known as Leisure World. The other ten percent consists of businesses and the city hall, which are available to the public. Incorporation efforts in the late 1990s were largely driven by the need for residents to have a stronger voice against the prospective construction of an international airport at the nearby decommissioned Marine Corps Air Station El Toro. The airport proposal was defeated and the land in question has been tabbed for development as the Orange County Great Park.

The Laguna Woods shooting was a mass shooting that occurred on May 15, 2022, at the Geneva Presbyterian Church in Laguna Woods, California, United States.

A suspect, 68-year-old David Chou of Las Vegas, was arrested at the scene. Authorities allege that the crime was committed out of a political hatred of Taiwan and the Taiwanese people. Chou has been charged with one count of murder and five counts of attempted murder, all with hate crime enhancements, and four counts of possessing an explosive device.

Area code 949 is an area code in California that is contained within South Orange County California. On April 18, 1998, the southern cities of Orange County were split from 714, creating area code 949. It includes some of the wealthiest communities in California; including such cities as Newport Beach, Irvine, Lake Forest, Portola Hills, Coto de Caza, Dove Canyon, Aliso Viejo, Trabuco Canyon, Capistrano Beach, Corona Del Mar, Laguna Niguel, Laguna Hills, Laguna Woods, Newport Coast, Foothill Ranch, Robinson Ranch, Mission Viejo, San Juan Capistrano, Rancho Santa Margarita, Ladera Ranch, Dana Point, Laguna Beach, and San Clemente. The city of Costa Mesa is shared between the 949 and 714 area codes, being split at Wilson Street and along Newport Boulevard. A very small portion of Irvine is also in the 714 area code, from the north side of Culver Drive at the I-5 to Jamboree Road in the Marketplace, in the neighborhood of Northpark Irvine.

The Monterey Formation is an extensive Miocene oil-rich geological sedimentary formation in California, with outcrops of the formation in parts of the California Coast Ranges, Peninsular Ranges, and on some of California's off-shore islands. The type locality is near the city of Monterey, California. The Monterey Formation is the major source-rock for 37 to 38 billion barrels of oil in conventional traps such as sandstones. This is most of California's known oil resources. The Monterey has been extensively investigated and mapped for petroleum potential, and is of major importance for understanding the complex geological history of California. Its rocks are mostly highly siliceous strata that vary greatly in composition, stratigraphy, and tectono-stratigraphic history. The US Energy Information Administration (EIA) estimated in 2014 that the 1,750 square mile Monterey Formation could, as an unconventional resource, yield about 600 million barrels of oil, from tight oil contained in the formation, down sharply from their 2011 estimate of a potential 15.4 billion barrels. An independent review by the California Council on Science and Technology found both of these estimates to be "highly uncertain." Despite intense industry efforts, there has been little success to date (2013) in producing Monterey-hosted tight oil/shale oil, except in places where it is already naturally fractured, and it may be many years, if ever, before the Monterey becomes a significant producer of shale oil. The Monterey Formation strata vary. Its lower Miocene members show indications of weak coastal upwelling, with fossil assemblages and calcareous-siliceous rocks formed from diatoms and coccolithophorids. Its middle and upper Miocene upwelling-rich assemblages, and its unique highly siliceous rocks from diatom-rich plankton, became diatomites, porcelainites, and banded cherts.

Laguna Hills (; Laguna, Spanish for "Lagoon") is a city in Orange County, California, United States. Its name refers to its proximity to Laguna Canyon and the much older Laguna Beach. Other newer cities nearby—Laguna Niguel and Laguna Woods—are similarly named.

The El Toro "Y" is a freeway interchange in southern Orange County, California where the Santa Ana Freeway, Interstate 5 (I-5), and the San Diego Freeway (at that point the I-405) merge. South of the El Toro Y, the highway is named the "San Diego Freeway" with the highway designation "I-5." Located in south Orange County where the cities of Lake Forest, Laguna Hills, and Irvine converge, the interchange was named after the nearby city (El Toro - now Lake Forest) and the now-closed Marine Corps Air Station El Toro, located northeast of the interchange. The "Y" is one of the busiest interchanges in the world; from 1975 to 2002, daily traffic surged from 102,000 to 356,000 vehicles a day.The "Y" was where American broadcast reporter Zoey Tur of KCBS-TV, via news helicopter, first located and broadcast O.J. Simpson's white Ford Bronco slow-speed police chase exclusively for 22 minutes on June 17, 1994.

Laguna Hills Technology Branch Library is one of two "technology branches" within the 33-branch Orange County Public Libraries (OCPL) system.

Serrano Creek is a roughly 7.5-mile (12.1 km) tributary of San Diego Creek in the U.S. state of California. The creek starts in the Santa Ana Mountains in a canyon in Whiting Ranch Wilderness Park, near the boundary of the Cleveland National Forest. It then flows southwest into the city of Lake Forest, running in a channelized course roughly parallel to Aliso Creek. It abruptly turns northwest then southwest at 90-degree angles as it enters a large storm drain that takes it the rest of the way to the confluence with the La Cañada Channel, creating the main stem of San Diego Creek.
