Villa Park Dam is an embankment dam on Santiago Creek in Orange County, California in the United States.

Construction was completed in 1963 (1963), and the dam is owned by the County of Orange.Standing 118 feet (36 m) high, the dam forms a reservoir with a maximum capacity of 15,600 acre-feet (19,200,000 m3), controlling runoff from a catchment area of 83.9 square miles (217 km2). Due to flood control requirements, the reservoir is typically at a very low level or empty during the dry season.

The Peralta Hills are a ridge of hills in northeastern Orange County, California. The ridge technically begins with Burruel Point (685 feet) in the city of Orange, close to where Nohl Ranch Road meets the Costa Mesa Freeway (SR 55), although there are hills to the west of Burruel Point, extending into the vast alluvial plain of the Los Angeles Basin to the community of Olive, California, ending roughly at the intersection of Orange-Olive Road and Lincoln Avenue. The ridge gains in elevation eastward, with peaks of 500 to 1,000 feet, until it meets the Santa Ana Mountains along the eastern boundaries of the city of Anaheim, roughly at the Eastern Transportation Corridor (SR 241). The hills are divided from the Puente Hills (home to the community of Yorba Linda to the north) by the Santa Ana River. Robbers Peak (between Serrano Avenue and Weir Canyon) is the most notable peak within the Peralta Hills, and Weir Canyon the most notable canyon.

The Canyon Fire 2, also known as the Canyon 2 Fire, was a wildfire that burned in the Anaheim Hills area of the city of Anaheim in Orange County, California. The fast-moving brush fire broke out on October 9, 2017, around 9:45 A.M. PDT near the 91 Freeway and Gypsum Canyon Road. It leaped over the Route 241 toll road, raced up a ridge, and set fire to several homes. In total, about 16,570 were ordered to evacuate their homes in Anaheim, Orange, and Tustin but returned when the evacuation order was lifted on October 12.By noon on the day the fire began, it had burned 800 acres (1.3 sq mi). By 2:30, fueled by high winds and low humidity, it had burned 2,000 acres (3.1 sq mi) and was 0 percent contained. As of 6:00 a.m. October 10 it had burned 7,500 acres (11.7 sq mi) and at least 24 structures had been damaged and a dozen homes destroyed.On October 15, the fire was reportedly 90 percent contained. A total of 9,217 acres (14.402 sq mi) had been burned, with 25 structures destroyed and another 55 damaged.Canyon Fire 2 was declared 100% contained on October 17, 2017, at 5:57 A.M. PDT. The acreage burned was 9,217. 25 structures were destroyed and 55 were damaged. An earlier fire near the border between Anaheim and Corona in late September had been called the Canyon Fire, leading to the designation of this one as Canyon Fire 2. That first fire burned approximately 2,600 acres (4.1 sq mi) but did not cause any property damage. Authorities believe the embers from the first fire and the strong winds most likely caused the second fire.

The Santiago Canyon Fire of 1889 (previously called the Great Fire of 1889) was a massive wildfire in California, which burned large parts of Orange County, Riverside County, and San Diego County during the last week of September 1889. The fire reportedly started in Fremont Canyon, a canyon close to what today is Irvine Lake. Until 2018, it was possibly the single largest wildfire in the recorded history of California, with at least 300,000 acres (1,200 km2) of land burned. In mid-August 2018, the Ranch Fire in the Mendocino Complex Fire surpassed the Santiago Canyon Fire's assumed acreage.Assistant Regional Forester (USFS) L.A. Barrett, who wrote a 1935 report on California wildfires, said of it: "I was living in Orange County at the time and well remember the great fire reported herein from September 24 to 26. Nothing like it occurred in California since the National Forests have been administered. In fact in my 33 years in the Service I have never seen a forest or brush fire to equal it. This one covered an enormous scope of country and burned very rapidly."Conditions leading up to the 1889 fire included a much longer and more severe annual drought than usual, with rains largely ceasing in March and less than 0.4 inches (1 cm) of precipitation being recorded for the 5½ months prior (records from the National Archives). This was coupled with multiple katabatic wind events (known as “northers” or Santa Anas) that month, one of which occurred about 10 days prior and likely added to the dryness of fuels. Temperatures during the week prior remained high and were coupled with several severe fires in San Diego County in which “at least 10,000 acres [40 km2] have burned over, a dwelling house consumed and other property destroyed”.
