Peters Canyon Regional Park is a regional park within the Orange County Regional Parks System in California. The park contains 354 acres of southern California wildlife, including coastal sage shrub, riparian, freshwater marsh, and grasslands, and is located within the boundaries of both Orange, California and Tustin, California. Peters Canyon was given to this city in 1992 by the Irvine Company who had used it previously for cattle grazing. The canyon is lined with a residential area on one side and open hills on the other. This canyon is commonly used by hikers, mountain bikers, and equestrians because of the trails that circumvent the 50 acre man-made lake, which was constructed by the Irvine Company in 1931, on the interior of the plot. The regional park is open from 7:00 AM to sunset every day of the week, save for the chance of rain or hazardous conditions, in which case the park will be closed for three days following the particular occurrence.The park has garnered local popularity in part for its convenient location (the canyon is in a suburban neighborhood), as well as its cleanliness and varied trail options. The management asks that visitors see protecting the park's wildlife, as well as any construction or park improvement efforts, as a shared responsibility.

Villa Park Dam is an embankment dam on Santiago Creek in Orange County, California in the United States. Along with the upstream Santiago Dam, the dam serves primarily for flood control for the cities of Villa Park, Orange, Tustin and Santa Ana and also regulates the inflow of Santiago Creek into the Santa Ana River. 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 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”.

Santiago Dam (also known as Santiago Creek Dam) is an earth/rockfill dam across Santiago Creek in Orange County, in the U.S. state of California, forming Irvine Lake.

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.
