Prado Dam is an earth-fill dry dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 mi (49.1 km) upstream from the ocean. The area upstream from the dam contains 2,255 sq mi (5,840 km2) of the watershed's 2,650 sq mi (6,900 km2). The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. Prado Flood Control Basin also provides water storage for groundwater recharge operations.

The school site occupies over 70 acres (280,000 m2) and has over 170,000 square feet (16,000 m2) of classroom and administrative space, including a library, gymnasium, performing arts spaces, a pool, an adjacent joint-use park, baseball fields, and a large stadium facility.

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 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.
