Trampas Canyon is a short tributary of San Juan Creek in southern Orange County the U.S. state of California. It rises in forks on steep slopes of the southern Santa Ana Mountains (33.4883597°N 117.5933813°W / 33.4883597; -117.5933813), and flows north to where it is dammed by Trampas Canyon Dam (USGS San Clemente Quad 7½"). Trampas Canyon 1795-006 Dam (33.498359°N 117.587548°W / 33.498359; -117.587548) forms a small lake that branches into four forks running east–west. Exiting the dam, the creek flows north and turns slightly to the west, where it joins San Juan Creek on the left bank, near the confluence of Cañada Gobernadora (33.3053°N 117.3458°W / 33.3053; -117.3458). Trampas Canyon Creek is ephemeral and only flows during storm events or while Trampas Canyon Dam is releasing, and is not a primary tributary of San Juan Creek.A study was prepared in 1999 by the City of San Juan Capistrano, and it was found that a failure of the earthen Trampas Canyon Dam would do more damage to the lower course of San Juan Creek than for a 100 year flood. A failure would cause a floodwave over 0.5 miles (0.80 km) wide to rush down the lower 4.7 miles (7.6 km) of San Juan Creek to Doheny State Beach, flooding parts of San Juan Capistrano and Dana Point. A 100-year flood would cause a slightly smaller inundation.

The Frank A. Forster House in San Juan Capistrano, California is a 6,000-square-foot (560 m2) stucco, Spanish tile roofed mansion built in 1910 for $10,000 by Frank Ambrosio Foster, grandson of rancher John (Don Juan) Forster. It is the only remaining home of its style and era in the area. It was designed as a 5-bedroom, 1-bathroom home in the Mission Revival style by Los Angeles architects Robert Farquhar Train and Robert Edmund Williams (Train & Williams). Upon the deaths of Frank and his wife Ada, their daughter Alice Forster Leck inherited the house, and bequeathed it to her nephew Pancho Forster.The property changed owners in 1975, and was purchased as a fixer-upper in 1983 by interior designer Martha Gresham, who traded two Porterville ranches for the house. It came with a legend of a ghost, nicknamed "George the Ghost" by Gresham. She spent $350,000 restoring the mansion, and used it as a home and office until 1990 when she sold it to photographer Phillip Stewart Charis.The mansion is a San Juan Capistrano Historic and Cultural Landmark. It was added to the National Register of Historic Places listings in Orange County, California in 1986.

El Horno Creek or Horno Creek (Spanish: "Oven Creek") is a tributary stream of San Juan Creek in Orange County in the U.S. state of California. It is approximately 5.9 miles (9.5 km) long and drains an area of 4.3 square miles (11 km2). The creek joins San Juan Creek on the right bank, only a few hundred yards upstream of the Trabuco Creek confluence, within the city limits of San Juan Capistrano. The creek begins in the foothills of the Santa Ana Mountains (33.5672464°N 117.6300495°W / 33.5672464; -117.6300495), in the mostly residential CDP of Ladera Ranch. The headwaters of the creek were formerly divided into two canyons, but during the development of Ladera Ranch starting in the late 1990s the area was regraded, and the headwaters combined into a single 2.4-mile (3.9 km) channel. The creek flows southwest through a small flood control dam and into San Juan Capistrano, where it crosses under Interstate 5 and turns south, bisecting San Juan Elementary School. Shortly past the school the creek enters an underground concrete channel passing under the I-5/CA 74 interchange and flows into San Juan Creek at (33.4978044°N 117.6553283°W / 33.4978044; -117.6553283). Although significant stretches of the creek remain above ground, riparian habitat along the creek remains "sporadic" despite its perennial flow mainly due to pollution from stormwater.

The Spanish missionaries constructed Mission San Juan Capistrano less than 60 yards from the village in 1776. Acjachemen is a pluralization of the word Acjacheme, and became the moniker for the people overall after the mission period. The village has also been referred to as Akhachmai, Ahachmai, Akagchemem, Acágcheme, and Axatcme. The village site has been identified as being at an elementary school east of the Mission San Juan Capistrano by José de Grácia Cruz, who was one of the last native people born at the mission in the 1840s. Ahachmai has been referred to as a dialect or variety of the Acjachemen language and is used, although less commonly, to refer to the people as a whole.
