The Mission Vieja or Misión Vieja or the Old Mission was the first Spanish mission in the San Gabriel Valley. Mission Vieja was built in 1771 by what would become the fathers of the Mission San Gabriel Arcángel. The Mission Vieja site was designated a California Historic Landmark (No.161) on Jan. 11, 1935. The location of Mission Vieja is at what is now the South West corner North San Gabriel Blvd and North Lincoln Ave in Montebello, California. The site has a plaque marker and an El Camino Real Bell. Mission Vieja was the first building in the San Gabriel Valley and Los Angeles County. Father Juan Crespí picked the spot for Mission Vieja because water was available at what is now called the Whittier Narrows. The place for Mission Vieja was found in the expedition of Portolá in the summer of 1769. Gaspar de Portolá, Miguel Costansó and Father Juan Crespí recorded the expedition. In 1771 the fathers of Pedro Cambon and the fathers of Angel Somera, with a decree from Governor Pedro Fages, set out to build a mission in the Spanish Empire of Alta California, in what is now called the Los Angeles Basin. The first building was 45 by 18 feet made of adobe and wood. The roof was made with tule reeds from the waters of the Whittier Narrows. The building had around it a weak Palisade fence. Father Angel Somera and Father Pedro Cambon, both Franciscan missionaries, founded Mission Vieja, the original Mission San Gabriel Arcangel, on September 8, 1771; the location is today near the intersection of San Gabriel Boulevard and the Rio Hondo River. The establishment of the mission marked the beginning of the Los Angeles region's settlement by Spaniards and the fourth of twenty-one missions ultimately established along California's El Camino Real. The mission did well initially as a farm and cattle ranch. Six years after its founding, however, a destructive flood in 1776 led the mission fathers to relocate the mission five miles north, to its current location in what is the present day City of San Gabriel.During the early years of the mission's existence, the region operated under a "Rancho" land grant system. The current city of Montebello consists of land from Rancho San Antonio, Rancho La Merced, and Rancho Paso de Bartolo. The Juan Matias Sanchez Adobe, built in 1844, still stands at the center of old Rancho la Merced in East Montebello. Recently restored, Rancho la Merced is the Montebello's oldest standing structure.

Whittier Narrows Dam is a 56-foot (17 m) tall earth dam on the San Gabriel River and the smaller, parallel Rio Hondo. The dam is located, as the name implies, at the Whittier Narrows. It provides water conservation storage and is also the central element of the Los Angeles County Drainage Area (LACDA) flood control system. Its reservoir has a capacity of 67,060 acre⋅ft (82,720,000 m3). The Whittier Narrows are a natural gap in the hills that form the southern boundary of the San Gabriel Valley of Southern California. Both the Rio Hondo, a tributary of the Los Angeles River, and the San Gabriel River flow through this gap and are impounded by the reservoir. The Pomona Freeway (CA-60) passes through the reservoir flood control basin and the San Gabriel River Freeway (I-605) passes along the eastern boundary of the basin. In September 2017, the United States Army Corps of Engineers officials warned local residents that the dam no longer met the agency’s 'tolerable-risk' guidelines and could fail in the event of a very large, very rare storm, similar to exceptionally intense California storms which occurred between December 1861 and January 1862, a so-called ARkStormAuthorization for the project construction is contained in the Flood Control Act of 18 August 1941 (PL 77-228) and the initial funds for construction were provided in the 1949 Appropriations Bill. The U.S. Army Corps of Engineers completed construction of the dam in 1957.
