"City's Business Card" (Briefly)
San Marcos is known as the "Valley of Discovery," home to California State University San Marcos and Palomar College. It is a family-oriented suburban city with master-planned communities, offering a quieter alternative to the coast while still being part of the dynamic San Diego metropolitan area. Its identity is shaped by education, suburban living, and the beautiful inland valleys of North County.
History
The history of San Marcos dates back to the late 18th century. According to legend, the valley was named Los Vallecitos de San Marcos by Spanish soldiers in 1797. While pursuing Native Americans who had allegedly robbed the San Luis Rey Mission, they came upon the valley on April 25, St. Mark's Day, and named it in his honor .
In 1840, Governor Juan B. Alvarado of Mexican California granted the Rancho Vallecitos de San Marcos to his relative, José María Alvarado. After José's death, the land was eventually sold to Cave Couts, a prominent regional landowner. The first permanent American settler was Major Gustavus French Merriam, who homesteaded land in the Twin Oaks Valley in the late 1850s and began producing wine and honey .
The town of Barham was founded in 1883 by John H. Barham near what is now San Marcos Boulevard. It had a post office, a newspaper, and a blacksmith. However, when the Santa Fe Railroad laid tracks through the valley in 1887, it bypassed Barham by a mile. The town of San Marcos was then established closer to the depot, at the intersection of what is now Grand Avenue and Rancho Santa Fe Road. By 1903, to be even closer to the railroad, residents physically moved many of their buildings about two miles east to their current location along Mission Road .
For most of the 19th and first half of the 20th centuries, San Marcos was an agricultural community focused on farming, and later, dairy and poultry. The arrival of water from the Colorado River in 1956 spurred a period of rapid growth. The community, feeling the pressures of development, incorporated as the City of San Marcos on January 28, 1963, to have more local control. The opening of Palomar College in 1946 and Cal State San Marcos in 1989 cemented its identity as an educational hub, and its population boomed from under 4,000 in 1970 to nearly 95,000 in 2020 .
Geography
Mountains and Hills
While there are no major mountain peaks within the city limits, San Marcos is nestled in a series of coastal valleys surrounded by hills.
