About San Marcos

Also known as. Valley of Discovery. The education hub of North County.

History. Named on April 25, 1797, when Spanish troops came upon a fertile valley and called it 'Los Vallecitos de San Marcos' to honor St. Mark's Day. The original Rancho Vallecitos de San Marcos land grant was awarded on April 22, 1840, to Jose Maria Alvarado. Established as a settlement in the late 19th century known for dairy and poultry farming; the townsite was relocated about one mile to be near the railroad in 1903. The arrival of Colorado River water in 1956 sparked rapid growth, with the population jumping to about 2,500. Incorporated as a city on January 28, 1963, and became a charter city on July 4, 1994. San Marcos was the third fastest-growing city in California during the 1970s, reaching a population of 17,479 by 1980.

Local economy. The San Marcos Unified School District is the largest employer with about 2,464 employees serving more than 21,000 students across 20 schools. California State University San Marcos employs about 1,800 people; Palomar College employs about 1,769. Hunter Industries, an irrigation-equipment manufacturer, employs about 815 people locally. UPS operates a facility employing about 551 people. The city's economy shifted from mid-20th-century dairy and poultry production to education, manufacturing, and services; the 2023 median household income was about $105,286.

Culture and community. Old California Restaurant Row, built in Spanish Colonial style to resemble an old-world village, is North County's largest dining and entertainment complex with about 15 restaurants and an 18-screen Edwards cinema. The San Marcos Harvest Festival has been a premier city celebration since the 1990s, drawing more than 15,000 people for booths, food, live music, and carnival rides. The city hosts a large summer festival with live music, arts and crafts, food, and a car show. Notable people from San Marcos include NFL players Fred Warner and Terrell Burgess, WWE wrestler Nia Jax, actress Liliana Mumy, and 'Luann' cartoonist Greg Evans.

What makes San Marcos distinct. The town was physically relocated twice, including a one-mile move in 1903 to sit closer to the railroad. The nickname 'Valley of Discovery' comes directly from the 1797 St. Mark's Day discovery of the valley by Spanish troops. The illuminated cross above Lake San Marcos and the giant Palomar College 'P' on the hillside are both long-time visual landmarks visible from across the valley. The SPRINTER light rail links the two colleges, with stations at Palomar College and Cal State San Marcos, reflecting the city's 'education hub' identity.

San Marcos is a growing suburban city in North County San Diego that is home to two colleges and calls itself the Valley of Discovery.
