Emergency Biohazard Cleanup Services in Irwindale, CA

Irwindale is a small city in the San Gabriel Valley of Los Angeles County, about 20 miles east of downtown Los Angeles, covering roughly 9.6 square miles.

The area was first settled in the 1850s by the families of Gregorio Fraijo and Fecundo Ayon on former Mexican land grants — Rancho La Puente, Rancho Azusa de Dalton, Rancho Azusa de Duarte, and Rancho San Francisquito — and Irwindale counts its founding from 1860.

Irwindale incorporated on August 6, 1957, becoming Los Angeles County's 56th municipality, largely to control the sand and gravel riches within its borders.

Irwindale's Spanish nickname is "Jardin de Roca" — Garden of Rocks — because more than a dozen sand and gravel pits, some as deep as 275 feet, dominate its landscape.

Those rock quarries are the city's major revenue source and supplied much of the aggregate that paved Southern California's freeways as the automobile age drove up demand for crushed rock and sand.

Despite its industrial footprint, Irwindale is one of Los Angeles County's smallest cities by population: just 1,472 people at the 2020 census, living in 412 households that average a large 3.5 people each.

More than 90% of Irwindale's residents are Latino, and many descend from the same Fraijo and Ayon families who settled the area in the 1850s — seven generations of them have lived in the city.

Tiny as its population is, Irwindale hosts roughly 700 businesses employing about 25,000 people, including a 200-acre Miller Brewing Company plant that arrived during the city's redevelopment boom.

The Irwindale Speedway and Event Center — a NASCAR-sanctioned racetrack — was built on top of a reclaimed gravel quarry, turning one of the city's pits into its best-known attraction.

Huy Fong Foods makes its world-famous Sriracha hot sauce at a plant in Irwindale, after the city offered the company a low-interest loan in 2010 to relocate there.
