Emergency Biohazard Cleanup Services in Monrovia, CA

Monrovia is a foothill city in Los Angeles County, tucked against the San Gabriel Mountains in the San Gabriel Valley.

Monrovia was founded in 1886, when William N. Monroe and his partners E. F. Spence, John D. Bicknell, James F. Crank and Jeremiah F. Falvey pooled their land as the Monrovia Land and Water Company; the first town lots went on sale on May 17, 1886, a date still celebrated as the city's birthday during Monrovia Days.

The town was named in William Monroe's honor, and its main street, Myrtle Avenue, was named for his daughter Myrtle; many other Monrovia streets are named for trees, among them White Oak, Lime, Lemon, Orange, Olive, Walnut and Magnolia.

Monrovia's land came out of two Mexican land grants, Rancho Azusa de Duarte, granted in 1841, and Rancho Santa Anita.

Monrovia incorporated on December 15, 1887, the fourth oldest general law city in Los Angeles County, under prohibitionist leadership determined to keep out saloons; the new government's first act was a "tippler's law" banning the sale of alcohol.

The Los Angeles and San Gabriel Valley Railroad, later part of the Santa Fe, reached Monrovia in 1887, but the land boom collapsed and the town's population fell to just 907 by 1890.

The 2020 census counted 37,931 residents in Monrovia, up from 36,590 in 2010, and Census estimates put the city at about 14,200 households.

Old Town Monrovia, along Myrtle Avenue, preserves blocks of turn-of-the-century brick buildings, including a jeweler's street clock that has been keeping time since 1921.

Monrovia Canyon Park, the city's own roughly 80-acre park in the foothills, offers streamside forest and a 30-foot waterfall that flows year-round, reached by the Canyon Falls Trail.

The Upton Sinclair House in Monrovia, home of Upton Sinclair, author of The Jungle, is a National Historic Landmark.
