Unattended Death and Biohazard Cleanup in Wildomar, CA

Wildomar's name is a portmanteau of its three founders — Wil for William Collier, do for Donald Graham, and mar for Margaret Collier Graham — stitched together when the townsite was mapped in December 1885.

Wildomar's roots trace to September 24, 1883, when Franklin Heald, William Collier, and Donald Graham bought the 12,832-acre Rancho La Laguna from the London and San Francisco Bank.

Wildomar's first railroad depot, opened on January 1, 1884, was simply a boxcar known as "Car B" set beside the California Southern Railroad tracks.

By 1887 Wildomar could boast a large hotel, a livery stable, a blacksmith shop, stores, a lumber yard, and a park, and by the early 1900s it even had its own newspaper, The Transcript.

When rail service was abandoned in 1935 and the tracks torn up, Wildomar faded into near obscurity for decades, until the completion of Interstate 15 in the early 1980s sparked a new building boom.

Wildomar was also once known as an important center for honey production in Riverside County.

Wildomar is one of California's youngest cities — voters in Wildomar and Sedco Hills approved incorporation on February 5, 2008, and it officially became Riverside County's 25th city on July 1, 2008.

Wildomar had a population of 36,875 at the 2020 census, more than two and a half times the 14,064 people counted in 2000 when it was still an unincorporated community.

Wildomar's 11,267 households average about 3.26 people each, and Census QuickFacts reports a median household income of about $103,506 with a 78.3% owner-occupancy rate.

The city of Wildomar sprawls across about 23.7 square miles of southwestern Riverside County, making it far larger in land area than most of its Temecula Valley neighbors are in population density.
