Cybersecurity in Willowbrook, CA

Long before the name “Willowbrook” was given, willows and a slow, shallow brook separated this portion of the Los Angeles plain from the rest of it. The original rancho boundary of the 1840s was a lone, streamside willow tree along the present intersection of 125th Street and Mona Boulevard.

In the early days, springs were abundant in Willowbrook. Winter rains brought up fine ryegrass stands between gravelly ridges left by the long-ago floods of the Los Angeles River. Anastacio Avila was grazing cattle on the land as early as 1820. The Mexican governor had granted him 3,599 acres (14.56 km²) acres by 1843. The grant was called Rancho La Tajauta, and it extended from the marshes along present Alameda Street westward to approximately the present line of the Harbor Freeway. Within the area covered by Rancho La Tajauta is all of present-day Willowbrook.

In 1894 and 1895, the first subdivisions in the Willowbrook area were registered along what is now Rosecrans Avenue. The name of Willowbrook was first formally used when Willowbrook Tract was recorded by the County Recorder in 1903. Next to the tract was the recently opened Pacific Electric Railway to Long Beach. There is no indication that a townsite had been envisioned and that street patterns were not synchronized. The Willowbrook name came into use for the entire area, because Pacific Electric Railroad Company’s Big Red Cars stopped at Willowbrook’s 126th Street.
