Lassen Street Olive Trees (Chatsworth, California)
Lassen Street Olive Trees, also known as the 76 Mature Olive Trees, are a Los Angeles Historic-Cultural Monument in Chatsworth, in the northwestern San Fernando Valley. The olive trees line Lassen Street between Topanga Canyon Boulevard and Farralone Avenue.
An alley of olive trees (Olea europaea) was planted in 1893 along the dirt road by Nelson A. Gray, who moved to Chatsworth from Pasadena in 1892. The trees are believed to have come from cuttings of Spanish Colonial olive trees planted around 1800 at Mission San Fernando Rey de España.
When the site was designated a Historic-Cultural Monument on May 10, 1967, there were 76 trees along several blocks of Lassen Street. By the 2010s, 68 trees were reported as surviving.
Governing body: City of Los Angeles. Designation: Historic-Cultural Monument No. 49.
