Security Guard in Eagle Rock, CA

Before the arrival of European settlers, the secluded valley below the San Rafael Hills that is roughly congruent to Eagle Rock’s present boundaries was inhabited by the Tongva people, whose staple food was the acorns from the valley’s many oak trees. These aboriginal inhabitants were displaced by Spanish settlers in the late 18th century, with the area incorporated into the Rancho San Rafael. Following court battles, the area known as Rancho San Rafael was divided into 31 parcels in 1870. Benjamin Dreyfus was awarded what is now called Eagle Rock. In the 1880s Eagle Rock existed as a farming community.

The arrival of American settlers and the growth of Los Angeles resulted in steadily increasing semi-rural development in the region throughout the late 19th century. The construction of Henry Huntington’s Los Angeles Railway trolley line up Eagle Rock Boulevard to Colorado Boulevard and on Colorado to Townsend Avenue commenced the rapid suburbanization of the Eagle Rock Valley.

Although Eagle Rock-which is geographically located between the cities of Pasadena and Glendale-was once incorporated as Eagle Rock City in 1911, it was thereafter annexed to the City of Los Angeles in 1923 due to need for an adequate water supply and a high school.
