This street was laid out in April 1910 near what were then L.A.’s western city limits, hence the name. Coincidentally or not, a quip published in the Los Angeles Evening Express two months earlier read, “Pretty soon they’ll want to change Pico Street to West Boulevard or some equally fool name.” In fact Pico Street became Pico Boulevard in 1914, but I assume that anonymous journalist was commenting on all the street names in the rapidly expanding city that were “west”-obsessed (Western, Westmoreland, etc.). West Boulevard itself began south of Washington. North of Washington, its name eventually took over the former Rosemary Avenue and Sherman Drive (named for the Sherman Oaks guy: see Victoria Park Drive).
