Sherman Oaks, CA Sherman Oaks is a neighborhood in the San Fernando Valley region of Los Angeles, California, founded in 1927. The neighborhood includes a portion of the Santa Monica Mountains, which gives Sherman Oaks a lower population density than some other areas in Los Angeles. A partner of the Los Angeles Suburban Homes Company, Gen. Moses Hazeltine Sherman, developed Sherman Oaks. The company had subdivided 1,000 acres of land that would become Sherman Oaks. In 1927 each acre was sold for $780. Sherman’s other major venture was the Los Angeles Pacific Railroad.
