Sherman Oaks, Los Angeles. Sherman Oaks is a neighborhood in the San Fernando Valley region of Los Angeles, California, founded in 1927 with boundary changes afterward. 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.
Building codes and research findings do not completely agree over how to place handrails so they might serve the above functions. Research done by Maki and Fernie (1988) indicates a handrail height of 36 to 40 inches is most effective in preventing falls when descending stairs.
Current versions of these codes and standards now agree that handrail is defined as either a circular cross section with an outside diameter of 1Â¼ (32 mm) minimum and 2 (51 mm) maximum or a non-circular cross section with a perimeter dimension of 4 (100 mm) minimum and 6Â¼ (160 mm) maximum and a cross section dimension of 2Â¼ (57 mm) maximum.
