The LA neighborhood of North Hills CA has had several different names in its history. It was originally called Mission Acres in its agricultural days, then later named Sepulveda as it grew into a more residential area after WWII. North Hills CA still pays homage to the Sepulveda family with its Sepulveda Boulevard. As if all the names weren’t confusing enough, some residents prefer to refer to their neighborhood as North Hills East or North Hills West depending on what side of the freeway they live on.
