Spring Valley is a historic neighborhood in Toluca Lake, bordered by Forman Avenue, Valley Spring Lane, Ledge Avenue, and Moorpark Street. Originally envisioned as a community of large estates, the land was sold in roughly one-acre parcels, with multiple parcels encouraged for those seeking expansive properties. In its early days, it was anticipated that many residents would keep horses, taking advantage of the open spaces and proximity to the Los Angeles River for leisurely rides. Up until the 1950s, horses were a common sight in Spring Valley, a reminder of its equestrian roots. A nostalgic nod to that era still exists in the form of a "No Horses on Sidewalk" sign on Toluca Lake Avenue.

The neighborhood’s original name, "Spring Valley," reflected its natural geography. In the 1930s, heavy rains would fill the natural riverbeds along Whipple Street and Woodbridge Street, creating a seasonal pond fed by bubbling natural springs. These events brought life to the valley’s name, although the moniker was eventually dropped as the area evolved into a more suburban setting.

Today, Spring Valley retains its charm with a mix of historic homes and large estates, offering residents a tranquil, tree-lined environment with a rich history. While the horses and seasonal pond are no longer part of everyday life, the neighborhood’s character remains deeply rooted in its past, making it a unique and cherished part of the greater Toluca Lake and Studio City area.
