By the turn of the century, the West Park Commission was riddled with political graft, and the three parks became dilapidated. As part of a reform effort in 1905, Jens Jensen was appointed as General Superintendent and Chief Landscape Architect for the entire West Park System. Jensen, now recognized as dean of the prairie style of landscape architecture, improved deteriorating sections of the parks and added new features. Among Jensen's improvements were a semi-circular entryway at Marshall Boulevard, and a formal garden at the corner of Ogden Avenue and Sacramento Drive. By the time Jensen designed the garden, Ogden Avenue, a diagonal roadway with a major streetcar thoroughfare that would later become part of Route 66, had already been constructed. The road divided the park into two separate landscapes, creating a busy intersection at the junction of Ogden and Sacramento Avenues. Jensen's solution was a long axial garden on the southeast side of the intersection, providing a buffer between Ogden Avenue and playing fields to the south. Jensen demolished the conservatories in each of the West Park System parks in favor of one grand conservatory at Garfield Park.
