This 1864 diagram of the changing Lake Michigan shoreline anticipates expansion based on the ongoing accretions that were superceded by Streeterville's landfill. Ultimately, the entire Chicago shoreline was built out for the addition of Lake Shore Drive. John Walls (topmost dotted line) surveyed the area in 1821.

This packet from 1904, presented by permission and courtesy of the Chicago Park District Special Collections, details aspects of the construction of Lake Shore Drive running along the Streeterville area that re-defined the evolving accretions as diagrammed, above.
