This secluded park features a 22-foot waterfall in the middle of Pioneer Square. The Annie E. Casey Foundation paid for this small "pocket park". It was designed by Masao Kinoshita within the firm of Sasaki Associates, Incorporated, Landscape Architects, of Watertown, MA. It was called "Waterfall Park," "Waterfall Garden" or "UPS [United Parcel Service] Park," as it was located on the site of the first UPS headquarters in Seattle's Pioneer Square Neighborhood in 1907. The Anne E. Casey Foundation of Seattle, WA, formed as a result of largesse from UPS, has maintained the park since its completion in 08/1978.
