Cooper Park History

The Namesake

Deborah Cooper (1952-1986) embodied the giving spirit of Jefferson City. Along with her dedicated employment with Central Bank, Mrs. Cooper was also involved with United Way of Central Missouri and City of Jefferson Environmental Quality Commission. Upon her death, the Deborah Cooper Historical Memorial Park Foundation was established. Foundation contributions were donated to the development of a park on Adrian’s Island.


The Island

Wing dikes were constructed in the 1960’s by the Corps of Engineers along the Missouri River on the south bank of the State Capitol. Over time, sand and dirt from the river amassed, creating and “island”. The Adrian family became owners of the newly formed land in 1967, then gifted the land to Jefferson City Housing Authority in 1974. In 2019, the Housing Authority sold Adrian’s Island to City of Jefferson, care of the Parks and Recreation Department, for $10.00. The agreement included clauses to use the name of “Deborah Cooper Park” as well as “Adrian” when referring to the property.
