General Information / History
Originally referred to as the Adie Road park site, the site was purchased with 1977 Bond Issue funds and declared a County Park in 1978. On October 19, 1980 an ordinance was passed that officially changed the name to James S. McDonnell Memorial County Park in honor of the late founder of McDonnell Douglas Aircraft. 

A new playground was completed in 2003 using St. Louis County Metro Park funds.
