O John Clark Restricted Landing Area

The airport was closed due to land acquisition and development. The site was purchased to build the permanent Grayslake campus for the College of Lake County, which began construction in the late 1960s. This is a common reason for the closure of small, private airfields located in areas of expanding suburban development.

The site of the former airport is now the central part of the College of Lake County's Grayslake Campus. The coordinates point directly to an area now occupied by campus buildings (such as the Library/Learning Resource Center), parking lots, and landscaped grounds. There are no remaining physical traces of the airstrip.

O John Clark Restricted Landing Area was a privately owned and operated airfield. The 'Restricted Landing Area' (RLA) designation indicates it was not open for public use and was likely a simple grass strip serving the personal, business, or recreational aviation needs of its owner, O. John Clark. Its operations would have consisted of light, single-engine general aviation aircraft. The airfield's significance is primarily local, representing one of the many private airstrips that were common in the rural and semi-rural landscape of the Chicago metropolitan area before being displaced by post-war suburban growth.

None. The land is fully and permanently developed as a major public educational institution. There are no plans, prospects, or physical possibilities for the airport to ever reopen at this location.
