“In order to hopefully avoid litigation to ensure equal treatment, Edgewood is consenting to the city’s invitation to terminate the voluntary Master Plan before it automatically expires,” said Matthew Lee, an attorney representing Edgewood.

Edgewood can appeal the board’s ruling to circuit court. Lee said in an email that Edgewood has "has not relinquished any of its rights" to appeal the decision.

When Edgewood created its Master Plan in 2014, it said the field was used for team practices and physical education, and did not name athletic competitions as a proposed use.

This spring, after Edgewood hosted soccer, track-and-field and lacrosse contests, the city sent out notices of violations that the school appealed. The city argued that Edgewood could only use its field for games if it received Plan Commission approval and amended its master plan.
