...beneficial as it has been to the field and the Corktown neighborhood that surrounds it, the NFGC's grass-roots urban renewal project was (and remains) technically illegal, since Navin Field is on city-owned land. The group's efforts have also constituted something of a collective raised middle-finger to the Detroit Economic Growth Corporation, the local development agency that oversaw the demolition of Tiger Stadium, and which has since entertained several redevelopment proposals for the site (Condos! Office space! Big-box retail! A warehouse for parade floats!) that thankfully have yet to come to fruition.
