According to the park district site, Warren Park, 6601 N. Western Ave., is on the site of the former golf club grounds:
Warren Park was created in the 1970s, born of both conflict and cooperation. The controversy began in 1965 when real estate developers offered to purchase the 94-acre private Edgewater Golf Club for $7.6 million from its members. Soon after the community learned that the buyers wanted to build high-rise apartments and a large shopping center on the site, a coalition of local groups known as the Allied North Side Community Organizations launched a major campaign to save the land as open space. Despite the strong community objection, however, the City re-zoned the site in 1968 to allow development to move forward.Original badge available (at time of writing) here: Edgewater Golf Club
When the city failed to support the park scheme, the commuity groups solicited the support of the State Government. In 1969, Governor Ogilvie signed a bill to make the private golf course into a state park. The governor announced that this would be "the first major state park in Illinois created in an urban area. By bringing a park to the people, instead of requiring them to go to a distant park, we shall mark an historic turning point in the battle to preserve open lands."
