Historic Bagley Park is a community park and falls under this definition:

Community parks serve a slightly broader area/population than neighborhood parks. The focus is more on meeting community-based recreational and social needs, as well as preserving unique landscapes and open spaces. The key being preserving unique landscapes and open spaces We vote for NO PARKING in Lower Bagley Park Nature Preserve.

This small greenspace serves over 40,000 people and three direct communities within a 10 minute walk of the park once it becomes a parking lot it is gone forever!
