Are there any plans with Sapperton park?
Not that I know of. The playing fields are well used, the spray park and playgrounds appear to operate, if a little long-in-tooth. There was talk in the 2008 Parks Comprehensive Plan of replacing the field with artificial turf and replacing the lights, but that appears to have not taken place (while an artificial-turf field was added to Queens Park).
With the Brewery District development, the expansion of RCH, and (likely) subsequent increased business and residential density along East Columbia, one of the City’s most historic parks will definitely be seeing more use and more demands on it. I presume you are a neighbor, so I guess I’ll throw this question back at you: What would you like to see at Sapperton Park?
