I've changed it from park to grass landuse in this chageset: https://www.openstreetmap.org/changeset/112635331
I've tried refining a bit the tagging around it, but the access restrictions are unclear for me. It doesn't seem there are restrictions to the general public on the Goodwin St side, but someone would need to do a proper survey to figure out if any part of it is actually fenced off or signed for private use.
