Recreation ground is definitely not right on this landuse feature (https://www.openstreetmap.org/relation/169042008). Since Perico Preserve (https://www.openstreetmap.org/way/506440833) is already mapped, I am not sure what the landuse=recreation_ground one should be tagged as. I lean toward deleting it. Saying that should be enough to get someone with a better idea to chime in :-)
