There are two polygons here, one for Fort DeRussy Beach Park https://www.openstreetmap.org/way/509354370 and one for Fort De Russy https://www.openstreetmap.org/relation/7409047, unclear if there are actually two separate entities here or if there is instead just one entity... but if there is only one then suggest removing the beach park area and keeping the more comprehensive Fort De Russy area. In addition, even though Fort De Russy is open to the public, it is still considered a military facility technically so in addition to the park tag it could also have a military landuse tag...
