there are a few parks located in this area under the overpasses here, anyone with knowledge as to the names and boundaries please add

suggest adding relation for the South Bay Harbor Trail as its made up of a variety of pathways...

looks like these bleachers also have building=stadium tags on them, since they are not technically a building rather a part of a building Id suggest removing the building tag from them or changing it to building:part=yes

towers here could be better classified by type, such as communication tower etc. if its known...

confirmation needed but this location is listed as Deer Springs Fire Station in the official CalFire facility map...

looks like there are overlapping buildings on this pier, suggest removing the overlapping building: way/586018556 and moving its tags either to a relation or a node...

library poi details here are pretty sparse... anyone know what this is? if so please add more tags here to update the name...

looks like there are only taxiways tagged here, anyone know where the runways are?

Dont think this is a park rather it may be best classified by its landuse eg scrub, grass etc instead. Suggest removing park tag and replacing with a more proper classification...
