Not sure on the status of those.
Nice job on the compilation of projects. It's pretty exciting all of the projects that are now in queue.
Here is something I came across that details the height limit restrictions.

Some of you may already know this, but the FAA doesn't actually regulate the building heights around the airport, the city does. That said, the FAA can threaten to shut down the airport if development creates dangerous conditions.
There is a minimum circling height of 800ft for planes over downtown within 2.3 miles of the airport (basically to the tip of Barrio Logan). As such, the city chose a 500ft height limit to provide a buffer. Ironically, the one place where buildings higher than 500ft could go (barrio logan) is zoned to somewhere around 60ft if I recall.
