Sometime in 2013, there was an earthquake in National City.
In September 2014, there were wildfires that killed eight people.
Project Cadmus tried to capture all aliens in the country, and went to many places including National City.
After Rhea and Lena Luthor built a portal device, Rhea used it to bring thousands of Daxamites over to National City, calling it the "new Daxam". Supergirl was forced to use a device that released lead into the atmosphere, which forced all of the Daxamites to leave.
As both a thank you and reward for having saved both the city and world, the National City committee built a Supergirl statue. At the unveiling there was an attack, but Supergirl was able to stop it before anyone was seriously injured.
Throughout the city, children started getting sick from what appeared to be lead poisoning. The city first thought that the lead poisoning was from the device Lena Luthor had made to force all the Daxamites to leave the city. It was later discovered that Morgan Edge was responsible for the poisoning, as he had poisoned the water of a public pool to frame Lena.

Behind the scenes
- Even though the city was an original creation for the show, it made its first official appearance in the mainstream DC universe in Action Comics vol. 2, #51, after a mention in Batman/Superman #31. It would later serve as the setting for Supergirl as part of the DC Rebirth event, when the new Supergirl comic book series would borrow several elements from the show.
