Government facility not for public access

I’m trying to remove some portals that the public should not access. It is on a government facility that is not open to the public. I work security there and we have issues with people wondering into non public areas that should not be there. How do I remove them?

You can't get them removed yourself as they don't technically meet standard removal criteria.
You'd need to ask someone in a position of authority (such as the landowner or the senior figure of the department that uses the facility) to contact Niantic using the form linked below, and the person who is filling in the form will likely need to be able to verify that they are indeed a senior figure or landowner. Niantic will then correspond with that person in order to see what action is best to take regarding the wayspots.
