Okay so let's talk inauguration and the associated protest actions that are being planned.
Each time an inauguration day comes around, the National Park Service of course reserves space for such festivities well in advance, to allow for reconditioning/maintenance of the grounds, placement of access fencing, grandstands, portalets, additional trash receptacles etc., and to reserve the route the inauguration will take. It's not uncommon for The Mall, Pennsylvania Avenue, the parks surrounding the White House and the south side of the Capitol Building, as well as some of the monuments near those areas to be included in such plans. It's also not uncommon that not all of the locations are used, and are re-opened to the general public. Lastly, the common timeframe for most of the inaugural activities is a week, with the exception of the immediate vicinity of the stage due to construction and teardown.
The responsibility for planning the inauguration however falls to an Inauguration Committee chosen by the President-elect. They communicate with the NPS about the parade route, organize funding, hire workers for construction of the stage etc. They also communicate with the Capitol Police and Secret Service regarding security.
With that all in mind,
