The city is apparently planning to give over almost all of Near Southeast's and Southwest's on-street parking to charter buses on Inauguration Day, according to the Post
: "With the exception of some residential areas, all curbside parking will be set aside for buses; streets will be restricted to charter bus, transit bus and official inaugural vehicles, he said. [...] The charter bus restrictions will take effect at 12:01 a.m. Jan. 20. Other vehicles parked on the streets after that will be towed." Here's the map with the parking zones
. I imagine the neighborhood's numerous surface parking lots might be handed to buses as well, though I'm not sure they can get through the gates.
Shoot, I meant to include this, from WTOP
: "The U.S. Coast Guard has proposed closing the Potomac and Anacostia rivers for the 11 days surrounding the inauguration. [...] Boats already docked or anchored in that area before Jan. 14 could stay. The Anacostia River would have the same restrictions from New York Avenue/Route 50 to the the Potomac River. It's likely the the closures will go into effect at 4 a.m. Jan. 14 and last until 10 p.m. Jan. 25."
