Install four regulatory signs in the Yosemite Falls bus parking area to reserve existing oversize vehicle parking spaces for buses that are greater than 30 feet in length. These signs will provide messages such as "Buses Only," "No Parking Behind This Sign," and "Do Not Enter." The bus parking area is not presently marked with traffic control or parking management messages, and is being used by daily visitor vehicles, leaving no parking spaces for public transportation or authorized commercial tour buses.
