The Capitol Grounds and Arboretum jurisdiction is responsible for both the day-to-day maintenance of the U.S. Capitol grounds and preservation of a significant historic landscape and accredited arboretum designed by Frederick Law Olmsted. 

The U.S. Capitol grounds are comprised of approximately 286 acres, including the U.S. Capitol, Senate and House Office Buildings, the Capitol Power Plant and Union Square. This area includes lawns, parks, historic, memorial and commemorative trees; horticultural display beds; supporting decorative features such as statuary; and historic fountains and water features providing a safe and awe-inspiring setting for the U.S. Capitol.
