West Potomac Park is a U.S. national park in Washington, D.C., adjacent to the National Mall. It includes the parkland that extends south of the Lincoln Memorial Reflecting Pool, from the Lincoln Memorial to the grounds of the Washington Monument. The park is the site of many national landmarks, including the Korean War Veterans Memorial, Jefferson Memorial, Franklin Delano Roosevelt Memorial, George Mason Memorial, Martin Luther King, Jr. National Memorial and the surrounding land on the shore of the Tidal Basin, an artificial inlet of the Potomac River created in the 19th century that links the Potomac with the northern end of the Washington Channel. West Potomac Park is administered by the National Park Service.Creation of the parkAlmost none of the National Mall west of the Washington Monument grounds and below Constitution Avenue NW existed prior to 1882. After terrible flooding inundated much of downtown Washington, D.C., in 1881, Congress ordered the Army Corps of Engineers to dredge a deep channel in the Potomac and use the material to fill in the Potomac (creating the current banks of the river) and raise much of the land near the White House and along Pennsylvania Avenue NW by nearly. This "reclaimed land" — which included West Potomac Park, East Potomac Park, the Tidal Basin — was largely complete by 1890, and designated Potomac Park by Congress in 1897. Congress first appropriated money for the beautification of the reclaimed land in 1902, which led to the planting of sod, bushes, and trees; grading and paving of sidewalks, bridle paths, and driveways; and the installation of water, drainage, and sewage pipes.
