East Potomac Park is a park located on a man-made island in the Potomac River in Washington, D.C., in the United States. The park lies southwest of the Jefferson Memorial and the 14th Street Bridge, and the Washington Channel lies between the park and the Potomac River. Amenities in East Potomac Park include the East Potomac Park Golf Course, a miniature golf course, a public swimming pool (the East Potomac Park Aquatic Center), tennis courts, and several athletic fields (some configured for baseball and softball, others for soccer, rugby, or American football). The park is a popular spot for fishermen, and cyclists, walkers, inline skaters, and runners heavily use the park's roads and paths. A portion of Ohio Drive SW runs along the perimeter of the park. East Potomac Park is accessible primarily by road via Ohio Drive SW. The DC Circulator National Mall Route, which began service in June 2015, provides the best public transportation option for reaching East Potomac Park. The closest Circulator stop is at East Basin Drive SW south of the Jefferson Memorial, which is within easy walking distance of Ohio Drive SW and the north end of the park. Metrobus does not serve the park, and there is no Washington Metro stop close to the park. The nearest Metro stop is the Smithsonian station at Independence Avenue SW and 12th Street SW, about six blocks away. (Walking from Metro requires accessing the park via Raoul Wallenberg Place SW, Maine Avenue SW, and Ohio Drive SW.) ==Construction== Although the shoreline of the Potomac River in the District of Columbia was likely to have been littered with shoals, sandbars, and marsh flats, no documentation of these was undertaken until 1834. At that time, the United States Army Corps of Topographical Engineers identified extensive tidal flats below Long Bridge (the predecessor structure to the 14th Street Bridge). These varied in size, but the largest was in size at low tide. By 1881, these extended from about the Old Naval Observatory down to Buzzard Point. Near the modern intersection of 17th Street NW and Constitution Avenue NW, the city's sewer system discharged into an extensive tidal flat, known as Kidwell's Meadows. Exposed to the air about half the time, the sewage began decomposing, creating a powerful, rank smell. The southern part of the Pennsylvania Avenue district was flooded many times in the last three decades of the 19th century. Major floods occurred in October 1870 (during which Chain Bridge was destroyed), February 1881, November 1887, and June 1889 (the same storm which caused the Johnstown Flood). Floodwaters were high enough that rowboats were used on the avenue, and horse-drawn streetcars saw water reach the bottom of the trams. After a disastrous flood in 1881, the United States Army Corps of Engineers dredged a deep channel in the Potomac and used 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 . Much of the dredged material was used to build up the existing tidal flats in the Potomac River as well as sandbars which had been created by silting around Long Bridge. Reclamation occurred in three phases: Section 1 (what is now West Potomac Park), section 2 (what is now the area around the Tidal Basin), and section 3 (what is now East Potomac Park). Congress formally designated these areas "Potomac Park" on March 3, 1897. To ensure that the island was not eroded by the river, poplars and willows were planted along edge of the island to stabilize the shoreline. Over the next two decades, most of East Potomac Park lay untouched, and dense thickets of trees and brush grew up on the island. Dredging of the Potomac River continued even after East Potomac Park was considered finished, and additional dredged material was placed on the island in late 1900, 1901, 1902, 1903, 1904, and 1907. Beginning in late 1907, a bridge was built across the Tidal Basin Outlet Channel, carrying the Washington, Alexandria, and Mount Vernon Electric Railway (a streetcar line) over the Washington Channel and the Long Bridge into Virginia. This was completed in June 1908. More dredge material was deposited on the island in 1909, 1911, and 1912. In 1900, the United States Senate established the Senate Park Commission to reconcile competing visions for the development of Washington, D.C., and the parks within it. Better known as the "McMillan Commission" because of its influential chairman, Senator James McMillan, the Commission released a document known as McMillan Plan in 1902. The McMillan Plan called for turning the undeveloped land into a formal park with extensive recreation facilities. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「East Potomac Park」の詳細全文を読む スポンサード リンク
