WTregaron Estate, formerly known as The Causeway, is a country house and estate located in the Cleveland Park neighborhood of Northwest, Washington, D.C.. The estate, built in 1912, was designed by architect Charles Adams Platt and landscape architect Ellen Biddle Shipman. The original owners, Alice and James Parmelee, lived at the estate from the time of its construction until 1940. From 1942 to 1958, it was occupied by Joseph E. Davies, who had served as United States ambassador to several countries, and his second wife, Post Cereal Company heiress Marjorie Merriweather Post. Today the estate is occupied by a campus of the Washington International School and the Tregaron Conservancy.
WThe Chesapeake Beach Rail Trail is a set of short trails along the original Chesapeake Beach Railway route from Washington, D.C. to Chesapeake Beach, Maryland. The Maryland-National Capital Park and Planning Commission (M-NCPPC) acquired portions of the corridor through the subdivision process. Some sections have already been built. Plans call for future sections to be built as available until this corridor serves as the spine for a number of greenway branches.
WThe Georgetown street renaming occurred as a result of an 1895 act of the United States Congress that ended even the nominal independence of Georgetown from Washington, D.C. The Act required, inter alia, that the street names in Georgetown be changed to conform to the street-naming system in use in the Northwest quadrant of Washington, D.C. However, the old street names were shown on maps as late as 1899.
WHains Point is located at the southern tip of East Potomac Park between the main branch of the Potomac River and the Washington Channel in southwest Washington, D.C.

WMurder Bay was a disreputable slum in Washington D.C. roughly bounded by Constitution Avenue NW, Pennsylvania Avenue NW, and 15th Street NW. The area was a center of crime through the early 20th century, with an extensive criminal underclass and prostitution occurring in several brothels and hotels in the area. The area was completely rebuilt during the construction of the Federal Triangle project in the late 1920s and 1930s.
WWashington, D.C., is administratively divided into four geographical quadrants of unequal size, each delineated by their ordinal directions from the medallion located in the Crypt under the Rotunda of the Capitol. Street and number addressing, centered on the Capitol, radiates out into each of the quadrants, producing a number of intersections of identically named cross-streets in each quadrant. Originally, the District of Columbia was a near-perfect square. However, even then the Capitol was never located at the geographic center of the territory. As a result, the quadrants are of greatly varying size. Northwest is quite large, encompassing over a third of the city's geographical area, while Southwest is little more than a neighborhood and military base.
WThe Washington City Canal operated from 1815 until the mid-1850s in Washington, D.C. The canal connected the Anacostia River, termed the "Eastern Branch" at that time, to Tiber Creek, the Potomac River, and later the Chesapeake and Ohio Canal (C&O). The canal became disused during the late 19th century and the city government covered over or filled in various sections in 1871.
