Bellevue (Washington, D.C.)

Fort Greble was an American Civil War-era Union fortification constructed as part of the defenses of Washington, D.C. during that war. Named for First Lieutenant John Trout Greble, the first West Point graduate killed in the U.S. Civil War, it protected the junction of the Anacostia and Potomac rivers, and from its position on a bluff in the Congress Heights, precluded any bombardment of the Washington Navy Yard and southeastern portions of the city. It was supported by Fort Carroll to the northeast and Fort Foote to the south. It never fired a shot during the war, and after a brief stint as a U.S. Army Signal Corps training facility, was abandoned and the land returned to its natural state. As of July 2007, the site of the fort is a community park.

Blue Plains Advanced Wastewater Treatment Plant, located at 5000 Overlook Ave SW, Washington, DC 20032, is the largest advanced wastewater treatment plant in the world. The facility is operated by the District of Columbia Water and Sewer Authority (DC Water). The plant opened in 1937 as a primary treatment facility, and advanced treatment capacity was added in the 1970s and 1980s. The effluent that leaves Blue Plains is discharged to the Potomac River and meets some of the most stringent permit limits in the United States.

The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research.As of 2016, NRL was a Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

United States Coast Guard Station Washington is a United States Coast Guard station located on Joint Base Anacostia-Bolling in Washington, D.C. The station was commissioned on September 23, 2003.

Shepherd Parkway is part of the Civil War Defenses of Washington. It includes two forts (Forts Greble and Carroll), of which some remains still exist. The parkway runs along the high ground opposite the Anacostia Freeway (Interstate 295) from Joint Base Anacostia–Bolling in the District of Columbia. Shepherd Parkway is bordered on the north by St. Elizabeths Campus and the District of Columbia neighborhoods of Congress Heights and Bellevue and on the south (near Oxon Run) by Bald Eagle Hill.

Bellevue/William O. Lockridge Neighborhood Library is part of the District of Columbia Public Library (DCPL) System. It was originally opened to the public in 1959. It was renovated with a design by British architect David Adjaye and named after activist William O'Neal Lockridge.

Blue Plains is a locale in the southwest quadrant of Washington, D.C. The area gives its name to the Blue Plains Advanced Wastewater Treatment Plant.

Oxon Run is a tributary stream of Oxon Creek and the Potomac River in Prince George's County, Maryland, and Washington, D.C. In early maps, the stream is usually called "Oxen Run" and in 1892 the U.S. Geological Survey still labelled the stream as "Oxen Run" on its maps. Late in that year they changed the spelling they used, and others have followed suit, though it's unclear what led to the spelling change. Government officials and mapmakers often don't make a distinction between Oxon Creek and Oxon Run, instead treating Oxon Creek as a continuation of Oxon Run, but USGS still does. USGS first started labeling it as Oxon Creek in 1892.

The National Intelligence University (NIU), formerly known as the Defense Intelligence School, the Defense Intelligence College, the Joint Military Intelligence College, and the National Defense Intelligence College is a federally chartered research university in Bethesda, Maryland. NIU is the United States Intelligence Community's (IC) institution for higher learning in fields of study central to the profession of intelligence and national security. NIU awards undergraduate and graduate degrees, a graduate certificate, and prestigious research fellowships to prepare personnel for senior positions in the IC and the broader national security enterprise. Since 1963, more than 80,000 military and civilian students have attended the university. Formerly located at the Defense Intelligence Agency headquarters in Washington, D.C., NIU's primary campus is now located at Intelligence Community Campus-Bethesda (ICC-B) with four additional locations around the world. National Intelligence University's interdisciplinary programs emphasize education through scholarly and applied research designed to help U.S. intelligence officers better understand the diverse range of geopolitical, strategic, and technological threats and opportunities affecting intelligence and national security. The university is organized into two separate academic units: the College of Strategic Intelligence and the Anthony G. Oettinger School of Science and Technology Intelligence. Combined, the college and school cover a diverse and evolving range of international affairs issues and adversarial threats and capabilities, from cultural and religious conflicts to WMD proliferation, cybersecurity threats, terrorism, transnational crime, and more.Congressionally chartered and publicly funded but with admissions restricted solely to current U.S. Intelligence officers holding a Top Secret/Sensitive Compartmented Information clearance, NIU is a small, non-resident university. Admissions are highly selective, but tuition is paid by the United States Government.

Joint Base Anacostia–Bolling is a 905-acre (366 ha) military installation, located in Southeast, Washington, D.C., established on 1 October 2010 in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of Naval Support Facility Anacostia (NSF) and Bolling Air Force Base (BAFB), which were adjoining, but separate military installations, into a single joint base, one of twelve formed in the country as a result of the law. The base hosts the Defense Intelligence Agency Headquarters amongst its other responsibilities. The only aeronautical facility at the base is a 100-by-100-foot (30 by 30 m) helipad (ICAO: KBOF).

Bolling Air Force Base or Bolling AFB was a United States Air Force base in Washington, D.C. In 2010, it was merged with Naval Support Facility Anacostia to form Joint Base Anacostia–Bolling. From its beginning, the installation has hosted elements of the Army Air Corps (predecessor to today's Air Force) and Navy aviation and support elements.

Oxon Creek is a stream on the Potomac River which feeds a cove that straddles the border between Washington, D.C. and Prince George's County, Maryland just north of Interstate 495 (Capital Beltway) at Woodrow Wilson Bridge. Oxon Creek heads at the confluence of Oxon Run and Barnaby Run, sometimes referred to as Winkle Doodle Run. It starts just inside the boundary of D.C. and then runs 1.5 miles (2.4 km) to the south and west into Maryland to empty into the Potomac at Goose Island (a sand bar often under water) across from the city of Alexandria, Virginia. Before reaching the Potomac, the creek widens to form Oxon Cove which is partially in Maryland and partially in Washington, D.C.. The creek is almost entirely within Oxon Cove National Park, except for the first few feet in D.C. and a portion of the cove on the southside of the Blue Plains Advanced Wastewater Treatment Plant.Two bridges cross the creek. The Anacostia Freeway crosses it on a bridge where it becomes a tidal stream and the Oxon Hill Farm Trail crosses it where it is still narrow. The unusual spelling is either historical or a reference to Oxfordshire, England, though it was usually labelled as Oxen Creek on maps prior to 1898. The distinction between Oxon Creek and Oxon Run is often not recognized and so both are frequently referred to as Oxon Run. USGS first started labeling it as Oxon Creek in 1892.
