The Cameron Run Watershed (CRW) is a highly urbanized, 44 square-mile watershed located in Northern Virginia. "The region is completely urbanized with nearly 95 percent of the watershed developed with mixed residential and commercial use". Seventy-five percent of the watershed lies in Fairfax County, and the rest lies in Arlington County and the cities of Falls Church and Alexandria, Virginia, Alexandria. In addition to several streams (called “runs”), there are two lakes—Lake Barcroft (137 acres) and Fairview Lake (15 acres)—and four ponds. There are eight sub-watersheds within the CRW. The western part of the CRW lies within the Piedmont (United States), Piedmont; the southeastern part in the Coastal Plain. Tributaries Holmes Run is the primary headwater stream of the CRW. In addition to Holmes Run, the other tributaries to the CRW are: Tripps Run, Backlick Run, Indian Run, and Pike Branch, which all join Cameron Run. Hunting Creek joins Cameron Run right before empty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Huntington, Virginia
Huntington is a census-designated place (CDP) in Fairfax County, Virginia, United States. The population was 11,267 at the 2010 census. It is located next to the southern border of the city of Alexandria and is part of the Washington metropolitan area. Its main component is the namesake Huntington subdivision, a late-1940s neighborhood of mainly duplex homes. In June 2006, the lower-lying northern section was ravaged by floods due to a torrential rainstorm that sent adjoining Cameron Run over its banks. Nevertheless, it remains popular with first-time home buyers due largely to its proximity to the Huntington Metro station, the southern terminus of Metrorail's Yellow Line. There are also several high-rise apartment and condominium complexes on and near U.S. Route 1 where much of the CDP's population resides. The area is included in ZIP code 22303 and has an Alexandria mailing address, although it is outside the city limits. Geography Huntington is located in southeastern Fairf ...

Capital Beltway
The Capital Beltway is a Interstate Highway in the Washington metropolitan area that surrounds Washington, D.C., the capital of the United States, and its inner suburbs in adjacent Maryland and Virginia. It is the basis of the phrase "inside the Beltway", used when referring to issues dealing with U.S. federal government and politics. The highway is signed as Interstate 495 (I-495) for its entire length, and its southern and eastern half concurrency (road), runs concurrently with Interstate 95, I-95. This loop road, circumferential roadway is located not only in the states of Maryland and Virginia, but also crosses briefly (for about ) through the District of Columbia, near the western end of the Woodrow Wilson Bridge over the Potomac River.

Hurricane Eloise
Hurricane Eloise was the most destructive tropical cyclone of the 1975 Atlantic hurricane season. The fifth tropical storm, fourth hurricane, and second major hurricane of the season, Eloise formed as a tropical depression on September 13 to the east of the Virgin Islands. The depression tracked westward and intensified into a tropical storm while passing to the north of Puerto Rico. Eloise briefly attained hurricane intensity soon thereafter, but weakened back to a tropical storm upon making landfall over Hispaniola. A weak and disorganized cyclone, Eloise emerged into open waters of the northern Caribbean Sea; upon striking the northern Yucatan Peninsula, it turned north and began to re-intensify. In the Gulf of Mexico, the cyclone quickly matured and became a Category 3 hurricane on September 23. Eloise made landfall along the Florida Panhandle west of Panama City before moving inland across Alabama and dissipating on September 24. The storm produced torrential rainfall thr ...

Hurricane Agnes
Hurricane Agnes in 1972 was the costliest hurricane to hit the United States at the time, causing an estimated $2.1 billion in damage. The hurricane's death toll was 128. The effects of Agnes were widespread, from the Caribbean to Canada, with much of the east coast of the United States affected. Damage was heaviest in Pennsylvania, where Agnes was the state's wettest tropical cyclone. Due to the significant effects, the name ''Agnes'' was retired in the spring of 1973. Agnes was the second tropical cyclone and first named storm of the 1972 Atlantic hurricane season. It developed as a tropical depression on June 14 from the interaction of a polar front and an upper trough over the Yucatán Peninsula. The storm emerged into the western Caribbean Sea on June 15, and strengthened into Tropical Storm Agnes the next day. Thereafter, Agnes slowly curved northward and passed just west of Cuba on June 17. Early on June 18, the storm intensified enough to be u ...

Lake Barcroft, Virginia
Lake Barcroft is a census-designated place (CDP) in Fairfax County, Virginia, United States. The population was 9,558 at the 2010 census. It is also the name of the privately owned lake—part of the Cameron Run Watershed—around which this population is located. The lake is named for Dr. John W. Barcroft, who owned and operated a mill on Holmes Run during the mid-19th century. History In 1913, the Alexandria Water Company began construction of the Lake Barcroft Dam on Holmes Run to create a drinking water reservoir for the city of Alexandria. Construction of the dam was completed in 1915, putting a 620 million-gallon reservoir into service. In 1942, the company installed 24 gates at the top of the dam to raise the spillway elevation five feet, increasing the reservoir size to 800 million gallons. In 1949, the City of Alexandria began to draw its drinking water from the Occoquan Reservoir. A year later, Colonel Joseph Barger and Associates purchased the reservoir, dam, an ...

Urbanization
Urbanization (or urbanisation) refers to the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized. That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. Notably, the United Nations has also recently projected that nearly all gl ...

NEPA
The National Environmental Policy Act (NEPA) is a United States environmental law that promotes the enhancement of the environment and established the President's Council on Environmental Quality (CEQ). The law was enacted on January 1, 1970.United States. National Environmental Policy Act of 1969. , Approved January 1, 1970. ''et seq.'' To date, more than 100 nations around the world have enacted national environmental policies modeled after NEPA. Prior to NEPA, Federal agencies were mission oriented. An example of mission orientation was to select highway routes as the shortest route between two points. NEPA was necessary to require Federal agencies to evaluate the environmental effects of their actions. NEPA's most significant outcome was the requirement that all executive Federal agencies prepare environmental assessments (EAs) and environmental impact statements (EISs). These reports state the potential environmental effects of proposed Federal agency actions. Further, U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wetlands
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
