Coquelin Run
Coquelin Run is a tributary of Rock Creek in Montgomery County, Maryland. It rises in the Town of Chevy Chase, runs for about two miles while draining an area of 1,095 acres (1.71 square miles), and debouches in Rock Creek in unincorporated Chevy Chase. While the stream valley remains largely wooded, it has long been affected by nearby urban and suburban development, and its course has been followed for more than a century by railroads and rail trails. From the 1890s to the 1930s, the stream was dammed to power electric streetcars and to create Chevy Chase Lake, an artificial lake that was the centerpiece of a popular trolley park. Course Coquelin Run rises just east of Elm Street Park in the Town of Chevy Chase, apparently fed by nearby springs or groundwater. It flows for several hundred yards through the back yards of properties along the north and west sides of Elm Street and Oakridge Lane. Several storm sewers carry water into the stream from nearby Bethesda, part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chevy Chase, Maryland
Chevy Chase () is the name of both a town and an unincorporated census-designated place ( Chevy Chase (CDP), Maryland) that straddle the northwest border of Washington, D.C. and Montgomery County, Maryland, United States. Several settlements in the same area of Montgomery County and one neighborhood of Washington include ''Chevy Chase'' in their names. These villages, the town, and the CDP share a common history and together form a larger community colloquially referred to as Chevy Chase. Primarily a residential suburb, Chevy Chase adjoins Friendship Heights, a popular shopping district. It is the home of the Chevy Chase Club and Columbia Country Club, private clubs whose members include many prominent politicians and Washingtonians. Chevy Chase was noted as "the most educated town in America" in a study conducted by the Stanford Graduate School of Education, with 93.5 percent of adult residents having at least a bachelor's degree. The name ''Chevy Chase'' is derived from ''Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stream Restoration
Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development. Stream restoration approaches can be divided into two broad categories: form-based restoration, which relies on physical interventions in a stream to improve its conditions; and process-based restoration, which advocates the restoration of hydrological and geomorphological processes (such as sediment transport or connectivity between the channel and the floodplain) to ensure a stream's resilience and ecological health. Form-based restoration techniques include deflectors; cross-vanes; weirs, step-pools and other grade-control structures; engineered log jams; bank stabilization methods and other channel-reconfiguration efforts. These induce immediate change in a stream, but sometimes fail to achieve the desired effects if degrad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Line (Maryland)
The Purple Line is a light rail line being built to link several Maryland suburbs of Washington, D.C.: Bethesda, Silver Spring, College Park, and New Carrollton. Slated to open in 2026, the line will also enable riders to move between the Maryland branches of the Red, Green, Yellow, and Orange lines of the Washington Metro without riding into central Washington, and between all three lines of the MARC commuter rail system. The project is administered by the Maryland Transit Administration (MTA), an agency of the Maryland Department of Transportation (MDOT), and not the Washington Metropolitan Area Transit Authority (WMATA), which operates Metro. Throughout its decades-long planning process, the project was dogged by resistance, particularly from residents of the upscale community of Chevy Chase. From 2003 to 2006, Maryland Governor Robert Ehrlich changed the proposed mode of transportation from light rail to bus rapid transit. Legal attempts to thwart the line continued even ...

Right-of-way (transportation)
A right-of-way (ROW) is a right to make a way over a piece of land, usually to and from another piece of land. A right of way is a type of easement granted or reserved over the land for transportation purposes, such as a highway, public footpath, rail transport, canal, as well as electrical transmission lines, oil and gas pipelines. In the case of an easement, it may revert to its original owners if the facility is abandoned. This American English term is also used to denote the land itself. A right of way is granted or reserved over the land for transportation purposes, usually for private access to private land and, historically for a highway, public footpath, rail transport, canal, as well as electrical transmission lines, oil and gas pipelines.Henry Campbell Black: ''Right-of-way.''

COLUMBIA COUNTRY CLUB
The Columbia Country Club, located in Chevy Chase, Maryland, is the successor of the Columbia Golf Club, which was organized on September 29, 1898 by nine men. Originally there were twenty members. The golf course, which opened in 1911, was designed by Herbert Barker. The first location of the Club was on the east side of Brightwood Avenue, afterwards known as Georgia Avenue, in the neighborhood of Schuetzen Park. Through its history, the club has counted among its members two Five Star Generals, Omar Bradley and Hap Arnold, along with countless politicians (most notably Barack Obama), journalists, CEOs and lobbyists. History The present site on Connecticut Avenue was purchased in 1909 from the Chevy Chase Land Company. The certificate of incorporation is dated August 25, 1909. The design of Frederick B.

Chevy Chase Lake
Chevy Chase Lake was a trolley park in southern Montgomery County, Maryland, that operated from 1894 until about 1936. It was created by the The Chevy Chase Land Company, Chevy Chase Land Company, which sought to draw residents of Washington, D.C., to its nascent suburb of Chevy Chase, Maryland, Chevy Chase. Its eponymous lake was formed by the 1892 damming of Coquelin Run, a tributary of Rock Creek (Potomac River tributary), Rock Creek. The lake gave its name to the neighborhood that grew up near it in Chevy Chase (CDP), Maryland, unincorporated Chevy Chase. The lake itself provided water for the coal-fired steam turbines that powered the electric streetcars of the Rock Creek Railway, the trolley line built by the Chevy Chase Land Company to connect residents of its new suburb to Washington, D.C. The railway's terminal complex, some 1.7 miles due north of the Maryland-D.C. border, sat just north of the park. It included the power house with its tall chimney, a car barn, a turnaro ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Marylan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
