Information: - The Central Business District (CBD) is a neighborhood of the city of New Orleans, Louisiana, United States. - The 7th Ward is a section of New Orleans, Louisiana. It is geographically the second largest of the 17 Wards of New Orleans, after the 9th Ward. - Bayou St. John is a bayou within the city of New Orleans, Louisiana. The Bayou as a natural feature drained the swampy land of a good portion of what was to become New Orleans, into Lake Pontchartrain. In its natural state, it extended much farther than today; 18th- and early 19th-century maps show it had tributaries or branches (at least seasonally) reaching into what are now the Broadmoor neighborhood, the New Orleans Central Business District just back from St. Charles Avenue above Lee Circle, the Carrollton neighborhood, the Treme neighborhood, and a branch connecting to Bayou Gentilly. - Hurricane Katrina was the costliest natural disaster and one of the five deadliest hurricanes in the history of the United States. The storm is currently ranked as the third most intense United States landfalling tropical cyclone, behind only the 1935 Labor Day hurricane and Hurricane Camille in 1969. Overall, at least 1,245people died in the hurricane and subsequent floods, making it the deadliest United States hurricane since the 1928 Okeechobee hurricane. Total property damage was estimated at $108 billion (2005 USD), roughly four times the damage wrought by Hurricane Andrew in 1992 in the United States. - The London Avenue Canal is a drainage canal in New Orleans, Louisiana, used for pumping rain water into Lake Pontchartrain. The Canal runs through the 7th Ward of New Orleans from the Gentilly area to the Lakefront. It is one of the three main drainage canals responsible for draining rainwater from the main basin of the city of New Orleans. The London Avenue Canal's flood walls built atop earthen levees breached on both sides during Hurricane Katrina in 2005. - In usage in the United States, a bayou (or , from Cajun French) is a body of water typically found in a flat, low-lying area, and can be either an extremely slow-moving stream or river (often with a poorly defined shoreline), or a marshy lake or wetland. The name "bayou" can also refer to a creek whose current reverses daily due to tides and which contains brackish water highly conducive to fish life and plankton. Bayous are commonly found in the Gulf Coast region of the southern United States, notably the Mississippi River Delta, with the states of Louisiana and Texas being famous for them. A bayou is frequently an anabranch or minor braid of a braided channel that is moving much more slowly than the mainstem, often becoming boggy and stagnant. Though fauna varies by region, many bayous are home to crawfish, certain species of shrimp, other shellfish, catfish, frogs, toads, American alligators, American crocodiles, herons, turtles, spoonbills, snakes, leeches, and a myriad of other species. Etymology. The word was first used by the English in Louisiana and is thought to originate from the Choctaw word "bayuk", which means "small stream". The first settlements of Bayou Teche, and other bayous, were by the Creoles, and that is why bayous are associated with Creole culture. - Lake Pontchartrain is a brackish estuary located in southeastern Louisiana in the United States. It covers an area of with an average depth of . Some shipping channels are kept deeper through dredging. It is roughly oval in shape, about from west to east and from south to north. - Filmore is a neighborhood of the city of New Orleans . A subdistrict of the Gentilly District Area , its boundaries as defined by the City Planning Commission are : Robert E. Lee Boulevard to the north , London Avenue Canal to the east , Press Drive , Paris Avenue and Harrison Avenue to the south and Bayou St. John to the west . - Canals and navigations are human-made channels for water conveyance (supply), or to service water transport vehicles. In the vernacular, both are referred to as 'canals', and in most cases, the engineered works will have a series of dams and locks that create areas of low speed current flow. These areas are referred to as" 'slack water levels'," often just called 'levels'. The main difference between them is that a navigation parallels a river and shares part of its waters, its drainage basin and leverages its resources by building dams and locks to increase and lengthen its long stretches of "deep enough" slack water levels while staying in its valley. In contrast, a canal cuts across a drainage divide atop a ridge (however humble), generally requiring an external water source above the highest elevation. Many canals have been built at elevations towering over valleys and others water ways crossing far below. Cities need a lot of fresh water and many canals with sources of water at a higher level can deliver water to a destination where there is a lack of water. The Roman Empire's Aqueducts were such water supply canals. - St. Charles Avenue is a thoroughfare in New Orleans, Louisiana, U.S. and the home of the St. Charles Streetcar Line. It is also famous for the dozens of mansions that adorn the tree-lined boulevard for much of the uptown section of the boulevard. - Lee Circle is a traffic circle with a monument to Confederate General, Robert E. Lee, in New Orleans, Louisiana. It is located on St. Charles Avenue, where it intersects Howard Avenue. Prior to the erection of the monument in 1884, the location was known as Tivoli Circle or Place du Tivoli. Tivoli Circle was an important, central point in the city, as it linked upriver areas with downriver areas. It was a common local meeting point and the site remains a popular place to gather for Mardi Gras parades. With the addition of the Robert E. Lee Monument, it was renamed Lee Circle.
