Manhattan (), known regionally as the City, is the most densely populated and geographically smallest of the five boroughs of New York City. The borough is also coextensive with New York County, one of the original counties of the U.S. state of New York. Located near the southern tip of New York State, Manhattan is based in the Eastern Time Zone and constitutes both the geographical and demographic center of the Northeast megalopolis and the urban core of the New York metropolitan area, the largest metropolitan area in the world by urban landmass.

Bankruptcy Of Lehman Brothers
The bankruptcy of Lehman Brothers on September 15, 2008, was the climax of the subprime mortgage crisis. After the financial services firm was notified of a pending credit downgrade due to its heavy position in subprime mortgages, the Federal Reserve summoned several banks to negotiate financing for its reorganization. These discussions failed, and Lehman filed a Chapter 11 petition that remains the largest bankruptcy filing in U.S. history, involving more than in assets. The bankruptcy triggered a 4.5% one-day drop in the Dow Jones Industrial Average, then the largest decline since the September 11, 2001, attacks. It signaled a limit to the government's ability to manage the crisis and prompted a general financial panic. Money market mutual funds, a key source of credit, saw mass withdrawal demands to avoid losses, and the interbank lending market tightened, threatening banks with imminent failure. The government and the Federal Reserve system responded with several emergency ...

Shoring
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. ''Shoring'' comes from ''shore'', a timber or metal prop. Shoring may be vertical, angled, or horizontal. Methods Buildings Raking shores In this method, inclined members called rakers are used to give temporary lateral support to an unsafe wall. One or more timbers slope between the face of the structure to be supported and the ground. The most effective support is given if the raker meets the wall at an angle of 60 to 70 degrees. A wall-plate is typically used to increase the area of support. Foundations Shoring is commonly used when installing the foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed. Commonly used shoring equipment includes post shores, shoring beams, and timber jacks ...

Air Rights
Air rights are the property interest in the "space" above the earth's surface. Generally speaking, owning, or renting, land or a building includes the right to use and build in the space above the land without interference by others. This legal concept is encoded in the Latin phrase ''Cuius est solum, eius est usque ad coelum et ad inferos'' ("''Whoever owns the soil, it is theirs up to Heaven and down to Hell''."), which appears in medieval Roman law and is credited to 13th-century glossator Accursius; it was notably popularized in common law in '' Commentaries on the Laws of England'' (1766) by William Blackstone; see origins of phrase for details. Air travel Property rights defined by points on the ground once extended indefinitely upward. This notion remained unchallenged before air travel became popular in the early 20th century. To promote air transport, legislators established a public easement for transit at high altitudes, regardless of real estate ownership. New ...

Grandfather Clause
A grandfather clause, also known as grandfather policy, grandfathering, or grandfathered in, is a provision in which an old rule continues to apply to some existing situations while a new rule will apply to all future cases. Those exempt from the new rule are said to have grandfather rights or acquired rights, or to have been grandfathered in. Frequently, the exemption is limited, as it may extend for a set time, or it may be lost under certain circumstances; for example, a grandfathered power plant might be exempt from new, more restrictive pollution laws, but the exception may be revoked and the new rules would apply if the plant were expanded. Often, such a provision is used as a compromise or out of practicality, to allow new rules to be enacted without upsetting a well-established logistical or political situation. This extends the idea of a rule not being retroactively applied. Origin Southern United States The term originated in late nineteenth-century legislation and ...

Floor Area Ratio
Floor area ratio (FAR) is the ratio of a building's total floor area (gross floor area) to the size of the piece of land upon which it is built. It is often used as one of the regulations in city planning along with the building-to-land ratio. The terms can also refer to limits imposed on such a ratio through zoning. Written as a formula, FAR = . Lower maximum-allowed floor area ratios are linked to lower land values and lower housing density. Terminology Floor Area ratio is sometimes called floor space ratio (FSR), floor space index (FSI), site ratio or plot ratio. The difference between FAR and FSI is that the first is a ratio, while the latter is an index. Index numbers are values expressed as a percentage of a single base figure. Thus an FAR of 1.5 is translated as an FSI of 150%. Regional variation The terms most commonly used for this measurement vary from one country or region to the next. In Australia ''floor space ratio'' (FSR) is used in New South Wales and ''plot ...

1961 Zoning Resolution
The 1916 Zoning Resolution in New York City was the first citywide zoning code in the United States. The zoning resolution reflected both borough and local interests, and was proposed after the Equitable Building was erected in Lower Manhattan in 1915. The resolution was a measure adopted primarily to stop massive buildings from preventing light and air from reaching the streets below, and established limits in building massing at certain heights, usually interpreted as a series of setbacks and, while not imposing height limits, restricted towers to 25% of the lot size. The chief authors of this resolution were George McAneny and Edward M. Bassett. Impact The 1916 Zoning Resolution had a major impact on urban development in both the United States and internationally. Architectural delineator Hugh Ferriss popularized these new regulations in 1922 through a series of massing studies, clearly depicting the possible forms and how to maximize building volumes. "By the end of ...

Central Business District
A central business district (CBD) is the commercial and business centre of a city. It contains commercial space and offices, and in larger cities will often be described as a financial district. Geographically, it often coincides with the "city centre" or "downtown". However, these concepts are not necessarily synonymous: many cities have a central ''business'' district located away from its commercial and or cultural centre and or downtown/city centre, and there may be multiple CBDs within a single urban area. The CBD will often be characterised by a high degree of accessibility as well as a large variety and concentration of specialised goods and services compared to other parts of the city. For instance, Midtown Manhattan, New York City, is the largest central business district in the city and in the United States. London's city centre is usually regarded as encompassing the historic City of London and the medieval City of Westminster, while the City of London and the transform ...
