Information about Geography Of New York City

The geography of New York City is characterized by its coastal position at the meeting of the Hudson River and the Atlantic Ocean in a naturally sheltered harbor. The city's geography, with its scarce available land surrounded mostly by water, is a factor in making New York the city with the highest population density in the United States. Environmental issues are chiefly concerned with managing this density, which is also a factor in making New York among the most energy efficient and least automobile-dependent cities in the United States. The city's climate is temperate.

Geography

New York City is located on the coast of the Northeastern United States at the mouth of the Hudson River in southeastern New York state. The New York Harbor, with its deep waters and sheltered bays, helped the city grow in significance as a trading city. Much of New York is built on the three islands of Manhattan, Staten Island, and western Long Island, making land scarce and encouraging a high population density.

The Hudson River flows from the Hudson Valley into New York Bay, becoming a tidal estuary that separates the city from New Jersey. The East River, actually a tidal strait, flows from Long Island Sound and separates the Bronx and Manhattan from Long Island. The Harlem River, another tidal strait between the East and Hudson Rivers, separates Manhattan from the Bronx.

The city's land has been altered considerably by human intervention, with substantial land reclamation along the waterfronts since Dutch colonial times. Reclamation is most notable in Lower Manhattan with modern developments like Battery Park City. Much of the natural variations in topography have been evened out, particularly in Manhattan.^[1]

The city's land area is 321 mi² (831.4 km²).^[2] The highest natural point in the city is Todt Hill on Staten Island, which at 409.8 ft (124.9 m) above sea level is the highest hill on the Eastern Seaboard south of Maine. The summit of the ridge is largely covered in woodlands as part of the Staten Island Greenbelt.

Boroughs

Main articles: The five boroughs and Neighborhoods of New York City

New York City comprises five boroughs, an unusual form of government used to administer the five constituent counties that make up the city. Throughout the boroughs there are hundreds of distinct , many with a definable history and character all their own. If the boroughs were each independent cities, four of the boroughs (Brooklyn, Queens, Manhattan, and the Bronx) would be among the ten most populous cities in the United States.

• The Bronx (Bronx County, pop. 1,364,566)<ref name="census" /> is New York City's northernmost borough. It is the birthplace of rap and hip hop culture,^[3] the site of Yankee Stadium and home to the largest cooperatively owned housing complex in the United States, Co-op City.^[4] Except for a small piece of Manhattan known as Marble Hill, the Bronx is the only section of the city that is part of the United States mainland.
• Brooklyn (Kings County, pop. 2,511,408)<ref name="census" /> is the city's most populous borough and was an independent city until 1898. Brooklyn is known for its cultural diversity, an independent art scene, distinct neighborhoods and a unique architectural heritage. The borough also features a long beachfront and Coney Island, famous as one of the earliest amusement grounds in the country.
• Manhattan (New York County, pop. 1,606,275)^[5] is the most densely populated borough and home to most of the city's skyscrapers. The borough contains the major business centers of the city and many cultural attractions. Manhattan is loosely divided into downtown, midtown, and uptown regions.
• Queens (Queens County, pop. 2,256,576)<ref name="census" /> is geographically the largest borough and the most ethnically diverse county in the United States.^[6] Historically a collection of small towns and villages founded by the Dutch, the borough today is mainly residential and middle class. It is the only large county in the United States where the median income among African-American households, about $52,000 a year, has surpassed that of Caucassian households.^[7] Queens is the site of Shea Stadium, the home of the New York Mets, and annually hosts the US Tennis Open.
• Staten Island (Richmond County, pop. 475,014)<ref name="census" /> is the most suburban in character of the five boroughs. It is connected to Brooklyn by the Verrazano-Narrows Bridge and to Manhattan by the free Staten Island Ferry. Until 2001 the borough was home to the Fresh Kills Landfill, formerly the largest landfill in the world, which is now being reconstructed as one of the largest urban parks in the United States.

Climate

New York City has a humid continental climate (Koppen climate classification Dfa) with hot, humid summers and cool to cold winters, vastly affected by its proximity to the Atlantic Ocean. New York City's climate patterns are affected by the Atlantic Multidecadal Oscillation, a 70-year-long warming and cooling cycle in the Atlantic that influences the frequency and severity of hurricanes and coastal storms.^[8]

• Winters are typically cold. Temperatures below 0 °F only occur about once per decade on average, but temperatures in the 10s and 20s (down to -10 °C) are quite common at the height of winter. New York winters sometimes feature snowstorms that can paralyze the city with over a foot of snow. However, variation in the climate also occasionally renders winter mild and almost snowless (such as in 1997-98).
• Springs are mild, averaging in the 50s °F (10 to 15 °C) in late March to the lower 80s °F (25-30 °C) in early June. The weather is unpredictable and brings relatively cool summers (such as in 1992) as an occasional surprise, and huge snowstorms arriving as late as the second week in April (significant snow after mid-March is fairly rare though). Thunderstorms are common in spring.
• Summers in New York are hot and humid, with temperatures commonly exceeding 90 °F (32 °C), although high temperatures above 100 °F (38 °C) are about as rare as subzero (F) lows in winter. Humidity levels are usually quite high in July and August. Thunderstorms are common in summer, although severe weather is more common west of the city in New Jersey because the city's proximity to the ocean usually kills severe thunderstorms before they hit the city. Hurricanes are considered to be a major threat to the area (and especially the Long Island suburbs). While relatively infrequent compared to areas south and east, a direct hit could cause large loss of life and enormous property damage in damage due to the high population in coastal areas.
• Autumns are comfortable in New York and similar to spring in temperature. However, the weather is notably unpredictable and travelers are advised to check forecasts and bring several layers of clothing in late fall and in the early spring months (e.g., November, March, April) as temperatures do fluctuate quickly at these times of year.
• Temperature records have been set as high as 106 °F (41 °C) on July 9, 1936 (in Central Park, LaGuardia Airport recorded a 107 °F (42 °C) temperature on July 3, 1966) and as low as -15 °F (-26 °C) on February 9, 1934. These temperatures are not common and have not been matched or surpassed in more than seven decades. Most recently, temperatures have hit 100 degrees as recently as July 2005 and 103 degrees in August 2006 (both at LaGuardia Airport; Central Park last recorded a temperature at or over 100 °F in August 2001), and dropped to just 1 above zero as recently as January 2004 (the last sub-zero reading was in January 1994). New York can have excessive days of rain or long stretches of dry weather.

Environmental issues

Main articles: Environmental issues in New York City and Assessing the Impact of Interannual Climate Variability on New York City's Reservoir System

New York City plays an important role in the green policy agenda because of its size. Environmental groups make large efforts to help shape legislation in New York because they see the strategy as an efficient way to influence national programs. New York City's economy is larger than Switzerland's, a size that means the city has potential to set new defacto standards. Manufacturers are also attuned to the latest trends and needs in the city because the market is simply too big to ignore.

Although cities like San Francisco or Portland, Oregon are most commonly associated with urban environmentalism in the United States, New York City's unique urban footprint and extensive transportation systems make it more sustainable than most American cities. The environmental organization SustainLane ranked New York highest of all U.S. cities with more than 1 million residents in its 2005 US City Rankings, a detailed report on city quality of life combined with indicators of sustainability programs, policies and performance.^[9] The organization cited New York's land use, density, transportation systems, innovative watershed management, and extensive local food and agriculture resources that include 750 community gardens and 64 farmers markets as some of the city's strongest environmental assets.
