Geography
New York City is located in the
Northeastern United States, in southeastern New York State, approximately halfway between Washington, D.C.
and Boston. The location at the mouth
of the Hudson River, which feeds into a naturally sheltered harbor
and then into the Atlantic Ocean, has 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 Long Island, making land scarce and encouraging a high
population density.
The Hudson River flows through the Hudson Valley into New York Bay. Between New York City and Troy, New York, the river
is an estuary. The Hudson separates the
city from New Jersey. The East River – 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 most of Manhattan
from the Bronx. The Bronx River, which flows through the Bronx and Westchester County, is the
only entirely fresh water river in the city.
The city's land has been altered
substantially by human intervention, with considerable land reclamation along the waterfronts since Dutch colonial times.
Reclamation is most prominent in Lower Manhattan, with developments such as Battery Park City in the 1970s and 1980s. Some of the natural
variations in topography have been evened out, especially in Manhattan.
The city's total area is 468.9 square
miles (1,214 km2). 164.1 square miles (425 km2)
of this are water and 304.8 square miles (789 km2) is land. The highest point in the
city is Todt Hill on Staten Island, which,
at 409.8 feet (124.9 m) above sea level, is the
highest point on the Eastern Seaboard south of Maine. The summit of the ridge
is mostly covered in woodlands as part of the Staten Island Greenbelt.
Climate
Under the Köppen climate
classification New York City has a humid subtropical
climate (Cfa), and using
the 0 °C (32 °F) threshold it is the northernmost major city on the
continent with such categorization.
The area averages 234 days with at
least some sunshine annually, and averages 58% of possible sunshine annually, accumulating 2,400 to
2,800 hours of sunshine per annum.
Winters are cold and damp, and
prevailing wind patterns that blow offshore minimize the moderating effects of
the Atlantic Ocean. Yet the Atlantic and the partial shielding of the Appalachians keep the city warmer in the winter than inland North
American cities located at similar or lesser latitudes such as Pittsburgh, Cincinnati, and Indianapolis. The average
temperature in January, the area's coldest month, is 32.1 °F (0.1 °C).
However temperatures in winter could for a few days be as low as 10 °F (−12 °C) and as high as 50 °F (10 °C). Spring and autumn are
unpredictable, and can range from chilly to warm, although they are usually
mild with low humidity. Summers are typically hot and humid with a July average
of 76.5 °F (24.7 °C).
Nighttime conditions are often exacerbated by the urban heat island phenomenon,
and temperatures exceed 90 °F (32 °C) on
average of 18 days each summer and can exceed 100 °F (38 °C) every
4–6 years.
The city receives 49.7 inches
(1,260 mm) of precipitation annually, which is fairly spread throughout
the year. Average winter snowfall for 1971 to 2000 has been 22.4 inches
(57 cm), but this usually varies considerably from year to year.Hurricanes and tropical storms are rare in the New
York area, but are not unheard of and always have the potential to strike the
area.
Extreme temperatures have ranged from
−15 to 106 °F (-26 to 41 °C), recorded on February 9, 1934 and July
9, 1936, respectively.
Environment
Mass transit use in New York City is
the highest in the United States, and gasoline consumption in the city is the
same rate as the national average in the 1920s. The
city's high level of mass transit use saved 1.8 billion gallons of oil in
2006; New York City saves half of all the oil saved by transit nationwide.The
city's population density, low automobile use and high transit utility make it
among the most energy efficient cities in the United States. Its greenhouse gas
emissions are 7.1 metric tons per person compared with the national average of 24.5. New Yorkers are collectively responsible for 1% of the
nation's greenhouse gas emissions though
they comprise 2.7% of the nation's population. The average New Yorker consumes
less than half the electricity used by a resident of San Francisco and nearly
one-quarter the electricity consumed by a resident of Dallas.
As of
July 2010 the city had 3,715 hybrid taxis in service, the largest number in any city in North
America.
In recent years, the city has focused
on reducing its environmental impact. Large amounts of concentrated pollution
in New York has led to a high incidence of asthma and
other respiratory conditions among the city's residents. The city government is required to purchase only the
most energy-efficient equipment for use in city offices and public housing. New York has the largest clean air diesel-hybrid and compressed natural gas bus
fleet in the country, and also, by mid 2010 the
city had 3,715 hybrid taxis
and other clean diesel vehicles, representing around 28% of New York's taxi
fleet in service, the most in any city in North America.
The city government was a petitioner
in the landmark Massachusetts v. Environmental
Protection Agency Supreme
Court case forcing the EPA to regulate greenhouse gases as pollutants. The city
is also a leader in the construction of energy-efficient green
office buildings, including the Hearst Tower among
others.
The city is supplied with drinking
water by the protected Catskill
Mountains watershed.As a
result of the watershed's integrity and undisturbed natural water filtration
system, New York is one of only four major cities in the United States with
drinking water pure enough not to require purification by water
treatment plans.
New York is the only US city in which
a majority (52%) of households do not have a car; only 22% of Manhattanites own
a car.
Architecture
Manhattan's skyline with its many skyscrapers is
universally recognized, and the city has been home to several of the tallest
buildings in the world. As of August 2008, New York City has 5,538
highrise buildings, with 50 completed skyscrapers taller than 656 feet (200 m).
This is more than any other city in United States, and second in the world,
behind Hong Kong.
New York has architecturally noteworthy buildings
in a wide range of styles. These include the Woolworth
Building (1913), an
early gothic revival skyscraper built with massively scaled
gothic detailing. The 1916 Zoning
Resolution required setback in new buildings, and restricted
towers to a percentage of the lot size, to allow sunlight to reach the streets
below.
The Art Deco style
of the Chrysler Building (1930), with its tapered top and steel
spire, reflected the zoning requirements. The building has distinctive
ornamentation such as replicas at the corners of the 61st floor of the 1928
Chrysler eagle hood ornaments.
A highly influential example of the international style in the United States is the Seagram Building (1957), distinctive for its façade
using visible bronze-toned I-beams to evoke the building's structure. The Condé Nast
Building (2000) is an
prominent example of green design in American skyscrapers.
New York's large residential districts are often
defined by the classic brownstone rowhouses, townhouses, and tenements that were built during a period of
rapid growth from 1870 to 1930. Stone
and brick became the city's building materials of choice after the construction
of wood-frame houses was limited in the aftermath of the Great Fire of
1835.
A distinctive feature of many of the city's
buildings is the wooden roof-mounted water towers. In the
1800s, the city required their installation on buildings higher than six
stories to prevent the need for excessively high water pressures at lower
elevations, which could break municipal water pipes.
Garden
apartments became
popular during the 1920s in outlying areas, including Jackson Heights in Queens.
Parks
The Statue of
Liberty National Monument, in New York Harbor, with the former Twin Towers of the World Trade Center in the background.
New York City has over 28,000 acres (110 km2)
of municipal parkland and 14 miles (23 km) of public beaches. This
parkland complements tens of thousands of acres of federal and state parkland.
National Park
System
Gateway National
Recreation Area is
over 26,000 acres (10,521.83 ha) in total, most of it surrounded by New
York City; the New York State portion includes the Jamaica Bay
Wildlife Refuge in
Brooklyn and Queens, over 9,000 acres (36 km2) of salt marsh, islands and water that includes most of Jamaica Bay. Also in Queens the park includes a significant
portion of the western Rockaway Peninsula, most notably Jacob Riis Park and Fort Tilden. Fort Wadsworth in
Staten Island with historic pre-Civil war era Battery Weed and Fort Tompkins,
and Great Kills Park with beaches, trails and marina also on Staten Island.
The Statue of
Liberty National Monument and Ellis Island Immigration Museum are managed by the National Park Service and are located both in the states of
New York and New Jersey. They are joined in the harbor by Governors Island
National Monument, located in New York. Historic sites under federal
management on Manhattan Island include Castle Clinton
National Monument; Federal Hall
National Memorial; Theodore
Roosevelt Birthplace National Historic Site; General Grant
National Memorial ("Grant's
Tomb"); African Burial
Ground National Monument; Hamilton Grange
National Memorial; and the Stonewall Inn in Greenwich Village is
a designated National
Historic Landmark as
the catalyst of the modern gay rights movement.
New York State
Parks
There are seven state parks within the confines
of New York City, including Clay Pit Ponds
State Park, a natural area which includes extensive riding trails,
and Riverbank State Park, a 28-acre (110,000 m2)
facility that rises 69 feet (21 m) over the Hudson River.
