Gourt Home::Gourt :: Geography and environment of New York City
The geography and environment 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
The Hudson River flows from the Hudson Valley into New York Bay, becoming a tidal estuary that separates the Bronx and Manhattan from New Jersey. The East River, really a tidal strait, stretches from the Long Island Sound to New York Bay, separating the Bronx and Manhattan from Long Island. The Harlem River, another tidal strait between the East and Hudson Rivers, separates Manhattan from the Bronx.
Upper New York Bay is surrounded by Manhattan, Brooklyn, Staten Island, and the coast of New Jersey, and is connected by the Narrows between Brooklyn and Staten Island to Lower New York Bay, which is partially surrounded by Brooklyn, Staten Island, and the coast of New Jersey, and opens to the Atlantic Ocean.
The shape of the land has been altered substantially by human intervention, with considerable land reclamation along the waterfronts since Dutch times, most dramatically in Lower Manhattan, and continuing in modern developments like Battery Park City. Much of the natural variations in topography have been evened out, particularly in Manhattan (one possible meaning for Manhattan is "island of hills"; in fact, the island was quite hilly before European settlement). A number of smaller islands have been artificially enlarged, and the map of islands in Jamaica Bay has been completely transformed.
Climate
New York City has a humid climate, vastly affected by its proximity to the Atlantic Ocean.
- Winters are typically cold, but milder than Cleveland. 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 billions of dollars 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 flucuate quickly at these times of year.
- Temperature records have been set as high as 106 °F (41 °C) on July 9, 1936 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 six decades. Most recently, temperatures have hit 100 degrees as recently as July 2005 and dropped below zero as recently as January 2004. New York can have excessive days of rain or long streches of dry weather.
According to the United States Census Bureau, the city has a total area of 1,214.4 km² (468.9 mi²). 785.6 km² (303.3 mi²) of it is land and 428.8 km² (165.6 mi²) of it is water. The total area is 35.31% water. Although most of the city is adequately above sea level, parts of it could be threatened in the future if the current patterns of global warming continue.
Environmental issues
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."SustainLane US City Rankings." March 2006.* 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.
New York 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.
Water supply
Many of the city's environmental assets are related to geography and a long tradition of environmental stewardship in the mountain ranges north of the city. New York's water supply is fed by a 2,000 square mile watershed in the Catskill Mountains. Because the watershed is in one of the largest protected wilderness areas in the United States, the natural water filtration process remains intact. As a result, New York is one of only five major cities in the United States with drinking water pure enough not to require processing by water treatment plants."Maintaining Water Quality that Satisfies Customers: New York City Watershed Agricultural Program." New York City Department Of Environmental Protection 20 Nov 1998.*Energy efficiency
The city's unique density, encouraged by much of it being surrounded by water, facilitates the highest rate of mass transit use in the United States. New York is one of the most energy efficient cities in the United States as a result. Gasoline consumption in New York is at the rate the national average was in the 1920s.Jervey, Ben. "The Big Green Apple: Your Guide to Eco-Friendly Living in New York City." See Metro New York article: The city's mass transit system, multifamily housing, mixed neighborhoods and the fact that developments no longer go up on virgin land make building in New York very energy efficient. While New York City has a larger population than all but eleven states, if it were granted statehood it would rank 51st in per-capita energy use.Owen, David. "Green Manhattan." The New Yorker 18 Oct 2004.[http://www.greenbelt.org/downloads/resources/newswire_11_04GreenManhattan.pdfNevertheless, New York faces growing energy demands and limited space. The city has introduced a series of innovative environmental policies since the 1990s to address these problems. These include a raft of detailed measures, such as switching more than 11,000 traffic lights and "Don't Walk" signals in the city to new energy-efficient light-emitting diodes that use 90% less energy than conventional fixtures. The city will also replace 149,000 "cobra head" street lights with new energy efficient designs by 2008. Over 180,000 inefficient refrigerators in public housing projects have been replaced with new ones that use a quarter of the power of the old ones. By law, the city government can purchase only the most efficient cars, air-conditioners and copy machines."It Never Sleeps, but It's Learned to Douse the Lights." The New York Times 11 Dec 2005. The electricity used to power the Statue of Liberty, Ellis Island and 22 other federal buildings in New York City, an annual electricity demand of roughly 27 million kilowatt hours, is provided by wind power."Wind Power In NYC." Gotham Gazette Mar 2006.[http://www.gothamgazette.com/article/environment/20060308/7/1782
New York City is home to several clean energy projects. The most significant is the installation of underwater turbines in the East River to take advantage of tidal currents. Designed by researchers at New York University, six windmill-like turbines with three 8 foot-long blades are being installed just north of the Queensborough Bridge. They will supply electricity to Roosevelt Island. After an 18-month trial, an additional 300 slow-moving, widely spaced turbines will be installed. They will generate enough clean energy for 8,000 homes. Planning is also underway to construct windmills on a hill in the former Fresh Kills Landfill. The wind energy project would power 5,000 homes on Staten Island.
Green building
For years New York City was slow to embrace green building guidelines used in cities like San Francisco to promote environmentally-friendly construction. In the post-World War II construction boom, changes in zoning regulations and the widespread use of air conditioning led to the design of sealed glass and steel towers. Without natural sources of light and ventilation, such buildings required large amounts of fossil fuels to operate.This phase of building style is rapidly changing in New York, which has become a leader in energy-efficient green office buildings like 7 World Trade Center, which recycles rainwater and uses it in toilets and for irrigation, and computer-controlled heating and lighting. The United States Green Building Council estimates 3,000 new green apartments in New York City have been built since 2001.
In 2000 the state of New York introduced a green building tax credit, the first one of its kind in the United States, that has allowed some developers of environmentally friendly buildings to write off as much as $6 million on their tax bill. The city's Department of Design and Construction developed a set of guidelines in 1999 that encourage environmentally sound building methods for municipal projects. The guidelines had led to approximately $700 million in green city construction projects by the end of 2005."Green Buildings." Gotham Gazette 5 January 2004.* In 2005, New York City mandated that nonresidential public buildings costing $2 million or more be built to standards set by Leadership in Energy and Environmental Design (LEED), which grade buildings in areas like energy and water consumption, indoor-air quality and use of renewable materials. The legislation also applies to private projects that receive $10 million or more in public funds or half of whose budgets come from public money.
Farmers' markets
In 1976 the Council on the Environment of New York City established the Greenmarket program, which provided regional small family farmers with opportunities to sell their fruits, vegetables and other farm products at open-air markets in the city.The most famous is the Union Square Greenmarket, held Mondays, Wednesdays, Fridays, and Saturdays between 8 AM and 6 PM for six months each year. 250,000 customers a week purchase 1,000 varieties of fruits and vegetables at the market. The variety of produce available is broader by perhaps a factor of ten than what is found in a conventional supermarket.
The Greenmarket program manages 50 other markets in 37 locations in the five boroughs. More than 100 New York City restaurants source their ingredients from Greenmarket farmers each week; Greenmarket farmers also annually donate about 500,000 pounds of food to city food pantries each year.
164 farmers travel a median distance of 90 miles to attend the markets, including 90 vegetable and orchard growers, 29 meat, dairy, poultry, wool and fish producers, 12 producers of honey, maple syrup, jam, and wine, 19 growers of plants and flowers, and 14 bakers.
In 2006 the City Council annouced it would make farmers' markets the centerpiece of efforts to reduce hunger and increase awareness of nutrition in the city, especially in lower-income areas, and that 10 new farmers' markets would open serving low-income neighborhoods including public housing projects.
Air pollution
Air pollution, while not as severe as in cities like Los Angeles or Beijing, remains a problem. The city's air has high levels of ozone and particulates, and residents in some neighborhoods have very high rates of asthma. Air pollution is an ongoing political issue in neighborhoods that contain bus depots.The 2004 annual report of the American Lung Association ranks New York City as 18th of the 20 regions in the United States most affected by year-round particle pollution, behind Los Angeles, Atlanta, Chicago, and Modesto, CA among other cities."State of the Air: 2004." American Lung Association.* New York City ranks 13th of the 20 regions most affected by smog, behind Los Angeles, Houston, Dallas, Washington, D.C., and Philadelphia, among others. While none of the outer boroughs of New York City rank in the top 25 U.S. counties most polluted by annual particle pollution, Manhattan ranks 22nd.
The city has made efforts to reduce particle pollution with measures like fitting catalytic converters to the exhausts of diesel city buses. New York also has the largest hybrid bus fleet in the country, and some of the first hybrid taxis. A large percentage of the city-owned vehicle fleet, including the personal cars of top city officials, are required since 2005 to be fuel efficient hybrid vehicles like the Toyota Prius or Honda Accord gas-electric sedan that produce minimal particulates and carbon dioxide emissions. In 2005 the city's vehicle fleet had 6,000 alternative fuel and 70 electric vehicles. A biodiesel processing plant will soon open in Brooklyn that will process 2.5 million gallons of biodiesel a year and distribute it to conventional gas stations in the city.Jervey, Ben. "The Big Green Apple: Your Guide to Eco-Friendly Living in New York City." See Metro New York article:*
The Department of Sanitation, which has 1,500 trucks of its 2,200-vehicle fleet on the streets each day, is working with truck manufacturers to introduce gas-electric hybrid garbage trucks. The Department switched to using low-sulfur fuel in 2001 and uses corn-based ethanol in 500 of its 1,500 light-duty trucks."Eco-rig a Sanitation Sensation." The New York Post 3 April 2006.
Transit use
New York is distinguished from all other American cities by its use of public transportation. While nearly 90% of Americans drive to their jobs, public transit is the overwhelmingly dominant form of travel for New Yorkers.Bureau of Transportation Statistics, U.S. Department of Transportation.According to the 2000 U.S. Census, New York City is the only locality in the United States where more than half of all households do not own a car (the figure is even higher in Manhattan, over 75%; nationally, the rate is 8%).Bureau of Transportation Statistics, U.S. Department of Transportation.*" target="_blank" >and David Owens. Only 6% of shopping trips by New Yorkers involve the use of a car.[http://www.transalt.org/press/releases/060223necessity_choice.html "Necessity or Choice? Why People Drive in Manhattan." Transportation Alternatives Feb 2006. The city's extraordinary public transit use means that New Yorkers emit far fewer greenhouse gases on a per capita basis than the average American.Greenpoint oil spill
The Greenpoint neighborhood of Brooklyn was once home to many oil refineries for more than a century. In 1950, the predecessor of the ExxonMobil oil company is alleged to have spilled 17 million gallons of oil into Newtown Creek in what is one of the worst oil spills in United States History. Oil continues seeping into a city waterway decades after the leak was first noticed.The oil business has largely moved elsewhere, but countless small and large spills went unnoticed for decades and eventually formed a subterranean blob of more than 50 acres. Authorities have been aware of the problem since 1978. Exxon Mobil accepted responsibility for much of the damage in 1990 and has since pumped some nine million gallons out of the ground.
The slow pace of the cleanup, however, has increasingly angered Greenpoint residents and elected officials, who have launched a series of lawsuits against Exxon in 2005. In June 2006 the New York State Department of Environmental Conservation announced it would sue Exxon Mobil to hasten completion of the cleanup.
Other issues
Much of the city's housing stock is old, and lead paint is an ongoing public health issue. Environmentalists and city officials have also struggled to establish a longterm garbage disposal plan for the city. Some parts of the city are also at risk if current global warming patterns continue and sea levels rise.External links and further reading
