MEGALOPOLIS
MEGALO = very large POLIS = city Term created in the 1930s and used to describe any
large urban area created by the growth toward each other and eventual merging of two or more cities. (Lower-case “m”)
The French geographer Jean Gottman adopted the term in 1961 for the title of his book, “Megalopolis:TheUrbanizedNortheasternSeaboardoftheUnitedStates.”(Upper-case “M”)

Stretches over 500 mi. along the mid-Atlantic coast from Boston, MA to Washington, DC.
Some argue that it now extends 700 miles from Portland, ME to Norfolk, VA.
This region is defined by population density and urban land use.
Megalopolis: USA’s Urbanized Northeast
Made up of 117 contiguous counties in 12 states + DC that exhibit some urban characteristics.
There are 9 metro areas with over 1 million people; 11 with Richmond and Norfolk.
Referred to as the “Northeast Corridor” because it is linked by Interstate 95 and Amtrak.
See Textbook Ch. 5 and 14
This region has changed shape (got-ten longer and wider)
as new means of transportation allow
people to travel from distant areas
to its cities daily.

Megalopolis’s Landscapes
Includes large cities, small towns and rural areas where most of the people reside in an urban setting.
Urban places are link-ed by networks that allow people, goods, services and ideas to move easily. Vital for manufacturing.
Urban places have sub-landscapes.

Gottman’s studies in the 1950s noted an evolving densely pop-ulated landscape along the northeast coast of the U.S.
The five core cities (Boston, New York, Philadelphia, Baltimore, Washing-
ton) were growing toward each other to form one c.500 mi long large urban conglomeration.
This area has densities approach-ing 1,000 people/sq mi compared to the population density for the entire US of c.75 people/sq mi
IdentifyingLandscape
Change
FromJeanGottman,“Megalopolis:TheUrbanizedNortheasternSeaboardoftheUnitedStates,”1961
The area we call Megalopolis was once a rural landscape dotted with Indian villages, then a rural area with small colonial settle-ments. It became a rural area interspersed with factory-based cities. Something was “good here” to attract people and activities!
8
Urbanization will spread along transportation lines.The faster and more reliable the transportation, the greater the distance can be covered in the same period of time.

Creation of Megalopolis
This allows for expansion and the creation of a mega-city as conurbations merge and people move easily within the area.
CONURBATION: Smaller urban areas grow toward each other, filling the non-urban gaps between them. But they remain independent of each other, politically and services-wise.

Rural gaps are quickly being filled by suburb-anization and exurb-anization processes, mostly at the expense of farmland and other unprotected open space.

Defining Questions:Megalopolis as an Urban Region
Does this large region (land area and population) have the characteristics of an urbanized place?What are the unique circumstances that support its
creation? (site characteristics)
Are there situational advantages? (reasons for being)
Does it have pull factors? (“functions” and reasons to concentrate people).
Does it reap the economic advantages associated with concentration, accessibility, and movement (acting as both a collection and distribution point).
What types of spatial organization are present? (geopolitical needs to deal with intense and complex situations)
Has it evolved? (what changed; push factors; new pull factors)12

Beneficial Site Characteristics
Coastal location: allowed for regional trade and interaction with the world, esp. Europe.
Numerous estuaries and bays: good harbors.Moderate climate: cold winters, yet ice free harbors,
and ample precipitation for a fresh water supply.Variable soils: provided enough food for residents
but tended to be less productive than agricultural regions. (Better soils in the area south of Philadelphia).
Mixed forest: Variety of tree species provided wood for many uses.
Flat to gently rolling terrain: easy to use.Straddles two physiographic regions: includes
the Fall Line (site of water power).
13
Marks the border between the Appalachian Piedmont and the Atlantic Coastal Plain from NJ to GA.– Rapids and waterfalls are
present. Rivers flow from the Piedmont’s (hard rock) higher elevation onto the soft rock coastal plain.
Blocked inland water pas-sage from the sea; became portage sites.
These were the sites for the first colonial water mills that were the catalyst for urban development.

Cities developed at the Fall Line because ships reached the inland limit of river navigation and had to surrender their loads to land-based carriers (break-of-bulk/ portage site). Philadel-phia, Baltimore, and Richmond developed this way without any planning.
Other cities made use of the drop in elevation to build mills powered by the falling water, as Paterson and Trenton, NJ and Wilmington, DE.
SITUATION of Megalopolis
Good location for trade and immigration relative to Europe.Accessible. Along the natural “triangle” trade routes between Europe, Africa, the Caribbean, South America (wind/ocean currents).
Routes to the interior: natural and man-made, esp. Hudson-Mohawk corridor and the Erie Canal Convenient service point for ships sailing the North Atlantic routes.
16
The Hudson-Mohawk Corridor provided an easy and fast route from the Atlantic Ocean to the Great Lakes.
Access to the Interior (Hinterland)
The Erie Canal enhanced this route by providing an all water transit. It led to the rapid growth of NYC and NYS.
Of all east coast cities, only NYC had direct access to the inter-ior of North America (see Slide 5). Other ports were Europe-focused.By coincidence it also had the largest and best harbor.
17
Megalopolis the Region: Today
Locational significance of Megalopolis:
Has 17% of the total US population but only 1.5% of the total land area
20% of all U.S. export trade moves through its ports.
A region of international significance and influence.
Employment has shifted away from the factory to the office, service, management and technology fields.
Has the nation’s richest and poorest people, as well as its most and least influential groups.

Linkages inMegalopolis
Urban places of are linked by a dense transportation grid of road, rail, air and telecommunications. Water travel was important, too.

Landscape Developmentwithin Megalopolis
It began with settlement of New England and Mid-Atlantic areas: Massachusetts & Pennsylvania hearths.
N. American landscape took on a new appearance: English land-settlement scheme:– Town inhabited by farmers
and craftsmen located near water.
– Pasture/forest land admin-istrated by a local governing board: “Commons.”
– Cultivated land surround-ing the village.
• Growth of coastal towns neces-sitated movement inland for new farmland to supply food: con-nected to coastal towns by roads.
• New England towns (early 1800s)
were the first manufacturing areas of America: Yankee ingenuity/inventions.
• Mill towns (production specialty)
grew where there was water-power (site factor). 20
Today’s area is the northern portion of the
13 Original Colonies.
Colonists’ Sources of
WealthNew England/Mid-Atlantic settlements engaged in income-generating activities from available resources:
Fishing
Whaling
Ironworks
Naval stores (tar, pitch, turpentine from pine trees)
Shipbuilding21Rand McNally Atlas of American History
Town Plans

Docks within protected harbor (1777)
Strip village plan
Defensive site
Intersection of river and ocean
High ground with fresh water on a peninsula
Many of the original plats mimicked villages from where the settlers came.
Irregular Landscape Pattern within Megalopolis resulting from the
Metes and Bounds Land Survey System

This demarcation method can be seen in the shape of plots of land throughout Megalopolis including the shape of lots and the alignment of streets.
Landscape composed of parcels that vary in shape and size.
Landscape Developmentswithin Megalopolis
Sources of the visual landscape in colonial cities are evident: place names, land division and road networks.
Cities grew as people focused on best areas: economically sound, had links to the outside and were culturally inviting (pull factors).
Mid-Atlantic cities took on a European flavor and appear-ance because those colonies (NY, NJ, PA, DE, MD) where more tolerant of outsiders’ customs, languages and religions.
Technological developments changed their appearance (modernization): inventions, public health measures, construction methods, landscaped parks, paved streets, sewers, mass transit, etc.

Landscape Developmentswithin Megalopolis
Manufacturing grew in cities: sources of labor, money and ancillary services.
Cities’ need for workers attracted people: local farmers, laborers from other regions, and immigrants.
Transportation routes focused on the cities:need to move people, raw materials and finished products to market (ship/road/rail).
Subdivision occurred: manufacturing and warehousing districts; workers’ housing areas; ethnic neighborhoods; upscale sections for the wealthy and powerful; amusement parks: Later zoning.
Mountain and seaside resorts grew near cities: catered to both the wealthy and the worker: Leisure time.
Estates were established in areas around the cities (for the rich to get away from city conditions).

Houses of the rich and famous on land purchased outside of the city.
Evolution of the Urban Landscape
• As the inner city ages, becomes crowded, dirty and unsafe (a new
type of landscape; push factor), there is movement away by those who could
• Manufacturing areas begin to decay as facilities, structures and methodologies become outdated: industry abandons the city.
• Abandonment takes away jobs; tax base suffers.
• Housing areas (neighborhoods) begin to decay as workers move away and poverty levels rise.
Gentrification: land is bought by outsidersand takes on different usage: the character of the landscape changes again.
27
Evolution of Settlement Patterns: Population Redistribution
Growth of suburbs (1950s).
Out-migration of urbanites/suburbanites to small, distant towns between cities (1980s).
Clusters of high-rise buildings (office and residential)
in the CBD/central business district (1990s).
Slowing of movement out of city centers.
Movement back to cities: “gentrification” (2000s).
• Attraction of jobs/amenities to higher-income workers.
• Displacement of low-income residents.
• Ethnic neighborhoods change.
• Aging, changing, expensive suburbs (sprawl, min. services)
28
Gentrification
The process of change that occurs when wealthier people (the “gentry”) buy and move into housing property in urban areas where the existing population is less prosperous.
Includes the conversion of properties (as warehouses and
factories) into upscale uses.
Characteristics of neighbor-hoods change including the visual landscape.

Urban Landscape Development
The development of an urbanized area takes on a life cycle.
1. Creation (reason for being)
2. Growth
3.Stagnation
4. Demise
5. Resurgence
Resurgence leads to the creationof a new identity.

Megalopolis has a Human-dominated Landscape
How has urbanization altered the region’s ecological landscape?
1. Damaged/destroyed native biomes.
2. Has lead to a conflict betw native and introduced species.
3. Changed the area’s hydrology (stream diversion, wetlands drainage, pumping groundwater, paving, slope alteration).
4. Altered shorelines (land fill; hardening; groins/jetties)
5. Created microclimates (reduced open space; concrete and asphalt surfaces).
6. Polluted its area (air, water, land, noise).
7. Has increased the dangers from natural processes, now deemed hazards.
31
PROBLEMSfacing Megalopolis and its cities
Can urban problems be visualized?
Can a “problem” urban landscape be recognized?
Once recognized, how are they dealt with?
Congestion: large numbers of people and vehicles: need for adequate transportation systems, housing and services
Health Issues: food, water supply, waste management, controlling disease, dealing with dying and dead people.
Quality of Life Issues: crowding, crime, poverty, health care, pollution
Pollution: air, water, land, noise
Hazards: storms, rising sea level, flooding, fire, terrorism32
