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:The

Megalopolis’s
Landscapes
Includes large cities, small
towns and rural areas where
most of the people reside in
an urban setting.
Urban places are linked by networks that
allow people, goods,
services and ideas to
move easily. Vital for
manufacturing.
Identifying
Landscape
Change
The area we call Megalopolis was once a
rural landscape dotted with Indian villages,
then a rural area with small colonial settlements. It became a rural area interspersed
with factory-based cities. Something was
“good here” to attract people and activities!
Gottman’s studies in the 1950s
noted an evolving densely populated landscape along the
northeast coast of the U.S.
The five core cities (Boston, New
York, Philadelphia, Baltimore, Washington) were growing toward each

But they remain independent of each other, politically and
services-wise.
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.
This allows for expansion and the creation of a
mega-city as conurbations merge and people move
easily within the area.
Rural gaps are quickly
being filled by suburbanization and exurbanization 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)

Great Falls of the Potomac
Beneficial Site Characteristics
The Fall Line
 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).
A unique regional feature
 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.
FALL LINE
 Blocked inland water passage from the sea; became
portage sites.
 These were the sites for
the first colonial water
mills that were the catalyst
for urban development.

SITUATION
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). Philadelphia, 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.
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.
15
Access to the Interior (Hinterland)
16
Megalopolis the Region: Today
Of all east coast cities, only NYC had direct access to the interior of North America (see Slide 5). Other ports were Europe-focused.
By coincidence it also had the largest and best harbor.
The Hudson-Mohawk Corridor provided an easy and fast route
from the Atlantic Ocean to the Great Lakes.
The Erie Canal enhanced this
route by providing an all
water transit. It led to the
rapid growth of NYC and NYS.
17
 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.

 Out-migration of urbanites/suburbanites to small,
distant towns between cities (1980s).
 Clusters of high-rise buildings (office and residential)

 Slowing of movement out of city centers.
 Movement back to cities: “gentrification” (2000s).

Development Sequence
The development of an urbanized area takes on a life cycle.
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 neighborhoods change including the
visual landscape.

Resurgence leads to the creation

Human-dominated Landscape
PROBLEMS
facing Megalopolis and its cities
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
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, terrorism
