2 © 2011 Pearson Education, Inc. I. Urban Expansion A. Annexation –Process of legally adding land area to a city Common in late 19 th & early 20 th C. –Received better urban services Less common today – prefer local services B. Defining urban settlements 1. The city – a legal entity –Local gov’t system w/ fixed boundaries –Generally population has declined since 1950 – why? –Growth of central cities – city surrounded by suburbs 2. Urbanized areas – a continuously built-up area –Difficult to define –City and all contiguous built-up suburbs w/ specific density (1K ppl./mi.)

Metropolitan areas – a functional area Metropolitan statistical areas (MSAs) –Specific statistical area – cities of 50K or more & includes people in surrounding coutnies that work in city »Based on counties – census data available »366 MSAs as of 2009 –Similar to old standard metropolitan stat. area (SMSAs) –Micropolitan statistical areas (mSAs) – cities of 10K-50K »US has 574 –Core based statistical areas (CBSAs) – combo of MSAs & mSAs –Combined statistical areas (CSAs) – many mSAs are tied to MSAs – 124 in US –Primary census statistical areas (PCSAs) – CSA + remaining MSAs & mSAs = PCSAs

Local government fragmentation Little communication & coordination among local gov’t Council of government – cooperative agency of several local areas to oversee common planning (roads, etc.) –Ex.: Consolidations of city and county governments – Indianapolis, Miami –Ex.: Federations - Toronto D. Overlapping Metropolitan Areas Combination of MSAs among regions –Area belongs to several MSAs megalopolis – “great city” – Boston to Washington corridor (“Boswash”) –Other ex: midwest – Chicago to Pittsburgh; CA to Tijuana; Ruhr valley (Ger.); Tokaido (Japan)

Peripheral Model Overview Created by Chauncey Harris (multiple nuclei) peripheral model – urban area w/ other nodes in surrounding suburban areas tied by beltway Edge cities – nodes of consumer or business services on beltway –A. Density gradient –Number of houses diminish w/ distance from center of city –B. Cost of suburban sprawl Spread of development over surrounding area –Need new roads & utilities, construction –Loss of agricultural land –greenbelts – rings of open space (common in Europe) –Smart growth – preservation of agricultural land w/ growth

Residential Segregation Areas often informally segregated due to costs –socio-economic segregation –zoning ordinances – prevent residential & commercial areas –B. Suburbanization of Businesses 1. Suburbanization of Retailing –Growth of malls & shopping centers 2. Suburbanization of Factories & Offices –Attracted to larger spaces, cheaper lands, access to highways

Advantages of public transit –Transit travelers take up less space –Cheaper, less pollutant, more energy efficient than an automobile –Suited to move large number of people to small area 2. Public transit in the United States –Used primarily for rush-hour workers to/from CBD –esp. NYC, Bos, SF, DC, Chi, Phi –Small cities have minimal use –Most Americans prefer to commute by car
