COMPARATIVE ANALYSIS OF DENSITY PATTERNS OF CINCINNATI AND PORTLAND METROPOLITAN REGIONS 1970-2000

by GURNANI, NITIN M

Abstract (Summary)
It is debatable whether regional planning is an effective tool to solve the complex and interconnected problems facing the American metropolitan regions today. The study aims to test the hypothesis by comparing the metropolitan growth patterns of Cincinnati and Portland, as Portland has been proactive in the field of regional planning, whereas Cincinnati has made limited efforts in the direction. The aim is to conclude whether the approach adopted by Portland has been more effective in restricting the trends of de-centralization and outward migration, than Cincinnati. To compare the dynamics of metropolitan growth, the density patterns of the two metropolitan areas are compared for the thirty-year period from 1970-2000. Two methods are used to do so: density gradients and zones of urbanization. The density gradients of the metropolitan areas are created using two regression models: negative exponential and cubic polynomial. In zones of urbanization methodology, the entire metropolitan area is divided into five definite zones: core area, inner city, inner suburb, outer suburb, exurban area, to compare the location and quantity of growth in each of these zones. The study found that Cincinnati metropolitan area experienced the phenomenon of outward migration and decentralization, whereas Portland experienced suburbanization without the ill effects of decentralization. It was found that the approach adopted by Portland had limited positive impact on the growth patterns like restriction of outward migration, but the approach proved unable to control the process of suburbanization. It was also found that the approach adopted by Cincinnati resulted in sprawling metropolitan growth patterns as the region continued to decentralize and suburbanize.
