The fate of planned Ur development & redevelopment largely depends on the pot system. In the US, pot & gov'al fragmentation has crucial consequences for development in physical, soc, & poi'al ways. The federal system raises barriers which impede accommodation. The multiplicity of local units of gov, not rationally determined, undermines co-ordination, power, & responsibility. The outcome of diffusion of power & dilution of responsibility is rigidity. Ur renewal is limited by the dichotomy of public & private control, tension between federal & municipal agencies, division of power between diff federal agencies, & fragmentation of power at the local community level. Any change will require some adjustments in perspective. The possibilities for change, however, do not rest upon basic changes in pol'al norms but on exp'tion in their application. In conceptions of community the units have probably been too small, applying to limited, exclusive groups organized around shared activities. These come together, partially & fortuitously, in the Ur scene, where the only encompassing org is the pol'al community. The pol'al side of Ur development & redevelopment is inescapable. AA.
