As the following specific issue sheets indicate, there have been considerable data and information compiled which contribute to an understanding of the project's environmental impact. More refined analyses of most of these impact issues \vould require additional data development. The following are general comments regarding refinement of either data or methodology: 9 Natural physical environment impacts mostly require more definitive analysis of existing data and/or data v\fhich is readily synthesized. d Built physical environment impacts require more graphic presentation of changes proposed in the structural form of the project site and environs. New use relationships to existing utility and circulation systems require better correlation of program proposals with the capacities of existing systems. a Socio-Political environmental impacts have been described primarily in terms of urban redevelopment objectives and urban social structure. The demands of the changing social structure on the municipal service system, however, have not been fully investi^iated. Economic environmental impacts have stressed the attractive aspect of a major private - public development interest, but there is need for a more com.prehensiva analysis of public costs and benefits, with particular emphasis on those indirect costs required for the development and m.aintenance of public infrastructure to serve tlie project.
