The goal of this article is to present an analysis of the politic relations between the participants of the Secretary of Regional Development (SRD) in Blumenau. It is an interdisciplinary research and that can be understood from the so-called environment sciences. The studied aspects to supply crucial data for this research are the political relationship between the cities and with the state government. The structure of the SRD, as well the way cities evaluate themselves, resulted in proposals of intervention and institutional practices that assimilates individual and collective demands, and also shapes somehow the economic and politic organizations in its scope. Previously, the process of development was local and focused on an individual region that was defined by the irregular creation of new cities within the same region. The implementation of this decentralization model promotes the experimentation of a developmental dynamic, that intents to create homogeneity and the flatness of a region. This logic is perceptible as the cities belonging to a same regional assume their problems, overall the education and health, because they can be understood like public activities, and their neighbor's cities problems with several potential and politic representatives. This occurs by sustainable political and administrative procedural that promote an inclusive development and harmonized, propitiated by the formal instances and legitimized by the institutionalism which supports them.
