The present article intends to relate the conception directly to the use of the sustainable development with the effective processes of territorial planning originated in the political constitution of 1991 and in the Law 388 of 1997. It leaves of the basic hypothesis that the sustainable development as principle rector of the public politics, it should kick all perspective and development strategy from the National Plan of Development, until the Municipal Plans of Development, going by the Departmental Plans of Development and of course fundamentally for the Plans of municipal territorial classification. It is stood out as an aspect that darkens this integralidad possibility among the planning to all the scales and the sustainable development, the nonexistence -to these heights - of a Organic Law of territorial Classification -LOOT -, what also crawled negatively to that inexequible of the Law 388 of 1997, the possibility was declared that Departments and metropolitan Areas can formulate their respective plans of territorial classification.
