The urban areas in expansion, through the opening of new land parceling, require for their implementation, great movimentation and exposition of unconsolidated material, facilitating the appearing of erosive process. Monjolinho Stream's basin, in its superior part, fits in the kind of area next to the urban perimeter of Sao Carlos city (SP), consequently being submitted to an intensive antropic occupation. The objective of this work, with a preventive character, was to permit that, with the basic previous information, a land use and occupation chart can be elaborated in the future, including the basic zoning of the restrict occupation areas, the expansion urban areas and the common areas. Through the analysis of the results, it was observed that this region of Monjolinho stream's basin, mapped in the scale 1:10,000, doesn't show high potential areas to laminar erosion. There is a predominance of low potential areas (53% of total area), that can be explained by the great space occupied by pasturage, which keep the vegetal covering. The moderate potential areas (47% of total area) require being adopted steps to avoid the appearing and development of graver erosive process (rill and gully erosion).
