This research presents the result of the engineering geological mapping in a 1:50.000 scale, in Bairro do Peão region, in Piracaia (SP), represented by means of homogeneous units which are susceptible to superficial dynamic processes. To serve as basis for the elaboration of a Chart of Susceptibility to Processes of Superficial Dynamic, a series of physical samples was collected, considering erosive processes and registers of information of usage and soil occupation. The procedure used for elaborating the geotechnical chart is based on Vedovello (2000), which suggests the physiographic compartimentation of the area through photointerpretation and further geotechnical characterization of the selected samples. The geotechnical characterization of the samples was made by identifying the features and properties of the material and forms of the physical environment determining the geotechnical conditions through geological-geotechnical profile descriptions typical of/ peculiar to each unit defined in the area. Thus, for each unit selected, the susceptibility level was established in very high, high, average and low, as well as the prevalent erosive processes.
