The chosen area for this research is the Juquery State Park, located at Franco da Rocha municipality in São Paulo Metropolitan Region, in a region with historical flood, slip, and mainly erosive process. In 2011, the Franco da Rocha city was isolated due to flooding of Juqueri River (northern limit of the research subject area) and landslides blocked the city access. The study proposes do a geological and geotechnical mapping in scale 1: 20.000, associated with characterization of the identified units, as well as the evaluation of units in relation to susceptibility to erosion and landslides processes. Thus, the survey aims to provide subsidies for development of environmental management tools, once the management plan is in contracting stage, the characterization of physical environment is important for their development appropriately. In the long term, it is expected reduce impacts of geological processes, and consequently the reduction of efforts and resources spent by the government to answer emergencies. The method for geological and geotechnical characterization is based on the technique of integrated physiographic analysis, which is supported by literature, observation and interpretation of aerophotogrametric images (photoanalysis), correlation of numerical model products of land, land field work. In order to analyze and compare the use and occupation of land in 1977 and 2010/2011, the partitioning of the park area was held on 5 units of interest, using techniques photo interpretation and manual classification. To evaluate the susceptibility of units was adopted graphical analysis method, which is based on a combinatorial analysis of interest variables. The mapping subdivided the area in six geological and geotechnical units. Consolidation, characterization and distribution of the units are presented in the geological and geotechnical map, which contains summary table with characteristics of mapped drives, and the chips that...
