The city of Toledo-PR, known as a major producer of grains, fowl and pigs, has been outstanding in recent years due to its urban development. As a consequence of this growth, we have a decrease in the area of permeable soil and with that, it causes an increase in the erosive processes of the region, and the silting of streams, rivers and lakes. So the present work had as objective to locate and classify some erosive features, in order to have a spatialization of events and try to identify what has caused the emergence of events, what risks these erosions cause the population that lives in the place, as well as propose solutions for these problems. This analysis was carried out through the creation of a georeferenced database with 12 erosive features and with the aid of the QGIS software, a distribution map of these features was produced, comparing their locations with the distribution of roads and waterways in the region. After the production of the map, the results were analyzed through the data collected in the field, and it was observed that 50% of the analyzed cases occurred near paved and unpaved roads, due to the lack of adequate drainage. Through this study, it will be possible to prepare legislative documents to control land use and occupation in the future, as well as to establish improvements in the drainage system in certain regions of the county.
