Flooding in urban centers has been treated as a direct consequence of excessive rainfall, without considering the integrated functioning of the drainage system. These problems have caused engineers to propose auxiliary solutions or techniques that assist urban drainage. The objective of this study was to analy ze the technical feasibility of using compensatory measures such as permeable pavement, for tunnel accesses, as an aid to existing drainage. The soil of the unpaved regions, which represent only 16.3% of the study area, was characterized using the Beerkan method, followed by an analysis of the water balance of the region using the Hydrus-1D computational model, in order to determine the rainfall on the unpaved regions surrounding the tunnels. The water balance of this portion of the study area showed that, of the 239.69 mm.m -2 that precipitated over unpaved areas, 88.15% infiltrated and the remaining 11.85% ran off or evaporated. In addition, infiltration tests showed that the soil is mostly sandy and capable of permitting infiltration of the water precipita ted during the year studied, so the proposal to use permeable pavement at the entrance and exit of the Chico Science Tunnel is viable, minimizing flooding as well as maintenance costs for the booster pumps used by the current drainage system.
