The incidence in flooding events in Puerto Rico is a matter of concern for the citizenship. Increases in precipitation and urbanization are critical for flooding events. Flooding events from 1980 to 2010 were taken from Storm Data to compare it with population and housing from the U. S. Census Bureau and precipitation data were used from XM Climate Access Online. Precipitation data of the National Weather Service from 1980 to 2010 of thirty one stations was used to compare it with the flooding events. The purpose was to look for the incidence of floods in Puerto Rico in urbanized areas and observe possible adjustments that could be taken to prevent it.
