Urban Flooding


Urban Flooding is a hazard to many parts of the country causing harm to both the environment and humans. As more and more parts of our plant is being urbanized, these urban areas are paved in concrete in place of plantlife. Instead of lush natural landscapes that soak and thrive in soft rainwater with organic minerals, the excess run off becomes a detriment unable to get past the compacted manmade soils of asphalt and cement that have encrusted the earth. The run off becomes repelled from our earth instead of absorbed in a natural ecosystem, causing dangerous floods. In addition, the layer of urban runoff carries air and ground pollutants on a path of least resistance into natural areas. On an extremely rainy day, groundwater sewage lines become clogged by the trash that the run off carries into the pipes. With more urban green space, this problem can be greatly alleviated Just by simply incorporation green space into preexisting areas like sidewalks, pathways, and parking lots.
