Does all this rain recently show why we need to design in a way that controls runoff?

    There are many problems associated from storm water runoff from nonporous materials like streets and building. The runoff brings with it pollution in the forms of toxins and nutrients which can pollute water systems. Eutrophication of lakes is often due to storm water runoff carrying with it sediment from construction sites. This contains limiting nutrients which cause massive algal blooms in lakes taking away from the lakes aesthetic value as well as making it difficult for fish species to live. The algae choke off oxygen to the lakes causing dead zones below the surface. This is not new news, however, and greater precipitation is not likely to change design policy for new construction. Efforts have been made using retention ponds, but nothing has proven to be totally efficient in controlling runoff.
