RAN: Redesigning the American Neighborhood Project
Stormwater Basics: Background
Stormwater management has become a front burner issue for environmental, economic, and social reasons:
- Stormwater can affect not only ecological systems but human health and well being. It is a vehicle or mechanism by which pollutants are carried downstream to our streams, rivers, and lakes.
- We pay the economic price of stormwater mismanagement: The costs of after-the-fact stormwater management are high, most particularly "end of the pipe" or downstream solutions, which are often passed along to the taxpayer via property, water, and sewer taxes.
- Stormwater mismanagement can adversely affect valuable and valued public resources, such as Lake Champlain. Further, private property can be adversely affected as a result of erosion and flooding.
In the following pages we explain some of the most important issues related to stormwater dynamics, quantity, and quality. We start with a short presentation showing why stormwater became such an issue in the recent past. You can advance through the presentation by pressing the buttons; also note the text in the window on top for some comments.
Many of the problems associated with stormwater are caused by the simple fact that we are rapidly changing the landscape where we live. This change in land use over the past 60 years has been rapid, leaving fewer natural landscapes and dramatically increasing areas that are impervious, where water can no longer infiltrate into the ground.
