Stormwater Runoff from Commercial Areas

Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. Imervious surfaces include areas such as: 

As the runoff flows over the land or impervious surfaces, it accumulates potential pollution from:

These can adversely affect water quality when the runoff is not treated before it is discharged to waterways. 

What can municipal officials do?

Low Impact Development (LID) is a set of best management practices that works with nature to manage stormwater as close to its source as possible. This approach to land development (or re-development) employs principles such as: Pixelated photo of a LID technique

These achieve appealing site drainage, transforming stormwater from a waste product into a resource or component of the development. Examples of various practices include:

The primary principle of LID is very simple: soak the water back into the ground BEFORE is gets contaminated. Traditionally stormwater management techniques seek to dispose of stormwater.
