What is a BMP?
BMP stands for Best Management Practice. Stormwater BMPs are designed to remove pollutants from urban runoff, improve water quality, and control quantity before the water reaches our rivers and streams.
There are two categories of BMP’s, "structural" and "non-structural". Non-structural BMPs have no physical structures associated with them, and they are designed to limit the amount of pollutants that could end up in stormwater runoff. Non-structural BMPs can include minimizing the amount impervious area for site development, providing a vegetative buffer along local water bodies, incorporating existing landscape features in a site plan, and educational outreach programs. Non-structural BMPs tend to be less costly than structural BMPs, and can work with structural BMPs to lessen the amount of stormwater runoff that would need to be treated.
Structural BMPs are permanent fixtures that are constructed to treat stormwater runoff. Structural BMPs are part of a comprehensive plan to reduce stormwater pollution. Without structural BMPs, pollution from urban runoff would directly enter Fayetteville's rivers and streams, which would harm aquatic life and potentially degrade the quality of drinking water. Types of structural BMPs that are approved in the Administrative Manual are: wet detention ponds, dry detention ponds, stormwater wetlands, bio-retention ponds or rain gardens, infiltration devices, grassed swales, etc. For more information on the specifications of these BMPs, please refer to the Administrative Manual. The City of Fayetteville often refers to the North Carolina BMP manual issued by the North Carolina Department of Department of Environmental Quality.
