What is a BMP?
Much of the cause of our polluted waters comes from stormwater runoff which enter our streams and rivers without treatment. Stormwater becomes polluted by: roadside oil & grease, pesticides from lawns & agriculture, sediment from construction sites, and carelessly discarded trash.
A BMP, or Best Management Practice, is a stormwater management and/or conservation practice that effectively controls movment of pollutants, prevents degradation of soil and water resources, and is compatible with the land use! BMPs can divided into two categories: structural and non-structural.
Structual: Structural BMPs can be thougt of as engineering solutions to stormwater management. Ex. stormwater ponds and opens channels.
Non-Structural: Non-Structural BMPs have no physical structures, but are designed to limit the amount of pollutants available in the environment that would potentially end up in stormwater runoff. Non-structural BMPs can be achieved through such things as education, management, and development practices. Some examples include ordinances and practices associated with land use and comprehensive site planning.
