Deep rooting [[perennial]] grasses or a mixture of [[wildflowers]] and [[shrubs]], tolerant to both wet and dry conditions and [[salt]]; roots uptake water and return it to the atmosphere, provide habitat for organisms that break down trapped pollutants and help maintain soil structure and permeability

Structures constructed of a non-erosive material, such as suitably sized [[Reservoir aggregate|aggregate]], wood, gabions, riprap, [[stone]] or concrete; used to slow runoff water. Can be employed in practices such as bioswales and enhanced grass swales. Constructed across a drainage ditch, [[swale]], or channel to lower the speed of concentrated flows for a certain design range of storm events and to promote infiltration.

*Check for signs of oil or grease contamination (e.g. sheen on surface of water when sediment is submerged). I suspected, submit a sediment sample for contaminant testing by an accredited laboratory to determine the proper disposal method.

 

*Woody vegetation should not be planted or allowed to become established where snow will be piled/stored during winter.
