*Shredded hardwood mulch is generally recommended for LID facilities. Its fibrous texture knits together somewhat; providing limited erosion control. In areas with particularly high flow (e.g. around inlets) inorganic mulch or coarse decorative aggregate or [[stone]] is recommended instead, as these will not float. All organic mulches have the potential to float and migrate in surface flow, after a previously dry period. <ref> Simcock, R and Dando, J. 2013.
