A well designed forebay will distribute the flow, reducing erosion around the inlet. One effective way of achieving this is by surrounding the pad with some form of level spreader on all sides. The level spreading could be a sharp crested weir in metal or concrete, or be soft edged with irregular landscaping [[stone]].

For BMPs serving up to 2 Ha catchment area, a significant forebay may not be required. However, for larger catchments or those with heavy sediment loading a properly sized forebay will help prevent clogging of the filter media and ease maintenance requirements of [[bioretention]] facilities.
