[[File:Screenshot 2025-11-12 162221.png|400px|thumb|right|Rolled erosion control products (RECP) should be installed according to manufacturuer instructions. In general, RECP on steep slopes should be installed down the slope, extend to the top of the slope, use an anchor trench at top and bottom, be in continuous contact with soil surface and overlap. RECP installed in ditches/channels should be installed parallel to flow direction, be anchored to top of slope on both sides, be in continuous contact with soil surface, and overlap. Air pockets between the RECP and soil will allow stormwater to pass through and erode the soil below.

The end runs of any perimeter controls should extend a sufficient distance up slope to prevent flow from going around the control measure.]]
