EC-1 Surface Roughening (SR) <br /> Maintenance and Removal <br /> Care should be taken not to drive vehicles or equipment over areas that have been surface roughened. <br /> Tire tracks will smooth the roughened surface and may cause runoff to collect into rills and gullies. <br /> Because surface roughening is only a temporary control,additional treatments may be necessary to <br /> maintain the soil surface in a roughened condition. <br /> Areas should be inspected for signs of erosion. Surface roughening is a temporary measure,and will not <br /> provide long-term erosion control. <br /> SR-2 Urban Drainage and Flood Control District November 2010 <br /> Urban Storm Drainage Criteria Manual Volume 3 <br />
