Improved Channel. If it is determined that topography of the regraded area is such that drainage is <br />concentrated into a particular area, drainage wntrol will be improved. The drainage bottom or channel will <br />be reshaped, if needed. This will be done with either a motor grader or dozer, making the channel in the <br />shape of a V that is approximately 16 feet to 20 feet wide. The channel bottom will either be seeded, <br />covered with erosion matting and seeded, or rocked. The method used will depend on site conditions. <br />Continued observations will be made of this area for additional problems or necessary maintenance. <br />No Defined Channel. On a slope where there is no Swale or defined channel, a number of operations will be <br />performed, depending on the eMent of the erosion. The area will be disked on the contour or erosion <br />matting will be placed on the area, depending again on site characteristics. Reseeding will then take place. <br />In addifrort to the above, contour furrows in and above the erosion area may be constructed to intercept and <br />slow down the runoff or to channel flows. Straw dikes will also be used where appropriate to control runoff <br />and promote vegetation. <br />Other Methods. If corrective measures described under "No Defined Channel" fail, further observation will <br />be necessary to develop additional measures. A combination of the first two described methods or some • <br />variation will then be applied. Methods may include rode channels, contour furtows, or laterals with rock or <br />matting lined bottoms, V ditches made with a dozer or motor grader, and methods described above to <br />reestablish vegetation. <br />Head Cuttinc Stabilization. Head cutting will be controlled using several varying methods. If the area is at a <br />point that concentrates runoff, the area will be improved to accept the runoff. This would include reshaping <br />the channel and channel bottom, seeding, and covering the channel with erosion matting or rock. In other <br />areas, depending on the extent of erosion and time of year, disking and seeding will be conducted as <br />required. Straw bales, erosion matting and rock fill may also be used to stabilize the area. Straw mulching <br />and crimping will be considered as a further option. <br />SCC will submit to the Division by June 1 of each year, a copy of the map identifying the rill and gully areas <br />along with a rill and gully stabilization plan that briefly describes the problem at each identified area and The <br />proposed mitigative measures. The rill and gully stabilization plan will be implemented by July 1 of each <br />year and completed by November 1 or until weather conditions restrict operations. • <br />TR-37 13-28 Revised 04/05 <br />
