Based on this evaluation, several options wi 11 be available to correct the situation. These • <br />options will be a direct result of stutlying the situation and selecting the option that will <br />best rectify the erosional problem. One or more of the following options and corrective <br />methods will be employed. <br />Improved Channel. If it is determined that topography of the regraded area is such that <br />drainage is concentrated into a particular area, drainage control will be improved. The <br />drainage bottom or channel will be reshaped, if needed. This will be done with either a <br />motor grader or dozer, making the channel in the shape of a V that is approximately 16 feet <br />to 20 feet wide. The channel bottom wi 11 either be seeded, covered with erosion matting and <br />seeded, or rocked. The method used will depend on site conditions. The area will continue <br />to be observed for problems or necessary maintenance. <br />No Defined Channel. On a slope where there is no Swale or defined channel, a number of <br />operations may be performed, depending on the extent of the erosion. The area will be <br />disked on the contour or erosion matting will be placed on the azea, depending again on site <br />characteristics. Reseeding will then take place. In addition to the above, contour fuzrows <br />in and above the erosion area may be constructed to intercept and slow down the runoff oz to <br />channel flows. Straw dikes will also be used where appropriate to control runoff and <br />promote vegetation. <br />Other Methods. If corrective measures described undez "NO Defined Channel" fail, further <br />observation will be necessary to develop additional measures. A combination of the first <br />two described methods or some variation will then be applied. Methods may include rack <br />channels, contour furrows, or laterals with rock or matting bottoms, V ditches made with the <br />dozer or motor grader, and methods described above to reestablish vegetation. <br />Head Cutting Stabilization. Head cutting will be controlled using several, varying methods. <br />If the area is at a point that concentrates runoff, the area will be improved to accept the <br />runoff. This would include reshaping the channel and channel bottom, seeding, and covering <br />the channel with erosion matting or rocking. In other areas, depending on the extent of <br />erosion and time of year, disking and seeding will be conducted as required. Straw bales, <br />erosion matting and rock fill may also be used to stabilize the area. <br />A copy of the map identifying the rill and gully areas along with a rill and gully • <br />stabilization plan that briefly describes the problem at each identified area and the <br />8 <br />
