This is a minimum recommendation. Additional quantities of organic material may be <br />beneficial. Viable organic materials could include peat, composts, or rotted manure. <br />Until vegetation is more permanently established on the 5.4 acres, the Division <br />believes additional erosion control measures, in addition to contour furrows, are <br />necessary. Adequately anchored mulches, bonded fiber matrixes, fiber blankets, soil <br />tackifiers, or netting, used alone or in combination, may provide the necessary erosion <br />control to allow interseeded vegetation to become established. Considering the size <br />of the site (5.4 acres), any soil stabilization treatment should be designed to last until <br />the second growing season after interseeding. <br />4. Please support the values used for cover (50%), cover factor (.07), and practice factor <br />(.80) in the sediment yield calculations. The Division anticipates that these values <br />were derived, in part, from information collected during the 1999 vegetation survey <br />and soil sampling. <br />If you have any questions, please contact me. <br />Sin ely, <br />z~c ~ <br />K t A.
