<br />REVEG~TATION GUIDCLINF.:, <br />1. lifter earth disturbance operations the following steps are needed: <br />A. ride slopes should be flatter than ?:1. Slopes of h:l or <br />flatter are much mare desirable for greater success in <br />re-establishment of vegetation and operation of equipment. <br />B. Excess water from adjacent areas should not he allowed to <br />flow onto the area unless erasion control oractires are <br />implemented. <br />C. Length of slope should be properly controlled to prevent <br />erosion. <br />D. Topsoil is needed on sites having e-.cposed soil surfaces <br />low in organic naterial and texture classification of <br />clay loam or heavier. This need increases significantly <br />if the soils are inherently dry, if the slopes are <br />greater than 6:1 and if the slope aspect is south or <br />southwest. Topsoil should be applied after shaping and tilled <br />to a depth of G inches binding topsoil to existing soil. <br />2. Fertilization <br />A. Fertilizer of not less than 40 lbs, nitrogen and 40 lbs. <br />phosphorous should be applied unless a soil analysis indicates <br />sufficient amounts of these elements. Application of <br />fertilizers should be i~unediately prior to or at the time <br />of seeding. <br />3. Seedbed Preperation <br />A. The seedbed should be prepared immediately following all <br />earth moving operations prescribed in the engineering and <br />landscape de:;ign. <br />i3. All rocks, trash and other debris that will interfere with <br />seedi.nr, should be removed. Till the ground tc a depth of <br />4 to `~ inches. If the seedbed is prepared immediately <br />follusring construction this operation can usually be omitted, <br />exceo'. on fresh r:ut areas that have nut otherwise been <br />disturbed. Apply fer~ilizer, seed and mulch, if needed. <br />4. r;~.,l:hing <br />A. .; mulch may be needed to conserve moisture, prevent <br />rrusting, reduce runoff and erosion anal help establish <br />a plcutt cover. <br />9, h7ul.r•.hing ^~iteri^i shuuld be applied inr..ediately before or <br />C. 1•:ithur :mu ul' tlr•~ mulching, i~ietYlrid:, li:a.ed bcluw wuuld be <br />acceptable. <br />
