REl'EGETAT?UN: R,evegetat:on of the disturoed areas will c.ccur in two <br />stages. The first stage will be the seeC:ng and establishiment of a <br />pere~n;al grass and 'orb cover us:r~g a seed m:•t_re appropriate to the <br />si*_e anc capable =` prod u,_ing fast and th.c F: growth. This, is <br />necessary to crr--ate a rapid protection of the site against erosion. <br />The seeC mir:ture to be used is as follows: <br />SNYDER ROADSIDE DISTURBANCES SEED MIXTURE <br />(Based on a Broadcast Pate) <br />---------------------------------------------------- <br />---------------------------------------------------- <br />SPECIES lb/acre seeds/lb seeds/sgft <br />INTERMEDIATE WHEAT.

Exper-~ence has <br />shown that delaying beyond that period of time results in a reduced <br />initial growth. Because it is expected the grading and soil placement <br />will occur during the fall and winter months, the seeding will be done <br />in the fall or winter. <br />The slopes t.o be seeded are north facing. Therefore., the use of <br />mulch would not only be unnecessary but undesirable. A mulch <br />encourages the accumulation of moisture in the soil which, if <br />excessive, can induce slumping. This was a very significant problem <br />on the Vail Pass highway protect where straw mulch was co~:ered with <br />~~ute net. This treatment on fail Pass even ineuced some ~jegree of <br />slumping on south facing slopes. Of course here the moisture received <br />is far less than is the case on Vail Pass, but the retention of <br />moisture can still be signif~can± and .educe instability in the slope <br />' mul r .5 t~s:-:,. <br />The mis:ture shown abov= .~ similar :n many respects to the <br />. lure that was app!:ed to the steep, north-`acing road =uts along <br />the Pikeview Quarry Road. That seeding has been highly successful <br />even though the parent material was the growth medium (no soil was <br />..sed) . <br /> <br />Faqe 5 of 8 SIJI'DER n^OAD CORRECTIVE ACTiUN PLAN <br />
