Also any runeff that <br />cones off of the stoc};piled topsoil should be contained and <br />divert_d z~::ay for mud cree:•;, possible bac}; into the e>:istinq <br />grz:~el pit. The south rest corner of the property i= a:ell <br />Stilted a5 2ri stockpile area since is above znl• dra!nages 2nd <br />will not be Wined. Spreading of topsoil should not be done <br />~•r}len the topsoil is frozen, excessively wet or in z <br />condition that is difficult to work. F.fter the topsoil has <br />been replaced, final grading strould b= done to enable the <br />fields to be returned to irrigated pasture. Two o_` the <br />alternatives that nay be done is to either put the fields on <br />as close to an even grade as possible for their entire <br />length so that they can be irrigated with surface or <br />sprinkler irrigation, or to bench the field so that each <br />bench is either level or has a'slight grade. If the fields <br />are benchedtlie area where one bench slopes down to another <br />must be put on a gradual slope, such as 5:1, so that any <br />irrigation eauioment or firm machinery can pa=_s o;er tlieri <br />without difficulty. In areas where there will be a <br />substantial elevation change, such as were th=_ gravel pit <br />encounters zn existing fence, and farr,~~:~achinery will b=_ <br />used in this area a gradual slope of &:1 should be graded <br />in. <br />Since any runoff coming Eton the fields drains to the westOOO24 <br />into hlud Cre=_}; it will be important to control any runoff so <br />
