The foundot�on sholl be over-excavoted so that ot least 8�� of the focinq rock or rock is buried below finol grode. 2.2 Install the droin p�pes os shown on the drowinys. 2.3 Re�nforced zone ond retoined zone bockfill sholl be ploced in lifts no thicker thon 8". Backfill shall be ploced in horizontol loyers ond compocted aqainst horizontol surfoces. Only hand-operoted compoction equipment sholl be used within 3' of the back of the focing of woll. Bockfiil should be ploced ond compocted sequentiolly from the foce oF woll to the bock of the geogrid reinforcements to aid in geogrid tension�ng. 2.4 Re�nforced zone and retoined zone bockfill sholl be compocted to ot least 95% of maximum dry density os determ�ned by the stondord Proctor (AA$HTO T-99) ot opt�mum mo�sture content t2�. 2.5 Place geogrid reinforcements os shown on the drpwings. 2.6 Geogrid re�nforcement length os shown on the drowings is meosured from the face of woll to the back of the geogrid. 2.7 Trock veh�cles sholl not be operoted d�rectly on the geogr�ds. A m�n�mum of 6" of backf�ll �s requ�red to operote trock veh�chles over geogr�ds and turn�ng shoil be m�n�mized to ovoid displocing the geogr�ds. 2.8 Rubber-tired vehicles moy drive slowly directly on the geogrids if necessory. 2.9 Geogrid reinforcements shall be placed with the machine d�rect�on perpendiculor to the woll foce. 2.10 In convex woll curves, overloppinq geoqrids may be placed if ot least 2�� of bockfill is ploced between overlopping geogrids. 2.11 Permanent surfoce ond irr�gation woter diversion �s the respons�bility of the owner.
