Compact any fill required in the subgrade to o density opproximoting thot of the surrounding undisturbed moteriol or overf7/l depressions With riprop. Remove brush, trees, stumps ond other ob� /'ectionol material. Cut the subgrode sufflciently deep that the finlshed grode of the riprop Will be at the elevotion of the surrounding area. Channels sh�ould be excavated sufficiently to alloW placement of the �iprap in o manner such that the finished inslde dlmens7ons and grode of the riprop meet deslgn specificotions. Sand and grovel filter blanket - Ploce th�e filter blanket immediately after the ground foundotion is prepared. For gravel, spread filter stone in o uniform layer to th�e specified depth. Where more than one loyer of filter material is used, spread the loyers With minimal mixing. Synthetic filter fabric - Ploce the cloth filter directly on the prepared foundotion. Overlap tl� edges by at least l2 inches, and space anchor pins every 3 ft along the overlap. Bury the upstream end of the cloth a minimum of l2 inches beloW ground and Wl�re necessory, bury the loWer end of the cloth or overlop With the next section as required.

Ploce riprap to its full thickness In one operation. Do not ploce riprop by dumping through chutes or other methods that cause segregotion of stone slzes. Take care not to dislodge the underlying base or f1/ter When placing the stones. The finished slope should be free of pockets of small stone or clusters of lorge stones.
