BOULDER WALL NOTES TMI$WORK CONSISTS OF CONSTRU[TING BOULDER WALL STHUCTURES. BOULDER WALLS ARE FORMED OF INTEHLOCRING,DRY-$TACKED ROCM1$WITMOUT REINFORCING STEEL.MORTAR,OR CON[RETE.

GENERAL'.THE FOLLOWING DEFINITIONS APPLY TO BOULOER WALL CONSTAIJCTION: (AJ BASE ROCM1�.THE BASE ROCK IS THE LOWERMOST ROCK IN TME BOUL�ER WALL.AND BEARS OIqECtLY ON TNE SOIL SIBGRADE.

BOULDER WALL GONSTRUCTION: (A)BOUL�ER WALL FOUNUATION E%fAVATION: EX[AVATE A F�UNDATION TRENCH AT LEAST 6 INCHES BELOW THE EXPOSED BOTTOM OF THE WALL.RUNNING TNE FULL LENGTH OF THE PItOPOSED BOUIDER WALL.DEEPEP EMBEDMENT MAY BE REOUIFEO WMEftE A TOE SIOPE IS PRESENT. E%CAVATE iHE FWNOATION TO A MINIMUM WIDTH EOUAL TO THE SPECIFIED BASE ROCR WIDTH. E%ERCISE CARE DURING EXCAVATION SO AS NDT TO UNDERMINE THE GARAGE FOUNDRTION. STABILITY OF TEMPORARY CUT SLOPES IS THE RESPoNSIBILItY OF THE CONTRACTOR. (B)BOULDER PLACEMENT: PLACE TME FIRST[OURSE OF ROCK(BASE RO[K)ON FIRM,UNYIELDING SOIL WITH FIILL CONTACT BETWEEN THE RO[R AND THE SUBGNADE.
