ALL BROKEN OR FRAYED ROOTS SHALL BE CUT OFF CLEANLY.H.THE DIAMETER OF THE PLANTING HOLES (PITS) FOR EACH PLANT SHOULD BE AT LEAST THREE TIMES THE DIAMETER OFTHE ROOT MASS. SCARIFY THE PLANTING PIT PRIOR TO EACH PLANT INSTALLATION.I.SET PLANTS UPRIGHT IN THE CENTER OF THE PIT. THE BOTTOM OF THE ROOT MASS SHOULD BE RESTING ONUNDISTURBED SOIL.J.PLACE BACKFILL AROUND BASE AND SIDES OF ROOT MASS, AND WORK EACH LAYER TO SETTLE BACKFILL AND TOELIMINATE VOIDS AND AIR POCKETS. WHEN PIT IS APPROXIMATELY 23 FULL, WATER THOROUGHLY BEFORE PLACINGREMAINDER OF THE BACKFILL. WATER AGAIN AFTER PLACING FINAL LAYER OF BACKFILL.CONTAINER STOCK / LIVE STAKESA.STOCK SHALL HAVE BEEN GROWN IN A CONTAINER LONG ENOUGH FOR THE ROOT SYSTEM TO HAVE DEVELOPEDSUFFICIENTLY TO HOLD ITS SOIL TOGETHER ONCE REMOVED FROM THE CONTAINER.B.CONTAINER PLANTS WILL NEED TO BE WATERED REGULARLY AND PLACED IN SHADY CONDITIONS UNTIL PLANTINGOCCURS.C.CUTTINGS SHOULD BE INSTALLED THE SAME DAY THEY ARE CUT. THE STAKE SHOULD BE ORIENTED WITH THE BUDSPOINTED UP, AND THE BOTTOM SHOULD BE CUT AT AN ANGLE FOR EASY INSERTION INTO THE GROUND.D.ABOUT FOUR-FIFTHS OF THE LENGTH OF THE STAKE SHOULD BE BELOW GROUND AND ANGLED DOWNSTREAM. AN IRONBAR CAN BE USED TO MAKE A PILOT HOLE TO PREVENT BARK FROM BEING DAMAGED DURING INSTALLATION.PLANT LOCATIONSA.NEW PLANTINGS SHALL BE LOCATED WHERE SHOWN ON PLAN EXCEPT WHERE CHANGES HAVE BEEN MADE BY THEPROJECT ENGINEER ONSITE.B.NECESSARY ADJUSTMENTS SHALL BE MADE ONLY AFTER APPROVED BY THE OWNER OR PROJECT ENGINEER.STREAMBANK AND BUFFER PLANTING SPECIFICATIONSLIVE STAKES AND CONTAINERIZED PLANTS - 8,000 FT2SCIENTIFIC NAMECOMMON NAMESIZE (CAL)SPACINGQTYLiriodendron tulipiferaTULIP POPLAR0.25" - 1.0"5 FT O.C.50Salix sericeaSILKY WILLOW0.50" - 1.0"5 FT O.C.50Platanus occidentalisSYCAMORE0.25" - 1.0"5 FT O.C.50Betula nigraRIVER BIRCH0.25" - 1.0"5 FT O.C.50Comus amomumSILKY DOGWOOD0.25" - 1.0"5 FT O.C.100PERMANENT SEEDING - 8,000 FT2SCIENTIFIC NAMECOMMON NAMETYPEAPP.

FLOWA'FLOW1.THE BOULDER CROSS-VANE IS A DESIGN FEATURE USED TO CONTROL GRADE IN HIGH IN GRADIENT REACHES ORAT CRITICAL JUNCTURES OF THE PROPOSED CHANNEL. THE CROSS-VANE IS ALSO USED TO PROVIDE ENERGYDISSIPATION, REDUCE NEAR BANK STRESS (NBS), AND CREATE A DIVERSITY OF AQUATIC HABITAT THROUGHSCOUR OF THE STREAM BED. THE CROSS-VANE IS COMPOSED OF A BOULDER SILL, WHICH IS A ROW OF BOULDERSSET AT AN ELEVATION PROVIDED IN THE PROPOSED PROFILE THAT SPANS PERPENDICULAR TO AND SLIGHTLYARCED ACROSS THE CHANNEL.
