CONSTRUCTION NOTES:
1. INSTALL GRADIENT CONTROL STRUCTURES IN THE RESTORED STREAM CHANNEL TO MATCH
GRADIENT BREAKS IN THE UNDISTURBED STREAM CHANNEL UPSTREAM OF THE CHANNEL SITE. LOGS, ROCK OR ROOTWADS CAN BE USED FOR GRADIENT CONTROL. INSTALL ROCKS AND ROOTWADS IN A
SLIGHTLY CONVEX SHAPE. LOGS SHALL HAVE A MINIMUM 12" SMALL END DIAMETER UNLESS OTHERWISE
APPROVED BY THE CONTRACTING OFFICER. ROCK SHALL MEET THE MINIMUM SIZE SHOWN ON THE
DRAWINGS AND BE DURABLE SO THAT IT REMAINS WHOLE AFTER INSTALLATION. ROCK CAN BE
CONSERVED FROM ADJACENT EXCAVATION. REMOVE ROOTWADS FROM A MINIMUM DIAMETER BREAST
HEIGHT (DBH) 16" TREE AND USE AS GRADIENT CONTROL.
2. ROCK CONSERVED FROM EXCAVATION CAN BE USED TO ARMOR THE STREAMBED. ARMOR ROCK
SIZE SHOULD MATCH THE THE DIMENSIONS OF THE ROCK IN THE ADJACENT UNDISTURBED CHANNEL.
3. INSTALL GRADIENT CONTROL STRUCTURES PERPENDICULAR TO STREAM FLOW WITH THE EXCEPTION
OF THE ROCK/LOG STRUCTURE.
4. KEY GRADIENT CONTROL STRUCTURES A MINIMUM OF 4" BELOW ORIGINAL STREAM GRADE AND BURY
HORIZONTALLY A MINIMUM OF 6 FEET INTO EACH STREAM BANK.
5. DITCH RELIEF CULVERTS DO NOT REQUIRE GRADIENT CONTROL STRUCTURES UNLESS THEY ARE IN A
NATURAL CHANNEL.
6. USE TREES AND LOGS STORED DURING THE CLEARING OPERATION AS HABITAT LOGS. INSTALL A
MINIMUM OF 5 LOGS WITH A MINIMUM LARGE END DIAMETER OF 10" AND A MINIMUM LENGTH OF 20'.
INSTALL HABITAT LOGS SO THEY CROSS THE STREAM CHANNEL AND PROVIDE SHADE AND COVER.

FROM ROAD CENTERLINE AND SLOPE THE DITCH FROM CUT BANK TO FILL
SLOPE TO FACILITATE DRAINAGE OF WATER OFF THE ROAD.
3. INTERCEPT DITCH WATER BY INCLUDING A DITCH BLOCK DURING CONSTRUCTION OF WATER BAR.
