1. CONSTRUCT STREAM CROSSING WHEN FLOW IS LOW.
2. HAVE ALL NECESSARY MATERIALS AND EQUIPMENT
ON-SITE BEFORE WORK BEGINS. PRELIMINARY PLANS 3. MINIMIZE CLEARING AND EXCAVATION OF STREAMBANKS. DO NOT usE FOR CONSTRUCTION
TYPICAL RIFFLE DO NOT EXCAVATE CHANNEL BOTTOM. COMPLETE ONE
SIDE BEFORE STARTING ON THE OTHER SIDE. 4. INSTALL STREAM CROSSING AT RIGHT ANGLE TO THE FLOW.
5. GRADE SLOPES TO A 2:1 SLOPE. TRANSPLANT SOD
FROM ORIGINAL STREAMBANK ONTO SIDE SLOPES. 6. MAINTAIN CROSSING SO THAT RUNOFF IN THE
CONSTRUCTION ROAD DOES NOT ENTER EXISTING CHANNEL.
Wbkf EXISTING GROUND 7. A STABILIZED PAD OF CLASS "A" STONE, 6 INCHES THICK, LINED WITH TYPE 2 FILTER FABRIC SHALL BE,
USED OVER THE BERM AND ACCESS SLOPES.

~ THE WATER AWAY FROM THE BANK. A TRANSPLANT OR BOULDER SHOULD
BASEFLOW 10-15 FEET LONG BE PLACED ON THE DOWNSTREAM SIDE OF THE ROOT WAD IF A BACK EDDY

TRENCHING METHOD:
IF THE ROOT WAD CANNOT BE DRIVEN INTO THE BANK OR THE BANK NEEDS
_ ~ - - TO BE RECONSTRUCTED, THE TRENCHING METHOD SHOULD BE USED. THIS
FOOTER LOG > 12" DIAMETER METHOD REQUIRES THAT A TRENCH BE EXCAVATED FOR THE LOG BOULDER PORTION OF THE ROOT WAD. IN THIS CASE, A FOOTER LOG SHOULD BE
INSTALLED BELOW STREAM BED INSTALLED UNDERNEATH THE ROOT WAD IN A TRENCH EXCAVATED PARALLEL
ROOTWADOROSS-SECTION PLAN TO THE BANK AND WELL BELOW THE STREAMBED.ONE-THIRD OF THE ROOT WAD SHOULD REMAIN BELOW NORMAL BASE FLOW CONDITIONS.
