UPSLOPE FROM THE CURB INLET, LAY THE BAGS TIGHTLY END TO END IN A ROW CURVING FROM THE CURB AND AWAY FROM THE INLET. 3. OVERLAP THE BARRIER ONTO THE CURB, AND EXTEND IT A MINIMUM OF 3 FT. INTO THE STREET TO INTERCEPT THE RUNOFF. 4. IF USING MORE THAN ONE ROW, OVERLAP THE BAGS WITH THE ROW BENEATH, AND LEAVE A ONE -BAG GAP IN THE MIDDLE OF THE TOP ROW TO SERVE AS A SPILLWAY. 5. FOR ADDITIONAL STORAGE CAPACITY, CONTRUCT A SERIES OF SANDBAG BARRIERS ALONG THE CURB SO EACH ONE TRAPS SMALL AMOUNTS OF SEDIMENT. 6. PLACE SILT FENCE ONE FOOT BEHIND INLET. SEE DETAIL EC -2 FOR INSTALLATION. 7. IF INLET IS NOT LOCATED IN A SADDLE, THE BAGS ON THE DOWNSLOPE SIDE OF THE INLET ARE NOT REQUIRED. MAINTENANCE 1.
