THE CONTRACTOR IS RESPONSIBLE FOR PROVIDING A SYSTEM WHICH CONVEYS THE DRAINAGE TEMPORARILY IN ACCORDANCE WITH THIS PLAN, OR THROUGH USE OF AN ALTERNATIVE METHOD THAT PREVENTS EROSION AND SEDIMENTATION AND DISSIPATES RUNOFF ENERGY PRIOR TO REACHING THE EXISTING WETLANDS. THE

EXISTING 12" RCP POWDER MILL ROAD MILL POWDER CONTRACTOR SHALL SUBMIT A TEMPORARY DRAINAGE DIVERSION PLAN FOR APPROVAL BY THE ENGINEER AND THE DRAINAGE PIPE CONCORD NATURAL RESOURCES COMMISSION.
