OTHER SEEDED AREAS FOR EROSION AND SEDIMENTATION AFTER RUNOFF - PRODUCING RAINS. MAINTAIN
ALL VEGETATION IN A HEALTHY, VIGOROUS CONDITION. SEDIMENT - PRODUCING AREAS SHOULD BE TREATED
IMMEDIATELY.
CHECK DAM: INSPECT CHECK DAMS AND CHANNELS FOR DAMAGE AFTER EACH RUNOFF EVENT. ANTICIPATE
SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND EROSION FROM HIGH FLOWS AROUND THE
EDGES OF THE DAM. CORRECT ALL DAMAGE IMMEDIATELY IF SIGNIFICANT EROSION OCCURS BETWEEN
DAMS, INSTALL A PROTECTIVE RIP RAP LINER IN THAT PORTION OF THE CHANNELS. REMOVE SEDIMENT
ACCUMULATED BEHIND THE DAMS AS NEEDED TO PREVENT DAMAGE TO CHANNEL VEGETATION, ALLOW THE
CHANNEL TO DRAIN THROUGH THE STONE CHECK DAM, AND PREVENT LARGE FLOWS FROM CARRYING
SEDIMENT OVER THE DAM. ADD STONE TO DAMS AS NEEDED TO MAINTAIN DESIGN HEIGHT AND CROSS
SECTION.
DUST CONTROL: MAINTAIN DUST CONTROL MEASURES THROUGH DRY WEATHER PERIODS UNTIL ALL
DISTURBED AREAS HAVE BEEN STABILIZED.
SURFACE ROUGHENING: PERIODICALLY CHECK THE SEEDED SLOPES FOR RILLS AND WASHES. FILL THESE
AREAS SLIGHTLY ABOVE THE ORIGINAL GRADE, THEN RE -SEED AND MULCH AS SOON AS POSSIBLE.
LAND GRADING: PERIODICALLY CHECK ALL GRADED AREAS AND THE SUPPORTING EROSION AND
SEDIMENTATION CONTROL PRACTICES, ESPECIALLY AFTER HEAVY RAINFALLS. PROMPTLY REMOVE ALL
SEDIMENT FROM DIVERSIONS AND OTHER WATER - DISPOSAL PRACTICES. IF WASHOUT OR BREAKS OCCURS,
REPAIR THEM IMMEDIATELY. PROMPT MAINTENANCE OF SMALL ERODED AREAS BEFORE THEY BECOME
SIGNIFICANT GULLIES IS AN ESSENTIAL PART OF AN EFFECTIVE EROSION AND SEDIMENTATION CONTROL
PLAN.
TEMPORARY GRAVEL CONSTRUCTION ENTRANCE /EXIT: MAINTAIN THE GRAVEL PAD IN A CONDITION TO
PREVENT MUD OR SEDIMENT FROM LEAVING THE CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC
TOPDRESSING WITH 2 -INCH STONE. AFTER EACH RAINFALL, INSPECT ANY STRUCTURE USED TO TRAP
SEDIMENT AND CLEAN IT OUT AS NECESSARY. IMMEDIATELY REMOVE ALL OBJECTIONABLE MATERIALS
SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS.
TEMPORARY DIVERSIONS: INSPECT TEMPORARY DIVERSIONS ONCE A WEEK AND AFTER EVERY RAINFALL.
IMMEDIATELY REMOVE SEDIMENT FROM THE FLOW AREA AND REPAIR THE DIVERSIONS RIDGE. CAREFULLY
CHECK OUTLETS AND MAKE TIMELY REPAIRS AS NEEDED. WHEN THE AREA PROTECTED IS PERMANENTLY
STABILIZED, REMOVE THE RIDGE AND THE CHANNEL TO BLEND WITH THE NATURAL GROUND LEVEL AND
APPROPRIATELY STABILIZE IT.
ROLLED EROSION CONTROL PRODUCTS (CHANNEL MATTING):
INSPECT ROLLED EROSION CONTROL PRODUCTS AT LEAST WEEKLY AND AFTER
EACH SIGNIFICANT RAIN EVENT. REPAIR IMMEDIATELY. ANY AREAS OF THE MATTING THAT ARE DAMAGED
OR NOT IN CLOSE CONTACT WITH THE GROUND SHALL BE REPAIRED AND STAPLED. IF EROSION OCCURS
DUE TO POORLY CONTROLLED DRAINAGE, THE PROBLEM SHALL BE FIXED AND THE ERODED AREA
PROTECTED. MONITOR AND REPAIR THE MATTING AS NECESSARY UNTIL GROUND COVER IS ESTABLISHED.
TREE PRESERVATION AND PROTECTION:
REPAIR ANY DAMAGE TO PROTECTED TREE AS FOLLOWS:
SHOULD DAMAGE TO CROWN, TRUNK, OR ROOT SYSTEM OCCUR. REPAIR ROOTS BY CUTTING OFF THE
DAMAGED AREAS AND PAINTING THEM WITH TREE PAINT. SPREAD PEAT MOSS OR MOIST TOPSOIL OVER
EXPOSED ROOTS. REPAIR DAMAGE TO BARK BY TRIMMING AROUND THE DAMAGED AREAS, TAPER THE CUT
TO PROVIDE DRAINAGE, AND PAINT WITH TREE PAINT. CUT OFF ALL DAMAGED TREE LIMBS ABOVE THE
TREE COLLAR AT THE TRUNK OR MAIN BRANCH. USE THREE SEPARATED CUTS TO AVOID PEELING BARK
FROM HEALTHY AREAS OF THE TREE.
PERMANENT DIVERSIONS: INSPECT PERMANENT DIVERSIONS AFTER EVERY RAINFALL DURING THE
CONSTRUCTION OPERATION. IMMEDIATELY REMOVE ANY OBSTRUCTIONS FROM THE FLOW AREA AND REPAIR
THE DIVERSION RIDGE. CHECK OUTLETS AND MAKE TIMELY REPAIRS AS NEEDED. MAINTAIN THE
VEGETATION IN A VIGOROUS, HEALTHY CONDITION AT ALL TIMES.
DIVERSION DIKE (PERIMETER PROTECTION): INSPECT DIVERSION DIKES ONCE A WEEK AND AFTER EVERY
RAINFALL. IMMEDIATELY REMOVE SEDIMENT FROM THE FLOW AREA AND REPAIR THE DIKE.
OUTLET STABILIZATION STRUCTURE: INSPECT RIP RAP OUTLET STRUCTURES AFTER HEAVY RAINS TO SEE
IF ANY EROSION AROUND OR BELOW THE RIP RAP HAS TAKEN PLACE OR IF STONES HAVE BEEN DISLODGED.
IMMEDIATELY MAKE ALL NEEDED REPAIRS TO PREVENT FURTHER DAMAGE.
