EROSION CONTROL MAINTENANCE SCHEDULE
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 OCCUR, 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 TOP DRESSING 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/SEDIMENT DITCH: INSPECT TEMPORARY DIVERSIONS/SILT DITCH ONCE A
WEEK AND AFTER EVERY RAINFALL. IMMEDIATELY REMOVE SEDIMENT FROM THE FLOW AREA AND
REPAIR THE DIVERSION 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.
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.
HARDWARE CLOTH & GRAVEL PIPE INLET PROTECTION: INSPECT THE FABRIC BARRIER AFTER
EACH RAIN AND MAKE REPAIRS AS NEEDED. REMOVE SEDIMENT FROM THE POOL AREA AS
NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN. TAKE CARE NOT TO
DAMAGE OR UNDERCUT THE FABRIC DURING SEDIMENT REMOVAL. WHEN THE CONTRIBUTING
DRAINAGE AREA HAS BEEN ADEQUATELY STABILIZED, REMOVE ALL MATERIALS AND ANY
UNSTABLE SEDIMENT AND DISPOSE OF THEM PROPERLY. BRING THE DISTURBED AREA TO THE
GRADE OF THE DROP INLET AND SMOOTH AND COMPACT IT. APPROPRIATELY STABILIZE ALL
BARE AREAS AROUND THE INLET.
TEMPORARY SEDIMENT TRAP: INSPECT TEMPORARY TRAPS AFTER EACH PERIOD OF SIGNIFICANT
RAINFALL. REMOVE SEDIMENT AND RESTORE THE TRAP TO ITS ORIGINAL DIMENSIONS WHEN THE
SEDIMENT HAS ACCUMULATED TO ONE—HALF THE DESIGN DEPTH OF THE TRAP. PLACE THE
SEDIMENT THAT IS REMOVED IN THE DESIGNATED DISPOSAL AREA AND REPLACE THE
CONTAMINATED PART OF THE GRAVEL FACING. CHECK THE STRUCTURE FOR DAMAGE FROM
EROSION OR PIPING. PERIODICALLY CHECK THE DEPTH OF THE SPILLWAY TO ENSURE IT IS A
MINIMUM OF 1.5 FT BELOW THE LOW POINT OF THE EMBANKMENT. IMMEDIATELY FILL ANY
SETTLEMENT OF THE EMBANKMENT TO SLIGHTLY ABOVE DESIGN GRADE. ANY RIP RAP DISPLACED
FROM THE SPILLWAY MUST BE REPLACED IMMEDIATELY. AFTER ALL SEDIMENT —PRODUCING AREAS
HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE AND ALL UNSTABLE SEDIMENT.
SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE PROPERLY.
SEDIMENT FENCE (SILT FENCE) INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND
AFTER EACH RAINFALL. MAKE ANY REQUIRED REPAIRS IMMEDIATELY. REMOVE SEDIMENT DEPOSITS
AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT.
REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO
GRADE AND STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY
STABILIZED.
SURFACE ROUGHENING: PERIODICALLY CHECK THE SEEDED SLOPES FOR RILLS AND WASHES.
FILL THESE AREAS SLIGHTLY ABOVE THE ORIGINAL GRADE, THEN RESEED AND MULCH AS SOON
AS POSSIBLE.
ROLLED EROSION CONTROL PRODUCTS: INSPECT PRODUCTS AT LEAST WEEKLY AND AFTER EACH
SIGNIFICANT (1/2 INCH OR GREATER) RAIN FALL EVENT REPAIR IMMEDIATELY. GOOD CONTACT
WITH THE GROUND MUST BE MAINTAINED, AND EROSION MUST NOT OCCUR BENEATH THE RECP.
ANY AREAS OF THE RECP THAT ARE DAMAGED OR NOT IN CLOSE CONTACT WITH THE GROUND
SHALL BE REPARIED AND STAPLED. IF EROSION OCCURS DUE TO POORLY CONTROLLED
DRAINAGE, THE PROBLEM SHALL BE FIXED AND ERODED AREA PROTECTED. MONITOR AND
REPAIR THE RECP AS NECESSARY UNTIL GROOUND COVER IS ESTABLISHED.
GRASS -LINED SWALES: MUST NOT BE SUBJECTED TO SEDIMENTATION FROM DISTURBED AREAS.
INSPECT SWALES AT REGULAR INTERVALS AS WELL AS AFTER MAJOR RAINS. AND MAKE REPAIRS
PROMPTLY. GIVE SPECIAL ATTENTIONS TO THE OUTLET AND INLET SECTIONS AND OTHER POINTS
WHERE CONCENTRATED FLOWS ENTERS. CAREFULLY CHECT STABILITY AT ROAD CROSSING, AND
LOOK FOR INDICATION OF PIPING, SCOUR HOLES AND BANK FAILURES. MAKE REPAIRS
IMMEDIATELY. MAINTAIN ALL VEGETATION ADJACENT TO THE SWALES IN A HEALTHY AND
VIGOROUS CONDITIONS TO PROTECT THE AREA FROM EROSION AND SCOUR DURING
OUT —OF —BANK FLOW.
TEMPORARY SEEDING: RESEED AND MULCH WHERE SEEDLING EMERGENCE IS POOR, OR WHERE
EROSION OCCURS, AS SOON AS POSSILBLE. DO NOT MOW. PROTECT FROM TRAFFIC AS SOON
AS POSSIBLE. REFER TO PAGE 6.10.4. 6.10.5 AND 6.10.6 FOR CORRECT SEEDING MIXTURE
PER CURRENT SEASONAL CONDITIONS.
PERMANENT SEEDING: INSPECT SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS
AND RESEEDINGS WITHIN THE SAME SEASON, IF POSSIBLE. VEGETATAION MUST BE FULLY
ESTABLISHED UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING.
DUST CONTROL: MAINTAIN DUST CONTROL MEASURES THROUGH DRY WEATHER PERIODS UNTIL
ALL DISTURBED AREAS HAVE BEEN STABILIZED.
