SITE. MAY REQUIRE PERIODIC
TOPDRESSING WITH 2"CH STONE.
2.IMMEDIATELY REMOVE ALL
OBJECTIONABLE MATERIALS
SPILLED, WASHED OR TRACKED
ONTO PUBLIC ROADWAYS..
CONSTRUCTION NOTES:
1.ENTRANCE(S) SHALL BE LOCATED TO PROVIDE MAXIMUM
UTILITY BY ALL CONSTRUCTION VEHICLES.
2.TURNING RADIUS SUFFICIENT TO ACCOMMODATE LARGE
TRUCKS SHALL TO BE PROVIDED.
3.ENTRANCES MUST BE MAINTAINED IN A CONDITION WHICH
WILL PREVENT TRACKING OR DIRECT FLOW OF MUD ONTO
STREETS. PERIODIC TOPDRESSING WITH STONE WILL BE
NECESSARY. CONTRACTOR SHALL MAINTAIN AS NECESSARY.
4.ANY MATERIAL WHICH STILL MAKES IT ONTO THE ROAD
MUST BE CLEANED UP IMMEDIATELY.

STORMWATER FLOW.
2.SEE SPECIFICATIONS FOR TEMP. LINING REQUIREMENTS.
3.PREPARE SOIL BEFORE INSTALLING MATS OR NETS, INCLUDING APPLICATION OF LIME,
FERTILIZER AND SEED.
4.BEGIN AT THE TOP OF THE CHANNEL BY ANCHORING THE NET OR MAT IN A 6" DEEP TRENCH.
BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
5.ROLL CENTER MAT OR NET IN DIRECTION OF WATER FLOW ON BOTTOM OF CHANNEL.
6.PLACE MAT OR NET END OVER END (SHINGLE STYLE) WITH A 6" OVERLAP. USE DOUBLE ROW
OF STAGGERED STAPLES 4" APART TO SECURE.
7.FULL LENGTH EDGE OF MAT OR NET AT TOP SIDE SLOPES SHALL BE ANCHORED IN 6" DEEP
TRENCH AFTER STAPLING.
8.MATS OR NETS SHALL BE OVERLAPPED 4" OVER THE CENTER BLANKET AND STAPLED.
9.THE TERMINAL END OF THE MAT OR NET MUST BE ANCHORED IN A 6" DEEP TRENCH. BACKFILL
AND COMPACT THE TRENCH AFTER STAPLING.
MAINTENANCE NOTES:
1.GRASSED-LINED CHANNELS TO BE
INSPECTED WEEKLY AND AFTER EVERY
RAINFALL EVENT, DURING THE
ESTABLISHMENT AND AFTER THE
ESTABLISHMENT PERIOD.
2.IF THE CHANNEL LINING BECOMES
DAMAGED, GULLIED OR WASHED OUT, IT
IS TO BE REPAIRED IMMEDIATELY WITH
NEW CHANNEL LINING AND REGRADING OF
THE CHANNEL IF NECESSARY.
3.REMOVE SEDIMENT ACCUMULATIONS TO
MAINTAIN DESIGNED CARRYING CAPACITY.
4.GRASS TO BE HEALTHY AND IN VIGOROUS

MAINTENANCE NOTES:
1.INSPECT COMPOST SOCKS WEEKLY AND AFTER EACH
SIGNIFICANT RAINFALL EVENT (1/2 INCH OR
GREATER).
2.REMOVE ACCUMULATED SEDIMENT AND ANY
DEBRIS. THE COMPOST SOCK MUST BE REPLACED IF
CLOGGED OR TORN.
3.IF PONDING BECOMES EXCESSIVE, THE SOCK MAY
NEED TO BE REPLACED WITH A LARGER DIAMETER
OR A DIFFERENT MEASURE.
4.THE SOCK NEEDS TO BE REINSTALLED IF
UNDERMINED OR DISLODGED.
5.THE COMPOST SOCK SHALL BE INSPECTED UNTIL
LAND DISTURBANCE IS COMPLETE AND THE AREA
ABOVE THE MEASURE HAS BEEN PERMANENTLY
STABILIZED.

2. REMOVE SEDIMENT AND RESTORE SEDIMENT STORAGE AREA TO ITS ORIGINAL DIMENSIONS WHEN SEDIMENT
HAS ACCUMULATED TO ONE-HALF THE DESIGN DEPTH OF THE TRAP.
3. CHECK THE STRUCTURE FOR DAMAGE AND REPLACE ANY DISPLACED RIPRAP IMMEDIATELY.
4. APPROPRIATELY STABILIZE ALL BARE AREAS AROUND THE INLET.

2.LOCATE REINFORCED OUTLET AT LOW POINTS OF SILT FENCE BARRIER.
3.PLACE RIP RAP WITH CARE. DO NOT TEAR SILT FENCE FABRIC.
MAINTENANCE NOTES:
1.REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE
ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE FENCE/OUTLET. TAKE CARE TO AVOID
UNDERMINING THE FENCE DURING CLEANOUT. REMOVE & REPLACE
STONE AS NECESSARY AS IT BECOMES CLOGGED WITH SEDIMENT.
2.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.
