REVISIONS' REV. DESCRIPTION BY DATE SHEET 1 SHEET 1 OF 2 TEMPORARY EROSION AND SEDIMENT CONTROL GENERAL NOTES' 1. SHOULD THE TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHOWN ON THESE PLANS PROVE TO BE INADEQUATE DURING CONSTRUCTION, THE CONTRACTOR SHALL INSTALL ADDITIONAL EROSION AND SEDIMENT CONTROL FACD_ITIES. 2. ALL EROSION AND SEDIMENT CONTROL FACILITIES AND DEVICES SHALL BE INSPECTED DAILY AND IMMEDIATELY MAINTAINED, IF NECESSARY. 3. ALL TEMPORARY EROSION AND SEDIMENT CONTROL FACILITIES AND DEVICES SHALL BE LEFT IN PLACE UNTIL THE UPSLOPE AREAS HAVE BEEN PERMANENTLY STABILIZED. 4. THIS PROJECT SHALL COMPLY WITH THE EROSION AND SEDIMENT CONTROL REQUIREMENTS, WHERE APPLICABLE, IN THE STDRMWATER MANAGEMENT MANUAL FOR WESTERN WASHINGTON BY THE WASHINGTON STATE DEPARTMENT OF OF ECOLOGY. 5, PLASTIC COVERING OVER THE EXPOSED FILL SLOPE MAY BE UTILIZED IN LIEU OF SILT FENCING, IF NECESSARY. PLASTIC COVERING SHALL EXTEND BEYOND THE FILL SLOPE IF CROSS-SECTION DRAINAGE HAS NOT BEEN ESTABLISHED, 6. THE STABILIZED CONSTRUCTION ENTRANCE, TEMPORARY SEDIMENT PONDS AND SILT FENCING (IF NEEDED) SHALL BE INSTALLED PRIOR TO OR AS THE FIRST STAGE OF PROJECT CONSTRUCTION. OTHER SEDIMENT CONTROL MEASURES SUCH AS SEDIMENT TRAPS, BARRIERS AND OTHER BMP's SHALL BE CONSTRUCTED AS NECESSARY. 7. THE CONTRACTOR SHALL PROVIDE DUST CONTROL, IF NECESSARY, DURING THE ENTIRE CONSTRUCTION PROCESS. 8, SEDIMENTS FROM THE CONSTRUCTION SITE THAT IS TRACKED ONTO PUBLIC ROADWAYS SHALL BE REMOVED AND CLEANED IMMEDIATELY, AND THOROUGHLY CLEANED AT THE END OF EACH DAY DURING CONSTRUCTION. WASHING SHALL NOT BE DONE. STABILIZED CONSTRUCTION ENTRANCE 1. TEMPORARY STABILIZED CONSTRUCTION INGRESS/ EGRESS SHALL BE LIMITED TO ONE LOCATION, IF POSSIBLE, AND BE CONSTRUCTED PER THE 'STABILIZED CONSTRUCTION ENTRANCE' DETAIL ON THIS SHEET. ADDITIONAL ROCK SHALL BE ADDED PERIODICALLY TO MAINTAIN PROPER FUNCTION OF THE PAD, 2. THE WIDTH OF THE TEMPORARY CONSTRUCTION ENTRANCE SHALL BE A MINIMUM OF 20 FEET WIDE WITH A 25 FT RADIUS, HOWEVER, THIS AREA SHALL BE INCREASED IF NECESSARY TO ACCOMODATE CONSTRUCTION EQUIPMENT ENTERING AND LEAVING THE CONSTRUCTION SITE. 3. IF THE STABILIZED CONSTRUCTION ENTRANCE PAD DOES NOT ADEQUATELY REMOVE MUD FROM THE VEHICLE WHEELS, TEE WHEELS SHALL BE HOSED OFF BEFORE LEAVING THE PROJECT SITE THE WASHING SHALL BE COMPLETED OVER QUARRY SPALLS OR CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR SILT FENCE. SILT FENCE 1, FILTER FABRIC SHALL BE PURCHASED IN A CONTINUOUS ROLL AND CUT TO THE LENGTH OF THE BARRIER TO AVOID USE OF JOINTS. WHEN JOINTS ARE NECESSARY, FILTER CLOTH SHALL BE SPLICED TOGETHER ONLY AT A SUPPORT POST, WITH A MINIMUM 6-INCH OVERLAP, AND SECURELY FASTENED AT BOTH ENDS TO THE POST. 2. POSTS SHALL BE SPACED A MAXIMUM OF 6 FEET APART AND DRIVEN SECURELY INTO THE GROUND (MINIMUM OF 30 INCHES). 3, A TRENCH SHALL BE EXCAVATED APPROXIMATELY 8 INCHES WIDE AND 12 INCHES DEEP ALONG THE LINE OF POSTS AND UPSLOPE FROM THE BARRIER, THIS TRENCH SHALL BE BACKFILLED WITH WASHED GRAVEL. 4. WHEN STANDARD STRENGTH FILTER FABRIC IS USED, A WIRE MESH SUPPORT FENCE SHALL BE FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS USING HEAVY DUTY WIRE STAPLES AT LEAST 1 INCH LONG, TIE WIRES OR HOG RINGS. THE WIRE SHALL EXTEND INTO THE TRENCH A MINIMUM OF 4 INCHES AND SHALL NOT EXTEND MORE THAN 24 INCHES ABOVE THE ORIGINAL GROUND SURFACE. 5. THE STANDARD STRENGTH FILTER FABRIC SHALL BE STAPLED OR WIRED TO THE FENCE, AND 20 INCHES OF THE FABRIC SHALL BE EXTENDED INTO THE TRENCH. THE FABRIC SHALL NOT EXTEND MORE THAN 24 INCHES ABOVE THE ORIGINAL GROUND SURFACE. FILTER FABRIC SHALL NOT BE STAPLED TO EXISTING TREES. 6. WHEN EXTRA -STRENGTH FILTER FABRIC (M DNOFILAMENT), AND CLOSER POST SPACING IS USED, THE WIRE MESH SUPPORT FENCE MAY BE ELIMINATED. IN SUCH A CASE, THE FILTER FABRIC IS STAPLED OR WIRED DIRECTLY TO THE POSTS WITH ALL OTHER PROVISIONS OF ABOVE NOTES APPLYING. 7. FILTER FABRIC FENCES SHALL NOT BE REMOVED BEFORE THE UPSLDPE AREA HAS BEEN PERMANENTLY STABILIZED. �. FILTER FABRIC FENCES SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING RDLONGED RAINFALL. ANY REQUIRED REPAIRS SHALL BE MADE IMMEDIATELY. 9, SILT FENCES WILL BE INSTALLED PARALLEL TO ANY SLOPE CONTOURS. 10. CONTRIBUTING LENGTH TO FENCE WILL NOT BE GREATER THAN 100 FEET. IL DO NOT INSTALL BELOW AN OUTLET PIPE OR WEIR. 12. INSTALL DOWNSLOPE OF EXPOSED AREAS. 13. DO NOT DRIVE OVER OR FILL OVER SILT FENCES, STOCKPILE MANAGEMENT 1. STOCKPILE SHALL BE STABILIZED (WITH PLASTIC COVERING OR OTHER APPROVED DEVICE) DAILY BETWEEN NOVEMBER 1 AND MARCH 31. 2. IN ANY SEASON, SEDIMENT LEACHING FROM STOCK PILES MUST BE PREVENTED. 3. TOPSOIL SHALL NOT BE PLACED WHILE IN A FROZEN OR MUDDY CONDITION, WHEN THE SUBGRADE IS EXCESSIVELY WET, OR WHEN CONDITIONS EXIST THAT MAY OTHERWISE BE DETRIMENTAL TO PROPER GRADING OR PROPOSED SODDING OR SEEDING. SEEDING FOR RAW SLOPES 1. SEEDING SHOULD BE DONE IMMEDIATELY AFTER FINAL SHAPING, EXCEPT DURING THE PERIOD OF NOVEMBER 1 THROUGH MARCH 1, WHEN THE SITE SHOULD BE PROTECTED BY MULCHING OR PLASTIC COVERING UNTIL THE NEXT SEEDING PERIOD. 2. BEFORE SEEDING, INSTALL NEEDED SURFACE RUNOFF CONTROL MEASURES SUCH AS GRADIENT TERRACES, INTERCEPTOR DIKES, SWALES, LEVEL SPREADERS AND SEDIMENT BASINS. 3, THE SEED BED SHALL BE FIRM WITH FAIRLY FINE SURFACE, FOLLOWING SURFACE ROUGHENING. PERFORM ALL OPERATIONS ACCROSS OR PERPENDICULAR TO THE SLOPE. 4. SEEDING MIXTURE SHALL BE AS SHOWN BELOW, AND SHALL BE APPLIED AT THE RATE OF 120 POUNDS PER ACRE. 5. SEED BEDS PLANTED BETWEEN MAY 1 AND OCTOBER 31 WILL REQUIRE IRRIGATION AND OTHER MAINTENANCE AS NECESSARY TO FOSTER AND PROTECT THE ROOT STRUCTURE. 6. SEED BEDS PLANTED BETWEEN NOVEMBER 1 AND APRIL 30, ARMORING OF THE SEED BED WILL BE NECESSARY, (e.g., GEDTEXTILES, JUTE MAT, CLEAR PLASTIC COVERING). 7. FERTILIZERS ARE TO BE USED ACCORDING TO SUPPLIERS' RECOMMENDATIONS. AMOUNTS SHOULD BE MINIMIZED, ESPECIALLY ADJACENT TO WATER BODIES AND WETLANDS. USE THE FOLLOWING RECOMMENDED SEED MIXTURE FOR EROSION CONTROL, OR A MASON COUNTY APPROVED ALTERNATE SEED MIXTURE.
