PURPOSE: REDUCES THE AMOUNT OF DEBRIS TRANSPORTED ONTO PUBLIC ROADS FROM CONSTRUCTION EQUIPMENT BY ACTION OF VEHICLE TIRES TRAVEUNG OVER GRAVEL PAD REMOVING MOST MUD AND DEBRIS FROM TIRES. DESIGN CRITERIA/SPECIFICATIONS: DESIGN: (1) SEE DETAIL 2-C-1, (2) STABILIZED CONSTRUCTION ENTRANCES SHOULD BE LOCATED WHEREVER VEHICLE ACCESS ROUTES INTERSECT PAVED ROADS; (3) MATERIAL SHOULD BE QUARRY SPALLS, 4" - 8" SIZE; (4) THE ROCK PAD SHOULD BE AT EAST 12-INCHES THICK AND 100 FEET IN LENGTH. LENGTH MAY BE REDUCED TO 50-FEET FOR SITES WITH MINOR GRADING (LESS THAN 1 ACRE OF EXPOSED SOIL); (5) WIDTH SHOULD BE THE FULL WIDTH OF THE VEHICLE INGRESS AND EGRESS AREA. MINIMUM WIDTH SHOULD BE 20-FEET. ADDITIONAL SUBGRADE STABILIZATION SUCH AS A GEOTEXTILE MAT MAY BE REQUIRED. PROCEDURE: (1) A FILTER FABRIC FENCE SHOULD BE INSTALLED DOWNHILL FROM THE CONSTRUCTION ENTRANCE TO INTERCEPT AND CONTAIN ANY SEDIMENT -LADEN RUNOFF FROM THE ENTRANCE OR FROM TIRE WASHING; (2) IF THE ROCK PAD DOES NOT ADEQUATELY REMOVE THE MUD FROM VEHICLE WHEELS, THE WHEELS SHOULD BE HOSED OFF BEFORE THE VEHICLE ENTERS A PAVED STREET. THE WASHING SHOULD BE DONE ON AN AREA COVERED WITH CRUSHED ROCK AND WAS WATER SHOULD DRAIN TO A SEDIMENT RETENTION FACILITY; (3) STREET CLEANING EQUIPMENT SHOULD BE AVAILABLE AS REQUIRED. MAINTENANCE: (1) ENTRANCES MAY REQUIRE PERIODIC TOP DRESSING WITH 2-INCH STONE, AS NECESSARY TO PREVENT TRACKING OR FLOW OF MUD ONTO PUBLIC ROADWAYS; (2) IF SEDIMENT IS TRANSPORTED ONTO A ROAD SURFACE, THE ROADS SHALL BE CLEANED THOROUGHLY AS A MINIMUM AT THE END OF EACH DAY. SEDIMENT SHOULD BE REMOVED FROM ROADS BY SHOVELING OR SWEEPING. STREET WASHING SHOULD TAKE PLACE ONLY AFTER SEDIMENT HAS BEEN REMOVED AS DESCRIBED ABOVE; (3) ANY ROCK SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY. CONTROL MEASURE: CONSTRUCTION ROAD STABILIZATION. PURPOSE: TEMPORARILY STABILIZES ROADS, PARKING AREAS, AND ON -SITE TRANSPORTATION ROUTES WITH STONE IMMEDIATELY AFTER GRADING, REDUCES EROSION CAUSED BY CONSTRUCTION TRAFFIC OR RUNOFF. DESIGN CRITERIA/SPECIFICATIONS: DESIGN: (1) PROVIDE ROCK STABILIZATION WHEREVER THERE IS THE POTENTIAL FOR EROSION OF TEMPORARY CONSTRUCTION ROUTES BY CONSTRUCTION TRAFFIC DURING WET WEATHER; (2) ROCK STABIUZATION MAY BE UNNECESSARY WHERE SOILS ON SITE ARE GRAVELLY; (3) A 6-INCH DEPTH OF 2" - 4" CRUSHED ROCK, GRAVEL BASE, OR CRUSHED SURFACING BASE COURSE SHALL BE APPLIED IMMEDIATELY AFTER GRADING OR THE COMPLETION OF UTILITY INSTALLATION WITHIN THE RIGHT-OF-WAY. A 3-INCH COURSE OF ASPHALT TREATED BASE (ATM) MAY BE USED INSTEAD OF THE CRUSHED ROCK. PROCEEDURE: (1) WHERE FEASIBLE, ALTERNATIVE ROUTES SHOULD BE MADE FOR CONSTRUCTION TRAFFIC; ONE FOR USE IN DRY CONDITION, THE OTHER FOR WET CONDITIONS WHICH INCORPORATES THE MEASURE LISTED BELOW; (2) TEMPORARY ROADS SHOULD FOLLOW THE CONTOUR OF THE NATURAL TERRAIN TO THE EXTENT POSSIBLE. SLOPE SHOULD NOT EXCEED 15 PERCENT. ROADWAYS SHOULD BE CAREFULLY GRADED TO DRAIN TRANSVERSELY. PROVIDE DRAINAGE SWALES ON EACH SIDE OF THE ROADWAY IN THE CASE OF A CROWNED SECTION, OR ONE SIDE IN THE CASE OF A SUPER ELEVATED SECTION. (3) INSTALLED INLETS SHALL BE PROTECTED TO PREVENT SEDIMENT LADEN RUNOFF FROM ENTERING THE STORM SYSTEM (SEE BMP'S ON FILTER INLET BARRIERS). MAINTENANCE: INSPECT STABILIZED AREAS REGULARLY, ESPECIALLY AFTER LARGE STORM EVENTS. ADD CRUSHED ROCK IF NECESSARY AND RE -STABILIZE ANY AREAS FOUND TO BE ERODING. CONTROL MEASURE: DUST CONTROL. PURPOSE: PREVENTS SURFACE AND AIR MOVEMENT OF DUST FROM EXPOSED SOIL SURFACES. DESIGN CRITERIA/SPECIFICATIONS: (1) MINIMIZE THE PERIOD OF SOIL EXPOSURE THROUGH USE OF TEMPORARY GROUND COVER AND OTHER TEMPORARY STABILIZATION PRACTICES. (SEE BARE GROUND BMP'S) (2) SITE SHOULD BE SPRINKLED WITH WATER UNTIL SURFACE IS WET. REPEAT AS NEEDED. TO PREVENT CARRYOUT OF MUD ONTO STREET, REFER TO STABILIZED CONSTRUCTION ENTRANCE BMP IN THIS SECTION. (3) SPRAY EXPOSED SOIL AREAS WITH AN APPROPRIATE DUST PALLIATIVE. NOTE: OIL IS PROHIBITED FOR USE AS A PALLIATIVE. CONTROL MEASURE: LIMIT CLEARING OF SITE. PURPOSE: REDUCES LIKEUHOOD OF, OR EXTENT OF, TURBIDITY IN DOWNSTREAM STORMWATER BY MINIMIZING THE SOURCE OF SILT PICKED UP ON SURFACE RUNOFF. DESIGN CRITERIA/SPECIFICATIONS: CLEARING SHOULD BE LIMITED TO THE MINIMUM AREA NECESSARY TO PERFORM WORK AND IMMEDIATELY REVEGETATE CLEARED AREAS. WHEN POSSIBLE, CONSTRUCTION SHOULD BE PLANNED IN STAGES, AND ONLY THE STAGE BEING WORKED ON SHOULD BE CLEARED. ONCE WORK IS COMPLETED, A GIVEN STAGE OF CONSTRUCTION SHOULD BE IMMEDIATELY REVEGETATED OR OTHERWISE STABIUZED. CONTROL MEASURE: COVER AREAS LEFT UNWORKED FOR MORE THAN 48 HOURS. (SEE ALSO MULCHING, SODDING, PLASTIC SHEETING BMP'S). PURPOSE: MINIMIZE THE AREA EXPOSED TO RAINFALL AND SURFACE RUNOFF, THEREBY REDUCING THE AMOUNT OF EROSION OF BARE GROUND AND THE AMOUNT OF SEDIMENT THAT MIGHT COLLECT IN SEDIMENTATION CONTROL STRUCTURES, SUCH AS SEDIMENT PONDS OR SILT FENCES. DESIGN CRITERIA/SPECIFICATIONS: DURING THE TIME PERIOD OF OCTOBER 1 THROUGH APRIL 30, AND AT OTHER TIMES OF THE YEAR WHEN THERE ARE EXTENDED PERIODS OF INCLEMENT WEATHER, ALL PROJECT -DISTURBED SOIL AREAS THAT ARE TO BE LEFT UNWORKED FOR MORE THAN 48 HOURS SHOULD BE COVERED BY MULCH, SODDING, OR PLASTIC COVERING. THIS PROCEDURE IS BASED ON THE INCREASED POTENTIAL FOR, AND CONSEQUENCES OF, FAILURE OF EROSION AND SEDIMENTATION CONTROL STRUCTURES DURING THIS PERIOD OF HIGH PRECIPITATION AND THE ASSUMPTION THAT AREAS NOT BEING WORKED ARE LIKELY TO BE LEFT UNATTENDED. CONTROL MEASURE: MULCHING. (SEE ALSO NETS AND MATS). PURPOSE: MULCHING PROVIDES IMMEDIATE TEMPORARY PROTECTION TO EXPOSED AREAS AND ALLOWS GERMINATION AND PROTECTION OF SEEDED AREAS BY CONSERVING MOISTURE, MODERATING SOIL TEMPERATURES, AND HOLDING FERTILIZER, SEED AND TOPSOIL IN PLACE. DESIGN CRITERIA/SPECIFICATIONS: DESIGN: (1) PREPARE SOIL AS FOR SEEDING; (2) FOR APPUCATION RATES AND SPECIFICATIONS, SEE TABLE 3-1**; (3) NETS AND MATS USED IN CONJUNCTION WITH MULCH SHOULD BE USED ON SLOPES STEEPER THAN 2:1; (4) WOOD FIBER CELLULOSE BLANKET ARE CONSIDERED PROTECTIVE MULCHES AND CAN BE USED ALONE ON ERODIBLE SOILS AND DURING ALL TIMES OF THE YEAR. MATERIALS: (1) HAY OR STRAW: USE STRAW WHERE MULCH EFFECT IS TO BE MAINTAINED FOR MORE THAN 3 MONTHS. HAY AND STRAW ARE SUBJECT TO WIND BLOWING UNLESS KEPT MOIST OR TIED DOWN. THEY ARE THE MOST COMMON AND WIDELY USED MULCHING MATERIAL; GOOD FOR EROSION CONTROL IN CRITICAL AREAS. ANCHOR BY CRIMPING, DISCING, ROLLING OR PUNCHING INTO SOIL, COVERING WITH NETTING, SPRAYING WITH A CHEMICAL OR FIBER BINDER OR BY KEEPING MOIST; (2) WOOD FIBER CELLULOSE (PARTLY -DIGESTED WOOD FIBERS): WHEN USED FOR EROSION CONTROL ON CRITICAL AREAS, THE APPLICATION RATE SHOULD BE DOUBLED. APPLY WITH HYDROMULCHER. NO TIE DOWN IS REQUIRED. PACKAGED IN 100-LB BAGS. NOT RECOMMENDED FOR HIGHLY ERODIBLE SOILS IN HOT WEATHER; (3) GRAVE, CRUSHED STONE OR SLAG: EXCELLENT MULCH FOR SHORT SLOPE AND AROUND WOODY PLANTS AND ORNAMENTALS. USE WHERE SUBJECT TO FOOT TRAFFIC; (4) CORN STALKS: SHREDDED INTO 4" - 6" LENGTHS, DECOMPOSES SLOWLY AND RESISTS WINDBLOW; (5) WOOD CHIPS: CANNOT BE CLOSELY MOWED. DECOMPOSE SLOWLY AND DO NOT REQUIRE TACKING. DOES NOT PROVIDE NITROGEN TO SEEDS UNLESS TREATED. TENDS TO WASH DOWN SLOPES STEEPER THAN 6%; (6) BARK CHIPS/SHREDDED BARK: CANNOT BE CLOSELY MOWED. ADDITIONAL NITROGEN FOR SEEDS NOT REQUIRED. TENDS TO WASH DOWN SLOPES STEEPER THAN 6%. AVOID TILLING BARK OR SAWDUST INTO SOIL AS IT TENDS TO REMOVE NITROGEN FROM SOIL, RELEASING IT ONLY WHEN IT DECAYS. PROCEDURES: (1) MULCHES SHOULD BE USED FOLLOWING TEMPORARY OR PERMANENT SEEDING; (2) MULCHING SHOULD IMMEDIATELY FOLLOW SEEDING IN AREAS WITH SLOPES STEEPER THAN 2:1; (3) MULCHES SHOULD BE USED IN CLEARED AREAS THAT CANNOT BE SEEDED BECAUSE OF THE SEASON; (4) MULCHES SHOULD BE USED ON EXPOSED SOILS (INCLUDING STOCKPILES WHICH ARE NOT FINAL GRADED WITHIN 15 DAYS) UNLESS COVERED WITH PLASTIC SHEETING. MAINTENANCE: MULCHED AREAS SHOULD BE CHECKED PERIODICALLY, ESPECIALLY FOLLOWING SEVERE STORMS, WHEN DAMAGED AREAS OF MULCH OR TIE -DOWN MATERIAL SHOULD BE REPAIRED. **-SEE TABLE 3-1, THIS SHEET Legend EXISTING LOGGIN SILT FENCE, SEE DETAIL STRAW BALES, SEE DETAIL 200 FT WETLAND BUFFER 12" HIGH COMPACTED SOIL BERM STABILIZATION NOTES (CONT'D.) CONTROL MEASURE: Call before you dig. 800 424-5555 RCW 19.122 TEMPORARY EROSION CONTROL SEEDING. (SEE ALSO TOPSOILING, SURFACE ROUGHENING, MULCHING, PLASTIC SHEETING AND NETS AND MATS). PURPOSE: REDUCES EROSION AND SEDIMENTATION BY TEMPORARILY STABILIZING EXPOSED SOILS FOR UP TO 1 YEAR. DESIGN CRITERIA/SPECIFICATIONS: (1) SEEDING CAN BE DONE DURING THE PERIOD OF MARCH 1 THROUGH SEPTEMBER 30 (IF PLANTED BETWEEN MAY 15 AND AUGUST 15 IRRIGATION MAY BE REQUIRED). SEEDING CAN SOMETIMES ALSO BE DONE SUCCESSFULLY DURING THE REMAINDER OF THE YEAR, OCTOBER 1 THROUGH FEBRUARY 29, PROVIDED THAT THE SEED BED IS IMMEDIATELY STABILIZED BY MULCHING, NET/MATS OR PLASTIC SHEETING; (2) SITE PREPARATION, INCLUDING THE INSTALLATION OF SURFACE RUNOFF CONTROL MEASURES, SHOULD BE COMPLETED PRIOR TO SEEDING. THE SEED BED SHOULD BE FIRM BUT NOT COMPACT, WITH A FAIRLY FINE SURFACE. SURFACE ROUGHENING SHOULD BE DONE AT RIGHT ANGLES TO THE SLOPE AND PREFERABLY TRACK WALKED UP SLOPE. TRACK WALKING IS DRIVING A CRAWLER TRACTOR UP AND DOWN THE SLOPE, LEAVING A PATTERN OF CLEAT IMPRINTS PARALLEL TO THE SLOPE CONTOURS; (3) HYDROSEEDING APPLICATIONS WITH APPROVED SEED -MULCH -FERTILIZER MIXTURES MAY ALSO BE USED; (4) SOIL AMENDMENTS/FERTILIZERS SHOULD BE APPLIED AS RECOMMENDED BY SUPPLIERS. WHEN SEEDING OVER SUBSOIL (WITHOUT TOPSOIL), AVOID OVER -FERTILIZING, ESPECIALLY NEAR AQUATIC FEATURES. INSTEAD, USE MULCH TO ASSIST IN NOURISHING SOIL. PROJECT SITES ADJACENT TO BODIES OF WATER MUST USE NON -PHOSPHORUS FERTILIZER; (5) APPLY AN APPROPRIATE SEED MIXTURE TO THE PREPARED SEED BED AT A RATE OF 120 LBS. PER ACRE. TABLE 3-2** GIVES RECOMMENDED TEMPORARY EROSION CONTROL SEED MIXTURE. MAINTENANCE: (1) INSPECT SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS AND RESEED IMMEDIATELY; (2) SEED SHOULD BE SUPPLIED WITH ADEQUATE MOISTURE. SUPPLY WATER AS NEEDED, ESPECIALLY IN ABNORMALLY HOT OR DRY WEATHER, OR ON ADVERSE SITES. WATER APPLICATION RATES SHOULD BE CONTROLLED TO PREVENT RUNOFF. INSUFFICIENT AMOUNTS OF WATER MAY BE MORE HARMFUL THAN NO WATER. **-SEE TABLE 3-2, THIS SHEET .-1000 SF IMPOUNDMENT AREA REO'D EMERGENCY CONTACT PERSON JEFF BERRY PHONE: (360) 620-4052 -80 3200 SF IMPOUNDMENT EA REQ'D (APPROX 14,000 SF PROVIDED APPROX. 230 LF BERM 12" HIGH FOR FLOW CONT LF BE OR FLOW M ONTROL A REQ'D ED) 40 80 160 \J'( F IMPOUNDMENT AREA REQ'D (APPRRX 37,000 SF PROVIDED) APP X. 260 LF BERM 12" HIGH FOR OW CONTROL 0 320 TABLE 3-1 MULCH MATERIAL, APPLICATION RATES AND SPECIFICATIONS MULCH MATERIAL QUAULTY STANDARDS APPLICATION RATES PER 1000 SQ FT APPLICATION RATES PER ACRE DEPTH OF APPLICATION GRAVEL, CRUSHED STONE OR SLAG WASHED: 3/4" - 1-1/2" SIZE 9 CU YDS 400 CU YDS. 3" HAY OR STRAW AIR-DRIED, FREE FROM UNDESIRABLE SEED & COARSE MATERIAL 75-100 LBS., 2-3 BALES 1.5 - 2.5 TONS (90-100 BALES) LIGHTLY COVER ENTIRE SURFACE (MIN. 2") WOOD FIBER CELLULOSE DYED GREEN.
