C❑NTR❑LLING OFF -SITE EROSION, PR❑PERTIES AND WATERWAYS DOWNSTREAM FROM DEVELOPMENT SITES SHALL BE PROTECTED FROM EROSION DUE TO INCREASES IN THE VOLUME, VEL❑CITY, AND PEAK FLOW RATE OF STORMWATER RUNOFF FROM THE DEVELOPMENT SITE BY THE IMPLEMENTATION OF APPR❑PRIATE BMPS TO MINIMIZE ADVERSE DOWNSTREAM IMPACTS. 11. STABILIZATION OF TEMPORARY CONVEYANCE CHANNELS AND OUTLETS, ALL TEMPORARY ❑N-SITE CONVEYANCE CHANNELS SHALL BE DESIGNED, CONSTRUCTED AND STABILIZED TO PREVENT EROSION FROM THE EXPECTED FLOW VEL❑CITY FROM A 2-YEAR FREQUENCY, 24-HOUR DURATION STORM FOR THE POST -DEVELOPMENT CONDITION. STABILIZATION ADEQUATE TO PREVENT EROSION OF OUTLETS, ADJACENT STREAMBANKS, SLOPES AND DOWNSTREAM REACHES SHALL BE PROVIDED AT THE OUTLETS OF ALL CONVEYANCE SYSTEMS, 12. STORM DRAIN INLET PR❑TECTI❑N. ALL STORM DRAIN INLETS MADE OPERABLE DURING C❑NSTRUCTI❑N SHALL BE PROTECTED SO THAT STORMWATER RUNOFF SHALL NOT ENTER THE CONVEYANCE SYSTEM WITH❑UT FIRST BEING FILTERED OR OTHERWISE TREATED TO REMOVE SEDIMENT. AFTER PROPER WRITTEN APPLICATION, THE REQUIREMENT FOR INLET PR❑TECTI❑N MAY BE WAIVED BY THE DIRECTOR ON A SITE -SPECIFIC BASIS WHEN THE CONVEYANCE SYSTEM DOWNSTREAM OF THE INLET DISCHARGES TO AN APPR❑PRIATE SEDIMENT CONTAINMENT BMP AND THE CONVEYANCE SYSTEM CAN BE ADEQUATELY CLEANED FOLL❑WING SITE STABILIZATION. 13. UNDERGROUND UTILITY C❑NSTRUCTI❑N. THE CONSTRUCTION OF UNDERGROUND UTILITY LINES SHALL BE LIMITED, WHERE FEASIBLE, TO NO MORE THAN 500 FEET OF OPEN TRENCH AT ANY ONE TIME. WHERE CONSISTENT WITH SAFETY AND SPACE CONSIDERATIONS, EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF THE TRENCH, DEWATERING DEVICES SHALL DISCHARGE TO AN APPROPRIATE SEDIMENT TRAP OR POND, PRECEDED BY ADEQUATE ENERGY DISSIPATION, PRIOR TO RUNOFF LEAVING THE SITE. 14. CONSTRUCTED ACCESS R❑UTES, WHEREVER CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED ROADS, PROVISIONS MUST BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT (MUD) ONTO THE PAVED ROAD BY USE OF APPR❑PRIATE BMP'S SUCH AS A STABILIZED CONSTRUCTION ENTRANCE. IF SEDIMENT IS TRANSPORTED ONTO A ROAD SURFACE, THE ROADS SHALL BE CLEANED THOROUGHLY, AS A MINIMUM, AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM ROADS BY SHOVELING OR SWEEPING AND BE TRANSPORTED TO A CONTROLLED SEDIMENT DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. 15. REMOVAL OF TEMPORARY BMPS. ALL TEMPORARY EROSION AND SEDIMENT CONTROL BMPS SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION IS ACHIEVED OR AFTER THE TEMPORARY BMPS ARE NO LONGER NEEDED. TRAPPED SEDIMENT SHALL BE REMOVED OR STABILIZED ON -SITE, DISTURBED SOIL AREAS RESULTING FROM REMOVAL OF TEMPORARY BMPS SHALL BE PERMANENTLY STABILIZED. THE REMOVAL OF TEMPORARY EROSION AND SEDIMENT CONTROL BMPS MAY NOT BE REQUIRED FOR THOSE PROJECTS, SUCH AS SINGLE FAMILY PLATS, THAT WILL BE FOLLOWED BY ADDITIONAL CONSTRUCTION UNDER A DIFFERENT PERMIT. IN THESE CIRCUMSTANCES, THE NEED FOR REM❑VING OR RETAINING THE MEASURES WILL BE EVALUATED ON A SITE -SPECIFIC BASIS. 16. DEWATERING C❑NSTRUCTI❑N SITES. DEWATERING DEVICES SHALL DISCHARGE INTO AN APPROPRIATE SEDIMENT TRAP OR POND, DESIGNED TO ACCEPT SUCH A DISCHARGE PRECEDED BY ADEQUATE ENERGY DISSIPATION, PRIOR TO RUNOFF LEAVING THE SITE. 17. CONTROL OF POLLUTANTS OTHER THAN SEDIMENT ON CONSTRUCTION SITES, ALL POLLUTANTS OTHER THAN SEDIMENT THAT OCCUR ❑N-SITE DURING CONSTRUCTION SHALL BE HANDLED AND LEGALLY DISP❑SED OF IN A MANNER THAT DOES NOT CAUSE CONTAMINATION OF STORM OR SURFACE WATERS. POLLUTANTS OF CONCERN INCLUDE, BUT ARE NOT LIMITED TO, FUELS, LUBRICANTS, SOLVENTS, CONCRETE BI-PR❑DUCTS AND CONSTRUCTION MATERIALS 18. MAINTENANCE. ALL TEMPORARY AND PERMANENT EROSION AND SEDIMENT CONTROL BMPS SHALL BE MAINTAINED AND REPAIRED AS NEEDED TO ASSURE C❑NTINUED PERFORMANCE OF THEIR INTENDED FUNCTION. ALL MAINTENANCE AND REPAIR SHALL BE CONDUCTED IN ACCORDANCE WITH THE MANUAL. THE APPLICANT SHALL BE RESPONSIBLE FOR ASSURING THAT ANY SUCH FACILITIES DAMAGED DURING FLOODS, STORMS OR OTHER ADVERSE WEATHER CONDITIONS ARE IMMEDIATELY RETURNED TO NORMAL OPERATING C❑NDITI❑N. 19. FINANCIAL LIABILITY. A PERFORMANCE COVENANT OR PERFORMANCE SURETY, SHALL BE REQUIRED FOR ALL PROJECTS TO ENSURE COMPLIANCE WITH THE APPROVED EROSION AND SEDIMENT CONTROL PLAN, AS OUTLINED IN SECTION 4.0 OF THE KITSAP COUNTY STORMWATER ORDINANCE, 1. ON SHALLOW SLOPE, NETTING MAY BE APPLIED ACROSS THE SLOPE. (SLOPES UP TO L1). 2. ON STEEP SLOPES, APPLY STRIPS OF NETTING PARALLEL TO THE DIRECTION OF FLOW AND ANCHOR SECURELY, (SLOPES GREATER THAN 1:1) 3, WHERE THERE IS A BERM AT THE TOP OF THE SLOPE, BRING THE NETTING OVER THE BERM AND ANCHOR IT BEHIND THE BERM, 4, BRING THE NETTING DOWN TO A LEVEL AREA BEFORE TERMINATING THE INSTALLATION, TURN THE END UNDER 6' AND STAPLE AT 12' INTERVALS. 5, IN DITCHES, APPLY NETTING PARALLEL TO THE DIRECTION OF FLOW. USE CHECK SLOTS EVERY 15 FEET. DO NOT J❑IN STRIPS IN THE CENTER OF THE DITCH. 6, NETS AND MATS USED ALONE, WITHOUT MULCH, DO NOT RETAIN S❑IL TEMPPERATURE, 7, IT IS CRITICAL DURING INSTALLATION TO ❑BTAIN FIRM, CONTINUOUS CONTACT BETWEEN THE NET/MAT MATERIAL AND THE SOIL. WITHOUT SUCH CONTACT, THE MATERIAL IS USELESS AND EROSION OCCURS. 8, WHEN ANCHORING MATERIAL, IT IS IMPORTANT TO USE AN ADEQUATE NUMBER OF STAPLES AND TO ROLL THE MATERIAL AFTER LAYING IT TO ENSURE THAT THE S❑IL IS PR❑TECTED, NETTING SHOULD BE SECURELY ANCHORED TO THE S❑IL WITH NO. 11 GAUGE WIRE STAPLES AT LEAST 6-INCHES LONG, WITH AN OVERLAP OF 3-INCHES. 9, SITE PREPARATION IS THE SAME AS FOR TEMPORARY SEEDING, 10.

SURFACE ROUGHENING 1, SURFACE ROUGHENING IS INTENDED TO AID IN THE ESTABLISHMENT OF VEGETATIVE COVER, WHICH IN TURN IS INTENDED TO PROTECT THE FACE OF THE SLOPE FROM RAINFALL IMPACT AND SEEDFLOW, BIND THE SURFACE OF THE SLOPE TO RETARD EROSION, AND REDUCE THE VELOCITY OF SURFACE RUNOFF, SURFACE ROUGHENING IS NOT INTENDED TO ACCOMPLISH ANY OF THE ABOVE BY ITSELF, AND DEFINITELY SHOULD NOT BE USED TO DIRECTLY REDUCE THE VEL❑CITY OF SURFACE RUNOFF, 2, GRADED SLOPES STEEPER THAN 3:1 BUT LESS THAN 2:1 SHOULD BE ROUGHENED BEFORE SEEDING. THIS CAN BE ACC❑MPLISHED IN A VARIETY OF WAYS, INCLUDING 'TRACK -WALKING', OR DRIVING A CRAWLER TRACTOR UP AND DOWN THE SLOPE, LEAVING A PATTERN OF CLEAT IMPRINTS PARALLELTO SLOPE CONTOURS, THE TREAD IMPRINTS ARE IDEAL PLACES TO TRAP SEEDS AND ENCOURAGE PLANTS TO BECOME ESTABLISHED. 3, GRADED AREAS STEEPER THAN 211 SHOULD BE STAIR -STEPPED WITH BENCHES, THE STAIR -STEPPING WILL HELP VEGETATION BECOME ESTABLISHED AND ALSO TRAP SOIL ERODED FROM THE SLOPES ABOVE, FILTER FABRIC FENCE INLET BARRIER 1. THIS DEVICE IS APPLICABLE WHERE THE INLET DRAINS A RELATIVELY SMALL(LESS THAN 1 ACRE) FLAT AREA (LESS THAN 5% SLOPE) 2. PLACE 2' X 2' WOODEN STAKES AROUND THE PERIMETER OF THE INLET A MAXIMUM OF 3-FEET APART AND DRIVE THEM AT LEAST 18 INCHES INTO THE GROUND. THE STAKES MUST BE AT LEAST 3-LONG. 3, EXCAVATE A TRENCH APPDXIMATELY 8-INCHES WIDE AND 12- INCHES DEEP AROUND THE OUTSIDE PERIMETER OF THE STAKES, 4, STAPLE THE FABRIC FILTER TO THE WOODEN STAKES S❑ THAT 32-INCHES OF THE FABRIC EXTENDS AND CAN BE FORMED INTO THE TRENCH. USE HEAVY-DUTY WIRE STAPLES AT LEAST 3 -INCH LONG. 5. BACKFILL THE TRENCH WITH 3/4 -INCH MINUS WASHED GRAVEL ALL THE WAY AROUND. 6. DO NOT PLACE FABRIC UNDER THE GATE, AS THE COLLECTED SEDIMENT MAY FALL INTO THE DRAIN WHEN THE FABRIC IS RETIEVED. TRENCHING 1. FOR TRENCHES ON A D❑WNSLOPE OF MORE THAN 5%, NO MORE THAN 500-FEET OF TRENCH SHOULD BE OPENED AT ONE TIME, 2, PLACE EXCAVATED MATERIAL FROM TRECHES ON THE UPHILL SIDE OF THE TRENCH WHEN SAFETY AND SPACE C❑NSRAINTS ALLOW. A NOTE TO THIS EFFECT SHOULD BE INCLUDED ON THE ESC PLAN, 3. DIRECT THE DISCHARGE OF DEWATERING DEVICES FROM TRENCHES OR OTHER AREAS S❑ AS NOT TO ADVERSELY IMPACT FL❑WING STREAMS, DRAINAGE SYSTEMS OR OFF -SITE PROPERTY, DEWATERING DEVICES SHALL NOT DISCHARGE TO SANITARY SEWERS. MULCHING 1. MATERIALS USED FOR MULCHING ARE RECOMMENDED TO BE WOOD FIBER CELLULOSE, AND SHOULD BE APPLIED AT A RATE OF 1000 POUNDS PER ACRE, 2, MULCH SHOULD BE APPLIED IN ALL AREAS WITH EXPOSED SLOPES GREATER THAN 2:1 (HORIZ❑NTAL:VERTICAL). 3. MULCHING SHOULD BE USED IMMEDIATELY AFTER SEEDING OR IN AREAS WHICH CANNOT BE SEEDED BECAUSE OF THE SEASON. ALL AREAS REQUIRING MULCH SHALL BE COVERED BY NOVEMBER 1, ST❑CKPILE MANAGEMENT 1. ST❑CKPILE 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, TOPS❑IL SHALL NOT BE PLACED WHILE IN A FROZEN OR MUDDY C❑NDITI❑N, WHEN THE SUBGRADE IS EXCESSIVELY WET, OR WHEN CONDITIONS EXIST THAT MAY OTHERWISE BE DETRIMENTAL TO PROPER GRADING OR PROPOSED SODDING OR SEEDING. 4.
