IMMEDIATELY AFTER FACILITY EXCAVATION/CONSTRUCTION, THE GEOTECHNICAL ENGINEER IS TO PERFORM A SUFFICIENT NUMBER OF INFILTRACTION TESTS (2 MINIMUM) TO VERIFY IF THE INFILTRATION RATES AND DEPTHS TO GROUND WATER AND/OR IMPERVIOUS SOIL LAYER USED FOR DESIGN ARE STILL ACCEPTABLE.

ON DISTURBED AREAS THAT REQUIRE COVER MEASURES FOR LESS THAN 30 DAYS. 2. AS A COVER FOR SEED DURING THE WET SEASON AND DURING THE HOT SUMMER MONTHS. 3. DURING THE WET SEASON ON SLOPES STEEPER THAN 3HA V WITH MORE THAN 10 FEET OF VERTICAL RELIEF. MAINTENANCE STANDARDS: 1. THE THICKNESS OF THE MULCH COVER MUST BE MAINTAINED. 2. ANY AREAS THAT EXPERIENCE EROSION SHALL BE RE -MULCHED AND/OR PROTECTED WITH A NET OR BLANKET. IF THE EROSION PROBLEM IS DRAINAGE RELATED, THEN THE DRAINAGE PROBLEM SHALL BE ASSESSED AND ALTERNATE DRAINAGE SUCH AS INTERCEPTOR SWALES MAY BE NEEDED TO FIX THE PROBLEM AND THE ERODED AREA RE -MULCHED. MULCH STANDARDS AND GUIDELINES: • STRAW: 2" TO 3" THICK, 2-3 BALES PER 1,000 SF OR 2-3 TONS PER ACRE • WOOD FIBER CELLULOSE: APPROXIMATELY 25-30 LBS PER 1,000 SF OR 1,000 TO 1,500 LBS PER ACRE • COMPOST: 2" THICK MIN., APPROXIMATELY 100 TONS PER ACRE (APPROXIMATELY 800 LBS PER CUBIC YARD) • HYDRAULIC MATRICES (BONDED FIBER MATRIX): APPLY AT RATES FROM 3,000 LBS PER ACRE TO 4,000 LBS PER ACRE AND BASED ON MANUFACTURERS'RECOMMENDAiIONS. • CHIPPED SITE VEGETATION: 2'THICK MIN. EROSION/8801 AENT CONTROL. NOTES: 1. APPROVAL OF THIS EROSION/SEDIMENTATION CONTROL (ESC) PLAN DOES NOT CONSTITUTE AN APPROVAL OF PERMANENT ROAD OR DRAINAGE DESIGN (I.E. SIZE AND LOCATION OF ROADS, PIPES, RESTRICTORS, CHANNELS, RETENTION FACILITIES, UTILITIES, ETC.). 2. THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION, MAINTENANCE REPLACEMENT, AND UPGRADING OF THESE ESC FACILITIES IS THE RESPONSIBILITY OF TIME APPLICANT/CONTRACTOR UNTIL ALL CONSTRUCTION IS APPROVED. 3. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN SHALL BE CLEARLY FLAGGED IN THE FIELD PRIOR TO CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO DISTURBANCE BEYOND THE FLAGGED CLEARING LIMITS SHALL BE PERMITTED. THE FLAGGING SHALL BE MAINTAINED BY THE APPLICANT/CONTRACTOR FOR THE DURATION OF CONSTRUCTION. 4. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED IN CONJUNCTION WITH ALL CLEARING AND GRADING ACTIVITIES, AND IN SUCH A MANNER AS TO INSURE THAT SEDIMENT LADEN WATER DOES NOT ENTER THE DRAINAGE SYSTEM OR VIOLATE APPLICABLE WATER STANDARDS. 5. THE ESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED (I.E. ADDITIONAL SUMPS, RELOCATION OF DITCHES AND SILT FENCES, ETC.) AS NEEDED FOR UNEXPECTED STORM EVENTS. 6. THE ESC FACILITIES SHALL BE INSPECTED DAILY BY THE APPLICANT/CONTRACTOR AND MAINTAINED AS NECESSARY TO ENSURE THEIR CONTINUED FUNCTIONING. 7. ANY AREA STRIPPED OF VEGETATION, INCLUDING ROADWAY EMBANKMENTS, WHERE NO FURTHER WORK IS ANTICIPATED OR A PERIOD OF 2 DAYS (WET SEASON) OR 7 DAYS (DRY SEASON), SHALL BE IMMEDIATELY STABILIZED WITH THE APPROVED ESC METHODS (I.E. SEEDING, MULCHING, NETTING, EROSION BLANKETS, ETC.) 8. ANY AREA NEEDING ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN 15 DAYS. 9. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN THE 24 HOURS FOLLOWING A STORM EVENT. 10. AT NO TIME SHALL MORE THAN ONE FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN, ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT -LADEN WATER INTO THE DOWNSTREAM SYSTEM. 11. STABILIZED CONSTRUCTION ENTRANCES AND WASH PADS SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT. ADDITIONAL MEASURES MAY BE REQUIRED TO INSURE THAT ALL PAVED AREAS ARE KEPT CLEAN FOR THE DURATION OF THE PROJECT. 12, WET SEASON REQUIREMENTS AS DESCRIBED IN APPENDIX D, SECTION 0.2.4.2 OF THE KCSWDM ARE IN EFFECT BEGINNING OCTOBER 1 THROUGH APRIL 30. 13. ANY PERMANENT RETENTION/DETENTION FACILITY USED AS A TEMPORARY SETTLING BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN INFILTRATION OR DISPERSION SYSTEM, THE FACILITY SHALL NOT BE USED AS A TEMPORARY SETTLING BASIN. NO UNDERGROUND DETENTION TANKS OR VAULTS SHALL BE USED AS A TEMPORARY SETTLING BASIN. 14, WHERE SEEDING FOR TEMPORARY EROSION CONTROL IS REQUIRED, FAST GERMINATING GRASSES SHALL BE APPLIED AT AN APPROPRIATE RATE (I.E. ANNUAL OR PERENNIAL RYE APPLIED AT APPROXIMATELY 80 POUNDS PER ACRE), 15. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT A MINIMUM THICKNESS OF TWO INCHES. 16. MANAGEMENT PRACTICES PROVIDING SIGNIFICANT TREE PROTECTION SHALL BE PROVIDED PER SECTION 19.120 OF FWRC. IA - SEEDING NOTES 1. THE BEST TIME TO SEED IS APRIL i THROUGH JUNE 30, AND SEPTEMBER 1 THROUGH OCTOBER 15. AREAS MAY BE SEEDED BETWEEN JULY 1 AND AUGUST 31, BUT IRRIGATION MAY BE REQUIRED IN ORDER TO GROW ADEQUATE COVER. AREAS MAY ALSO BE SEEDED DURING THE WINTER MONTHS, BUT IT MAY TAKE SEVERAL MONTHS TO DEVELOP A DENSE GROUNDCOVER DUE TO COLD TEMPERATURES. THE APPLICATION AND MAINTENANCE OF MULCH IS CRITICAL FOR WINTER SEEDING. 2. TO PREVENT SEED FROM BEING WASHED AWAY, CONFIRM THAT ALL REQUIRED SURFACE WATER CONTROL MEASURES HAVE BEEN INSTALLED. 3. THE SEEDBED SHOULD BE FIRM BUT NOT COMPACTED BECAUSE SOILS THAT ARE WELL COMPACTED WILL NOT VEGETATE AS QUICKLY OR THOROUGHLY. 4. IN GENERAL, 10-20-20 N-P-K (NITROGEN -PHOSPHORUS -POTASSIUM) FERTILIZER MAY BE USED AT A RATE OF 90 POUNDS PER ACRE. SLOW -RELEASE FERTILIZERS ARE PREFERRED BECAUSE THEY ARE MORE EFFICIENT AND HAVE FEWER ENVIRONMENTAL IMPACTS. IT IS RECOMMENDED THAT AREAS BEING SEEDED FOR FINAL LANDSCAPING CONDUCT SOIL TESTS TO DETERMINE THE EXACT TYPE AND QUANTITY OF FERTILIZER NEEDED. THIS WILL PREVENT THE OVERAPPLICATION OF FERTILIZER. DISTURBED AREAS WITHIN 200 FEET OF WATER BODIES AND WETLANDS MUST USE SLOWRELEASE LOW -PHOSPHORUS FERTILIZER (TYPICAL PROPORTIONS 3-1-2 N-P-K). 5. THE FOLLOWING REQUIREMENTS APPLY TO MULCHING: a. MULCH IS ALWAYS REQUIRED FOR SEEDING SLOPES GREATER THAN 3H:1V (SEE SECTION D.4.2.1 OF THE 2016 KING COUNTY SURFACE WATER DESIGN MANUAL). b. IF SEEDING DURING THE WET SEASON, MULCH IS REQUIRED. c. THE USE OF MULCH MAY BE REQUIRED DURING THE DRY SEASON AT THE COUNTY'S DISCRETION IF GRASS GROWTH IS EXPECTED TO BE SLOW, THE SOILS ARE HIGHLY ERODIBLE DUE TO SOIL TYPE OR GRADIENT, THERE IS A WATER BODY CLOSE TO THE DISTURBED AREA, OR SIGNIFICANT PRECIPITATION IS ANTICIPATED BEFORE THE GRASS WILL PROVIDE EFFECTIVE COVER. d. MULCH MAY BE APPLIED ON TOP OF THE SEED OR SIMULTANEOUSLY BY HYDROSEEDING. 6. HYDROSEEDING IS ALLOWED AS LONG AS TACKIFIER IS INCLUDED. HYDROSEEDING WITH WOOD FIBER MULCH IS ADEQUATE DURING THE DRY SEASON. DURING THE WET SEASON, THE APPLICATION RATE SHALL BE DOUBLED BECAUSE THE MULCH AND TACKIFIER USED IN HYDROSEEDING BREAK DOWN FAIRLY RAPIDLY IT MAY BE NECESSARY IN SOME APPLICATIONS TO INCLUDE STRAW WITH THE WOOD FIBER, BUT THIS CAN BE DETRIMENTAL TO GERMINATION. 7. AREAS TO BE PERMANENTLY LANDSCAPED SHALL USE SOIL AMENDMENTS. GOOD QUALITY TOPSOIL SHALL BE TILLED INTO THE TOP SIX INCHES TO REDUCE THE NEED FOR FERTILIZER AND IMPROVE THE OVERALL SOIL QUALITY. MOST NATIVE SOILS WILL REQUIRE THE ADDITION OF FOUR INCHES OF WELL -ROTTED COMPOST TO BE TILLED INTO THE SOIL TO PROVIDE A GOOD QUALITY TOPSOIL. COMPOST USED SHOULD MEET SPECIFICATIONS IN REFERENCE 11-C OF THE 2016 KING COUNTY SURFACE WATER DESIGN MANUAL. 8. THE SEED MIXES LISTED BELOW INCLUDE RECOMMENDED MIXES FOR BOTH TEMPORARY AND PERMANENT SEEDING. THESE MIXES, WITH THE EXCEPTION OF THE WETLAND MIX, SHALL BE APPLIED AT A RATE OF 120 POUNDS PER ACRE. THIS RATE MAY BE REDUCED IF SOIL AMENDMENTS OR SLOW -RELEASE FERTILIZERS ARE USED. LOCAL SUPPLIERS SHOULD BE CONSULTED FOR THEIR RECOMMENDATIONS BECAUSE THE APPROPRIATE MIX DEPENDS ON A VARIETY OF FACTORS, INCLUDING EXPOSURE, SOIL TYPE, SLOPE, AND EXPECTED FOOT TRAFFIC. ALTERNATIVE SEED MIXES APPROVED BY THE COUNTY MAY BE USED. % WEIGHT % PURITY % GERMINATION CHEWINGS OR RED FESCUE (FESTUCA RUBRA 40 98 90 VAR.

IF WINTER WEATHER PREVENTS ADEQUATE GRASS GROWTH, THIS TIME LIMIT MAY BE RELAXED AT THE DISCRETION OF THE COUNTY WHEN CRITICAL AREAS WOULD OTHERWISE BE PROTECTED. 2. AFTER ADEQUATE COVER IS ACHIEVED, ANY AREAS THAT EXPERIENCE EROSION SHALL BE RE -SEEDED AND PROTECTED BY MULCH. IF THE EROSION PROBLEM IS DRAINAGE RELATED, THE PROBLEM SHALL BE FIXED AND THE ERODED AREA RE -SEEDED AND PROTECTED BY MULCH. 3. SEEDED AREAS SHALL BE SUPPLIED WITH ADEQUATE MOISTURE, BUT NOT WATERED TO THE EXTENT THAT IT CAUSES RUNOFF Know what's below. Call before you dig.
