THIS CAN BE DONE BEFORE OR AFTER PERMANENT SEEDING. IHE TYPES OF <br />MULCHES AVAILABLE ARE DESCRIBED BELOW (TAKEN FROM THE D.O.E. MANUAL): <br />STRAW - MOST COMMONLY USED IN CONJUNCTION WITH SEEDING. ITS USE IS RECOMMENDED WHERE IMMEDIATE PROTECTION IS REQUIRED AND <br />PREFERABLY WHERE THE NEED FOR PROTECTION WILL BE LESS THAN 3 MONTHS. THE STRAW SHOULD COME FROM WHEAT OR OATS, AND MAY <br />BE SPREAD BY HAND OR MACHINE. STRAW CAN BE WINDBLOWN AND MUST BE ANCHORED DOWN (ROLLING OR PUNCHING INTO SOIL, COVERING <br />WITH NETTING, SPRAYING TACKIFIER). CORN STALKS - THESE SHOULD BE SHREDDED INTO 4 TO 6-INCH LENGTHS STALKS DECOMPOSE <br />SLOWLY AND ARE RESISTANT TO WINDBLOW. <br />WOOD CHIPS/BARK CHIPS - SUITABLE FOR AREAS THAT WILL NOT BE CLOSELY MOWED, AND AROUND ORNAMENTAL PLANTINGS CHIPS <br />DECOMPOSE SLOWLY AND DO NOT REQUIRE TACKING. WOOD CHIPS MUST BE TREATED WITH 12 POUNDS NITROGEN PER TON TO PREVENT <br />NUTRIENT DEFICIENCY IN PLANTS (NOT NECESSARY FOR BARK). WOOD AND BARK CHIPS TEND TO WASH DOWN SLOPES OF MORE THAN 6 <br />PERCENT AND CREATE PROBLEMS BY CLOGGING INLET GRATES ETC. AND ARE THEREFORE NOT RECOMMENDED FOR USE IN THOSE AREAS. <br />WOOD FIBER - USED IN HYDRO -SEEDING OPERATIONS, APPLIED AS PART OF THE SLURRY. THIS FORM OF MULCH DOES NOT PROVIDE <br />SUFFICIENT PROTECTION TO ERODIBLE SOILS TO BE USED ALONE DURING THE HEAT OF SUMMER OR FOR LATE FALL SEEDINGS. WOOD FIBER <br />HYDRO -SEED SLURRIES MAY BE USED TO TACK STRAW MULCH. THIS COMBINATION TREATMENT IS WELL SUITED FOR STEEP SLOPES AND <br />CRITICAL AREAS NETS AND MATS - USED ALONE NETTING DOES NOT RETAIN SOIL MOISTURE OR MODIFY SOIL TEMPERATURE IT STABILIZES <br />THE SOIL SURFACE WHILE GRASSES ARE BEING ESTABLISHED, AND IS USEFUL IN GRASSED WATERWAYS AND ON SLOPES LIGHT NETTING MAY <br />ALSO BE USED TO HOLD OTHER MULCHES IN PLACE ITS RELATIVELY HIGH COST MAKES IT MOST SUITABLE FOR SMALL SITES. <br />GENERAL <br />1. ALL GRADING SHALL COMPLY TO CHAPTER 1E OF THE INTERNATIONAL BUILDING CODE AND SNOHOMISH COUNTY CODE CHAPTER 30.63B <br />GRADING <br />2. TESC. MEASURES SHALL BE INSTALLED PRIOR TO ANY SITE WORK (SEE ATTACHED DETAILED TESC. PLAN). <br />J. PUBLIC STREETS ARE TO BE KEPT CLEAR OF DIRT AND DEBRIS DURING EXCAVATION AND FILL OPERATIONS <br />4. NONCOMPLIANCE WITH THE EROSION CONTROL REQUIREMENTS WATER QUALITY REQUIREMENTS AND/OR CLEARING LIMITS MAY RESULT IN <br />REVOCATION OF PROJECT PERMITS, PLAN APPROVAL AND BOND FORECLOSURES <br />5. CONSTRUCTION ACCEPTANCE WILL BE SUBJECT TO A WELL ESTABLISHED GROUND COVER THAT FULFILLS THE REQUIREMENT OF THE <br />APPROVED CONSTRUCTION PLANS AND TITLE 30, SNOHOMISH COUNTY DRAINAGE ORDINANCE <br />6. ALL AREAS TO BE SEEDED SHALL BE CULTIVATED TO THE SATISFACTION OF THE COUNTY INSPECTOR. THIS MAY BE ACCOMPLISHED BY <br />DISCING, RAKING, HARROWING OR OTHER ACCEPTABLE MEANS. PERFORM ALL CULTURAL OPERATIONS ACROSS OR AT RIGHT ANGLES TO THE <br />SLOPE IF NECESSARY, SURFACE RUNOFF CONTROL MEASURES SUCH AS GRADIENT TERRACES INTERCEPTOR DIKE/SWALES LEVEL <br />SPREADERS AND SEDIMENT BASINS SHALL BE INSTALLED PRIOR TO SEEDING. <br />Z ALL DISTURBED AREAS SUCH AS DETENTION FACILITIES ROADWAY BACK -SLOPES ETC. SHALL BE SEEDED WIN A PERENNIAL GROUND <br />COVER GRASS TO MINIMIZE EROSION. GRASS SEEDING WILL BE DONE USING AN APPROVED HYDROSEEDER OR AS OTHERWISE APPROVED BY <br />SNOHOMISH COUNTY. <br />6. IMMEDIATELY FOLLOWING FINISH GRADING PERMANENT VEGETATION (CONSISTING OF RAPID, PERSISTENT AND LEGUME) WILL BE APPLIED. <br />(MINIMUM 601 PER ACRE). THIS IS TO INCLUDE THE FOLLOWING: 207.ANNUAL, PERENNIAL OR HYBRID RYE GRASS 40%Y.Y. CREEPING RED <br />FESCUE, 409.E WHITE CLOVER, HYDROSEED REQUIRED. <br />9. FERTLIZER SHALL BE APPLIED AT 400,E PER ACRE OF 10-20-20 (10 POUNDS PER 1100 SQUARE FEET) OR EQUIVALENT DEVELOPMENTS <br />ADJACENT TO WATER BODIES SHALL USE NON -PHOSPHOROUS FERTILIZER. <br />10. ALL CUT AND FILL SLOPES SHALL BE A MAXIMUM OF 2: 1. <br />11. STOCKPILES ARE TO BE LOCATED IN SAFE AREAS AND ADEQUATELY PROTECTED WITHIN 24 HOURS TO PREVENT EROSION. HYDROSEED <br />PREFERRED. <br />12. DURING PERIODS OF WET WEATHER, THE GRADING CONTRACTOR SHALL TAKE ALL PRECAUTIONS TO LIMIT SURFACE DISTURBANCE AND <br />PROTECT THE SITE GRADING AREA FROM EXCESSIVE RUNOFF EROSION. <br />13, AREAS TO RECEIVE FILL SHALL BE CLEARED OF ALL VEGETATION AND DELETERIOUS MATTER. <br />14. ALL FILL MATERIALS USED SHALL BE FREE OF VEGETATION AND DELETERIOUS MATTER AND SHALL NOT CONTAIN ROCKS GREATER THAN 6 <br />INCHES IN DIAMETER. <br />15. STRUCTURAL FILLS SHALL BE PLACED IN B" TO 10" THICK LOOSE HORIZONTAL LIFTS AND SPREAD UNIFORMLY. <br />16. ALL STRUCTURAL FILLS SHALL BE COMPACTED TO A MINIMUM OF 95999 OF MAXIMUM DENSITY AS DETERMINED BY MODIFIED PROCTOR <br />TEST (ASTM D-1557-70). <br />1 Z THE SURFACE OF ALL SLOPES SHALL BE COMPACTED. THIS MAY BE ACCOMPLISHED BY OVER -BUILDING THE SLOPES, THEN CUTTING BACK <br />TO FINAL GRADES, OR BY RUNNING THE COMPACTOR OVER THE SLOPE AS EACH FILL LIFT IS BEING PLACED. ALL SLOPES SHALL BE <br />COMPACTED BY 7HE END OF EACH WORKING DAY. <br />1& DISTURBED AREAS TO BE STABILIZED WITH HYDROSEED OR STRAW MULCH WITHIN 24 HOURS OF COMPLETION OF FINAL GRADING DURING WET <br />WEATHER. <br />TT <br />CITY ®V E\JFPF <br />DONNA BRESKE & ASSOCIATES <br />LAND USE PLANNING & CIVIL ENGINEERING <br />6621 FOSTER SLOUGH RD <br />SNOHOMISH) WA98290 <br />PHONE: 206-715-9582 <br />DON NAB@ DON NABRESKE.COM <br />
