OBTAIN PLAN APPROVAL BEFORE BEGINNING WORK. 2. INSTALL APPLICABLE E&S CONTROL MEASURES PRIOR TO ONSET OF ANY LAND DISTURBING (INCLUDING DEMOLITION) ACTIVITIES. 3. INSTALL CONSTRUCTION ENTRANCE AND SILT FENCE ACCORDING TO PLANS AND AS NEEDED. 4. CONSTRUCT TEMPORARY SEDIMENT TRAP WITH BAFFLES, SWALES AND CHECK DAMS. 5. PROVIDE STABILIZATION FOR SWALES AND SKIMMER BASINS IMMEDIATELY UPON COMPLETION OF THEIR INSTALLATION. 6. BEGIN GRADING AND CONSTRUCTION OF ROADS. MAINTAIN DEVICES AS NEEDED. ,. 7. AFTER GRADING IS COMPLETED, TOPSOIL STOCKPILE AND WASTE AREAS TO BE REMOVED AND AREA STABILIZED. 8. WHEN ROAD CONSTRUCTION AND SITE GRADING IS COMPLETE AND ALL DISTURBED AREAS ARE STABILIZED COMPLETELY, INCLUDING WASTE PILES, REMOVE TEMPORARY MEASURES INCLUDING SEDIMENTS INSIDE SKIMMER BASIN AND RESTORE TO DESIGN DIMENSIONS THEN STABILIZE. 9. VEGETATION TO BE ESTABLISHED ON SLOPES GREATER THAN 3:1 WITHIN 7 DAYS, AND 14 DAYS ON OTHER AREAS, FOLLOWING COMPLETION OF ANY PHASE OF GRADING. ANY DISTURBED AREAS INCLUDING SPOIL, TOPSOIL, WASTE PILES TO BE STABILIZED. SEEDING TO BE DONE AT RATES AS INDICATED ON PLAN 10. ALL EROSION & SEDIMENT CONTROL MEASURE MUST BE MAINTAINED UNTIL PERMANENT VEGETATION IS ESTABLISHED. 11. AFTER ALL SEDIMENT -SEDIMENT PRODUCING AREAS HAVE BEEN PERMANENTLY ESTABLISHED, REMOVE THE STRUCTURE AND ALL THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE USING EROSION CONTROL MATTING, NORTH AMERICAN GREEN SINGLE NET EROSION CONTROL BLANKET D575 OR EQUIVALENT. MAINTENANCE: 1. EROSION AND SEDIMENTATION CONTROL DEVICES SHALL BE CHECKED AT LEAST ONCE EVERY WEEK AND AFTER EVERY RUN-OFF PRODUCING RAINFALL. 2. SEDIMENT SHALL BE REMOVED AND DEVICES REPAIRED AND/OR REPLACED AS NECESSARY. �I SEEDBED PREPARATION: CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3" DEEP OVER ADVERSE SOIL CONDITIONS, IF i AVAILABLE. RIP ENTIRE AREA 6" DEEP. REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER -.. OBSTRUCTIONS LEAVING SURFACE REASONABLY SMOOTH AND UNIFORM. APPLY AGRICULTURAL LIME - AND FERTILIZER UNIFORMLY AND MIX WITH SOIL. CONTINUE TILLAGE UNTIL A WELL PULVERIZED, REASONABLY UNIFORM SEEDBED IS PREPARED 4" TO 6" DEEP. SPREAD SEED ON FRESHLY PREPARED SEEDBED AND COVER LIGHTLY WITH SEEDING EQUIPMENT OR CULTIPACKER AFTER SEEDING. MULCH IMMEDIATELY AFTER SEEDING AND ANCHOR MULCH. HYDROSEEDING: SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDROSEEDING, AS A ROUGHENED SLOPE WILL PROVIDE SOME NATURAL COVERAGE FOR LIME, FERTILIZER, AND SEED. THE SURFACE SHOULD NOT BE COMPACTED OR SMOOTH. FINE SEEDBED PREPARATION IS NOT NECESSARY FOR HYDROSEEDING OPERATIONS: LARGE CLODS, STONES, AND IRREGULARITIES PROVIDE CAVITIES IN WHICH SEEDS CAN LODGE. RATE OF WOOD FIBER (CELLULOSE) APPLICATION SHOULD BE AT LEAST 2,000 LB/ACRE. APPLY LEGUME INOCULANTS AT FOUR TIMES THE RECOMMENDED RATE WHEN ADDING INOCULANT TO A HYDROSEEDER SLURRY. IF A MACHINERY BREAKDOWN OF )j TO 2 HOURS OCCURS, ADD 50% MORE SEED TO THE TASK, BASED ON THE PROPORTION OF THE SLURRY REMAINING. THIS SHOULD COMPENSATE FOR DAMAGE TO SEED. BEYOND 2 HOURS, FULL RATE OF NEW SEED MAY BE NECESSARY. LIME IS NOT NORMALLY APPLIED WITH A HYDRAULIC SEEDER BECAUSE IT IS ABRASIVE. IT CAN BE BLOWN ONTO STEEP SLOPES IN DRY FORM. CRIMPING STRAW MULCH: CRIMPING CAN BE APPLIED TO AREAS ADJACENT TO ANY SECTION OF THE ROADWAY WHERE TRAFFIC IS TO BE MAINTAINED OR ALLOWED DURING CONSTRUCTION. IN AREAS WITHIN SIX FEET OF THE EDGE OF PAVEMENT, STRAW IS TO BE APPLIED AND THEN CRIMPED. AFTER THE CRIMPING OPERATION IS COMPLETE, AN ADDITIONAL APPLICATION OF STRAW SHALL BE APPLIED AND IMMEDIATELY TACKED WITH A SUFFICIENT AMOUNT OF UNDILUTED EMULSIFIED ASPHALT. - STRAW MULCH SHALL BE OF SUFFICIENT LENGHT AND QUALITY TO WITHSTAND THE CRIMPING OPERATION.. - 1 CRIMPING EQUIPMENT INCLUDING POWER SOURCE SHALL BE SUBJECT TO THE APPROVAL OF THE ENGINEER PROVIDING THAT MAXIMUM SPACING OF CRIMPER BLADES SHALL NOT EXCEED 8". j SEEDING SCHEDULE: PERMANENT SEEDING SEEDING MIXTURE SPECIES RATE(LBQ/ACRE) 2 TALL FESCUE 75 COMMON BERMUDA (HULLED) 25 (MARCH) TO AUG 31) COMMON BERMUDA (UNHULLED) 35 (SEPT 1 TO FEB 28) SEEDING DATES BEST POSSIBLE 8/ 25-10/1 2/1-4/15 SOIL AMENDMENTS LIMESTONE 4000 LBS/ACRE FERTILIZER(10-20-20) 500 LB/ACRE STRAW MULCH 4000 LB/ACRE EMULSIFIED ASPHALT TACK 400 GALLON/ACRE ON CUT/FILL SLOPES 2:1 OR STEEPER, ADD 50# OF SERICEA LESPEDEZA FROM JAN 1-DEC 31 TEMPORARY SEEDING j SEEDING MIXTURE WINTER/EARLY SPRING SUMMER i SPECIES RATE(LB/ACRE) RATE(LB/ACRE) RATE( B/ACRE) GERMAN MILLET _ - 50 RYE (GRAIN) 50 50 - SEEDING DATES 12/1-4/15 4/15-8/15 8/15-12/30 SOIL AMENDMENTS LIMESTONE 2000 LB/ACRE 2000 LB/ACRE 2000 LB/ACRE FERTILIZER(10-20-20) 400 LB/ACRE 400 LB/ACRE 400 LB/ACRE STRAW MULCH 4000 LB/ACRE 4000 LB/ACRE 4000 LB/ACRE EMULSIFIED ASPHALT TACK 300 GALLON/ACRE 300 GALLON/ACRE 300 GALLON/ACRE HYDROSEEDING MATERIAL QUANTITY SEED 200 LB/ACRE FERTILIZER 500 LB/ACRE STRAW MULCH 1200 LB/ACRE TACKIFIER 100 LB/ACRE now cA� ice. n ------I'1.1•i MN:, r1 •Nrl 11 IIIIFLOW ,�� IVrrr III IL. .1. •I. rlSy Ii4r�1 �•V •OVERI AP NETTING %\ • I IIII I III `: � •• :�C�iii III �0 ��• �•�III II �� w• GENERAL NOTES: 1.
