SOIL PREPARATION ELEMENTS, TEMPORARY AND PERMANENT SEED AND GROUND COVER SHALL BE SPREAD OVER ALL AREAS WITHIN THE LOD THAT ARE DISTURBED DURING CONSTRUCTION. 2. SLOPES STABILIZED WITH FLEXAMAT SHALL RECEIVE THE SAME TEMPORARY AND PERMANENT SEEDING APPLICATION AND RATE AS OTHER DISTURBED RIPARIAN AREAS ON THE SITE. NOT LIVE STAKES OR BARE ROOTS SHALL BE PLANTED THROUGH THE FLEXAMAT. 3. LIVE STAKES, BARE ROOT STOCK AND CONTAINERIZED PLANTS SHALL BE LOCATED WHERE SHOWN ON PLAN. 4. ADJUSTMENTS TO THE VEGETATION PLAN SHALL BE MADE ONLY IF APPROVED BY THE TOWN OR ENGINEER. TEMPORARY SEEDING AND MULCHING 5. ALL SEED AND SEED VARIETIES MUST BE OF FROM STATE AND FEDERALLY LISTED NOXIOUS WEED SEED. 6. ALL DISTURBED AREAS WILL BE SEEDED WITH TEMPORARY SEED AND MULCHED WITH WHEAT STRAW. SEEDING WILL BE PERFORMED USING A BROADCAST SPREADER. OTHER METHODS MAY BE USED BUT MUST BE APPROVED BY ENGINEER IN ADVANCE OF INSTALLATION. 7. MAINTENANCE OF SEEDED AREAS SHALL CONSIST OF WATERING, WEED AND PEST CONTROL, FERTILIZATION, EROSION REPAIR, RESEEDING, AND INCIDENTAL OPERATIONS AS NECESSARY TO ESTABLISH A HEALTHY, VIGOROUS, WEED FREE AND DISEASE FEE UNIFORM STAND OF GRASS. ALL AREAS WHICH FAIL TO SHOW A UNIFORM STAND OF GRASS FOR ANY REASON SHALL BE TREATED REPEATEDLY UNTIL A UNIFORM STAND OF AT LEAST 90% COVERAGE IS ATTAINED WITH NO BARE AREA GREATER THAN FIVE SQUARE FEET. PERMANENT SEEDING 8. PERMANENT SEEDING SHALL OCCUR IN CONJUNCTION WITH TEMPORARY SEEDING WHERE APPLICABLE. IDEALLY, PERMANENT SEEDING SHALL OCCUR DURING THE PLANTING SEASON FOR EACH SEED TYPE.

THE CONTRACTOR SHALL LOOSEN THE SOIL TO A MINIMUM DEPTH OF 4-INCHES AND GRADE TO A SMOOTH, EVEN SURFACE WITH A LOOSE, UNIFORMLY FINE TEXTURE. THE AREAS TO BE SEEDED ARE THEN TO BE ROLLED AND RAKED TO REMOVE RIDGES AND FILL DEPRESSIONS TO MEET FINISH GRADES. THE CONTRACTOR IS TO LIMIT SUB GRADE AND FINISH GRADE PREPARATION TO AREAS THAT WILL BE PLANTED IMMEDIATELY. PREPARED AREAS ARE TO BE RESTORED IF ERODED OR OTHERWISE DISTURBED AFTER FINE GRADING AND BEFORE PLANTING. 11. SEED SHALL BE SOWN WITH A SPREADER OR A SEEDING MACHINE. SEED IS NOT TO BE BROADCAST OR DROPPED WHEN WIND VELOCITY EXCEEDS 5 MPH. SEED SHALL BE EVENLY DISTRIBUTED BY SOWING IN TWO DIRECTIONS AT RIGHT ANGLES TO EACH OTHER. WET SEED OR SEED THAT IS MOLDY OR OTHERWISE DAMAGED IN TRANSIT OR STORAGE IS NOT TO BE USED. AFTER BEGIN SOWN, THE SEED SHALL BE RAKED INTO THE TOP 1/9 INCH OF THE TOPSOIL, LIGHTLY ROLLED, AND WATERED WITH FINE SPRAY. SEEDED AREAS ON STREAM BANKS SHALL BE PROTECTED WITH COIR FIBER MATTING. BARE ROOTS 12. ALLOW BARE ROOTS TO SOAK IN WATER AN HOUR OR TWO BEFORE PLANTING. DO NOT SOAK THE ROOTS FOR MORE THAN 24 HOURS. 13. DIG A PLANTING PIT THAT IS THREE (3) TIMES WIDER THAN THE TREE'S CURRENT ROOT SYSTEM. SPREAD OUT ROOTS TO ENCOURAGE OUTWARD GROWTH. 14. KEEP THE TREE VERTICAL IN THE PLANTING PIT (PERPENDICULAR TO THE GROUND) SO THAT IT GROWS STRAIGHT. 15. REFILL THE PIT WITH NATIVE SOIL (WHAT WAS REMOVED AT DIGGING TIME), AND ANY OTHER SOIL AMENDMENTS. 16. GENTLY TAMP OUT ANY AIR POCKETS FROM THE SOIL ONCE THE PLANTING HOLE IS FILLED. LIVE STAKES 17. LIVE STAKES MUST BE DORMANT WHEN CUT. KEEP LIVE STAKES MOIST UNTIL � LLI m- .ti� O' O� PLANTING. THE STAKE SHOULD BE PREPARED WITH THE BUDS POINTED UP, AND THE BOTTOM SHOULD BE CUT AT AN ANGLE FOR EASY INSERTION INTO THE GROUND. 18.
