WET POND GRADING & PLANTING NOTES:
0 1. ALL PLANTING PROCEDURES SHALL BE DONE IN ACCORDANCE WITH NCDENR STANDARDS.
° 2. ADEQUATE ACCESS MUST BE AVAILABLE FOR INSPECTIONS, MAINTENANCE, AND EQUIPMENT.
3. ALL MAINTENANCE ACTIVITIES SHOULD BE RECORDED. NOTES SHOULD INCLUDE THE DATES AND TYPES OF WORK PERFORMED AS WELL AS WHO PERFORMED THE WORK.
i 4. DEVELOPMENTAL PHASE MAINTENANCE EXTENDS THROUGH 2 TO 5 GROWING SEASONS.
5. INFERTILE SOILS SHOULD BE AMENDED BEFORE INSTALLATION AND THEN FERTILIZED PERIODICALLY THEREAFTER.
£ 6. ACCEPTABLE FERTILIZERS CAN BE: MINERAL, ORGANIC (MANURE), COMPOST OR GREEN CROPS.
Y 7. WEEDING IS OFTEN NECESSARY IN THE FIRST GROWING SEASON, PARTICULARLY IF HERBACEOUS GRASSES AERATE -COMPETING THE YOUNG WOODY VEGETATION GROWTH.
o GRASS SHOULD BE REMOVED TO ABOUT 6" ON ALL SIDES OF THE SOIL BIOENGINEERING ELEMENT. THE NEED FOR WEEDING MAY BE LARGELY ELIMINATED BY MINIMIZING THE
,., AMOUNT OF SEED USED FOR TEMPORARY EROSION CONTROL.
- 8. SOILS SHOULD BE LOOSENED TO A DEPTH OF 6". HARD SOILS MAY REQUIRE DISKING.
.n 9. WHENEVER POSSIBLE, TOPSOIL SHOULD BE SPREAD TO A DEPTH OF 4-10" AND LIGHTLY COMPACTED TO A MINIMUM THICKNESS OF 6".
10. THE OPTIMAL PERIOD FOR TRANSPLANTING EXTENDS FROM EARLY APRIL TO MIDJUNE SO THAT THE PLANTS WILL HAVE A FULL GROWING SEASON TO BUILD THE ROOT
RESERVES NEEDED TO SURVIVE THE WINTER.
5 11. POST -NURSERY CARE OF PLANTS IS VERY IMPORTANT IN THE INTERVAL BETWEEN DELIVERY OF THE PLANTS AND THEIR INSTILLATION BECAUSE THEY ARE PRONE TO
3 DESICCATION. THE STOCK SHOULD BE FREQUENTLY WATERED, FERTILIZED AND SHADED.
a 12. A WET HYDROSEED MIX OR OTHER METHOD SHOULD BE USED TO ESTABLISH VEGETATIVE COVER IN THE POND WITHIN 14 DAYS OF CONSTRUCTION. FOR RAPID GERMINATION,
SCARIFY THE SOIL TO A HALF -INCH PRIOR TO HYDROSEEDING.
13. SEE EROSION AND SEDIMENTATION CONTROL DETAIL SHEETS FOR DESIGN INFORMATION FOR THE CONTROL STRUCTURE, OUTFALL PIPE, AND RIPRAP APRONS.
14. THE OPTIMAL PERIOD FOR TRANSPLANTING EXTENDS FROM EARLY APRIL TO MID-JUNE. CONTRACTOR SHALL ACQUIRE PLANTS FROM A REGIONAL NURSERY, SUCH AS
COASTAL PLAIN CONSERVATION NURSERY, INC. PLANTS SHALL NOT BE HARVESTED FROM WILD POPULATIONS.
v SEEDING INSTALLATION:

0 15. NEWLY GRADED SUBGRADES
SUBGRADE TO DEPTH OF 4
. DISK, DRAG HARROW OR HAND RAKE SUBG
a - BEFORE PLACING TOPSOIL, RAKE SUBSOIL SURFACE CLEAR OF STONES, DEBRIS, AND ROOTS S ,
INCHES AND REMOVE STONES LARGER THAN 1-112 INCHES TO PROVIDE BOND FOR TOPSOIL.
o - SPREAD TOPSOIL TO A DEPTH OF 4 INCHES BUT NOT LESS THAN REQUIRED TO MEET FINISH GRADES AFTER LIGHT ROLLING AND NATURAL SETTLEMENT. ADJUST
E DEPTH OF TOPSOIL IN AREAS ADJACENT TO PAVED SURFACES OR CURBS TO ALLOW FOR THE PLACEMENT OF SOD OR SEED.
° 16. UNCHANGED SUBGRADES: IF AREAS TO BE SEEDED ARE UNALTERED OR UNDISTURBED BY EXCAVATING, GRADING, OR SURFACE -SOIL STRIPPING OPERATIONS, PREPARE
SURFACE AS FOLLOWS:
' REMOVE EXISTING GRASS, VEGETATION, AND TURF. DO NOT MIX INTO SURFACE SOIL.
- DISK, DRAG, OR HARROW SURFACE SOIL TO A DEPTH OF AT LEAST 6 INCHES.
Y - REMOVE STONES LARGER THAT 1-1/2 INCH IN ANY DIMENSION AND STICKS, ROOTS, TRASH, AND OTHER EXTRANEOUS MATTER.
I
a - LEGALLY DISPOSE OF WASTE MATERIAL, INCLUDING GRASS, VEGETATION, AND TURF.
`0 17. INCORPORATE SOIL AMENDMENTS AND COMMERCIAL FERTILIZER INTO THE TOP 41NCHES OF TOPSOIL TO ACHIEVE THE SPECIFIED TOPSOIL REQUIREMENTS. TILL SOIL TO A
;o HOMOGENOUS MIXTURE OF FINE TEXTURE.
¢ 18. GRADE AREAS TO FINISH GRADES, FILLING AS NEEDED OR REMOVING SURPLUS TOPSOIL, FLOAT AREAS TO SMOOTH, UNIFORM GRADE AS INDICATED ON THE DRAWINGS.
v AREAS SHALL SLOPE TO DRAIN.
° 19. WHERE NO GRADES ARE SHOWN, AREAS SHALL HAVE A SMOOTH AND CONTINUAL GRADE BETWEEN EXISTING OR FIXED CONTROLS, SUCH AS WALKS, CURBS, CATCH BASIN,
STEPS, OR BUILDINGS. ROLL, SCARIFY, RAKE, AND LEVEL AS NECESSARY TO OBTAIN TRUE, EVEN LAWN SURFACES. FINISH GRADES SHALL MEET APPROVAL OF OWNER
BEFORE GRASS SEED IS SOWN OR SOD IS PLACED.
L 2 20. SEED BEDS SHALL BE PERMITTED TO SETTLE OR SHALL BE FIRMED BY ROLLING BEFORE SEEDING BEGINS.
21. THE SURFACE OF THE SOIL SHOULD BE LOOSENED JUST BEFORE BROADCASTING THE SEED. SEED SHOULD BE APPLIED EVENLY BY THE MOST CONVENIENT METHOD
'-
0 AVAILABLE FOR THE TYPE OF SEED TO BE USED AND THE LOCATION OF THE TEMPORARY SEEDING. TYPICALLY APPLICATION METHODS INCLUDE BUT ARE NOT LIMITED TO
w CYCLONE SEEDERS, ROTARY SPREADERS, DROP SPREADERS BROADCAST SPREADERS, HAND SPREADERS, CULTIPACKER SEEDER, AND HYDRO -SEEDERS. COVER APPLIED
SEED BY RAKING OR DRAGGING A CHAIN, AND THEN TIGHTLY FIRM THE AREA WITH A ROLLER OR CULTIPACKER. DO NOT ROLL SEED THAT IS APPLIED WITH A HYDRO -SEEDER
i C AND HYDRO -MULCH.
MULCHING
.3 22, ALL PERMANENT SEEDED AREAS SHOULD BE COVERED WITH MULCH IMMEDIATELY UPON COMPLETION OF THE SEEDING APPLICATION TO RETAIN SOIL MOISTURE AND REDUCE
EROSION DURING ESTABLISHMENT OF VEGETATION.
L o' 23. THE MULCH SHOULD BE APPLIED EVENLY IN SUCH A MANNER THAT IT PROVIDES A MINIMUM OF 75% COVERAGE. TYPICAL MULCH APPLICATIONS INCLUDE STRAW, WOOD CHIPS,
r BARK, WOOD FIBER, AND HYDROMULCHES.
' 3 24. THE MOST COMMONLY ACCEPTED MULCH USED IN CONJUNCTION WITH PERMANENT SEEDING IS SMALL GRAIN STRAW. THIS STRAW SHOULD BE DRY AND FREE FROM MOLD
v DAMAGE AND NOXIOUS WEEDS.
q E 25. THE STRAW MAY NEED TO BE ANCHORED WITH NETTING OR ASPHALT EMULSIONS TO PREVENT IT FROM BEING BLOWN OR WASHED AWAY. THE STRAW MULCH MAY BE APPLIED
o BY HAND OR MACHINE AT THE RATE 2 TONS PER ACRE (90 POUNDS PER 1000 SQUARE FEET). FREQUENT INSPECTIONS ARE NECESSARY TO CHECK THAT CONDITIONS FOR
m GROWTH ARE GOOD.
RE -SEEDING
c 26. INSPECT PERMANENTLY SEEDED AREAS FOR FAILURE, MAKE NECESSARY REPAIRS AND RESEED OR OVERSEED WITHIN THE SAME GROWING SEASON IF POSSIBLE.
U `0 27. IF THE GRASS COVER IS SPARSE OR PATCHY, REEVALUATE THE CHOICE OF GRASS AND QUANTITIES OF LIME AND FERTILIZER APPLIED. IF THE PERMANENT SEEDING HAS LESS
° v THAN 40% COVER, HAVE THE SOIL TESTED TO DETERMINE ANY ACIDITY OR NUTRIENT DEFICIENCY PROBLEMS.
28. FINAL STABILIZATION BY PERMANENT SEEDING OF THE SITE REQUIRES THAT IT BE COVERED BY A 70%COVERAGE RATE.
