PERMANENT SEEDING
PROVIDE PERMANENT SEEDING TO ALL DENUDED AREAS THAT WILL NOT BE COVERED BY PAVING, BUILDINGS, OR OTHER LANDSCAPING
WITHIN THE TIMEFRAME SPECIFIED ON THE STABILIZATION TIMEFRAME TABLE.
COMPLETE GRADING BEFORE PREPARING SEEDBEDS. IF SOILS BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8
INCHES.
SEEDBED REQUIREMENTS:
THE SOIL SHOULD MEET THE FOLLOWING MINIMUM CRITERIA FOR VE=GETATION ESTABLISHMENT:
• ENOUGH FINE - GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE AND NUTRIENT SUPPLY (AVAILABLE WATER
CAPACITY OF AT LEAST 0.05 INCHES OF WATER TO 1 INCH OF SOIL
• SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
• SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH OF ROCK OR IMPERMEABLE LAYERS SUCH AS
HARDPANS SHOULD BE 12 INCHES OR MORE, EXCEPT ON SLOPES STEEPER THAN 2 :1 WHERE THE ADDITION OF SOIL IS NOT
FEASIBLE.
• A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0.6.5.
• NO LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, AND TRASH. CLODS AND STONES MAY BE LEFT ON SLOPES
STEEPER THAN 3:1 IF THEY ARE TO BE HYDROSEEDED.
IF THE ABOVE CRITERIA CANNOT BE MET, SPECIAL SOIL CONDITIONERS OR TOPSOIL MAY BE APPLIED.
SEEDBED PREPARATION:
LIME: APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE SOIL PH IS NOT KNOWN, FOLLOW RATES ON THE SEEDING
SPEC TABLE.
FERTILIZER: FERTILIZE ACCORDING TO SOIL TEST RECOMMENDATIONS. WHERE SOIL TESTS ARE NOT AVAILABLE, FOLLOW RATES ON
THE SEEDING SPEC TABLE.
SURFACE ROUGHENING: IF AREAS TO BE SEEDED BECOME HARDENED, SEALED, OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY
DISKING, RAKING, HARROWING OR OTHER SUITABLE METHODS. GROOVE OR FURROW SLOPES STEEPER THAN 3:1 ON THE CONTOUR
BEFORE SEEDING.
PLANT SELECTION:
SELECT THE APPROPRIATE SPECIES BASED ON THE PLANTING SEASCA, SOIL TYPE, SLOPES, AND LAND USES. SEE SEEDING SPEC
TABLES IN PLANS FOR RECOMMENDED PERMANENT SEEDING MIXTURE.
SEEDING:
USE CERTIFIED SEED (INSPECTED BY THE NORTH CAROLINA CROP IMPROVEMENT ASSOCIATION).
APPLY SEED WITH A BROADCAST SEEDER, DRILL, CULTIPACKER SEEDS :R, OR HYDROSEEDER ON A FIRM, FRIABLE SEEDBED. USE
SEEDING RATES GIVEN IN TABLES.
WHEN USING A DRILL OR CULTIPACKER SEEDER, SMALL GRAINS SHO' _d!LD BE PLANTED NO MORE THAN ONE INCH DEEP AND GRASSES
AND LEGUMES ON MORE THAN Y INCH.
WHEN BROADCAST SEEDING, SUBDIVIDE AREA INTO WORKABLE SECTONS AND DETERMINE THE AMOUNT OF SEED NEEDED FOR EACH
SECTION. APPLY ONE -HALF THE SEED WHILE MOVING BACK AND FORTH ACROSS THE AREA AND APPLY THE REMAINING SEED IN THE
SAME MANNER BUT AT RIGHT ANGLES TO THE FIRST PASS. COVER SEED BY RAKING OR CHAIN DRAGGING, AND THEN LIGHTLY FIRM
WITH A ROLLER OR CULTIPACKER.
MULCH AREAS IMMEDIATELY AFTER SEEDING IN ACCORDANCE WITH RATES GIVEN IN TABLES. USE A MINIMUM RATE OF 4,000 LB /ACRE.
HYDROSEEDING:
SURFACE ROUGHENING IS REQUIRED. FINE SEEDBED PREPARATION IS NOT NECESSARY.
RATE OF WOOD FIBER APPLICATION SHOULD BE AT LEAST 4,000- 6,000 LB /ACRE.
APPLY LEGUME INOCULANTS AT FOUR TIMES THE RECOMMENDED RAT E WHEN ADDING INOCULANT TO HYDROSEEDER SLURRY.

IRRIGATION:
IRRIGATE DURING DRY PERIODS OR TO SPEED DEVELOPMENT OF FUG`- COVER.
MAINTENANCE:
IF STAND IS INADEQUATE, RE- EVALUATE PLANT CHOICE AND QUANTITI ES OF LIME AND FERTILIZER. REESTABLISH THE STAND AFTER
SEEDBED PREPARATION OR OVER -SEED THE STAND. CONSIDER SEE`=:lNG TEMPORARY, ANNUAL SPECIES IF THE TIME OF YEAR IS NOT

TEMPORARY SEEDING
PROVIDE TEMPORARY SEEDING TO ALL DENUDED AREAS THAT WILL NOT BE BROUGHT TO FINAL GRADE WITHIN THE TIMEFRAME SPECIFIED IN THE
TABLE BELOW.
COMPLETE GRADING BEFORE PREPARII4G SEEDBEDS. IF SOILS BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8 INCHES.
SEEDBED PREPARATION:
LIME: APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE SOIL PH IS NOT KNOWN, APPLY AT A RATE OF 1 TO 1 %z TONS PER
ACRE ON COARSE - TEXTURED SOILS AND 2 -3 TONS PER ACRE OF FINE - TEXTURED SOILS. APPLY LIME UNIFORMLY AND INCORPORATE INTO THE
TOP 4 -6 INCHES OF SOIL. SOILS, WITH PH HIGHER THAN 6 DO NOT NEED LIME.
FERTILIZER: FERTILIZE ACCORIDING TO SOIL TEST RECOMMENDATIONS. WHERE SOIL TESTS ARE NOT AVAILABLE, APPLY A 10 -10-10 GRADE
FERTILIZER AT 700 -1,000 LB /ACEtE. INCORPORATE FERTILIZER INTO THE TOP 4-6 INCHES OF SOIL. IF A HYDRAULIC SEEDER IS USED, DO NOT
MIX SEED AND FERTILIZER MOF:c THAN 30 MINUTES BEFORE APPLICATION.
SURFACE ROUGHENING: IF AREAS TO BE SEEDED BECOME HARDENED, SEALED, OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY
DISKING, RAKING, HARROWING OR OTHER SUITABLE METHODS. GROOVE OR FURROW SLOPES STEEPER THAN 3:1 ON THE CONTOUR BEFORE
SEEDING.
PLANT SELECTION:
SELECT THE APPROPRIATE SPECIES BASED ON THE PLANTING SEASON.
SEEDING:
APPLY SEED WITH A BROADCAST SEEDER, DRILL, CULTIPACKER SEEDER, OR HYDROSEEDER. USE SEEDING RATES GIVEN IN TABLES.
BROADCAST SEEDING AND HYDROSEEDING IS ACCEPTABLE ON STEEP SLOPES WHERE EQUIPMENT CANNOT BE DRIVEN. HAND
BROADCASTING IS NOT RECOMMENDED.
SMALL GRAINS SHOULD BE PLANTED NO MORE THAN ONE INCH DEEP AND GRASSES AND LEGUMES ON MORE THAN % INCH. BROADCAST SEED
MUST BE COVERED BY RAKING OR CHAIN DRAGGING, AND THEN LIGHTLY FIRMED WITH A ROLLER OR CULTIPACKER. HYDROSEEDED MIXTURES
SHOULD NOT INCLUDE A WOOD I=1BER MULCH.
MULCHING:
MULCHING IS REQUIRED UNDER TFriE FOLLOWING CONDITIONS:
• SEEDING IN FALL (WOOD hABER MULCHES NOT ACCEPTABLE)
• SLOPES STEEPER THAN 31
• EXCESSIVELY HOT OR DR "?' WEATHER
e ADVERSE SOILS (SHALLOW, ROCKY, OR HIGH IN CLAY OR SAND)

MAINTENANCE PLAN
THE CONTRACTOR IS RESPONSIBLE FOR MAINTAINING EROSION CONTROL DEVICES THROUGHOUT THE PROJECT DURATION.
ALL EROSION AND SEDIMENT CONTROL DEVICES SHALL BE CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY RUNOFF- PRODUCING
RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS SHALL BE MADE IMMEDIATELY TO MAINTAIN ALL DEVICES AS
DESIGNED.
SEDIMENT TRAPS:
1. SEDIMENT TRAPS ARE TO BE CLEANED OF SEDIMENT WHEN ITS STORAGE CAPACITY IS REDUCED BY 50 %. AFTER CLEANING SEDIMENT,
RESTORE TRAP TO ORIGINAL DIMENSIONS.
2. REPLACE GRAVEL ON THE ROCK SPILLWAY THAT IS IMPAIRED BY SEDIMENT.
3. CHECK STRUCTURE EVERY WEEK FOR EROSION AND PIPING
4. PERIODICALLY CHECK THE DEPTH OF THE SPILLWAY TO ENSURE IT IS A MINIMUM OF 1.5 FEET BELOW THE LOW POINT OF THE EMBANKMENT.
IMMEDIATELY FILL ANY SETTLEMENT OF THE EMBANKMENT TO SLIGHTLY ABOVE DESIGN GRADE.
5. ANY RIP RAP DISPLACED FROM SPILLWAY MUST BE REPLACED IMMEDIATELY.
6. AFTER ALL AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE TRAP AND ALL UNSTABLE SEDIMENT. GRADE ACCORDING TO GRADING
PLAN OR BLEND IN WITH ADJACENT GRADES - ADDITIONAL COMPACTION EFFORTS MAY BE REQUIRED IF STRUCTURE IS PROPOSED
OVERTOP AREA. STABILIZE AREA.
BAFFLES:
1. MAINTAIN ACCESS TO BAFFLES. SHOULD THE FABRIC COLLAPSE, DECOMPOSE, TEAR, OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
2. REMOVE BUILDUP SEDIMENT WHEN IT REACHES ONE -HALF FULL. TAKE CARE NOT TO DISTURB BAFFLES DURING CLEANOUT.
SILT FENCE:
2. SEDIMENT SHALL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES ABOUT 0.5 FT DEEP AT THE FENCE. THE FENCE
SHALL BE REPAIRED AS REQUIRED TO MAINTAIN A SUFFICIENT BARRIER.
3. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, DECOMPOSE, TEAR, OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
4. AFTER ALL AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT. GRADE AREA TO
GRADING PLAN OR BLEND WITH ADJACENT GRADES. STABILIZE AREA.
CONSTRUCTION ENTRANCE:
1. MAINTAIN GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC
TOP DRESSING WITH 2 4NCH STONE.
2. IMMEDIATELY REMOVE ALL MATERIALS SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS.
TEMPORARY DIVERSIONS:
1. IMMEDIATELY REMOVE EXCESS SEDIMENT FROM FLOW AREA AND REPAIR DIVERSION RIDGE.
2. CAREFULLY CHECK OUTLETS AND MAKE TIMELY REPAIRS AS NEEDED.
3. AFTER ALL AREAS HAVE BEEN STABILIZED REMOVE THE RIDGE AND THE CHANNEL AND GRADE ACCORDING TO GRADING PLAN OR BLEND
WITH ADJACENT GRADES. STABILIZE AREA.
RIP RAP LINED DITCHES /CHANNELS /OUTLETS:
1. PAY CLOSE ATTENTION TO INLET AND OUTLET SECTIONS WHERE CONCENTRATED FLOW ENTERS.
2. INSPECT FOR INDICATIONS OF PIPING, SCOUR HOLES, OR BANK FAILURES. MAKE REPAIRS IMMEDIATELY.
3. MAINTAIN VEGETATION ADJACENT TO THE ROCK LINING IN A HEALTHY, VIGOROUS CONDITION TO PROTECT THE AREA FROM EROSION AND
SCOUR.
GRASS LINED DITCHES /CHANNELS /SWALES:
1. DURING GRASS ESTABLISHMENT PERIOD, INSPECT AFTER EVERY RAINFALL.
2. AFTER GRASS HAS ESTABLISHED, INSPECT PERIODICALLY AND AFTER HEAVY RAINFALL. IMMEDIATELY MAKE REPAIRS.
3. PAY CLOSE ATTENTION TO INLET AND OUTLET SECTIONS WHERE CONCENTRATED FLOW ENTERS.
4. GRASS SHOULD BE MAINTAINED IN A HEALTHY VIGOROUS CONDITION AT ALL TIMES, SINCE IT IS THE PRIMARY EROSION PROTECTION.
