PROJECT DESCRIPTION
THE PROPOSED AREA OF CONSTRUCTION WILL INCLUDE: THE REMOVAL OF TREES AND WOODY VEGETATION, THE
INSTALLATION OF TWO (2) PERMANENT CULVERTS WITHIN THE RAILROAD BRANCH CREEK, THE PLACEMENT OF A PERMANENT
ACCESS ROAD, AND THE INSTALLATION OF REQUIRED EROSION/SEDIMENT CONTROL MEASURES. THE ACCESS ROAD WILL BE
USED TO DELIVER EQUIPMENT AND MATERIALS TO CONSTRUCT THE PREVIOUSLY APPROVED SCARP REPAIR ALONG THE NORTH
BANK OF THE DAN RIVER. THE TOTAL PROPOSED CLEARING AREA (DISTURBED AREA) IS APPROXIMATELY 1.34 ACRE.
EROSION AND SEDIMENTATION CONTROL NARRATIVE
THE EROSION AND SEDIMENT CONTROL MEASURES FOR THIS PROJECT INVOLVE THE PLACEMENT OF A VARIETY OF EROSION
AND SEDIMENT CONTROL MEASURES AT STRATEGIC LOCATIONS THROUGHOUT THE DEVELOPMENT. THESE MEASURES
A INCLUDE:
1. FILTREXX SOXX (OR EQUIVALENT)
2. TEMPORARY CONSTRUCTION ENTRANCES
3. PERMANENT SEED
THESE MEASURES ARE TO BE INSTALLED PRIOR TO CLEARING. ALL EROSION CONTROL MEASURES SHALL BE PROPERLY
MAINTAINED UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES AND ALL DISTURBED AREAS HAVE BEEN STABILIZED.
ADDITIONAL CONTROL MEASURES MAY BE REQUIRED DURING CONSTRUCTION IN ORDER TO CONTROL EROSION AND/OR
OFFSITE SEDIMENTATION. ALL TEMPORARY CONTROL MEASURES SHALL BE REMOVED ONCE CONSTRUCTION IS COMPLETE
AND THE SITE IS STABILIZED.
EROSION CONTROL MEASURE NOTES
1. TEMPORARY CULVERTS WILL BE INSTALLED AT TWO (2) LOCATIONS WITHIN THE RAILROAD BRANCH CREEK. THE
INSTALLATION OF THESE CULVERTS WILL BE PERMITTED BY THE USACE AND NCDEQ THROUGH A PCN #39.
2. THE EXISTING, GRAVEL ACCESS ROAD ALONG THE CREST OF THE ADJACENT DIKE WILL SERVE AS THE ACCESS POINT FOR
THE PROJECT, AND AS THE CONSTRUCTION ENTRANCE.
3. PLACE FILTREXX SOXX (OR EQUIVALENT) DOWN -GRADIENT OF THE CONSTRUCTION AREA AS NOTED ON THE PLANS AND AS
INDICATED IN THE DETAILS.
4. EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND MAINTAINED PER THE LATEST VERSION OF
NCDEQ "EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL."
GENERAL NOTES
1. ALL EROSION CONTROL MEASURES SHALL BE PROPERLY MAINTAINED DURING CONSTRUCTION UNTIL THE COMPLETION OF

DEFINITION
CONTROLLING RUNOFF AND EROSION ON DISTURBED AREAS BY ESTABLISHING PERENNIAL
VEGETATIVE COVER WITH SEED.
PURPOSE
TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS, AND TO
PERMANENTLY STABILIZE SUCH AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTS TO SITE
CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIATE PLANT MATERIALS.
SPECIFICATIONS
SEEDBED REQUIREMENTS
ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON SITES THAT ARE
UNSUITABLE DUE TO EXCESSIVE SOIL COMPACTION, INAPPROPRIATE SOIL TEXTURE, POOR
DRAINAGE, CONCENTRATED OVERLAND FLOW, OR STEEPNESS OF SLOPE UNTIL MEASURES
HAVE BEEN TAKEN TO CORRECT THESE PROBLEMS.
TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET CERTAIN MINIMUM
REQUIREMENTS AS A GROWTH MEDIUM. THE EXISTING SOIL SHOULD HAVE THESE CRITERIA:
• ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE
AND NUTRIENT SUPPLY (AVAILABLE WATER CAPACITY OF AT LEAST .05 INCHES 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 TO 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.
• FREE FROM LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, OR TRASH OF
ANY KIND. CLODS AND STONES MAY BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY ARE
TO BE HYDRO SEEDED.
IF ANY OF THE ABOVE CRITERIA ARE NOT MET - I.E., IF EXISTING SOIL IS TOO COARSE, DENSE,
SHALLOW OR ACIDIC TO FOSTER VEGETATION - SPECIAL AMENDMENTS ARE REQUIRED. THE
SOIL CONDITIONERS DESCRIBED BELOW MAY BE BENEFICIAL OR, PREFERABLY, TOPSOIL MAY
BE APPLIED.
SEEDBED PREPARATION
INSTALL NECESSARY MECHANICAL EROSION AND SEDIMENTATION CONTROL PRACTICES
BEFORE SEEDING, AND COMPLETE GRADING ACCORDING TO THE APPROVED PLAN.
LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY SOIL TESTS. DIRECTIONS, SAMPLE
CARTONS, AND INFORMATION SHEETS ARE AVAILABLE THROUGH COUNTY AGRICULTURAL
EXTENSION OFFICES. TESTING IS ALSO DONE BY COMMERCIAL LABORATORIES.
WHEN SOIL TESTS RESULTS ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED IN THE
SEEDING SPECIFICATIONS SHOWN AT RIGHT. APPLICATION RATES USUALLY FALL INTO THE
FOLLOWING RANGES:
�e1:Z�1�1►1�1_Lell[�1�1���L'7_1����ilx.�l�l►1:
LIGHT -TEXTURED, SANDY SOILS: 1-1/2 TONS/ACRE
HEAVY -TEXTURED, CLAYEY SOILS: 2-3 TONS/ACRE
• FERTILIZER:
GRASSES: 800-1200 LB/ACRE OF 10-10-10 (OR THE EQUIVALENT)
GRASS -LEGUME MIXTURES: 800-1200 LB/ACRE OF 10-10-10 (OR THE EQUIVALENT)
APPLY LIME AND FERTILIZER EVENLY AND INCORPORATE INTO THE TOP 4-6 INCHES OF SOIL BY
DISKING OR OTHER SUITABLE MEANS. OPERATE MACHINERY ON THE CONTOUR. WHEN USING
A HYDRO SEEDER, APPLY LIME AND FERTILIZER TO A ROUGH, LOOSE SURFACE.
0911.11111 >�Y�L1y�Ly�y,:1[�l iri>�y�q�11►[e
COMPLETE SEEDBED PREPARATION BY BREAKING UP LARGE CLODS AND RAKING INTO A
SMOOTH, UNIFORM SURFACE (SLOPES LESS THAN 3:1). FILL IN OR LEVEL DEPRESSIONS THAT
CAN COLLECT WATER. BROADCAST SEED INTO A FRESHLY LOOSENED SEEDBED THAT HAS
NOT BEEN SEALED BY RAINFALL.
SEEDING
SEEDING DATES GIVEN IN THE SEEDING MIXTURE SPECIFICATIONS ARE DESIGNATED AS
"BEST" OR "POSSIBLE". SEEDINGS PROPERLY CARRIED OUT WITHIN THE "BEST" DATES HAVE A
HIGH PROBABILITY OF SUCCESS. IT IS ALSO POSSIBLE TO HAVE SATISFACTORY
ESTABLISHMENT WHEN SEEDING OUTSIDE THESE DATES. HOWEVER, AS YOU DEVIATE FROM
THEM, THE PROBABILITY OF FAILURE INCREASES RAPIDLY. SEEDING ON THE LAST DATE
SHOWN UNDER "POSSIBLE" MAY REDUCE CHANGES OF SUCCESS BY 30-50%. ALWAYS TAKE
THIS INTO ACCOUNT IN SCHEDULING LAND -DISTURBING ACTIVITIES.
USE CERTIFIED SEED FOR PERMANENT SEEDING WHENEVER POSSIBLE
LABELING OF NON -CERTIFIED SEED IS ALSO REQUIRED BY LAW. LABELS CONTAIN IMPORTANT
INFORMATION ON SEED PURITY, GERMINATION, AND PRESENCE OF WOOD SEEDS. SEEDS
MUST MEET STATE STANDARDS FOR CONTENT OF NOXIOUS WEEDS. DO NO ACCEPT SEED
CONTAINING "PROHIBITED" NOXIOUS WEED SEED.
INOCULATE LEGUME SEED WITH THE RHIZOBIUM BACTERIA APPROPRIATE TO THE SPECIES OF
LEGUME.
APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP -TYPE SPREADER, DRILL,
CULTIPACKER SEEDER, OR HYDRO SEEDER ON A FIRM, FRIABLE SEEDBED.
4 5
REV I DATE I JOB NO
6 7 8
WHEN USING A DRILL OR CULTIPACKER SEEDER, PLANT SMALL GRAINS NO MORE THAN 1 INCH
DEEP, GRASSES AND LEGUMES NO MORE THAN 1/2 INCH. EQUIPMENT SHOULD BE
CALIBRATED IN THE FIELD FOR THE DESIRED SEEDING RATE.
WHEN USING BROADCAST -SEEDING METHODS, SUBDIVIDE THE AREA INTO WORKABLE
SECTIONS AND DETERMINE THE AMOUNT OF SEED NEEDED FOR EACH SECTION. APPLY
ONE-HALF THE SEED WHILE MOVING BACK AND FORTH ACROSS THE AREA, MAKING A UNIFORM
PATTERN: THEN APPLY THE SECOND HALF IN THE SAME WAY, BUT MOVING AT RIGHT ANGLES
TO THE FIRST PASS.
JDJto] :I_1In,IlL::10[eZ11TAI►TAI:011101MAN:01Ill a::4:Z.yMIMI1]10
HYDRO SEEDING
SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDRO SEEDING, 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 HYDRO SEEDING 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 HYDRO SEEDER SLURRY.
IF A MACHINERY BREAKDOWN OF 1/2 TO 2 HOURS OCCURS, ADD 50% MORE SEED TO THE
TANK, BASED ON THE PROPORTION OF THE SLURRY REMAINING. THIS SHOULD COMPENSATE
FOR DAMAGE TO SEED. BEYOND 2 HOURS, A 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.
MAINTENANCE
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTABLISHED
UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING. INSPECT
SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS AND RESEEDINGS WITHIN THE
SAME SEASON, IF POSSIBLE.
RESEEDING --IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF PLANT
MATERIALS AND QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH THE STAND AFTER
SEEDBED PREPARATION OR OVER- SEED THE STAND. CONSIDER SEEDING TEMPORARY,
ANNUAL SPECIES IF THE TIME OF YEAR IS NOT APPROPRIATE FOR PERMANENT SEEDING.
IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF ACIDITY OR
NUTRIENT IMBALANCE IS RESPONSIBLE.
FERTILIZATION --ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT USUALLY REQUIRES
RE -FERTILIZATION IN THE SECOND GROWING SEASON. FINE TURF REQUIRES ANNUAL
MAINTENANCE FERTILIZATION. USE SOIL TESTS IF POSSIBLE OR FOLLOW THE GUIDELINES
GIVEN FOR THE SPECIFIC SEEDING MIXTURE.

DESCRIPTION
THE WORK SHOULD CONSIST OF INSTALLING A TEMPORARY PUMP AROUND AND SUPPORTING MEASURES
TO DIVERT FLOW AROUND IN -STREAM CONSTRUCTION SITES.
IMPLEMENTATION SEQUENCE
SEDIMENT CONTROL MEASURES, PUMP -AROUND PRACTICES, AND ASSOCIATED CHANNEL AND BANK
CONSTRUCTION
SHOULD BE COMPLETED IN THE FOLLOWING SEQUENCE:
1. CONSTRUCTION SHOULD NOT BEGIN UNTIL ALL SEDIMENT AND EROSION CONTROL MEASURES
HAVE BEEN INSTALLED. THE CONTRACTOR SHOULD STAY WITHIN THE LIMITS OF THE
DISTURBANCE AS SHOWN ON THE PLANS AND MINIMIZE DISTURBANCE WITHIN THE WORK AREA
WHENEVER POSSIBLE.
2 UPON INSTALLATION OF ALL SEDIMENT CONTROL MEASURES, THE CONTRACTOR SHOULD BEGIN
WORK AT THE UPSTREAM SECTION AND PROCEED DOWNSTREAM BEGINNING WITH THE
ESTABLISHMENT OF STABILIZED CONSTRUCTION ENTRANCES. IN SOME CASES, WORK MAY
BEGIN DOWNSTREAM IF APPROPRIATE. WORK SHOULD NOT BE CONDUCTED IN THE CHANNEL
DURING RAIN EVENTS.
3 SANDBAG DIKES SHOULD BE SITUATED AT THE UPSTREAM AND DOWNSTREAM ENDS OF THE
WORK AREA AS SHOWN ON THE PLANS, AND STREAM FLOW SHOULD BE PUMPED AROUND THE
WORK AREA. THE PUMP SHOULD DISCHARGE ONTO A STABLE VELOCITY DISSIPATER MADE OF
RIPRAP OR SANDBAGS.
4 WATER FROM THE WORK AREA SHOULD BE PUMPED TO A SEDIMENT FILTERING MEASURE SUCH
AS A DEWATERING BASIN, SILT BAG, OR OTHER APPROVED SOURCE. THE MEASURE SHOULD BE
LOCATED SUCH THAT THE WATER DRAINS BACK INTO THE CHANNEL BELOW THE DOWNSTREAM
SANDBAG DIKE.
5 THE CONTRACTOR IS RESPONSIBLE FOR PROVIDING ACCESS TO AND MAINTAINING ALL EROSION
AND SEDIMENT CONTROL DEVICES UNTIL THE SEDIMENT CONTROL INSPECTOR APPROVES THEIR
REMOVAL.
6. AFTER CONSTRUCTION, ALL DISTURBED AREAS SHOULD BE REGRADED AND REVEGETATED AS
PER THE PLANTING PLAN.

INSPECTION AND MAINTENANCE NOTES:
1. ALL EROSION AND SEDIMENTATION CONTROL DEVICES AND PLANTED AREAS
SHALL BE INSPECTED EVERY SEVEN (7) CALENDAR DAYS AND AFTER EACH
RAINFALL OCCURRENCE THAT EXCEEDS ONE-HALF (1/2) INCH WITHIN A
24-HOUR PERIOD. DAMAGED OR INEFFECTIVE DEVICES SHALL BE REPAIRED OR
REPLACED, AS NECESSARY, AS SOON AS PRACTICAL.
2. REMOVE ACCUMULATED SEDIMENT WHEN IT REACHES 1/3 THE HEIGHT OF THE
DEVICE.
3. REMOVED SEDIMENT SHALL BE PLACED IN STOCKPILE STORAGE AREAS OR
SPREAD THINLY ACROSS DISTURBED AREA. STABILIZE THE REMOVED
SEDIMENT AFTER IT IS RELOCATED.
4. REMOVE TEMPORARY E&SC MEASURES UPON STABILIZATION OF THE
TRIBUTARY DRAINAGE AREA. REMOVE ALL CONSTRUCTION MATERIAL AND
SEDIMENT, AND DISPOSE OF THEM PROPERLY. COMPOST SOCKS MAY BE
ABANDONED BY CUTTING THE SOCK MATERIAL AND SPREADING THE COMPOST
IN-PLACE. GRADE THE DISTURBED AREA TO DRAIN AND STABILIZE
ACCORDINGLY.
