EROSION AND SEDIMENT CONTROL NARRATIVE
PROJECT DESCRIPTION: THIS PLAN PROPOSES THE CONSTRUCTION OF AN ALL-WEATHER
ROAD FOR CONSTRUCTION AND MAINTENANCE OF AN EEL LADDER AT THE DOWNSTREAM
SIDE OF THE LAKE GASTON NORTH END OF THE DAM. APPROXIMATELY, 2.65 ACRES WILL BE
DISTURBED DURING CONSTRUCTION.
EXISTING SITE CONDITIONS: THE EXISTING SITE CONSISTS OF LARGE GRASS AREAS,
WOODED AREAS, AND RIPRAP AROUND THE PERIMETER OF THE ROAD. SLOPES
RANGE FROM 2% TO 33% IN THE AREA OF CONSTRUCTION. THERE ARE NO
PROPOSED TREE SAVE AREAS WITHIN THE CONSTRUCTION LIMITS. WETLAND AREAS
HAVE BEEN SHOWN AND WILL NOT BE UNNECESSARILY DISTURBED.
ADJACENT AREAS: TO THE NORTH OF THE SITE IS FORESTED DOMINION LAND. TO
THE WEST IS A DAM. ON THE SOUTH SIDE IS LAKE GASTON. TO THE EAST IS
FORESTED DOMINION LAND, WETLANDS, AND LAKE GASTON.
OFFSITE AREAS: THERE WILL BE NO OFFSITE DISTURBANCE WITH THE CONSTRUCTION OF
THIS SITE.
CRITICAL AREAS: THE SITE CONTAINS WETLANDS AND HYDRIC SOILS. DISTURBANCE WILL BE
MINIMIZED TO THE LIMITS OF DISTURBANCE.
SOILS: SITE SOILS ARE UDORTHENTS, WEHADKEE LOAM, AND PACOLET SANDY CLAY LOAM
SEE SOILS MAP ON SHEETS 5.0-6.1.
EROSION AND SEDIMENT CONTROL FOR THE PROPOSED CONSTRUCTION ACTIVITIES WILL BE
IN ACCORDANCE WITH POLICIES AND REQUIREMENTS OF THE NORTH CAROLINA EROSION
AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL.
SEDIMENT CONTROL WILL BE ACCOMPLISHED THROUGH RAPID STABILIZATION AND BY THE
INSTALLATION OF MECHANICAL DEVICES, INCLUDING A TEMPORARY GRAVEL CONSTRUCTION
ENTRANCE (CE), SEDIMENT FENCE (SF), ROCK PIPE INLET PROTECTION (PIP), TURBIDITY
CURTAIN TC AND OUTLET STABILIZATION STRUCTURE (OS). ALL SEDIMENT CONTROL
MEASURES ARE INTENDED TO PREVENT SEDIMENT FROM ENCROACHING ONTO ADJACENT
PROPERTIES AND NATURAL WATER COURSES.
INSTALLATION SCHEDULE:
PHASE I OPERATIONS ARE TO CONTROL EROSION AND SEDIMENT ASSOCIATED WITH INITIAL
CLEARING AND GRADING.
1. OBTAIN CONSTRUCTION PERMIT AND ATTEND PRE CONSTRUCTION MEETING WITH THE
INSPECTOR PRIOR TO STARTING ANY LAND DISTURBING ACTIVITIES.
2. INSTALL STABILIZED CONSTRUCTION ENTRANCE. MUD AND DEBRIS SHALL BE WASHED
FROM ALL CONSTRUCTION VEHICLES AND EQUIPMENT BEFORE LEAVING THE SITE.
WATER TANKS WILL BE USED IF PUBLIC WATER IS NOT AVAILABLE.
3. CLEAR AND GRUB ONLY THE AREAS NECESSARY TO INSTALL PHASE I CONTROL
MEASURES. INSTALL CONSTRUCTION ENTRANCE, SEDIMENT FENCES, ROCK PIPE INLET
PROTECTION, OUTLET STABILIZATION STRUCTURE, AND TURBIDITY CURTAIN. SEDIMENT
FENCES WILL ALSO SERVE AS TREE PROTECTION, WHERE APPLICABLE. SF SHALL BE
INSTALLED BY TRENCHING WHICH WILL SERVE AS ROOT PRUNING.
4. OBTAIN PHASE I EROSION AND SEDIMENT CONTROL APPROVAL AND PERMIT BEFORE
PROCEEDING WITH THE PHASE II CONTROLS.
5. SF SHALL BE INSTALLED AROUND WETLAND AREAS INTENDED TO BE PROTECTED.
PHASE II SEDIMENT CONTROL MEASURES ARE INTENDED TO PROVIDE CONTROL DURING THE
FINAL STAGES OF SITE DEVELOPMENT. PHASE I CONTROL MEASURES, WHICH ARE NOT IN
CONFLICT WITH FINAL CONSTRUCTION AND PROVIDE EFFECTIVE CONTROL, ARE TO REMAIN
IN PLACE UNTIL SITE IS PROPERLY STABILIZED.
1. CLEAR AND GRUB THE REMAINDER OF THE SITE
2. APPLY TEMPORARY OR PERMANENT SEEDING TO ALL DENUDED AREAS AS EARTHWORK
OPERATIONS PROGRESS.
3. DEMOLISH/REMOVE REMAINING ITEMS SHOWN ON THE EXISTING CONDITIONS AND
DEMOLITION PLAN.
4. ROUGH GRADE THE SITE.
5. FINE GRADE TO SUBGRADE ELEVATION AND INSTALL GRAVEL SURFACE.
6. INSTALL PERMANENT SEEDING AND MULCHING.
7. ONCE ALL THE SURFACES HAVE BEEN STABILIZED AND PERMISSION HAS BEEN GRANTED
FROM THE SITE INSPECTOR, REMOVE THE EROSION AND SEDIMENT CONTROL
MEASURES WITHIN 30 DAYS.
GENERAL LAND CONSERVATION NOTES
1. NO DISTURBED AREA WHICH IS NOT ACTIVELY BEING WORKED SHALL REMAIN DENUDED FOR MORE
THAN 21 CALENDAR DAYS UNLESS OTHERWISE AUTHORIZED BY THE DIRECTOR.
2. ALL E&S CONTROL MEASURES APPROVED WITH THE PHASE I E&S CONTROL PLAN SHALL BE
PLACED AS THE FIRST STEP IN GRADING.
3. ALL TEMPORARY EARTH BERMS, DIVERSIONS AND SEDIMENT CONTROL DAMS SHALL BE SEEDED
AND MULCHED FOR TEMPORARY VEGETATIVE COVER IMMEDIATELY (AS SOON AS POSSIBLE BUT
NO LATER THAN 48 HOURS) AFTER COMPLETION OF GRADING. STRAW OR HAY MULCH IS
REQUIRED. ALL SOIL STOCKPILES SHALL BE SEEDED AND MULCHED WITHIN 21 DAYS AFTER
GRADING.
4. ANY DISTURBED AREA NOT COVERED BY ITEM NUMBER 1 ABOVE AND NOT PAVED, SODDED OR
BUILT UPON BY NOVEMBER 1, OR DISTURBED AFTER THAT DATE, SHALL BE MULCHED IMMEDIATELY
WITH HAY OR STRAW MULCH AT THE RATE OF 2 TONS/ACRE AND OVER -SEEDED BY APRIL 15.
5. AT THE COMPLETION OF ANY PROJECT CONSTRUCTION AND PRIOR TO BOND RELEASE, ALL
TEMPORARY SEDIMENT CONTROLS SHALL BE REMOVED AND ALL DENUDED AREAS SHALL BE
STABILIZED.
MAINTENANCE OF EROSION AND SEDIMENT CONTROL
MEASURES
THE CONTRACTOR SHALL INSPECT ALL EROSION AND SEDIMENT CONTROL MEASURES DAILY AND
AFTER EACH SIGNIFICANT RAINFALL. ANY NECESSARY REPAIRS OR CLEANUP TO MAINTAIN THE
EFFECTIVENESS OF THE EROSION CONTROL DEVICES MUST BE MADE IMMEDIATELY AFTER THE
INSPECTION. THE FOLLOWING ITEMS WILL BE CHECKED (IF APPLICABLE) IN PARTICULAR:
6.55 ROCK PIPE INLET PROTECTION
INSPECT ROCK PIPE INLET PROTECTION AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT
INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE
THE SEDIMENT STORAGE AREA TO ITS ORIGINAL DIMENSIONS WHEN THE SEDIMENT HAS
ACCUMULATED TO ONE-HALF THE DESIGN DEPTH OF THE TRAP. PLACE THE SEDIMENT THAT IS
REMOVED IN THE DESIGNATED DISPOSAL AREA AND REPLACE THE CONTAMINATED PART OF THE
GRAVEL FACING. CHECK THE STRUCTURE FOR DAMAGE. ANY RIPRAP DISPLACED FROM THE STONE
HORSESHOE MUST BE REPLACED IMMEDIATELY. AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE
BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE AND ALL THE UNSTABLE SEDIMENT.
SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND PROVIDE PERMANENT GROUND
COVER.
6.62 SEDIMENT FENCE
INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAIN FALL MAKE ANY
REQUIRED REPAIRS IMMEDIATELY. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR,
DECOMPOSE OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY. REMOVE SEDIMENT DEPOSITS AS
NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT.
REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO
GRADE AND STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY
STABILIZED.
6.06 CONSTRUCTION ENTRANCE
MAINTAIN THE GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM
LEAVING THE CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOPDRESSING WITH 2-
INCH STONE. AFTER EACH RAINFALL, INSPECT ANY STRUCTURE USED TO TRAP SEDIMENT
AND CLEAN IT OUT AS NECESSARY. IMMEDIATELY REMOVE ALL OBJECTIONABLE MATERIALS
SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS.
6.24 PERMANENT SEEDING
MANY OF THE RECOMMENDED PERMANENT GRASS SPECIES MAY REQUIRE TWO
YEARS FOR ESTABLISHMENT, DEPENDING ON SITE CONDITIONS. INSPECT SEEDED
AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS, SOIL AMENDMENTS, AND
RESEEDINGS. IF WEEDY EXOTIC SPECIES HAVE OVERTAKEN THE AREA AFTER THE
FIRST GROWING SEASON, THE INVADING SPECIES MUST BE ERADICATED TO ALLOW
NATIVE SPECIES TO GROW. NATIVE VEGETATIONS ARE DIFFICULT TO MANAGE AND
TAKE LONGER TO ESTABLISH. MONITOR THE SITE UNTIL LONG TERM STABILITY HAS
BEEN ESTABLISHED.
6.41 OUTLET PROTECTION
INSPECT RIPRAP OUTLETSTRUCTURES WEEKLY AND AFTERSIGNIFICANT (1/2 INCH OR GREATER)
RAINFALL EVENTS TO SEE IF ANY EROSION AROUND OR BELOW THE RIPRAP HAS TAKEN PLACE,
OR IF STONES HAVE BEEN DISLODGED. IMMEDIATELY MAKE ALL NEEDED REPAIRS TO
PREVENT FURTHER DAMAGE.
SOIL STABILIZATION
TEMPORARY SEEDING
TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS THAT MAY NOT BE AT
FINAL GRADE FOR LONGER THAN SEVEN (21) DAYS.
1. SEEDING AND SELECTION OF SEED MIXTURE SHALL BE IN ACCORDANCE WITH THE NORTH
CAROLINA EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL
SPECIFICATION 6.10.
2. SELECT AN APPROPRIATE SPECIES OR SPECIES MIXTURE FROM TABLE 6.10A FOR SEEDING IN
LATE WINTER AND EARLY SPRING, TABLE 6.10B FOR SUMMER, AND TABLE 6.10C FOR FALL.
3. APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE PH (ACIDITY) OF THE SOIL
IS NOT KNOWN, AN APPLICATION OF GROUND AGRICULTURAL LIMESTONE AT THE RATE OF 1
TO 1 1/2 TONS/ACRE ON COARSE -TEXTURED SOILS AND 2-3 TONS/ACRE ON FINE -TEXTURED
SOILS IS USUALLY SUFFICIENT. APPLY LIMESTONE UNIFORMLY AND INCORPORATE INTO THE
TOP 4-6 INCHES OF SOIL. SOILS WITH A PH OF 6 OR HIGHER NEED NOT BE LIMED.
4. BASE APPLICATION RATES ON SOIL TESTS. WHEN THESE ARE NOT POSSIBLE, APPLY A
10-10-10 GRADE FERTILIZER AT 700-1,000 LB/ACRE. BOTH FERTILIZER AND LIME SHOULD BE
INCORPORATED INTO THE TOP 4-6 INCHES OF SOIL. IF A HYDRAULIC SEEDER IS USED, DO NOT
MIX SEED AND FERTILIZER MORE THAN 30 MINUTES BEFORE APPLICATION.
5. S RFACE RO GHENING IF RECENT TILLAGE OPERATIONS HAVE RES LTED IN A LOOSE
SURFACE, ADDITIONAL ROUGHENING MAY NOT BE REQUIRED, EXCEPT TO BREAK UP LARGE
CLODS. IF RAINFALL CAUSES THE SURFACE TO BECOME 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
(PRACTICE 6.03, SURFACE ROUGHENING).
6. SMALL GRAINS SHOULD BE PLANTED NO MORE THAN 1 INCH DEEP, AND GRASSES AND
LEGUMES NO MORE THAN 1/2 INCH. BROADCAST SEED MUST BE COVERED BY RAKING OR
CHAIN DRAGGING, AND THEN LIGHTLY FIRMED WITH A ROLLER OR CULTIPACKER.
HYDROSEEDED MIXTURES SHOULD INCLUDE A WOOD FIBER (CELLULOSE) MULCH.
7. THE USE OF AN APPROPRIATE MULCH WILL HELP ENSURE ESTABLISHMENT UNDER NORMAL
CONDITIONS, AND IS ESSENTIAL TO SEEDING SUCCESS UNDER HARSH SITE CONDITIONS
(PRACTICE 6.14, MULCHING).
PERMANENT SEEDING
ALL AREAS DISTURBED BY CONSTRUCTION WILL BE STABILIZED WITH PERMANENT SEEDING
IMMEDIATELY FOLLOWING FINISH GRADING.
1. SEEDING AND SELECTION OF SEED MIXTURE SHALL BE IN ACCORDANCE WITH THE NORTH
CAROLINA EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL
SPECIFICATION 6.11 AND APPENDIX 8.02.
2. THE PLANTING SOIL MUST HAVE ENOUGH FINE GRAINED SOIL, SUFFICIENT PORE SPACE,
SUFFICIENT DEPTH AND FREE FROM TOXIC OR EXCESSIVE QUANTITIES OF ROOTS.
MULCHING
1. MULCHING SHALL BE IN ACCORDANCE WITH THE NORTH CAROLINA EROSION AND SEDIMENT
CONTROL PLANNING AND DESIGN MANUAL SPECIFICATION 6.14.
2. MULCH TEMPORARY OR PERMANENT SEEDINGS IMMEDIATELY. AREAS THAT CANNOT BE
SEEDED BECAUSE OF THE SEASON SHOULD BE MULCHED TO PROVIDE TEMPORARY
PROTECTION OF THE SOIL SURFACE. USE AN ORGANIC MULCH IN THIS CASE (BUT NOT WOOD
FIBER), AND SEED THE AREA AS SOON AS POSSIBLE.
