PRE -CONSTRUCTION CONFERENCE, ONE WEEK PRIOR TO THE COMMENCEMENT OF LAND
DISTURBING ACTIVITY, AND ONE WEEK PRIOR TO THE FINAL INSPECTION.
ES-3: ALL EROSION AND SEDIMENT CONTROL MEASURES ARE TO BE PLACED PRIOR TO
OR AS THE FIRST STEP IN CLEARING.
ES-4: A COPY OF THE APPROVED EROSION AND SEDIMENT CONTROL PLAN SHALL BE
MAINTAINED ON THE SITE AT ALL TIMES.
ES-5: PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES IN AREAS OTHER THAN
INDICATED ON THESE PLANS (INCLUDING, BUT NOT LIMITED TO, OFF -SITE BORROW OR
WASTE AREAS), THE CONTRACTOR SHALL SUBMIT A SUPPLEMENTARY EROSION CONTROL
PLAN TO THE OWNER FOR REVIEW AND APPROVAL BY THE PLAN APPROVING AUTHORITY.
ES-6: THE CONTRACTOR IS RESPONSIBLE FOR INSTALLATION OF ADDITIONAL EROSION
CONTROL MEASURES NECESSARY TO PREVENT EROSION AND SEDIMENTATION SUCH AS
PROTECTION OF TEMPORARY EARTH STOCKPILES AS DETERMINED BY THE PLAN
APPROVING AUTHORITY.

14. ALL APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS PERTAINING TO
WORKING IN OR CROSSING LIVE WATERCOURSES SHALL BE MET.
15. THE BED AND BANKS OF A WATERCOURSE SHALL BE STABILIZED IMMEDIATELY
AFTER WORK IN THE WATERCOURSE IS COMPLETED.
16. UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE

WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER.
18. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED
WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY
MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL
PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS

PROJECT DESCRIPTION
THIS SITE IS
BEING
SUBSTATION.
THE
AREA OF DISTURBANCE WILL
BE APPROXIMATELY 3.89
ACRES.
EXISTING SITE CONDITIONS
CURRENTLY THE SITE IS COVERED WITH GRASS, EXISTING SUBSTATION STONE YARD AND
GRAVEL ROADS. HIGH VOLTAGE ELECTRICAL LINES TRAVERSE THE SITE. THE SITE IS VERY
FLAT AND DRAINS IN TWO DIRECTIONS AS SHOWN ON SHEET 3. THE FRONT OF THE SITE
DRAINS INTO THE ROADSIDE DITCH WHERE FLOW IS SPLIT WITH SOME EXITING THE PROPERTY
TO THE NORTH AND SOME HEADING SOUTH. DRAINAGE FROM THE BACK OF THE SITE EXITS
THE PROPERTY IN A DRAINAGE DITCH WHICH FLOWS PARALLEL TO A RAILROAD TRACK.
THERE IS A WETLAND AREA ON EAST SIDE OF THE SITE WHICH WILL NOT BE AFFECTED BY
THIS PROJECT.
ADJACENT AREAS
THE SITE IS SURROUNDED BY RESIDENTIAL PROPERTIES WITH GRASS AND WOODS TO THE
NORTH AND SOUTH, STATE ROUTE 1218 TO THE WEST AND NORFOLK AND SOUTHERN
RAILWAY TO THE EAST.
OFF -SITE AREAS
THERE ARE NO OFF -SITE ACTIVITIES ANTICIPATED IN ASSOCIATION WITH THIS PROJECT.
SOILS
SOILS IN THE PROJECT AREA ARE LISTED IN THE NRCS WEB SOIL SURVEY FOR PERQUIMANS
COUNTY AS TOMOTLEY FINE SANDY LOAM (HYDROLOGIC SOIL GROUP "B/D"). TOMOTLEY HAS
A K FACTOR OF 0.20 (LOW ERODABILITY).
CRITICAL AREAS
NO CRITICAL AREAS HAVE BEEN IDENTIFIED ON THE SITE.
1. OWNER SHALL NOTIFY COUNTY 48 HOURS PRIOR TO THE START OF CONSTRUCTION IN
ORDER TO SCHEDULE AN ON -SITE PRE -CONSTRUCTION MEETING. THE CONTRACTOR'S
CERTIFIED RESPONSIBLE LAND DISTURBER (CRLD) MUST ATTEND THE PRE -CONSTRUCTION
MEETING.
2. INSTALL CONSTRUCTION ENTRANCE © 6.06 AS DESIGNATED ON THE PLANS.
3. INSTALL SIL FENCE SF 6.62 ALONG DOWNSLOPE PERIMETERS AND STRAW BALES
BARRIERS CD 6.83 ACROSS DRAINWAYS AS SHOWN ON THE PLANS.
4. PROCEED WITH GRADING AND OTHER SITE WORK AS SHOWN ON SHEET 2.
5. FINE GRADE, MULCH, SEED AND STABILIZE WITH GRASS OR APPLY GRAVEL TO ALL
DISTURBED AREAS AS SOON ASSIBLE. CONTRACTOR SHALL INSTALL DEGRADABLE
SOIL STABILIZATION BLANKETS IN ACCORDANCE WITH STANDARD &SPEC. 3.36 OF
THE NORTH CAROLINA EROSION A SEDIMENT CONTROL PLANNING AND DESIGN MANUAL
AND THE MANUFACTURER'S INSTRUCTIONS. BLANKETS B/ INSTALLED IN DRAINAGE
CHANNELS SHALL BE NORTH AMERICAN GREEN SC150 D BLE NET BLANKET, 70% STRAW,
30% COCONUT WITH PERMISSIBLE SHEAR STRESS OF 2.0 LBS./S.F. AND MAX. VELOCITY
OF 8 F.P.S., OR APPROVED EQUAL.
6. AFTER STABILIZATION OF THE ENTIRE SITE HAS BEEN ACHIEVED, ALL TEMPORARY E&S
MEASURES SHALL BE REMOVED.
MAINTENANCE
CONTRACTOR IS RESPONSIBLE FOR REGULAR INSPECTION AND MAINTENANCE OF ALL
EROSION AND SEDIMENT CONTROL DEVICES. IN GENERAL, ALL EROSION AND SEDIMENT
CONTROLS SHALL SHALL BE INSPECTED ON A DAILY BASIS AND AFTER EACH
SIGNIFICANT RAINFALL. THE FOLLOWING ITEMS WILL BE CHECKED IN PARTICULAR:
1. SILT FENCE AND STRAW BALE BARRIERS SHALL BE CHECKED FOR UNDERMINING,
"END RUNS" AND FABRIC INTEGRITY. REMOVE SEDIMENT WHEN THE LEVEL OF
DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER.
2. CHECK SEEDED AREAS TO ENSURE THAT A GOOD STAND IS MAINTAINED. RESEED
AND FERTILIZE AS NEEDED.

F. COMPACTION: IMMEDIATLEY AFTER SEEDING IS COMPLETED, THE SEEDBED SHALL BE COMPACTED BY MEANS
OF AN APPRROVED LAWN ROLLER WEIGHING 40 TO 65 POUNDS PER FOOT OF WIDTH FOR CLAY SOIL AND 150 TO
200 POUNDS PER FOOT OF WIDTH FOR SANDY OR LIGHT SOIL, UNLESS AN INTERVENING PRECIPITATION CAUSES
SUCH AS ROLLING TO BE DETRIMENTAL TO THE SEEDED AREA.
G.OVERSEEDING: AREAS INDICATED TO BE OVERSEEDED SHALL FOLLOW ALL SPECIFIC PROCEDURES AND
METHODS FOR SEEDING EXCLUDING THE INCORPORATION OF ADDITIONAL TOPSOIL. PROVIDE A SMOOTH FINISH
GRADE TRANSITION BETWEEN SEEDED AREAS AND OVERSEEDED AREAS..
9. APPLICATION RATE - PERMANENT SEEDING
A. APPLICATION OF LIME, FERTILIZER, AND SEED:
1. LIME WITH 40 LBS. PER 1,000 SQ. FT. BEFORE SEEDING.
2. FERTILIZE WITH 15 LBS. PER 1,000 SQ. FT. WHEN SEEDING, TOP DRESS WITH 10 LBS. PER 1,000 SQ. FT. WHEN
COVER IS ESTABLISHED.
3. PROVIDE PERMANENT SEEDING TO COMPLETED AREAS DURING THE PERMANENT SEEDING PERIOD. IF GRADING
IS COMPLETED AT TIMES OTHER THAN THE RECOMMENDED SEASON, PROVIDE TEMPORARY SEEDING OR OTHER
PROTECTION APPROVED BY THE ENGINEER UNTIL THE APPROPRIATE PLANTING SEASON BEGINS.
10. APPLICATION RATE -TEMPORARY SEEDING
A. APPLICATION OF FERTILIZER AND SEED:
1. FERTILIZE WITH 15 LBS. PER 1,000 SQ. FT. WHEN SEEDING. TOP DRESS WITH 10 LBS. PER 1,000 SQ. FT. WHEN
COVER IS ESTABLISHED.
2. BETWEEN FEBRUARY AND MAY AND SEPTEMBER AND NOVEMBER, SEED WITH 13D LBS. PER ACRE OF RYE;
BETWEEN JUNE AND AUGUST SEED WITH 40 LBS. PER ACRE OF BROW NTOP MILLET.
11. APPLICATION RATE -MULCH
A. APPLY MULCH AT THE RATE OF 100 LBS. PER 1,000 SQ. FT. ANCHOR MULCH IN PLACE.
12. WATERING: APPLY WATER WITH A FINE SPRAY IMMEDIATELY AFTER EACH AREA HAS BEEN MULCHED. SATURATE
TO 4 INCHES OF SOIL.
13. MAINTENANCE:
A. PROTECT AND CARE FOR SEEDED AREAS UNTIL GRASS IS A WELL ESTABLISHED, UNIFORM GROWTH AT LEAST 4
INCHES HIGH.
B. WATER TO PREVENT GRASS AND SOIL FROM DRYING OUT.
C. ONCE ESTABLISHED, REMOVE EXCESS MULCH AND MOW GRASS TO A HEIGHT NOT LESS THAN 1-1/2 INCHES OR
GREATER THAN 2-112 INCHES.
D. CONTROL GROWTH OF WEEDS. -
E. MAINTAIN GRASS FOR TWO WEEKS AFTER INITIAL MOWING.
F. RESEED AREAS THAT DO NOT SHOW A PROMPT CATCH AT INTERVALS OF 21 DAYS UNTIL A UNIFORM GROWTH IS
ESTABLISHED.
G. RESEED AREAS DAMAGED DUE TO ACTS OF NEGLECT BY RESIDENTS OR VANDALISM ONLY AT THE REQUEST
AND EXPENSE OF OWNER.
14. MAINTENANCE PERIOD:
A. THE CONTRACTOR SHALL BE RESPONSIBLE FOR THE PROPER CARE AND MAINTENANCE OF THE SEEDED AREAS
UNTIL THE WORK UNDER THE ENTIRE CONTRACT HAS REACHED FINAL COMPLETION AND HAS BEEN ACCEPTED BY
THE OWNER.
B. MAINTENANCE SHALL CONSIST OF REPAIR AND REPLACEMENT OF ERODED AREAS, WATERING, WEED AND PEST
CONTROL, REMOVAL OF UNWANTED GRASS GROWTH, RE -FERTILIZING, RE -LIMING, RESEEDING, AND RE -MULCHING
AS NECESSARY TO PROVIDE AN EVEN, FIXED GROWTH OF GRASS.
15. CONTRACTOR SHALL PROVIDE AGAINST TRAFFIC, AND SHALL ERECT NECESSARY BARRICADES AND WARNING
SIGNS IMMEDIATELY AFTER PLANTING IS COMPLETED.
16. WATERING: KEEP SEEDED AREAS CONSTANTLY MOIST FOR A PERIOD OF 3 WEEKS, USING FREQUENT LIGHT
WATERING (2 TO 4 TIMES PER DAY) RATHER THAN SOAKING THE SOIL WHEN IT BECOMES DRY. THE AMOUNT AND
FREQUENCY OF WATER APPLICATION WILL VARY WITH SOIL TEXTURE. AFTER 3 WEEKS, WATER EACH AREA AT
LEAST ONCE A DAY UNTIL THE GRASS HAS ACHIEVED COMPLETE COVER.
17. PLANTING FERTILIZATION: THREE WEEKS AFTER PLANTING AND AGAIN SIX WEEKS AFTER PLANTING, FERTILIZE
SEEDED AREAS WITH 500 POUNDS PER ACRE OF 10-10-10 FERTILIZER.TO AVOID BURNING, FERTILIZE WHEN GRASS
IS DRYAND WATER IMMEDIATELY FOLLOWING APPLICATION.
18. MOWING: THE SEEDED AREAS SHALL BE MOWED WITH APPROVED MOWING EQUIPMENT TO A HEIGHT OF 2 AND 1/2
INCHES WHENEVER THE AVERAGE HEIGHT OF THE GRASS BECOMES 4 INCHES. IF WEEDS OR OTHER UNDESIRABLE
VEGETATION THREATEN TO SMOTHER THE PLANTED SPECIES, SUCH VEGETATION SHALL BE MOWED, OR IN THE
CASE OF RANK GROWTHS, SHALL BE UPROOTED AND REMOVED FROM THE AREA.
19. REPAIR:
1. WHEN THE SURFACE OF ANY PART OF AN AREA WHICH HAS BEEN SEEDED IS GULLIED OR OTHERWISE DAMAGED,
THE AFFECTED PORTIONS SHALL BE REPAIRED TO RE-ESTABLISH THE CONDITION AND GRADE OF SEED PRIOR TO
THE INJURY AND THEN SHALLB E RESEEDED AS HEREIN SPECIFIED AT NO ADDITIONAL EXPENSE TO THE OWNER.
2. ANY BARE AREAS GREATER THAN 2 SQUARE FEET OR AREAS OF INSUFFICIENT COVERAGE SHALL BE REWORKED
AND RESEEDED DURING THE MAINTENANCE PERIOD.
HERBACEOUS PLANTS -Seeding recommendations for primary stabilization
