THE PURPOSE OF THE EROSION CONTROL MEASURES SHOWN ON THESE PLANS SHALL BE TO PRECLUDE
THE TRANSPORT OF ALL WATERBORNE SEDIMENTS RESULTING FROM CONSTRUCTION ACTIVITIES FROM
ENTERING ONTO ADJACENT PROPERTIES OR STATE WATERS. IF FIELD INSPECTION REVEALS THE
INADEQUACY OF THE PLAN TO CONFINE SEDIMENT TO THE PROJECT SITE, ALL APPROPRIATE MODIFICATIONS
WILL BE MADE TO CORRECT ANY PLAN DEFICIENCIES. IN ADDITION TO THESE NOTES, ALL PROVISIONS OF
THE NORTH CAROLINA EROSION AND SEDIMENT CONTROL REGULATIONS SHALL APPLY TO THIS PROJECT.
1. ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE INSTALLED AND MAINTAINED IN
ACCORDANCE WITH STATE APPROVED PLANS AND THETHE NORTH CAROLINA EROSION AND SEDIMENT
PLANNING AND DESIGN MANUAL, 2003. THE CONTRACTOR SHALL BE THOROUGHLY FAMILIAR WITH ALL
APPUCABLE MEASURES CONTAINED THEREIN THAT MAY BE PERTINENT TO THIS PROJECT, INCLUDING
MINIMUM STANDARDS 1 THROUGH 19. IF THE APPROVED EROSION AND SEDIMENT CONTROL PLAN IS
FOUND TO BE INADEQUATE IN THE FIELD, THE MINIMUM STANDARDS WILL APPLY IN ADDITION TO THE
PROVISIONS OF THE APPROVED PLAN.
2. A PRECONSTRUCTION MEETING SHALL BE HELD ON SITE BETWEEN THE CITY, THE COUNTY, THE STATE,
THE DEVELOPER, THE PROJECT ENGINEER, AND THE CONTRACTOR PRIOR TO START OF CONSTRUCTION.
THE CONTRACTOR SHALL SUBMIT A SEQUENCE OF CONSTRUCTION TO THE COUNTY FOR APPROVAL PRIOR
TO THE PRECONSTRUCTION MEETING.
3. ALL POINTS OF CONSTRUCTION INGRESS AND EGRESS SHALL BE PROTECTED BY A TEMPORARY GRAVEL
CONSTRUCTION ENTRANCE (PRACTICE 6,06) TO PREVENT TRACKING OF MUD ONTO PUBLIC RIGHT-OF-WAYS.
DURING WET WEATHER IT MAY BE NECESSARY TO WASH VEHICLES TIRES AT THIS LOCATION. THE
ENTRANCE WILL BE GRADED SO THAT RUNOFF WATER WILL BE DIRECTED TO AN INLET STRUCTUREAND
AWAY FROM ADJACENT PROPERTY. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE
ROAD SHALL BE THOROUGHLY CLEANED AT THE END OF EACH DAY.
4. BMPS AND OTHER MEASURES INTENDED TO TRAP SEDIMENT ON -SITE MUST BE CONSTRUCTED AS A
FIRST STEP IN GRADING AND MUST BE MADE FUNCTIONAL PRIOR TO ANY UPSLOPE LAND DISTURBANCE
TAKING PLACE. EARTHEN STRUCTURES SUCH AS DIVERSIONS MUST BE SEEDED AND MULCHED
IMMEDIATELY AFTER INSTALLATION. PERIODIC INSPECTIONS OF THE EROSION CONTROL MEASURES BY THE
OWNER OR OWNERS REPRESENTATIVES SHALL BE MADE TO ASSESS THEIR CONDITION. ANY NECESSARY
MAINTENANCE OF THE MEASURES SHALL BE ACCOMPLISHED IMMEDIATELY AND SHALL INCLUDE THE REPAIR
OF MEASURES DAMAGED BY ANY SUBCONTRACTOR INCLUDING THOSE OF THE PUBLIC UTILITY COMPANIES.
5. SEDIMENT CONTROL MEASURES MAY REQUIRE MINOR FIELD ADJUSTMENTS AT TIME OF CONSTRUCTION
TO INSURE THEIR INTENDED PURPOSE IS ACCOMPLISHED. STATE APPROVAL WILL BE REQUIRED FOR
OTHER DEVIATIONS FROM THE APPROVED PLAN.
6, THE CONTRACTOR SHALL PLACE SOIL STOCKPILES AT THE LOCATIONS SHOWN ON THE PLAN. SOIL
STOCKPILES SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES,
7. THE CONTRACTOR SHALL COMPLETE DRAINAGE FACIUTIES WITHIN 30 DAYS FOLLOWING COMPLETION OF
BMP AT ANY POINT WITHIN THE PROJECT. THE INSTALLATION OF DRAINAGE FACILITIES SHALL TAKE
PRECEDENCE OVER ALL UNDERGROUND UTILITIES. OUTFALL DITCHES FROM DRAINAGE STRUCTURES SHALL
BE STABILIZED IMMEDIATELY AFTER CONSTRUCTION OF THE SAME. ANY DRAINAGE OUTFALLS REQUIRED FOR
A STREET MUST BE COMPLETED BEFORE STREET GRADING OR UTILITY INSTALLATION BEGINS,
B. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN
DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION
SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL
REMAIN DORMANT FOR LONGER THAT 30 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS
THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR.
9. THE TERM SEEDING FINAL VEGETATIVE COVER OR STABILIZATION ON THIS PLAN SHALL MEAN THE
SUCCESSFUL GERMINATION AND ESTA13USHMENT OF A STABLE GRASS COVER FROM A PROPERLY PREPARED
SEEDBED CONTAINING THE SPECIFIED AMOUNTS OF SEED, LIME AND FERTILIZER (PRACTICE 6.10 & 6.11).
IRRIGATION SHALL BE REQUIRED AS NECESSARY TO ENSURE ESTABLISHMENT OF GRASS COVER.
10. ALL SLOPES STEEPER THAN 3H:1V SHALL REQUIRE THE USE OF EROSION CONTROL BLANKET'S AND
MATTINGS TO AID IN THE ESTABLISHMENT OF A VEGETATIVE COVER. INSTALLATION SHALL BE IN
ACCORDANCE WITH PRACTICE 6.14, MULCHING, PRACTICE 6.14, SOIL STABILIZATION BLANKETS AND MATTING
AND MANUFACTURERS INSTRUCTIONS. NO SLOPES SHALL BE CREATED STEEPER THAN 2H:1V.
11. INLET PROTECTION (PRACTICE 6.51) SHALL BE PROVIDED FOR ALL STORM DRAIN AND CULVERT
INLETS FOLLOWING CONSTRUCTION OF THE SAME.
12. TEMPORARY EROSION CONTROL MEASURES SUCH AS SILT FENCE ARE NOT TO BE REMOVED UNTIL
ALL DISTURBED AREAS ARE STABILIZED. TRAPPED SEDIMENT SHALL BE SPREAD, SEEDED AND MULCHED.
AFTER THE PROJECT AND STABILIZATION IS COMPLETE, ALL EROSION AND SEDIMENT CONTROL MEASURES
SHALL BE REMOVED WITHIN 30 DAYS.
13. NO SEDIMENT TRAP OR SEDIMENT BASIN SHALL BE REMOVED UNTIL ALL DISTURBED AREAS ARE
STABILIZED.
14. RECORD QRAWINGS (AS-BUILTS) AND CONSTRUCTION CERTIFICATIONS ARE BOTH REQUIRED FOR
NEWLY CONSTRUCTED OR MODIFIED STORMWATER MANAGEMENT/BMP FACILITIES. CERTIFICATION ACTIVITIES
SHALL BE ADEQUATELY COORDINATED AND PERFORMED BEFORE, DURING AND FOLLOWING CONSTRUCTION IN
ACCORDANCE VITH THE CURRENT STATE REQIUREMENTS AND THE ELIZABETH CITY UNIFIED DEVELOPMENT
ORDINANCE, STORMWATER MANAGEMENT/BMP FACILITIES, RECORD DRAWING AND CONSTRUCTION

SIDE OF HALSTEAD ROAD IN ELIZABETH CITY, NORTH CAROLINA APPROXIMATELY 5000 FEET EAST OF
ROUTE 17 AND BYPASS. THE PROJECT ENCOMPASSES 149.4 ACRES OF LAND AND PROPOSES SINGLE
FAMILY RESIDENTIAL BUILDING LOTS. NINETY ONE LOTS WILL BE ESTATE LOTS, 15,000 SF OR MORE
LOCATED IN THE REAR OF THE SUBDIVISION. THE REST OF THE LOTS WILL BE DEVELOPED IN A CLUSTER
DEVELOPMENT, NINETY SIX LOTS WILL BE 10,000 SF REAR LOADED LOTS VIA AN ALLEY WAY AND 105
LOTS WILL 10,000 SF LOTS THAT ARE FRONT LOADED. THE SUBDIVISION WILL HAVE TWO TOT LOTS, ONE
COMMUNITY CENTER AND OPEN SPACE THAT WILL UTILIZED AS PARK SPACE. THE SUBDIVISION WILL HAVE
SIDEWALKS, CURB AND GUTTER ROAD WAY SYSTEM, PUBLIC AND PRIVATE UTILITY IMPROVEMENTS, AND A
COMPREHENSIVE STORMWATER MANAGEMENT SYSTEM. THE PROJECT SITE IS ZONED R-15 AND IS
IDENTIFIED AS TAX MAP & PARCEL ID #P65-1 7993765749 & #P88-9 8904108204,
DESCRIPTION OF SITE
THE PROPERTY IS PART OF A LARGER TRACT OF FARM LAND THAT WAS SUBDIVIDED. UNDER
PREDEVELOPMENT CONDITIONS, THE SITE IS USED AS FARMS FIELDS WITH DRAINAGE DITCHES. THE SITE IS
FLAT AND CLEARED. THE SITE IS BOUNDED BY DRAINAGE DITCHES ON THE NORTHERN, EASTERN, AND
SOUTHERN PROPERTY LINES, THE WESTERN BOUNDARY LINE IS BOUNDED BY A PROPOSED IN ROAD FROM
HALSTEAD ROAD AND A FARM FIELD. UNDER EXISTING CONDITIONS ALL RUNOFF FROM THE SITE DRAINS
VIA FARM DITCHES THAT HEAD TOWARD THE SOUTH OF THE PROPERTY. THE RUNOFF EXITS THE SITE VIA
A CULVERT UNDER HALSTEAD ROAD TOWARDS KNOBB CREEK, WHICH ULTIMATELY LEADS TO THE
PASQUOTANK RIVER.
ACENT ARE
CONSTRUCTION ACTIVITIES THAT WILL AFFECT ADJACENT AREAS TO THE PROJECT WILL INCLUDE
INSTALLATION OF A GRAVITY SEWER LINE TOWARDS A PUMP STATION UNDER DESIGN BY OTHERS. THE
PUMP STATION WILL BE LOCATED ON THE PROPERTY ADJACENT TO THE SUBDIVISION, LOCATED MIDWAY
UP THE WESTERN PROPERTY LINE OF THE SUBDIVISION.

THE SOILS ON THE SITE ARE CLASSIFIED AS CAPE FEAR SILT LOAM, 0% TO 2% SLOPES AND CAPE FEAR
MUCKY SILT LOAM, 0% TO 2% SLOPES.
THERE ARE NO CRITICAL AREAS OR EXCESSIVELY STEEP SLOPES THAT WILL BE DISTURBED BY THE
PROJECT CONSTRUCTION.
EROSION AND SEDIMENT CONTROL MEASURES
THE METHODS USED DURING CONSTRUCTION TO CONTROL EROSION AND SEDIMENTATION AREA DEPICTED
AND DETAILED ON THE PLANS. THE CONTROL MEASURES INCORPORATED INCLUDE CONSTRUCTION
ENTRANCE, SILT FENCE, INLET PROTECTION, BMPS, SEDIMENT BASINS AND OTHER METHODS IN
ACCORDANCE WITH THE NORTH CAROLINA EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN
MANUAL, 2003.
ALL DISTURBED AREAS NOT SCHEDULED FOR PAVING OR OTHER IMPERVIOUS COVER SHALL BE STABILIZED
WITH PERMANENT SEEDING AND/DR LANDSCAPING IMMEDIATELY FOLLOWING FINISH GRADING.
STORMWATER MANAGEMENT
THE PROPOSED STORMWATER MANAGEMENT PLAN FOR THIS PROJECT WILL INCLUDE THE USE OF FIVE
ONSITE WET DETENTION BASINS TO PROVIDE A STORMWATER MANAGEMENT SYSTEM TO ATTENUATE THE
INCREASED RUNOFF ANTICIPATED
NTI FROM SITE DEVELOPMENT AND AL
SO LSO TO MITIGATE THE INCREASED
POLLUTANT LOADING ASSOCIATED WITH THE INCREASED IMPERVIOUS COVER. BMP "A" WILL BE UTILIZED TO
ATTENUATE THE INCREASE RUNOFF AND BMP "B" THROUGH -E" WILL BE UTILIZED TO MITIGATE THE
INCREASE POLLUTANT LOADING. BMP "B" THROUGH "E" ARE DESIGNED TO REMOVE 90% OF THE TOTAL
SUSPENDED SOLIDS.
THE STORMWATER MANAGEMENT SYSTEM IS DESIGNED TO CONTROL THE 2-YEAR, 10-YEAR, 25-YEAR AND
50-YEAR TWENTY-FOUR HOUR, SCS TYPE II STORM EVENT, CONSIDERED INDIVIDUALLY, FOR POST
DEVELOPED CONDITIONS AT PREDEVELOPMENT RATES.
