BACKGROUND
Greenman -Pedersen Inc. (GPI) formerly LDS! Inc. in partnership with Grillot LLC. was contracted
by the Town of Leland to design and stabilize a section of Jackey's Creek along Highway 17 in
Leland, NC. The project includes approximately 200 feet of stream upstream of Highway 17. The
project is a part of the USDA-NRCS Emergency Watershed Protection Program for the restoration
of the project area to the pre -hurricane conditions.
Project
Site
Figure 1: Project Site Location Map
EXISTING CONDITIONS
Jackey's Creek lies within the coastal plain of North Carolina and its landscape is characterized
by agriculture, pineland, forested wetlands, and residential areas. Jackey's creek is a moderately
sizer coastal creek that first drains to the Brunswick River before entering the Cape Fear River
and the Atlantic Ocean. The project area starts upstream in a lowland forested area then passes
through utility easements and ends as the Creek passes under Highway 17. The soils present
within the project sites are primarily fine sandy and mucky soils that are typical of North Carolina's
Coastal Region. The damage done to the Project site was caused by approximately 29.5 inches
of rainfall that occurred during Hurricane Florence. This resulted in debris and sediment build
stream bank erosion, and significant scour around existing utilities (overhead utility pole and
guywires, subsurface utilities, and bridge abutments).

PROJECT GOALS
The purpose of this project is to provide design (GPI) and construction (Grillot, LLC.) services to
restore the project area to pre -Hurricane Florence conditions and stabilize the stream corridor
for to mitigate damages from future storm events. This will be achieved by the following project
objectives:
• Channel bank stabilization via grading and planting
• Installation of in -stream structures to maintain stable stream corridor
• Protection of existing utilized via stream stabilization

HYDROLOGY
Watershed characteristics for Jackey's Creek Watershed was determined primarily through the
USGS StreamStats tool along with field reconnaissance. The project site is within the Cape
Fear Watershed. It was found that the watershed draining into the stream is approximately 2.77
sq miles (120661 Acres) in size and has a 100-year peak flow of approximately 696 CFS Table

HYDRAULICS
The dimensional parameters for the proposed stream at Jackey's Creek were calculated by
referencing the work of Barbara Doll. Her work statistically analyzed the dimensional
characteristics of pristine streams within the coastal regions of North Carolina to determine the
parameters of stable, healthy stream.

PROPOSED DESIGN
The Project Design consist of approximately 230 linear feet of channel stabilization. This will
involve the instillation of instream log vanes and grade control riffle sections that will allow the
stream to hold grade during high -flow storm events. The banks of the channel will be graded
back at a stable slope and side slopes will be matted with fiber matting and staked with live
stakes to restore bank integrity. On banks that will experience a higher level of shear stress a
wood toe structure will be installed as an additional protection method. Please see attached

EROSION AND SEDIMENT CONTROL MEASURES
DURING PROJECT IMPLEMENTATION, BMPS/CONSERVATION MEASURES WILL BE IMPLEMENTED TO REDUCE
SEDIMENTATION INTO MCALPINE CREEK TRIB 1A EFFORTS WILL BE MADE TO LIMIT AND EXPEDITE EQUIPMENT TIME IN THE
STREAM CHANNEL. WHEN POSSIBLE, WORK WILL OCCUR FROM THE STREAMBANKS. THE DESIGN ATTEMPTS TO MINIMIZE
SEDIMENTATION AND OTHER POTENTIALLY NEGATIVE IMPACTS THROUGH THE FOLLOWING PRACTICES:
1. SUITABLE AND NON -SUITABLE SOILS SHALL BE PLACED IN DESIGNATED LOCATIONS SITE EROSION AND SEDIMENT
CONTROL.
2. THE CONTRACTOR WILL BE REQUIRED TO STAGE AND STORE EQUIPMENT AND MATERIALS AT LEAST 25 FEET FROM
TOPS OF BANKS.
3. EQUIPMENT WILL BE WELL -MAINTAINED, CLEANED PRIOR TO MOBILIZATION, AND CHECKED DAILY FOR LEAKS OF
PETROLEUM PRODUCTS.
4. FUELING WILL BE PERFORMED IN A CONTAINED AREA AWAY FROM SURFACE WATER.
5. THE CONTRACTOR WILL BE REQUIRED TO STAGE WORK SUCH THAT DISTURBED AREAS WILL BE STABILIZED IN PHASES
WITH SEEDING, MULCH AND BIODEGRADABLE (COIR) EROSION CONTROL MATTING (WHERE APPROPRIATE).
6. ALL TREES, UTILITIES AND OTHER SITE FEATURES WILL BE PROTECTED UNLESS MARKED FOR REMOVAL OR
RELOCATION.
7. ALL WORK ADJACENT TO STREAM WATERS WILL BE CONDUCTED IN A DRY WORK AREA TO THE EXTENT POSSIBLE.
8. TO THE EXTENT POSSIBLE, CONSTRUCTION WILL BE TIMED TO OCCUR DURING TIMES OF LOW FLOW.
9. CONSTRUCTION ACTIVITIES SHALL NOT OCCUR IN THE CHANNEL DURING WET WEATHER OR STORMFLOWS.
10. CONSTRUCTION SCHEDULING AND STAGING WILL BE TIMED TO MINIMIZE THE AMOUNT OF TIME SPENT WORKING IN
THE STREAM CHANNEL.
11. APPROPRIATELY SIZED EQUIPMENT WILL BE UTILIZED TO PREVENT EXCESSIVE COMPACTING AND MINIMIZE CLEARING.
SITE ACCESS AND STAGING
PRIMARY SITE ACCESS WILL OCCUR THROUGH THE DRIVEWAY ACCESS POINTS PER SITE EROSION AND SEDIMENT
CONTROL PLANS . ACCESS WITHIN THE PROJECT WILL UTILIZE A DESIGNATED ACCESS PATH FROM THE ACCESS
ESTABLISHED ON THE SIDE OF HIGHWAY 17.
PRIOR TO ANY SOIL DISTURBANCE AND HAULING, APPROXIMATELY EROSION AND SEDIMENT EROSION CONTROL DEVICES
SHALL BE INSTALLED ON THE SITE AS INDICATED IN THE CONSTRUCTION DOCUMENTS. SILT FENCE WILL BE LOCATED
ALONG THE DOWNSTREAM SIDE OF THE ACCESS AND STAGING AREAS. AT THE END OF THE PROJECT, WHEN ALL
DISTURBED AREAS HAVE BEEN STABILIZED, ALL EROSION AND SEDIMENT CONTROL DEVICES SHALL BE REMOVED.
MATERIAL SPECIFICATIONS, INSTALLATION PROCEDURES, AND MAINTENANCE SHALL CONFORM TO SECTION 6.62 OF THE
NORTH CAROLINA SEDIMENT CONTROL PLANNING AND DESIGN MANUAL.
STREAMBANK MATTING
700 GRAM COIR FIBER MATTING WILL BE USED ALONG NEWLY GRADED STREAM BANK SECTIONS. MATTING WILL NOT
CONTAIN SYNTHETIC (PLASTIC) MATERIALS. MATTING WILL BE INSTALLED BEGINNING AT THE TOE OF STREAMBANK TO
OUTER EDGE OF BANKFULL SHELF. A COMBINATION OF 12-INCH AND 24-INCH WOODEN STAKES WILL BE USED TO SECURE
THE MATTING IN PLACE.
DUST CONTROL
EXPOSED SOILS ON LEVEL SURFACES WILL BE KEPT MOIST DURING DRY CONDITIONS TO MINIMIZE THE POTENTIAL FOR
WIND EROSION AND DUST ACCUMULATION.
STORMWATER
THE STREAM RESTORATION PROJECT WILL NOT CREATE ADDITIONAL POINT SOURCES OF STORMWATER. THE INTENT OF
THE PROJECT IS TO IMPROVE OVERALL WATER QUALITY IN JACKEY'S CREEK BY STABILIZING ERODING STREAMBANKS,
PROVIDING FLOODPLAIN STORAGE, AND PROMOTING APPROPRIATE RIPARIAN VEGETATION.
ALL CONSTRUCTION ACTIVITIES WILL CONFORM TO NORTH CAROLINA GENERAL STORMWATER PERMIT NCG 010000.
SPECIFICALLY:
1. SOIL STABILIZATION SHALL BE ACHIEVED ON ANY AREA OF A SITE WHERE LAND -DISTURBING ACTIVITIES HAVE
TEMPORARILY OR PERMANENTLY CEASED, ALL PERIMETER SLOPES AND ALL SLOPES STEEPER THAN 3 HORIZONTAL

SEEDING TEMPORARY & PERMANENT
• AREAS TO BE SEEDED SHALL BE DRESSED TO A SMOOTH, FIRM SURFACE. ON SITES
WHERE EQUIPMENT CAN OPERATE ON SLOPES SAFELY, THE SEEDBED SHALL BE
ADEQUATELY LOOSENED (4 TO 6 INCHES DEEP) AND SMOOTHED. DEPENDING ON SOIL
AND MOISTURE CONDITIONS, DISKING OR CULTIPACKING, OR BOTH, MAY BE
NECESSARY TO PROPERLY PREPARE A SEEDBED. WHERE EQUIPMENT CANNOT
OPERATE SAFELY, THE SEEDBED SHALL BE PREPARED BY HAND METHODS BY
SCARIFYING TO PROVIDE A ROUGHENED SOIL SURFACE SO THAT BROADCAST SEED
WILL REMAIN IN PLACE.
• FERTILIZER, LIME, AND OTHER SOIL AMENDMENTS SHALL BE APPLIED AS SPECIFIED IN
SPECIFICATIONS. THE FERTILIZER AND SOIL AMENDMENTS SHALL BE THOROUGHLY
INCORPORATED INTO THE SOIL IMMEDIATELY FOLLOWING SURFACE APPLICATION.
• ALL DISTURBED AREAS SHALL BE SEEDED WHEN THEY ARE EXPECTED TO BE BARE OF
GROUND OVER FOR MORE THAN 15 CALENDAR DAYS; WHERE ACTIVE CONSTRUCTION
IS NOT BEING UNDERTAKEN, OR AS DIRECTED BY THE ENGINEER/INSPECTOR. THESE
AREAS SHALL BE SEEDED (TEMPORARY SEED MIX) AT THE END OF EACH DAY UNLESS
OTHERWISE DIRECTED BY THE ENGINEER/INSPECTOR.
• SEEDING (PERMANENT SEED MIX) SHALL BE ACCOMPLISHED WITHIN TWO (2) DAYS
AFTER FINAL GRADING IS COMPLETED AND APPROVED BY THE ENGINEER.
• FERTILIZER SHALL BE APPLIED AT THE RATE OF 1,000 LBS. PER ACRE. THE FERTILIZER
SHALL BE 10-10-10, OR EQUIVALENT. LIME SHALL BE APPLIED AT THE RATE OF TWO (2)
TONS PER ACRE. STRAW SHALL BE APPLIED AT A RATE OF TWO (2) TONS PER ACRE.
THE AREA SHOULD THEN BE SMOOTHED AND ANY DEBRIS LARGER THAN 3 INCHES IN
DIAMETER OR WHICH WOULD INTERFERE WITH MOWING SHALL BE REMOVED FROM THE
SURFACE. A CYCLONE SEEDER, DRILL OR CULTIPACKER SEEDER SHALL BE USED TO
APPLY THE SPECIFIED SEED EVENLY ON THE FRESHLY PREPARED SEEDBED. WHEN
SEED IS BROADCAST, A CULTIPACKER OR OTHER APPROPRIATE EQUIPMENT SHALL BE
USED IMMEDIATELY FOLLOWING SEEDING TO INCORPORATE THE SEED.
LIVE STAKES
• FOUR (4) WEEKS PRIOR TO INSTALLATION OF LIVE STAKES CONTRACTOR SHALL
SUBMIT A ROPOSED HARVESTING AND CONSTRUCTION SCHEDULE, INCLUDING SOURCE
OF SUPPLY OF LIVE CUTTING, TO PROJECT ENGINEER FOR REVIEW AND APPROVAL. NO
WORK SHALL BE PERFORMED UNTIL PROJECT ENGINEER APPROVES THE SOURCE AND
SCHEDULE. HARVESTING, TRANSPORTING, AND INSTALLATION SHALL TAKE PLACE
WHEN PLANTS ARE DORMANT (DECEMBER 1 THROUGH APRIL 1). IF DUE TO
CONSTRUCTION SCHEDULING LIVE STAKES CANNOT BE USED BASED ON THE
TIMEFRAMES SET ABOVE, LIVE TUBELINGS OF THE SAME SPECIES SHALL BE
SUBSTITUTED WITH APPROVAL FOR THE PROJECT ENGINEER.
• PLANT MATERIALS SHALL BE FROM SOURCES THAT ORIGINATED WITHIN PLANT
HARDINESS ZONES 7 OR 8. LIVE CUTTINGS FOR LIVE STAKES SHALL BE 0.75 INCHES TO
2.0 INCHES IN DIAMETER AND 3 FEET IN LENGTH. SIDE BRANCHES SHALL BE REMOVED
AND BARK LEFT INTACT PRIOR TO INSTALLATION. BUDS ON THE STAKES SHALL BE
ORIENTED IN AN UPWARD POSITION. CONTRACTOR SHALL SCRAPE A PORTION OF THE
CAMBIUM LAYER OFF EACH LIVE STAKE AT THE BASAL END APPROXIMATELY TWO (2)
INCHES IN LENGTH BY 0.25 INCHES WIDE TO STIMULATE ROOT GROWTH. THE BASAL
ENDS SHALL BE DIPPED IN A ROOT STIMULATING GROWTH HORMONE APPROVED BY
THE PROJECT ENGINEER. THE BASAL ENDS SHALL BE TAPERED TO A POINT FOR EASY
INSERTION INTO THE SOIL. THE TOP SHALL BE CUT SMOOTH AND SQUARE.
• THE TOPS OF THE LIVE STAKES SHALL BE PAINTED WITH LATEX TREE MARKING PAINT
TO ENSURE CORRECT PLANTING DIRECTION. MARK SPECIES WITH DIFFERENT COLORS.
LIVE STAKE CUTTINGS SHALL CONSIST OF THE SPECIES AS LISTED ON THE
CONSTRUCTION DRAWINGS.
• LIVE STAKE INSTALLATION - DRIVE LIVE STAKES INTO THE GROUND SO THAT
SEVENTY-FIVE PERCENT (75%) OF THE STAKE IS BELOW THE GROUND SURFACE. FOR
EASY INSERTION INTO THE SOIL THE BOTTOM END OF THE STAKE SHOULD BE CUT AT
AN ANGLE OF 30 TO 45 DEGREES. TO ENSURE A FLAT SURFACE FOR HAMMERING INTO
THE SLOPE, THE TOP SHOULD BE CUT AT 90-DEGREE ANGLE. FOR LARGER BRANCHES
THE USE OF PRUNING SHEARS OR POWER SAW MAY BE NECESSARY. ALL BUDS OF THE
LIVE BRANCH SHOULD BE FACED UPWARDS DURING STAKING. AS SHOWN IN THE
DETAILED PLAN ABOVE. THE CONTRACTOR SHALL USE A DEADPAN HAMMER FOR
DRIVING THE STAKE DIRECTLY INTO THE GROUND OR DRIVE A PILOT HOLE, SMALLER IN
DIAMETER THEN THE LIVE STAKE, AND THEN DRIVING THE LIVE STAKE INTO THE PILOT
HOLE.
• CONTRACTOR SHALL STAGGER SPECIES AS DIRECTED BY PROJECT ENGINEER.
• THE PROJECT ENGINEER SHALL MAKE A FINAL INSPECTION WITH THE CONTRACTOR TO
ENSURE ALL LIVE STAKES HAVE BEEN INSTALLED ACCORDING TO THE SPECIFICATION,
PLANS, AND DETAILS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR CORRECTING
ALL DEFICIENCIES WITHIN TEN (10) CALENDAR DAYS OF THE INSPECTION. THE
PROJECT ENGINEER AND CONTRACTOR PRIOR TO FINAL COMPLETION SHALL PERFORM
A FINAL INSPECTION OF THE CORRECTED ACTIONS.
TREE SEEDLINGS
• HARVESTING, TRANSPORTING, AND INSTALLATION SHALL TAKE PLACE WHEN PLANTS
ARE DORMANT (DECEMBER 1 THROUGH APRIL 1); UNLESS OTHERWISE DIRECTED BY
PROJECT ENGINEER.
• CONTRACTOR SHALL SUBMIT TO PROJECT ENGINEER FIVE (5) LIVE SEEDLINGS OF EACH
SPECIES ABOVE, FOUR (4) WEEKS PRIOR TO PLANTING FOR APPROVAL. CONTRACTOR
SHALL NOT PLANT ANY SEEDLINGS UNTIL PROJECT ENGINEER APPROVES OF
SUBMITTED SEEDLING STOCK. SUBMITTAL SHALL BE MADE IN AN APPROVED NURSERY
TREE BAG ALONG WITH SEEDLING AND NURSERY INFORMATION. SEEDLINGS SHALL BE
CLEARLY MARKED FOR IDENTIFICATION PURPOSES.
• NO MATERIAL SHALL BE PLANTED WHEN THE GROUND OR BACKFILL IS IN A FROZEN
CONDITION, OR CONDITIONS ARE UNUSUALLY WET, AS DETERMINED BY THE PROJECT
ENGINEER.TREE SEEDLINGS SHALL BE ONE (1) GALLON NURSERY STOCK.
• 2. PLANTS OF THE SAME SPECIES SHOULD BE PLANTED IN CLUSTERS, THESE CLUSTERS
SHOULD CONTAIN (5) FIVE PLANTS OF THAT SPECIES. NO MORE THAN ONE (1) CLUSTER OR
FIVE (5) PLUGS OF THE SAME SPECIES WITHIN A 10 FT BY 10 FT GRID. YIELDING 302 OR 600
SEEDLINGS PER ACRE DEPENDING ON ZONE. SEEDLINGS SHALL BE PLANTED IN ZONES
IN ACCORDANCE WITH CONSTRUCTION DRAWINGS.
• SEEDLINGS SHALL BE PLANTED IN A HOLE MADE WITH A TREE PLANTING BAR, DIBBLE,
MATTOCK, OR OTHER APPROPRIATE TOOL. THE HOLE SHALL BE LARGE ENOUGH TO
ACCOMMODATE THE ENTIRE ROOT SYSTEM. EACH SEEDLING SHALL BE PLANTED AT
THE SAME DEPTH AS IT GREW IN THE NURSERY. EACH SEEDLING SHALL BE GIVEN A
LIGHT TUG TO ENSURE PROPER PLANTING. ANY SEEDLING NOT SNUG MUST BE RESET.
SEEDLINGS SHALL BE KEPT MOIST UNTIL PLANTED. SEEDLINGS THAT ARE TO BE
