PERMANENT SEEDING
GROUND COVER — Whenever land disturbing activity is undertaken on a
tract comprising more than one acre, if more than one continguous acre
is uncovered a ground cover sufficient to restrain erosion must be
planted or otherwise provided within 14 calendar days on that portion of
the tract upon further active construction is not being undertaken,
provided that this subsection shall not apply to cleared land forming the
basin of a reservoir to be inumdated.
GRADED SLOPES AND FILL — The angle for graded slopes and fills shall
be no greater that the angle which can be retained by the vegetative
cover or other adequate erosion control devices or structures. In any
event slopes greater than 3:1, shall be seeded within 7 calendar days
following any phase of grading; on other areas permanent ground cover
for all disturbed areas within 14 calendar days of completion of any
phase of grading, be planted or otherwise provided with ground cover,
devices, or structures sufficient to restrain erosion.
SEED BED PREPARATION — The seed bed shall be prepared by pulverizing
the soil in a manner to a depth of three inches for field conditions or
slopes that are 3:1 or flatter and/or to a depth of one inch to three
inches as determined on site for slopes steeper than 3:1. Tillage shall
continue until a well pulverized, firm, reasonably uniform seed bed is
prepared conforming substantially to ground elevations as shown on the
plans and/or as was exisitng prior to construction, blending uniformly
into adjacent topography. All stones, roots, sticks, rubbish, and other
objectionable material shall be removed.
The following material shall be used for reseeding disturbed areas: (note
that all rates are per 1000 sf)

MULCHING — After fertilizing, seeding, raking, and/or tilling, dried straw
shall be uniformly spread (approximately 1/4 of the ground should remain
visible to avoid smothering seedlings) over the area at the reate of 90
pounds per 1000 square feet. The straw shall be sprayed with liquid
asphalt to bond it together and anchor it in place, preventing it from
being scattered by wind and rain.
Liquid asphalt (thinned with kerosene) used during freezing weather shall
be either rapid or medium curing, applied at a rate of 200 gallons per ton
ad straw (approximately 9 gallons per 1000 square feet).
Emulsified (thinned with water) used when temperatures are less severe
shall be ropidcuring only, applied at a rate of 150 gallons per ton of straw
(approximately 7 gallons per 1000 square feet).
Jute matting or "Hold Gro" shall be used for temporary stabilization during
the establishment of permanent cover on problem areas such as future
grassed ditches, channels, ling slopes and steep banks.
MAINTEMANCE — The contractor shall maintain the seeded areas until
there is a uniform growth three inched high. Maintenance shall consisit of
watering, weed and pest control (within established lawns), fertilization,
erosion repair, reseeding and all else necessary to establish a vigorous
healthy and uniform stand of grass. All areas and spots which do not
show a uniform stand of grass for any reason shall be trated repeatedly
until a uniform stand is attained.

2 Place the gravel to the specific grade and dimensions shown on
the plans and smooth it.
3 Provide drainage to carry water to a sediment trap or other
suitable outlet.
4 Use geotextile fabrics because they improve stability of the
foundation in locations subject to seepage or high water table.
MAINTENANCE: 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.

FILTER FABRIC
Construction Specifications:
Materials —
1. Use a synthetic filter fabric of at least 95% by weight of polyolefins or polyester,
which is certified by the manufacturer or supplier as conforming to the requirements
in ASTM D 6461, which is shown in part in Table 6.62b.
Synthetic fabric should contain ultraviolet ray inhibitors and stabilizers to provide a
minimum of 6 months of expected usable construction life at a temperature range
of0to120F.
2. Ensure that posts for sediment fences are 1.33 lb/linear ft. steel with a minimum
length of 5 feet. Make sure that steel posts have projections to facilitate fastening
the fabric.
3. For reinforcement of standard strength filter fabric use wire fence with a minimum
14 gauge and a maximum mesh spacing of 6 inches.
Construction —
Construct the sediment barrier of standard strength or extra strength synthetic filter
fabrics.
1. Ensure that the height of the sediment fence does not exceed 24 inches above
the ground surface. (Higher fences may impound volumes of water sufficient to
cause failure of the structure.)
2. Construct the filter fabric from a continuous roll cut to the length of the barrier
to avoid joints. When joints are necessary, securely fasten the filter cloth only at a
support post with 4 feet minimum overlap to the next post.
3. Support standard strength filter fabric by wire mesh fastened securely to the
upslope side of the posts. Extend the wire mesh support to the bottom of the
trench. Fasten the wire reinforcement, then fabric on the upslope side of the fence
post. Wire or plastic zip ties shall have minimum 50 pound tensile strength.
4. When a wire mesh support fence is used, space posts a maximum of 8 feet
apart. Support posts should be driven securely into the ground a minimum of 24
inches.
RE TIES
1ND
BACKFILL TRENCH
AND COMPACT THOROUGHLY
VATURAL GROUND
kIMIN. UP
5. Extra strength filter fabric with 6 feet post spacing does not require wire mesh
support fence. Securely fasten the filter fabric directly to the posts. Wire or plastic
zip ties should have a minimum 50 pound tensile strength.
6. Excavate a trench approximately 4 inches wide and 8 inches deep along the
proposed line of posts and upslope from the barrier (Figure 6.62a).
7. Place 12 inches of the fabric along the bottom and side of the trench.
8. Backfill the trench with soil placed over the filter fabric and compact. Thorough
compaction of the backfill is critical to silt fence performance.
9. Do not attach filter fabric to existing trees.
Maintenance —
Inspect sediement fences at least once a week and after each rainfall. Make any
required repairs immediately.
1. Should the fabric of a sediment fence collapse, tear, decompose or become
ineffective, replace it promptly.
2. 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.
3. 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.

CONSTRUCTION SPECIFICATIONS:
1. CLEAR, GRUB, AND STRIP THE AREA UNDER THE EMBANKMENT OF ALL VEGETATION AND ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS OF ORGANIC MATTER
AND STOCKPILE OR DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE DESIGNATED DISPOSAL AREA. PLACE TEMPORARY SEDIMENT CONTROL MEASURES BELOW
BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY VEGETATION, ORGANIC MATTER, AND OTHER OBJECTIONABLE MATERIAL. PLACE THE FILL IN LIFTS
NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THE SKIMMER OR
PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER. SKIMMER HORIZONTAL MOVEMENT IS TO BE LIMITED BY METAL STAKES OR 2x4's. INSTALL SKIMMER PER
MANUFACTURER'S RECOMMENDATIONS.
4. PLACE THE BARREL (TYPICALLY 4-INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCH AS SAND,
GRAVEL, OR CRUSHED STONE AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4-INCH LAYERS AND COMPACT IT UNDER AND AROUND
THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT EMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE PIPE FROM THE FIRM CONTACT WITH ITS FOUNDATION WHEN
COMPACTING UNDER THE PIPE HAUNCHES. PLACE A MINIMUM DEPTH OF 2 FEET OF COMPACTED BACKFILL OVER THE PIPE SPILLWAY BEFORE CROSSING IT WITH CONSTRUCTION
EQUIPMENT. IN NO CASE SHOULD THE PIPE CONDUIT BE INSTALLED BY CUTTING A TRENCH THROUGH THE DAM AFTER THE EMBANKMENT IS COMPLETE.
5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURERS INSTRUCTIONS, OR AS DESIGNED.
6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOINT AT THE INLET OF THE BARREL PIPE. ATTACH THE FLEXIBLE JOINT TO THE BARREL PIPE
AND POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE BASIN. THIS WILL BE
USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE.
7. EARTHEN SPILLWAYS -INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH, AND
ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF THE SPILLWAY. THE SPILLWAY SHOULD BE LINED WITH LAMINATED PLASTIC OR
IMPERMEABLE GEOTEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG ENOUGH TO COVER THE BOTTOM AND SIDES AND EXTEND ONTO THE TOP OF THE DAM FOR ANCHORING IN
A TRENCH. THE EDGES MAY BE SECURED WITH 8-INCH STAPLES OR PINS. THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO STABLE GROUND. THE
WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR SPLICED; OTHERWISE WATER CAN GET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC IS INSUFFICIENT FOR THE
ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS, SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTIONS) SHOULD OVERLAP THE LOWER SECTIONS) SO THAT
WATER CANNOT FLOW UNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS. (ADAPTED FROM "A MANUAL FOR DESIGNING,
INSTALLING AND MAINTAINING SKIMMER SEDIMENT BASINS." FEBRUARY, 1999. J. W. FAIRCLOTH & SON.).
8. INLETS - DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT
SEDIMENT -LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP EFFICIENCY.
9. EROSION CONTROL - CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE EMBANKMENT
BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY, AND SEED AND STABILIZE THE EMBANKMENT AND ALL OTHER DISTURBED AREAS ABOVE THE CREST OF THE
PRINCIPAL SPILLWAY IMMEDIATELY AFTER CONSTRUCTION (REFERENCES: SURFACE STABILIZATION).
10. INSTALL POROUS BAFFLES AS SPECIFIED IN PRACTICE 6.65, POROUS BAFFLES. INSTALL A MINIMUM THREE ROWS OF POROUS BAFFLES ACROSS WIDTH OF BASIN. BAFFLE MATERIAL
TO BE COIR EROSION BLANKET, COIR MESH OR SIMILAR.
11. AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE AND ALL THE SEDIMENT. SMOOTH THE AREA TO BLEND WITH THE
ADJOINING AREAS AND STABILIZE PROPERLY (REFERENCES: SURFACE STABILIZATION).
12. SAFETY - SEDIMENT BASINS MAY ATTRACT CHILDREN AND CAN BE DANGEROUS. AVOID STEEP SIDE SLOPES, AND FENCE AND MARK BASINS WITH WARNING SIGNS IF TRESPASSING
IS LIKELY. FOLLOW ALL STATE AND LOCAL REQUIREMENTS.
MAINTENANCE:
1. INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (ONE-HALF INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT
AND RESTORE THE BASIN TO ITS ORIGINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO ONE-HALF THE HEIGHT OF THE FIRST BAFFLE. PULL THE SKIMMER TO ONE SIDE SO THAT
THE SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUST AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE
VEGETATION GROWING IN THE BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.
2. REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR AROUND THEM.
3. IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE
DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE
SKIMMER TO SEE IF IT IS CLOGGED; IF SO REMOVE THE DEBRIS.
4. IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE
SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
5. CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. CHECK THE EMBANKMENT,
SPILLWAYS, AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRS IMMEDIATELY. REMOVE ALL TRASH
AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS.
6. FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM PLUGGING WITH
ICE.

CONSTRUCTION
SPECIFICATIONS: 1 Ensure that the subgrade for the filter and riprap follows =r
the required lines and grades as shown in the plan. Compact any -
fill required in the subgrade to the density of the surrounding
undisturbed material. Low areas in the subgrade on undisturbed
soil may also be filled by increasing the riprap thickness.
2 The riprap and gravel filter must conform to the specified
grading limits shown on the plans.
3 Filter cloth, when used, must meet design requirements and be
properly protected form punching or tearing during installation. Repair
any damage by removing the riprap and placing another piece of filter
cloth over the damaged area. All connecting joints should overlap a
minimum of 1 ft. If the damage is extensive, replace the entire
filter cloth.
4 Riprap may be placed by equipment, but take care to avoid damaging
the filter.
5 The minimum thickness of the riprap should be 1.5 times the
maximum stone diameter.
6 Riprap may be field stone or rough quarry stone. It should be
hard, angular, highly weather -resistant and well graded.
7 Construct the apron on zero grade with no overfall at the end. Make
the top of the riprap at the downstream end level with the receiving
area or slightly below it.
8 Ensure that the apron is properly aligned with the receiving stream
and preferably straight throughout its length. if a curve is needed to
fit site conditions, place it in the upper section of the apron.
9 Immediately after construction, stabilize all disturbed areas with vegetation.
MAINTENANCE: Inspect riprap outlet structures after heavey rains 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.

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing activity.
Temporary ground stabilization shall be maintained in a manner to render the surface stable
against accelerated erosion until permanent ground stabilization is achieved.
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilization

• Appropriately applied straw or other mulch
• Shrubs or other permanent plantings covered
• Plastic sheeting
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt
or retaining walls
• Rolled erosion control products with grass seed
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during construction,
selecting from the NC DWR List of Approved PAMS/Flocculants.
2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated Stormwater before discharging offsite.
5. Store flocculants in leak -proof containers that are kept under storm -resistant cover or
surrounded by secondary containment structures.

and approval. If local standard details are not available, use one of the two types of
temporary concrete washouts provided on this detail.
5. Do not use concrete washouts for dewatering or storing defective curb or sidewalk
sections. Stormwater accumulated within the washout may not be pumped into or
discharged to the storm drain system or receiving surface waters. Liquid waste must
be pumped out and removed from project.
6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless it
can be shown that no other alternatives are reasonably available. At a minimum,
install protection of storm drain inlet(s) closest to the washout which could receive
spills or overflow.
7. Locate washouts in an easily accessible area, on level ground and install a stone
entrance pad in front of the washout. Additional controls may be required by the
approving authority.
8. Install at least one sign directing concrete trucks to the washout within the project
limits. Post signage on the washout itself to identify this location.
9. Remove leavings from the washout when at approximately 75% capacity to limit
overflow events. Replace the tarp, sand bags or other temporary structural
components when no longer functional. When utilizing alternative or proprietary
products, follow manufacturer's instructions.
10. At the completion of the concrete work, remove remaining leavings and dispose of in
an approved disposal facility. Fill pit, if applicable, and stabilize any disturbance
caused by removal of washout.
EQUIPMENT AND VEHICLE MAINTENANCE
1. Maintain vehicles and equipment to prevent discharge of fluids.
2. Provide drip pans under any stored equipment.
3. Identify leaks and repair as soon as feasible, or remove leaking equipment from the
project.
4. Collect all spent fluids, store in separate containers and properly dispose as hazardous
waste (recycle when possible).
5. Remove leaking vehicles and construction equipment from service until the problem
has been corrected.
6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products to
a recycling or disposal center that handles these materials.
LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE
1. Never bury or burn waste. Place litter and debris in approved waste containers.
2. Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
3. Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
4. Locate waste containers on areas that do not receive substantial amounts of runoff from
upland areas and does not drain directly to a storm drain, stream or wetland.
5. Cover waste containers at the end of each workday and before storm events or provide
secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
7. Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
8. Dispose waste off -site at an approved disposal facility.
9. On business days, clean up and dispose of waste in designated waste containers.

unless no other alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet away from storm drains, streams
or wetlands unless there is no alternative reasonably available. If 50 foot offset is not
attainable, provide relocation of portable toilet behind silt fence or place on a gravel pad
and surround with sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize a
licensed sanitary waste hauler to remove leaking portable toilets and replace with
properly operating unit.

SPECIFICATIONS: 1 Ensure that the subgrade for the filter and riprap follows
the required lines and grades as shown in the plan. Compact any
fill required in the subgrade to the
density of the surrounding
undisturbed material. Low areas in
the subgrade on undisturbed
soil may also be filled by increasing
the riprap thickness.
2 The riprap and gravel filter must
conform to the specified
grading limits shown on the plans.
3 Filter cloth, when used, must meet design requirements and be
properly protected form punching or
tearing during installation. Repair
any damage by removing the riprap
and placing another piece of filter
cloth over the damaged area. All connecting joints should overlap a
minimum of 1 ft. If the damage is
extensive, replace the entire
filter cloth.
4 Riprap may be placed by equipment, but take care to avoid damaging
the filter.
5 The minimum thickness of the riprap should be 1.5 times the
maximum stone diameter.
6 Riprap may be field stone or rough quarry stone. It should be
hard, angular, highly weather -resistant and well graded.
7 Construct the apron on zero grade with no overfall at the end. Make
the top of the riprap at the downstream end level with the receiving
area or slightly below it.
8 Ensure that the apron is properly aligned with the receiving stream
and preferably straight throughout its length. if a curve is needed to
fit site conditions, place it in the upper section of the apron.
9 Immediately after construction, stabilize all disturbed areas with vegetation.
MAINTENANCE: Inspect riprap outlet structures after heavey rains 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.

EVENT. IMMEDIATELY MAKE REPAIRS. IT IS PARTICULARLY IMPORTANT TO CHECK THE CHANNEL OUTLET
FOR BANK STABILITY AND EVIDENCE OF PIPING OR SCOUR HOLES. REMOVE ALL SIGNIFICANT SEDIMENT
ACCUMULATIONS TO MAINTAIN THE DESIGNED CARRYING CAPACITY.

CONSTRUCTION SPECIFICATIONS
1. CLEAR THE FOUNDATION AREA OF TREES, STUMPS, ROOTS, LOOSE ROCK, AND OTHER OBJECTIONABLE MATERIAL.
2. EXCAVATE THE CROSS SECTION TO THE LINES AND GRADES OF THE FOUNDATION OF THE LINER AS SHOWN ON THE PLANS.
BRING OVER -EXCAVATED AREAS TO GRADE BY INCREASING THE THICKNESS OF THE LINER OR BY BACKFILLING WITH MOIST
SOIL COMPACTED TO THE DENSITY OF THE SURROUNDING MATERIAL.
3. SUBGRADE PREPARATION --PREPARE THE SUBGRADE FOR RIPRAP AND FILTER TO THE REQUIRED LINES AND GRADES
SHOWN ON THE PLANS. COMPACT ANY FILL REQUIRED IN THE SUBGRADE TO A DENSITY APPROXIMATING THAT OF THE
SURROUNDING UNDISTURBED MATERIAL OR OVERFILL DEPRESSIONS WITH RIPRAP. REMOVE BRUSH, TREES, STUMPS, AND
OTHER OBJECTIONABLE MATERIAL. CUT THE SUBGRADE SUFFICIENTLY DEEP THAT THE FINISHED GRADE OF THE RIPRAP
WILL BE AT THE ELEVATION OF THE SURROUNDING AREA. CHANNELS SHOULD BE EXCAVATED SUFFICIENTLY TO ALLOW
PLACEMENT OF THE RIPRAP IN A MANNER SUCH THAT THE FINISHED INSIDE DIMENSIONS AND GRADE OF THE RIPRAP MEET
DESIGN SPECIFICATIONS.
4. SAND AND GRAVEL FILTER BLANKET --PLACE THE FILTER BLANKET IMMEDIATELY AFTER THE GROUND FOUNDATION IS
PREPARED. FOR GRAVEL, SPREAD FILTER STONE IN A UNIFORM LAYER TO THE SPECIFIED DEPTH. WHERE MORE THAN ONE
LAYER OF FILTER MATERIAL IS USED, SPREAD THE LAYERS WITH MINIMAL MIXING.
5. SYNTHETIC FILTER FABRIC --PLACE THE CLOTH FILTER DIRECTLY ON THE PREPARED FOUNDATION. OVERLAP THE EDGES BY
AT LEAST 12 INCHES, AND SPACE ANCHOR PINS EVERY 3 FT ALONG THE OVERLAP. BURY THE UPSTREAM END OF THE
CLOTH A MINIMUM OF 12 INCHES BELOW GROUND AND WHERE NECESSARY, BURY THE LOWER END OF THE CLOTH OR
OVERLAP WITH THE NEXT SECTION AS REQUIRED. SEE FIGURE 6.14A PAGE 6.14.6. TAKE CARE NOT TO DAMAGE THE CLOTH
WHEN PLACING RIPRAP. IF DAMAGE OCCURS REMOVE THE RIPRAP, AND REPAIR THE SHEET BY ADDING ANOTHER LAYER OF
FILTER MATERIAL WITH A MINIMUM OVERLAP OF 12 INCHES AROUND THE DAMAGED AREA. IF EXTENSIVE DAMAGE IS
SUSPECTED, REMOVE AND REPLACE THE ENTIRE SHEET. WHERE LARGE STONES ARE USED OR MACHINE PLACEMENT IS
DIFFICULT, A 4-INCH LAYER OF FINE GRAVEL OR SAND MAY BE NEEDED TO PROTECT THE FILTER CLOTH.
6. STONE PLACEMENT --PLACEMENT OF RIPRAP SHOULD FOLLOW IMMEDIATELY AFTER PLACEMENT OF THE FILTER. PLACE
RIPRAP SO THAT IT FORMS A DENSE, WELL -GRADED MASS OF STONE WITH A MINIMUM OF VOIDS. THE DESIRED
DISTRIBUTION OF STONES THROUGHOUT THE MASS MAY BE OBTAINED BY SELECTIVE LOADING AT THE QUARRY, AND
CONTROLLED DUMPING DURING FINAL PLACEMENT. PLACE RIPRAP TO ITS FULL THICKNESS IN ONE OPERATION. DO NOT
PLACE RIPRAP BY DUMPING THROUGH CHUTES OR OTHER METHODS THAT CAUSE SEGREGATION OF STONE SIZES. TAKE
CARE NOT TO DISLODGE THE UNDERLYING BASE OR FILTER WHEN PLACING THE STONES. THE TOE OF THE RIPRAP SLOPE
SHOULD BE KEYED TO A STABLE FOUNDATION AT ITS BASE AS SHOWN IN FIGURE 6.15B. THE TOE SHOULD BE EXCAVATED
TO A DEPTH ABOUT 1.5 TIMES THE DESIGN THICKNESS OF THE RIPRAP, AND SHOULD EXTEND HORIZONTALLY FROM THE
SLOPE. THE FINISHED SLOPE SHOULD BE FREE OF POCKETS OF SMALL STONE OR CLUSTERS OF LARGE STONES. HAND
PLACING MAY BE NECESSARY TO ACHIEVE THE PROPER DISTRIBUTION OF STONE SIZES TO PRODUCE A RELATIVELY
SMOOTH, UNIFORM SURFACE. THE FINISHED GRADE OF THE RIPRAP SHOULD BLEND WITH THE SURROUNDING AREA. NO
OVERFALL OR PROTRUSION OF RIPRAP SHOULD BE APPARENT.
7. PLACE FILTERS, BEDDINGS, AND FOUNDATION DRAINS TO LINE AND GRADE IN THE MANNER SPECIFIED. PLACE FILTER AND
BEDDING MATERIALS IMMEDIATELY AFTER SLOPE PREPARATION. FOR SYNTHETIC FILTER FABRICS, OVERLAP THE
DOWNSTREAM EDGE BY AT LEAST 12 INCHES WITH THE UPSTREAM EDGE WHICH IS BURIED A MINIMUM 12 INCHES IN A
TRENCH. SEE FIGURE 6.14A, PAGE 6.14.6. SPACE ANCHOR PINS EVERY 3 FEET ALONG THE OVERLAP. SPREAD GRANULAR
MATERIALS IN A UNIFORM LAYER. WHEN MORE THAN ONE GRADATION IS REQUIRED, SPREAD THE LAYERS SO THERE IS
MINIMAL MIXING. FILTER MATERIAL SHOULD CONSIST OF AT LEAST 3 INCHES OF MATERIAL ON ALL SIDES OF THE DRAIN
PIPE. THE DRAIN PIPE CONDUIT SHOULD BE A MINIMUM OF 4 INCHES IN DIAMETER. ACCEPTABLE MATERIALS INCLUDE
PERFORATED, CONTINUOUS, CLOSED -JOINT CONDUITS OF CLAY, CONCRETE, METAL, PLASTIC, OR OTHER SUITABLE
MATERIAL (PRACTICE 6.81, SUBSURFACE DRAIN).
8. PERFORM ALL CHANNEL CONSTRUCTION TO KEEP EROSION AND WATER POLLUTION TO A MINIMUM. IMMEDIATELY UPON
COMPLETION OF THE CHANNEL, VEGETATE ALL DISTURBED AREAS OR OTHERWISE PROTECT THEM AGAINST SOIL EROSION.
WHERE CHANNEL CONSTRUCTION WILL TAKE LONGER THAN 30 DAYS, STABILIZE CHANNELS BY REACHES.
MAINTENANCE
INSPECT CHANNELS AT REGULAR INTERVALS AS WELL AS AFTER MAJOR RAINS, AND MAKE REPAIRS PROMPTLY. GIVE SPECIAL
ATTENTION TO THE OUTLET AND INLET SECTIONS AND OTHER POINTS WHERE CONCENTRATED FLOW ENTERS. CAREFULLY
CHECK STABILITY AT ROAD CROSSINGS, AND LOOK FOR INDICATIONS OF PIPING, SCOUR HOLES, OR BANK FAILURES. MAKE
REPAIRS IMMEDIATELY. MAINTAIN ALL VEGETATION ADJACENT TO THE CHANNEL IN A HEALTHY, VIGOROUS CONDITION TO
PROTECT THE AREA FROM EROSION AND SCOUR DURING OUT -OF -BANK FLOW.

CONSTRUCTION 1 Remove and properly dispose of all trees, brush, stumps,
SPECIFICATIONS and other objectionable material.
2 Ensure that the minimum constructed cross section meets
all design requirements.
3 Ensure that the top of the dike is not lower at any point
than the design elevation plus the specified settlement.
4 Provide sufficient room around diversions to permit machine
regrading and cleanout.
5 Vegetate the ridge immediately after construction.
MAINTENANCE Inspect diversions once a week and after every rainfall.
Immediately remove sediment from the flow area and repair
the diversion ridge. Carefully check outlets and make timely
repairs as needed. When the area protected is permanently
stabilized.
