SCAPE CONTRACTOR SHALL PROVIDE PLANT MATERIAL FROM LOCAL SOURCE TO
RE SURVIVABILITY. CONTRACTOR TO PROVIDE SOURCE OF PLANT MATERIAL AND
TION FOR APPROVAL PRIO TO INSTALLATION OF MATERIAL
41MUM TWO-YEAR WARRANTY PERIOD SHALL BE PROVIDED FOR PLANT SURVIVAL
REPLACEMENT. AT THE END OF THE FIRST YEAR AND AGAIN AT THE END OF
2ND YEAR, ALL PLANTS THAT DO NOT SURVIVE MUST BE REPLACED.
HAVE SOIL SAMPLES ANALYZED BY EXPERIENCED AND QUALIFIED INDIVIDUALS, SUCH AS
THOSE AT THE AGRICULTURAL EXTENSION OFFICE, WHO WILL EXPLAIN IN WRITING THE
RESULTS, WHAT THEY MEAN, AS WELL AS WHAT SOIL AMENDMENTS WOULD BE
REQUIRED. CERTAIN SOIL CONDITIONS, SUCH AS MARINE CLAYS, CAN PRESENT SERIOUS
CONSTRAINTS TO THE GROWTH OF PLANT MATERIALS AND MAY REQUIRE THE GUIDANCE
OF QUALIFIED PROFESSIONALS. WHEN POOR SOILS CANNOT BE AMENDED, SEED MIXES
AND PLANT MATERIAL MUST BE SELECTED TO ESTABLISH GROUND COVER AS QUICKLY
AS POSSIBLE. AT A MINIMUM, HAVE THE SOILS TESTED AS FOLLOWS:
PH- WHETHER ACID, NEUTRAL, OR ALKALINE
MAJOR SOIL NUTRIENTS- NITROGEN, PHOSPHORUS, POTASSIUM
MINERALS- SUCH AS CHELATED IRON, LIME
AREAS THAT RECENTLY HAVE BEEN INVOLVED IN CONSTRUCTION CAN BECOME
COMPACTED SO THAT PLANT ROOTS CANNOT PENETRATE THE SOIL ALSO, SEEDS WILL
UE ON THE SURFACE OF COMPACTED SOILS AND ARE OFTEN WASHED AWAY OR EATEN
BY BIRDS. FOR PLANTING SUCCESS, SOILS SHOULD BE LOOSENED TO A DEPTH OF
THREE TO FIVE INCHES. HARD SOILS MAY REQUIRE DISKING TO A DEEPER DEPTH. THE
SOIL SHOULD BE LOOSENED REGARDLESS OF THE GROUND COVER. THIS WILL IMPROVE
SEED CONTACT WITH THE SOIL, INCREASE GERMINATION RATES, AND ALLOW THE ROOTS
TO PENETRATE THE SOIL FOR AREAS TO BE SODDED, DISKING IS NECESSARY SO THAT
THE ROOTS CAN PENETRATE THE SOIL PROVIDING GOOD GROWING CONDITIONS CAN
PREVENT POOR VEGETATIVE COVER. THIS SAVES MONEY BECAUSE VEGETATION WILL NOT
NEED TO BE REPLANTED.
IF TOPSOIL HAS BEEN STOCKPILED IN DEEP MOUNDS FOR A LONG PERIOD OF TIME, IT
IS NECESSARY TO TEST THE SOIL FOR PH AS WELL AS MICROBIAL ACTIVITY. IF THE
MICROBIAL ACTIVITY HAS BEEN DESTROYED, IT IS NECESSARY TO INOCULATE THE SOIL
AFTER APPLICATION.
REMEMBER THAT NEWLY INSTALLED PLANT MATERIAL REQUIRES WATER IN ORDER TO
RECOVER FROM THE SHOCK OF BEING TRANSPLANTED. BE SURE THAT SOME SOURCE
OF WATER IS PROVIDED, ESPECIALLY DURING DRY PERIODS. THIS WILL REDUCE PLANT
LOSS AND PROVIDE THE NEW PLANT MATERIALS WITH A CHANCE TO ESTABLISH ROOT
GROWTH.
PLANTING TO TAKE PLACE ONLY AFTER POND CONSTRUCTION IS COMPLETE AND UPLAND SLOPES HAVE
BEEN EITHER HYDRO MULCHED OR MATTING INSTALLED (NAG S75 BN MINIMUM).
NON -CLUMPING TURF GRASSES SHALL BE PLANTED ON WATER IMPOUNDING DAMS AND BERMS, IT IS
RECOMMENDED THAT PERENNIAL GRASSES SUCH AS HYBRID BERMUDA OR CENTIPEDE ARE USED IN
THE COASTAL PLAIN AND PIEDMONT.
VEGETATIVE H F PLANTING REQUIREMENTS
MINIMUM PLANT DENSITY OF 50 PLANTS / 200 SF. SHELF AREA IS APPROXIMATELY 3,088 SF
THEREFORE A MINIMUM OF 772 PLANTS SHOULD BE INSTALLED. SUGGEST PLANTING 864 PLANTS

AFTER THE INITIAL PLANTING, BE CAREFUL NOT TO RAISE THE WATER LEVEL TO
MORE THANABOUT 1 IN (2 TO 3 CM) ABOVE THE SUBSTRATE. TOO MUCH WATER
AT THIS TIME MAY STRESS THE NEW PLANTS. MAINTAIN THE WATER AT ABOUT 1
IN (2 TO 3 CM) FOR ABOUT ONE WEEK, THIS WILL INHIBIT THE GERMINATION AND
GROWTH OF ANY TERRESTRIAL SPECIES THAT MAY BE PRESENT. THE WATER
LEVEL CAN THEN BE LOWERED TO THE SUBSTRATE SURFACE FOR 15 TO 20
DAYS. THIS WILL EXPOSE THE MUD SURFACE, STIMULATING ANY WETLAND SEEDS
THAT WERE BROUGHT IN WITH YOUR TRANSPLANTS TO GERMINATE AS WELL AS
INCREASE THE RATE OF SPREAD OF THE TRANSPLANTS. YOU CAN THEN RAISE
THE WATER LEVEL 1 TO 2 IN (3 TO 5 CM). FOR ANOTHER WEEK. THEN LOWER
THE WATER TO THE SUBSTRATE SURFACE FOR ANOTHER 15 TO 20 DAYS. AFTER
THIS PERIOD, SLOWLY RAISE THE WATER LEVEL TO 4 TO 6 IN (10 TO 15 CM).
FOR 3 TO 5 DAYS. REMEMBER THAT THE AERENCHYMOUS TISSUES IN THE PLANT
SHOOTS ARE WHAT SUPPLY THE ROOTS WITH OXYGEN SO BE CAREFUL NOT TO
RAISE THE WATER OVER THE TOPS OF THE EMERGENT VEGETATION. WHEN IN
DOUBT, DEFER TO THE HYDROLOGY CONDITIONS ON NATURAL REFERENCE SITES
WHERE THE SPECIES OCCURS.

INSTALLATION:
NOTE SEDIMENT FENCE CAPTURES SEDIMENT BY BACKING UP WATER TO ALLOW DEPOSITION. IT IS RELATIVELY
INEFFECTIVE FOR FILTRATION BECAUSE IT CLOGS TOO RAPIDLY. tEH SEDIMENTATION POOL BEHIND THE FENCE IS VERY
EFFECTIVE AND MAY REDUCE THE NEED FOR EXPENSIVE SEDIMENT BASINS AND TRAPS.
TO USE SEDIMENT FENCE EFFECTIVELY, PROVIDE ACCESS TO LOCATIONS WHERE SEDIMENT ACCUMULATES AND PROVIDE
REINFORCED, STABILIZED OUTLETS FOR EMERGENCY OVERFLOW (SEE DETAIL).
SEDIMENT FENCE IS MOST EFFECTIVE WHEN USED IN CONJUNCTION WITH OTHER PRACTICES SUCH AS PERIMETER DIKES
OR DIVERSIONS.
LOCATION:
LOCATE THE FENCE AT LEAST 10 FT. FROM THE TOE OF STEEP SLOPES TO PROVIDE SEDIMENT STORAGE AND ACCESS
FOR CLEANOUT (SEE DETAIL).
THE FENCE UNE SHOULD BE NEARLY LEVEL THROUGH MOST OF ITS LENGTH TO IMPOUND A BROAD, TEMPORARY POOL
STABILIZED OUTLETS ARE REQUIRED FOR BYPASS FLOW, UNLESS FENCE IS DESIGNED TO RETAIN ALL RUNOFF FROM THE
10-YR STORM (SEE DETAIL).
THE FENCE UNE MAY RUN SUGHTLY OFF LEVEL (GRADE LESS THAN IX) IF IT TERMINATES IN A LEVEL SECTION WITH A
STABIUZED OUTLET, DIVERSION, BASIN, OR SEDIMENT TRAP. THERE MUST BE NO GULLYING ALONG THE FENCE OR AT
THE ENDS. SEDIMENT FENCE SHOULD NOT BE USED AS A DIVERSION.
CONSTRUCTION:
DIG A TRENCH APPROXIMATELY 8 INCHES DEEP AND 4 INCHES WIDE, OR A V-TRENCH, IN THE LINE OF THE FENCE AS
SHOWN IN DETAIL
DRIVE POSTS SECURELY, AT LEAST 18 INCHES INTO THE GROUND, ON THE DOWNSLOPE SIDE OF THE TRENCH. SPACE
POSTS A MAXIMUM OF 8 FT. IF FENCE IS SUPPORTED BY WIRE, 6 FT. 1F EXTRA -STRENGTH FABRIC IS USED WITHOUT
SUPPORT WIRE. ADJUST SPACING TO PLACE POSTS AT LOW POINTS ALONG THE FENCEUNE.
FASTEN SUPPORT WIRE FENCE TO UPSLOPE SIDE OF POSTS, EXTENDING 6 INCHES INTO THE TRENCH AS SHOWN IN
DETAIL
ATTACH CONTINUOUS LENGTH OF FABRIC TO UPSLOPE SIDE OF FENCE POSTS. AVOID JOINTS, PARTICULARLY AT LOW
POINTS IN THE FENCE LINE. WHERE JOINTS ARE NECESSARY, FASTEN FABRIC SECURELY TO SUPPORT POSTS AND
OVERLAP TO THE NEXT POST.

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 UNED 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 B-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 SLICED: OTHERWISE WATER CAN GET UNDER THE
FABRIC. IF THE LENGTH OF THE FABRIC 15 INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS,
SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTIONS(S) SHOULD OVERLAP THE LOWER SECTION(S) SO
THAT WATER CANNOT FLOW UNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH

It.
AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE BEEN PERMANENTLY STABIUZED. REMOVE THE STRUCTURE AND ALL
THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE PROPERLY.
MAINTENANCE
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.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR AROUND
THEM.
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 THESE 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
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. CHECK THE FABRIC UNED 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 REPAIR IMMEDIATELY. REMOVE ALL
TRASH AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS.
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.

Grades- Either a uniform or a gradually increasing grade is preferred.
Sudden decreases in grade accumulate sediment and should be expected to
cause overtopping. A large increase in grade may erode.
OutleF Design the outlet to accept flow from the diversion plus any other
contributing areas. Divert sediment -laden runoff and release through a
sediment -trapping device (Practice 6.60, Temporary Sediment DW and
Practice6.61, Sediment Basin). Flow from undisturbed areas can be dispersed
by a level spreader (Practice 6.40, Level Spreader).
Small diversions -Where the diversion channel grade is between 0.2 and
3%, a permanent vegetative raver is required. A parabolic channel and ridge
1.5 feet deep and 12 feet wide may be used for diversions with flows up to 5
cfs. This depth does not include freeboard or settlement Side slopes should
be 3:1 or flatter, and the top of the dike must be at least 2 feet wide.
Construction 1. Remove and properly dispose of all trees, brush, stumps, and other
Specifications 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, unless it will remain in
place less than 30 working days.
Maintenance Inspect temporary 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, remove the ridge and the channel to blend with the
natural ground level and appropriately stabilize it.

Specifications Even if properly designed, if not properly installed, RECP's will probably
not function as desired. Proper installation is imperative. Even if properly
installed, if not properly timed and nourished, vegetation will probably not
grow as desired. Proper seed/vegetation selection is also imperative.
Grade the surface of installation areas so that the ground is smooth and loose.
When seeding prior to installation, follow the steps for seed bed preparation,
soil amendments, and seeding in Surface Stabilization, 6.1. All gullies, rills,
and any other disturbed areas must be fine graded prior to installation. Spread
seed before RECP installation. (important: Remove all large rocks, dirt clods,
stumps, roots, grass clumps, trash, and other obstructions from the soil surface
to allow for direct contact between the soil surface and the RECP.)
Terminal anchor trenches are required at RECP ends and intermittent trenches
must be constructed across channels at 25-foot intervals. Terminal anchor
trenches should be a minimum of 12 inches in depth and 6 inches in width,
while intermittent trenches need be only 6 inches deep and 6 inches wide.
Installation for Slopes- Place the RECP 2-3 feet over the top of the slope
and into an excavated end trench measuring approximately 12 inches deep
by 6 inches wide. Pin the RECP at 1 foot intervals along the bottom of the
trench, backfill, and compact Unroll the RECP down (or along) the slope
maintaining direct contact between the soil and the RECP. Overlap adjacent
rolls a minimum of 3 inches. Pin the RECP to the ground using staples or
pins in a 3 foot center -to -center pattern.. Less frequent stapling/pinning is
acceptable on moderate slopes.
Installation in Channels- Excavate terminal trenches (12 inches deep and 6
inches wide) across the channel at the upper and lower end of the lined channel
sections. At 25-foot intervals along the channel, anchor the RECP across the
channel either in 6 inch by 6 inch trenches or by installing two closely spaced
rows of anchors. Excavate longitudinal trenches 6 inches deep and wide along
channel edges (above water line) in which to bury the outside RECP edges.
Place the first RECP at the downstream end of the channel. Place the end of
the first RECP in the terminal trench and pin it at 1 foot intervals along the
bottom of the trench.
Note: The RECP should be placed upside down in the trench with the roll on
the downstream side of the bench.
Once pinned and backfilled, the RECP is deployed by wrapping over the
top of the trench and unrolling upstream. If the channel is wider than the
provided rolls, place ends of adjacent rolls in the terminal trench, overlapping
the adjacent rolls a minimum of 3 inches. Pin at 1 foot intervals, backfill, and
compact. Unroll the RECP in the upstream direction until reaching the first
intermittent trench. Fold the RECP back over itself, positioning the roll on
the downstream side of the trench, and allowing the mat to conform to the
trench.
Than pin the RECP (two layers) to the bottom of the trench, backfill, and
compact Continue up the channel (wrapping over the top of the intermittent
trench) repeating this step at other intermittent trenches, until reaching the
upper terminal trench.
At the upper terminal trench, allow the RECP to conform to the trench,
secure with pins or staples, backfill, compact and then bring the mat back
over the top of the trench and onto the existing mat (2 to 3 feet overlap in the
downstream direction), and pin at i foot intervals across the RECP. When
starting installation of a new roll, begin in a trench or shingle -lap ends of rolls
a minimum of i foot with upstream RECP on top to prevent uplifting. Place
the outside edges of the RECP(s) in longitudinal trenches, pin, backfill, and
compact.
Anchoring Devices-11 gauge, at least 6 inches length by 1 inch width staples
or 12 inch minimum length wooden stakes are recommended for anchoring the
1. Inspect Rolled Erosion Control Products at least weekly and after each
significant (1/2 inch or greater) rain fall event repair immediately.
2. Good contact with the ground must be maintained, and erosion must not
occur beneath the RECP.
3. Any areas of the RECP that are damaged Or not in close contact with the
ground shall be repaired and stapled.
4. If erosion occurs due to poorly controlled drainage, the problem shall be
fixed and the eroded area protected.
5. Monitor and repair the RECP as necessary until ground cover is
established.

RECP to the ground
Drive staples or pins so that the top of the staple or pin is flush with the ground
surface. Anchor each RECP every 3 feet along its center. Longitudinal
overlaps must be sufficient to accommodate a row of anchors and uniform
along the entire length of overlap and anchored every 3 feet along the overlap
length. Roll ends may be spliced by overlapping 1 foot (in the direction of
water flow), with the upstream/upslope mat placed on top of the downstream/
downslope RECP. This overlap should be anchored at 1 foot spacing across
the RECP. When installing multiple width mats heat seamed in the factory, all
factory seams and field overlaps should be similarly anchored.

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanentground 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.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
• Temporary grass seed covered with straw or • Permanent grass seed covered with straw or
other mulches and tackifiers other mulches and tackifiers
• Hydroseseding a Geotextile fabrics such as permanent soil
• Rolled erosion control products with or reinforcement matting
without temporary grass seed • Hydroseeding
• 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
a 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/Flocculonts.
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/Flocculonts 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.

EROSION CONTROL NOTES AND MAINTENANCE PLAN
1. ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED
FOR STABILITY AND OPERATION FOLLOWING EVERY RUNOFF -PRODUCING
RAINFALL, BUT IN NO CASE, LESS THAN ONCE EVERY WEEK AND WITHIN
24 HOURS OF EVERY HALF -INCH RAINFALL
2. ALL POINTS OF EGRESS WILL HAVE CONSTRUCTION ENTRANCES THAT
WILL BE PERIODICALLY TOP -DRESSED WITH AN ADDITIONAL 2 INCHES OF
#4 STONE TO MAINTAIN PROPER DEPTH. THEY WILL BE MAINTAINED IN A
CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING THE SITE.
IMMEDIATELY REMOVE OBJECTIONABLE MATERIAL SPILLED WASHED OR
TRACKED ONTO THE CONSTRUCTION ENTRANCE OR ROADWAYS.
3. SEDIMENT WILL BE REMOVED FROM HARDWARE CLOTH AND GRAVEL
INLET PROTECTION, BLOCK AND GRAVEL INLET PROTECTION, ROCK
DOUGHNUT INLET PROTECTION AND ROCK PIPE INLET PROTECTION WHEN
THE DESIGNED STORAGE CAPACITY HAS BEEN HALF FILLED WITH
SEDIMENT. ROCK WILL BE CLEANED OR REPLACED WHEN THE SEDIMENT
POOL NO LONGER DRAINS AS DESIGNED. DEBRIS WILL BE REMOVED
FROM THE ROCK AND HARDWARE CLOTH TO ALLOW PROPER DRAINAGE.
SILT SACKS WILL BE EMPTIED ONCE A WEEK AND AFTER EVERY RAIN
EVENT. SEDIMENT WILL BE REMOVED FROM AROUND BEAVER DAMS,
DANDY SACKS AND SOCKS ONCE A WEEK AND AFTER EVERY RAIN EVENT.
4. DIVERSION DITCHES WILL BE CLEANED OUT IMMEDIATELY TO REMOVE
SEDIMENT OR OBSTRUCTIONS FROM THE FLOW AREA. THE DIVERSION
RIDGES WILL ALSO BE REPAIRED. SWALES MUST BE TEMPORARILY
STABILIZED WITHIN 21 CALENDAR DAYS OF CEASE OF ANY PHASE OF
ACTIVITY ASSOCIATED WITH A SWALE.
5. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE
WHEN IT BECOMES 1/3 FILLED. THE SEDIMENT FENCE WILL BE
REPAIRED AS NECESSARY TO MAINTAIN A BARRIER. STAKES MUST BE
STEEL STAKE SPACING WILL BE 6 FEET MAX. WITH THE USE OF EXTRA
STRENGTH FABRIC, WITHOUT WIRE BACKING. STAKE SPACING WILL BE 8
FEET MAX. WHEN STANDARD STRENGTH FABRIC AND WIRE BACKING ARE
USED. IF ROCK FILTERS ARE DESIGNED AT LOW POINTS IN THE
SEDIMENT FENCE, THE ROCK WILL BE REPAIRED OR REPLACED IF IT
BECOMES HALF -FULL OF SEDIMENT, NO LONGER DRAINS AS DESIGNED
OR IS DAMAGED.
6. SEDIMENT WILL BE REMOVED FROM SEDIMENT TRAPS WHEN THE
DESIGNED STORAGE CAPACITY HAS BEEN HALF FILLED WITH SEDIMENT.
THE ROCK WILL BE CLEANED OR REPLACED WHEN THE SEDIMENT POOL
NO LONGER DRAINS OR WHEN THE ROCK IS DISLODGED. BAFFLES WILL
BE REPAIRED OR REPLACED IF THEY COLLAPSE, TEAR, DECOMPOSE OR
BECOME INEFFECTIVE. THEY WILL BE REPLACED PROMPTLY. SEDIMENT
WILL BE REMOVED WHEN DEPOSITS REACH HALF THE HEIGHT OF THE 1ST
BAFFLE. FLOATING SKIMMERS WILL BE INSPECTED AND KEPT CLEAN
WEEKLY.
7. RESTORE RETENTION POND TO DESIGN CONTOURS AND ELEVATIONS
PRIOR TO COMPLETION OF THE PROJECT.
8. ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY
AND MULCHED ACCORDING TO SPECIFICATIONS IN THE VEGETATIVE PLAN
TO MAINTAIN A VIGOROUS, DENSE VEGETATIVE COVER. ALL SLOPES WILL
BE STABILIZED WITH 21 CALENDAR DAYS. ALL OTHER AREAS WILL BE
STABILIZED WITH 15 WORKING DAYS.
9. FL.000ULANTS WILL BE USED TO ADDRESS TURBIDITY ISSUES. THE
PUMPS, TANKS, HOSES AND INJECT SYSTEMS WILL BE CHECKED FOR
PROBLEMS OR TURBID DISCHARGES DAILY.
EROSION CONTROL CONSTRUCTION SEQUENCE
1. INSTALL SILT FENCE AS FIRST PART OF THE WORK.
EXCAVATE THE RETENTION POND AND INSTALL 3 TEMPORARY
BAFFLES TO ACT AS SEDIMENT STORAGE.
2. INSTALL STORMDRAINAGE TO DIRECT RUNOFF TO THE RETENTION
POND.
3. CLEAR REST OF SITE AND CONSTRUCT THE BUILDING, PAVEMENT
AND UTILITIES.
4. RESTORE RETENTION POND TO DESIGN CONTOURS AND ESTABLISH
PERMANENT VEGETATION.
