• TREES WITHIN VEHICULAR SIGHT LINES, AS ILLUSTRATED ON THE LANDSCAPE PLAN, ARE TO BE TRIMMED
TO A CLEARANCE HEIGHT OF 7 FT. (FROM ALL PAVED, TRAVELED SURFACES), OR AS OTHERWISE
INDICATED ON THE PLANS.
• VEGETATIVE GROUND COVER, SHRUBS AND ORNAMENTAL PLANTS AND GRASSES MUST BE TRIMMED SO
THAT NO PORTION OF THE PLANT EXCEEDS 30 INCHES ABOVE GRADE (OF ALL PAVED, TRAVEL
SURFACES) ALONG AND WITHIN THE SIGHT LINES OF PARKING LOTS AND INGRESS -EGRESS WAYS.
• FALLEN PLANT FLOWERS, FRUIT, SEEDS AND DEBRIS DROPPINGS ARE TO BE REMOVED IMMEDIATELY

NOTES:
1) 50 PLANTS PER 200 SQUARE FEET OF AREA PER CODE REQUIREMENTS.
2) PLANTING RATIO IS BASED ON THE AREA, NOT THE TOTAL QUANTITY OF THE PLANTS. THE QUANTITY OF EACH PLANT IS
DETERMINED BY THE AREA RATIO AND THE SPACING IN WHICH THEY ARE TO BE PLANTED.
3) PLANTING OF BASIN IS NOT TO BE CONDUCTED UNTIL THE ACTUAL WATER LEVEL OF THE BASIN AND ALL SURROUNDING AREAS
HAVE STABILIZED. PRIOR TO PLANTING, CONTRACTOR TO VERIFY THE WATER DEPTH TO THE NEAREST INCH. PLANTING AREA MAY
NEED TO BE REVISED AND PLANT QUANTITIES ADJUSTED BASED ON FIELD CONDITIONS.

INSTRUCTIONS FOR
SILT FENCE
YNSTALLATION
1. REFER TO THE PLANS FOR LOCATION, EXTENT, AND SPECIFICATIONS. IF
THERE ARE QUESTIONS OP PROBLEMS WITH THE LOCATION EXTENT OR
METHODS OF INSTALLATIGN, CONTACT THE ENGINEER, ARCHITECT,IOR
RESPONSIBLE PERSONNEL ON THE SITE FOR ASSISTANCE. EROSION
CONTROL PERSONNEL HAVE COPIES OF INSTRUCTIONS AND MAY HAVE
PHOTOGRAPHS OF PROPERLY INSTALLED SILT FENCES AS AN AID TO
INSTALLATION.
SF THE SILT FENCE IS NOT INSTALLED CORRECTLY THE FIRST TIME, IT
WILL HAVE TO BE REBUILT.
2. DETERMINE THE LOCATION ON THE GROUND TAKING INTO
CONSIDERATION:
* A SILT BARRIER (PREFABRICATED SILT FENCE) CANNOT BE
SUBSTITUTED! 1 THE SILT FENCE MUST BE CONSTRUCTED AS
DESCRIBED IN THESE INSTRUCTIONS.
* ALLOW SUFFICIENT SPACE FOR MAINTENANCE, GRADING, FILLING, AND
OTHER CONSTRUCTION ACTIVITY BETWEEN THE SILT FENCE AND THE
CONSTRUCTION SITE. IF NECESSARY, HAVE SLOPE STAKES, BUILDING
CORNERS, STORM DRAINS, ETC. SURVEYED BEFORE CLEARING TO GUIDE
INSTALLATION. KNOW WHERE THE TOE OF FILL SLOPES WILL EXTEND SO
THAT SUFFICIENT ROOM IS LEFT BETWEEN THE TOE AND SILT FENCE FOR
MAINTENANCE, REPAIR, AND REMOVAL.
* ALLOW AT LEAST:
15 FEET BETWEEN THE FENCE AND SINGLE -STORY BUILDINGS.
2s FEET BETWEEN THE FENCE AND MULTIPLE -STORY BUILDINGS.
10 FEET BETWEEN THE FENCE AND THE TOE OF FILL SLOPES.
* WHERE POSSIBLE, INSTALL THE SILT FENCE ON THE CONTOUR SO THAT
RUNOFF GOES THROUGH THE SILT FENCE AND DOES NOT FLOW ALONG THE
SILT FENCE AND POND AT THE LOWEST POINT. WHERE PONDING DOES
OCCUR, SILT FENCE OUTLETS MAY BE NECESSARY SO THAT THE FENCE
DOES NOT COLLAPSE.
3. CLEAR THE LOCATION OF THE SILT FENCE, CLEARING ONLY WHAT IS
NEEDED TO PROVIDE ACCESS TO PERSONNEL AND EQUIPMENT FOR
INSTALLATION. IT IS PERMISSIBLE TO PLACE THE SILT FENCE IN THE
EDGE OF EXISTING TREES AS LONG AS THE OWNER ALLOWS IT AND CARE
ELATION
IS TAKEN TO PROTECT THESE TREES DURING INSTA ,
MAINTENANCE, AND REMOVAL IF THE TREES ARE TO REMAIN AFTER
CONSTRUCTION. DO NOT ATTACH THE FILTER FABRIC TO THE TREES, AS
IT MAKES BURYING THE TOE IMPOSSIBLE.
4. EXCAVATE A 6 X 6 -INCH TRENCH ALONG THE LOCATION OF THE FENCE.
USING A "DITCH WITCH" IS HELPFUL.
s. ALo
NG THE LOWER SIDE OF THE TRENCH, PLACE STEEL FENCE POSTS NO
MORE THAN B FEET APART AND DRIVE THEM 18 INCHES INTO THE
GROUND.
6. ATTACH WIRE FENCE ("HOG WIRE" OF MINIMUM 14 GAUGE WITH MAXIMUM
MESH OF 6 INCHES) TO THE UPHILL SIDE OF THE POSTS, AND PLACE 12
INCHES OF THE BOTTOM OF THE FENCE INTO THE TRENCH. DO NOT USE
"CHICKEN WIRE." USE WIRE TO FASTEN THE FENCE TO THE POSTS. THE
COMPLETED FENCE MUST BE AT LEAST 2 FEET HIGH AND NOT MORE THAN
3 FEET HIGH.
7. ATTACH SYNTHETIC FILTER PHILL SIDE OF THE WIRE
IL R FABRIC TO THE U
FENCE WITH S A L P E 1
T P ES A MAXIMUM 12 INCHES APART, AND LAC 2
INCHES OF THE FABRIC INTO THE TRENCH WITH THE WIRE FENCE. USE
ROLLS OF FABRIC AND CUT TO THE NECESSARY LENGTH IN ORDER TO
MINIMIZE THE NUMBER OF JOINTS.
B. BACKFILL THE TRENCH AND TAMP THE FILL TO FIRMLY ANCHOR THE
BOTTOM OF THE FILTER FABRIC AND WIRE FENCE TO PREVENT WATER
FROM FLOWING UNDER THE FENCE; MARE IT GO THROUGH THE FILTER
FABRIC.
9. WHERE IT IS IMPOSSIBLE TO INSTALL THE SILT FENCE ON THE
CONTOUR, RUNOFF WILL FLOW ALONG THE FENCE AND POND AT THE
LOWEST POINT. WHERE THE TOTAL DRAINAGE AREA TO THE POINT OF
PONDING IS GREATER THAN 5,000 SQUARE FEET (FOR EXAMPLE: A
SQUARE 70 FEET ON A SIDE), A SILT FENCE OUTLET IS REQUIRED;
WHERE THE DRAINAGE AREA IS GREATER THAN 10,000 SQUARE FEET (FOR
EXAMPLE: A SQUARE 100 FEET ON A SIDE), A SEDIMENT TRAP IS
NEC
ESSARY. L

MATERIALS, EQUIPMENT, AND PERSONNEL MUST BE AVAILABLE FOR
MAINTENANCE AT ALL TIMES.
1. INSPECT THE SILT FENCE:
* IN CONSTRUCTION: TO SEE IF MACHINERY OR FALLING TREES HAVE
DAMAGED THE SILT FENCE; IF DAMAGED, REPAIR IT. TO SEE THAT FILL
MATERIAL HAS NOT ACCUMULATED AGAINST THE FENCE; IF IT HAS,
REMOVE THE MATERIAL, REPAIR THE FENCE, AND MOVE THE FENCE OR
FILL SO THAT IT DOES NOT HAPPEN AGAIN.
* AFTER EACH RAINFALL: TO SEE THAT RUNOFF IS NOT FLOWING UNDER
THE FENCE; IF IT IS, BURY THE BOTTOM OF THE FENCE CORRECTLY. TO
SEE THAT RUNOFF HAS NOT TOPPED THE FENCE IN LOW POINTS; IF IT
HAS, AN OUTLET MAY BE NEEDED AT THAT POINT TO PREVENT FUTURE
FAILURES.
2. CLEAN OUT ACCUMULATED SEDIMENT WHEN IT REACHES A DEPTH OF ONE-
HALF THE HEIGHT OF THE FILTER FABRIC. PLACE THE SEDIMENT IN A
DISPOSAL AREA OR, IF APPROPRIATE, MIX IT WITH DRY SOIL ON THE
SITE.
DO NOT DISPOSE OF SEDIMBNT IN A MANNER TEAT WILL CREATE AN
EROSION HAZARD. DO NOT ERECT A NEW SILT FENCE ON TOP OF
ACCUMULATED SEDIMENT BEHIND THE PENCE.
3. IF SILT FENCE OUTLETS ARE USED, REMOVE AND REPLACE THE STONE
FILTER WITH CLEAN, WASHED STONE WHEN THE FILTER BECOMES
CLOGGED. DISPOSE OF ANY CONTAMINATED STONE PROPERLY.
i
4. REPAIR ANY BREAKS OR ROTTEN PLACES IN THE FILTER FABRIC.
s. IF THE FENCE IS SAGGING BETWEEN POSTS, INSTALL ADDITIONAL
POSTS.
6. WHEN MAKING REPAIRS, ALWAYS RESTORE THE SILT FENCE TO ITS
ORIGINAL DESIGN CONFIGURATION.
REMOVAL
1. WHEN GRADING IN THE DRAINAGE AREA ABOVE THE SILT FENCE HAS BEEN
FINISHED AND DISTURBED AREAS SUFFICIENTLY STABILIZED TO

INSTALLATION
DETAIL
1. Prepare soil before installing rolled
erosion control products (RECPs),
including any necessary
application of lime, fertilizer, and
seed.
2 Begin at the top of the slope by
anchoring the RECPs in a
5"(15cm) deep X 6'(15em) wide
trench with approximately 12`
(30cm) of RECPs extended beyond
the up-slope portion or the trench.
Anchor the RECPs with a row of
stapleslstakes approximately 12'
(30cm) apart in the bottom of the
trench. Backfill and compact the
trench after sapling. Apply seed to
the compacted sail and told the
remaining 12"(30cm) portion of
RECPs back over the seed and
compacted soil. Secure RECPs
over campacted soil with a row
Of s'.aplesfstakes spaced
approximaWy 12'(30cm) apart
across the width of the RECPs.
3. Roil the RECPs (A) down or (B)
horizontally across the slope.
RECPs will unrodl with appropriate
side against the soil surface. All
R ---CP-, must be securely fastened
to soli surface by plating
stapleslstakes In appropriate
locations as shown in the staple
pattern guide.
4, The edges of parallel RECPs must
be stapled with approximately 2" -
5" (5-12.5cm) ovedap depending
on the R,ECPs type,
5. Cansecutive RECPs spliced down
the slope must be end over and
(Shingle style) with an apprexicna.e
3"(7,5cm) overlap. Staple through
overlapped area, approximately
12'(3Dcm) apart across entire
RECPs width.

Construction Specifications
1. Site preparations -Clear, Stub, and strip topsoH from areas under the em-
bankment to remove trees, vegetation, mots, am odder objectionable materiel.
To facilitate sediment cleanout and restoration, clear the pool area of all brush,
trees, and other objectionable materials. Stockpile all topsoil or soil containing
organic matter for use on the outer shell of theembankment to facilitate vegeta-
tive establishment. Phos temporary sedimentcantml measures below the basin
as needed.
2. Cut-off trench -Excavate a cut-off trench along the centerline of the earth
fill embankment Cut the trench to stable soil material, but in no case make it
less than 2 ftdeep. Thecm-off trench mast extend into both abuunents to et least
the elevation of the riser crest Make the minimum bottom width wide enough
to permit operation of excavation and compaction equipment but in no case ie,"
than 2 ft Make side slopes of Ute trench no steeper [hart 1:1. Compaction m-
qukemems are the same as dtose for the embankment Keep the Dench dry
during backfi ing and c-paction operations.
3. Embankment -Take fill material from the approved areas shown on the
plans. It should be clean mineral soil, free of toots, woody vegetation, rocks,
and other objectionable material. Scarify areas on which fill is to be placed
before placing rill. The all material must contain sufficient moisture so it can
be formed by hand into a ball without crumbling. If water can be squeezed out
of the ball, it is too wet for proper compaction. Place fill material in 6 to 8 -inch
continuous the fillarea oral then compact itCom-
paction may be obtained bymming the construction hauling equipment over the
MI so that the entire stufaro of each layer is traversed by at least one wheel or
tread track of the heavy equipment, or a compacta may be used. Construct the
embankment to an elevation if>96 higher than the design height to allow for wt -
tiling.
_._.
4. Skimmer installation -Install floating skimmer as shown in the
section above.
5. Emergency spillway -Install the emergency spillway in undisturbed soii.
The achievement of planned elevations, grade, design width, and entrance and
exit channel slopes are crkiesl to de successful operation of the emergency
6. Inlets-D'echarge water into the basin in a manner to prevent erosion. Use
diversions with outlet protection todivertsediment-laden water tothe upperend
of the pooi area to improve basin trap efficiency (References: RungfComrof
rlfeaswes and Owfer Protection).
7. Erasion control -Construct the structure so the the disturbed area is mi&
mized. Divert surface water away fmm bare areas. Complete the embankment
before dw an is cleared. Stabilize the emergency spiliway embankment and
all other disturbed areas above the crest of the principal spillway bnmedistely

INSTALLATION
1. REFER TO THE PLANS FOR LOCATION, EXTENT, AND SPECIFICATIONS.
IF THERE ARE QUESTIONS OR PROBLEMS WITH THE LOCATION, EXTENT,
OR METHO O
D F INSTALLATION, CONTACT THE ENGINEER, ARCHITECT, OR
RESPONSIBLE PERSONNEL ON THE SITE FOR ASSISTANCE. EROSION
CONTROL PERSONNEL HAVE COPIES OF INSTRUCTIONS AND MAY HAVE
PHOTOGRAPHS OF PROPERLY INSTALLED APRONS AS AN AID TO
INSTALLATION.
IF THE STONE APRON IS NOT INSTALLBD CORRECTLY THE FIRST TIME,
IT WILL HAVE TO BE REBUILT.
2. DETERMINE THE LOCATION ON THE GROUND TAKING INTO
CONSIDERATION:
* DECIDE HOW EQUIPMENT AND MATERIAL WILL REACH THE LOCATION TO
CONSTRUCT THE APRON. DO NOT "PAINT YOURSELF INTO A CORNER" AND
PLACE FILL, STRUCTURES, ETC. THAT COULD BLOCR ACCESS.
* THE LOCATION OF THE APRON MUST BE SOLID GROUND. IT MAY BE
NECESSARY TO EXCAVATE THE LOCATION TO REMOVE MUD AND THEN
HACRFZLL WITH GOOD MATERIAL. THIS IS NECESSARY SO THE STONE
DOES NOT DISAPPEAR INTO THE MUD, WHICH WOULD REQUIRE MUCH MORE
STONE TO COMPLETE THE APRON AND MAKE INSTALLATION DIFFICULT.
3. CLEAR THE LOCATION OF THE APRON. LEAVE AS MUCH OF THE EXISTING
VEGETATION AS POSSIBLE AROUND THE LOCATION TO HOLD THE SOIL ZN
PLACE AND REDUCE THE AREA THAT WILL HAVE TO BE STABILIZED .
AFTERWARD.
4. EXCAVATE THE BOTTOM TO THE REQUIRED DEPTH TO ACCEPT THE STONE
AND THE FILTER BLANKET. WHEN FINISHED, THE BOTTOM OF THE
APRON MUST HE LEVEL WITH THE BOTTOM OF THE CHANNEL; THERE
CANNOT JZ M OVERFALL Al TJj)i END OF THE APRON.
5. PLACE THE FILTER BLANKET, AS SPECIFIED ZN THE PLAN, OVER THE
LOCATION AND UNDER THE LIP OF THE FLARED END SECTION.
6. PLACE THE SPECIFIED STONE TO THE REQUIRED DIMENSIONS AND SHAPE
IT TO THE CONFIGURATION SHOWN IN THE PLAN.
7. STABILIZE THE AREA AROUND THE APRON THAT WAS DISTURBED DURING
CONSTRUCTION. USE ADDITIONAL STONE OR VEGETATION, WHICHEVER IS
APPROPRIATE FOR THE SITUATION.
Planning 11 is important that diversions are properly designed, constructed and
maintained since thev_ concentrate water flow and Increase erosion
potentialCOn51dE"a1lDiS
(Figure 6.20a). Particular care must he taken in planning diversion grades.
Too much slope can result in erosive velocity in the diversion channel or at the
outlet. A change of lv1� from sleeper grade flatter may cause deposition to
occur. The deposition reduces carrying capacity, and may cause overtopping
and failure. Frequent inspection and timely maintenance arc essential to the
proper functioning of diversions.
Sufficient area must be available to construct and properly maintain diversions.
It is usually less costly to excavate a channel and form a ridge or dike on the

Figure 6.20b Temporary gravel diversion dike for vshide crossing (modfied from Va SWO0).
Plan temporay diversions to function 1 year or more, or they may be
constructed anew at the end of each day's grading operation to protect new fill.
Diversions that ate to serve longer than 30 working days should be seeded and
mulched as soon as they are constructed to preserve dike height and reduce
maintenance.
Where design velocities exceed 2 £t/sec. a channel liner is usually necessan to
prevent erosion (Table 8.05a. Jppendix 8.05).
Temporary diversions may serve as in-place sediment traps if overexcavated 1
to 2 feet and placed on a nearly flat grade. The dike serves to divert water as
the stage increases. A combination silt fence and channel in which fill from
the channel is used to stabilize the Fence can trap sediment and divert runoff
simultaneously,
Wherever feasible, build and stabilize diversions and outlets before initiating
other land-disturbine activities.

INSTALLATION
DETAIL
1. Prepare soil before installing rolled
erosion control products (RECPs),
including any necessary application of
lime, fertilizer, and seed.
2. Begin at the top of the channel by
anchoring the RECPs in a 6"(15cm)
deep X 6"(15cm) wide trench with
approximately 12"(30cm) of RECPs
extended beyond the up-slope portion
of the trench. Use ShoreMax mat at the
channel/culvert outlet as supplemental
scour protection as needed. Anchor the
RECPs with a row of staples/stakes
approximately 12"(30cm) apart in the
bottom of the trench. Backfill and
compact the trench after stapling. Apply
seed to the compacted soil and fold the
remaining 12"(30cm) portion of RECPs
track over the seed and compacted soil.
Secure RECPs over compacted soil
with a row of staples/stakes spaced -
approximately 12" apart across the -
width of the RECPs.
3. Roll center RECPs in direction of water
flow in bottom of channel. RECPs wilt
unroll with appropriate side against the
soil surface. Ali RECPs must be I
securely fastened to soil surface by
placing staples/stakes in appropriate
locations as shown in the staple pattern
guide.
4. Place consecutive RECPs end -over -end
(Shingle style) with a 4"-6" overlap. Use
a double row of staples staggered 4"
apart and 4" on center to secure
RECPs.
5. Full length edge of RECPs at top of side
slopes must be anchored with a row of
staples/stakes approximately 12"(30cm)
apartin a 6"(15cm) deep X 6"(15cm)
wide trench. Backfill and compact the
trench after stapling.
6. Adjacent RECPs must be overlapped
approximately T-5" (5-12.5cm)
(Depending on RECPs type) and
stapled.
7.In high flow channel applications a
staple check slot is recommended at 30
to 40 foot (9 -12m) intervals. Use a
double row of staples staggered
4"(10cm) apart and 4"(10cm) on center
over entire width of the channel.
6. The terminal end of the RECPs must be
anchored with a row of staples/stakes
approximately 12" (30cm) apart in a
6"(15cm) deep X 6"(15cm) wide trench.
Backfill and compact the trench after
stapling.

Excavate a keyway trench along the center line of the spillway foundation
extending Lip the aides to the height of the dam. The trench should be at
(cast 2 Feet deep and 2 feet wide with l: 1 aide slopes.
4. Clear the pond area below the elevation ❑F the crest of the spillway to
fncilitate sediment cleanout -
5. All cut and fill slopes should he 2:1 or [latter.
6. Ensure that the stnnc (drainagc) section of the embankmenl has a
mininium hottom width of 3 feel and maximum side slopes or L I That extend
to Lhc bottom ofthe spillway section.
7. Construct the
minimum finished stone spillway btiLlom width, as shown
On Lhc plans, with 2;I side slopes extending to rhe top of the over filled
embankment. Keep the thickness of the sides of the spillway outlet structure
at a minimum (if 21 inches. The weir must be level and constructed to
grade to assure design capacity.
8. MRterial used in the stone section shouid he a will -graded mixture ofstone
with a div site of 9 inches (class B 0t'(,9iott control stone is recommended) and
a maximum stone sloe of E4 inches 'Phe stone may be Inaehine placed and the
smallcrStones workedinto the voids ofthelarger stories. The stone should be
hard, angular, and highly weather -resistant.
9. Discharge inlet water into the basin in a manner to prevent erosion, Use
temporary slope drains or diversions wide outlet protection to divert sediment -
laden water to the upper cad of the pool area to improve basin trap efficiency
(RrJercnces: RunoffConrrolMeusurryand t7ulletProfeerlun).
10. Ensure that the stone spitIway outlet section extends downslrearn past the
toe of the embankment until stable oorditionti are =ched and nutlet velocity
Is acceptable For the receiving sircam. Keep the edges of the clone outlet
section flush with the surrounding ground, and shape the center to confine the
outflow stream (Rq&renaes: ONrI011 PITlJ.'L'ri0d),
11, Direct emergency bypass to natural, Stable areas. Locate bypass outlets
so that flow will not damago the embankment.
IE. Stabilize dic xrnbankment and all disturbed atras above (ho sediment pool
and downstL'eam from the trap immediately of ar construction (References:
Sur�acc Slrrbi nation).
13. Shaw the distance from the top of the spillway m the sedimenr cleanout
level (1 12 the design depth) on the plans and mark it in the Bold
14. Install porous baffles as specified in Practice 6.55, Priwzjx Rglflt-.s
Maintenance Inspect temporary sediment traps at least weekly and after each significant (%
inch or greater) rainfall event and repair immediately- Remove sediment, and
restore the trap la its original dimensions whan the sediment has accumulated
to one-halFdte design dcptli nfthc nap, Place the sediment t11at is tnmovcd in
the designated disposal area, and replace the pan of the gravel facing that tv
impait'cd by sudhnent.
Check the Structure for damage from erosion or piping. PCI'iodically chuck the
dcptli of the spillway to ensure it is a lnirt€11111[11 0N.5 foot below the low point
Of the en1hpnkcncT1t. Immediately fill :icy settlement or the cmbankmcnt to
slightly above design grade. Any riprap displaced front the spillway must
be replaced immediately.
After all sediniont-producing areas have heal permanently stabilized, remove
the structure and all unstahlc scdirnclt. Smooth the area to blend with the
adjoining areas, and stabilize properly (Ralferencev: Surface .Srabih orron)-
