CONSTRUCTION SEQUENCE:
1. UNIFORMLY GRADE A SHALLOW DEPRESSION APPROACHING THE INLET.
2. DRIVE 5' STEEL POST 2' INTO THE GROUND SURROUNDING THE INLET.
SPACE POST EVENLY AROUND THE PERIMETER OF THE INLET, A MAXIMUM
OF 4' APART.
3. SURROUND THE POST WITH WIRE MESH HARDWARE CLOTH. SECURE THE
WIRE MESH TO THE STEEL POST AT THE TOP, MIDDLE AND BOTTOM.
PLACING A 2' FLAP OF THE WIRE MESH UNDER THE GRAVEL FOR
ANCHORING IS RECOMMENDED.
4. PLACE CLEAN GRAVEL (NCDOT #5 OR #57 STONE) ON A 2:1 SLOPE
WITH A HEIGHT OF 16' TO 18" AROUND THE WIRE, AND SMOOTH TO AN
EVEN GRADE.
5. ONCE THE CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE
ACCUMULATED SEDIMENT, AND ESTABLISH FINAL GRADING ELEVATIONS.
6. COMPACT THE AREA PROPERLY AND STABILIZE IT WITH GROUNDCOVER.
MAINTENANCE:
INSPECT INLETS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2 INCH
OR GREATER) RAINFALL EVENT. CLEAR THE MESH WIRE OF ANY DEBRIS OR
OTHER OBJECTS TO PROVIDE ADEQUATE FLOW FOR SUBSEQUENT RAINS.
TAKE CARE NOT TO DAMAGE OR UNDERCUT THE WIRE MESH DURING
SEDIMENT REMOVAL. REPLACE STONE AS NEEDED.
TEMPORARY/PERMANENT
GRASS SPECIFICATION
1. CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3 INCHES DEEP OVER
ADVERSE SOIL CONOf K)NS.
2. RIP THE ENTIRE AREA TO A 6 INCH DEPTH.
3. REMOVE ALL ROCKS, ROOTS AND OTHER OBSTRUCTIONS LEAVING SURFACES
SMOOTH AND UNIFORM.
4. APPLY AGRICULTURAL LIME AND FERTILIZER UNIFORMLY AND MIX WITH SOIL
LIME 45 LDS. PER 1000 S.F.
PHOSPHOROUS: 20 LOS PER 1000 S.F.
FERTILIZER: 17 LBS. PER 1000 S.F.
5. CONTINUE TILLAGE UNTIL A WELL PULVERIZED, FIRM, UNIFORM SEED BED IS
PREPARED 4-6 INCHES DEEP.
6. SEED ON A FRESHLY PREPARED SEED BED AND COVER SEED LIGHTLY.
2 - 3 LISS PER 1000 S.F. (SEE MIXTURE BELOW)
7. MULCH IMMEDIATELY AFTER SEEDING AND ANCHOR MULCH.
GRAIN STRAW & HAY AT 75 TO 100 LOS PER 1000 S.F.
WOOD CHIPS AT 500 LBS. PER 1000 S.F.
JUTE &MESH AS PER MANUFACTURER
8. ASPHALT FOR ANCHORING MULCH SHALL BE TYPE SS-1 EMULSION AND
APPLIED AT A RATE OF 1000 GAL. PER ACRE FOR SLOPE STABILIZATION,
AND 150 GAL. PER TON OF STRAW FOR ANCHORING STRAW.
9. INSPECT ALL SEEDED AREAS AND MAKE NECESSARY REPAIRS OR RESEED
WITHIN THE PLANTING SEASON, IF POSSIBLE. IF GRASS STAND SHOULD BE
OVER 60% DAMAGED, REESTABLISH FOLLOWING ORK,YNAL LIME, FERTILIZER
AND SEEDING RATES.
10. CONSULT CONSERVATION INSPECTOR ON MAINTENANCE, TREATMENT, AND
FERTILIZATION AFTER PERMANENT COVER IS ESTABLISHED.
11. SEED FOR TEMPORARY AND PERMANENT APPLICATIONS SHALL BE:
20% CARPET GRASS
24% BERMUDA GRASS
20% TURF FESCUE 10% CREEPING RED FESCUE
24% ANNUAL RYE GRAIN
•BERMUDA SEED SHALL BE HULLED FOR WARM WEATHER
PLANTING. PURITY OF SEED SHALL BE A MIN. OF 98% AND
GERMINATION SHALL BE A MIN. OF 85%.
ALL DISTURBED AREA SHALL BE SEEDED WITHIN 15 DAYS OF THE COMPLETION OF
GRADING. CONSULT CONSERVATION ENGINEER OR SOIL CONSERVATION SERVICE FOR
ADDITIONAL INFORMATION CONCERNING OTHER ALTERNATIVES FOR VEGETATION OF

Skimmer shown in
floating position
1. Skimmer can be attached to a straight 4" sch 40 pipe through the dam but the pipe may need
to be anchored to the bottom at the connection so it is secure. Coupling can be removed and
hose attached to outlet using the threaded 1W fitting. Typical methods used: on a metal
structure a steel stubout welded on the side at the bottom side with a 1 W threaded Coupling or
reducers; on a concrete structure with a hole or orifice at the bottom, use a steel plate with a
hole cut in it and coupling welded to it that will fit over the hole in the concrete and bolted to the
structure with sealant; grout a 4' pvc pipe in a hole in the concrete to connect the skimmer.
2. Dimensions are approximate, not intended as plans for construction.
3. Barrel (solid, not foam core pipe) should be 1.4 times the depth of water with a maximum
length of 8' so the inlet can be pulled to the side for maintenance. Skimmer is made for small
sediment °traps" with a maximum depth of 4'.
4. Inlet is 3" pipe between the straps with aluminum screen door for access to the 1W inlet and
orifice inside.
5. Capacity 1,728 cubic feet per day maximum with 1W inlet and 1'A" head. Inlet can be
reduced by installing a smaller orifice using the plug and cutter provided to adjust flow rate for
the particular basin volume and drawdown time required.
6. Shipped assembled. User glues inlet extension and barrel, installs vent, cuts orifice in plug
and attaches to outlet pipe or structure. Includes flexible hose, rope, orifice cutter, etc.
2. INSTALL TOPSOIL ON SIDE SLOPES ABOVE NORMAL POOL AND SEED WITH A MIX OF
2OX CARPET GRASS, 24% BERMURk 20% FESCUE, 1OX CREEPING RED FESCUE, AND
24X RYE. SEED AT A RATE OF 2-3 POUNDS PER 1000 SF.
3. VEGETATED SHELF: THE CONTRACTOR SHALL INSTALL EQUAL NUMBERS OF THE LISTED
SUITABLE SPECIES. GROOUP SIMILAR SPECIES OF PLANTS TOGETHER (APPROX. 10-15
PLANTS PER GROUP). NO PLANTS SHALL BE PLANTED WITHIN 10 FEET OF THE OUTLET
STRUCTURE.
4. BOTTOM HALF OF VEGETATED SHELF SHALL BE PLANTED WITH SHALLOW WATER PLANT
SPECIES, SEE TABLE.
5. TOP HALF OF VEGETATED SHELF SHALL BE PLANTED WITH SHALLOW LAND PLANT
SPECIES, SEE TABLE.
6. THE VEGETATED SHELF SHALL BE PLANTED WITH PLUGS OR POTS (MIN. 2 CU IN) AT
24"-36" O.C. IN A CHECKERBOARD PATTERN. A MINIMUM OF 50 PLANTS PER 200 SF
OF SHELF AREA SHALL BE PLANTED.
