CONSTRUCTION SPECIFICATIONS
1. CLEAR, GRUB & STRIP TOPSOIL FROM AREAS UNDER THE EMBANKMENT TO
REMOVE TREES, VEGETATION, ROOTS AND OTHER OBJECTIONABLE MATERIAL
PLACE TEMPORARY SEDIMENT CONTROLS BELOW THE BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS,
WOOD VEGETATION, ORGANIC MATTER AND OTHER OBJECTIONABLE MATERIAL
PLACE THE FILL IN LIFTS NOT TO EXCEED 9INCHES AND MACHINE COMPACT IT.
OVER FILL THE EMBANKMENT 6INCHES 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.
4. PLACE THE BARREL ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL.
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. PLACE A MINIMUM OF 2 FEET OF COMPACTED
BACKFILL OVER THE PIPE SPILLWAY BEFORE CROSSING IT WITH CONSTRUCTION
EQUIPMENT.
5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURER'S INSTRUCTIONS
6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE
FLEXIBLE JOINT AT THE INLET OF THE BARREL PIPE. ATTACHED THE FLEXIBLE
JOINT TO THE BARREL PIPE AND POSITION THE SKIMMER OVER THE EXCAVATED
PIT. ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE
BASIN.
7. INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTEND
POSSIBLE. 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. 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. IF MULTIPLE SECTIONS AREA REQUIRED, THE UPPER SECTION
SHOULD OVERLAP THE LOWER SECTION SO THAT WATER CANNOT FLOW UNDER
THE FABRIC.

8. DISCHARGE WATER INTO THE BASIN 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. 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.
10. INSTALL POROUS BAFFLES AS SPECIFIED.
11. AFTER ALL SEDIMENT PRODUCING AREAS HAVE BEEN STABILIZED, 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 WEEKLY AND AFTER EACH PERIOD OF
SIGNIFICANT RAINFALL. REMOVE SEDIMENT AND RESTORE TRAP TO ITS ORIGINAL
DIMENSIONS WHEN THE SEDIMENT HAS ACCUMULATED TO ONE-HALF THE HEIGHT
OF THE FIRST BAFFLE. EXCAVATE SEDIMENT FROM THE ENTIRE BASIN. MAKE SURE
VEGETATION GROWING IN THE BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE
SKIMMER. PLACE THE SEDIMENT THAT IS REMOVED IN AN AREA WITH SEDIMENT
CONTROLS.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATER
IS FLOWING UNDERNEATH OR AROUND THEM.
UNCLOGGED THE SKIMMER AS NEEDED. CHECK TO MAKE SURE ORIFICE INSIDE OF
THE SKIMMER IS NOT CLOGGED, IF SO, REMOVE THE DEBRIS. IF SKIMMER ARM OR
BARREL IS CLOGGED, REMOVE THE ORIFICE AND CLEAR THE DEBRIS.
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. MAKE ALL
NECESSARY REPAIRS IMMEDIATELY. REMOVE TRASH AND DEBRIS FROM THE
SKIMMER AND POOL AREAS.

3. ROLL THE BLANKETS A. DOWN OR B. HORIZONTALLY ACROSS THE SLOPE. BLANKETS WILL UNROLL WITH APPROPRIATE SIDE
AGAINST THE SOIL SURFACE. ALL BLANKETS MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING STAPLES/STAKES
IN APPROPRIATE LOCATIONS AS SHOWN IN THE STAPLE PATTERN GUIDE. WHEN USING THE DOT SYSTEM' STAPLES/STAKES
SHOULD BE PLACED THROUGH EACH OF THE COLORED DOTS CORRESPONDING TO THE APPROPRIATE STAPLE PATTERN.
4. THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY 2" - 5" (5 CM - 12.5 CM) OVERLAP DEPENDING
ON BLANKET TYPE.
5. CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE PLACED END OVER END (SHINGLE STYLE) WITH AN APPROXIMATE
3" (7.5 CM) OVERLAP. STAPLE THROUGH OVERLAPPED AREA, APPROXIMATELY 12" (30 CM) APART ACROSS ENTIRE
BLANKET WIDTH.
NOTE:
*IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE OR STAKE LENGTHS GREATER THAN 6" (15 CM) MAY BE NECESSARY TO
PROPERLY SECURE THE BLANKETS.
MAINTENANCE:
1. INSPECT THE EROSION CONTROL BLANKET ONCE A WEEK AND AFTER EVERY RAINFALL.
2. IMMEDIATELY REPAIR AND/OR REPLACE ANY DAMAGED BLANKET.
3. IF GROUND COVER IS NOT ESTABLISHED THROUGH THE BLANKET WITHIN 2 WEEKS, THE BLANKET
SHOULD BE REMOVED AND THE AREA RESEEDED. AFTER RESEEDING, THE BLANKET SHOULD BE
