SILT FENCES.
A SILT FENCE IS A TEMPORARY SEDIMENT BARRIER CONSISTING OF FILTER FABRIC STRETCHED
ACROSS AND ATTACHED TO SUPPORTING POSTS, ENTRENCHED, AND, DEPENDING UPON THE
STRENGTH OF THE FABRICATED, SUPPORTED WITH WIRE FENCE. SILT FENCES MAY BE USED
FOR PERIMETER CONTROL, PLACED UPSTREAM OF THE POINT(S) OF THE DISCHARGE OF
SHEET FLOW FROM A SITE. THEY MAY ALSO BE USED AS INTERIOR CONTROLS BELOW
DISTURBED AREAS WHERE RUNOFF MAY OCCUR IN THE FORM OF SHEET AND RILL EROSION,
AND PERPENDICULAR TO MINOR SWALES OR DITCH LINES THAT DRAIN UP TO ONE ACRE.
SILT FENCES ARE GENERALLY INEFFECTIVE IN LOCATIONS WHERE THE FLOW IS CONCENTRATED
AND ARE ONLY APPLICABLE FOR SHEET OR OVERLAND FLOWS.
STABILIZATION OF VEHICLE TRAFFIC AREAS. ALL AREAS OF SIGNIFICANT VEHICLE TRAFFIC (SITE
ENTRANCES, ACCESS ROADS, PARKING LOTS, ETC.) SHOULD BE STABILIZED IMMEDIATELY AFTER
GRADING TO PREVENT EROSION CONTROL DUST. SITE ENTRANCES AND EXISTS ARE ESPECIALLY
IMPORTANT. USE GRAVEL APPROACHES TO LIMIT TRACKING OF SEDIMENT OFFSITE.

EROSION CONTROL NOTES
1. ALL BUILDING PADS ARE TO BE DIKED AND THE DIKES MAINTAINED TO PREVENT
WATER FROM FLOWING FROM THE PAD UNTIL THE STREETS AND DRIVEWAYS ARE
PAVED AND WATER CAN FLOW FROM THE PADS WITHOUT CAUSING EROSION, OR
CONSTRUCT DRAINAGE FACILITIES TO THE SATISFACTION OF THE COUNTY Vj
DEPARTMENT OF PUBLIC WORKS THAT WILL ALLOW WATER TO DRAIN FROM THE PAD
WITHOUT CAUSING EROSION.
2. TOPS OF ALL SLOPES TO BE DIKED OR TRENCHED TO PREVENT WATER FROM
FLOWING OVER THE CREST OF SLOPES.
3. MANUFACTURED SLOPES AND PADS SHALL BE ROUNDED VERTICALLY AND
HORIZONTALLY AS APPROPRIATE TO BLEND WITH THE SURROUNDING TOPOGRAPHY.
4, AS SOON AS CUTS OR EMBANKMENTS ARE COMPLETED, BUT NOT LATER THAN
OCTOBER 1 ALL CUT AND FILL SLOPES SHALL BE STABILIZED WITH A HYDROMULCH
MIXTURE OR AN EQUAL TREATMENT APPROVED BY THE COUNTY DEPARTMENT OF
PUBLIC WORKS. BETWEEN OCTOBER 1 AND APRIL 30, APPROVED SLOPE PROTECTION
MEASURES SHALL PROCEED IMMEDIATELY BEHIND THE EXPOSURE OF CUT SLOPES
AND /OR THE CREATION OF EMBANKMENT SLOPES.
5. CATCH BASINS, DESILTING BASINS AND STORM DRAIN SYSTEM SHALL BE INSTALLED
TO THE SATISFACTION OF THE COUNTY DEPARTMENT OF PUBLIC WORKS.
6, GRAVEL BAG CHECK DAMS ARE TO BE PLACED IN A MANNER APPROVED BY THE
COUNTY DEPARTMENT OF PUBLIC WORKS IN UNPAVED STREETS WITH GRADIENTS
IN EXCESS OF 2% AND ON OR IN OTHER GRADED OR EXCAVATED AREAS AS
REQUIRED BY THE COUNTY DEPARTMENT OF PUBLIC WORKS.
7, THE DEVELOPER TO MAINTAIN THE PLANTING AND EROSION CONTROL MEASURES
DESCRIBED ABOVE UNTIL RELIEVED OF SAME BY THE COUNTY DEPARTMENT OF
PUBLIC WORKS. THE DEVELOPER TO REMOVE ALL SOIL INTERCEPTED BY THE
GRAVEL BAGS, CATCH BASINS AND DESILTING BASINS AND KEEP THESE FACILITIES

AS DIRECTED BY THE COUNTY DEPARTMENT OF PUBLIC WORKS.
SILTATION AND SEDIMENT CONTROL MEASURES NOTES
1, THE SEDIMENT BASINS SHALL BE PROVIDED AT THE LOWER END OF EVERY
DRAINAGE AREA PRODUCING SEDIMENT RUNOFF. THE BASINS SHALL BE MAINTAINED
AND CLEANED TO DESIGN CONTOURS AFTER EVERY RUNOFF PRODUCING STORM.
THE BASINS SHOULD BE SEMI - PERMANENT STRUCTURES THAT WOULD REMAIN
UNTIL SOIL STABILIZING VEGETATION HAS BECOME WELL ESTABLISHED ON ALL
ERODIBLE SLOPES.
2• SEDIMENTATION BASINS MAY NOT BE REMOVED OR MADE INOPERATIVE WITHOUT
PRIOR APPROVAL OF THE COUNTY ENGINEER.
3. UTILITY TRENCHES THAT ARE CUT THROUGH BASIN DIKES OR BASIN INLET DIKES
SHALL BE PLUGGED WITH GRAVEL BAGS FROM TOP OF PIPE TO TOP OF DIKE.
4. ALL UTILITY TRENCHES SHALL BE BLOCKED AT THE PRESCRIBED INTERVALS WITH
A DOUBLE ROW OF GRAVEL BAGS WITH A TOP ELEVATION THAT IS TWO GRAVEL
BAGS BELOW, THE GRADED SURFACE OF THE STREET. GRAVEL BAGS ARE TO
BE PLACED WITH LAPPED COURSES. THE INTERVALS PRESCRIBED BETWEEN GRAVEL
BAG BLOCKING SHALL DEPEND ON THE SLOPE OF THE GROUND SURFACE BUT SHALL
NOT EXCEED THE FOLLOWING:
GRADE OF THE STREET INTERVAL
LESS THAN 2% 200 FEET MAXIMUM

WATER IN THE TRENCH AREA. CARE SHOULD BE EXERCISED TO PROVIDE FOR
CROSS FLOW AT FREQUENT INTERVALS WHERE TRENCHES ARE NOT ON THE
CENTERLINE OF A CROWNED STREET.
6. ALL BUILDING PADS SHOULD BE SLOPED TOWARDS THE DRIVEWAYS AND VELOCITY
CHECK DAMS PROVIDED AT THE BASE OF ALL DRIVEWAYS DRAINING INTO THE STREET

8. PROVIDE VELOCITY CHECK DAMS IN ALL PAVED STREET AREAS ACCORDING TO
INTERVALS INDICATED BELOW. VELOCITY CHECK DAMS MAY BE CONSTRUCTED OF
GRAVEL BAGS, TIMBER, OR EROSION RESISTANT MATERIALS APPROVED BY THE
COUNTY ENGINEER. AND SHALL EXTEND COMPLETELY ACROSS THE STREET CHANNEL
AT RIGHT ANGLES TO THE CENTERLINE. VELOCITY CHECK DAMS MAY ALSO SERVE AS
SEDIMENT TRAPS.
GRADE TO STREET INTERVAL NUMBER OF
LESS THAN 2.0% AS REQUIRED BAGS HIGH =1 M
2 % -4% 100 FEET 1 R
4% -6% 50 FEET 1
6% -10% 50 FEET 2 Owl%

9. PROVIDE A GRAVEL BAG SILT BASIN OR TRAP BY EVERY STORM DRAIN INLET TO v
PREVENT SEDIMENT FROM ENTERING DRAIN SYSTEM.
10. GRAVEL BAGS AND FILL MATERIAL SHALL BE STOCKPILED AT INTERVALS, READY FORT►
USE WHEN REQUIRED.
11. ALL EROSION CONTROL DEVICES WITHIN THE DEVELPOMENT SHOULD BE MAINTAINED
DURING AND AFTER EVERY RUNOFF- PRODUCING STORM, IF POSSIBLE MAINTENANCS z
CREWS WOULD BE REQUIRED TO HAVE ACCESS TO ALL AREAS.
12. PROVIDE ROCK RIPRAP ON CURVES AND STEEP DROPS IN ALL EROSION PRONE
DRAINAGE CHANELS DOWNSTREAM FROM THE DEVELOPMENT. THIS PROTECTION WOULD
REDUCE EROSION CAUSED BY INCREASED FLOWS THAT MAY BE ANTICIPATED FROM
DENUDED SLOPES, OR FROM IMPERVIOUS SURFACES.
13. ANY PROPOSED ALTERNATE CONTROL MEASURES MUST BE APPROVED IN ADVANCE
BY ALL RESPONSIBLE AGENCIES: i.e. COUNTY ENGINEER, DEPARTMENT OF SANITATION
