2.2. STANDARD STRENGTH FABRIC REQUIRES WIRE BACKING TO INCREASE THE STRENGTH OF THE FENCE WIRE BACKING OR CLOSER POST SPACING MAY BE REQUIRED
FOR EXTRA STRENGTH FABRIC IF FIELD PERFORMANCE WARRANTS A STRONGER FENCE.
2.3. WHERE THE FENCE IS INSTALLED. THE SLOPE SHALL NOT BE STEEPER THAN ZH:1V
2.4 IF A TYPICAL SILT FENCE IS USED, THE STANDARD 4'X4- TRENCH MAY BE REDUCED AS LONG AS THE BOTTOM 8 INCHES OF THE SILT FENCE FABRIC IS WELL BURIED AND
SECURE IN A TRENCH THAT STABILIZES THE FENCE AND DOES NOT ALLOW WATER TO BYPASS OR UNDERMINE THE SILT FENCE
2.5. FILTER FABRIC FENCES SHALL BE INSTALLED ALONG CONTOURS WHENEVER POSSIBLE
3. MAINTENANCE STANDARDS
3,1. ANY DAMAGE SHALL BE REPAIRED IMMEDIATELY
32. IF CONCENTRATED FLOWS ARE EVIDENT UPHILL OF THE FENCE. THEY MUST BE INTERCEPTED AND CONVEYED TO A SEDIMENT TRAP OR POND.
3.3. IT IS IMPORTANT TO CHECK THE UPHILL SIDE OF THE FENCE FOR SIGNS OF THE FENCE CLOGGING AND ACTING AS A BARRIER TO FLOW AND THEN CAUSING
CHANNELIZATION OF FLOWS PARALLEL TO THE FENCE IF THIS OCCURS, REPLACE THE FENCE OR REMOVE THE TRAPPED SEDIMENT
3.4, SEDIMENT MUST BE REMOVED WHEN SEDIMENT IS 6 INCHES HIGH

1. DRIVEWAYS SHALL BE PAVED TO

NOTES:
1. CONDITION OF USE
1.1. CONSTRUCTION ENTRANCE SHALL BE STABILIZED WHEREVER TRAFFIC WILL BE LEAVING A CONSTRUCTION SITE AND TRAVELING ON PAVED ROADS OR OTHER
PAVED AREAS WITHIN 1.000 FEET OF THE SITE
1.2, FOR RESIDENTIAL CONSTRUCTION PROVIDE STABILIZED CONSTRUCTION ENTRANCES FOR EACH RESIDENCE IN ADDITION TO THE MAIN SUBDIVISION
ENTRANCE, STABILIZED SURFACES SHALL BE OF SUFFICIENT LENGTRWIDTH TO PROVIDE VEHICLE ACCESSIPARKING, BASED ON LOT SIZEICONFIGURATION.
2. DESIGN AND WSTALLATION SPECIFICATIONS
2.1 A SEPARATION GEOTEXTILE SHALL BE PLACED UNDER THE SPALLS TO PREVENT FINE SEDIMENT FROM PUMPING UP INTO THE ROCK PAD. THE GEOTEXTILE
SHALL MEET THE FOLLOWING STANDARDS"
GRAB TENSILE STRENGTH (ASTM D4632)
200 LBS. MIN
GRAB TENSILE ELONGATION (ASTM D4632)
30 % MAX, (WOVEN)
CBR PUNCTURE STRENGTH (ASTM D62411
495 LBS. MIN
ADS (ASTM D4751)
26-45 (U.S- STANDARD SIEVE SEE)
2.2. DO NOT USE CRUSHED CONCRETE, CEMENT, OR CALCIUM CHLORIDE FOR CONSTRUCTION ENTRANCE STABILIZATION BECAUSE THESE PRODUCTS RAISE PH
LEVELS IN STORMWATER AND CONCRETE DISCHARGE TO SURFACE WATERS OF THE STATE IS PROHIBITED.
2.3. HOG FUEL (WOOD BASED MULCH) MAY BE SUBSTITUTED FOR OR COMBINED WITH QUARRY SPALLS IN AREAS THAT WILL NOT BE USED FOR PERMANENT ROADS.
HOG FUEL IS NOT RECOMMENDED FOR ENTRANCE STABILIZATION IN URBAN AREAS. THE INSPECTOR MAY AT ANY TIME REQUIRE THE USE OF QUARRY $PALLS
IF THE HOG FUEL IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT OR IF THE HOG FUEL IS BEING CARRIED ONTO PAVEMENT
2.4, FENCING SHALL BE INSTALLED AS NECESSARY TO RESTRICT TRAFFIC TO THE CONSTRUCTION ENTRANCE.
2.5. WHENEVER POSSIBLE, THE ENTRANCE SHALL BE CONSTRUCTED ON A FIRM. COMPACTED SUBGRADE. THIS CAN SUBSTANTIALLY INCREASE THE
EFFECTIVENESS OF THE PAD AND REDUCE THE NEED FOR MAINTENANCE.
3. MAINTENANCE STANDARDS
3.1, OUARRY SPALLS SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS
3.2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF
SEDIMENT SHALL BE USED THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL
WASH IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND
3.3. ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED IMMEDIATELY BY SWEEPING THE SEDIMENT COLLECTED BY SWEEPING SHALL BE
REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DOWN THE STREET, EXCEPT WHEN SWEEPING IS INEFFECTIVE AND
THERE IS A THREAT TO PUBLIC SAFETY. IF R IS NECESSARY TO WASH THE STREETS, A SMALL SUMP MUST BE CONSTRUCTED. THE SEDIMENT WOULD THEN BE
WASHED INTO THE SUMP WHERE IT CAN BE CONTROLLED AND DISCHARGED APPROPRIATELY- WASH WATER MUST BE PUMPED BACK ONTO THE SITE AND
CANNOT DISCHARGE TO SYSTEMS TRIBUTARY TO SURFACE WATERS.
3.4. ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY,
3,5. IF VEHICLES ARE ENTERING OR EXITING THE SITES AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S). FENCING SHALL BE INSTALLED TO CONTROL
TRAFFIC.
