POSITIVE DRAINAGE.
DRAINAGE FROM THE STONE PAD TO A
SEDIMENT TRAP OR BASIN OR OTHER
SEDIMENT TRAPPING STRUCTURE.
STABILIZED CONSTRUCTION ENTRANCES SHOULD BE USED AT ALL POINTS WHERE
TRAFFIC WILL BE LEAVING A CONSTRUCTION SITE AND MOVING DIRECTLY ONTO A
PUBLIC ROAD.
2. IMPORTANT CONSIDERATIONS
A. IF WASHING IS USED, PROVISIONS MUST BE MADE TO INTERCEPT THE WASH WATER AND
TRAP THE SEDIMENT BEFORE IT IS CARRIED OFF SITE. WASH DOWN FACILITIES SHALL BE
REQUIRED AS DIRECTED BY SCDHEC AS NEEDED. WASH DOWN AREAS IN GENERAL
MUST BE ESTABLISHED WITH CRUSHED GRAVEL AND DRAIN INTO A SEDIMENT TRAP OR
SEDIMENT BASIN.
B. CONSTRUCTION ENTRANCES SHOULD BE USED IN CONJUNCTION WITH THE
STABILIZATION OF CONSTRUCTION ROADS TO REDUCE THE AMOUNT OF MUD PICKED UP
BY VEHICLES.
3. MATERIAL
A. THE ENTRANCE SHALL CONSIST OF 1-INCH TO 3-INCH D50 STONE AT A MINIMUM DEPTH
OF 6-INCHES.
B. MINIMUM DIMENSIONS OF THE ENTRANCE SHALL BE 24-FEET WIDE BY 100-FEET LONG.
THE DIMENSION MAY BE INCREASED AS NECESSARY TO ACCOMMODATE SITE
CONDITIONS.
C. THE EDGES OF THE ENTRANCE SHALL BE TAPERED OUT TOWARDS THE ROAD TO
PREVENT TRACKING OF MUD AT THE EDGE OF THE ENTRANCE.
4. INSTALLATION
A. REMOVE ALL VEGETATION AND ANY OBJECTIONABLE MATERIAL FROM THE FOUNDATION
AREA.
B. DIVERT ALL SURFACE RUNOFF AND DRAINAGE FROM STONES TO A SEDIMENT TRAP OR
BASIN.
C. INSTALL A NON-WOVEN GEOTEXTILE FABRIC PRIOR TO PLACING STONE.
D. INSTALL A CULVERT PIPE ACROSS THE ENTRANCE WHEN NEEDED TO PROVIDE POSITIVE
DRAINAGE.
5. INSPECTION AND MAINTENANCE
A. STABILIZED ENTRANCE SHALL BE INSPECTED ONCE EVERY CALENDAR WEEK AND AFTER
STORM EVENTS. IF THE PERIODIC INSPECTION OR OTHER INFORMATION INDICATES
THAT A BMP HAS BEEN INAPPROPRIATELY OR INCORRECTLY INSTALLED, THE PERMITTEE
MUST ADDRESS THE NECESSARY REPLACEMENT OR MODIFICATION REQUIRED TO
CORRECT THE BMP WITHIN 48 HOURS OF IDENTIFICATION.
B. RESHAPE THE STONE PAD AS NEEDED FOR DRAINAGE AND RUNOFF CONTROL.
C. WASH OR REPLACE STONES AS NEEDED AND AS DIRECTED BY INSPECTOR. THE STONE
IN THE ENTRANCE SHOULD BE WASHED OR REPLACED WHENEVER THE ENTRANCE FAILS
TO REDUCE MUD BEING CARRIED OFF-SITE BY VEHICLES. FREQUENT WASHING WILL
EXTEND USEFUL LIFE OF STONE.
D. IMMEDIATELY REMOVE MUD AND SEDIMENT TRACKED OR WASHED ONTO PUBLIC ROADS
