PHASING OF GRADING AC IVITIES
THE AMOUNT OF ACTIVE DISTURBED AREA MUST BE LIMITED TO WHAT CAN BE EFFECTIVELY WATERED 4 TIMES PER
DAY BY EITHER SPRINKLERS OR WATER TRUCKS. TYPICAL 2000 GALLON WATER TRUCKS CAN EFFECTIVELY WATER
ABOUT 4 ACRES PER HOUR. THEREFORE AN 8 HR. WORKDAY DIV/DED BY 4 WATER/NGS PER DAY TIMES 4 AC./HR.
= 8 ACRES PER TRUCK. SINCE WATER TRUCKS ARE ALLOWED TO WORK 7 DAYS A WEEK, 24 HOURS A DAY, IN
SOME LOCATIONS, UP TO 24 AC. PER TRUCK MAY BE ACHIEVED THAT WAY, WITH SPECIAL PERMISSION. LARGER
PROJECTS MUST HAVE MORE TRUCKS, MORE HOURS, MORE SPRINKLERS, OR LESS DISTURBED AREA AT ANY ONE
TIME AREAS ALREADY GRADED OR STOCKPILED MUST BE STABILIZED WITH CHEMICALS, HYDROMULCH, OR
VEGETATION, BEFORE ADDITIONAL AREAS CAN BE STRIPPED FOR GRADING. THE PHASING PATTERN BELOW SHALL BE
SHOWN /N THE REFERENCE MAP ON THIS SHEET AT UPPER RIGHT. DRIVING ROUTES THROUGH A PROJECT MUST BE
COUNTED IN ALL PHASES WHERE THEY ARE ONLY TREATED WITH WATER. IT IS BETTER TO TREAT THEM WITH AN
APPROVED "OIL" (LIKE ENV/ROKLEEN) OR SIMILAR NON -CRUSTING DUST PALLIATIVE, TO SAVE WATER.
ASSUME 1 2000 GALLON WATER TRUCK CAN EFFECTIVELY WATER 8 ACRES PER DAY ON NONE HIGH WIND DAYS.
DURING HIGH WIND DAYS, THE NUMBER OF TRUCKS MAY INCREASE DEPENDING ON THE
