NOTES:
CLEAR AND EXCAVATE THE AREA OF THE STONE DITCH WHILE PROTECTING AND MAINTAINING
SUBGRADE INFILTRATION RATES FOLLOWING THESE STEPS:
1.EXCAVATE IN DRY SUBGRADE CONDITIONS AND AVOID EXCAVATING IMMEDIATELY AFTER
STORMS WITHOUT A SUFFICIENT DRYING PERIOD.
2.DO NOT ALLOW EQUIPMENT TO CROSS THE STONE DITCH AREA AFTER EXCAVATION HAS
BEGUN. OPERATE EXCAVATION EQUIPMENT FROM OUTSIDE THE STONE DITCH AREA OR
FROM UNEXCAVATED PORTIONS OF THE AREA USING AN EXCAVATION STAGING PLAN.
3.USE EQUIPMENT WITH TRACKS RATHER THAN TIRES TO MINIMIZE SOIL COMPACTION WHEN
EQUIPMENT ON THE SUBGRADE SURFACE IS UNAVOIDABLE.
4.DIG THE FINAL 9 TO 12 INCHES BY USING THE TEETH OF THE EXCAVATOR BUCKET TO
LOOSEN SOIL AND DO NOT SMEAR THE SUBGRADE SOIL SURFACE. FINAL GRADING OR
SMOOTHING OF THE SUBGRADE SHOULD BE DONE BY HAND IF POSSIBLE.
5.MINIMIZE THE TIME BETWEEN EXCAVATION AND PLACEMENT OF THE SAND AND STONE
AGGREGATE.
THE FINAL SUBGRADE SLOPE SHALL NOT EXCEED 0.5%. THE SLOPE OF THE SUBGRADE SHALL
BE CHECKED BEFORE PROCEEDING. WHERE POSSIBLE, EXCAVATE SOIL FROM THE SIDES OF
THE STONE DITCH AREA TO MINIMIZE SUBGRADE COMPACTION FROM EQUIPMENT. AFTER
VERIFYING THE SUBGRADE SLOPE, SCARIFY THE SOIL SUBGRADE SURFACE APPROXIMATE 2
INCH DEPTH TO MAINTAIN THE SOIL'S PRE-DISTURBANCE INFILTRATION RATE AND POSSIBLY
IMPROVE THE SOIL'S INFILTRATION RATE. SCARIFYING THE SUBGRADE MUST OCCUR WHILE
THE SOIL IS DRY. TO SCARIFY THE SUBGRADE, USE BACKHOE BUCKET'S TEETH TO RAKE THE
SURFACE OF THE SUBGRADE .
