"TRACKING" WITH MACHINERY UP AND DOWN
THE SLOPE PROVIDES GROOVES THAT WILL
CATCH SEED, RAINFALL AND REDUCE RUNOFF.
TRACKING
1.CONDITIONS OF USE
1.1.ALL SLOPES STEEPER THAN 3H:1V AND GREATER THAN 5 VERTICAL FEET REQUIRE SURFACE ROUGHENING TO A DEPTH OF 2 TO 4 INCHES PRIOR TO SEEDING.
1.2.AREAS THAT WILL NOT BE STABILIZED IMMEDIATELY MAY BE ROUGHENED TO REDUCE RUNOFF VELOCITY UNTIL SEEDING TAKES PLACE.
1.3.SLOPES WITH A STABLE ROCK FACE DO NOT REQUIRE ROUGHENING.
1.4.SLOPES WHERE MOWING IS PLANNED SHOULD NOT BE EXCESSIVELY ROUGHENED.
2.DESIGN AND INSTALLATION SPECIFICATIONS
2.1.DISTURBED AREAS THAT WILL NOT REQUIRE MOWING MAY BE STAIR-STEP GRADED, GROOVED, OR LEFT ROUGH AFTER FILLING.
2.2.STAIR STEP GRADING IS PARTICULARLY APPROPRIATE IN SOILS CONTAINING LARGE AMOUNTS OF SOFT ROCK. STAIR SHOULD BE WIDE ENOUGH TO WORK WITH
STANDARD EARTH MOVING EQUIPMENT. STAIRS STEPS MUST BE ON CONTOURS OR GULLIES WILL FORM ON THE SLOPE.
2.3.AREAS THAT WILL BE MOWED, MAY HAVE SMALL FURROWS LEFT BY DISKING, HARROWING, RAKING, OR SEED-PLANTING MACHINERY OPERATED ON THE CONTOUR.
2.4.GRADED AREAS WITH SLOPES GREATER THAN 3H:1V BUT LESS THAN 2H:1V SHOULD BE ROUGHENED BEFORE SEEDING BY TRACKING.
2.5.TRACKING IS DONE BY OPERATING EQUIPMENT UP AND DOWN THE SLOPE TO LEAVE HORIZONTAL DEPRESSIONS IN THE SOIL.
3.MAINTENANCE STANDARDS
3.1.PERIODICALLY CHECK ROUGHENED, SEEDED, PLANTED AND MULCHED SLOPES FOR RILLS AND GULLIES, PARTICULARLY AFTER A SIGNIFICANT STORM EVENT. FILL
THESE AREAS SLIGHTLY ABOVE THE ORIGINAL GRADE, THEN RE-SEED AND MULCH AS SOON AS POSSIBLE.
