NOTES
1. CONDITION OF USE
1.1. ALL SLOPES STEEPER THAN 3:1 AND GREATER THAN 5 VERTICAL FEET REQUIRE SURFACE ROUGHENING..
1.2. AREAS WITH GRADES STEEPER THAN 3:1 SHOULD BE ROUGHENED TO A DEPTH OF 2 TO 4 INCHES PRIOR TO SEEDING.
1.3. AREAS THAT WILL NOT BE STABILIZED IMMEDIATELY MAY BE ROUGHENED TO REDUCE RUNOFF VELOCITY UNTIL SEEDING TAKES PLACE.
1.4. SLOPES WITH A STABLE ROCK FACE DO NOT REQUIRE ROUGHENING.
1.5. SLOPES WHERE MOWING IS PLANNED SHOULD NO BE EXCESSIVELY ROUGHENED.
2. DESIGN AND INSTALLATION SPECIFICATIONS
2.1. DISTURBANCE AREAS THAT WILL NOT REQUIRE MOWING MAY BE STAIR-STEO 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 MOST 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, RANKING, OR SEED -PLANTING MACHINERY
OPERATED ON THE CONTOUR.
2.4. GRADED AREAS WITH SLOPES GRATER THAN 3:1 BUT LESS THAN 2:1 SHOULD BE ROUGHED BEFORE SEEDING.
3. MAINTENANCE STANDARDS
3.1. PERIODICALLY CHECK ROUGHENED, SEEDED, PLANTED AND MULCHED SLOPES FOR RILLS AND GULLIES, PARTICULARLY AFTER A SIGNIFICANT
STORM EVENT. FILL THIS AREAS SLIGHTLY ABOVE THE ORIGINAL GRADE, THEN RE -SEED AND MULCH AS SOON AS POSSIBLE.
