SLOPE
NOTES: INSTALLATION
1. PREPARE SOIL BEFORE INSTALLING EROSION CONTROL BLANKETS (ECB's),
INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND SEED.
2. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE ECB's IN ACCORDANCE
WITH THE MANUFACTURER'S RECOMMENDATIONS. APPLY SEED TO COMPACTED
SOIL AND FOLD REMAINING PORTION OF ECB's BACK OVER SEED AND
COMPACTED SOIL. SECURE ECB's OVER COMPACTED SOIL WITH A ROW OF
STAKES/STAPLES SPACED ACCORDANCE TO THE MANUFACTURER'S
RECOMMENDATIONS ACROSS THE WIDTH OF THE ECB's.
3. ROLL THE ECB's DOWN,(A) OR HORIZONTALLY (B) ACROSS THE SLOPE.
ECB's WILL UNROLL WITH APPROPRIATE SIDE AGAINST THE SOIL SURFACE.
ALL ECB's MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING
STAKES/STAPLES IN APPROPRIATE LOCATIONS AS SHOWN ON THE
STAKE/STAPLE PATTERN GUIDE.
4. THE EDGES OF PARALLEL ECB's MUST BE STAKED/STAPLED WITH OVERLAP
DEPENDING ON ECB's TYPE. SEE THE MANUFACTURER'S RECOMMENDATIONS.
5. CONSECUTIVE ECB's SPLICED DOWN THE SLOPE MUST BE PLACED END OVER
END (SHINGLE STYLE) WITH AN OVERLAP (SEE THE MANUFACTURER'S
RECOMMENDATIONS). STAKE/STAPLE THROUGH OVERLAPPED AREA, ACROSS
ENTIRE ECB's WIDTH PER MANUFACTURER'S RECOMMENDATIONS.
6. IN LOOSE SOIL CONDITIONS, THE USE OF STAKE OR STAPLE LENGTHS
GREATER THAN 6" MAY BE NECESSARY TO PROPERLY SECURE THE ECB's.
7. THE CONTRACTOR SHALL FOLLOW ALL INSTALLATION INSTRUCTIONS AS
RECOMMENDED BY THE MANUFACTURER.
