THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY 2" - 5" (5 CM - 12.5 CM) OVERLAP DEPENDING ON BLANKET TYPE. 5. CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE PLACED END OVER END (SHINGLE STYLE) WITH AN APPROXIMATE 3" (7.5 CM) OVERLAP. STAPLE THROUGH OVERLAPPED AREA, APPROXIMATELY 12" (30 CM) APART ACROSS ENTIRE BLANKET WIDTH. NOTE: *IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE OR STAKE LENGTHS GREATER THAN 6" (15 CM) MAY BE NECESSARY TO PROPERLY SECURE THE BLANKETS. MAINTENANCE: 1. INSPECT THE EROSION CONTROL BLANKET ONCE A WEEK AND AFTER EVERY RAINFALL. 2. IMMEDIATELY REPAIR AND/OR REPLACE ANY DAMAGED BLANKET. 3. IF GROUND COVER IS NOT ESTABLISHED THROUGH THE BLANKET WITHIN 2 WEEKS, THE BLANKET SHOULD BE REMOVED AND THE AREA RESEEDED. AFTER RESEEDING, THE BLANKET SHOULD BE REINSTALLED.

VEGITATE THE RIDGE OF THE BERM IMMEDIATELY AFTER CONSTRUCTION UNLESS THE BERM WILL REMAIN IN PLACE FOR LESS THAN 30 DAYS. MAINTENANCE: INSPECT TEMPORARY DIVERSIONS ONCE A WEEK AND AFTER EVERY RAINFALL. IMMEDIATELY REMOVE SEDIMENT FROM THE FLOW AREA AND REPAIR THE DIVERSION RIDGE.
