WILL NOT POND WATER, AND IMMEDIATELY STABILIZE.
12. EROSION CONTROLS SHALL REMAIN IN PLACE UNTIL SITE HAS BECOME STABILIZED.
ANY REMOVAL OF EROSION CONTROL MEASURES MUST BE APPROVED BY THE SITE
INSPECTOR PRIOR. DO NOT REMOVE TEMPORARY SEDIMENT TRAPS UNTIL THE

C5.0-05.1). CONSTRUCTION VEHICLES SHALL AVOID TRAVELING ON THESE AREAS.
3. BEGIN BULK GRADING OPERATIONS WHILE ONLY EXCAVATING TO THE REQUIRED FIELD SUB -GRADE AND TOP OF TRENCH ELEVATION. THE FIELD SUBGRADE
