EROSION CONTROL NOTES:
1. ALL AREAS DISTURBED AND LEFT FOR MORE THAN.,dG_0AYS_. MUST BE SEEDED AND
MULCHED UNLESS OTHERWISE NOTED, CONTRACTOR MUST MAINTAIN NEWLY GRADED
AREAS AND REPAIR AREAS WHERE SETTLING AND EROSION HAVE! OCCURRED.
2. CONTRACTOR MUST PROVIDE ALL MATERIALS AND TAKE WHATEVER MEANS NECESSARY
70 PREVENT THE EROSION OF AND DEPOSIT OF SEDIMENT ON ADJACENT AND
DOWNSTREAM PROPERTIES. CONTRACTOR MUST IMPLEMENT AND PROVIDE SUITABLE
EROSION CONTROL MEASURES (LE, SEDIMENTATION BARRIERS, HAYBALES,
SILTATION CURTAINS, TEMPORARY DETENTION DISTILLING BASINS, ETC.) TO
ENSURE THE CONTROL OF STORMWATER RUNOFF. THIS PLAN DESCRIBES THE MINIMUM
AMOUNT OF EROSION PROTECTION REQUIRED BY PROPOSED ACTIVITIES. IN THE
EVENT OF UNFORSEEN EROSION, OTHER MEASURES OF EROSION; CONTROL (EROSION
CONTROL ACTIVITIES SUCH AS THOSE LISTED ABOVE) WILL EE RiQUIRED.
i
3. 'URBIDITY BARRIERS MUST BE INSTALLED AT ALL LOCATIONS WHERE THE
POSSIBILITY OF TRANSFERRING SUSPENDED SOLIDS INTO THE REICEIVING WATERBODY
EXISTS DUE TO TH_ PROPOSED WORK. TURB'DITY BARRIERS MOST REMAIN IN PLACE
AT ALL LOCATIONS UNTIL CONSTRUCT T ON IS COMPLETED AND SILS ARE STABILIZED
AND VEGETATION HAS BEEN ESTABLISHED, THEREAFTER THE P, MITTEE WILL BE
RESPONSIBLE FOR THE REMOVAL OF THE BARRIERS, R
4. PERMANENT VEGETATIVE COVER MUST BE ESTABLISHED ON ALL :_-XPCSED LAND
SURFACES WIT,-IIN ONE YEAR FROM THE DATE THE CONSTRUCTIC4\1 IS COMPLETE.
5. CONTRACTOR SHALL PLACE SILT FENCE AS SHOWN ON THE PLA
PRIOR TO COMMENCEMENT OF CONSTRUC-ION,
