GENERAL NOTES:
1. CONTRACTOR IS RESPONSIBLE FOR FIELD VERIFYING ALL EXISTING UTILITIES,
ABOVE AND BELOW GROUND, PRIOR TO CONSTRUCTION.
2. CONTRACTOR IS RESPONSIBLE FOR DISPOSAL OF ALL WASTE MATERIALS
GENERATED THROUGH DEMOLITION AND GRUBBING ACTIVITIES.
3, SURVEY AND TOPOGRAPHICAL INFORMATION AS SHOWN ON THESE PLANS
HAVE BEEN PROVIDED BY MICHAEL UNDERWOOD AND ASSOCIATES FROM
WILMINGTON, NORTH CAROLINA.
4. THERE ARE NO WETLANDS ON THIS SITE.
5, THE DISTURBANCE FOR THIS SITE IS TO BE KEPT TO A MINIMUM.
6. ALL DISTURBED AREAS NOT TO BE STABILIZED WITH IMPERVIOUS SURFACE
TO BE SEEDED, FERTILIZED, AND MULCHED WITHIN 15 CALENDAR DAYS OF
GRADING ACTIVITIES.
7. ALL STORM DRAIN DEVICES ARE TO PROVIDE POSITIVE DRAINAGE.
8. EROSION AND SEDIMENTATION CONTROL PRACTICES ARE TO BE REMOVED
IN THE LOCATION THAT THE STORMWATER SYSTEM IS BEING INSTALLED AT
THAT TIME. THE STORMWATER POND IS DESIGNED TO BE USED AS A
SEDIMENT BASIN FOR EROSION CONTROL PURPOSES. THE POND MUST BE
CLEANED OUT AFTER THE ENTIRE DRAINAGE BASIN HAS BEEN STABILIZED
AND PRIOR TO USE AS A WET DETENTION BASIN.
9. STORMWATER PUMPS ARE TO REMAIN AVAILABLE FOR OPERATION AND
MAINTENANCE AND EMERGENCY DRAINING OF THE POND AND DOCK PIT.
10. ALL RUNOFF FROM FUTURE DEVELOPMENT MUST BE DIRECTED TO THE
DRAINAGE SYSTEM OR TO THE STORMWATER POND FOREBAY.
