CU INLET 1. If needed, Tree Protection fencing should be installed along the buffer zone, wetland
boundary and/or around protected trees, providing a radius of at least 1.25 feet for each
LEGEND inch of trunk diameter.
2. Install Silt Fence on the low elevation sides of each lot. Install Silt Fence outlets shown on
FLOW DIRECTION schematic/diagram and field adjusted, if necessary, for placement at low points. If lots are
SILT FENCE contiguous and have different land owners or builders, each lot should have individual Silt
Fences.

5. Waste bins and other areas dedicated for managing building material waste shall be at
least 50 feet away from storm drain inlets or drainage ditches unless it can be shown that
no other alternative exists. If this separation cannot be achieved, these areas must be
contained behind Silt Fence.
6. Inlets downstream of disturbances should be protected; streets should be swept when
sediment from the construction activity is present.

General Erosion Control Notes
1. Only the areas shown shall be disturbed.
2. All disturbed areas shall be grassed and mulched as soon as
possible and maintained until permanent cover is established.
Pursuant to G.S.113A(3), provisions for permanent ground cover
sufficient to restrain erosion must be accomplished for all
disturbed areas within 14 working days or 90 calendar days
(whichever is shorter) following completion of construction.
