Notes:
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
inch of trunk diameter.
2. Install Silt Fence on the low elevation sides of each lot. Install Silt Fence outlets shown on
schematic/diagram and field adjusted, if necessary, for placement at low points. If lots are
contiguous and have different land owners or builders, each lot should have individual Silt
Fences.
3. Install required Silt Fence within 10 feet of property line to ensure there is no conflict with
septic system. It is the responsibility of the builder to ensure the installation of sediment
control measures does not impact the septic system and repair area(s).
4. At least one Construction Entrance/Exit is to be installed per lot.
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.
7. Details for Silt Fence, Silt Fence Outlets, Construction Entrances and other measures are
provided on additional sheets. Erosion and sediment control details are not drawn to scale.

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
