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.

MAINTENANCE OF EROSION AND SEDIMENTATION CONTROL MEASURES FOR LOT CONSTRUCTION
General - All measures will be inspected and corrections made after runoff producing rainfalls or at least once per week minimum. The builder will insure that the construction activities on an articular lot do not adverse) affect an of the installed erosion control measures. If lot construction dictates measures will be
p p 9 � p any Y Y
relocated on the lot to insure that the potential for sedimentation runoff is eliminated as much as possible. Silt fences and gravel construction entrances will be maintained as suggested in the erosion control manual. Sodding, seeding and mulching will be maintained to insure proper ground stabilizing cover.
Gravel Construction Entrance - The gravel pad should remain in a condition to prevent mud or sediment from leaving the construction site. This may require periodic topdressing with 2-inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all
objectionable materials spilled, washed, or tracked onto public roadways.
Silt Fence - Sediment fences should be inspected at least once a week and after each rainfall event. Any repairs should be made immediately. Damaged or decomposed fabric should be replaced promptly. Any sediment deposits that build up against the fence should be removed and disposed of properly to insure
that the removed sediment does not wash back against the fence. Adequate storage volume should be provided for behind the fence at tall times. Take care to not undermine the fence during cleanout operations.
Sodding - The sod should be properly maintained to insure that the grass take holds in the areas being secured. The sod should be watered as necessary to maintain adequate moisture in the root zone and prevent dormancy of the sod. The sod should not be mowed to close, since this could inhibit adequate growth
and stabilization of the root bed. The sod should be limed and fertilized as per soil type recommendations and type of grass recommendations when and if possible.
Grassing and Mulching - The area to receive grassing and mulching should be properly fertilized and limed as necessary as an initial step in soil preparation. Once the grassing has been placed, the area should be maintained as needed to insure that all areas are germinating properly. Any bare areas should be
repaired, and reseeded as soon as possible. If the time of year does not permit the establishment of a permanent grass, then a temporary grassing should be used until the growing season permits the use of a permanent grass.
Wattles - Wattles shall be inspected after significant rainfall events. Rills or gullies upslope of the wattle and any undercutting is to be repaired. Sediment deposits that impair the filtration capability of the wattle shall be removed when the sediment reaches one-third of the wattles functional freeboard height. Removed
sediment shall be deposited within the project in such a way that the sediment is not subject to erosion by wind or water.
Reinforced Silt Fence Outlet - Remove sediment deposits as necessary to provide adequate storage volume for the next rain to reduce pressure on the fence/outlet. Take care to avoid undermining the fence during cleanout. Remove and replace stone as necessary as it becomes clogged with sediment. Remove all
fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been property stabilized.
