2. Soil disturbance is defined as areas where any of the following
features are evident: depressions or wheel tracks, soil
displacement, active soil erosion, soil compaction, or removal of
vegetated canopy
3. Protect all existing vegetation where feasible
4. All earth moving activities shall be made in a manner that
maintains slope stability and remains in compliance with osha
standards.
5. Locate all utilities prior to digging.
6. Install all stormwater control measures only after all sediment and
erosion on -site is controlled and site is stabilized and seeded.
7. During installation, the contractor shall notify Equinox or owner of
any conditions which may be harmful to plant life, such as
hazardous materials, etc.
8. Where conflicts occur between notes, drawings, or specifications,
the contractor shalt not proceed with the affected work until the
landscape architect issues a clarification.

GRADING:
17. All spot grades and contours show finish grade.
18. All cut slopes and fill slopes to be 2:1 and 3:1 respectively unless
otherwise indicated.
19. Any slopes associated with BMPs shall not exceed 3:1.
PLANTING:
20. Call 811 utility locations prior to digging.
21. All planting is to meet requirements set forth in the North Carolina
BMP Manual 2007 related to stormwater wetlands.
STORMWATER CONTROL MEASURES:
22. Stormwater BMP to be installed only after all sediment and erosion
on -site is controlled and site is stabilized and seeded.
23. Construction of wetland may only begin after the entire
contributing drainage area has been stabilized. it may be
necessary to block certain curb or other inlets while the wetland
area is being constructed.
24. To convert the area from sediment basin to wetland, the facility
must be completely dewatered, dreged, and regraded to the
design dimensions.
25. Check for existing utilities prior to construction.
26. Schedule a preconstruction meeting with the engineer. check the
boundaries of the contributing drainage area and inlet elevations
to ensure they conform to design.
27. Divert stormwater away from the wetland area until it is
completed.
28. Clear and strip project area to desired subgrade. pre-treatment
cells (forebays) shall be excavated first and then sealed to trap
sediments.
29. Clear and excavate wetland area and place impermeable
subgrade.
30. Excavate the core trench for the embankment and install the
spillway pipe, outflow structure, and anti -seepage collars as

2. Keep the center stone section at least 9 inches below natural ground level
where the dam abuts the channel banks.
3. Extend stone at least 1.5 feet beyond the ditch bank (Figure 6.83b) to keep
water from cutting around the ends of the check dam.
4. Set spacing between dams to assure that the elevation at the top of the
lower dam is the same as the toe elevation of the upper dam.
5. Protect the channel after the lowest check dam from heavy flow that could
cause erosion.
6. Make sure that the channel reach above the most upstream dam is stable.
7. Ensure that other areas of the channel, such as culvert entrances below the
check dams, are not subject to damage or blockage from displaced stones.

Figure 6.83b Stone check dam stone should be placed over the channel banks to keep water from cutting around the
dam.
Maintenance Inspect check darns and channels at least weekly and after each significant (1/2
inch or greater) rainfall event and repair immediately. Clean out sediment,
straw, limbs, or other debris that could clog the channel when needed.
Anticipate submergence and deposition above the check dam and erosion from
high flows around the edges of the dam. Correct all damage immediately. if
significant erosion occurs between dams, additional measures can be taken
such as, installing a protective riprap liner in that portion of the channel
(Practice 6.31, Riprap-line and Paved Channels).
Remove sediment accumulated behind the dams as needed to prevent damage
to channel vegetation, allow the channel to drain through the stone check dam,
and prevent large flows from carrying sediment over the dam. Add stones to
dams as needed to maintain design height and cross section.
