Division, except as noted on the "AS -BUILT" drawings, such that the intent of the stormwater rules
and statutes has been preserved.
Check here if this is a partial certification. Section/phase/SCM #?, Wet Pond B
Check here if this is a part of a Fast -Track As -Built Package Submittal per .1044(3).
Check here if the designer did not observe the construction, but is certifying the project.
Check here if pictures of the SCM are provided.

2. The SCM achieves runoff volume match.
Y or N
N/A
3. Runoff from offsite areas and/or existing BUA is
bypassed.
Y or N
4. Runoff from offsite areas and/or existing BUA is directed
into the permitted SCM and is accounted for at the full

level.
Y or N
N/A
7. The SCM(s) meets all the specific minimum design
criteria.
B. VEGETATED SETBACKS / BUA
1. The width of the vegetated setback has been measured Y or N
from the normal pool of impounded waters, the MHW
line of tidal waters, or the top of bank of each side of
rivers or streams.
2. The vegetated setback is maintained in grass or other Y or N
vegetation.

4. BUA that does not meet the requirements of NCGS 143-
Y or N
214.7 (b2)(2) is located within the setback and is limited
to:
a. Publicly funded linear projects (road, greenway
N/A
sidewalk)
b. Water -dependent structures
c. Minimal footprint uses (utility poles, signs, security
lighting and appurtenances)
5. Stormwater that is not treated in an SCM is released at
Y or N
the edge of the setback and allowed to flow through the
setback as dispersed flow.

C. STORMWATER OUTLETS — the outlet handles the peak
O or N
flow from the 10 year storm with no downslo a erosion.
D. VARIATIONS
1. A variation (alternative) from the stormwater rule
Y or N
0
provisions has been implemented.
2. The variation provides equal or better stormwater control
Y N
N/A
and equal or better protection of surface waters.
or
E. COMPLIANCE WITH OTHER REGULATORY PROGRAMS
O or N
has been met.
F. SIZING -the volume of the SCM takes the runoff from all
surfaces into account and is sufficient to handle the required
Y or N
N/A
storm depth.
G. CONTAMINATED SOILS — infiltrating SCM's are not
Y or N
N/A
located in or on areas with contaminated soils.
H. SIDE SLOPES
1. Vegetated side slopes are no steeper than 3H:1 V.
Y or N
N/A
2. Side slopes include retaining walls, gabion walls, or
Y or N
N/A
other surfaces that are steeper than 3H:1 V.
3. Vegetated side slopes are steeper than 3H:1 V (provide
Y or N
N/A
supporting documents for soils and vegetation).
I. EROSION PROTECTION
1. The inlets do not cause erosion in the SCM.
Y or N
N/A
2. The outlet does not cause erosion downslope of the
Y or N
discharge point during the peak flow from the 10 year
storm.
J. EXCESS FLOWS — An overflow / bypass has been
y0 or N
provided.
K. DEWATERING — A method to drawdown standing water has
Y or N
N/A
been provided to facilitate maintenance and inspection.
L. CLEANOUT AFTER CONSTRUCTION — the SCM has been

Provide an explanation for every MDC that was not met, and for every item marked "N/A" or "WE",
below. Attach additional pages as needed:
B. Vegetated Setbacks - 3,4 N/A, no BUA within the vegetated setbacks
D. Variations - 2 N/A, no variations have been implemented
G. Contaminated Soils - N/A, no infiltrating SCMs on the project.
