A. TREATMENT REQUIREMENTS
1. The SCM achieves runoff treatment. or N
2. The SCM achieves runoff volume match. Y or N
3. Runoff from offsite areas and/or existing BUA is Y or N
bypassed.
4. Runoff from offsite areas and/or existing BUA is directed Y®or N
into the permitted SCM and is accounted for at the full
build-out potential.
5. The project controls runoff through an offsite permitted Y or®
SCM that meets the requirements of the MDC.
6. The net area of new BUA increase for an existing project 0 or N
has been accounted for at the appropriate design storm
level.
7. The SCM(s) meets all the specific minimum design 0 or N
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.
3. BUA that meets the requirements of NCGS 143-214.7 Y or N
(b2)(2) is located in the setback.

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
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 Oor N
flow from the 10 year storm with no downslope erosion.
D. VARIATIONS
1. A variation (alternative) from the stormwater rule Y or N
provisions has been implemented.
2. The variation provides equal or better stormwater control Y or N
and equal or better protection of surface waters.
E. COMPLIANCE WITH OTHER REGULATORY PROGRAMS Y 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 YOor N
storm depth.
G. CONTAMINATED SOILS— infiltrating SCM's are not Y or N
located in or on areas with contaminated soils.
H. SIDE SLOPES
1. Vegetated side slopes are no steeper than 3H:1V. Y or O
2. Side slopes include retaining walls, gabion walls, or 0 or N
other surfaces that are steeper than 3H:1V.
3. Vegetated side slopes are steeper than 3H:1V (provide Oor N
supporting documents for soils and vegetation).
I. EROSION PROTECTION
1. The inlets do not cause erosion in the SCM. INP or N
2. The outlet does not cause erosion downslope of the 0 or N
discharge point during the peak flow from the 10 year
storm.
J. EXCESS FLOWS—An overflow/ bypass has been 0 or N
provided.
K. DEWATERING — A method to drawdown standing water has YOor N
been provided to facilitate maintenance and inspection.
L. CLEANOUT AFTER CONSTRUCTION —the SCM has been 0 or N
cleaned out and converted to its approved design state.
M. MAINTENANCE ACCESS
1. The SCM is accessible for maintenance and repair. Y or N
2. The access does not include lateral or incline slopes Y or N
>3:1.
N. DESIGNER QUALIFICATIONS (FAST-TRACK PERMIT) —
The designer is licensed under Chapters 89A, 89C, 89E, or Y or N
89F of the General Statutes.

5. SCM IS ON-SITE
B
VEGETATED SETBACKS ARE REQUIRED FOR THIS PROJECT BUT NO WATERS OF
THE STATE ARE PRESENT ON-SITE SO NO VEGETATED SETBACKS HAD TO BE
PROTECTED.
D
NO VARIATIONS.
G
NO INFILTRATION OR CONTAMINATED SOILS.
