A. TREATMENT REQUIREMENTS
1. The SCM achieves runoff treatment. Y 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 N/A
build-out potential.
5. The project controls runoff through an offsite permitted Y or N N/A
SCM that meets the requirements of the MDC.
6. The net area of new BUA increase for an existing project �jY or N
has been accounted for at the appropriate design storm
level.
7. The SCM(s) meets all the specific minimum design ® 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 N/A
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 N/A
vegetation.
3. BUA that meets the requirements of NCGS 143-214.7 Y or N N/A
(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) N/A
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 N/A
setback as dispersed flow.
OAs-built OO N/E ©N/A
C. STORMWATER OUTLETS —the outlet handles the peak 0 or N
flow from the 10 year storm with no downslope erosion.
D. VARIATIONS
1. A variation (alternative) from the stormwater rule Y or N N/A
provisions has been implemented.
2. The variation provides equal or better stormwater control Y or N N/A
and equal or better protection of surface waters.
E. COMPLIANCE WITH OTHER REGULATORY PROGRAMS Qu 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 DY or N
storm depth.
G. CONTAMINATED SOILS— infiltrating SCM's are not QY or N
located in or on areas with contaminated soils.
H. SIDE SLOPES
1. Vegetated side slopes are no steeper than 3H:1V. QY or N
2. Side slopes include retaining walls, gabion walls, or Y or N N/A
other surfaces that are steeper than 3H:1V.
3. Vegetated side slopes are steeper than 3H:1V (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. 0 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 or N
provided.
K. DEWATERING — A method to drawdown standing water has DY or 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. QY or N
2. The access does not include lateral or incline slopes DY or N
>3:1.
N. DESIGNER QUALIFICATIONS (FAST-TRACK PERMIT) —
The designer is licensed under Chapters 89A, 89C, 89E, or QY or N
89F of the General Statutes.
