A. TREATMENT REQUIREMENTS
1. The SCM achieves runoff treatment. U or N
2. The SCM achieves runoff volume match. ! Y or N N/A
3. Runoff from offsite areas and/or existing BUA is U 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 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.
j_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. _
I CFAs-built M N/E ( N/A
C. STORIRVItATER OUTLETS—the outlet handles the peak I Q or N
tlrf4a_ -10 year storm with no downslope erosion_
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 COIiPL/ANCE WITH OTHER REGULATORY PROGRAMS

supporting documents for soils and vegetation).
I. EROSION PAN
1. The inlets do not cause erosion in the SCM. _ 0 or N
2. The outlet does not cause erosion downslope of the Q or N
discharge point during the peak flow from the 10 year
storm.
J. EXCESS FLOWS—An overflow/bypass has beenprovided 0 or N
