Consultant's Certification (MDC 15A NCAC 02H .1003)
Project Density and Built-Upon Area OAs-built ON/E (3)N/A
1. The project has areas of high density based on natural drainage Y or NO
area boundaries, variations in land use or construction phasing.
2. The project's built-upon area does not exceed the maximum limit OY or N
specified in the permit.
Dispersed Flow OAs-built ON/E (3)N/A
1. The project maximizes dispersed flow through vegetated areas YOor N
and minimizes channelized flow.

Permit No. SW3220304
Vegetated Conveyances OAs-built OO N/E ON/A
1. Stormwater that is not released as dispersed flow is transported O or N
by vegetated conveyances.
2. The project has a minimal amount of non-vegetated conveyances O or N
to reduce erosion.
3. Other than minimal piping under driveways and roads, no piping Y or NO
has been added beyond what is shown on the approved plans.
4. Side slopes are no steeper than 3H:1 V. YO or N
5. The conveyance does not erode in response to the peak flow from 0 or N
the 10-year storm.
Curb outlet systems (if applicable) OAs-built OO N/E ON/A
1. The swale or vegetated area can carry the peak flow from the 0 or N
10-year storm at a non-erosive velocity.
2. The longitudinal slope of the swale or vegetated areas does not O or N
exceed 5%.
3. The swale has a trapezoidal cross-section and a minimum bottom O or N
width of two feet.
4. The minimum length of the swale or vegetated area is 100 feet. YO or N
5. Side slopes are no steeper than 3H:1 V. YO or N
6. The project utilizes treatment swales designed per Section .1061 Y or NO
in lieu of the curb outlet system requirements.
Vegetated Setbacks (if applicable) OAs-built OO N/E ON/A
1. The width of the vegetated setback is at least 50'. OY or N
2. The width of the vegetated setback has been measured from the
normal pool of impounded waters, the MHW line of tidal waters, YO or N
or the top of bank of each side of rivers or streams.
3. The vegetated setback is maintained in grass or other vegetation. OY or N
4. BUA that meets the requirements of NCGS 143-214.7(b2)(2) is Y or NO
located in the setback.
5. BUA that does NOT meet the requirements of NCGS 143-
214.7(b2)(2) is located within the setback and is limited to:
• Publicly-funded linear projects (road, greenway, or sidewalk) Y or NO
• Water dependent structures
• Minimal footprint uses such as poles, signs, utility
appurtenances, and security lights.
6. The amount of BUA within the setback is minimized, and O or N
channeling of the runoff from the BUA has been avoided.
7. Stormwater is not discharged (via swale or pipe) through a
vegetated setback. Stormwater is released at the edge of the OY or N
setback and allowed to flow through the setback as dispersed flow.

Outlets OAs-built OO N/E ON/A
1. Stormwater outlets do not cause erosion downslope of the 0 or N
discharge point during the peak flow from the 10-year storm.
Variations OAs-built OO N/E OO N/A
1. The project has variations from the MDC that were not previously Y or NO
approved. (Modification may be required.)
Deed restrictions (if applicable) OAs-built OO N/E ON/A
1. Deed restrictions are recorded and ensure that the project and
the BUA will be maintained in perpetuity consistent with the Y or N X
permit, approved plans, and specifications.
For Subdivisions Only (Residential or Commercial) OAs-built OO N/E OO N/A
1. The number of platted lots is consistent with the approved plans. Y or N X
2. The project area is consistent with the approved plans. Y or N X
3. The layout of the lots and streets is consistent with the approved Y or N X
plan.
4. The width /radius of streets, paved accesses, cul-de-sacs and Y or N X
sidewalks is consistent with the approved plan.
5. No piping, other than those minimum amounts needed under a Y or N X
driveway or under a road, has been added.
6. The lot grading, road grading, vegetated conveyances, piping, Y or N X
inverts, and elevations are consistent with the approved plans.
Provide an explanation below for every MDC that was not met, and for every item marked "N/A" or
"N/E." Attach additional pages as needed.
Small amount of 10" dia. piping added at Dispatch Building perimeter to avoid steep side slopes between
sidewalk and curb. Drainage is routed through grass areas to provided inlets and pipe discharges to a
vegetated swale per plan and then to wooded buffer area.
