Certification;
Dear Scott: .
Barrier Island Station - Kitty Hawk, Phase II North (North) and
(South) is construction complete in substantial conformity with permit
SW7130717' Phase II North (North) and .(South) as revised.by Drawings
C-122, Rev 6, and C-123, Rev 2, copy attached.
Attached.please find executed copy of the Designer's Certification
and Certification Requirements check sheet.
Revisions depicted on Drawing C-122, Rev 6 include:
1. Deletion of pavement' regrading :as set out in my letter to Scott
Vinson August 12, 2014.
and other minor field revisions:
2. Revision of the fabrication and installation details of the drop
inlet north of the 1600 Building (DI#1) and shift of the culvert
alignment at BASS to allow the culvert discharge to.miss a large
tree and roots.
3. Addition of a drip -line swale at the southern corner of the 1500
Building leading,to infiltration basin BAS10.
4. Addition of a berm running northeast from the retaining wall
south of the 1600 Building to provide separation between conveyed
runoff and wetlands, and between infiltration basin BASS and
wetlands, and addition of a berm running southeast from the
retaining wall to provide separation between conveyed runoff and

Revisions depicted on Drawing C-123,.Rev 2 include:
1. Deletion of Laundry Building gutters and downspouts as set out in
my letter to Scott Vinson August 12, 2014.
and other minor field revisions:
2. The retaining wall at the northwestern corner of the Laundry
Building was constructed with an impermeable facing and the
western end of wall was extended west with a return to the south
to allow the transfer swale from the pavement to infiltration'
basin BAS2 to be moved to immediately adjacent 'to the retaining
wall, the nature trail to be shifted south, and the elevated.
walkway northwest of the building to be eliminated.
3. A stone apron was added at the drip edge of the shed roof at the
south end of the Laundry Building to stabilize the drip area.
4. Stone slopeprotection and wheel stops were added along the BASS
slope receiving pavement runoff or occasional vehicle wheel
incursions to stabilize and protect the slope against erosion or
rutting.
5. The swale, infiltration basin BAS4 and the wooden walkways were
slightly reconfigured to accommodate the basketball court
southern gate location.

Re: Stormwater Management Permit SW7130717:
Barrier Island Station -.Kitty Hawk, Phase
III North and North-Central: Designer's"
>'Certification^"
Dear Scott:
Barrier Island Station - Kitty Hawk, Phase III North and North-Central
is construction complete in substantial conformity with permit
SW7130717, Phase III N&N-C, revised Drawing'C-321'; Rev 5, copy
attached.
Attached please find executed copy of the Designer's Certification
and Certification Requirements check sheet.
Minor field revisions depicted on Drawing C-321, Rev 5 include:
1. The trench drain across the drive and parking area south, of the
2500 Building was replaced with a drop inlet in front of the
building and a culvert under/across the parking and drive area.
The tributary area served is slightly reconfigured, and the
tributary area itself is slightly revised.
2. Dry Infiltration basin BAS5 was reconfigured to avoid conflict
with an existing stormwater swale serving Phase II South.
Note: the tributary area affected by revisions #1 and #2 is unchanged.
3. A drop inlet was added at the east end of the culvert under the
drive east of .the 2600 Building to reduce the swale depth and
steep shoulder slopes adjacent to the drive. There was no change
in tributary area or culvert capacity.
4. Rock slope protection was added to the pavement runoff area along
the northern edge of infiltration basin BAS2.

5. Dripline swales were modified slightly at the 2700 Building and
the 2800 Building to better coordinate with existing site
topography and stable local infiltration areas, with no
significant change of runoff capture or local infiltration.
6. Infiltration basin BAS3 (formerly about half -way between the 2600
and 2800 Buildings) was deleted because of the presence of
shallow underground electrical distribution lines and other
utilities. The 423 sf tributary area and 71 cf runoff to BAS3 is
now served by local infiltration in the same area or runoff to
the drop inlet leading to BAS4, which has substantially greater
capacity than the 11,000 sf and 2,425 cf runoff served. The
schedule is revised accordingly.
7. The parkway curb along the eastern edge of the drive from the
2500 Building to southeast of the 2600 Building was replaced by a
stabilized soil berm along the edge of pavement (observation of
the as -built berm indicates satisfactory performance and no berm
erosion).
8. The southern end of the retaining wall northwest of the 2800
Building was revised in the field from an approximately 90-degree
return to an approximately 45-degree return to minimize
transition grading (not shown on the drawing).
9. The southeastern corner of the parking lot pavement west of the
2800 Building was extended in the field slightly to the east,
resulting in an inconsequential increase in pavement area and an
inconsequential narrowing of the rock -lined transfer swale (which
probably will never see any actual water flow).
