After every runoff producing rainfall event, or at least monthly, whichever comes first:
1. Inspect the infiltration pond (s) for erosion, trash accumulation, grass coverage,
and general condition of the facility.
2. Repair eroded areas immediately, re -seed as necessary, keep side slopes and
bottom mowed, and remove trash.
3. Check any inlet piping, swales and catch basins. Repair broken piping, reseed
swales, and remove trash.
4. Inspect the bypass/overflow structure for blockage and deterioration. Remove
blockage and repair structure to originally approved design specifications.
5. Check the depth of the pond (s) every six months. If siltation has occurred -to the
point that only 75% of the original design depth is provided, remove the excess
silt to the original depth. Do not over -excavate, as this may cause the required
water table separation to be reduced, and may affect the ability of the system to
perform as designed,.

SUBJECT. Soil Evaluation for Proposed Stormwater Pond
Perkins Restaurant Site, Market Street and Gordon Road
LEES Project No. 31000-8-0953, Task 800
Eastern Soils Project No. 98-110
Dear Mr. Hubard:
At your request, we visited the subject site on February 19, 1998 for the puppose of
evaluating soil conditions in area of the proposed stormwater pond (stormwater
infiltration basin). The purpose of the field work was to identify the soil type in the area
of the pond, estimate the depth to the seasonal high water table (SHWT), and estimate the
permeability rate of the soil.
The approximate pond location was found in the field from taped measurements and
referring to a site plan that you provided. Four hand auger borings were made to a depth
of about 84 inches. Their locations are depicted with respect to geotechnical boring B-3
on the accompanying sketch. The soil characteristics were observed and the depth to free
water was measured. In addition, the depth to the water table was measured in an existing
geotechmcal boring (B-3), which was open at the time of the site visit. Soil permeability
was estimated using published data (Soil Survey of New Hanover County, Norrh Carolina,
USDA-SCS, 1977) and our observations of the soil.
The soils mapped in the area of the proposed restaurant by USDA-SCS soil scientists are
from the Kureb series (Kr). These soils are excessively well drained sands with a SHWT
found deeper than 72 inches. Typically, they have a surface laver of dark gray sand that is
about 3 inches thick. The subsurface soil to a depth of about 23 inches is light gray sand.
The underlying soil is brownish yellow sand in the upper part and pale brown sand in the

lower part. Dark brown bands and dark reddish brown lumps of sand are found between
depths of 26 and 51 inches. Baymeade (Be) soils are often found as inclusions in Kureb
map units. These soils are also sandy , but have a SHWT found at depths between 48 and
60 inches below the ground surface. They also have a sandy loam to loamy sand Bt
horizon.
The soils observed on the site resembled the Kureb series in texture and color in the upper
portion of the profiles. The soil material underlying the surface and subsurface soil layers
was brownish yellow or yellowish brown to pale brown sand to a depth of about 0 inches
in borings HA-1 and HA-2 and 65 inches in borings HA-3 and HA4. Below those depths
the soil was a light gray to gray sand. Free water was encountered in the borings at the
depth of the color change, or about 70 inches and 65 inches, respectively. The deeper
depth to free water was associated with a higher landscape position. Creotechnical boring
B-3 was located near the highest position on the landscape (estimated). Free water was
measured at a depth of 70 inches at the time of the site visit in boring B-3. The recent
record breaking rainfall amounts have undoubtedly pushed the water table to the
shallowest depths that can be expected.
According to SCS data presented in the soil survey report for New Hanover County, the
permeability of the Kureb soils is 6.0 to 20 LThr throughout the 89 inch soil profile
described. It is our opinion that the soils on the subject site haae a permeability on the
lower end of that range. We would suggest using a permeability of no greater than 6.0
irift for drawdown estimates.
If we can be of further assistance or if you have any questions about this report please
contact us.
Sincerely,
W.R. (Bill) Dunlop, Jr., LSS
