ENGINEERING & CONSTRUCTION
Seasonal High Water Table Analysis for proposed Stormwater BMP at the Marquee Station
Project in Fuquay - Varina, Wake County, NC.
On August 2, 2012 Chris Flowers, NC Licensed Soil Scientist 1307, of SEPI Engineering and Construction conducted
a soil evaluation at the above mentioned site for the specific purpose of determining the depth of the seasonal
high water table (SHWT) at a proposed stormwater BMP location. Marquee Station is located north of the
intersection of Mill Creek Drive and Hwy 401 in Fuquay- Varina, Wake County, NC. The proposed bio- retention area
BMP is generally located in the northernmost corner of the project site. Prior to the soil evaluation the proposed
extent and centerline of the BMP was staked in the field. To assess the depth (elevation) of the SHWT a hand
auger boring was completed within the footprint of the proposed BMP to a depth of six feet from the existing
ground surface. The following were performed at the soil boring location: a general soil profile description,
seasonal high water table analysis based on soil color and /or mottling, and an apparent water table measurement
(ground water rise in boring hole).
Evaluation and Results
The soil boring was conducted within the interior of the proposed BMP footprint at a point 27 feet from the dam
stake along the center line. Based on information provided by the project engineer the ground surface elevation at
the bore hole location is 382.5 feet. The Natural Resource Conservation Service Wake County Soil Survey lists the
site as falling within the (NoC) Norfolk loamy sand, 6 to 10% slopes map unit. Based on the soil properties
observed in the field the soil present at the boring location is likely Norfolk. Norfolk soils generally consist of very
deep, well drained, moderately permeable soils on summits, shoulders, and backslopes in the lower, middle, and
upper coastal plain (Cawthorn, 1970).
Below is a general soil profile description as well as a picture of the profile observed at the boring.

Figure 1. Soil Profile
Based on the observed soil properties the seasonal high water table is located 48 inches from the ground surface
or at 378.5 feet elevation. The apparent water table (free water in bore hole) was not observed within the bore
hole after a period of 1 hour.
A secondary boring was taken at another point within the footprint of the proposed BMP to ensure generally
consistent soil properties across the footprint. The secondary boring was not described in the detail as the above
boring but was sufficient to confirm consistent soil properties across the BMP.

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BUT elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after e,�,*ery storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be a-railable upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
