RE: Bayview Property
Storm water Management Permit SW7071010
Mr. Thorpe,
The above project has not been constructed, the economic down turn has
halted further development on this project.
We hope to address this project in the near future; it is our intent to build on
this property and complete required permanent ponds.
Thank you for your help. I can be reached at 919-880-4411 cell.

Dear Ms. Tipton:
This letter is to inform you of certain conditions of your stormwater permit that have not been
met. A Division of Water Quality file review confirms that a certification of completion has not been
submitted. Permit condition number II. 6 states "Upon completion of construction, prior to issuance of
a Certificate of Occupancy, and prior to operation of this permitted facility, a certification must be
received from an appropriate designer for the system installed certifying that the permitted facility has
been installed in accordance with this permit, the approved plans and specifications, and other
supporting documentation. Any deviations from the approved plans and specifications must be noted
on the certification. A modification may be required for those deviations."
Please provide a copy of the certification or a statement that the project has not been
constructed to this Office at the letterhead address within 30 days of receipt of this letter. If you have
questions, please feel free to contact me at (252) 948-3923.
Sincerely,

Subject: Stormwater Review SW7071010
James Joyce Storage
Beaufort County
Dear Ms. Tipton:
This office received a Coastal Stormwater permit application for the subject project on December 5, 2007,
A preliminary review of your project indicates that before a State Stormwater permit can be issued the following
additional information is needed:
1. The application submitted is for clearing and grading only, however the plans show construction of
impervious area and stormwater treatment. Application SWU — 101 will need to be completed. This
application can be found on our web site.
2. The existing application was signed by your consultant. A managing member of the LLC must sign
the application or we will need a letter from the managing member of the LLC authorizing someone
else to sign for him or her.
3. A soils report must be prepared by a qualified professional that includes the results of on site borings,
a comparison of the findings to the local soils maps and an estimate of the soils permeability and the
seasonal high water table.
4. The phosphorus index for the soil planting mix should be between 10 and 30.
5. Please include a stormwater narrative.
6. The plans should clearly delineate the drainage basins on the site and clearly indicate how the
stormwater will be routed to the bioretention basin.
7. For a grassed bioretention basins sod should be specified rather than seeding.
B. If there are any blue line streams located on the site they must be shown on the plans along with the
appropriate buffer set backs.
9. A signed and notarized operation and maintenance agreement is required. See our web site for
samples.
10. Part III of the Bioretention cell supplement must be printed from our web site, filled out and submitted
along with all other required information.
The above requested information must be received in this office prior to March 6, 2008 or your application
will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including
the application fee. If you need additional time to submit the required information, please mail or fax your request
for time extension to this office at the Letterhead address.

Stormwater Narrative
The site is located approximately 2 miles east of Bath, North Carolina. Erosion measure have already
been installed in accordance with an approved plan. These measures are monitor regularly and check
after every rainfall event.
Stormwater runoff from the site will be treated with a bioretension basin located on the north east edge
of the site. All runoff to the basin is from on site ( approximately 2. 5 acres.) This will be used to meet
the 85% reduction in total suspended solids.
Soils on the site are predominately Tomotley fine sandy loam. On site testing indicated that the high
seasonal groundwater is 1 foot below the surface. The infiltration rate is less that 2 inches per hour. A
copy the report is attached.

Description
Saturated hydraulic conductivity (Ksat) refers to the ease with which pores in a
saturated soil transmit water. The estimates are expressed in terms of micrometers
per second. They are based on soil characteristics observed in the field, particularly
structure, porosity, and texture. Saturated hydraulic conductivity is considered in
the design of soil drainage systems and septic tank absorption fields.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.
The numeric Ksat values have been grouped according to standard Ksat class
limits.

As requested by Mr. John Tucker, representing John A. K. Tucker, PE, a representative of Terracon
Consultants, Inc. was on site today to provide visual soil classification, to determine the depth to
the seasonal high water table and to obtain a soil sample for flexible wall permeability testing.
The areas explored were selected by Terracon and are indicated on the attached drawing. Please note
that boring HA-2 was located on the raised area between the two bays for the retention basin.
Borings HA-1 and HA-3 were located at the west and east ends of the retention basin, respectively.
The three borings are discussed.as follows:
HA-1 - Soils at this location consist of pale brown (10YR-6-3) slightly clayey silty fine sand to a
depth of one foot. At one foot, the slightly clayey silty fine sand is mottled grayish brown
(10YR-5-2). A seasonal high water table at a depth of one foot is indicated by the appearance of
the above mentioned mottles.
HA-2 - This boring was positioned in the raised area between the two bays of the bioretention basin.
Very dark brown (10YR-2-2) silty fine sand (topsoil) is present to a depth of one foot. This soil
texture remains consistent to a depth of three feet with slight variations in soil color (very dark
grayish brown, 10YR-3-2; very dark brown, 7.5YR-2.5-3; dark brown, 7.5YR-3-4). At three feet, the
sand is mottled light brownish gray (10YR-6-2). The depth to the seasonal high water table is
placed at a depth of one foot, based on soils with a chroma value of 2.
HA-3 - Soils at this location consist of very dark brown (10YR-2-2), dark brown (10YR-3-2) and black
(10YR-2-1) silty fine sand. The depth to the seasonal high water table is placed at a depth of one
foot, based on a soil chroma value of 2, or less.
As the soil texture is consistent at the three locations explored, one composite sample was obtained
for flexible wall permeability testing. The sample was obtained from a depth of 0.5 to 1.0 feet
below the existing site grades. The permeability test results obtained are attached.
The tests were performed in general accordance with applicable ASTM, AASHTO, or DOT test methods. This report is exclusively for the use of the client
indicated above and shall not be reproduced exceptin full without the written consent of our company. Test results transmitted herein are only applicable
to the actual samples tested at the location(s) referenced and are not necessarily indicative of the properties of other apparently similar or identical

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 BMP 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 betaken 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 every 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 available upon request. .
Inspection activities shall be performed as follows. Any problems that are found shall
