Title 15A NCAC 2H.100, the Stormwater Management Regulations, deed restrictions and protective covenants are
required where lots will be subdivided and sold. Deed Restrictions and protective covenants are necessary to ensure that
the development maintains a "built -upon" area consistent with the applicable regulations governing the density level.
A DWQ file review confirms that copies of the recorded deed restrictions have not been provided to this Office. Failure to
record the required deed restrictions constitutes a.violation of Permit Number SW7080911 which states "Deed restrictions
are incorporated into this permit by reference and must be recorded with the Office of Register of Deeds prior to the sale
of any lot. In addition, a copy of the recorded restrictions must be received by this Office within 30 days of the date of
recording. Recorded deed restrictions must include as a minimum certain statements related to stormwater management
as outlined in both the permit and the notarized statement signed by the applicant at the time of permit request submittal.

As per your e-mail request, I have revised sheet 25 of the Grading and Drainage Plans.
Specifically, the following revisions were made:
I. Cattails were removed from the planting list and replaced with alternative plantings.
2. Main pond and forebay bottom elevations were coordinated.
3. Sediment Removal Benchmark table was revised to indicate a removal elevation of 3.2'
Attached, please find two full-size copies of plan sheet 25 for inclusion in this plan set. If you
have any questions or need additional information please contact me at 252-261-3300.

Subject: Stormwater Review SW708091 1
Griffins Beach PUD
Beaufort County
Dear Mr. Hollan:
This office received a Coastal Stonnwater permit application and plans for the subject project on
September 15, 2008 with additional information received on January 12, 2009. A preliminary review of the project
indicates that before a State Stormwater permit can be issued the following additional information is needed.
1. The BMP stormwater design manual does not recommend that cattails be wetland plant to be planted on the
wet pond vegetated shelf due to fact that it is an aggressive species that will crowd out all other planted
wetland species and has been shown to self establish over time. Please replace the two cattail species on
sheet 25 under the wetland planting table.
2. It appears that the main pond bottom (2.0) and the forebay bottom (-1.0) has been transposed on the wet
pond cross sectional detail.
3. There is a minor discrepancy in the sediment removal benchmark for infiltration basin #12. It is labeled on
sheet 25 as 3.4' and should be 3.2'. Please verify and correct if needed.
4. Please do not forget to have any plans, calculations, supplements, narrative, etc, revised, signed, sealed and
dated as necessary when re -submitting
The above requested information must be received in this office prior to April 20, 2009 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.
You should also be aware that the Stormwater Rules require that the permit be issued prior to any
development activity. Construction without a permit is a violation of 15A NCAC 2H.1000 and North Carolina
General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.
Please reference the Stormwater Project Number above on all correspondence. if you have questions, please
feel free to contact me at [phone].

Low Density Residential Subdivisions JAN 12 2009
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000, the Stormwater Management Regulations, deed restrictions o
and protective covenants are required for Low Density Residential Subdivisions where lots will be
subdivided and sold. Deed restrictions and protective covenants are necessary to ensure that the
development maintains a 'built -upon" area consistent with the applicable regulation goveming the density
level.
I, Uiliam E Noliun Jr. acknowledge and affirm by my signature below, that I will cause the
following deed restrictions and protective covenants to be recorded for 6y f6s eauk YUDroF. t- 14-
prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number '5W'70609 I I as issued by the Division of Water Quality under
NCAC 2H.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming
under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express
written consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
6. The maximum allowable built -upon area per lot is 1 ono square feet. This allotted amount
includes any built -upon area constructed within the lot property boundaries, and that portion of the
right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but
is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, and coquina, but does
not include raised, open wood decking, or the water surface of swimming pools.
7. In the case of a lot within CAMA's regulated AEC, where the Division of Coastal Management
calculates a different maximum allowable built -upon area for that lot than is shown herein, the
governing maximum built -upon area for that lot shall be the most restrictive of the two.
8. Filling in or piping of any vegetative conveyances (ditches, swales, etc.) associated with the
development except for average driveway crossings is strictly prohibited by any persons.
9. Each lot will maintain a 30 foot wide vegetated buffer between all impervious areas and surface
waters.
10. All roof drains shallferminate at least 30 foot from the mean high water mark of surface waters.

Stormwater Review SW7080911
Griffins Beach PUD
Beaufort County
This office received a Coastal Stormwater permit application and plans for the subject project on
September 15, 2008. A preliminary review of the project indicates that before a State Stormwater permit can be
issued the following additional information is needed.
1. For infiltration basin #3, the supplement and one part of the calculations give a storage elevation of 4.5
fmsl., where as the plans and another portion of the calculation gives 4.6 fmsl as the storage elevation. It is
believed that 4.6 fmsl is the intended and needed elevation, please verify and revise plans as needed.
2. Please note that the Bottom Surface Area on the supplement form for Basin #8 of 10,883sf is incorrect and
according to the provided calculations should be 6,955sf..
3. Because the marina is not being officially proposed at this time to the Department, please remove it from
the stormwater plans. Please also remove only that portion of the boat ramp from the slotted collection
drain down into the water. All other proposed impervious area can be left shown as is.
4. Basin #8 has 3.21 ac-in of volume coming into the basin. Please split the flow and provide multiple inlets
with no one have more than 2 ac-in volume or provide a distribution device within the bottom of the basin.
5. The application shows in drainage area 12 64,568sf of impervious area, while the numbers add up to
69,809sf. The calculations for DA # 12 calls for permeable pavement but the neither the narrative nor plans
mention it. Please discuss any requested impervious area credits in the narrative, label the permeable
pavement on the plans including a detail, and provide a supplement form with an O&M signed document.
If the pavement is not located near existing soil borings, additional borings may be needed to verify
permeability and the seasonal high water table.
6. Please provide a copy of Attachment A — Boring Logs and Hydraulic Conductivity Determination that is
noted to be bound separately from the narrative. The copy of this attachment was not found in the
application package.
7. Please provide an original signed & notarized copy(s) of the proposed deed restrictions found on DWQ's
website for lots that are to be subdivided & sold.
8. Please do not forget to have any plans, calculations, supplements, narrative, etc. revised, signed, sealed and
dated as necessary when re -submitting

MEMORANDUM
Jute 30, 2008
Subject: Griffins Beach
Boring Logs and Hydraulic Conductivity Determination
To: Andy Deel, P.E.
From: Warren Eadus, L.C.
JAN 1 2 2009
On June 21, 2008 Brian Rubino, L.G. and I installed a total of sixteen piezometers in locations as directed by you at
the proposed Griffins Beach PUD Development near Washington in Beaufort County, North Carolina. On June 24,
2008 a slug test (falling head) was performed in each of the sixteen piezometers. The work was conducted to
understand the saturated hydraulic conductivity (K) of the soils within the proposed infiltration basins and bio-
retention sites for stormwater management. Included with this memorandum are copies of relevant portions of the
USGS Topographic Quadrangles-Bunyan and Washington with the locations of the piezometers identified.
Piezometer locations were fixed in the field using a hand held CPS device. The general locations of the piezometer
locations are also shown on the enclosed site plan.
According to the USDA Soil Conservation Service (SCS) Soil Survey of Beaufort County, the upland soils at the site
are a mixture ol'Ahavista (AaA), Seabrook (Sb) and Tarboro (TaB) with Portsmouth (PI) soils dominant in the
wetland areas. Soil types were not confirmed as part of This study.
According to the SCS Soil Survey, the permeability rates expected in Altavista soils at depths from one to five feet
• below existing ground surface range from 0.6 to 2.0 inches per hour. According to the SCS Survey, the permeability
rates expected in the Seabrook soils at depths from one to five feet below existing ground surface range from 6.0 to
20 inches per hour. According to the SCS survey, the permeability rates expected in Tarboro soils at depths from
one to five feet below existing ground surface range from 6.0 inches to greater Than 20 inches per hour.
16 shallow piezometers were installed to depths of approximately 6 feet bgs. The locations were selected based on
the proposed locations of stormwater infiltration basins associated with the Griffins Beach PUD Subdivision. Boring
logs have been included as an attachment to this memorandum.
In general, soils across the site varied slightly with some noticeable differences. Most noticeable was the occurrence
of'peaty sands and preserved wood encountered in the borings installed in the north and northeast of the site (#1002,
# 1008, # 1009 and # 1010). Upland soils profiles across the site can be summarized as twelve inches of fine dry
sands (ranging in color from light brown to black) overlying silty to sandy clays (ranging in color from pale brown to
red or yellow brown wtih varying degrees of iron oxidation) to depths of three or four feet below ground surface
(bgs). AI depths of around three to four feet bgs, medium to coarse sands were reported (ranging in color from pale
brown to red and yellow to blue grey). A detailed soil lithology of cash piezometer installed was recorded along
with a depth to water measurement and seasonal highwater estimate. A copy of the boring log for each location has
been included with This memorandum.
Hydraulic conductivity was calculated by performing a slug test in each well. The slug tests were performed by
measuring the rate at which water returns to the piezometer after removing a "slug" of water with it standard
polyethylene bailer. Depths to water were recorded manually al predetermined intervals using a water level meter
until a minimum of 75 percent of the well volume had returned. Data was then entered into the Aqtesolv® Software
which calculates hydraulic conductivity using the Bouwer and Rice unconfined aquifer solution. The data and
results of the slug tests and Aqtesolv@ software print sheets has been attached with this memorandum. A table
summarizing the depth to water, estimated seasonal high water table and hydraulic conductivity of each of the
® piezometers has been attached to this memorandum.

Based on the data collected on June 21-24, 2008 it would appear that sm-ficial soils on site exhibit varying
infiltration rates ranging from 0.216 inches per hour to greater than ten inches per hour. These rates are more
conservative than the published rates found in the SCS Soil Survey of Beaufort County. Please note, these tests were
conducted by hand. 'therefore, the initial recharge in the piezometers after the slug of water was removed has been
lost. This skews the results to a more conservative estimate. Generally, the upland soils on site are sandy with minor
silts at three to four feet bgs. In those areas near the river expect reduced grain size and perhaps better sorting which
may explain slower infiltration rates. There are also several portions of the site -most notable along the northeast
corner that have heavily organic sands and large chunks of wood at depth. Substantial pieces of preserved wood
were encountered below the water table in Piezometer locations #1002, # 1008, #1009 and # 1010 and should be
accounted for accordingly in the development plans.

Notes:
I. Depths to water measured from ground surface on June 24, 2008. All depths in feet.
2. Seasonal High Water Table Estimates based on indicators in soils (e.g. oxidation, gleyed coloration etc...)
3. Hydraulic Conductivity determined using slug test data entered in Aqtesolv® Software solving for K with the
unconfined Bouwer-Rice solution.
4. Not able to be determined based on amount of organic sands and lack of oxidation. Possible voids in near
proximity of boring based on presence of preserved wood and organic material.
5. Potential aberrant test. Large quantities of preserved wood at water table surface and below locally restricting
Groundwater recharge.
6. Piezometer installed closest to Pamlico River. Relatively slow recharge may be an indication of sorting or
reduced grain size locally influenced by deposition along river.
