Dear Dr. Williamson:
The Wilmington Regional Office received a Stormwater Management General Permit application for the, laiid
clearing activities in Section 2, Tracts 1 & 2 of Ocean Isle West Destination Resort on February 22, 1999. Staff review
of the information provided has determined that the proposed clearing activity does not meet the definition of
development and is therefore exempt from the requirement to submit a Stormwater Management Permit application
at this time, as provided for in NCAC 2H.1000. Enclosed please find the submitted plans, application and check for
$50.00.
The project was issued a Stormwater Management Permit for the master plan development of this site. It is
not necessary to submit for a general stormwater permit for each section or tract individually. The development is
already covered by the master plan permit. Additionally, the fee for all projects is now $420.00, regardless of the type
of project, including generals.
If at any time in the future, development of the site is modified from what was approved, you must apply for
and receive a Stormwater Management Permit modification. If you have any questions concerning this matter, please
do not hesitate to call me at (910) 395-3900.

Dear . wis:
In accordance with our conversation on Wednesday, May 19, 1999,1 wanted to send this
letter to ensure our understanding of our conversation was consistent with one another.
As I explained, the subject project has undergone some minor changes since the
issuance of the stormwater permit on November 6, 1998. These changes are related to
property ownership and minor changes in layout and residential product types. Due to
different timetables for development and different development styles, Ms. LaDane
Williamson and Dr. DeCarol Williamson have divided the property. This division has
enabled each to develop plans in their respective style and timetable.
There have been some minor changes to each owner's Master Plan and we have spent
considerable time with the Town of Ocean Isle Beach's Planning Board and Town Board
approval process. Through this process, we have had some density reduction and some
reconfiguration of product type and location. I anticipate that these changes will not be
an impediment to obtaining your approval for a revised stormwater plan.
The primary issue that we discussed was whether there would be any reasons or
difficulties associated with a request to have each respective party obtain their own
individual stormwater permit. As we discussed, this would require each respective
party to prepare their new stormwater management plan for their revised master plan.
Each respective party will need to submit appropriate documentation to enable issuance
of a stormwater permit for their project. This submittal must be similar to the
application package (completed application, processing fee, stormwater plan schematics
/ details, supporting calculations, etc... ) submitted for the original stormwater permit
issuance. This would enable each party to develop and manage their property
independent of the other. As you can understand, this will enable us to handle our
regulatory affairs without affecting or inconveniencing the other and also minimize any
confusion with your office.

I hope that this letter suffices as an overview of our discussions. Unless I receive a
telephone call or a letter to the contrary, I will consider this letter as an acceptable
understanding that the previously issued stormwater permit can be split and reissued to
the two separate parties for their respective projects. Each party is anxious to proceed
with development activities and will be submitting detailed information for their
respective project's first phase in the near future. If this does not create too much
confusion, we ask that we be allowed to make such applications simultaneously with
these requests for separating the stormwater permit.
If additional clarification is necessary, please do not hesitate to contact me at (910) 579-
0733. If you have any questions related directly to Dr. DeCarol Williamson's portion of
the project, please contact Mr. Alan Lewis, East Coast Engineering, at (910) 754-8029.

Request for Stormwater Exemption
Dear Ms. Lewis:
This is to inform you that we are making application to the Land Quality Section for an erosion
control permit for the subject project. Your February 23, 1999 letter to Dr. DeCarol Williamson
relative to our submittal for the former "Tracts 1 and 2" project established DWQ's position that
"the proposed clearing activity does not meet the definition of development and is therefore exempt
from the requirement to submit a Stormwater Management Permit application at this time...". The
enclosed Erosion Control Plans illustrate that the type work proposed for the current "Tract 3"
project is the same as the type work proposed for the former "Tracts 1 and 2" project. We therefor
request an exemption from the requirement to submit a Stormwater Management Permit application
for the current project.
Your attention to this matter is appreciated. Please give us a call if you have any questions or
comments.

Revised Stormwater Master Plan Submittal
Dear Ms. Lewis:
We have revised the subject stormwater plan based on the comments presented in
your July 1.5, 1998 and July 23, 1998 letters to us. The revisions are summarized below,
and are numbered to correspond to your numbered comments.
L A new page 3 of the application has been prepared and signed by the owners.
2. Page 2 of the application has been revised by designating that the project is within
the Lumber River basin.
3. The "...Stormwater Data Summary" table on Plan Sheet # 2 has been expanded to
include the total BUA for each of the building footprints and other project
components.
4. Sheet # 3 has been added to the plans. This sheet shows preliminary layouts of
22 "engineered" stormwater systems. Of the 22 subbasins, Numbers 17, 18, and
21 are projected to use subsurface infiltration pipe/trench systems and the
remaining subbasins are projected to use dry infiltration basins. At the time of
detail design submittals for the engineered areas, we will demonstrate that all of
the runoff from BUA will be directed to the infiltration basin or pipe/trench
system. This will involve runoff through roadway gutters, swales, or/or
conveyance piping as necessary.
S. (No response required. We appreciate your clarification.)
G. We plan to design the engineered systems such that the runoff from West Second
Street does not enter any of the engineered systems. We also plan to take this
approach for West First Street also, though accomplishing this will be more
difficult. Recognizing the possibility that we may have to treat the runoff from
West First Street, we have shown it (Sheet # 3) as being within engineered
system boundaries. Regardless, the "engineered" systems as submitted are
preliminary. Future detailed designs will account for all BUA which drains to the
systems.

Re: Ocean Isle West Destination Resort
Dear Ms. Lewis:
It is estimated that the subject project will have a build -out period of approximately
10 to 1.5 years. The developers are currently considering two options for obtaining permits
under the stormwater "Rules". Option # 1 involves submitting stormwater applications on
a phase -by -phase basis over the build -out period. Option # 2 involves designing the entire
project "up -front".
Several questions surface when considering the two options. You discussed some
of the questions with Mr. Don Covil of our office on May 1.9. In the interest of clarity and
based on the benefits of a having a written record, we would appreciate a letter from you
addressing the following issues.
• The developers would prefer Option # 1 if approval of the Master Stormwater Plan
"locked" the project into the current "Rules". They would not have to be concerned
about possible future Rule changes which could significantly impact future phases.
The basic question here is:
To what extent does the date of approval of the Master Stormwater Plan affect
the review criteria for subsequent stormwater submittals for component "high
density" phases?
• If the developers chose Option # 2 they would need to have some degree of
"comfort" that the permit would be valid even if construction of a particular phase
was initiated 20 years into the future. The basic question here is:
Are stormwater permits valid indefinitely, or at least within the time span of
current interest (10 to 15 years)?
It is likely that many of the future phases will take on at least minor modifications
over time. The developers are concerned that if Option # 2 is selected, the State
may determine that even minor modifications provide reason for invalidating
existing permits in the interest of exercising more stringent controls. The basic
question here is:
Ms. Lewis Page 2 Ocean Isle West
May 21, 1998 Destination Resort SW
Assuming the answer to the previous question is yes, what degree of
modifications would be considered grounds for invalidating an existing permit?
We realize that these questions may be difficult to answer; however, we would
appreciate any help you could give us that may be of benefit in making this important
decision. Please do not let these questions interfere with the current Master Plan
submittal/review/approval process.
Thank you for your continued assistance on this project. We look forward to
hearing from you at your earliest convenience.

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980345
Ocean Isle West Resort Master Plan
Brunswick County
Dear Mr. Covil:
The Wilmington Regional Office received a Stormwater Management Permit Application for Ocean
Isle West Resort on May 18, 1998. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the stormwater review:
1. The signature page 3 of 4 of the application is unreadable. Please provide a readable, original
signed page.
2. This project is within the Lumber River Basin. Please correct this in Section III, item #2 on
page 2 of the application.
3. Please add the total BUA to the drawings submitted for each of the footprints.provided, ie.,
townhome, condominium, restaurant, beach club, and retail/spa.
4. Please indicate the method by which the high density portions of the project will be treated,
and provide preliminary calculations of the design. Additinally, the pond and/or infiltration
areas need to be located in detail on the plan, ie., contours, labelling permanent pool and
design pool elevations, outlet structure, etc. I know we discussed the use of the existing
lagoons as stormwater treatment devices, but the discharge from the lagoons would have to
be directed toward the ocean due to the classification of the Eastern Channel as SA.
Engineered solutions are limited to infiltration, if the system drains to SA waters. Only
sheetflow and infiltration have been noted as the treatment devices on the application.

Stormwater Project No. SW8 980345
5: Per the Central Office, the approval of a master plan does not preclude the developer from
having to meet the intent of the rules in effect at the time of future plan revisions. Minor
modifications such as relocation of BUA within the project (or phase in this case) would not
invalidate the existing permit. Permit modificaions would be triggered by changing the BUA
(adding more to a phase) or by design changes to the control systems.
6. Even though West First Street and West Second Street are existing, if drainage from any parts
of them cannot be routed around a proposed engineered system, then the system must be sized
for it.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to August 15, 1998, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.

Revised Stormwater Master Plan Submittal
Dear Ms. Lewis:
4918 Main Street
Post Office Box 2869
Shallotte, NC 28459
We have revised the subject stormwater plan based on the comments presented in
your August 17, 1998. The revisions are summarized below, and are numbered to
correspond to your numbered comments.
1. The percent built -upon area has been replaced with total built -upon area (SF) in
each of the infiltration systems data tables on Plan Sheet # 3.
2. Surface area of basin (trench) bottom has been added to each of the infiltration
systems data tables on Plan Sheet # 3.
3. A column for total volume required and provided per basin (trench) has been
added to each of the infiltration systems data tables on Plan Sheet # 3.
4. A column for the seasonal high water table elevation has been added to each of the
infiltration systems data tables on Plan Sheet # 3.
5. A column for the lowest allowable bottom elevation has been added to each of the
infiltration systems data tables on Plan Sheet # 3.
6. A column for anticipated storage depth has been added to the infiltration basin
data table on Plan Sheet # 3.
7. The pipe length presented in the infiltration pipe/trench data table of Plan Sheet #
3 has been replaced with a column labeled "length of 6' X 2' gravel trench with
24" perforated pipe". Revised lengths are provided based on storage in the pipe
and within the pores of the gravel. A trench detail has also been added to Plan
Sheet # 3.

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980345
Ocean Isle West Master Plan
Brunswick County
Dear Mr. Safrit:
The Wilmington Regional Office received previously requested information from East Coast
Engineering for the Stormwater Management Permit Application for Ocean Isle West on August 27, 1998.
A preliminary review of that information has determined that the application is not complete. The following
information is needed to continue the Stormwater review:
More than half of the infiltration areas have proposed bottom elevations above the existing
grade, and will require that fill material be placed in order to achieve the required 2'
separation. The ability to allow this will need to be confirmed on a case -by -case basis by the
Regional Soil Scientist. The Master Plan permit must include a condition to this effect, and
will require that in those areas that fill cannot be used, the project area must either revert to
low density, or the runoff must be collected to another basin.
2. Do the outlines shown on the plan for the infiltration areas represent the bottom elevations or
the top?
3. A signed Oeration and Maintenance Plan
4. Provide a vegetated filter detail for the bypass flows. Due to the SA class waters, direct
discharges are not allowed, so filter design becomes very important. No channels are allowed
to be graded into SA waters, therefore, the filter must be constructed in such a way that the
runoff is dispersed evenly in a flow spreader mechanism and allowe to sheet flow over at least
a 50' long area of natural, grass covered ground.
5. Provide preliminary trench locations.

6. Provide the built -upon area per lot limit for the single family lots on page 4 of 4 of the
application.
7. Provide a copy of the soils report indicating the type of soil, expected infiltration rate, and
Seasonal High Water Table elevations.
8. Please calculate the anticipated drawdown time in each system.
9. The project is no longer low density,.with a built -upon area proposed of 38.8%. Please submit
the additional $160.00 engineered system application fee.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to November 23, 1998, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the
permit.
If you have any questions concerning this matter please feel free to call me at {910) 395-3900.

Stormwater management permits shall be issued to the developer or
owner and shall cover the entire master plan of the project
("stormwater master plan permit"). The master plan permit shall
include specifications for stormwater management measures associated
with each individual lot or property within the project.

What would the trigger mechanism be to get a submittal of the specific
design for review prior to construction?

My personal opinion is that the master plan must demonstrate some
forethought for how stormwater will be handled or your just going to
have more headaches later on. Therefore, the master plan should
designate the general vicinity and types of stormwater control
system(s) under consideration.

Dear Ms. Lewis:
Please find enclosed the following documents which constitute stormwater
submittals for the subject projects:
1. Two copies of Stormwater Master Plan Sheets 1 and 2;
2. One original and one copy of the Stormwater Management Application Fonn
representing a "General Permit" application for the Stormwater Master Plan;
3. One original and one copy of the Stormwater Management Application Form
representing a "Low Density Permit" application for Phases C, D, and F;
4. One copy of the Low Density Supplement to the stormwater application for Phases
C, D, and F; and,
5. Check in the amount of $225 to cover the application fee for the low density
projects.
6. One set of dimensioned footprints illustrating the built -upon area for rnulti-family
residential structures (townhomes, duplexes, triplexes, small sixplexes, large
sixplexes, and 12-unit condos). As noted on Plan Sheet 4 1, the built -upon areas
for commercial structures are based on conceptual footprints. The footprints of the
buildings that will actually be constructed will be reflected in the stormwater plans
for the particular phase(s) of interest at the time of engineered solution project
submittal.
The Stormwater Master Plan will be updated each time an additional phase or
Phases are "designed" and submitted for stormwater approval. We believe that this is in
keeping with the discussions we have had regarding this project. Should you require
additional information, or have any questions or concerns, please inform us as soon as
possible.

major permit to apply for and receive a Stormwater Management Permit by the Division of Water
Quality. Any construction on the subject site, prior to receipt of the required permit, will constitute a
violation of 15A NCAC 2H.1000 and may result in appropriate enforcement action by this Office.
Either a Stormwater Permit Application Package including 2 sets of plans, completed
application form, fee, and supporting documentation, or a written response regarding the status of
this project and the expected submittal date must be received in this Office no later than April 27,
1998, or the subject project file will be closed and construction may experience a subsequent delay.
Please reference the Project Number above on all correspondence. If you have any questions,
please call me at (910)-395-3900.

DIVISION OF
COASTAL. MANAGEMENT
Ocean Isle West Destination Resort is the vision of LaDane and DeCarol Williamson.
Their goal is to provide Ocean Isle Beach, NC with an upscale residential community with
commercial facilities conveniently located nearby. The project has been professionally
planned with much thought given to quality of life and attention to detail while maintaining a
strict adherence to environmental issues and concerns. Emphasis is made in order to provide
an attractive and secluded project that will promote mainly pedestrian use and less vehicular
travel.
The project is located in a commercial zoning district (Cl) which encourages such
Planned Unit Developments as Ocean Isle West. The project has been approved by the Town
of Ocean Isle Planning Board and the Town Board of Commissioners. The project conforms in
all respects to the Town of Ocean Isle Beach's Planned Unit Development and Zoning
Ordinances as well as the Town's current Land Use Plan. In order to provide desired open
space, much more separation between buildings has been provided than is required by Town
ordinances. In all instances, the Town's maximum building height of 55' is maintained, while
the vast majority of the buildings will be substantially lower than the maximum height limit.
The method of construction for this project will be by conventional equipment. No
special construction equipment will be required. Property and adjacent estuaries will be
protected by construction through the-- implementation of standard Sedimentation and
Erosion Control measures. No construction will occur seaward of the landward toe (heel) of
the oceanfront frontal dune. The construction of small structures will be landward of the
required 60-foot setback limit. Large structures will also adhere to the required 120-foot
setback limit.
In addition to increasing building separation, Ocean Isle West has been planned in
order to reduce impervious surfaces substantially when compared to existing development
areas. In residential areas, all parking is located under the respective buildings while much of
the commercial parking is also located under buildings. Existing freshwater lagoons will be
enlarged and connected in order to facilitate better stormwater management. In addition,
lagoon habitat islands will be constructed as part of the lagoon expansions in order to provide
natural havens for various types of wildlife. Aquatic plants will line the Iagoon edges providing
further benefits as well as serving as simple yet attractive natural buffers and screenings.
AIso, the lagoons will capture all excess stormwater runoff from impervious surfaces after the
initial runoff has been intercepted by specially designed collection, storage and treatment
facilities. Portions of the project will even qualify for low density stormwater designs since
they will contain less than 25% impervious surfaces.
Public ocean access is provided through the use of access easements conveniently
located. While the Town requires ocean access points at least every 1000 feet spacing, this
project provides public access points at least every 500 feet spacing. All off peak commercial
parking spaces are intended to encourage public use and to provide much needed parking by
day visitors.

OCEAN ISLE WEST RESORT - SOIIIHYDROLOGY STUDY
3
Land Management Group, Inc. evaluated a parcel of land owned by LaDane and
• DeCarol Williamson, OCE-an Isle Beach, NC for suitability for stormwater runoff
disposal. North Carolina Department of Environmental, Health and Natural
Resources, Division of Environmental Management regulations (15 NCAC 2H .1008)
were used as guidelines in this evaluation.
•
The tract is bounded on the north side by the Intracoastal Waterway and on the south
side by SR 1144 and the Atlantic Ocean. It is bordered by a residential lots to the
east and west. The site presently contains no structures and is shown in Figure One.
•
The proposed stormwater plan will utilize an infiltration system as described under
Section 15A NCAC 2H .1008 (d) and meeting all requirements of this section. Item
(6) states "that soils must have a minimum hydraulic conductivity of 0.52 inches per
hour to be suitable for infiltration." Item (7) states that "Infiltration system must not be
sited on or in fill material, unless approved on a case -by -case basis under Paragraph
(h) of the Rule." Current design of the proposed will require the placement of fill on
some of the infiltration sites to meet the minimum separation to the seasonal high
water table.
•
The specific purpose of this study was to assess the soil characteristics and physical
properties of the 1) infiltration sites and 2) the soil material to be taken from the
excavation areas. Water cable monitoring during the winter season, soil borings and
• soil pits and hydraulic conductivity measurements have all been used to characterize
the natural soil material and the fill material which is to be excavated and placed
under the infiltration sites.
•
METHODOLOGY
Figure Two shows the locations of the excavation and infiltration borings installed in
• September, 1998. Borings consisted of open unlined bore holes installed using a
standard three and one-half inch soil auger to the shallow water table. Soil pits
examined soil profiles to a depth of eight feet but due to extremely unstable sidewalls,
only minimal soil profile data was collected below the existing water table. Soil
characteristics noted included horizons, depth, color, texture, transient water table, and
observed water tables.
•
•
OCEAN ISLE WEST RESORT - SOI!JHYDROLOGY STUDY
• Figure Three shows the location of water level monitoring wells installed in January,
1998. Standard auger descriptions were collected and WL40 water level monitoring
wells were installed to track vertical fluctuations in soil water. Depth to water was
determined using horizontal and vertical control on all borings provided by Tompkins
Surveying. We also collected rainfall data using a continuous WL20 rain gauge.
•
We utilized a regression statistic and ANOVA table to evaluate the water table and
elevation data set.
• Direct measurement of Soil Permeability using the shallow well pump -out test
C7
(Boersma, 1956). Shallow soil borings and analysis were performed according to
"Methods of Soil Analysis;" until steady-state equilibrium was achieved. Saturated
hydraulic conductivity or "Ksat" was computed using the following equation:
a
Ksat.--{4.63 r21[y(H + 10r)(2=y1H)]}(delta yldelta t).
Following purging of the wells, we measured permeability three times on the heaviest
horizon in five of the borings.
a DATA
Seasonal High Water Table:
The depth to the seasonal high water table is derived using a combination of empirical
and interpretive parameters. The measured data uses the water table monitoring
results and the appropriate rainfall analysis.
Appendix A shows the graph of the daily rainfall totals beginning in late December,
1997. Historical rainfall tc!4als by month were obtained from the North Carolina
Climatological Center, Raleigh, NC for Ocean Isle Beach, NC. Calculation of the
median quartiles allows fcr determination of normal rainfall conditions, as represented
by the two, bold lines.
Assessment of groundwater levels should be conducted when rainfall is within the
normal range. This corresponds to the period from January 2 through February 2,
1998. Appendix B shows the graphs of each well shown in Figure Three.
Corresponding statistics fcr the water levels during this period are also shown on each
• graph. Mean values are used to describe the depth to seasonal high water table.
C
OCEAN ISLE WEST RESORT - SOILIHYDROLOGY STUDY 5
Using the soil profile data collected in the monitoring wells and the soil borings and
pits we mapped the site using three groupings. Figure Four shows the grouping
across the site in twelve -inch increments. Small inclusions may exist within any given
delineation but are not large enough to map out.
9 Soil Physical Properties:
•
Physical characteristics are given in Appendix C for the soil borings and excavation
pits. Physical characteristics are given in Appendix D for the monitoring wells.
Statistical analysis shows good correlation of predicted seasonal high water table
elevation based on ground elevation. Appendix E shows the input data and the
computed test statistic for the regression. From this analysis, on this landscape,
seasonal water table elevation is predicted by the following equation:
D = 2.3 ft + 0.3(E),
where D is the predicted elevation of the normal seasonal high water
table and
E is the ground surface elevation.
Individual points for infiltrations basins can now utilize this equation to derive the
predicted level of the seasonal high water table.
40 Other physical characteristics from Appendices C and D are the texture and structure.
Virtually all sites have coarse, rounded sand with less than ten percent coarse
fragments in the profiles. This sediments have extremely high permeabilities.
. Results -of the K,,, determinations --and' statistical calculations are given In Appendix F.
The results of the tests show all locations to have permeabilities of 14.25 inches/hour
or greater for all replications for all sites.
DISCUSSION
•
The existing soil and fill is highly permeable and is fairly uniform across the site. The
natural soil is sandy as most barrier islands are. Existing fill on this tract is at least 15
years old according to existing aerial photographs.
•
The soil material in the areas of the soil pits is to be used during construction for the

elevation of the bottom of the infiltration basin to meet the two foot minimum to the
seasonal high water table. Permeability of this material is 14.25 inch/hour or greater
and should not change substantially during excavation and shaping_ Water table data
is predictable for any given site using the equation:
D = 2.3 ft + 0.3(E),
where D is the predicted elevation of the normal seasonal high water
table and
E is the ground surface elevation.
•
This allows the design of individual systems using material excavated onsite.
