Dear Mr. Moore:
Please find enclosed two copies of revised drawing C8 for the Inn at Hatteras
Village. We have revised the overflow structure detail to match the proposed
elevations and configuration of the infiltration pond. Please replace the
originally submitted sheet C8 with this revised sheet.
If you have any questions or require additional information, please don't
hesitate to call.
sincerely,

Della,
I was able to look back into our files and found where I had sent a copy of the original design certification
of the stormwater system by Bill Gilbert, P.E., dated 6127/06, to AI Hodge via fax on 3/20/06.
We also sent a copy of the certification to Mr. Tom Lyon of Tidewater Hotels & Resorts to be attached with
the renewal form. After reviewing the file, my recollection is that Tidewater Hotels & Resorts were to
execute the renewal form, pay the fee and attach the original copy of the engineer's certification.
I will check into the status of this renewal form and let you know what I find out.
Sincerely,
Quible & Associates, P.C.

Subject: Stormwater Permit No. SW 7951008
Inn at Hatteras Village
Dare
Dear Dwight Wheless,
The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW 7951008
to Tidewater Inn Management for Inn at Hatteras Village on 12/11/1995. This permit expires on
12/11/2005. Section .1003(h) of 15 A NCAC 2H .1000 (the stormwater rules) requires that applications
for permit renewals shall be submitted 180 days prior to the expiration of a permit and must be
accompanied by a processing fee,.which is currently set at $420.00. If this is still an active project
please complete and submit the enclosed renewal application in a timely manner. If this project has not
been constructed and a permit is no longer needed, please submit a request to have the permit
rescinded. If you have sold the project, or are no longer the permittee, please provide the name, mailing
address and phone number of the person or entity that is now responsible for this permit. Enclosed is a
form for change of ownership, which should be completed and submitted if the property has changed
hands.
Your permit requires that upon completion of construction and prior to operation of the permitted
treatment units a certification of completion be submitted to the Division from an appropriate designer
for the system installed. This is to certify that the permitted facility has been installed in accordance with
the permit, the approved plans, specifications and supporting documentation. Please include a copy of
the certification with your permit renewal request and processing fee. Enclosed is a copy of a sample
certification.
You should be aware that failure to provide the Designer's Certification and the operation of a
stormwater treatment facility without a valid permit, are violations of NC General Statute 143-215.1 and
may result in appropriate enforcement action including the assessment of civil penalties of up to
$10,000 per day.
If you have any questions, please feel free to contact me or a member of the coastal stormwater staff with
DWQ at 252-946-6481.

Gentlemen,
I received a phone call from Della Robbins of the NCDE&NR, DWQ, regarding the renewal of the
Stormwater Permit for the Villas of Hatteras Landing,
In March of 2006, we faxed a copy of the original engineer's certification by Bill Gilbert, Iil, P.E., to Al
Hodge of the DWQ and to Tom Lyon. The original certification must be attached to the permit renewal
application. It was our understanding that the renewal application would be executed by Tom's staff, the
renewal fee paid by the owners and the renewal application would be sent to the DWQ, directly from
TWH&R. DWQ has not received the renewal application.
If we can be of any assistance in the preparation of this renewal application, please let us know.
Sincerely,
Quible & Associates, P.C.

Della,
I was able to look back into our files and found where I had sent a copy of the original design certification
of the stormwater system by Bill Gilbert, P.E., dated 6/27/06, to A! Hodge via fax on 3/20/06.
We also sent a copy of the certification to Mr. Tom Lyon of Tidewater Hotels & Resorts to be attached with
the renewal form. After reviewing the file, my recollection is that Tidewater Hotels & Resorts were to
execute the renewal form, pay the fee and attach the original copy of the engineer's certification.
I will check into the status of this renewal form and let you know what I find out.

Re: Stormwater Management Plan for The Inn at Hatteras Village, located in
Hatteras Village, Dare county, North Carolina
Dear Mr. Moore:
Please find enclosed two copies of Drawings 1 (Cover Sheet), 2 (Site Plan), 3
(Grading and Drainage Plan) and 8 (Stormwater Drainage Details) that detail
the stormwater management plan for the project. Also enclosed is a North
Carolina stormwater Management Permit Application and an application fee check
for $385.00.
The Inn at Hatteras Landing will consist of a 72 room hotel with a 2 bedroom
employee apartment. A total of 112 parking spaces are proposed to service the
facility. storm flows from the parking and landscaped areas will be directed,
via surface flows, to the retention pond. Storm flows from the roof areas of
the hotel and the pool decks will be collected in storm drainage pipes and
piped to the retention pond. site coverage calculations, as shown on the
Grading and Drainage Plan, are summarized below:

The retention pond was sized to hold, at a minimum, the first 1 1/2" of rain.
Total retention requirements for a 1 1/2" rainfall is calculated as follows:
A x D = V where
A = area of impervious surface in square feet
D = depth of 1 1/2" in feet (.1251)
V = required storage in cubic feet
A x D = V
75,851 SF x 0.125=(9,481 CF
The retention pond's storage capacity at the permanent pool elevation (6.00)
is calculated by computing the average area between the 5' and 61, then
multiplying by the pond depth of 1.00 feet. The storage volume (V) at the
permanent pool elevation is computed by the following:
V = (Area (at 5' contour) + Area (at 6' contour))/2 x depth
V = (8,900 + 10,149/2) x 1
V = 9,524 CF
Total storage required "=-_9481 CF
Total storage provided (at permanent pool elev.) �524 CF
The invert on the pond overflow structure, as indicated on the drawings, is
set at elevation 6.75. This will allow for a total pond -storage capacity of
-177521 CF. The total pond storage capacity is calculated as follows:
V = (Area (at 5' contour) + Area (at 6.75' contour))/2 x depth
V = (8,900 + 11,124/2) x 1.75
� 1�7, 521 CF
Total pond storage capacity (17,521 CF) minus required storage capacity (9,524
CF) equals 7,997 CF of excess storage capacity. This equates to an additional
ri—.26" of rainfall on the impervious surfaces that will be retained on -site.
Due to this extra storage volume (total storage is approximately twice the
required volume) and the high infiltration rate and hydraulic conductivity of
the soils, we are not proposing a "bypass" system for the runoff above the
first 1 1/2" of rainfall. Once the stormwater exits the pond, the stormwater
will surface flow along a 30, vegetated buffer before reaching the adjacent
wetlands.
Also enclosed with this application is copy of the text portion of a Hydraulic
Soil Report done by Soil & Environmental Consultants, Inc. dated March 1,
1991, revised October 4, 1995. This report addresses the soil characteristics
and water table depth. A memorandum from Joe Lassiter of our firm is also
included which addresses his findings of water table depth.
If you have any questions or require additional information, please don't
hesitate to call.

HYDRAULIC CHARACTERISTICS OF THE SOILS
AND SHALLOW AQUIFER AT THE
PROPOSED HATTERAS LANDING PROJECT
DARE COUNTY, NORTH CAROLINA
March 1,1991
Revised October 4,1995
On November 15,16,17 and 18, 1990, Mr. Kevin Martin (Certified Professional
Soil Scientist) and James Beeson evaluated the hydraulic characteristics of the
soils and shallow unconfined aquifer on the property. The property is located
adjacent to the Hatteras Ferry and NC Hwy. 12. The purpose of this evaluation
was to determine the hydraulic conductivity of the saturated zone and
transmissivity of the shallow unconfined aquifer so that this data could be used
to determine potential mounding beneath an on -site subsurface wastewater
treatment system. The system is expected to receive 21,700 gallons per day of
sewage effluent. The following is a brief report of the methods utilized in this
evaluation and the results obtained. There will actually be two different systems
serving two different facilities, but due to their proximity we have treated them
as one system for the purpose of this report
Soil Descriptions
Soil auger borings were made to identify soil textures and to determine if
restrictive horizons occur on the site. Borings were performed at the locations
shown on the attached blue prints, Descriptions are attached in Appendix 1 of
this report for each boring site in the form of hard -written logs. Soils
in the areas examined have sandy bextures. Such soils can be permitted for
conventional septic systems by the county with a loading rate of .8 to 1.2 gpd/ ft2
on a trench bottom area basis or for a Low Pressure Pipe system with a loading
rate of .4 to .6 gpd/ft2 on an area basis. These loading rates are taken from 10
NCAC 10A.1900 (Laws and Rules for Sanitary Sewage Collection, Treatment and
Disposal). This system will employ Low Pressure distribution.
The area of the proposed system is shown on blue prints provided to you by
Quible & Associates. The potentially "restrictive" layer found on -site by Dr.
Uebler was not found in any other location on -site, this is discussed in more
detail later in this report Soil suitability evaluations as per current DEH

On -Site Waste Treatment Systems, Evaluation and Design
7n 7nHA L9069vesls TZMT QRFUNA/AT
regulations were performed on -site previously by the county health department
and later by Dr. Uebler.
Transmissivity .;
Transmissivity of the saturated zone was determined using a multiple well
drawdown test. One pumping well and six observation wells were used (see
blueprints for well locations). The methods used in these measurements were
similar to those described in Theory of Aquifer Tests, U.S. Geological Survey
Water -Supply Paper 1536-E: pp. 91-100.
Based on our previous experience on predicting mounding, we located the most
restrictive area from a soils and hydraulic standpoint and performed an 8 hour
drawdown test with a constant discharge rate of 4gpm. Measurements were
made as shown in the attached field log (see Appendix 2).
The pumping test was performed in the area where Dr. Uebler and others had
found what might be a restrictive horizon. This horizon was at 5 to 6 feet below
land surface and was made up of a darkly stained sand. It did not appear to be
a "marsh mat" like those commonly found on the Outer Banks beneath'old fill
areas or naturally deposited dunes. Such layers are sometimes present due
to the islands migration toward the mainland during which it migrates over the
sound side marshes containing organic surfaces. The "organic" layers are
usually level bedded (at the same elevation) and act as aquitards.
We actually attempted to use the very same auger hole that Dr. Uebler made at
this site for our pumping well but could not "force" the well down. However,
we then moved over several feet and easily installed a pumping well and four
observation wells 'a little over 6' below land surface (see blueprints for locations).
The potential restrictive'layer was not observed in any of these wells in this area
or in any of the other well borings on the site (for locations see blueprints). This
suggests that the layer encountered was isolated to that one hole and could have
been a partially decomposed log, stump, etc.
The actual measurements, graphs, curve matches and calculations for the pump
test are attached in Appendix 3 of this report. I should that note even though the
aquifer thickness may be as much as 60' to 80' or more we chose to evaluate the
upper. 5 or 6 feet since only the shallow part of the aquifer will respond to the
additions of wastewater even though no restrictive layer is present
The effective transmissivity for the upper 5 feet of the aquifer was determined to
be about 500ft2/d,(see data curves and calculations in Appendix 3 of this report).
This meansthatthe.hydraulic conductivity is about 100ft/day. These numbers
are in the range of{those;normally found in similar areas. If one used the entire -
thickness of the aquifer (about 60') at of 6000ft2/day would result. The lower T
value presented is probably a more appropriate number considering the purpose
of this report because we are dealing with the reaction of the upper part of the
aquifer. This lower value was used in predicting the mounding for the
drainfields.
Boulton type curves were matched with plots of drawdown (ft) versus t/r2 for
two observation wells (TW2 and TW4) which were approximately 5' and 10'
from the pumping well (see blueprints). This was necessary since the test
initially "behaved" as a confined aquifer, passed through a "delayed yield"
phase, and then began to behave.as a unconfined aquifer near the end.
Therefore, this type curve matches are inappropriate. This "switching" in the
"behavior" of the aquifer is commonly observed in barrier island pump tests.
Also attached in Appendix 4 is a Jacob "distance drawdown" graph for
data from the same two wells (TW2 and TW4) and associated calculations which
also resulted in a transmissivity of about 500ft2/d. Using both methods of
analysis of drawdown data serves as a check (i.e. if the two show drastically
different results something is wrong with the analysis or collection of data).
Seasonal High Water Table
Two methods were used to determine the seasonal high position of the water
table. The first employed the use of the "Fetter Water Table Equation" for
predicting water table heights beneath Oceanic islands (reference Applied
Hydrogeology by C.W. Fetter, Jr.,1980, .pages 144-146). The second involved the
installation and monitoring of two monitoring well networks which transected
the island (see blueprints).
The calculations in Appendix 5 for the Fetter Equation show that the predicted
average position of the water table in the center of the island would be about
1.06 feet above the level in the sound. This predicted average position is lower
than the actual water level observations made on -site, which suggests that our
measurements were made during a period of above normal water table levels.
Because the measurements are not drastically higher than predicted
average position of the water table, this supports the other evidence that there is
not a restrictive horizon beneath the proposed drainfiield area.
Water level observations and. fluctuation are shown in tabular form in Appendix
6 of this report and graphically on the attached blueprints. Also attached are
readings on 'the tide gauges which reflect tidal fluctuations and cwn be compared
to water levels in the monitoring wells with respect to time.
In general, the water levels in the wells did not respond to fluctuations in tidal
levels during a 36 hour observation period with the exception of well #8 which
was installed in the edge of a tidally flooded marsh. In fact, while the tide
constantly rose due to a 20 to 30 mph constant wind from the northeast, many of
the wells dropped slightly over time. This along with the data collected from the
wells on 11/30/90 by Quible & Associates (see Appendix 6 and blueprints)
tends to indicate that little tidal effect exists beneath the proposed drainfiield.
It is interesting to note that when the 11/30/90 Quible data is plotted graphically
verses our data from 11/15/90 a distinct pattern appears (see blueprints). Our
data shows a constant water level slope from the primary dunes toward the
sound while the Quible data indicates the expected normal shape of the water
table beneath the island (i.e. higher in the center and sloping both toward the
sound and the ocean). This suggests that our readings were made shortly after a
significant rainfall event since the levels are highest in elevation beneath the
areas with the thickest unsaturated zone (i.e. the dunes). A copy of the
Hatteras rainfall records indicates that a 24 hour rainfall event of 3" occurred a
week before our work on November 9 and 10,1990 (see Appendix 7).
It should be noted that due to the nature of the uncoated sands in these areas the
seasonal high position of the water table cannot be determined by the evaluation
of soil color. It must be examined during expected high positions. The'water
levels observed on -site should be assumed'to be seasonal high positions since
these measurements were taken in early winter when evapotranspiration is low,
one week after a 3" rainfall event and before, during and after a 20-30 mph
strong northeast wind which caused the water level in the sound to stand
constantly at a level of 1 to 1.5' above normal for 24 to 36 hours. Due to the close
proximity of the site to the sound and recent weather conditions in the area prior
to and during our measurements, we believe they are a good approximation of
the seasonal high stand of the water table. However, to again be conservative, in
our recommendations based on our mounding model, we allow for .2' rise above
and the levels observed and the mounding predicted when determining
minimum elevation required to maintain minimum separation between trench
bottoms and the water table.
Mounding
Using the measured values described above and using the inputs shown on
Table 1, various approaches were made to predict the mound which would
develop under the system(s). The systems were assumed to be rectangular for
the purposes of the model, but total square footage of drainfield is
approximately equal to that proposed. Several different scenarios were
examined, but only the most realistic will be discussed in this report In all cases
it was assumed that only the upper 5 to 6 feet of the aquifer responded and that
the water table remained at its seasonal high position year round.

The computer model used for predicting mounding beneath a rectangular basin
with a constant recharge rate was version 3.0 of the Colorado State University
Program CSUPAW Well and Pit This program was developed by D. Moulden,
D. Sunada and J. Warner. A journal article describing the program was
published in Groundwater Vol. 22, Number 1, Jan -Feb 1984. The
microcomputer uses Glover's Solution with consideration for Hantush's better
means of evaluating this solution by integration by parts. The Division of
Environmental Management, Groundwater Section often uses this model to
predict mounding beneath large on -site wastewater systems and for stormwater
infiltration basins.
The proposed layout of active and repair areas shown on the blue prints
submitted by Quible Associates dated 9/21/95, shows an alternation of system
and repair areas. This will tend to minimize mounding as compared to
concentrating all of the system in one area, so this approach is recommended.
However for the'sake of modelling mounding beneath the systems we chose to
use a scenario where Field 2A, Repair 2A, Field 2B and Repair 2B were treated as
one active drainfield. The mounding predicted by such treatment will be
somewhat worse than that which will actually occur utilizing the alternating
system and repair design proposed. Therefore, like all other assumptions in this
report, this is a conservative approach Repair Area 1D, Field 1D, Repair Area
1C and Field 1C is also modelled, but is treated as an independent system due to
its distance from Field 2A and 2B. We believe this approach best reflects the
proposed wastewater application methodology on -site...
Figure 1. shows the resultant mound developed beneath Field 2A, Repair 2A,
Field 2B and Repair 2B and at steady state after 3 years of daily application of
.5gpd/ft2 (13,020gpd over 26,040ft2). This graph shows that a mound would
develop 1.0' above the existing water table.
The mounding beneath Repair 1D, Field 1D, Repair 1C and Field 1C is shown in
Figure 2. Figure 2 assumes a .5gpd/ft2 loading rate (8,903gpd over 17,805ft2)
and indicates that a mound would develop to a maximum height 1.3' above the
existing water table.
Conclusions and Recommendations
Based on the findings stated above the following treatment for the drainfields is
suggested:
A.
The state requires a separation of 2' between the trench bottom and
the predicted mound height for all drainfields. Assuming a trench
depth of 12" (6" cover and 6" gravel), the proposed drainfields in
Active Areas 2A, 2B, 2C and 2D should be brought up to a uniform
elevation of at least 7.0'. To round these numbers off and allow for
an on "safety Iactor" it would be simpler to bring the land
surfice elevations up to 7.51.
Similarly Field 1A, 1B, 1C and 1D should be brought up to a
uniform landsurface elevation of at least 7.3.
These final elevations were determined using our predicted "high"
water table elevation of 2.8' above MSL, adding the 0.2' "safety
factor" for natural water rise, adding the predicted mound height
adding the 2' separation from the trench bottom and adding 1' to
allow for installation of an LPP trench.
B. The original elevations across the proposed system areas varied
and contained areas well above' 8' MSL, so it was possible to "even"
the proposed drainfield areas out to the recommended elevations.
Attempting to install a system in the original topography would be
difficult and would likely result in ("seepage") effluent surfacing in
the lower areas. If done carefully the "leveling" of the
drainfields should not affect the hydraulic characteristics of the soil
or shallow aquifer. This is mainly due to the fact that a "Pile of
wind blown sand" such as that present at this site is structure -
less and moving it around, whether by wind naturally
or by equipment has little or no effect on its physical or chemical
nature.

HYDRAULIC CHARACTERISTICS OF THE SOILS
AND SHALLOW AQUIFER AT THE
PROPOSED HATTERAS LANDING PROJECT
DARE COUNTY, NORTH CAROLINA
March 111991
Revised October 4,1995
On November 15,16,17 and 18, 1990, Mr. Kevin Martin (Certified Professional
Soil Scientist) and James Beeson evaluated the hydraulic characteristics of the
soils and shallow unconfined aquifer on the property. The property is located
adjacent to the Hatteras Ferry and NC Hwy. 12. The purpose of this evaluation
was to determine the hydraulic conductivity of the saturated zone and
transmissivity of the shallow unconfined aquifer so that this data could be used
to determine potential mounding beneath an on site subsurface wastewater
treatment system. The system is expected to receive 21,700 gallons per day of
sewage effluent. The following is a brief report of the methods utilized in this
evaluation and the results obtained. There will actually be two different systems
serving two different facilities, but due to their proximity we have treated them
as one system for the purpose of this report
Soil Descriptions
Soil auger borings were made to identify soil textures and to determine if
restrictive horizons occur on the site. Borings were performed at the locations
shown on the attached blue prints, Descriptions are attached in Appendix 1 of
this report for each boring site in the form of hand-written logs. Soils
in the areas examined have sandy textures. Such sails can be permitted for
conventional septic systems by the county with a loading rate of .8 to 1.2 gpd/ft2
on a trench bottom area basis or for a Low Pressure Pipe system with a loading
rate of .4 to .6 gpd/ftZ on an area basis. These loading rates are taken from 10
NCAC 10A.1900 (Laws and Rules for Sanitary Sewage Collection, Treatment and
Disposal). This system will employ Low Pressure distribution.
The area of the proposed system is shown on blue prints provided to you by
Quible & Associates. The potentially "restrictive" layer found on -site by Dr.
Uebler was not found in any other locabion on -site, this is discussed in more
detail later in this report Soil suitability evaluations as per current DEH

regulations were performed on -site previously by the county health department
and later by Dr. Uebler.
Transmissivi
Transmissivity of the saturated zone was determined using a multiple well
drawdown test One pumping well and six observation wells were used (see
blueprints for well locations). The methods used in these measurements were
similar to those described in Theory of Aquifer Tests, U.S. Geological Survey
Water -Supply Paper 1536-E: pp. 91-100.
Based on our previous experience on predicting mounding, we located the most
restrictive area from a soils and hydraulic standpoint and performed an 8 hour
drawdown best with a constant discharge rate of 4gpm. Measurements were
made as shown in the attached field log (see Appendix 2).
The pumping best was performed in the area where Dr. Uebler and others had
found what might be a restrictive horizon. This horizon was at 5 to 6 feet below
land surface and was made up of a darkly stained sand. It did not appear to be
a "marsh mat" like those commonly found on the Outer Banks beneath'old fill
areas or naturally deposited dunes. Such layers are sometimes present due
to the islands migration toward the mainland during which it migrates over the
sound side marshes containing organic surfaces. The "organic" layers are
usually level bedded (at the same elevation) and act as aquitards.
We actually attempted to use the very same auger hole that Dr. Uebler made at
this site for our pumping well but could not "force" the well down However,
we then moved over several feet and easily installed a pumping well and four
observation wells a little over 6' below land surface (see blueprints for locations).
The potential restrictive layer was not observed in any of these wells in this area
or in any of the other well borings on the site (for locations see blueprints). This
suggests that the layer encountered was isolated to that one hole and could have
been a partially decomposed log, stump, etc.
The actual measurements, graphs, curve matches and calculations for the pump
test are attached in Appendix 3 of this report. I should that note even though the
aquifer thickness may be as much as 60' to 80' or more we chose to evaluate the
upper 5 or 6 feet since only the shallow part of the aquifer will respond to the
additions of wastewater even though no restrictive layer is present
The effective transmissivity for the upper 5 feet of the aquifer was determined to
be about 500ft2/d (see data curves and calculations in Appendix 3 of this report).
This means that the _hydraulic conductivity is about 100ft/day. These numbers
are in the range of those'normally found in similar areas. If one used the entire
thickness of the a uifer. about 60' a T of 6000ft2 day would result The lower T

value presented is probably a more appropriate number considering the purpose
of this report because we are dealing with the reaction of the upper part of the
aquifer. This lower value was used in predicting the mounding for the
drainfields.
Boulton type curves were matched with plots of drawdown (ft) versus t/rz for
two observation wells (TW2 and TW4) which were approximately 5' and 10'
from the pumping well (see blueprints). This was necessary since the test
initially "behaved" as a confined aquifer, passed through a "delayed yield"
phase, and then began to behave as a unconfined aquifer near the end.
Therefore, this type curve matches are inappropriate.- This "switching" in the
"behavior" of the aquifer is commonly observed in barrier island pump tests.
Also attached in Appendix 4 is a Jacob "distance drawdown" graph for
data from the same two wells (TW2 and TW4) and associated calculations which
also resulted in a transmissivity of about 500ft2/d. Using both methods of
analysis of drawdown data serves as a check (i.e. if the two show drastically
different results something is wrong with the analysis or collection of data).
Seasonal High Water Table
Two methods were used to determine the seasonal high position of the water
table. The first employed the use of the "Fetter Water Table Equation" for
predicting water table heights beneath Oceanic islands (reference Applied
Hydrogeology by C.W. Fetter, Jr.,1980, -pages 144-146). The second involved the
installation and monitoring of two monitoring well networks which transected
the island (see blueprints).
The calculations in Appendix 5 for the Fetter Equation show that the predicted
average position of the water table in the center of the island would be about
1.06 feet above the level in the sound. This predicted average position is lower
than the actual water level observations made on -site, which suggests that our
measurements were made during a period of above normal water table levels.
Because the measurements are not drastically higher than predicted
average position of the water table, this supports the other evidence that there is
not a restrictive horizon beneath the proposed drainfield area.
Water level observations and fluctuation are shown in tabular form in Appendix
6 of this report and graphically on the attached blueprints. Also attached are
readings on the tide gauges which reflect tidal fluctuations and can be compared
to water levels in the monitoring wells with respect to time.
In general, the water levels in the wells did not respond to fluctuations in tidal
levels during a 36 hour observation period with the exception of well #8 which
was installed in the edge of a tidally flooded marsh. In fact, while the tide
constantly rose due to a 20 to 30 mph constant wind from the northeast, many of
the wells dropped slightly over time. This along with the data collected from the
wells on 11/30/90 by Quible & Associates (see Appendix.6 and blueprints)
tends to indicate that little tidal effect exists beneath the proposed drainfield.
It is interesting to note that when the 11/30/90 Quible data is plotted graphically
verses our data from 11/15/90 a distinct pattern appears (see blueprints). Our
data shows a constant water level slope from the primary dunes toward the
sound while the Quible data indicates the expected normal shape of the water
table beneath the island (Le. higher in the center and sloping both toward the
sound and the ocean). This suggests that our readings were made shortly after a
significant rainfall event since the levels are highest in elevation beneath the
areas with the thickest unsaturated zone (i.e. the dunes). A copy of the
Hatteras rainfall records indicates that a 24 hour rainfall event of 3" occurred a
week before our work on November 9 and 10, 1990 (see Appendix 7).
It should be noted that due to the nature of the uncoated sands in these areas the
seasonal high position of the water table cannot be determined by the evaluation
of soil color. It must be examined during expected high positions. The water
levels observed on -site should be assumed'to be seasonal high positions since
these measurements were taken in early winter when evapotranspiration is low,
one week after a 3" rainfall event and before, during and after a 20-30 mph
strong northeast wind which caused the water level in the sound to stand
constantly at a level of 1 to 1.5' above normal for 24 to 36 hours. Due to the close
proximity of the site to the sound and recent weather conditions in the area prior
to and during our measurements, we believe they are a good approximation of
the seasonal high stand of the water table. However, to again be conservative, in
our recommendations based on our mounding model, we allow for .2' rise above
and the levels observed and the mounding predicted when determining
minimum elevation required to maintain minimum separation between trench
bottoms and the water table.
Mounding
Using the measured values described above and using the inputs shown on
Table 1, various approaches were made to predict the mound which would
develop under the system(s). The systems were assumed to be rectangular for
the purposes of the model, but total square footage of drainfiield is
approximately equal to that proposed. Several different scenarios were
examined, but only the most realistic will be discussed in this report. In all cases
it was assumed that only the upper 5 to 6 feet of the aquifer responded and that
the water table remained at its seasonal high position year round.
4'
The computer model used for predicting mounding beneath a rectangular basin
with a constant recharge rate was version 3.0 of the Colorado State University
Program CSUPAW Well and Pit. This program was developed by D. Moulden,
D. Sunada and J. Warner. A journal article describing the program was
published in Groundwater Vol. 22, Number 1, Jan -Feb 1984. The
microcomputer uses Glover's Solution with consideration for Hantush's better
means of evaluating this solution by integration by parts. The Division of
Environmental Management, Groundwater Section often uses this model to
predict mounding beneath large on -site wastewater systems and for stormwater
infiltration basins.
The proposed layout of active and repair areas shown on the blue prints
submitted by Quible Associates dated 9/21/95, shows an alternation of system
and repair areas. This will tend to minimize mounding as compared to
concentrating all of the system in one area, so this approach is recommended.
However for the sake of modelling mounding beneath the systems we chose to
use a scenario where Field 2A, Repair 2A, Field 2B and Repair 2B were treated as
one active drainfield. The mounding predicted by such treatment will be
somewhat worse than that which will actually occur utilizing the alternating
system and repair design proposed. Therefore, like all other assumptions in this
report; this is a conservative approach. Repair Area 1D, Field 1D, Repair Area
1C and Field 1C is also modelled, but is treated as an independent system due to
its distance from Field 2A and 2B. We believe this approach best reflects the
proposed wastewater application methodology on -site...
Figure 1. shows the resultant mound developed beneath Field 2A, Repair 2A,
Field 2B and Repair 2B and at steady state after 3 years of daily application of
.5gpd/ft2 (13,020gpd over 26,040ft2). This'graph shows that a mound would
develop 1.0' above the existing water table.
The mounding beneath Repair 1D, Field 1D, Repair 1C and Field 1C is shown in
Figure 2. Figure 2 assumes a .5gpd/ft2loading rate (8,903gpd over 17,805ft2)
and indicates that a mound would develop to a maximum height 1.3' above the
existing water table.
Conclusions and Recommendations
Based on the findings stated above the following treatment for the drainfiields is
suggested:
A. The state requires a separation of 2' between the trench bottom and
the predicted mound height for all drainfields. Assuming a trench
depth of 171 (6" cover and 6" gravel), the proposed drainfields in
Active Areas 2A, 2B, 2C and 2D should be brought up to a uniform
elevation 'of at least 7.0'. To round these numbers off and allow for
5 .
sl
an additional "safety -factor" it would be simpler to bring the land
surface elevations up to 7.5.
Similarly Field 1A,1B,1C and 1D should be brought up to a
uniform landsurface elevation of at least 7.3.
These final elevations were determined using our predicted "high"
water table elevation of 2.8' above MSL, adding the OZ "safety
facto{' for natural water rise, adding the predicted mound height,
adding the Z separation from the trench bottom and adding 1' to
allow for installation of an LPP trench
B. The original elevations across the proposed system areas varied
and contained areas well above 8' MSL, so it was possible to "even"
the proposed drainfield areas out to the recommended elevations.
Attempting to install a system in the original topography would be
difficult and would likely result in ("seepage") effluent surfacing in
the lower areas. If done carefully the "leveling" of the
drainfields should not affect the hydraulic characteristics of the soil
or shallow aquifer. This is mainly due to the fact that a "pile of
wind blown sand" such as that present at this site is structure -
less and moving it around, whether by wind naturally
or by equipment has little or no effect on its physical or chemical
nature.
