Paul
We received your letter requesting additional information, dated August 23 2007 for the above
referenced project and offer the following response to your comments and questions We have
addressed your comments in the some order as your letter
�1 The observation well was Inadvertently left off the plan, I have added the observation well
detail to the attached plan We have also added and observation well to the carrier pipe on
ltra _ nftlon trench #3
/2 The dimensions that were shown on the plan are the correct widths of the trenches I have
V revised the dimensions on the plans to clearly show that the dimension is to the stone, I have
also revised the supplement forms with the correct trench widths, which is 33' for both "A" and
"B" trenches and 18' for trench "C"
3 / The dimensions that are shown on the plan are the lengths of perforated pipe which is the
/ trench length, the stone of the trench will stop at the Inside edge of the header pipe, this is
VVV Indicated on the header detail The header pipe Is not perforated so does not require the
stone or fabric wrap To help make this as clear as possible I have revised the way the trench
stone is Indicated on both the plan and the header detail The Information on the supplement
forms is correct
4 Based on the information that was provided on the plan there would be no way to come up
/ with any other number of pipe runs and lengths than what was the intended designed, but to
v make sure this is perfectly clear, I have revised the plans to Indicate the length and number of
perforated pipe runs and that total length and the amount of non -perforated header pipe for
/ each of the Infiltration trenches
The surface area of trenches and the volumes provided on the supplement forms, calculations
and plans are correct and consistently show between the plan the calculations and the
supplement forms only the trench widths were miss labeled on the supplement forms, and you
now have corrected copies of the supplement forms
The additional $500 00 fee check is enclosed If you should require any further information do not
hesitate to call our office

Dear Mr Skehan
Michael F Easley, Governor
William G Ross Jr, Secretary
North Carolina Department of Environment and Natural Resources
Coleen H Sullins, Director
Division of Water Quality
The Wilmington Regional Office received a Stormwater Management Permit Application for 4586
Long Beach Road on August 2, 2007 A preliminary review of that information has determined that
the application is not complete The following information is needed to continue the stormwater
review
As previously requested, please provide a detail for the 2 observation wells being
provided for each trench system
2 Please clarify trench widths The supplements Ilst3 nd for Trenches A, B,
and C, respectively Sheet #C2 dimensions the widths as 3ndor A, B, and
C, respectively
3 Please clarify the trench lengths The supplements list 57', 57', and 112' for Trenches
z/ A, B, and C, respectively It appears that Sheet #C2 dimensions 57', 57', and 112' for
the length of each pipe run for A, S, and C, respectively Each trench should be longer
than a pipe run
Please add the number of pipe runs and the length of each pipe run to the linear
v feet/matenal label for each trench system on Sheet #C2
t 5 Based on the above Items, please clarify the provided volumes and revise supplements,
calculations, and plans for consistency
�j Additional fees, not to exceed 50% of the original permit application fee, may be charged for
subsequent reviews due to the Insufficiency of a permit application, as specified by Section
11 4A of S L 2003-284
Because the application has significant permitting issues/deficiencies, a resubmittal fee
of $500 will be required in order for this project to remain in the express program
Please note that this request for additional information is in response to a partial, preliminary review
The requested Information should be received by this Office prior to September 6, 2007, or the
application will be returned as incomplete The return of a project will necessitate resubmittal of all
required Items, including the application fee

4586 LONG BEACH ROAD
Oak Island, NC
Brunswick County
July, 2007
DESIGN NARRATIVE
Existina Site
Darske, LLC is proposing the development of a 1 03 acre tract of land, in Brunswick County
The proposed protect site is located at 4586 Long Beach Road (NC 133), just to the north of
North Hampton Drive The site is currently undeveloped
Figure 1 - USGS
The Brunswick County SCS Sod Survey indicates that the property's sod is Yaupon silty clay
loam (YaB) Yaupon silty Gay loam is a poorly drained to moderately well drained clayey sod
Surface runoff is slow and permeability is slow Engineering Consulting Services, LTD
preformed a field geotechrncal investigation of the sites There report indicates that the sods on

the site have an infiltration rate of 3 0 to 4 2 inches per hour at the tested depth of 10-12"
inches below grade and a seasonal high water table at a depth of 26 to 30 inches below grade
A copy of their report is included in this report No wetlands have been identified on the
property The property is located in a basin that drams to the Calf Gully Creek, within the
Lumber River Basin and is not classified
Proposed Improvements
The proposed development will consist of 4 retail/office units, paved access drives and parking,
the necessary utilities services will be provided from the existing infrastructure and a
stormwater management system will provide treatment and pre/post attenuation The site will
be accessed from the adjoining parcels located to the east and west of the subject property A
total of 43 parking spaces are provided to serve the development The proposed impervious
areas will are made up of 10,000 sq ft of buildings, 23,805 sq ft of asphalt and 1,754 sq ft of
concrete paved areas, making the total built upon area 35,559 sq ft , 79% of the 1 03 acre total
property area
NCDENR requires that a BMP be provided to remove stormwater pollutants (treatment) from
the first 1" runoff In order to meet the treatment and attenuation requirement, the project's
stormwater runoff will be captured in infiltration trenches The trench bottom will be a minimum
of 2' above the seasonal high water table A bypass overflow structure is provided to discharge
excess stormwater The infiltration trenches will draw down in 2 to 5 days

Dear Mr Roney,
ECS Carolinas, LLP (ECS) recently conducted an infiltration evaluation for the proposed
infiltration area for the site located at 4578 Long Beach Road in Wilmington, North Carolina
I his letter, with attachments, is the report of our evaluation
Field Testing
On April 13, 2007 ECS conducted an exploration of the subsurface soil and ground water
conditions at three requested locations shown on the attached Site Diagram The purpose of this
exploration was to obtain subsurface information of the suitability of the in -place soils for the
proposed infiltration area We explored the subsurface soil and ground water conditions by
advancing one hand auger boring into the existing ground surface at the three requested boring
locations We visually classified the subsurface soils and obtained representative samples of
each soil type encountered We also recorded the ground water level observed at the time of
each hand auger boring The attached Infiltration Evaluation Forni provides a summary of the
subsurface conditions encountered at each hand auger boring location
The ground water level and the seasonal high ground water level (SHWL) were estimated at
each bonng location below the existing grade elevation Below is a summary of each boring
location

this is one of the projects that Janet was going to give you
Vincent had previously visited the site and told him that it was not

We are getting projects with high shwt and don't seem to have options
float sand filters in the water and after Kelly's memo, it appears we
that since they will eventually leak

Brad,
Please contact Vincent Lewis to schedule a site visit to verify the soil and SHWT at this site when the
infiltration basin or trench location is accessible, without fill Infiltration stormwater systems must be
located innative soil with good/clean infiltration rates and a minimum of 2 foot separation above the
SHWT
On behalf of DWQ, Vincent Lewis visited the site this morning, as scheduled by the soil scientist, but no
one was there at the 8 00 a m scheduled time The site was found with fill and unsuitable for infiltration
with too much clay and clumps Vincent was not able to determine the SHWT depth due the the clay

Date/Time of Soils Investigation 6 -/o Q / 9 • JOy l'NCewr Lew IS
Summary/Comments
All proposed infiltration areas and existing, active utility lines located within the proposed basin/trench
must be marked and flagged If these areas are not flagged, the Soils Scientist reserves the right to
decline to do the investigation If the proposed infiltration system will be located in an area of existing
pavement and there is no open area nearby, equipment capable of breaking through the impervious
layer must be provided The soils investigation does not take the place of a soils report prepared by
an appropriate professional The Soils Scientist will only verify the soil conditions that are reported in
the Soils Report, and make a determination as to the suitability of the site to meet the infiltration
design requirements under NCAC 2H 1000, and assumes no liability should the system fail

Oak Island, NC
Brunswick County
May 7, 2007
DESIGN NARRATIVE ,
Existing Site
Darske, LLC is proposing the development of a 1 03 acre tract of land, in Brunswick County
The proposed protect site is located at 4586 Long Beach Road (NC 133), just to the north of
North Hampton Drive The site is currently undeveloped
Figure 1 - USGS
The Brunswick County SCS Soil Survey indicates that the property's soil is Yaupon silty clay
loam (YaB) Yaupon silty clay loam is a poorly drained to moderately well drained clayey soil
Surface runoff is slow and permeability is slow Engineering Consulting Services, LTD

preformed a field geotechnical investigation of the sites There report indicates that the soils on
the site have an infiltration rate of 3 0 to 4 2 inches per hour at the tested depth of 10-12"
inches below grade and a seasonal high water table at a depth of 26 to 30 inches below
grade A copy of their report is included in this report No wetlands have been identified on the
property The property is located in a basin that drains to the Calf Gully Creek, within the
Lumber River Basin and is not classified
Proposed Improvements
The proposed development will consist of 4 retail/office units, paved access drives and
parking, the necessary utilities services will be provided from the existing infrastructure and a
stormwater management system will provide treatment and pre/post attenuation The site will
be accessed from the adjoining parcels located to the east and west of the subject property A
total of 43 parking spaces are provided to serve the development The proposed impervious
areas will are made up of 10,000 sq ft of buildings, 23,805 sq ft of asphalt and 1,754 sq ft of
concrete paved areas, making the total built upon area 35,559 sq ft , 79% of the 1 03 acre
total property area
NCDENR requires that a BMP be provided to remove stormwater pollutants (treatment) from
the first 1" runoff In order to meet the treatment and attenuation requirement, the project's
stormwater runoff will be captured in infiltration trenches The trench bottom will be a minimum
of 2' above the seasonal high water table A bypass overflow structure is provided to discharge
excess stormwater The infiltration trenches will draw down in 2 to 5 days

All proposed infiltration areas and existing, active utility lines located within the proposed basin/trench
must be marked and flagged If these areas are not flagged, the Soils Scientist reserves the right to
decline to do the investigation If the proposed infiltration system will be located in an area of existing
pavement and there is no open area nearby, equipment capable of breaking through the impervious
layer must be provided The soils investigation does not take the place of a soils report prepared by
an appropriate professional The Soils Scientist will only verify the soil conditions that are reported in
the Soils Report, and make a determination as to the suitability of the site to meet the infiltration
design requirements under NCAC 2H 1000, and assumes no liability should the system fail

ECS Project No 22 12996
Dear Mr Roney,
ECS Carolinas, LLP (ECS) recently conducted an infiltration evaluation for the proposed
infiltration area for the site located at 4578 Long Beach Road in Wilmington, North Carolina
I'lus letter, with attachments, is the report of our evaluation
Field Testing
On April 13, 2007 ECS conducted an exploration of the subsurface soil and ground water
conditions at three requested locations shown on the attached Site Diagram The purpose of this
exploration was to obtain subsurface information of the suitability of the in -place soils for the
proposed infiltration area We explored the subsurface soil and ground water conditions by
advancing one hand auger boring into the existing ground surface at the three requested boring
locations We visually classified the subsurface soils and obtained representative samples of
each soil type encountered We also recorded the ground water level observed at the time of
each hand auger boring The attached Infiltration Evaluation Form provides a summary of the
subsurface conditions encountered at each hand auger boring location
The ground water level and the seasonal lugh ground water level (SIiWL) were estimated at
each boring location below the existing grade elevation Below is a summary of each boring
location
