Stormwater Project No. SW8 010108
Jacksonville Country Clubhouse
Onslow County
Dear Mr. Faye:
The Wilmington Regional Office received a Stormwater Management Permit Application for Clubhouse
Facility on January 5, 2001. A preliminary review of that information has determined that the application is not
complete. The following information is needed to continue the stormwater review:
Please delineate all wetlands on site; disturbed or undisturbed, or note on the plans that none exist.
2. Please submit an original signature on page 4 of the' application. Photocopies are not acceptable.
5. The sediment chamber should sheet flow into the sand filter over the weir, not through the 2" pipes
at the bottom of the chamber. Please delete the 2" pipes.
4. The entire sand filter and sediment chamber must be lined with an impervious liner. If the soils are
not suitable for infiltration, then the BMP sand filter design criteria must be adhered to. Based on
information from the Central Office, the intent of the sand filter design is to provide an impervious
barrier between the unsuitable soils and SHWT, to maintain a permanent pool of water in the
sediment chamber, to prevent the resuspension of sediment, and to ensure that all runoff is directed
into the sand chamber. If the entire filter and sediment chamber are not lined; the system must be
redesigned under the infiltration basin design criteria.
5.- In keeping with the BMP design, and to encourage sheet flow across the filter, please provide
additional weir cuts. A single weir will concentrate the runoff at a single point in the filter, whereas
a number of smaller width weirs will encourage the runoff to sheet flow over a larger area of the
filter.
Please provide dimensions for the existing and proposed buildings, parking, streets, drives, walks,
etc., that will drain into the filter.
Please list both the owner's name and title (.terry Bittner / Title?) and the si(Tiling official's name and
title (Michael Faye 1 General Manager) on page l of the application. What is Mr. Bittner's title? The
signature authorization only says "Board of Directors".
Please complete the requested information in Section III, Part G, the Basin Information chart on page
2 of the application. It is incorrectly marked as "NIA".

9. The Impervious Surface Area chart in Section 111, Part 6, indicates that the total impervious area
draining to this filter is 2.39 acres. Is this correct? From the drainage area provided on sheet C-6A,
the drainage area is 2.39 acres, and not all of the 2.39 acres appears to be impervious. Please list only
the impervious (i.e., built -upon) area in that section.
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 March 15, 2001, or the application will be returned as
incomplete_ The return ofa project will necessitate resubmittal of all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time extension
to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by
which you expect to submit the required information. The Division is allowed 90 days from the receipt of a
completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an approved
Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action
pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original documents that need
to be revised have been sent to the engineer or agent. All original documents must be returned or new originals must
be provided. Copies are not acceptable. If you have any questions concerning this matter please feel free to call me

Dear Ms. Lewis:
F
C IVED

We have reviewed DWQ staffs comments for the above referenced project and our response is as
follows:
There are no wetlands deleniated on our plans. Within the 8.83 acres designated for the project
impact area, and more importantly the areas immediately adjacent to the 1.70 acre project built -
upon area, there are no known wetland areas. The zero -flow creek adjacent to the sand filter is a
dry creek bed, except during rainfall events.
2. Our submittal should have had Mr. Faye's original signature. We will forward the copy returned
to our office to Mr. Faye and ask him to re-sign and re -submit the form to your office. See also
Response No. 7.
Did staff review our Design Methodology for the proposed filter? if they had, one would have
understood that the 16.0' weir is the flow spreader and the concrete/rip rap splash pad on the filter
side of the weir wall acts to further disipate the flow velocity and spread the flow across the end of
the sand filter cell.
The 2-inch pipes are only underdrains for the fore bay section to prevent stagnated water and
vector problem potentials. The desire of the Club is to make this stormwater facility one of the
fairway hazards, but not to create a manmade wetland. The fore bay will function as required,
with or without standing water.
We do not want to delete all of the 2-inch pipes, but will do so if required by DENR staff. We
would want the deletion requested and signed by Rick Shiver.
4. We disagree with DENR's request for a liner. It is not required in the Manual of Practice, and
certainly has no justifiable benefit for this project application. We specifically provided our
written justification for excluding the liner. Staffs request of a liner begs the question of whether

or not the specific application of this design is completely understood. We have provided
considerable back-up data on this issue, and we recommend that DENR not require the use of a
liner, in this specific case.
The whole weir wall is the weir 16' — 0". Again, we feel that staff has not understood the design
intent before issuing these comments.
We provided a full set of Plans. We have shown the drainage area assessment calculations (sce
Sheet C-6A & C-613). The information you request has been provided.
7. Mr. Bittner is a member of the Board of Directors for the Jacksonville County Club Corporation
and is in charge of Audit & Administration of the Corporation. He is a Corporate officer. We
have added his name as requested to page 1 of the Application. If the DENR staff is still not
satisfied, please contact the Country Club directly to resolve this issue.
We have addressed Sect. III, Part 6. Please understand that the 8.83 acres is the designated project
area within the 180 acre golf course. Initially this was chosen arbitrarily to comply with LOW
DENSITY impervious limits, which no longer apply to this project.
9. For design criteria and filter sizing purposes, we included everything within the 2.39 acres as
impervious. Once traffic crossover during demolition and construction has finished, grassed areas
will be well compacted. Please understand that we have purposely provided more filter capacity
than the as -built conditions will need. Therefore, use 2.39 acres, the filter design will handle this
size area.
The staff review comments of 2/15/01, in our opinion, do not warrant an additional 90 days review by
staff. Regarding Comment #4, we will require a design consultative session with DENR staff prior to
amending our design to include a liner. We strongly disagree with the cost -benefit and regulatory need
for a liner in this specific BMP application. Groundwater contamination by the filter is not an issue for
this project.

Stormwater Management
Sand Filter
Design Criteria
BACKGROUND
The Jacksonville Country Club desires to build a new Country Club Facility on the site of the existing
Country Club. Due to the increase in impervious surface parking, the new facility will exceed 1.0 acres of
disturbance. Furthermore, although the project area represents less than 30 percent of the built -upon area,
the clustered development nature of the proposed construction and the need to install a storm sewer
system classifies this project as HIGH DENSITY development.
The site location, Country Club design and soil morphology within the golf course are such that neither
(1) Wet Detention Ponds nor (2) Infiltration Basins are possible. Therefore, the Design Intent is as
follows:
1. Where possible, parking lot runoff is directed to the golf course fairways.
2. Runoff from undisturbed areas, pervious and impervious will be allowed to drain,
untreated to the Creek by means of existing surface drainage channels.
3. A significant area of undisturbed asphalt will be incorporated into the new stormwater
management system.
4. Stormwater runoff from impervious surfaces will be collected in a series of drop inlet catch
basins and conveyed to a key manhole structure near the access road culvert at the creek.
5. The KEY manhole will be designed with an overflow weir, set at a design height which
will allow runoff in excess of the first flush (1-inch) to bypass the stormwater filtration
system and discharge directly to the creek.
6. The stormwater filter shall have (1) a sediment chamber, (2) CMU overflow weir and
(3) a surface sand filter with underdrain discharge to the Creek. The filter design shall be
in accordance with NCDENR's Stormwater Best Management Practices Manual, latest
edition.
7. The Sand Filter System design criteria, attached hereto, identifies State minimum standards
and the actual design intent, which equals or exceeds State criteria.
8. Since no BMP form is available for Sand Filter Systems, the Infiltration Basin Supplement
Form has been modified for this project submittal.

The NCDENR Manual for Stormwater Best Management Practices (SwBMP), dated April 1999,
establishes the average recommended filtration rate at 0.04 gal.min/sf with one (1) foot of
.head on the sand surface. A second requirement is that the first inch of rainfall runoff should
pass through the filter within a 24-hour period.
Sand from local sources within the Onslow County area are able to meet the following
specifications:
OO Effective grain size: 1.0 -- 2.0 min
© Uniformity Co -efficient: < 3
0 Dust Content: < 1.0
® Permeability: 6 — 20 in/hr. 4 Design = 4.0 in/hr.
The Design Specification for sand filter media can be met by local sources of supply. However, prior to
delivery, the sand shall be tested for compliance with the above standards.
The following analysis has been prepared for this specific Stormwater Filter application.
❑ Design Permeability of Filter Sand: 4.0 in/hr.

❑ Sand Filter Maintenance
The proposed Stormwater Sand Filter for the Jacksonville Country Club will be located below the
No. 10 Tee box, in the fairway rough area. Consequently, it is being designed to also serve as a
hazard area for golf play. It is, therefore, reasonable to expect that the grounds keeping crew will
maintain the sand filter in much the same way and frequency as the many sand traps around the
course.
Regular maintenance should occur on a daily/weekly basis. Raking, debris removal and sand
replenishment, as needed, will occur daily, whether or not there was a storm/rainfall event.
When it is observed that standing water remains in the filter for more than 24 hours, maintenance
attention would involve the removal of the first 2-3 inches of discolored sand, and replacement
with new sand.
The forebay sediment chamber should also be regularly maintained. The forebay is designed to
drain to the filter gallery through 2-inch drain pipes located along the base of the center weir wall.
Pea -gravel covers the inlet side of the wall drains. From time to time the pea -gravel will have to
be removed and replaced. AIso, the buildup of silt should be removed unless it is the desire to
create a man-made wetland in the forebay gallery.
Due to the suspended solids content of the stormwater, it is only fair to assume that a "silt mat" will build
up in the top 1-2 inches of sand. This mat will reduce the natural permeability of the sand. Consequently,
local sands with permeabilities of 10-20 in/hr. will be considered in order to assure an average filtration
rate of 0.04 gpm/s.£

INTERIOR FILTER -BOTTOM LINER ASSESSMENT
for
STORMWA TER SAND FILTER
Jacksonville Country Club
Onslow County
Jacksonville, North Carolina
December 27, 2000
❑ NCDENR DESIGN REVIEW QUESTION:
Should a rubber liner be placed in the "forebay" and filter gallery of the proposed stormwater
sand filter?
❑ DESIGN ENGINEER'S RESPONSE:
No. The purpose of the BMP sand filter is to pre -filter the first flush of stormwater runoff and
discharge to the unnamed, zero flow, creek.
The creek bottom is sufficiently lower than the filter underdrain to assure that the seasonal high
groundwater table will not infiltrate the filter bed and adversely impact filter operations.
The design intent is to completely drain the forebay and filter within 24 hours of a storm event.
Since the filter is to be incorporated into the hazard configuration of the No. 10 fairway, daily
maintenance and grooming is to be expected.
❑ KEY POINTS:
1. A lined forebay gallery provides no benefit to BMP operations. Sedimentation occurs
equally whether the forebay is dry or wet.
2. Due to the intermittency of significant storm events, forebay flushing will not occur at a
frequency sufficient to prevent stagnation and insect control problems. The forebay is
designed to slowly drain through the sand filter, within a 24-hour period.

3. The filter gallery does not require a bottom liner because the design intent is to
discharge to the creek. Any losses of water through bottom infiltration is a positive
benefit.
Groundwater infiltration of the filter bottom and storage gallery is not a problem for this
specific application because of slope and proximity location of the zero flow creek.
4. The NCDENR, "Stormwater Best Management Practices" Manual, April 1999,
DOES NOT stipulate the need for filter bottom liners.

3.0 Sand Filters
3.1 Introduction
Sand filters are intended to address the spatial constraints that can be found in intensely developed urban
areas where the drainage areas are highly impervious. They can be used on small, urban sites that would
not normally support the hydrology of a wet detention pond and where the soils would not support an
infiltration device.
The design procedure described below is based on the experience and equations that were developed by
the City of Austin, Texas, the State of Maryland, and the State of Delaware. Much appreciation is
extended to Earl Shaver of the Delaware Department of Natural Resources for the use of his design
guidance.
While sand filters are new in the area of stormwater treatment, they have been used for many years to
treat wastewater and as part of the process of purifying drinking water. In most cases, monitoring results
suggest that sand filters used to treat stormwater behave similarly to sand filters used in wastewater
treatment. They have been demonstrated to be effective in removing many of the common pollutants
found in urban stormwater runoff, especially those found in particulate form. They have also been
shown to have at least a moderate level of bacterial removal. They have not been effective at removing
total dissolved solids and nitrate -nitrogen and, for this reason, would best be used upstream of a
vegetated filter.
There are two basic components of a sand filter design: the sediment chamber and the sand chamber.
They are both important parts of the design, and neither can be omitted. The purpose of the sediment
chamber is to reduce the amount of sediment that reaches the sand chamber and to help ensure that
stormwater reaches the sand chamber as sheet flow. The purpose of the sand chamber is to trap the finer
sediment and sediment bound pollutants, and to provide a media for microbial removal of bacteria.
Sand filters work by receiving the first flush of runoff and settling out the heavier sediment in the
sediment chamber. Water then flows to, and is spread over the sand bed where pollutants are either
trapped or strained out. Sand filters are to be used only for drainage areas that have been stabilized.
Sediment suspended in runoff during construction could quickly clog the sand filter and render it useless.
By excluding disturbed areas from draining to the sand filter, the actual pollutant loadings that must be
treated by the sand filter are those generated by the land use activity for which it is designed. Drainage
areas directed to each sand filter should be kept below 5 acres in size. Larger drainage areas are less
likely to be entirely impervious, and it is more difficult to distribute the flow of runoff across the sand
bed. Sand filters systems can be used on large parking areas and other sites larger than 5 acres if the site
is divided into smaller drainage areas that feed individual sand filters.
Sand filters are intended primarily for water quality enhancement and must be designed to handle the
runoff from frequent storm events. They must be designed to accommodate all the runoff which drains to
them, so the drainage area must be determined for actual design. For -the State of North Carolina, water
quality controls must be designed for 85% removal of Total Suspended Solids. Design for this level of
treatment requires the bulk of TSS removal occur on the frequent, smaller volume storms. Sand filter
systems designed according to the requirements outlined here for control of the runoff from the first inch
23

f
of rainfall are considered to meet the 85% TSS removal requirement. In most of North Carolina, this
represents the runoff of over 90% of all storm events.
3.2 Design Requirements
Sediment Chamber:
• Volume = 540 ft3 per acre of drainage area
• At least 18 inches deep
• A surface area of at least 360 ft2/acre
• Positive drainage to this chamber either in conduit or surface drainage
• No outlet except to sand chamber
• Outlet to the sand chamber to result in sheet flow
Sand Filter Chamber:
• Volume = 540 ft3 per acre of drainage area
• At least 18 inches of sand particles less than 2 mm average diameter
• A surface area of at least 360 ft2/acre
An outlet positioned and sized such that the sand chamber will drain completely in 24 hours
No single outlet pipe sized greater than 6 inches, in order to provide a minimum of 12 inches of sand
above pipe
General:
Access to both chambers must be sufficient for all maintenance activities. Because the sediment
from at least the first chamber will be somewhat wet when maintenance occurs, heavy equipment
access should be provided.
The filter must be designed to structurally withstand any load that is expected to occur (water
quantity, sediment quantity and surface loading).
The design parameters above assume an average filtration rate of 0.04 gal/min/ft2 with one foot of head
on the sand surface. This rate is needed in order to allow the runoff from the first inch of rainfall to
pass through the filter within a period of 24 hours. The effect of this is that each square foot of sand
must transmit approximately 62 gallons of water over a period of 24 hours. This design assumes that
drainage through the sand chamber will be occurring throughout the duration of runoff. Storms that
exceed one inch of runoff, depending on their intensity and duration, may overflow the sand filter. In
these situations, runoff may not receive the same level of treatment as runoff from smaller storms.
Where stormwater quantity control is required, runoff that will flow over the sand filter must be
considered in addition to the water flowing from the normal outlet from the sand filter.
Two examples of sand filters are shown below. The first example, Figures 4 and 5, is one that might be
used in an area where land values are very high, or where there are severe physical limitations in siting a
BMP. This design uses a concrete structure and can be located or constructed in such a way as to occupy
no developable land. The second example, Figure 6, is a sand filter that might be used on a project where
spatial limitations are present, but there is some land available for stormwater management. This design
does not use the same precast -concrete structure that is used above, and would be less expensive to
construct, but would take more land area than the first example presented.
24

3.3 Maintenance
Regular maintenance is essential to the long-term performance and durability of the sandfilter, as it is
with all stormwater BMPs. At least once a year each filter must be inspected after a storm to determine if
the filter bed is passing the runoff as expected. Depending mostly on the activities occurring in the
drainage area, most filters will show some decreased capacity for filtration after a few years.
Maintenance operations must be performed when storms of approximately one inch are not passing
through the filter within 24 hours. Maintenance for sand filters consists of removing the first two or
three inches of discolored sand, and replacing this with new sand. The sand that has been removed
would then be dewatered, if necessary, and then landfilled. At the same time that maintenance is
performed on the sand chamber, the sediment chamber should also be pumped and cleaned. It is most
likely that the sediment removed from the first chamber will need to be dewatered before it will be
accepted at a landfill.

Design Criteria
BACKGROUND
RECEIVED
JAN 0 5 2001
DWQ
PROJ #
The Jacksonville Country Club desires to build a new Country Club Facility on the site of the existing
Country Club. Due to the increase in impervious surface parking, the new facility will exceed 1.0 acres of
disturbance. Furthermore, although the project area represents less than 30 percent of the built -upon area,
the clustered development nature of the proposed construction and the need to install a storm sewer
system classifies this project as HIGH DENSITY development.
The site location, Country Club design and soil morphology within the golf course are such that neither
(1) Wet Detention Ponds nor (2) Infiltration Basins are possible. Therefore, the Design Intent is as
follows:
Where possible, parking lot runoff is directed to the golf course fairways.
2. Runoff from undisturbed areas, pervious and impervious will be allowed to drain,
untreated to the Creek by means of existing surface drainage channels.
A significant area of undisturbed asphalt will be incorporated into the new stormwater
management system.
4. Stormwater runoff from impervious surfaces will be collected in a series of drop inlet catch
basins and conveyed to a key manhole structure near the access road culvert at the creels.
5. The KEY manhole will be designed with an overflow weir, set at a design height which
will allow runoff in excess of the first flush (1-inch) to bypass the stormwater filtration
system and discharge directly to the creek.
6. The stormwater filter shall have (1) a sediment chamber, (2) CMU overflow weir and
(3) a surface sand filter with underdrain discharge to the Creek. The filter design shall be
in accordance with NCDENR's Stormwater Best Management Practices Manual, latest
edition.
The Sand Filter System design criteria, attached hereto, identifies State minimum standards
and the actual design intent, which equals or exceeds State criteria.
8. Since no BMP form is available for Sand Filter Systems, the Infiltration Basin Supplement
Form has been modified for this project submittal.

Design of Filter Flow -Through Capacj&
The NCDENR Manual for Stormwater Best Management Practices (SwBMP), dated April 1999,
establishes the average recommended filtration rate at 0.04 gal.min/sf with one (1) foot of
head on the sand surface. A second requirement is that the first inch of rainfall runoff should
pass through the filter within a 24-hour period.
Sand from local sources within the Onslow County area are able to meet the following
specifications:

The Design Specification for sand filter media can be met by local sources of supply. However, prior to
delivery, the sand shall be tested for compliance with the above standards.
The following analysis has been prepared for this specific Stormwater Filter application.
❑ Design Permeability of Filter Sand: 4.0 in/hr.

We are writing to inquire as to current review status of the above referenced project. It has been over
30 days since our last comment response and we have received no indication of further action. Since
several of our responses may require a scheduled meeting, we feel that this delay has negatively
impacted the timeliness of the Engineer's delivery of product to the Client.
Rick, please look into this, we never intend to "ruffle feathers", but sometimes it occurs in defense of
design intent and methodology. We want to resolve outstanding issues in a professional manner. We
have asked for nothing more than a second opinion, by a P.E., of the interpretation of intent within the
BMP Design Manual regarding Sand Filter Design. We do not understand the reason for extending the
staff review of this project to the extent experienced to date.

Dear Mr.' Shiver:
We are 'ting to inquire as to current review status of the above referenced project. It has been over
30 days s nce our last comment response and we have received no indication of further action. Since
several o our responses may require a scheduled meeting, we feel that this delay has negativeIy
impacted the timeliness of the Engineer's delivery of product to the Clicnt.
Rick, plc sc look into this, we never intend to "ruffle feathers", but sometimes it occurs in defense of
design ini ent and methodology. We want to resolve outstanding issues in a professional manner. We
have askt d for nothing more than a second opinion, by a P.E., of the interpretation of intent within the
BMP Dc 'gn Manual regarding Sand Filter Design. We do not understand the reason for extending the
staffrevi w of this project to the extent experienced to date. j

Dear Mr. Morgan:
The Division received your letter of March 29, 2001, regarding the interpretation of the design requirements
for a sand filter. I checked with the Central Office staff and although the impervious liner requirement was not
specifically mentioned in the BMP document, it was the intent of the original writer- the State of Delaware, and
the Division, to require a liner. As specified in the introduction of Chapter 3, sand filters can be used on "small,
urban sites that would not normally support the hydrology of a wet detention pond and where the soils would not
support an infiltration device." Without the liner, this structure becomes an infiltration basin, and must be designed
per those requirements. In accordance with the opinion of Central Office staff, an impervious liner is required for
all sand filter systems, including the sediment chamber. Please contact.leanette Powell at 919-733-5083 if you have
further questions concerning this requirement.
That being said, on April 16, 2001, the Division met the Regional Soil Scientist at the Jacksonville Country
Club site and had him do some shallow soil borings in the proposed location of the sand filter. One boring was done
to a depth of 4', and the other to a depth of 2'. The 2' boring; adjacent the small creek, showed some clay, and
evidence of water, while the 4' boring, approximately 20' upsiope from the 2' boring, showed a layer of hard clay
at least 4' thick and also some water. This hard clay will suffice as the impervious liner required for sand filters by
the BMII document. Since the T boring did not have as much clay, the permit will require that a minimum 8" layer
of that. onsite native clay be placed on the bottom of the entire flier, with the geotextile fabric and 18" sand layer
on top of that. This may mean that some clay will need to be added to the filter closest to the creek.
The Division received the requested additional information on February 27, 2001. The following information
is needed to continue the review:
As previously requested, if there are no wetlands on the site, please place a note on the plans to that effect.
2. I will accept your design of a single 16' weir at this time. If erosion becomes a problem, the permit will
require that multiple weir cuts be added to provide better flow distribution and lessen the erosive potential.
As previously requested, please provide dimensions for the existing, and proposed buildings, parking, streets,
drives, sidewalks, etc.
Please revise the sand filter and sediment chamber detail to show the required 8" clay layer as the required
impervious liner.

5. Hie weir design you propose with the 2" weepholes at the bottom of the sediment chamber is not in
accordance with the sand filter design shown in Chapter 3 of the l3MP document. It is the intent of sand filter
design that some runoff will remain standing in the sediment chamber until pushed over the weir by the next
storm. As proposed, the runoff will fill the sediment chamber and will go through those 2" weepholes, not
over the weir. In accordance with the intent of sand filter design, you can either delete the weepholes entirely
and let the weir act as the sole spreader mechanism, or relocate them so that their invert creates a rninimurn
sediment chamber depth of 18", and is at or above the sand elevation. You can also elect to convert the
design to a wet detention pond, which would make an excellent water trap for the golf course. Please revise
the details, as needed.
]'lease 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 May 16, 2001, or the application will be returned as
incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time extension
to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by
which you expect to submit the required information. You will not receive an acknowledgment of the time
extension, however, the project must be submitted by the date indicated in your request letter. The Division is
allowed 90 days from the receipt of a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an approved
Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action
pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original documents that
need to be revised have been returned to the engineer or agent. All original documents must be returned to the
Division or new originals must be provided. Copies are not acceptable. If you have any questions concerning this
matter please feel free to call me at [phone].

A note will be placed on the plans that no wetlands are involved on the work site.
2: We understand that our proposed weir cut of 16' is acceptable at this Time. W.-understand that if I
erosion is problem weir cuts will be added later. f
3. We will add any dimensions necessary; however; we would appreciate any clarification that will
assist us in expediting this comment's resolution. if there are specificicalculations in question for
impervious areas noted on the Sheet C-6A we would gladly recheck. Do you have the existing site
plan as well as the new building plan in your files, if not We will gladly provide this and any other
dimensions -you need.
4. We will itcluire the Contractor to supplement the clay liner as require in areas found to be
insufficient for the liner requirement. We understand that the clay found in your 4' borings will
suffice for a clay liner.
. 5; 2." weep holes will be eliminated. y
Thank you for all°your hard work in reviewing this stormwater design and we appreciate your efforts in the
Fernnit Procedures.
