Subject: Stormwater Permit Renewal
Stormwater Management Permit SW7081103
The North Carolina Aquarium Pier at Nags Head
Dare County
Dear Mr. White:
W a 9-0
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7081103 for a stormwater treatment system consisting of
permeable pavement, underground infiltration trenches and an infiltration basin serving
the North Carolina Aquarium Pier at Nags Head expires on December 30, 2021. This is
a reminder that permit renewal applications are due 180 days prior to expiration. We do
not have a record of receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Also, it was noted in the file review that a designer's certification that the
project was constructed in accordance with the approved plans as required by the
permit has not been submitted. Please include this with your application. Permit
application forms for renewal can be found on our website at:
https://deq.nc.gov/about/divisions/energy-rfiineral-and-land-
resources/storn-iwater/stormwater-program/post-constrLlctiori-2. North Carolina General
Statutes and the Coastal Stormwater rules require that this property be covered under a
stormwater permit.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at

As per our phone conversations, I have addressed the comments forwarded in your January 16, 2009
Request for Additional Information and am hereby forwarding you revised plans and documentation.
Specifically, comments have been addressed as follows:
Comment: There is an existing state siormwaler permit for this properly issued to Dr. E.A. Murden,
on September 27, 2000 for the construction of a 3 story-20 unit condo development that
will apparently need to be rescinded. The division will contact Dr. Murden with a request
to do so.
Response: It is my understanding that NCDENR is in the process of resolving this with Dr. Murden.
Please advise us il' we need to assist in this in any manner.
Comment: Please show the 99,329 sf of pre-existing impervious area on a set of scaled site plans. In
order to receive any type of "credit" for the pre -post discharge rate calculations when
determining which design storm volume will be required for both infiltration systems as
well consideration in not being required to pick up the drainage from the pier house and
drainage area #3 the existing impervious area needs to be documented. Please also show
the entire pier house and note it's drainage (existing & proposed) on the Site Grading &
Drainage Plans.
Response: Existing impervious coverage is now shown on Sheet C2. The Pier House is also shown
on C2. The impervious area for the Pier House (existing and proposed) is now accounted
for in the application Basin Information Table. Please note that the pier -house is
technically outside of the Project Area (technically, it is located over the Atlantic Ocean),
and therefore the impervious area associated with the Pier House is not included in the
Project Built Upon Area on the application.
3 Comment: Leniency is asked to have less than 2 feet required separation from bottom of the
infiltration basin and the seasonal high water table. Showing the existing impervious area
to note a partial redevelopment of the tract as well as the addition of any allowed "credit"
for the proposed permeable pavement within the calculations will help in the
consideration for allowances under the Alternative Design criteria.
Response: Existing Impervious coverage is now shown on sheet C2. Permeable Pavement
Supplements are included with this submittal and their appropriate BUA reduction is
accounted for on the supplements and in the Basin Information Table in the application.

Within the calculations in the Narrative Appendix. Turfstone is calculated with a C-factor
of 1.0 such that all of the rainfall onto the turfstone is accounted for. The calculations
also now tabulate the storage volume of the gravel bed under the turfstone. New totals
for storage showing excess volume available are included in the calculations as well as
the written narrative.
l Comment: If permeable pavement is to be considered for any reason to help meet the design
requirements, then the Permeable Pavement supplement form needs to be provided, one
for each drainage area. Please also revise the design storm calculations to show the
appropriate credits. Please note that for projects draining to class SA waters, the credits
given are 20% for 4" gravel base and 30% for 7" gravel base. The permeable pavement
detail on sheet CIO gives 6" gravel base whereas the note at the top of sheet C3 gives an
8" gravel base.
Response: Permeable Pavement Supplements are included with this submittal and their appropriate
BUA reduction is accounted for on the supplements and in the Basin Information Table
in the application. Sheet C10 has been corrected to reflect the 8" gravel base minimum.
Comment: The provided calculations state the 1.5" design storm volumes for both drainage areas,
but does not show how these volumes were calculated.
Response: This is addressed in the revised calculations in the narrative appendix. The runoff
volume for a 3.37 inch storm had already been calculated — the 1.5 inch storage volume
was calculated by taking the 3.37 in runoff volume, dividing by 3.37 and multiplying by
1.5.
Comment:
Please note that there are differences in the infiltration basin surface areas shown on the
plans and what has been provided for the calculations. The infiltration basin bottom
surface area at elevation 3.0fmsl within the calculations is given as 1,381 sf, whereas the
plans only show an approximate 755sf (21.1' x 35.8'). Also, the top elevation (4.5fmsl)
surface area is shown on the plans to be about 1,452sf whereas the calculations give
2,481 sf. Please verify and correct as needed to provide the required volumes.
Response:
The plan dimensioning is correct. The calculations in the Narrative Appendix and the
supplement have been corrected to reflect the basin dimensioning shown on the plans.
Comment:
Please note and provide it cross section of the Ramps and pier to help verify that this area
is considered as pervious area. I assume they will have an open wood slatted design.
Response:
Two copies of the Architectural Plans with the ramps and pier are included in this
submittal. Please note the "Pier House" discussion that has been added to the Storage
section of the Narrative which discusses the rainfall collection system noted on the plans.
Comment:
Please provide a 50 foot vegetated filter for bypass/overflows for both the infiltration
trench and basin. Please provide a cross sectional detail complete with elevations,
dimensions, level spreader and seeding. Please also provide the necessary calculations to
show that a 10yr storm event will pass through the vegetated filter with non -erosive flow
including the necessary minimum design width of the level spreader.
Response:
A traditional 50 foot vegetated filter is not feasible for this site due to geometries / site
constraints. It is important to note that this is a redevelopment project that replaces a site
with significant impervious coverage and no slonnwatcr treatment of any kind with a
proposed site that provides excessive stormwater storage and treatment. Calculations
have been added to the Narrative Appendix that demonstrate non -erosive oulfall flows
and velocities at the overflow of the proposed system.

Comment: Please verify that there are no water supply wells within 100 feet of either infiltration
system. This distance was marked as "n/a" on the supplement form but is applicable and
needs to he filled in.
Response: This entire area is served by Dare County Water for potable water supply. Furthermore,
a visual inspection of the area does not reveal the evident presence of wells. The
supplement has been revised accordingly.
Comment Please note that there are differences between the impervious area coverage noted at the
top of plan sheet CI and what is given in the application form under section 111.8,
attached table.
Response: Sheet Cl coverage notes reflected a calculation provided for the Town of Nags Head
review. The Town calculates coverage differently than NCDENR and this accounts for
the difference. In order to avoid further confusion, the coverage note has been removed.
Comment: Please do not forget to have any plans, calculations, supplements, narrative, etc. revised,
signed, sealed and dated as necessary when re -submitting.
Response: Attached, for your review, please find the following:
• 2 copies of revised Civil Plans.
• 2 copies of Architectural Plans showing pier cross -sections.
• I -copy of revised Stormwatcr Application.
• ]-copy of revised Infiltration basin Supplement.
• I -copy of Permeable Pavement Supplement DAI & DA2

how these volumes were calculated.
G�
Please note that there are differences in the infiltration basin surface areas shown on the plans and what has
been provided for in the calculations. The infiltration basin bottom surface area at elevation 3.0 fmsl within
the calculations is given as 1,381sf, whereas the plans only show an approximate 755sf-(21.1' x 35.8').
Also, the top elevation (4.5 fins]) surface area is shown on the plans to be about 1,452sf whereas the

B. CALCULATIONS
1. The basin or trench must draw down within 5 days. Spray irrigation is not acceptable as
the sole means of drawdown.
2. The design storm is 1.5" if the project is subject to Phase II or is sited within '/: mile of
and draining to SA waters. The design storm for projects subject to Phase II sited
within '/: mile of and draining to SR waters must treat the difference between the pre
and post development conditions for the 1-yr 24-hr storm. Otherwise, use V design
storm.. , ,
3. Report the bottom surface area.
4. Report the surface area at the overflow elevation.
5. Show the calculation for the minimum required volume.
6. Provide a table of elevations, areas, incremental volumes and accumulated volumes to
demonstrate that the minimum required. volume has been provided.
7. Calculations are signed, sealed & dated.
1.
8. Report the Drainage Area an&Built-upon area for each basin or trench.
9. The seasonal high water table must be at least 24" below the proposed bottom
elevation of the system. For Phase II projects, at least 12"'of this must be in naturally
occurring soils.
10. Al runoff in excess of the design storm must bypass to a vegetated filter prior to
entering the basin or trench. If the system is designed to store a larger design storm
(generally 2-3 times the minimum), the requirement for an offline bypass can be waived.
Please contact the Division to determine what design storm is appropriate for the
project.

Scott;
The purpose of this memorandum is to formally request a two -week extension of the deadline to respond to the
request for additional information for the NC Aquarium Pier at Nags Head. As we discussed last week, there
was a delay in our receipt of the letter due to weather and the comments are also fairly extensive. I am
actively working on the response a anticipate having a package to you later this week.

Otherwise, it will delay construction. The original permit remains
