Subject: Approved Plan Revision (Revised)
Westfall Office Park
Stormwater Project No. SW8 990306
New Hanover County
Dear Mr. Trask:
On March 31, 2005, the Wilmington Regional Office received a plan revision for Stormwater
Management Permit Number SW8 990306, Westfall Office Park, and issued an approval on April 7,
2005. The approval letter referenced the incorrect permit number. This approval letter replaces the one
dated April 7, 2005. The approved revisions include changes to the drainage area layouts for Ponds 1
& 2 due to the taking of right-of-way for the widening of Military Cutoff Road. The taking created a
condition wherein the permitted ponds were available for treatment of runoff, but parts of the drainage
areas that had been approved to be treated in the ponds could not be developed. The Division is
allowing the taken right-of-way to be swapped for the former New Hanover County Library Site, as long
as the new total drainage area and built-upon area for each pond does not exceed that which was
previously permitted: Pond 1 had a net reduction in drainage area of 1.07 acres; Pond 2 added a
portion of the former New Hanover County Library Site and deleted portions of Tracts C1 and B-1 R that
were taken for right-of-way, for no net change in drainage area.
The area that comprises Tract C3 (Recombination) must be made subject to the deed restrictions
previously recorded on January 31, 2000, in DB 2698 at Pages 0030-0046. It has been determined
that a formal permit modification is not required for the proposed changes. We previously forwarded
you a copy of the revised drainage area plans approved on April 7, 2005, for your files. Please replace
the old approved drainage area sheet with the new one dated April 7, 2005.
Please be aware that all terms and conditions of the permit issued on April 10, 2001, remain in full force
and effect. Please also understand that the approval of this revision to the approved plans fqr the
subject State Stormwater Permit is done on a case-by-case basis. Any other changes to this project
must be approved through this Office prior to construction. The issuance of this plan revision does not
preclude the permittee from complying with all other applicable statutes, rules, regulations or
ordinances which may have jurisdiction over the proposed activity, and obtaining a permit or approval
prior to construction.
If you have any questions concerning this matter, please do not hesitate to call me at [phone].
Sincerely,
Linda Lewis

STORMWATER & EROSION CONTROL CALCULATIONS
PROJECT DESCRIPTION:
The project site is located in Westfall Office Park, which is within the Wilmington City limits in
New Hanover County, North Carolina. The project site has been created by combining four (4)
existing lots within Westfall Office Park and one (1) additional lot that is not within Westfall
Office Park. The four (4) lots within Westfall Office Park are referenced as Tract C1, Tract C2,
Tract C3 and Tract C4 as shown on the enclosed survey and plans. The additional lot that is
not within Westfall Office Park is referenced as the New Hanover County Library site as shown
on the enclosed survey and plans. Therefore, the project site will be approximately 4.76 acres
after combining the following lots as mentioned above:
• Tract C1 —Westfall Office Park: 0.22 Acres
• Tract C2—Westfall Office Park: 1.00 Acre
• Tract C3—Westfall Office Park: 1.07 Acres
• Tract C4—Westfall Office Park: 1.34 Acres
• New Hanover County Library Site: 1.12 Acres
• Total Project Site: 4.76 Acres Per Recombination Survey Enclosed
The New Hanover County Library site is not currently part of Westfall Office Park project area or
drainage area to the existing Westfall Office Park stormwater ponds. However, due to the North
Carolina Department of Transportation acquiring additional right-of-way from Westfall Office
Park sites and acquiring additional right-of-way from the New Hanover County Library site, we
are proposing to add the subject site to the Westfall Office Park Pond 1 and Pond 2 drainage
area. The Westfall Office Park Pond 1 and Pond 2 drainage areas have been reduced due to
NC DOT acquiring additional right-of-way for roadway improvements on Military Cutoff Road /
SR 1409. The New Hanover County Library site can be added to the Westfall Office Park Pond
1 and Pond 2 drainage areas due to NC DOT acquiring the additional right-of-way. A revision to
the existing Westfall Office Park State Stormwater Permit SW8 990306 permits will be required
per a meeting with Linda Lewis and correspondence enclosed. Additional information on the
revised Pond 1 and Pond 2 drainage areas and required permit revisions will be provided in
following sections of the narrative.
The project site abuts two (2) existing City roads which are Sir Tyler Drive and Ashes Drive and
one (1) existing NC DOT road which is Military Cutoff Road / SR 1409. Site access will be
provided to both City roads. The project will include one (1)three story office building with paved
parking and access as shown on the enclosed plans.
EROSION CONTROL INFORMATION AND MEASURES:
Approximately 5.90 acres of the project site, Sir Tyler Drive right-of-way and Ashes Drive right-of-
way will be disturbed to construct the proposed building and onsite and offsite improvements.

zIitp
Approximately 0.35 acres of the NC DOT right-of-way will be disturbed to install a new control
access fence and for selective vegetation removal as shown on the enclosed plans. Therefore,
the total project disturbed area will be approximately 6.25 acres. The existing New Hanover
County Land Disturbing Activity/ Grading Permit No. GP 78-98 is being revised for the proposed
project. The permit revision will include the additional disturbed area associated with the New
Hanover County Library site and transfer ownership and the financial responsibility of the project
site and project disturbed area to FNB Properties, LLC.
The enclosed plans and specifications give the requirements for erosion control measures. Silt
fence shall be installed as shown on the plans. Erosion control measures will be installed
around the inlets as shown on the plans to trap silt during construction. Inspect the erosion
control around the inlets after each rain and make repairs as needed. Remove sediment as
necessary to provide adequate storage volume for subsequent rains. When the contributing
drainage area has been adequately stabilized, remove all materials and any unsuitable soil
and either salvage or dispose of it properly. Bring the disturbed area to proper grade, then
smooth and compact it. Appropriately stabilize all bare areas around the drop inlets.
Temporary graveled construction entrances will be installed as shown on the plans. Maintain
the gravel construction entrances in a condition to prevent mud or sediment from leaving the
site. The contractor shall inspect the construction entrance on a daily basis. This may require
periodic top dressing with additional stone. Any objectionable materials spilled, washed, or
tracked onto public roadways shall be removed immediately.
STORMWATER MANAGEMENT INFORMATION AND MEASURES:
Land disturbing on the site will exceed one (1) acre, which requires the site to comply with the
State Stormwater Regulations. The site will also be required to comply with a portion of the
City of Wilmington Stormwater Ordinance for stormdrain pipe sizing. The City of Wilmington
Stormwater Ordinance requires that the stormdrain pipes be sized for the 10-year storm and
checked for the 50-year storm. StormCAD stormdrain pipe calculations are attached or
enclosed for the 10-year storm and the 50-year storm. A 75% tailwater condition has been
assigned at the outlet for the stormdrain pipes draining to Pond 1 and Pond 2. The remaining
portion of the narrative will focus on the State Stormwater Regulations.
The stormwater runoff from the project site drains to two (2) existing stormwater ponds
permitted under Westfall Office Park State Stormwater Permit No. SW8 990306. The two (2)
existing stormwater ponds are referenced in Westfall Office Park State Stormwater Permit No.
SW8 990306 as Pond 1 and Pond 2. The impervious area for each drainage area is based on
85% of the lot area plus the roads associated with Westfall Office Park. The existing Westfall
Office Park drainage area to Pond 1 and Pond 2 traverse,the project site as shown on the
enclosed plans. The drainage area to Pond 1 and Pond 2 is being revised to include an
additional site referenced as the New Hanover County Library site due to NC DOT acquiring
additional right-of-way from the existing Wesffali Office Park sites for roadway improvements on
Military Cutoff Road / SR 1409. See the enclosed plans, calculations, stormwater permit
application, and stormwater pond drainage area exhibit plan for additional information.

Stormwater runoff from the project site including the building roof area will be collected and
directed to the appropriate revised Pond 1 and Pond 2 drainage area and drainage system.
The project site is allowed 85% impervious coverage. The total impervious coverage for the
project site is 70.00% or 143,930 .30 Acres. The total impervious from the project site
draining to Pon. 1 is 63.04% o : ! -s. The total impervious area from the
project site draining to Pond 2 is 71.8910 o 05,785 S 1 2.43 Acres. Based on NC DOT
acquiring additional right-of-way and the addition o he ew Hanover County Library site, the
revised drainage area to Pond 1 is 5.00 Acres and the revised drainage area to Pond 2 is
17.21 Acres, which remains unchanged. See the attached Site Data Table enclosed plans,
calculations, stormwater permit application, and stormwater pond drainage area exhibit map
and plan for additional information. Deed restrictions are being prepared for the project site
and will be submitted upon receipt from the owner's attorney.
CONSTRUCTION SEQUENCE:
The contractor will install the gravel construction entrances and new silt fence prior to
beginning any grading operations. Disturbed areas will be landscaped or seeded upon
completion in accordance with the specifications attached.

Thank you! However, I wanted to just ask if any review dates are available for Wednesday March
30, or Thursday March 31. Amy is completing the applications and supplements, etc which will be
signed today. We are closed tomorrow/Friday and I will be out Monday March 28. I would like to
review our final package prior to delivering it to Cameron. Based on our current review date this
would have to be done Tuesday morning prior to delivering it to Cameron by 9:00 AM.
If no other dates are available we will keep Tuesday March 29 and I will make it happen some
how.

Question Concerning Deed Restrictions: � 4

. odd
1. ISM-Ming troublt getting a copy of the current covenants and deed res
trictions for Westfall
Office Park. John Tunstall is not sure if he ever had a copy? Weird! Can you leave the file up front 0,
for us to review today or Monday? The attorney is on standby to prepare the revise document.
2. The current permit for Westfall does not list a breakdown of lots for each pond. It only lists a
total impervious which is referenced as the lots at 85%. I can not find anything that lists the
individual lots at 85% and Tunstall does not seem to remember. The permit also lists the road
impervious area for each pond which may not change. So, I have the drainage area to each pond 1
and pond 2 and the amount of road impervious area that will not change. I can figure the remaining
developable area based on the DA reduction and restrict it to 85% or whatever it is as long as we do
not exceed the impervious total permitted for each pond. Pond 2 drainage area ended up being the
same total as it was originally permitted, so does that one even need revising?
To complicate things further my new lot for the office building is split into two drainage areas to
pond 1 and pond 2.
I am confused! Can you provide any direction? May be the existing restrictions would help
me?

,wa: Re: W esuall Wince Yaric Revision
Cameron and I were discussing this yesterday afternoon. Since both a plan revision and
an offsite permit are needed, and plan revisions are not normally done under Express,
we decided to offer your client the opportunity to do both for a total stormwater fee of
$4000. This is $2000 for the offsite and $2000 for the plan revision. Both will done
together when you submit the Tricoast office building.
As far as required items, the Express plan revision for SW8 990306 (Westfall) will
require the fee, two sets of revised delineated drainage area maps, a listing of the
existing and proposed impervious surfaces by lot within the revised drainage area, and
proposed deed restrictions regarding the BUA limits for the lots. You will not be
allowed to revise the ponds in any way. They must be capable of meeting the design
requirements without having to increase surface area or raise the pond elevations.
For the offsite submittal, the fee, standard completed application, supplement, and two
sets of plans should suffice.

Linda,
The Tricoast Office Building Owner/Developer is FNB Properties, LLC which is
being submitted as Off site Express.
The Owner/Permittee for the Westfall Office Park Permit Revision remains
unchanged.
I assumed that it would make since to do the revision and off site permit at the
same time. I also assumed that the off site permit could not be issued until the
revision was approved. Please advise?
Please note that the revision could not be submitted until the I was done with the
The Tricoast Office Building design due to the existing and revised Pond 1 and
Pond 2 Drainage area line splitting the site and the building. It was very
complicated to grade the site and direct the building roof runoff to the appropriate
pond.
The design governed the exact location of the revised drainage area line which is
essentially the same on the site as what is currently permitted. I had to swap out an
equal size area on the site from each drainage area to get the grades to work based
on the site and building configuration. The main drainage area revision is due to
NC DOT acquiring additional right of way which allowed adding the Library Site.
Pond 1 drainage area has been reduced and Pond 2 drainage area ended up
remaining the same. It seems that I always get the complicated permitting

As you would expect, I have a lot of detailed colorful information to submit. What
exactly do we need to submit for the revision so I do not overlook something?
Please let me know your thoughts on this permitting scenario an exactly how it

I received your request for an Express review of this permit application. I need
to address one thing. The owners of the Tricoast Speculative Office Bldg. are
not the same as the owners of Westfall (at least, not on the permit). A plan
revision for SW8 990306 will need to be approved due to the changes in
drainage area and a separate offsite permit will need to be issued for the Spec.
Bldg. The offsite permit can be handled under Express, but the plan revision
cannot.
If Westfall is also owned by FNB Properties, then an ownership change and
modification to 990306 is necessary, which can be handled under Express.
Please advise as to what you want to Express.

making an informed permit decision. The permit application was deficient in the following areas: •
1. There is no concurrence from the Corps of Engineers that the Waters of the U.S.that are proposed for
impact have been identified properly. The application includes a letter from the Corps of Engineers
(USACE)indicating that there are waters of the U.S.on the site. However,there is no signed survey(or
other mapping)to indicate that the areas for proposed impact are the same areas identified by the Corps of
Engineers during their site visit. The application does include a letter dated December 22,2003 from Mr.
Jim Spangler from Spangler Environmental,Inc.to Ms.Angie Pennock of the USACE detailing the areas
that she determined the waters of the U.S. during her site visit. However,the letter appears to identify an
area of jurisdictional waters that are presently authorized as an onsite stream mitigation site for the NC
Department of Transportation's Military Cutoff Road widening project. The letter makes no reference to
the 2 drainage features that drain to the referenced stream segment(i.e.the proposed DOT mitigation site)
and are proposed for impact with the application. Furthermore,it is not clear from the application whether
the jurisdictional waters that are proposed as a mitigation site for the Military Cutoff Road project are
proposed for fill by the January 24,2005 application. Therefore,to properly process your application,the
DWQ requests that you please provide a map(or series of maps)that includes the following information:
• The entire Renaissance Park III and the Renaissance&Research Park areas. The map shall
include the entire area in question including the Renaissance Park III,the Renaissance&Research
Park,and any other developments for the same geographic area regardless of the name under
which it was authorized or proposed for authorization. The area in question includes the land area
located on the east side of Military Cutoff Road from Howe Creek south to the farthest southern
limit of the Renaissance Park III shown in your application,
• The areas of proposed widening of the Military Cutoff Road on,and immediately adjacent to,the
same properties,
• All jurisdictional waters of the U.S.on the aforementioned properties as well as the immediately
adjacent DOT Right-of-Way,

• All the identified waters of the U.S. shall be clearly labeled in regards to the field determination
made by the Corps of Engineers,
• A map signed by the USACE with all pertinent jurisdictional determinations,
• The areas of proposed onsite mitigation approved by the 401 Water Quality Certification issued to
the DOT on March 17,2004,by the NC Division of Water Quality,
• The locations of all existing and approved future culverts(see 401 Water Quality Certification
dated March 17,2004)under the Military Cutoff Road,
• All previously authorized impacts to waters of the U.S.for the entire area in question including the
Renaissance Park III,the Renaissance&Research Park,and any other developments for the same
geographic area regardless of the name under which it was authorized. The area in question
includes the land area located on the east side of Military Cutoff Road from Howe Creek south to
the farthest southern limit of the Renaissance Park III shown in your application
2. Your application received January 24,2.005 indicates that the project area in question(Renaissance Park
III)was an approved state stormwater permit previously authorized by the NC Division of Water Quality.
If this is the case,then it is likely that this project may require a modification of the existing 401 Water
Quality Certification for the Renaissance and Research Park. Certainly,in compliance with 15A NCAC 2H
.0506(c)(4)the proposed impacts for this application will need to be considered in conjunction(cumulative
impacts) with any previous impacts from the adjacent property given that they entire appears to have been
authorized by a single state stormwater permit. Please provide a copy of the issued state stormwater permit
(and corresponding mapping that displays the area approved)for the site(s)previously identified in Item 1
of this correspondence. In addition,your application,as proposed,does not include any information about
the secondary and cumulative impacts resultant from the project and their effects on downstream water
quality. Please provide an appropriate assessment of the cumulative impacts resulting from your project
and the effects that those impacts will have on downstream water quality to Howe Creek.
3. Your application received January 24,2005 fails to present the necessary information to demonstrate
appropriate avoidance and minimization has occurred on your project as it is presently designed. Until
additional information is provided that adequately addresses this issue,we cannot complete our review of
your application. Please provide a detailed explanation that details all avoidance and minimization
undertaken in developing your proposed design.
4. Your application received January 24,2005 was lacking some additional information that is required to
make a decision on your application. The areas of deficiency have been identified by a marked"X"on the
Checklist of Minimum Criteria for a 401 Water Quality Certification(attached).
Therefore,pursuant to 15A NCAC 2H.0507(a)(5),we will have to place the permit application on hold until we are
supplied the necessary information. Furthermore,until the NC Division of Water Quality receives the information,
we request(by copy of this letter)that the US Army Corps of Engineers place the permit application on hold.

•
Hopefully,we can work together to expedite the processing of your permit application. Given the complexity and
ambiguity associated with this permit application,as well as the pending litigation on the 401 Water Quality
Certification issued for the Military Cutoff Project,please direct all future correspondence to John Hennessy with
the NCDWQ. In addition,please coordinate all future communications and meetings about this application with Mr.
Hennessy. He can be contacted at 919-733-5694,or [e-mail]. Finally,to promote clarity of
communication,the NC Division of Water Quality would like to be invited to any site visits that might be
coordinated with the USACE. We appreciate your cooperation while we work through the processing of your
application.

John:
I have received concurrence from Central Office staff that the application should
be considered a plan revision, with the new drainage area boundary shown. You had
indicated to us that your intent is to remove the right-of-way area taken by DOT
for the widening of Military Cutoff Road and add the former library site to the
drainage area. This is acceptable as a plan revision, as long as the new drainage
area is less than or equal to the existing drainage area, and no more built-upon
area than is currently permitted will be constructed within the new drainage area.
This decision is based on the information you provided at our meeting where you
indicated that the former library lot was just barely over an acre in size after
the taking of right-of-way, and could easily have disturbed less than 1 acre, and
not been required to submit for state stormwater. A hardship was created when the
DOT imposed controlled access on Military Cutoff, which landlocked the former
library lot. If either of these conditions is not the case, this agreement is null
and void.
Both the ability to provide treatment for the runoff from the former library lot
where none might have been, and the hardship created by DOT's controlled access
restrictions on Military Cutoff, are special circumstances that were considered in
making the decision to allow a change to the drainage area without a formal permit
modfication.

Linda,
I spoke with Bradley today about the Westfall Office Park. We concur that the best
thing to do here is to revise the permit as you suggest. Bradley's perspective is
that since the original permit was issued under the previous directive (even though
it has been rescinded) , the permittee doesn't need to try to modify their project
to comply with the requirements we would otherwise implement today.

Hello all:
I had a meeting with John Tunstall, P.E. of Norris, Kuske & Tunstall, who is the
consultant for a group of developers who bought some property in the permitted
subject commercial office park. The office park is across Military Cutoff from
Mayfaire, and drains to Howe Creek.
The permit for Westfall was issued prior to rescission of the 4th Directive
regarding the chlorides testing for SA waters. Based on the chlorides test, which
indicated freshwater 1/2 mile downstream from the project, the project was
permitted for 4 detention ponds. The ORW waters of Howe Creek had been determined
to be "freshwater", and therefore subject to NCAC .1007 (1) (b) , which allows wet
detention ponds, and does not require low density within 575' .
Military Cutoff is being widened. NCDOT took a large swath of right-of-way in front
of the permitted office park, and has established controlled access. This
right-of-way is within the permitted drainage area of Westfall's ponds. A 2.1 acre
tract of land fronting Military Cutoff was excluded from the Westfall project area
because it had been donated to the County for a new library. The County ended up
selling the lot and using another tract for the library. Access to the 2.1 acre
former library lot was cut off by the taking of the ROW, reducing the tract acreage
to 1.125 acres.
The group that John Tunstall represents would like to bring in the former library
lot to the drainage area for this permit and exclude the right-of-way (over 2
acres) that was taken and which will not be draining to the permitted ponds. The
former library lot would be added to other lots that they currently own in the
office park to create one development, all draining to the previously permitted
ponds. The total drainage area and built-upon area will be reduced from what was
permitted. All of the drainage from the development will drain to ponds that
currently exist under the permit.
Problems arise in the re-permitting of the wet ponds due to the fact that if the
project were getting a new permit today, we would require infiltration and low
density within 575' of Howe Creek. If we don't revise the permit to include the
former library site, it could conceiveably disturb less than 1 acre and not be
required to get a permit from us (i.e. , no water quality treatment at all, with
runoff going directly into Howe Creek) .
If we revise the permit to allow the swap of drainage area, and keep the wet ponds,
we will at least have gotten treatment of an area that would not have been subject
to state stormwater requirements, otherwise. Because of the hardship created by
the controlled access, I am seeking your concurrence that a plan revision is the
best option. All parameters of the permit remain the same, except that the BUA is
laid out differently, or in this, the drainage area boundary will change to exclude
one area and bring in another. Everything else about the permit remains the same.
Please advise ASAP if you concur. Thanks,
Linda

From: Linda Lewis<[e-mail]> 2(7

To: John Tunstall<[e-mail]> _
John:
I corresponded with Central Office staff and we agree it's OK to pursue
the option of adding new drainage area to the existing permitted Pond 4,
while keeping the overall amount of permitted built-upon area the same
by reducing the BUA per lot on the permitted lots in the existing
drainage area and giving it to the new development in the additional
drainage area.
The surface area of the existing pond may not be expanded to accommodate
this modification. The Division will allow a slight change to the
temporary storage elevation to accommodate minor volume increases, due
to the larger drainage area, if necessary. Hopefully, the pond as
currently exists will accommodate the new drainage area without any
modification at all.
Additionally, the deed restrictions for the development within the new
drainage area will need to be tied into the existing project. I'm not 101
exactly sure what the intent is here, but I will assume that the new
drainage area to be added is an expansion of the same project and will .1117
be considered another phase of the project, therefore, it can be made
subject to the same master restrictions and covenants that should be in
place for the existing development. Since the currently permitted BUA's
will be changing, be sure to include a copy of the amended covenants
when you submit the application.

Talked to BB (How's that for a fast response?).
He's okay with the proposal, with two caveats (of course!). If they haven't done so already, the permittee
will need to:
1. Supply sufficient calculations to that show the ponds current size is sufficient to treat the old drainage
area and the new additional drainage area. (For this to work, I assume the pond was initially oversized)
2. Supply documentation(deed restrictions language) showing the new BUA limits are tied to the old
and new drainage area.
I suspect you have number one in hand already and you will require number two,but BB wanted to make
sure the issues where noted.
Hope this helps!
Have a good weekend-Hopefully you'll have at least one dry day, it's suppose to rain here Sat and Sun

Let me make sure I understand what their proposing before I talk to BB.
The office park project is currently permitted for 85% BUA for some X
acre drainage area. They want to tie in additional drainage area, which
I assume is undeveloped. This will bring the BUA % down to say 60% BUA
for the newly created drainage area (old plus new), then they want to
build some project in the newly added drainage area. The new project
will raise the BUA % for the entire project back up to approx. 70%.

Re:990306 Westfall Office Park
In this mix and match situation, I'm also assuming the runoff volumes
come out a wash. True?
Is that the general idea?

Add this to your list of questions for me.
Westfall Office Park was permitted in 1999, before the repeal of the 4th
directive as high density with wet detention ponds. They are located on
the downstream side of Howe Creek from Mayfaire, across Military Cutoff.
But, their development was totally outside of the 575' ORW AEC.
One of the ponds is permitted for a drainage area that is 85%
impervious. The engineer wants to add more drainage area to this pond by
reducing the impervious area 13%-15% within the permitted drainage area
and giving it to the new drainage area. The result is an increase in
drainage area, no net increase in BUA and no modifications to the
existing pond. We allowed this very same thing at Landfall with a new
retirement center. They reduced the BUA on the single family lots that
were already a part of the drainage area by an amount sufficient to
cover the new BUA from the retirement center. Because of the ORW and
Howe Creek and Mayfaire stuff going on, I thought I needed to go through
you before I say it's OK. I don't have a problem with it.
At this same site, if the above will not be allowed, can the
infiltration basin for the high density development outside the 575' AEC
be located inside the 575' AEC, as was done at Mayfaire, if the soils
are suitable?
Many thanks for your guidance, and have a great weekend.
