RE: Request for Additional Information
Stormwater Project No. SW8 060553
Porter's Pointe Subdivision
New Hanover County
Dear Christine,
Please find the following responses to your Request for Additional Information dated June 7,
2011 for the above referenced project.
1. On June 6, 2011, we provided documentation verifying that Jennifer D. Smith has the
authority to serve as an officer for First Troy SPE, LLC.
This document was signed by Teresa C. Nixon, Eric P. Credle, and Kimberly S. Harrison
all of which are Managers of First Troy SPE, LLC as indicated on the attached sheet
printed from the NC Secretary of State website.
Section Ill. La of the Stormwater Application has been revised to list a Manager of the
LLC. Also, Section 111.I.b of the Stormwater Application has been revised to reflect the
contact information of the Manager.
2. Rip -Rap lining has been designed to harden the existing basin side slopes where slopes
are steeper than 3:1. The basin section views on sheet SW-2 have been revised to show
the addition of rip -rap.
I trust that this information is sufficient to review and approve the modification for the subject
stormwater permit. However, if you have any questions or need any additional information please
do not hesitate to contact me.

Subject: Second Request for Additional Information
Stormwater Project No. SW8 060553
Porter's Pointe Subdivision
New Hanover County
Dear Ms. Smith:
Dee Freeman
Secretary
The Wilmington Regional Office received a modified Express Stormwater Management
Permit Application for Porter's Pointe Subdivision on May 19, 2011 with additional
information received on June 6, 2011. A preliminary review of that information has
determined that the application is not complete. The following information is needed to
continue the stormwater review:
The signing official and permittee identified in Section Ill.1.a of the
application must be from a manager of the manager -managed First Troy
SPE, LLC per 15A NCAC 2H.1003(e). To ensure the applicant is a
manager of the LLC, they must be either registered with the NC Secretary
of State or official supporting documentation from the LLC must be
provided.
If signatures by a person other than the manager are desired on the
application and associated documents (such as Operation & Maintenance
agreements), then a signed letter of authorization from the manager must
be provided which includes the name, title, mailing address and phone
number of the applicant. The manager must still be listed in Section of
111.1.a of the application.
Please correct the application and any additional documents. If
necessary, please provide any supporting documentation.
2. All vegetated side slopes must be no steeper than 3:1 per 15A NCAC
2H.1008(c)(2). The infiltration basins were originally approved under the
premise that the side slopes were 3:1. If side slopes steeper than 3:1 are
desired, then the side slopes may be hardened with an appropriately
designed alternative, such as a retaining wall.
3. The express additional information fee has been waived for this request
for additional information. Please be advised that typically only two
requests for additional information are allowed. If these items are not
appropriately addressed, the project may either be returned or, in special
circumstances, the supervisor may approve a third request. If a third
request is found to be necessary, then a fee will likely be assigned.

Please keep in mind that changing one number may change other
numbers and require the calculations, supplements, and other supporting
documentation to be updated. Verify all numbers are correct to ensure
consistency in the application documents.
Please note that this request for additional information is in response to a preliminary
review. The requested information should be received in this Office prior to June 16,
2011, 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 email or fax your request
for a time extension to the Division at the address and fax number at the bottom of this
letter. Please note that a second significant request for additional information may result
in the return of the project. If the project is returned, you will need to reschedule the
project through the Express coordinator for the next available review date, and resubmit
all of the required items, including the application fee.
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 label all packages and cover letters as "Express" and reference the project
name and State assigned project number on all correspondence. If you have any
questions concerning this matter please feel free to call me at [phone] or email
me at [e-mail].

RE: Request for Additional Information
Stormwater Project No. SW8 060553
Porter's Pointe Subdivision
New Hanover County
Dear Christine,
Please find the following responses to your Request for Additional Information dated June 1,
2011 for the above referenced project.
1. Documentation verifying that Jennifer D. Smith is the registered agent for First Troy SPE
has been included with this submittal of additional information.
2. Based on our review of the approved permit file, it appears that the basin slopes were
incorrectly reported as 3:1 on both the basin section views and basin supplements. The
permitted basins were designed and constructed with 2:1 contours as shown by the
proposed contours on the approved plan set.
CFE has obtained the electronic drawing files from the original engineer and can verify
that the originally permitted surface areas and volumes used for water quality and routing
calculations correspond to the 2:1 contours shown on the approved plans.
Please recall that the proposed modification does not alter the approved infiltration basin
elevations, surface areas, or volumes. Therefore, the proposed modification still includes
2:1 slopes inside of the infiltration basins. Pages I of the infiltration basin supplements
have been revised to reflect Basin Side Slopes of 2:1.
It should also be noted that the majority of the basin slopes, which were constructed in
late 2006 with 2:1 contours, are vegetated and stable. There are a few areas of minor
erosion that will be repaired and vegetated prior to certification.
1 trust that this information is sufficient to review and approve the modification for the subject
stormwater permit. However, if you have any questions or need any additional information please
do not hesitate to contact me.
Sincerely
Matthew

Dear Ms. Smith:
The Wilmington Regional Office received a modified Express Stormwater Management
Permit Application for Porter's Pointe Subdivision on May 19, 2011. 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 confirm and, if necessary, correct the information presented in
Section 111.1.a of the application. With the property owner being First Troy
SPE, LLC, the signing official listed on the application must be from a
manager the manager -managed LLC per NCAC 2H.1003(e); however,
Section Ill.1.a of the application lists the signing official as the Senior Vice
President. To ensure the applicant is a member or manager of the LLC,
they must be either registered with the NC Secretary of State or official
supporting documentation from the LLC must be provided.
If signatures by a person other than the manager are desired on the
application and associated documents (such as Operation & Maintenance
agreements), then a signed letter of authorization from the applicant
(manager) must be provided which includes the name, title, mailing
address and phone number of the applicant. The manager should still be
listed in Section off 111.1.a of the application.
2. Plan sheet SW-2 indicates that the infiltration basins will have side slopes
of 2:1. Other documentation submitted indicates these side slopes will be
3:1. Additionally, the infiltration basins were previously approved with side
slopes at 3:1. Please ensure the basin side slopes are at 3:1 and update
the plans.
3. The express additional information fee has been waived for this request
for additional information.
4. Please keep in mind that changing one number may change other
numbers and require the calculations, supplements, and other supporting
documentation to be updated. Verify all numbers are correct to ensure
consistency in the application documents.

RE: Porter's Pointe Subdivision

DWQ Stormwater Permit Number: SW8 060553
Narrative for Express Stormwater Review
Dear Christine,
On behalf of First Troy SPE, LLC, Cape Fear Engineering is submitting to modify the Stormwater
permit for the above referenced project.
Existing Permit Info
This project was originally permitted on July 17, 2006 and subsequently modified on December
19, 2006 as SW8 091111. The original project included two infiltration basins designed to treat
and handle runoff from 61 single family lots, one future amenity site, roads, sidewalks, and
alleyways.
Proposed Modifications
The purpose of the proposed permit modification is to address several as -built conditions that are
inconsistent with the approved permit, to incorporate several minor revisions to the landplan and
to change the project ownership. The individual modifications are described below.
• Under the December 19, 2006 modification, Lots 40-44 were to be filled so that they
drained towards Shackleford Drive and ultimately Infiltration Basin A; however, as -built
information shows that these lots drain to a collection system in the alleyway at the rear
of the lots which discharges to Infiltration Basin B.
• Lots 16 & 17 (each previously permitted for 4,015 sf of BUA) have been combined into
a single Lot 16R with 5,000 sf of BUA.
• Lots 29 & 30 (each previously permitted for 4,015 sf of BUA) have been combined into
a single Lot 30R with 5,000 sf of BUA.
• 10,000 sf of Reserve / Future impervious has been added to each Drainage Area
• First Troy SPE, LLC has acquired this project from the original owner. Therefore, the
modified permit will need to be in the name of First Troy SPE, LLC.
A
PE Certification
✓
oN
To date, only a portion of the originally permitted improvements have been completed. Currently
q
constructed improvements include all roadways, some sidewalks and alleys, and three single
family houses.
gBecause
of the proposed modifications described above, the project is not in compliance with the
existin t nd therefor is uunallle tgPug ified at tl�is)j3i�e.1044 •FAX: [phone]

The proposed permit modification is intended to address the non -compliant items. A Final PE
Certification will be prepared and submitted upon approval of the permit modification.
Soils Information
This modification relies on the soils report prepared by S&ME dated May 16, 2006 and the field
investigation of Vincent Lewis ofNCDENR-DWQ. No additional geotechnical investigations
have been performed.
Water Quality Calculations
Because this project was originally permitted under the Coastal SW — 1995 rules, the previously
permitted drainage and impervious areas for each basin are vested and therefore, the required
storage volume for these areas is the 1.5" storm event only.
Any increases in drainage or impervious areas for each basin are NOT vested and therefore, the
required storage volume in these areas is the larger of the 1.5" storm event or the difference in
pre -post runoff volume for the I -year 24-hour storm event.
Both the vested and non -vested portions of each drainage area have been defined and the required
storage volume for each area has been calculated to demonstrate that the proposed modifications
do not affect the infiltration basins' ability to treat and infiltrate the required storage volume
within a period of 5-days.
Revised Infiltration Basin Sizing Calculations can be found in Attachment A of the attached
calculations.
Pre -Post Attenuation
Because this project was originally permitted under the Coastal SW — 1995 rules, the previously
permitted drainage and impervious areas for each basin are vested and therefore, these areas are
not required to meet pre -post attenuation for the I -year 24-hour storm event.
Any increases in drainage or impervious areas for each basin are NOT vested and therefore, these
areas are required to provide pre -post attenuation for the I -year 24-hour storm event.
Due to the complexity of the routing the vested and non -vested areas separately, routing
calculations for the entire drainage areas have been provide to demonstrate that pre -post
attenuation requirements for the 1-year 24-hour storm have been met.
Revised Routing Calculations can be found in Attachment B of the attached calculations.
Level Spreaders & Vegetated Filter Strips (LS & VFS)
AThe
originally approved routing calculations used to size the level spreaders and vegetated filters
wwere
performed using the SCS Synthetic Distribution for a 6-hour storm duration. Revised
o
routing calculations using the SCS Type III Distribution for a 24-hour storm duration have been
rnperformed
to size the level spreaders and vegetated filters under the proposed modification.
Additionally, the originally approved design had the vegetated filter upstream of the level
a
spreader. The proposed modification has re -configured the level spreader and vegetated filter
�ry
strips so that the modified design meets the current NCDENR BMP Manual. (ie level spreader
located at pipe outlet and upstream of vegetated filter strip).

Based on the level spreader and vegetated filter strip length requirement of 10-ft per cfs, Basin A
requires an 11.5-11 level spreader and vegetated filter strip and Basin B requires a 0-11 level
spreader and vegetated filter strip.
It should be noted that because Basin B does not meet the criteria of the NCDENR BMP Manual
Chapter 16 for waiving the bypass and filter strip requirement for infiltration basins, a 10-ft level
spreader and vegetated filter strip have been provided.
Emergency Spillways
The originally approved design had the emergency spillways at the same location as the vegetated
filter and level spreader. Therefore, during larger storm events the emergency spillway would
discharge through the vegetated filter and across the level spreader.
Due to the high potential for larger storm events to cause significant erosion in the vegetated filter
and around the level spreader, the proposed modification includes relocating the emergency
spillways away from the level spreaders and vegetated filters.
The proposed emergency spillways have been designed for grass ground cover only. Calculations
demonstrating that the 10-year storm flow through the emergency spillways is non -erosive have
been included in Attachment C.
1 trust that this information is sufficient to review and approve the modification for the subject
stormwater permit. However, if you have any questions or need any additional information please
do not hesitate to contact me.

RE: Porter's Pointe Subdivision
New Hanover County
DWQ Stormwater Permit Number: SW8 060553
Narrative for Express Stormwater Review
Dear Janet,
On behalf of the First Bank, Cape Fear Engineering is requesting an Express Stormwater Review
for the modification of the stormwater permit for the above referenced project.
Existing Permit Info
This project was obi inall permitted on July 17, 2006 and subsequently modified on December
19, 2006 as SW8 99 Me original project included two infiltration basins designed to treat
and handle runoff from 61 single family lots, one future amenity site, roads, sidewalks, and
alleyways.
Proposed Modifications
The purpose of the proposed permit modification is to address several as -built conditions that are
inconsistent with the approved permit, to incorporate several minor revisions to the landplan and
to change the project ownership. The individual modifications are described below.
• Under the December 19, 2006 modification, Lots 40-44 were to be filled so that they
drained towards Shackleford Drive and ultimately Infiltration Basin A; however, as -built
information shows that these lots drain to a collection system in the alleyway at the rear
of the lots which discharged to Infiltration Basin B. i
• Lots 16 & 17 (each previously permitted for 4,015 sf of BUA) have been combined into
a single Lot 16R with 5,000 sf of BUA.
• Lots 29 & 30 (each previously permitted for 4,015 sf of BUA) have been combined into
a single Lot 30R with 5,000 sf of BUA.
• 10,000 sf of Reserve / Future impervious has been added to each Drainage Area
• First Bank has acquired this project from the original owner through foreclosure.
Therefore, the modified permit will need to be in First Bank's name.
PE Certification
To date, only a portion of the originally permitted improvements have been completed. Currently
constructed improvements include all roadways, some sidewalks and alleys, and three single
family houses.
Because of the proposed modifications described above, the project is not in compliance with the
existing permit and therefore, is unable to be certified at this time. i �+
MAY 0 2 2011
P.V50750-05 FB-PORTERS MWE SDWdmmWOR.%1W NCDEI1R proms ScWing Ns umvd

The proposed permit modification is intended to address the non -compliant items. A Final PE
Certification will be prepared and submitted upon approval of the permit modification.
Soils Information
This modification relies on the soils report prepared by S&ME dated May 16, 2006 and the field
investigation of Vincent Lewis of NCDENR-DWQ. No additional geotechnical investigations
have been performed.
Infiltration Basin Geometry
In order to meet New Hanover County's freeboard requirement for the 100-year storm event, the
emergency spillways have been widened. All other dimensions, elevations, surface areas, and
volumes remain unchanged from the previously permitted values.
Water Quality Calculations
Because this project is vested under the Coastal SW — 1995 rules, the infiltration basins have been
designed for the 1.5" storm event only. The infiltration basins are not required to hold the
difference in the pre -post volume from the 1-year 25-hour storm event.
Revised infiltration basin water quality calculations have been prepared to demonstrate that the
Proposed Modifications do not affect the infiltration basins' ability to treat and infiltrate the water
quality design storm within a period of 5-days.
Revised Infiltration Basin Sizing Calculations can be found in Attachment A of the attached
calculations.
Pre -Post Attenuation
Because this project is vested under the Coastal SW — 1995 rules, the infiltration basin is not
required to attenuate the peak Bow for l-year 24-hour storm to meet State Stormwater
Regulations.
However, New Hanover County Stormwater Regulations require peak flow attenuation for the 2-
year, 10-year, and 25-year 24-hour storms.
Revised Routing Calculations can be found in Attachment B of the attached calculations
Level Spreaders & Vegetated Filter Strips (LS & VFS)
Revised routing calculations for the 10-year storm indicate that for both Infiltration Basin A and
Infiltration Basin B, the expected discharge to the level spreader and vegetated filter is less than
the originally permitted values. Therefore, no modifications are required to the previously
permitted level spreaders or vegetated filter strips.
