Mr. King,
was given your contact information by Ms. Natalie Berry, Henderson County. I did try to contact you at (828)243-0087,
but got an incorrect number, so I am sending you an email. I am contacting you concerning an existing state
stormwater permit for the Braewood Subdivision located in Henderson County. My understanding is that you are now
owner of this property. This project, previously permitted as Braewood Subdivision, has a state stormwater permit
issued to Mr. Hilton Swing for post -completion stormwater. I have attached the permit for your review, and would
encourage you to come and review our files including the approved plan if you do not have one on file. If you are
planning on completing this development as permitted you will need to transfer the existing stormwater permit to your
name using the attached form. If you are going to development a different plan than what is currently permitted, you
will be required to apply for and receive a Post -Construction Stormwater permit from Henderson County. Ms. Natalie
Berry can assist you with this process. If you have any questions regarding transferring the stormwater permit, please
contact me at either the telephone number below, or by email.
In addition, it is my understanding that some land -disturbance (logging) has taken place on the site. If the location of
the wetlands has not been marked in the field, this should be done prior to any additional land -disturbance at the
site. There may also be additional requirements through the Division of Water Resources (Tim Fox) and the US Army
Corp of Engineers (William Elliott) regarding the development of this property because of the wetlands. You are
encouraged to contact these folks for this information. I have copied both on them on this email.
We appreciate your cooperation in these matters, and look forward to working with you.

Dear Mr. Morgan,
It has come to the Corps of Engineers attention that Morgan Family Investments, LCC has
recently purchased and plans to develop the Braewood tract at 1094 West Blue Ridge Road in
Flat Rock, Henderson County North Carolina. The Department of the Army (DA) issued a
general permit verification authorizing impacts to waters of the U.S. (WoUS) at this property in
April 2010 (Action ID 2006-40018) to the previous owner of the property for activities
associated with construction of a residential development. This permit verification has expired
and none of the authorized impacts were been constructed.
The purpose of this letter is to notify you there is no valid DA permits for impacts to WoUS
at this property. Please be aware, the past permit verification required restrictive covenants for
conservation areas to be established on the property and to maintain these areas in their natural
state in perpetuity. The covenants were to aid in the protection of a significant Southern
Appalachian Bog ecological community.
Any work at this property which will result in impacts to jurisdictional WoUS may require
DA authorization pursuant to our regulatory authority under Section 404 of the Clean Water Act
(CWA). Under Section 404 of the CWA, DA authority regulates discharge of dredge or fill
material into WoUS. Activities involving the discharge of fill material in WoUS without
authorization by a DA permit are a violation of Section 301 of the Clean Water Act (33 U.S.C.
1311). If you have any questions, please contact me at (828) 271-7980 extension 232.

Anita,
See the attached copy of the first couple of pages of the SW permit (issued November 5, 2008) and an overview of the
approved plan (with the wetlands outlined in blue). The new owner needs to transfer the permit and needs to follow
the approved SW plan. We have a copy here in ARO, in case he does not have a copy. This was permitted as a post
construction 5W permit, so I am trying to run down the history on that. (Natalie, you may can provide some historical
perspective on this?). Are they just now clearing for the subdivision? Anita, if you have the current owner's contact
information, we can contact him directly to discuss his responsibilities wrt the stormwater permit.
Thanks,

Subject: King Creek Bog Location/ Landowner Map and Braewood Development Plan as requested for Permit SW-
1080802
1-11 Laura,
Thanks for looking into permit for this so we might review the stormwater plans for this development. King
Creek Bog is owned by three entities. Matt King/Morgan Family Investments recently purchased Braewood
failed development at auction (once owned by Swing/then `TD Bank foreclosed). The maps attached focus on
the Potts property (they own a significant portion of the bog), where we are funding a bog
restoration/management project. We have also funded management for invasive, exotic plants on Rick Merrill's
property (also part owner of King Creek bog) in past years.
We are very concerned about storm water/contaminants entering bog, changing the chemistry of site (bogs are
nutrient poor), and impacting negatively rare species. This bog contains occupied habitat significant for two
rare plants that are critically endangered and protected under the Endangered Species Act. If you have an
approved plan that we can review, it will help us to determine the type of impacts we might expect from this
development, and we hope in the future to work with the developer and future landowners to reduce these
impacts to King Creek bog. Note that the FWS restoration program I oversee focuses on mountain bog
management and conservation, and may offer incentives to landowners (technical assistance and funding) to
restore and manage mountain bogs, and as well as treat stormwater through LID practices, on their property.
Please let me know if you need anything else from me. If you plan to visit the site and would like someone
from this office to accompany you, please let me know.
Thanks Laura,
Anita

Mike,
As a follow-up to our conversation regarding the stormwater management plan for the subject project, we have
made several revisions to our plan in effort to address your comments provided in your August 28th letter. While
several of your comments (comments 1-3) pertained specifically to the wet detention pond we are proposing for
Phase III of this project, comments 4 & 5 addressed issues critical to enable us to permit this project as a
low -density development. Based your comments and our follow-up conversation, the specific issues at hand with
regards to permitting this project as a low -density development dealt with transporting the stormwater runoff
through natural or vegetated conveyances.
Upon taking another took at the project, we do not have any problems with satisfying your comments regarding the
wet detention pond. Relative to the stormwater conveyance, we have taken another look at the project and have
found several areas where it was practicable to utilize grass swales & ditches as opposed to storm drain culverts
as originally proposed. In our prior conversation, we discussed two areas of primary concern where we needed to
evaluate this. I'm pleased to say that I think we have sufficiently addressed one of these areas and while we do
have some limited options for the other area, the options are less than ideal and we feel would adversely impact
the character of the development. I hope you'll find that the changes we have made will provide you the
comfortable level you need to move forward with the low -density permit.
In the event you still have reservations towards treating this as a low -density development, it would obviously
greatly affect the permit application and final design. As we discussed, to avoid any further time and delay to this
permitting process, we would like to resubmit our revised plans to you as a preliminary submittal. While we feel we
have sufficiently addressed your comments, we would like your concurrence prior to revising our drainage
calculations and report. I will be forwarding these preliminary plans for your review with a more detailedsummary
of the changes we have made and specifically how we have addressed your comments. You should receive these
plans early next week.
We certainly appreciate your cooperation and flexibility in working with us on this project. If we determine we have
properly addressed your concerns with these plan revisions, we will provide you with a formal resubmittal of the
project promptly upon getting your concurrence.

Hi Mike:
Hope you are well?
I have looked over the Army Corps application for utility crossing of wetlands in
order to install stormwater ponds for the Braewood project.
It appears that the stormwater features will be installed right on the edge of the
adjacent creek and the piping will have a strong possibility of draining the wetland.
Ed Swartzman (Natural Heritage Program) has reviewed the site and found both state
and federal species (plant and animal) in these wetlands (including a single shrub
species where it is the only known population in the state).
The installation of these utility crossing to facilitate stormwater management will
likely impact / remove the best use of the wetland and eliminate the existence of
these threatened and endangered species.
Due to the project only being a utility crossing, depending on which Nationwide
Permit is issued by the Army Corps of Engineers, the State will likely have no input
into this project from the 401 program. We are awaiting a decision from the Corps on
this.
After a review of the plans, it appears that creative / alternative stormwater
treatment facilities (such as rain gardens) can be implemented while eliminating the
need for several of the floodplain wetland impoundments.
Please feel free to contact me when you see the application for this project.
Best regards,
Kevin

Subject: Request for Additional Information
Stormwater Project No. SW 1080802
Braewood Subdivision
Henderson County
The Division of Water Quality Central Office received a Stormwater Management Permit
Application for the subject project on August 5, 2008. A preliminary review of that information
has determined that the application is not complete. The following information is needed to
continue the stormwater;review: .
1. Please provide information on how the SHWT was established. Information on the
seasonal high water table (SHWT) need to be provided. If the SHWT is below the
permanent pool elevation (PPE), then a liner will need to be provided in order to
maintain the permanent pool. If a clay liner is proposed, then a minimum 4-inch
layer of topsoil shall be provided on the vegetated shelf for planting.
2. Please provide a detailed landscaping plan for wet pond. The planting plan must be
prepared by a qualified design professional licensed in North Carolina. The
landscaping plan for a stormwater wet detention basin should provide specifications
for the selection of vegetation, its installation, and the post -installation care for the
vegetated shelf, the 3:1 side slopes, the vegetative filter strip, and the immediately
surrounding areas.
3. The orifice configuration provided does not provide for adequate maintenance access.
With the "tee" type configuration, the small orifice opening should be provided at the
bottom of the "tee" underwater so that a rod may be used to unclog it.
4. Please provide details of road B, curb outlet systems and swales. Side slopes of
conveyance swales not seeking credit removal must be no steeper than 3:1. (See
BMP Manual Chapter 14, page 14-3. Sheet 5 of 5 shows a 2:1 slope).

5. The project does not meet the low -density requirement to transport stormwater runoff
primarily through vegetated conveyances. Low -density projects should not have a
discrete stormwater collection system as defined by 15A NCAC 2H.1002(18). Under
' I5A NCAC 2H 1002(18) a stormwater collection system means any conduit, pipe,
channel, curb or gutter for the primary purpose of transporting runoff.
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 October 3, 2008, 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. 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

Re: Braewood Subdivision
Flat Rock, North Carolina
Dear Mr. Randall:
Pursuant to your letter dated October 1, 2007, Florence and Hutcheson, Inc. hereby respectfully
submits the following application for a post -construction stonmwater permit for the Braewood
Subdivision. This project located in Henderson County, North Carolina within the corporate limits
of the Village of Flat Rock. We recently received approval for the sediment and erosion control
permit for this project on March 31, 2008 (Project ID: HENDE-2008-011).
With this application, I would like to offer a brief summary of the project and several activities that
have guided the direction of the stormwatet management plan. The Braewood Subdivision is a
residential subdivision of approximately 90 acres into 122 residential lots. The project is proposed
to be constructed in three consecutive phases. This project has been approved by the Village of Flat
Rock as residential planned unit development in which 50% of the site will be preserved as open
green space. Within the project site are several wetlands which comprise 7,57 acres of this green
space area. The intent of this application is to secure the post -construction stormwater permit for
the entire project.
The project was originally developed with four separate detention ponds for water quality and
quantity requirements. However, at an on -site meeting between Mr. Clement Riddle of ClearWater
Environmental Consultants, Inc., USACOE, US Fish & Wildlife, and the NC Wildlife Resource
Commission on February 20, 2008, there was a general concern among the regulatory agencies with
two of the proposed detention ponds. The purpose of this particular meeting was to discuss a permit
application submitted by ClearWater Environmental for utility crossings in several of the wetland
areas and during the review of the project, it was determined that the two detention ponds may
potentially affect the wetlands within that area. In effort to alleviate these concerns and preserve
these wetlands, an alternate plan providing water quality and utilization of the wetlands was
discussed with a favorable response from USACOE. This alternate plan essentially replaces the
two detention ponds with level spreader/filter strips to provide stormwater treatment prior to
16 Wetlington Avenue • Greenvitle, SC 29609 • (864) 233-5425 • Fax (864) 233-5435
entering the wetlands. A conceptual design of this alternate plan was recently presented to you by
Mr. Riddle, ClearWater Environmental, via email, on May 5, 2008. Following your phone
conversation with Mr. Riddle on May 12, 2008 and with your verbal approval of the conceptual
plan, we have performed the final engineering and developed the final stonnwater management
plan accordingly which is presented with this application.
Our intent with this project is to develop a stormwater management plan that achieves a
satisfactorily level of water quality while also preserving the natural wetlands located on the site.
We appreciate your review of this application and welcome the opportunity to discuss the project in
detail with you, as well as explore other opportunities available to meet the water quality
requirements. If you have any questions or would like to meet to discuss, I can be reached at (864)
233-5425.

Re: Stormwater Project No. SW 1080802
Braewood Subdivision
Dear Mr. Randall:
As a follow-up to our recent conversations and the comments received in your August 28`l'
letter regarding the post -construction stormwater permit for the Braewood Subdivision, Florence
and Hutcheson hereby respectfully submits revised stormwater management plans on behalf of Mr.
Hilton Swing for your review. As you recall, this residential development is occurring on 90 acres
of land, in which 50% of the site will be preserved as green space. The site also has several
jurisdictional wetlands and our intent is to permit this project as a low -density development in order
to preserve the site and avoid adverse impacts to the wetlands. Upon review of our application,
however, you identified several concerns relative to certain aspects of the proposed improvements
which do not meet the requirements of a low -density development.
We have since taken another look at the proposed improvements and revised the plans in effort to
alleviate these concerns. In response to our previous conversations and your preliminary review
comments, 1 offer the following summary of the revisions that have been made to satisfy the
conditions of a low -density development permit.
1) Per our conversation, we have eliminated Wet Detention Pond 91 from the project. This
pond was initially proposed for Phase I of the project in close proximity to a wetland. Since
this phase achieves the requirements of a low -density development, the pond is not required
for water duality and therefore has been removed.
2) Comments 1-3 of your August 281h letter were concerned specifically with the Wet
Detention Pond design. While these revised plans do not specifically address your
comments at this time, we have no objection and can properly satisfy these concerns upon
determining the final pen -nit application type. In general, our formal resubmittal of the
application will include a detailed landscape plan prepared by a North Carolina licensed
professional with specifications and a maintenance plan developed to the Department of
16 Wellington Avenue • Greenville, SC 29609 • (864) 233.5425 • RLx (864) 233-5435
Water Quality standards. Additionally, a rubber liner will be proposed for the ponds in order
to maintain the permanent pool for the pond. The outlet structure detail -will be revised to
provide an orifice design satisfying the maintenance requirements.
3) Comments 4-5 of your letter dealt with issues relative to meeting the stormwater
conveyance requirements of a low density development. These comments were specifically
related to two areas of Phase II of the project where we were proposing curb and gutter and
storm drain culverts as the means of conveyance. Per our conversation, we were instructed
to provide the stormwater conveyance to the maximum extent practicable by means of
vegetated swales. After taking another look at the project, we determined that we could
utilize vegetated swales in lieu of the culverts in one of these areas. The revised plans reflect
where these swales are proposed. With this change, we have eliminated approximately 800
linear feet of storm drain pipe. Additionally, the stormwater runoff from 19 lots (27.5%)
within this phase will now be conveyed primarily through a grass swale. While other
locations within this phase where analyzed for similar revisions, changes were not
implemented due to impacts to the residential lots and the overall character of the
development.
We hope you will find that we have sufficiently addressed your concerns for meeting the
requirements of a low -density development. Obviously, if these revisions do not alleviate your
concerns, it will greatly affect the post -construction permit application for this project. We
appreciate your willingness to provide another preliminary review of these revisions prior to
making whole -scale revisions to our drainage report, calculations, and design. Our intent with this
project is to develop a stormwater management plan that achieves a satisfactorily level of water
quality while also preserving the site as much as possible. We certainly appreciate your
cooperation and flexibility in working with us on this project. If determined we have properly
addressed your concerns with these plan revisions, we will provide you with a formal resubmittal
of the project promptly upon getting your concurrence.

Laura,
The roads are in partially and gravelly. Hilton Swing went bankrupt and lost everything. Matt King bought the
property and asked to log a little less than one acre of trees on the roadway edges. I allowed this ( not sure it
was a good idea in hindsight ) for the owner. I did not know about the bog or the Existing stormwater plan and
I believe the logger may have gotten carried away. i stopped them from working in the area of the bog last
week and was to meet with Mr. King and the Village staff on Wednesday to discuss. The Village secretary
called a few minutes ago to cancel due to a family emergency. I have contact info for Matt King in my office
and I will send it to you tomorrow. More after I meet with the village.
Thanks

See the attached copy of the first couple of pages of the SW permit (issued November 5.2008)
and an overview of -the approved plan (with the wetlands outlined in blue). The new owner
needs to transfer the permit and needs to follow the approved SW plan. We have a copy here in
ARO, in case he does not have a copy. This was permitted as a post construction SW permit, so
I am trying to run down the history on that. (Natalie, you may can provide some historical

Subject: King Creek Bog Location/Landowner Map and Braewood Development Plan'as
requested for Permit SW-1080802
Hi Laura,
Thanks for looking into permit for this so we might review the stormwater plans for this
development. King Creek Bog is owned by three entities. Matt King/Morgan Family
Investments recently purchased Braewood failed development at auction (once owned by
Swing/then TD Bank foreclosed). The maps attached focus on the Potts property (they own a
significant portion of the bog), where we' are funding a bog restoration/management project. We
have also funded management for invasive, exotic plants on Rick Merrill's property (also part
owner of King Creek bog) in past years.
We are very concerned about storm waterlcontaminants entering bog, changing the chemistry of
site (bogs are nutrient poor), and impacting negatively rare species. This bog contains occupied
habitat significant for two rare plants that are critically endangered and protected under the
Endangered Species Act. If you have an approved plan that we can review, it will help us to
determine the type of impacts we might expect from this development, and we hope in the future
to work with the developer and future landowners to reduce these impacts to King Creek bog.
Note that the FWS restoration program I oversee focuses on mountain bog management and
conservation, and may offer incentives to landowners (technical assistance and funding) to
restore and manage mountain bogs, and as well as treat stormwater through LID practices, on
their property.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in'a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
0 does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum" pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
