COUNTY OF FORSYTH
IN THE MATTER OF ASSESSMENT )
OF CIVIL PENALTIES AGAINST: )
Robitthood Court Apartment Homes, LLC )
DWQ Case Number PC-201 1-0041
REQUEST FOR ORAL PRESENTATION
I hereby request to make an oral presentation before the Environmental Management Commission's Committee On Civil Penalty
Remissions in the matter of the case noted above. In making this request, I assert that I understand all of the following statements:
This request will be reviewed by the Chairman of the Environmental Management Commission and may be either granted or
denied
• Making a presentation will require the presence of myself and/or my representative during a Committee meeting held in
Raleigh, North Carolina.
• My presentation will be limited to discussion of issues and information submitted in my original remission request, and
because no factual issues are in dispute, my presentation will be limited to five (5) minutes in length.
The North Carolina State Bar's Authorized Practice of Law Committee has ruled that the appearance in a representative capacity at
quasi-judicial hearings or proceedings is limited to lawyers who are active members of the bar. Proceedings before the Committee on
Remissions are quasi-judicial, You should consider how you intend to present your case to the Committee in light of the State Bar's
opinion and whether anyone will be speaking in a representative capacity for you or a business or governmental entity. If you or your
representative would like to speak before the Committee, you must complete and return this form within thirty (30) days of receipt of
this letter.
Depending on your status as an individual, corporation, partnership or municipality, the State Bar's Opinion affects how you may
proceed with your oral presentation. See www.ncbar.com/ethics, Authorized Practice Advisory Opinion 2006-1 and 2007 Formal
Ethics Opinion 3.
• If you are an individual or business owner and are granted an opportunity to make an oral presentation before the Committee,
then you do not need legal representation before the Committee; however, if you intend on having another individual speak
on your behalf regarding the factual situations, such as an expert, engineer or consultant, then you must also be present at the
meeting in order to avoid violating the State Bar's Opinion on the unauthorized practice of law.
• If you are a corporation, partnership or municipality and are granted an opportunity to make an oral presentation before the
Committee, then your representative must consider the recent State Bar's Opinion and could be considered practicing law
without a license if he or she is not a licensed attorney. Presentation of facts by non -lawyers is permissible.
If you choose to request an oral presentation, please make sure that signatures on the previously submitted Remission Request form
and this Oral Presentation Request form are: I) for individuals and business owners, your own signature and 2) for corporations,
partnerships and municipalities, signed by individuals who would not violate the State Bar's Opinion on the unauthorized practice of
law.
Also, be advised that the Committee on Civil Penalty Remissions may choose not to proceed with hearing your case if the
Committee is informed that a violation of the State Bar occurs.

rev 1.0 - 8.31.09
f

Summary of Robinhood Court Apartment Homes, LLC Remission Request:
• Failure to submit designer's certification for Bioretention Cell 94 resulted from the engineer's (Wescott.
Small & Associates PLLC) failure to complete and submit the certification. Bioretention Cell #4 was
certified on 8/8/1 1.
• Bioretention Cell #4 not being constructed as per the approved plan was an oversight and not noticed by
the Robinhood representative. the designer, or the onsite contractor. Robinhood acted in good faith to
bring this site into compliance.
• Robinhood addressed many of the items aver the DWQ site visit but before the DWQ 5/31/11 NOV
was issued as detailed in the 7/6/1 1 response from the engineer.
• The breach of Infiltration Trench 42 was inadvertent and possibly due to faulty construction or other
unforeseen factors. The engineer met with DWQ onsite to discuss how to repair the measure.
• Robinhood has incurred great expenses to correct the items listed in the NOV including nearly S 10,000
in engineering fees. Also, Robinhood has recently received DWQ approval to convert Bioretention
Cell # 1 to a Wet pond which may cost $40,000 to construct.
• Robinhood says that having to pay the full assessment will be a financial burden with addition to the
costs of achieving compliance. Robinhood may have to find financing from other sources which may
be very difficult to do in the current fiscal environment.
Enforcement History
On March 3 1, 2010 and August 23, 2010 (resent on September 20, 2010), DWQ issued Notices of Violations to
Robinhood Court Apartment Homes LLC. On November 19, 2010, DWQ assessed a civil penalty, case number
PC-2010-1 IS, against Robinhood Court Apartment Homes LLC for different stormwater and sedimentation
violations on the same Robinhood Court Apartment Homes site.

Case Number: PC-2011-0041 Region: Winston-Salem County: Forsyth
Assessed Entity: Robinhood Court Apartment Homes, LLC Permit: SW4090401 MOD
❑ (a) Whether one or more of the civil penalty assessment factors were wrongly applied to the detriment
of the petitioner:
® (b) Whether the violator promptly abated continuing environmental damage resulting from the
violation:
Robinhood Court Apartment Homes, LLC (Robinhood) addressed many of the items after the DWQ site visit but
before the DWQ 5/31/1 1 NOV was issued as detailed in the 7/6/1 1 response from the engineer.
Robinhood Court Apartment Homes LLC has historically responded quickly to violations and problems noted
at the site. However maintenance and construction problems continue to he found at the site, and are not
addressed until tnoted by a DWQ inspection. The Storm water Permit requires that routine inspections occur
and all operation and maintenance problems be addressers immediately.
Tire site is currently in compliance, however they have been provided until Decemher 31, 2011 to provide
permanent stable vegetation along the .side slopes of Bioretention Cell #2 and #3 ► nd to provide permanent
slahle vegetation of file slopes above the Infthration Basins #1 and #2. lit addition they are required to
provide an Engineer's Certification for the approved BMP recently issued in a Modification dated September
20, 2011 within 60 days of issuance of lire Modification
® (c) Whether the violation was inadvertent or a result of an accident:
The failure to submit the designer's certification resulted from the engineer's failure to complete and submit the
certification. Most of the other permit violations were due to oversight and not noticed by the Robinhood
representative, the designer, or the onsite contractor. The breach of Infiltration Trench #2 was inadvertent and
possibly due to faulty construction or other unforeseen factors. Robinhood Court Apartment Homes, LLC acted in
good faith to bring this site into compliance.
It is the Permittee's responsihility to ensure their consultant, engineer and contractors conduct business in
accordance with the Permit issued to Rohinhood Court Apartment Homes LLC.
❑ (d) Whether the violator had been assessed civil penalties for any previous violations:
® (e) Whether payment of the civil penalty will prevent payment for the remaining necessary remedial
actions:
Robinhood has incurred great expenses to correct the items listed in the NOV including nearly $10,000 in
engineering fees. Also, Robinhood has recently received DWQ approval to convert Bioretention Cell # 1 to a Wet
pond which may cost $40,000 to construct. Robinhood says that having to pay the full assessment will be a
financial burden with addition to the costs of achieving compliance. Robinhood may have to find financing from
other sources which may be very difficult to do in the current fiscal environment.
Tine arpenses noted by Robinhood Court Apartment Homes LLC would not have been necessary if the
stormwater measures had been properly installed, routinely inspected, andproperly maintained. In addition, if
site stabilization had been improved, many of the problems would not have occurred. The Permittee has
requested that the Bioretention Cell #1 be converted to a Wet Pond. Any additional financial burden as a
result of this request was a business decision made by Rohinhood. The Stormwater Plan was approved in
2009. All e.Ypenses regarding the installation, inspection and maintenance of these measures were known and
should have been considered before construction began.

Dear Ms. Higgins:

DENR- WATER QUALITY
kkftj AND STCAWATERW WGH
Please accept this letter and the attached "Waiver of Right to an Administrative Hearing and Stipulation of
Facts" and "Justification for Remission Request" forms with regard to the referenced case. We recognize that the
remission request forecloses the option of an administrative hearing. We acknowledge that the facts stipulated
are essentially accurate and correct, but we ask that you give consideration -to the circumstances associated with
those events and the economic hardship and impact that the penalty will have on Robinhood Court Apartment
Homes, LLC, in particular, to complete the outstanding work to convert the TSi (Biocell #4) to a wet pond.
We respectfully request mitigation of the civil penalties imposed based on the following facts:
1. the failure of Robinhood Court Apartment Homes, LLC to provide the designers certification for
Bioretention Cell #4 resulted from, in part the designer's failure to complete and timely submit the
certification. Robinhood Court Apartment Homes, LLC had engaged the site contractor, Rick Mabe
Grading to construct Bioretention Cell #4. Westcott, Small and Associates as the site designer was
engaged to inspect and approve the construction of this Bioretention Cell as well as the other storm
water management systems on site. During the early part of November, 2010 the
Bioretention Cell was completed. Prior to the onset of construction, Westcott, Small and Associates was
consulted to obtain approval to permit a variance in the location of the Bioretention Cell because of the
inability to situate the Cell as shown on the plans.
We were advised by Westcott, Small and Associates that a minor shift in the location of the Cell would
be OK provided that the overall characteristics of the Bioretention Cell were in accord with the approved
design. Based on this assurance we gave authorization to the site contractor to make a relatively small
shift in the location because topographic and space limitations would not have permitted construction of
the Bioretention Cell as shown on the plans.
As part of the construction process, we had Westcott, Small inspect the construction of the Cell and
in particular to witness the installation of the underground drainage system. While representatives from
Westcott, Small and Associates were on site at several occasions during the construction of this Cell,
1

their firm experienced staff changes during this time which in our opinion, resulted in a slip-up in the
completion of the paperwork, but more importantly in not noting a construction error by the site
contractor. Specifically, with regard to the timeliness of the certification of this Bioretention Cell,
construction was completed in November 2010 and as set forth in ECS Carolinas, LLP letter of November
19, 2010, the soil mixture of the Bioretention Cell was analyzed and approved. A copy of this letter
was forwarded to Westcott, Small and Associates as what was believed to be the final information
required by Westcott for their certification. Unfortunately, for whatever reason Westcott, Small did not
receive or act upon this notice and no certification was prepared or submitted to DWQ.
The apparent discrepancy in the detail of construction of Bioretention Cell #4 was not noted by our
representative, the design engineer, the general contractor of the project (Windsor Contracting), or the
site contractor. It was not until the May 19, 2011 DWQ staff inspection that anyone realized that the
Bioretention Cell was missing the forebay. As noted in Mr. Westcott's letter of July 6, 2011 Ms. Sue
Homewood and Mr. Westcott agreed to use the trench drain as the Torbay. Mr. Westcott
accordingly modified the plans to reflect this change and the modified plans were approved by DENR.
Accordingly, no changes to the Bioretention Cell were required and the Cell as constructed was
approved. Mr. Westcott certified this Bioretention Cell on August 8, 2011 after obtaining a final set of
approved plans by DNER .
We respectfully are asking for mitigation of the civil penalty imposed by DWQ for 1) failing to install the
Bioretention Cell prior to the operation of this facility and 2) failure to install the Bioretention Cell in
accordance with the permit approved plans. We have acted in good faith to complete the facility
timely and the failure to have the facility certified resulted in part from others failure as well. We trust
that you will give consideration to the fact that the final approved drawings of the Bioretention Cell did
not require any modification to the Bioretention Cell itself. The Bioretention Cell was completed before
the November 19, 2010 soil assessment by ECS Carolinas, LLP. Accordingly, the Bioretention Cell was
technically functioning in November 2010. Even the french drain around the tennis court that Ms.
Homewood questioned the presence of was installed at the time that the Bioretention Cell was
constructed, but was not noticed on DWQ May 29, 2011 visit.
2. We believe that the record will show that Robinhood Court Apartment Homes, LLC responded quickly to
address those items set forth in the May 31, 2011 NOV. In fact, prior to the receipt of the NOV on June
1, 2011, one of Robinhood Court Apartment Homes, LLC staff members learned of DWQ site visit and
their concerns. He alerted Mr. Wayne Freeman, Director of Maintenance at BSC Holdings, to make him
aware of the issues noted by DWQ staff. Once these issues were called to our attention we engaged
Westcott, Small and Associates, the site designer to conduct a site assessment and to advise us on a
course of action to address the concerns correctly and appropriately. After a field inspection Mr.
Westcott advised that we address all of the situations except the variance in construction of Bioretention
Cell #4 and the breach of Infiltration Trench #2. Mr. Westcott wanted to meet with Ms. Sue Homewood
to review these situations firsthand and agree on a course of action.
We believe that when you read Mr. Westcott's letter of July 6, 2011 to Ms. Homewood that it is clear
that we responded very quickly to address each and everyone of the concerns set out in the NOV. Some
of the issues set forth in the NOV actually were not issues as pointed out by Mr. Westcott, such as the
length of the vegetative filter strip at Bioretention Cell #4, the under drains extending into the forebay at
Bioretention Cell #3, the elevations in Bioretention Cell #2 not being high enough, and Infiltration Trench
#3 not draining properly. Irregardless, Robinhood Court Apartment Homes took these issues seriously
and at considerable expense addressed all of the issues set out in the NOV without any hesitation.
Once Mr. Westcott and Ms. Homewood came to agreement on the course of action for the repair of the
breach of infiltration Trench #2 and the required revision of the drawings for Bioretention Cell #4, work
was commenced and proceeded diligently. I do want to point out that with Mr. Westcott's concurrence
we suggested what was considered a permanent fix to the breach area of the infiltration trench, despite
the substantial cost involved in taking such an approach.
E

As of this date we believe that each and every one of the issues set forth in the NOV have been addressed
with the exception of converting the sediment basin (location of Bioretention Cell #1) into a wet pond.
We have just received an approved set of plans (dated September 20, 2011) and have sent the plans to
several site contractors for pricing. It is our intent to start work on the wet pond shortly.
3. We believe that the breach of Infiltration Trench #2 was inadvertent. First of all, we recognize that
Robinhood Court Apartment Homes, LLC is the record owner of this complex and as such is ultimately
responsible. However, in fairness, we want to point out that we, like everyone else, rely upon others to
undertake and complete in a professional manner those tasks that we have entrusted them to perform.
Accordingly, we had entrusted our design engineer to design the embankment of this infiltration trench to
withstand anticipated rain events of exceptional magnitude, we entrusted the site contractor to construct
the infiltration trench in accord with the designer's details, we entrusted the general contractor who had
the responsibility to oversee all construction/site development on the site, and we certainly entrusted the
design engineer when he certified the construction of this infiltration trench in April 2009. Unfortunately,
something went wrong and a small portion of the trench gave way leading to a sedimentation impact to
the unnamed tributary to Muddy Creek. We recognize and agree that our staff may have failed to detect
any telltale signs of a potential failure or erosion in the trench at the area of the breach. The fact that
other areas of the trench did not exhibit any telltale signs of possible failure or eroding would suggest that
we may have had faulty construction in the breached area or that the design did not fully take into
account unforeseen factors that could have exerted additional stress in the location that ultimately failed.
Since the NOV we had, with our designer engineers assistance and with concurrence of DWQ, built an
embankment that should certainly preclude failure in the future. Furthermore, we have "passed on the
heat" to our maintenance staff to do a better job of inspecting and taking preventive measures to
avoid situations in the future and to be more religious in their inspection of all of the storm water
management features.
4. As setforth in Mr. Westcott's letter of July 6, 2011,- and as further attested to by his certification of
Bioretention Cell #4, and undoubtedly by Ms. Homewood subsequent visits to the site, Robinhood Court
Apartment Homes, LLC has undertaken at great expense all actions to address those items enumerated in
the NOV. Such expenses included nearly $10,000 in engineering fees to Westcott, Small and Associates
and a similar expenditure to address those items to the satisfaction of DWQ. We have recently
(September 20, 2011) obtained approval by DENR to convert the TST to a wet pond. We have forwarded
copies of the plans to various site contractors to obtain a bid to undertake the work. While not all
contractors have yet responded, the bid amounts have come in far above our expectations. In fact, the
latest bid we received is approximately $40,000 which does not include planting of the shelf area or
seeding of the pond. Regardless of where the final costs comes in this additional expenditure will create
financial hardship on Robinhood Court Apartment Homes, Robinhood Court Apartment Homes does not
have any funding available and would have to procure financing from other sources to complete this
work. We recognize that this work must be done and done timely in accord with the representation made
by Mr. Westcott to DWQ in his letter of July 6, 2011. Having to find an additional $16,377.61 to satisfy
the civil assessment imposed by DWQ will add to the financial burden on Robinhood Court Apartment
Homes which is now just fulfilling its financial obligations to its lenders as well as to the timely payment
all of the property's operating costs. Frankly, we do not know how we can handle both obligations at this
time unless we obtain financing from other sources which is difficult to do in this fiscal environment.
Accordingly, we request remission of the civil penalty so that we may endeavor to pay the mitigated
amount and be able to timely undertake the work required to convert the TST to a wet pond.
9

Accordingly, we respectfully ask that you take all of these factors into consideration. We recognize our
responsibility but ask that you give substantial consideration to everything that we have willingly done to address
the situation in a timely and responsible manner.
Respectfully submitted

Dear Mr. Siegal:
ECS Carolinas, LLP (ECS) is pleased to provide you with our Report of Soil Mixture
Assessment for the referenced property. Our services were provided in general accordance with
ECS Proposal No. 09-17027-P.
PROJECT OVERVIE
ECS has conducted a soil mixture assessment of the bio-retention cell at the Robinhood Court
Apartments located on Robinhood Road in Winston Salem, North Carolina. The bio-retention
cell was installed adjacent to the tennis courts along Robinhood Road. The purpose was to
determine if the soil mixture is consistent with the engineer's recommendation.
SCOPE OF WORK
On November 19, 2010, ECS conducted an assessment of the soli mixture of the bio-retention
cell installed adjacent to the tennis courts at the Robinhood Court Apartments located on
Robinhood Road in Winston Salem, North Carolina. This assessment was conducted with a
hand auger in accordance with current soil science practices and technology and the soil criteria
found in the USDA Field Book for Describing and Sampling Soils, Version 2.0. A control sample
provided by the client was tested by ECS.
REPORT OF FINDINGS
Two soil borings were drilled to 20 to 30 inches below ground surface (bgs). The texture of the
soil mixture is sandy loam. The texture and material appear to be consistent with the control
sample. Moisture content was consistent throughout the boring. Based on the soil mixture
properties and characteristics, the permeability ranges from 0.6 to 2.0 inches per hour.

Re: Robinhood Court Apartment Homes NOV
Dear Ms. Homewood:
Z'stcco ; Small
Associates, PLLC
I am writing on behalf of my client BCS Holdings, the developer of the above referenced project. First,
I would like to say thank you to you and Robert Patterson for meeting with us on site to examine the
progress to date and discuss how to move forward. Your comments and our responses as well as what
was agreed to on site are as follows.
1. Condition 116 states the fallowing: "Upon completion of construction, prior to issuance of a Certificate of
Occupancy, and prior to operation of this permitted facility, a certification must be received from an
appropriate designer for the system installed certifying that the facility has been installed in accordance with
this permit, the approved plans and specifications, and other supporting documentation. "
• A file review has indicated that an engineer's certification has not been received for Bioretention Cell #1
and Bioretention Cell #4. The Division is aware that Bioretention Cell #1 could not be constructed until
it was no longer necessary as a sediment basin. Discussions with the Forsyth County inspections office
has indicated that the project has been determined to be stable and therefore conversion to a permanent
stormwater control structure must occur immediately. The owner has made the agreed to changes to
Biocell #4. Our office will provide you and Robert with an As -Built plan and set of calculations by July
15th. Once these are approved I will provide a certification on this bocell. We are in the process of
working on the permitting to turn Biocell #1 into a wet pond. I expect to have the paperwork for this to
Robert early next week. I have the Owners assurances that as soon as we can get Robert's approval that
construction will begin. I expect the construction to take no more than 60 days. I will be certifying this
BMP as well.
2. Condition 11.6 of Permit No. SW4090401 states the following: "the facilities shall be constructed as shown on
the approved plans. " The following violations were noted during the site inspection:
• Bioretention Cell #4 was not located as shown on the approved plans. As indicated above we will turn in
an As -Built set of plans and calculations.
• The vegetated filter strip at Bioretention Cell 44 does not appear to be the approved length. I have
measured this and the fitter strip is in compliance with the size on the approved plan.
• There was no evidence of a trench drain around the tennis court as shown in the approved plans to direct
runoff to Bioretention Cell #4. This trench drain has been installed and the Owner and the retaining wall
has been turned back as we discussed on site.
4015 Meeting Way, Suite 105 • High Point, North Carolina 27265 • phone: [phone] o fax.• 336-812-8075

• Bioretention Cell #4 was missing the forebay as indicated in the approved plans. As discussed on site we
will use the trench drain as the forebay and this will be reflected on the As -Built plans.
• The roof drains behind building 7 do not drain to the infiltration trench as indicated on the approved
plans. As you saw during our site visit this has already been accomplished.
• The outlet structure (weir) of Bioretention Cell #3 appears to be at a similar elevation as the planting
elevation and therefore not providing the approved storage volume/ponding depth. This weir has been
adjusted to provide the required ponding. This was completed prior to the site visit.
• The vegetated filter strip at Bioretention Cell #3 does not appear to be the approved length. The Owner
has filled in the area near the creek as we agreed to during the site visit. He has also extended the length
of the filter strip by removing some of the gravel at the level spreader and seeding that area as we
discussed during your site visit,
• The underdrain appears extend into the forebay of Bioretention Cell #3, which may allow the runoff to
bypass the filter media. As we discussed during the site visit, the underdrain pipes in this are do not have
holes in them.
• The vegetation present in Bioretention Cell #2 and #3 does not match the approved planting plans. The
owner has overseeded these areas and.will continue to overseed until grass is better established. We have
some concerns about how well the seeding will germinate given the season. This fall we should be able
to address this completely but the Owner will continue to overseed until this is addressed.
• Observation wells were notpresent in all locations within Infiltration Trench 91 or Infiltration Trench #2.
The owner had placed most of these observation wells prior to the site visit. The remainder of them have
been put in place and are functioning. I have observed them, before a rain, after a rain (drawdown) and
after drawdown.
3. Condition R 3 of Permit No. SW4090401 states the following: "The permittee shall at all time provide the
operation and maintenance necessary to assure the permitted stormwater system functions at optimum
efficiency. The following maintenance violations were noted during the site inspection:
• There are areas within Bioretention Cell #2 that do not have sufficient vegetation. The owner has
overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.
• There are areas of built up debris within Bioretention Cell #2, particularly at the outlet area. Prior to the
site visit, the debris had been removed.
• It appears that the elevations in Bioretention Cell #2 are causing the cell to overflow across a low point
in the perimeter berm rather than via the designed outlet. I have shot the elevations in this area and the
berm at this point is high enough not to overtop in the design storm.
• Perimeter slopes of Bioretention Cell #2 are insufficiently vegetated. The owner has overseeded these
areas and will continue to overseed until grass is better established. We have some concerns about how
well the seeding will germinate given the season. This fall we should be able to address this completely
but the Owner will continue to overseed until this is addressed.
• The forebay of Bioretention Cell #2 is clogged with sediment and vegetation. Prior to the site visit, the
sediment and vegetation had been removed and the forebay had been reconstructed.
• Infiltration Trench #3 has received excessive sedimentation from erosion of the inlet swale. The sediment
has been removed and new stone placed in the infiltration trench.
• Infiltration Trench #3 is not properly draining. I have observed all of the biocells and infiltration
trenches both 24 and 48 hours after a rain event and all of them are infiltrating as designed.
• The vegetated filter strip below Infiltration Trench #3 is being bypassed by flow on both sides. As you
saw during the site visit, the owner has constructed a berm on both sides of the filter to keep the water on
the filter. This seems to have worked based on my recent site visits after rain events.

• Portions of Infiltration Trench #1 and Infiltration 42 have been impacted by sediment which may be
clogging the media. The owner has cleaned off the fabric covering the trenches.
• A portion of Infiltration Trench 42 has been breached and has been inappropriately repaired with riprap.
The trench is no longer providing the approved storage volume. As discussed on site, the owner has
installed a retaining wall and repairing the breach.
• Slopes up -gradient oflnfltration Trench #1 and Infiltration #2 are insufficiently vegetated. The owner
has overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.
Stream Standard Violations:
• Specifically, 15A NCAC 2B.0216 which references 15A NCAC 2B .0211 (3)69 which states: Oils;
deleterious substances; colored or other wastes: only such amounts as shall not render the waters
injurious to public health, secondary recreation or to aquatic life and wildlife or adversely affect the
palatability offish, aesthetic quality or impair the waters for any designated uses; for the purpose of
implementing this Rule, oils, deleterious substances, colored or other wastes shall include but not be
limited to substances that cause a film or sheen upon or discoloration of the surface of the water or
adjoining shorelines pursuant to 40 CFR 110.4(a)-(b) which are hereby incorporated by reference
including any subsequent amendments and addition. The site investigation confirmed that as a result of
the construction activities and subsequent failure of slopes behind buildings 7, 8 and 9 and below
Infiltration Trench #2 sediment has been deposited in the stream. Approximately 200 feet of stream
impacts to an unnamed tributary to Muddy Creek occurred as a result of the land disturbing activities at

Summary of Robinhood Court Apartment Homes, LLC Remission Request:
• Failure to submit designer's certification for Bioretention Cell #4 resulted from the engineer's (Wescot
Small & Associates PLLC) failure to complete and submit the certification. Bioretention Cell #4 was
certified on 8/8/11.
• Bioretention Cell #4 not being constructed as per the approved plan was an oversight and not noticed b
the Robinhood representative, the designer, or the onsite contractor. Robinhood acted in good faith to
bring this site into compliance.
• Robinhood addressed many of the items after the DWQ site visit but before the DWQ 5/3 1/11 NOV
was issued as detailed in the 7/611 1 response from the engineer.
• The breach of Infiltration Trench #2 was inadvertent and possibly due to faulty construction or other
unforeseen factors. The engineer met with DWQ onsite to discuss how to repair the measure.
• Robinhood has incurred great expenses to correct the items listed in the NOV including nearly $10,000
in engineering fees. Also, Robinhood has recently received DWQ approval to convert Bioretention
Cell # l to a Wet pond which may cost $40,000 to construct.
• Robinhood says that having to pay the full assessment will be a financial burden with addition to the
costs of achieving compliance. Robinhood may have to find financing from other sources which may
be very difficult to do in the current fiscal environment.
Enforcement History
On March 31, 2010 and August 23, 2010 (resent on September 20, 2010), DWQ issued Notices of Violations to

Dear Ms. Higgins:
E PC�RdIN P
OCT 1 4 2011
DENR - WATER QUALITY
tN TLMD6 AND 6TORNIVATER BRA "
Please accept this letter and the attached "Waiver of Right to an Administrative Hearing and Stipulation of
Facts" and "Justification for Remission Request" forms with regard to the referenced case. We recognize that the
remission request forecloses the option of an administrative hearing. We acknowledge that the facts stipulated
are essentially accurate and correct, but we ask that you give consideration to the circumstances associated with
those events and the economic hardship and impact that the penalty will have on Robinhood Court Apartment
Homes, LLC, in particular, to complete the outstanding work to convert the TST (Biocell #4) to a wet pond.
We respectfully request mitigation of the civil penalties imposed based on the following facts:
The failure of Robinhood Court Apartment Homes, LLC to provide the designers certification for
Bioretention Cell #4 resulted from, in art the designer's failure to complete and timely submit the
certification. Robinhood Court Apartment Homes, LLC had engaged the site contractor, Rick Mabe
Grading to construct Bioretention Cell 44. Westcott, Small and Associates as the site designer was
engaged to inspect and approve the construction of this Bioretention Cell as well as the other storm
water management systems on site. During the early part of November, 2010 the
Bioretention Cell was completed. Prior to the onset of construction, Westcott, Small and Associates was
consulted to obtain approval to permit a variance in the location of the Bioretention Cell because of the
inability to situate the Cell as shown on the plans.
We were advised by Westcott, Small and Associates that a minor shift in the location of the Cell would
be OK provided that the overall characteristics of the Bioretention Cell were in accord with the approved
design. Based on this assurance we gave authorization to the site contractor to make a relatively small
shift in the location because topographic and space limitations would not have permitted construction of
the Bioretention Cell as shown on the plans.
As part of the construction process, we had Westcott, Small inspect the construction of the Cell and
in particular to witness the installation of the underground drainage system. While representatives from
Westcott, Small and Associates were on sit occasions Burin the construction of this Cell,

their firm experienced staff changes during this time which in our opinion,_re rn a 51ip--up io the
completion of the paperwork, but more importantly in not noting a construction -error by --the site
co c or. Sp-- ica y, with regard to the timeliness of the certification of this Bioretention Cell,
construction was completed in November 2010 and as set forth in ECS Carolinas, LLP letter of November
19, 2010, the soil mixture of the Bioretention Cell was analyzed and approved. A copy of this letter
was forwarded to Westcott, Small and Associates as what was believed to be the final information
required by Westcott for their certification. Unfortunately, for whatever reason Westcott, Small did not
receive or act upon this notice and no certification was prepared or submitted to DWQ.
The apparent discrepancy in the detail of construction of Bioretention Cell #4 was not noted by our
representative, the design engineer, the general contractor of the project (Windsor Contracting), or the
site contractor. it was not until the May 19, 2011 DWQ staff inspection that anyone realized that the
Bioretention Cell was missing the forebay. As noted in Mr. Westcott's letter of July 6, 2011 Ms. Sue
Homewood and Mr. Westcott agreed to use the trench drain as the forbay. Mr. Westcott
accordingly modified the plans to reflect this change and the modified plans were approved by DENR.
Accordingly, no changes to the Bloretention Cell were required and the Cell as constructed was
approved. Mr. Westcott certified this Bioretention Cell on August 8, 2011 after obtaining a final set of
approved plans by DNER .
We respectfully are asking for mitigation of the civil penalty imposed by DWQ for 1) failing to install the
Bioretention Cell prior to the operation of this facility and 2) failure to install the Bioretention Cell in
accordance with the permit approved plans. We have acted in good faith to complete the facility
timely and the failure to have the facility certified resulted in part from others failure as well. We trust
that you will give consideration to the fact that the final approved drawings of the Bioretention Cell did
not require any modification to the Bioretention Cell itself. The Bioretention Cell was completed before
the November 19, 2010 soil assessment by ECS Carolinas, LLP. Accordingly, the Bioretention Cell was
technically functioning in November 2010. Even the french drain around the tennis court that Ms.
Homes ewoodthe presence. of was installed at the time that the Bioretention Cell was
constructed, but was not noticed on DWQ May 29, 2011 visit.
2. We believe that the record will show that Robinhood Court Apartment Homes, LLC responded quickly to
address those items set forth in the May 31, 2011 NOV. In fact, prior to the receipt of the NOV on June
1, 2011, one of Robinhood Court Apartment Homes, LLC staff members learned of DWQ site visit and
their concerns. He alerted Mr. Wayne Freeman, Director of Maintenance at BSC Holdings, to make him
aware of the issues noted by DWQ staff. Once these issues were called to our attention we engaged
Westcott, Small and Associates, the site designer to conduct a site assessment and to advise us on a
course of action to address the concerns correctly and appropriately. After a field inspection Mr,
Westcott advised that we address all of the situations except the variance in construction of Bioretention
Cell #4 and the breach of Infiltration Trench #2. Mr. Westcott wanted to meet with Ms. Sue Homewood
to review these situations firsthand and agree on a course of action,
We believe that when you read Mr. Westcott's letter of July 6, 2011 to Ms. Homewood that it is clear
that we responded very quickly to address each and everyone of the concerns set out in the NOV. Some
of the issues set forth in the NOV actually were not issues as pointed out by Mr. Westcott, such as the
nth of the vegetative filter stri at BioretegtiQU Cell #4 tP uncler-a�rains extending into the forebay at
Bioretention Cell #3, the elevations_ in Bioretention_ Cell #2 not being high enough, and Infiltration Trench
---#3 nordrainm roperly, Irregardless, Robinhood Court Apartment Homes took these issues seriously
an at considerable expense addressed all of the issues set out in the NOV without any hesitation.
Once Mr. Westcott and Ms. Homewood came to agreement on the course of action for the repair of the
breach of infiltration Trench #2 and the required revision of the drawings for Bioretention Cell #4, work
was commenced and proceeded diligently. I do want to point out that with Mr. Westcott's concurrence
we suggested what was considered a permanent fix to the breach area of the infiltration trench, despite
the substantial cost involved in taking such an approach.

As of this date we believe that each and every one of the issues set forth in the NOV have been addressed
with�vxception-of-converting-th,- in
We have just received an approved set of plans (dated 5epttwbRr2Q_z011)-and_have-4entthe-plans to
-sepriprictrig tit-isourintentto-startwork-on-the -wet -pond-shorNy-
3, We believe that the breach of Infiltration Trench #2 was inadvertent. First of all, we recognize that
Robinhood Court Apartment Homes, LLC is the record owner of this complex and as such is ultimately
responsible. However, in fairness, we want to point out that we, like everyone else, rely upon others to
undertake and complete in a professional manner those tasks that we have entrusted them to perform.
Accordingly, we had entrusted our design engineer to design the embankment of this infiltration trench to
withstand anticipated rain events of exceptional magnitude, we entrusted the site contractor to construct
the infiltration trench in accord with the designer's details, we entrusted the general contractor who had
the responsibility to oversee all construction/site development on the site, and we certainly entrusted the
design engineer when he certified the construction of this infiltration trench in April 2009. Unfortunately,
something went wrong and a small portion of the trench gave way leading to a sedimentation impact to
the unnamed tributary to Muddy Creek. We recognize and agree that our staff may have failed to detect
any telltale signs of a potential failure or erosion in the trench at the area of the breach. The fact that
other areas of the trench did not exhibit any telltale signs of possible failure or eroding would gyM t that
we ached area ar that the
account unforeseen factors that could have exerted additional stress in the location that ultimately failed.
Since the NOV we had, with our designer engineers assistance and with concurrence of DWQ, built an
embankment that should certainly preclude failure in the future. Furthermore, we have "passed on the
heat" to our maintenance staff to do a better job of inspecting and taking preventive measures to
avoid situations in the future and to be more religious in their inspection of all of the storm water
management features.
As setforth in Mr. Westcott's letter of July 6, 2011, and as further attested to by his certification of
Bioretention Cell #4, and undoubtedly by Ms. Homewood subsequent,visits to the site, Robinhood Court
Apartment Homes, LLC has undertaken at great expense all actions to address those items enumerated in
the NOV. Such ex enses included nearly $10,000 in engineering fees to Westcott, Small and Associates
and a similar expenditure to address those items o e sa is ac ion of DW a have recently
em er 0, 20 11j obtained approval by DENR to convert the TST to a wet pond. We have forwarded
copies of the plans to various site contractors to obtain a bid to undertake the work. While not all
contractors have yet responded, the bid amounts have come in far above our expectations. In fact, the
latest bid we received 4; approximately $40,000 which does not include planting of the shelf area or
seeding of the pond. Regar less of where the final costs comes in this additional expenditure will create
financial hardship on Robinhood Court Apartment Homes. Robinhood Court Apartment Homes does not
have any funding available and would have to procure financing from other sources to complete this
work. We recognize that this work must be done and done timely in accord with the representation made
by Mr. Westcott to DWQ in his letter of July 6, 2011. Having to find an additional $16,377.61 tisfy
the civil assessment imposed by DW o_the-fiaa Robin rt A artment
Homes which is now just fulfilling its financial obligations to its lenders as well as to the timely payment
all of the property's operating costs. Frankly, we do not know how we can handle both obligations at this
time unless we obtain financing from other sources which is difficult to do in this fiscal environment.
Accordingly, we request remission of the civil penalty so that we may endeavor to pay the mitigated
amount and be able to timely undertake the work required to convert the TST to a wet pond.

Accordingly, we respectfully ask that you take all of these factors into consideration. We recognize our
responsibility but ask that you give substantial consideration to everything that we have willingly done to address
the situation in a timely and responsible manner.

ECS Carolinas, LLP (ECS) Is pleased to provide you with our Report of Soil Mixture
Assessment for the referenced property. Our services were provided in general accordance with
ECS Proposal No. 09-17027-P.
PROJECT V RVIEW
ECS has conducted a soil mixture assessment of the bio-retention cell at the Robinhood Court
Apartments located on Robinhood Road in Winston Salem, North Carolina. The bio-retention
cell was installed adjacent to the tennis courts along Robinhood Road. The purpose was to
determine If the soil mixture is consistent with the engineer's recommendation.
OF WORK
On November 19, 2010, ECS conducted an assessment of the soil mixture of the bio-retention
cell installed adjacent to the tennis courts at the Robinhood Court Apartments located on
Robinhood Road in Winston Salem, North Carolina. This assessment was conducted with a
hand auger in accordance with current soil science practices and technology and the soil criteria
found in the USDA Field Book for Describing and Sampling Soils, Version 2.0, A control sample
provided by the client was tested by ECS.
Two soil borings were drilled to 20 to 30 inches below ground surface (bgs). The texture of the
soil mixture is sandy loam. The texture and material appear to be consistent with the control
sample. Moisture content was consistent throughout. the boring. Based on the soil mixture
properties and characteristics, the permeablilty ranges from 0.6 to 2.0 inches per hour.

Re: Robinhood Court Apartment Homes NOV
Dear Ms. Homewood:
1
,estcott; Small
,associates, PLLC
I am writing on behalf of my client BCS Holdings, the developer of the above referenced project. First,
1 would like to say thank you to you and Robert Patterson for meeting with us on site to examine the
progress to date and discuss how to move forward. Your comments and our responses as well as what
was agreed to on site are as follows.
1. Condition 116 states the following: "Upon completion of construction, prior to issuance of a Certificate of
Occupancy, and prior to operation of this permitted facility, a certification must be received from an
appropriate designer for the system installed certifying that the facility has been installed in accordance with
this permit, the approved plans and specifications, and other supporting documentation. "
• A file review has indicated that an engineer's certification has not been received for Bioretention Cell #1
and Bioretention Cell #4. The Division is aware that Bioretention Cell #1 could not be constructed until
it was no longer necessary as a sediment basin. Discussions with the Forsyth County inspections office
has indicated that the project has been determined to be stable and therefore conversion to a permanent
stormwater control structure must occur immediately. The owner has made the agreed to changes to
Biocell #4. Our office will provide you and Robert with an As -Built plan and set of calculations by July
15th. Once these are approved I will provide a certification on this biocell. We are in the process of
working on the permitting, to turn Biocell #.1 into a wet pond. I expect to have the paperwork for this to
Robert early next week. I have the Owners assurances that as soon as we can get Robert's a2proval that
construction will be in. i expect the construction t Ke no more than 60 days. I ill be certifying this
MP as well.
2. Condition 11.6 of Permit No. SW4090401 states the following: "the facilities shall be constructed as shown on
the approved plans. " The following violations were noted during the site inspection:
• Bioretention Cell #4 was not located as shown on the approved plans. As indicated above we will turn in
an As -Built set of plans and calculations.
• The vegetated filter strip at Bioretention Cell #4 does not appear to be the approved length. I have
measured this and the filter strip is in compliance with the size on the approved plan.
• There was no evidence of a trench drain around the tennis court as shown in the approved plans to direct
runoff to Bioretention Cell 94. This trench drain has been installed and the Owner and the retaining wall
has been turned back as we discussed on site.
4015 Meeting Way, Suite 105 a High Point, North Carolina 27265 • phone:[phone] • fax: [phone]

• Bioretention Cell #4 was missing the forebay as indicated in the approved plans. As discussed on site we
will use the trench drain as the forebay and this will be reflected on the As -Built plans,
• The roof drains behind building 7 do not drain to the infiltration trench as indicated on the approved
plans. As you saw during our site visit this has already been accomplished.
• The outlet structure (weir) of Bioretention Cell #3 appears to be at a similar elevation as the planting
elevation and therefore not providing the approved storage volumelponding depth. This weir has been
adjusted to provide the required ponding. This was completed prior to the site visit.
• The vegetated f lter strip at Bioretention Cell #3 does not appear to be the approved length. The Owner
has filled in the area near the creek as we agreed to during the site visit. He has also extended the length
of the filter strip by removing some of the gravel at the level spreader and seeding that area as we
discussed during your site visit.
• The underdrain appears extend into the forebay of Bioretention Cell #3, which may allow the runoff to
bypass the filter media. As we discussed during the site visit, the underdrain pipes in this are do not have
holes in them.
• The vegetation present in Bioretention Cell #2 and #3 does not match the approved planting plans, The
owner has overseeded these areas and.will continue to overseed until grass is better established. We have
some concerns about how well the seeding will germinate given the season. This fall we should be able
to address this completely but the Owner will continue to overseed until this is addressed.
• Observation wells were not present in all locations within Infiltration Trench 91 or Infiltration Trench 42.
The owner had placed most of these observation wells prior to the site visit. The remainder of them have
been put in place and are functioning. I have observed them, before a rain, after a rain (drawdown) and
after drawdown.
3. Condition 1I.3 of Permit No. SW4090401 states the following: "The permittee shall at all time provide the
operation and maintenance necessary to assure the permitted stormwater system functions at optimum
efficiency. The following maintenance violations were noted during the site inspection:
• There are areas within Bioretention Cell 92 that do not have sufficient vegetation. The owner has
overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will,germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.
• There are areas of built up debris within Bioretention Cell #2, particularly at the outlet area. Prior to the
site visit, the debris had been removed.
• It appears that the elevations in Bioretention Cell 92 are causing the cell to overflow across a low point
in the perimeter berm rather than via the designed outlet. I have shot the elevations in this area and the
berm at this point is high enough not to overtop in the design storm.
• Perimeter slopes of Bioretention Cell #2 are insufficiently vegetated. The owner has overseeded these
areas and will continue to overseed until grass is better established. We have some concerns about how
well the seeding will germinate given the season. This fall we should be able to address this completely
but the Owner will continue to overseed until this is addressed.
• The forebay of Bioretention Cell #2 is clogged with sediment and vegetation. Prior to the site visit, the
sediment and vegetation had been removed and the forebay had been reconstructed.
• Infiltration Trench 43 has received excessive sedimentation from erosion of the inlet swale. The sediment
has been removed and new stone placed in the infiltration trench.
• Infiltration Trench 43 is not properly draining. I have observed all of the biocells and infiltration
trenches both 24 and 48 hours -after a rain event and all of them are infiltrating as designed.
• The vegetated filter strip below Infiltration Trench #3 is being bypassed by flow on both sides. As you
saw during the site visit, the owner has constructed a berm on both sides of the filter to keep the water on
the filter. This seems to have worked based on my recent site visits after rain events.

Portions of Infiltration Trench #1 and Infiltration #2 have been impacted by sediment which may be
clogging the media. The owner has cleaned off the fabric covering the trenches.
A portion of Infiltration Trench lit has been breached and has been inappropriately repaired with riprap.
The trench is no longer providing the approved storage volume. As discussed on site, the owner has
installed a retaining wall and repairing the breach.
Slopes up -gradient oflnfiltration Trench #1 and Infiltration #2 are insufficiently vegetated. The owner -
has overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.

Dee Freeman
Secretary
The Division of Water Quality Central Office received a Stormwater Management Permit Application to
modify the subject project on August 22, 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:
1. Only one copy of sheet C-8 was received. Please submit two copies of any revised plan
sheets.
2. The cross section on C-10-H needs to be revised to show the vegetated shelf with a 10:1
slope.
3. Page 3 of the 0&M Agreement is blank. Please fill-in this information.
4.. The following values on the supplement form appear to be incorrect: sediment clean out
top and bottom elevations, volume provided, and "depth", average depth calculated and
used for calculation option #2.
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 September 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 mail, fax, or email 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.

Lrtal C"C,
The Stormwater Permitting Unit received a request for a plan revision for Stormwater Management
Permit Number SW4090401 on July 22, 2011. The plan revision includes the revised location and
configuration of bioretention cell #4; and does not change the overall bua or the other previously
approved BMPs. It has been determined that a formal permit modification is not required for the
proposed changes. We are forwarding you an approved copy of the revised plan for your files. Please
replace the existing stamped approved plan sheet C-10-G (Bio-Cell Grass #4) with the enclosed
stamped approved plan sheet C-10-G. Section 1.8 of the permit was revised to reflect the changes in
Cell #3.
Please be aware that all terms and conditions of the permit issued on June 24, 2010 remain in full force
and effect. Please also understand that the approval of this revision to the approved plans for the subject
State Stormwater permit is done on a case -by -case basis. Any other changes to this project must be
submitted to and approved through the Division of Water Quality 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 contact Robert Patterson at [phone], or
[e-mail].

• By December 31, 2011, provide permanent stable vegetation on the slopes above Infiltration Basins
#1 and #2. If continued over -seeding does not provide permanent, stable vegetation at a density to
ensure that these basins will be protected from future erosion/sedimentation then the Permittee is
required to take more aggressive measures to stabilize these slopes.
Thank you for your attention to this matter. This Office is still considering sending a Recommendation for
Enforcement to the Director of the Division of Water Quality regarding these issues and any future/continued
violations that may be encountered. Your above -mentioned response to this correspondence will be considered

Re: Robinhood Court Apartment Homes NOV
Dear Ms. Homewood:
,LC
I am writing on behalf of my client BCS Holdings, the developer of the above referenced project. First,
I would like to say thank you to you and Robert Patterson for meeting with us on site to examine the
progress to date and discuss how to move forward. Your comments and our responses as well as what
was agreed to on site are as follows.
1. Condition 116 states the following: "Upon completion of construction, prior to issuance of a Certificate of
Occupancy, and prior to operation of this permitted facility, a certification must be received from an
appropriate designer far the system installed certifying that the facility has been installed in accordance with
this permit, the approved plans and specifications, and other supporting documentation. "
• A file review has indicated that an engineer's certification has not been received for Bioretention Cell 91
and Bioretention Cell 94. The Division is aware that Bioretention Cell 01 could not be constructed until
it was no longer necessary as a sediment basin. Discussions with the Forsyth County inspections office
has indicated that the project has been determined to be stable and therefore conversion to a permanent
stormwater control structure mast occur immediately. The owner has made the agreed to changes to
Biocell #4. Our office will provide you and Robert with an As -Built plan and set of calculations by July
15th. Once these are approved I will provide a certification on this biocell. We are in the process of
working on the permitting to turn Biocell # l into a wet pond. I expect to have the paperwork for this to
Robert early next week. I have the Owners assurances that as soon as we can get Robert's approval that
construction will begin. I expect the construction to take no more than 60 days. I will be certifying this
BMP as well.
2. Condition 11.6 of Permit Mo. SYi'4090401 states the following: "the facilities shall be constructed as shown on
the approved plans." The following violations were noted during the site inspection:
• Bioretention Cell 94 was not located as shown on the approved plans. As indicated above we will turn in
an As -Built set of plans and calculations.
• The vegetated filter strip at Bioretention Cell 94 does not appear to be the approved length. I have
measured this and the filter strip is in compliance with the size on the approved plan.
• There was no evidence of a trench drain around the tennis court as shown in the approved plans to direct
runoff to Bioretention Cell 94. This trench drain has been installed and the Owner and the retaining wail
has been turned back as we discussed on site.
40151vieeting Way, suite.105 4 Higlf Point, North Carolina 27265 • phone: [phone] i fg,).:336-812.8075

• Bioretention Cell 94 was missing the forebay as indicated in the approved plans. As discussed on site we
will use the trench drain as the forebay and this will be reflected on the As -Built plans.
• The roof drains behind building 7 do not drain to the infiltration trench as indicated on the approved
plans. As you saw during our site visit this has already been accomplished.
• The outlet structure (weir) of Bioretention Cell 43 appears to be at a similar elevation as the planting
elevation and therefore not providing the approved storage volume/ponding depth. This weir has been
adjusted to provide the required ponding. This was completed prior to the site visit.
• The vegetated filter strip at Bioretention Cell 43 does not appear to be the approved length. The Owner
has filled in the area near the creek as we agreed to during the site visit. He has also extended the length
of the filter strip by removing some of the gravel at the level spreader and seeding that area as we
discussed during your site visit.
• The underdrain appears extend into the forebay of Bioretention Cell 93, which may allow the runoff to
bypass the filter media. As we discussed during the site visit, the underdrain pipes in this are do not have
holes in them.
• The vegetation present in Bioretention Cell 92 and 93 does not match the approved planting plans. The
owner has overseeded these areas and will continue to overseed until grass is better established. We have
some concerns about how well the seeding will germinate given the season. This fall we should be able
to address this completely but the Owner will continue to overseed until this is addressed.
• Observation wells were not present in all locations within Infiltration Trench 41 or Infiltration Trench 42.
The owner had placed most of these observation wells prior to the site visit. The remainder of them have
been put in place and are functioning. I have observed them, before a rain, after a rain {drawdown} and
after drawdown.
Condition 11.3 of Permit No. SW4090401 states the following: "The permittee shall at all time provide the
operation and maintenance necessary to assure the permitted stormwater system functions at optimum
efficiency. The following maintenance violations were noted during the site inspection:
• There are areas within Bioretention Cell 92 that do not have sufficient vegetation. The owner has
overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.
• There are areas of built up debris within Bioretention Cell 42, particularly at the outlet area. Prior to the
site visit, the debris had been removed.
• It appears that the elevations in Bioretention Cell 92 are causing the cell to overflow across a low point
in the perimeter berm rather than via the designed outlet. 1 have shot the elevations in this area and the
berm at this point is high enough not to overtop in the design storm.
• Perimeter slopes of Bioretention Cell 92 are insufficiently vegetated. The owner has overseeded these
areas and wil l continue to overseed until grass is better established. We have some concerns about how
well the seeding will germinate given the season. This fall we should be able to address this completely
but the Owner will continue to overseed until this is addressed.
• The forebay of Bioretention Cell #2 is clogged with sediment and vegetation. Prior to the site visit, the
sediment and vegetation had been removed and the forebay had been reconstructed.
• Infiltration Trench #3 has received excessive sedimentation from erosion of the inlet swale. The sediment
has been removed and new stone placed in the infiltration trench.
• Infiltration Trench 43 is not properly draining. I have observed all of the biocells and infiltration
trenches both 24 and 48 hours after a rain event and al I of them are infiltrating as designed.
• The vegetated filter strip below Infiltration Trench 43 is being bypassed by flow on both sides. As you
saw during the site visit, the owner has constructed a berm on both sides of the filter to keep the water on
the filter. This seems to have worked based on my recent site visits after rain events.

Portions of Infiltration Trench 41 and Infiltration 92 have been impacted by sediment which may be
clogging the media. The owner has cleaned off the fabric covering the trenches.
A portion of Infiltration Trench 42 has been breached and has been inappropriately repaired with riprap.
The trench is no longer providing the approved storage volume. As discussed on site, the owner has
installed a retaining wall and repairing the breach.
Slopes up -gradient oflnjiltration Trench 91 and Infiltration 92 are insufficiently vegetated. The owner
has overseeded these areas and will continue to overseed until grass is better established. We have some
concerns about how well the seeding will germinate given the season. This fall we should be able to
address this completely but the Owner will continue to overseed until this is addressed.
Stream Standard Violations:
Specifically, 1 5A NCAC 2B.0216 which references 1 5A NCAC 2B .0211 (3)(1) which states: Oils;
deleterious substances; colored or other wastes: only such amounts as shall not render the waters
injurious to public health, secondary recreation or to aquatic life and wildlife or adversely affect the
palatability offish, aesthetic quality or impair the waters for any designated uses; for the purpose of
implementing this Rule, oils, deleterious substances, colored or other wastes shall include but not be
limited to substances that cause a film or sheen upon or discoloration of the surface of the water or
adjoining shorelines pursuant to 40 CFR 110.4(a)-(b) which are hereby incorporated by reference
including any subsequent amendments and addition. The site investigation confirmed that as a result of
the construction activities and subsequent failure of slopes behind buildings 7, 8 and 9 and below
Infiltration Trench 42 sediment has been deposited in the stream. Approximately 200 feet of stream
impacts to an unnamed tributary to Muddy Creek occurred as a result of the land disturbing activities at
the subject site. These impacts represent a stream standard violation. As we discussed on site the
Owner will seed this area down with the same riprarian mix we used on the other steam by the end of this
week.

Dear Mr. Siegal:
On May 19, 2011, Sue Homewood, Robert Patterson and Brian Lowther of the Division of Water
Quality (Division) conducted an inspection of Robinhood Court Apartments to determine
compliance with the Stormwater Permit No. SW4090401. According to our records, the,first
phase of the facility opened for business in December 2009 and additional phases have continued
to be completed, and buildings occupied, throughout 2010.
The site inspection identified multiple violations and deficiencies with regards to DWQ
Stormwater Permit No. SW4090401 and State of North Carolina Stream Standards.

DWQ Stormivater Permit No. SW4090401:
The Division issued an approval letter for the Stormwater Management Facility on April 14, 2009
and a Modification was approved on October 12, 2009. The approval letter specifies that the
activities must follow the conditions listed in the permit.
I., Condition I16 states the following: "Upon completion of construction, prior to issuance of a
Certificate of Occupancy, and prior to operation of this permitted facility, a certification must
be received from an appropriate designer for the system installed certifying that the facility
has been installed in accordance with this permit, the approved plans and specifications, and
other supporting documentation."
• A file review has indicated that an engineer's certification has not been received for
Bioretention Cell #land Bioretention Cell #4. The Division is aware that Bioretention
Cell #1 could not be constructed until it was no longer necessary as a sediment basin.
Discussions with the Forsyth County inspections office has indicated that the project has
been determined to be stable and therefore conversion to a permanent stormwater control
structure must occur immediately.
2. Condition 11.6 of Permit No. SW4090401 states the following: "the facilities shall be
constructed as shown on the approved plans." The following violations were noted during
the site inspection:
• Bioretention Cell #4 was not located as shown on the approved plans.
• The vegetated filter strip at Bioretention Cell 94 does not appear to be the approved
length. J
• There was no evidence of a trench drain around the tennis court as shown in the approved.
plans to direct runoff to Bioretention Cell #4.
• Bioretention Cell #4 was missing the forebay as indicated in the approved plans.
• The roof drains behind building 7 do not drain to the infiltration trench as indicated on
the approved plans.
• The outlet structure (weir) of Bioetention Cell #3 appears to be at a similar elevation as
the planting elevation and therefore not providing the approved storage volume/ponding
depth.
• The vegetated filter strip at Bioretention Cell #3 does not appear to be the approved
length.
• The underdrain appears extend into the forebay of Bioretention Cell #3, which may allow
the runoff to bypass the filter media.
• The vegetation present in Bioretention Cell #2 and #3 does not match the approved
planting plans.
• Observation wells were not present in all locations within Infiltration Trench #1 or
Infiltration Trench #2.
Condition I1.3 of Permit No. SW4090401 states the following: "The permittee shall at all
time provide the operation and maintenance necessary to assure the permitted stormwater
system functions at optimum efficiency. The following maintenance violations were noted
during the site inspection:
• There are areas within Bioretention Cell #2 that do not have sufficient vegetation.

Requested Response
This Office requests that you respond to this letter in writing within 15 days of receipt of this
Notice. Your response should be sent to both this office at the letterhead address and to the
attention of Mrs. Karen Higgins at the Wetlands and Stormwater Branch, Wetlands, Buffers,
Stormwater Compliance and Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-
1617. Your response should address the following items:
Please clearly indicate what efforts you have taken to stabilize the site to prevent off -site
sedimentation. The site inspection noted that the silt fence adjacent to the stream on the
slope behind buildings has not been maintained and that the slope is not stable.
Regardless of the status of an approved erosion control plan, this issue should be
addressed immediatelv in order to avoid additional stream standard violations. In
addition, the area adjacent to the failed Infiltration Trench #2 should be
immediately stabilized until repaired and restored.
The site inspection noted that the remaining sediment basin has not been recently
maintained. During the inspection staff noted the basin was extremely full, the skimmer
did not appear to be working properly to drain the basin, and the outlet pipe could not be
located to inspect for any signs of clogging. The basin should be maintained and repaired
immediately. Failure of the sediment basin will result in multiple stream standard
violations.
3. An engineer's evaluation of all items listed as violations of Condition II.6 of Permit No.
SW4090401 above.
4. A comprehensive corrective action plan to address all items listed as violations of

should I hold off on the•modification until the case is closed? The only change appears to be replacing a bioretention
cell with a wet detention basin. It does seem strange though that they submitted a designers certification that the
bioretention cell they intend to replace with a wet detention basin was constructed and.compliant. ' - -

I received the revision of bioretention cell #1 to a wet detention basin. However, this will require a permit modification.
In addition to what you have submitted, you must also submit SWU-101 with revisions, application fee of $505, and
supporting calculations for the treatment volume using the simple method & drawdown time (be sure to use H/3 in'the
orifice equation).

plan and permit fo: your files. Please replace the existing stamped approved plan sheet C-10-F
(Bio-Cell Grass #3) with the enclosed stamped approved plan sheet C-10-F. Section 1.8 of the
permit was revised to reflect the changes in Cell #3.
Please be aware ihat all terms and conditions of the permit issued on October 12, 2009 remain in full
farce and effect. Please also understand that the -approval of this revision to the approved plans for
the subject State Stormwater Permit is done on a case -by -case basis. Any other changes to this
project must be submitted to and approved through the Division of Water Quality 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 contact Robert Patterson at (919) 807-

RE: Biocell #3 revisions for Robinhood Manor Apartment Homes
Dear Mr. Patterson:
Attached you will find two copies of revised plans, revised calculations, and a revised Bioretention Cell
Supplement for Biocell #3 at Robinhood Manor Apartment Homes. The contractor had to reconfigure
the Biocell in the field due to a clearing restriction imposed by the City of Winston-Salem. The plans are
of the existing Biocell as it is in place minus the forebay. They will be constructing the forebay in the
near future.

To: Michael Westcott <[e-mail]>
Michael,
I'm.following up the voicemail that I left for you this afternoon.
Regarding the three bioretention cells: The Session Law requires that the storage volume (volume as
calculated using the simple method) discharge at a rate less than or equal to the pre -development 1-yr,
24-hr discharge rate. These three cells do not appear to meet this requirement. Please revise as needed to
meet this requirement. Everything else looks good.
Please note that this request for additional information is in response to a preliminary review. ]'he
requested information should be received by this Office prior to April 27, 2009, 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
enforcement action pursuant to NCGS 143-215.6A.

Robinhood Manor Apartment Homes
Watershed Narrative
Robinhood Manor Apartment Homes is a 28.16 acre development in Forsyth to
NC, it is not located within a protected watershed and is not in the City limits of
Winston-Salem. The requirement for a 401/404 makes water quality control a
requirement for this site.
APR
D NR -' WATEi� "ALI
The site has been broken up into 6 sub -basins, each with its own water quality device.
Three of the BMPs are Infiltration Trenches and three are Bioretention Cells. Attached
you will find calculations, supplements, O&M agreements and plans for each BMP. You
will also find subsurface exploration reports for the areas of each BMP and those results
have been included in this narrative.
Infiltration Trench #1
Infiltration Trench #1 (IT1) is indicated on the watershed drainage area map as the
northern most yellow drainage area. It is a long narrow infiltration trench that runs along
the side of a slope. The drainage area for IT] is 3.71 acres with an impervious surface of
1.95 acres. The calculations can be found in the calculations packet. Water enters the
infiltration trench has two sections connected by a 24" pipe. This configuration is used to
keep the distance from down stream waters greater than 30'. The filter strip is longer that
the combined requirement for the two infiltration trenches combined. The Stormwater
Infiltration Report from the Catena group (Attached) indicates the infiltration rate for
trenches I and 2 to be 0.64 in/hr. The S&EC subsurface exploration report for this area
indicates that the seasonal high water table is greater than 84" deep which puts it at
greater than 2' deeper than our bottom of trench which is 60". There is an indication of
rock on two of the borings. One measurement is at 48" and the other at 80". Currently
the infiltration trench has been excavated and is currently being used as a sediment trap.
Rocks were found in the excavation but mass rock was not which would indicate that the
refusal was on a smaller rock and not on mass rock.
Infiltration Trench #2
IT2 is indicated on the watershed drainage area map as the northern most green drainage
area. It is another long narrow infiltration trench along the same hillside. The drainage
area is 2.98 acres with 1.45 acres of impervious surface. Again, the calculations are
included in the calculations packet. Water enters the trench by way of a forebay which
serves as pre-treatment. The forebay is isolated from the rest of the trench by 5' thick
earthen walls which serve as the weir for the water to enter the actual infiltration trench.
A bypass yard inlet has been provided to pass storms greater than the design storm and
leads to a grass filter strip that is shared with IT1. The overflow yard inlet from IT2
flows into the overflow box for IT1 and is then sent to the filter strip. The filter strip is
longer that the combined requirement for the two infiltration trenches combined. The
Stormwater Infiltration Report from the Catena group (Attached) indicates the infiltration
rate for trenches I and 2 to be 0.64 in/hr. The S&EC subsurface exploration report for
this area indicates that the seasonal high water table is greater than 84" deep which puts it
at greater than 2' deeper than our bottom of trench which is 60". There is an in icationECEIVED

of rock on borings 2 and 3. One measurement is at 18" and the other at 12". We have
stopped the trench short of the location of boring 44. Currently the infiltration trench has
been excavated and is currently being used as a sediment trap. Rocks were found in the
excavation but mass rock was not which would indicate that the refusal was on a smaller
rock and not on mass rock. As requested we have included a note on the master
watershed/final grading plan that the ISA from buildings 6-8 be directed to infiltration
trench 92.
Infiltration Trench 93
Infiltration "french #3 (IT3) is indicated on the watershed drainage area map as the blue
drainage area. It is located adjacent to buildings 25 and 26. Again a note on the master
watershed/final grading; plan indicates that all ISA from the buildings is to be directed
into IT3. The drainage area is 0.96 acres with 0.39 acres of impervious surface. Again,
the calculations are included in the calculations packet. Water enters the trench by way
ol'a forebay which serves as pre-treatment. Once the forebay fills with water it overflows
into the infiltration trench. Flows over the design now overflow the infiltration trench
into a level spreader and grass filter strip. The Stormwater Infiltration Report from the
Catena group (Attached) indicates the infiltration rate to be 0.84 in/hr. The S&EC
subsurface exploration report for this area indicates that the seasonal high water table is
greater than 84" deep which puts it at greater than 2' deeper than our bottom of trench
which is 60". There is no mention of rock. The site is currently a sedbasin and there has
been no indication of either seasonable high water table of rock in the excavation.
Bioretention Cell #1
Bioretention Cell # 1 (BC I) is indicated on the watershed drainage area map as red
drainage area. Located near the entrance of the complex the drainage area for BC is
8.29 acres with an impervious surface of 3.80 acres. The calculations can be found in the
calculations packet. This is a grass bioretention cell with an underdrain. We are not
using this cell for infiltration. Water enters the trench through two forebays that act a
pre-treatment. The forebays overflow into the BC2 as distributed sheet flow. The cell is
constructed of 2' of planting soil mix (specification and detail is on sheet C-10A)
covering 4" of washed sand. Under the washed sand is 30" of stone encased in filter
fabric. The underdrain system is encased in the washed stone. flows exceeding the
design flow exit the basin through a weir that leads to a level spreader and a grass filter
strip. The weir, grass filter strip, and level spreader have been sized to accommodate the
10 year storm. This cell has been excavated and is currently serving as a sedbasin for the
project. The sediment basin is currently excavated and with the contractors help several
holes were dug to look for seasonal high water table and bedrock and I verified that
neither was found to the 768 elevation.
Bioretention Cell 42
131oretention Cell 42 (BC2) is indicated on the watershed drainage area map as the
southern most yellow drainage area. Located near the back of the complex the drainage
area for BC2 is 2.92 acres with an impervious surface of 1.09 acres. The calculations can
be found in the calculations packet. This is a grass bioretention cell with an underdrain.
We are not using this cell for infiltration. Water enters the trench through a forebay that

01
acts as pre-treatment. The forebay overflows into the BC2 as distributed sheet flow. The
cell is constructed of 2' of planting soil mix (specification and detail is on sheet C-1 OL)
covering 4" of washed sand. Under the washed sand is 24" of stone encased in filter
fabric. The underdrain system is encased in the washed stone. Flows exceeding the
design flow exit the basin through a weir that leads to a level spreader and a grass filter
strip. The weir, grass filter strip, and level spreader have been sized to accommodate the
10 year storm. Since site was previously to be used for infiltration we do have an
infiltration rate from the Catena Group report of'O.004. Clearly this is unacceptable for
infiltration and the BMP was changed to bioretention. This site is currently in use as a
sedbasin. Again with the contractors help I verified the seasonal high water table to be
below 805.00 in the area. A note on the master watershed/final grading plan indicates
that all ISA from the buildings 21 and 22 is to be directed into BC2.
Bioretention Cell #3
Bioretention Cell 43 (BC3) is indicated on the watershed drainage area map as the
southern most green drainage area. Located near the back of the complex the drainage
area for BC3 is 0.46 acres with an impervious surface of 0.37 acres. The calculations can
be found in the calculations packet. This is a grass bioretention cell with an underdrain.
We are not using this cell for infiltration. Water enters the trench through a forebay that
acts as pre-treatment. The forebay overflows into the BC3. The cell is constructed of 2'
ofplanting soil mix (specification and detail is on sheet C-IOF) covering 4" of washed
sand. Under the washed sand is 24" of stone encased in filter fabric. The underdrain
system is encased in the washed stone. Flows exceeding the design flow exit the basin
through a weir that leads to a level spreader and a grass filter strip. The weir, grass filter
strip, and level spreader have been sized to accommodate the 10 year storm. Since site
was previously to be used for infiltration we do have an infiltration rate from the Catena
Group report of 0.20. Clearly this is unacceptable for infiltration and the BMP was
changed to bioretention. Again with the contractors help I verified the seasonal high
water table to be below 824.50 in the area. Flow from the parking lot enters the forebay
through a flume placed in the sidewalk.

Re:' Detailed Soils Evaluation Report for a Stormwater Infiltration Device, Pr
Robinhood Residential Development, Robinhood Road, Winston-Salem,
County, North -Carolina.
Dear tNlr. Segal:
Soil,-',,, Environmental,Colisultants, PA (S&EC) has performed a"detailed soils evaluation
in the proposed stormwater infiltration'areas at the site located adjacent to Robinhood
Road in Forsyth County, NC. A leap showing the location of the proposed stormwater
infiltration areas was'provided to us by the project engineer. There are two stonmwater
infiltration basins and two infiltration trenches proposed for this site. At the indicated
locations the following activities were performed: soil morphology profile descriptions
to seven feet, and estimation of permeability, hydraulic conductivity, and determination
of soil depth in relation to seasonal high water table and/or bedrock. The purpose of this
evaluation was to provide you with additional information for designing these stormwater
infiltration devices. The following is a brief report of the methods utilized in this
evaluation and the results obtained.
Soil/Site Evaluation
A site evaluation was performed by Walter Cole, Sarah Menser (NCLSS and NCSSIT) to
acquire the information you needed. The evaluation was performed by making hand
auger borings to a depth of seven feet at various locations within the proposed infiltration
basin and trench areas, which were located with. a GPS receiver and are shown on the
attached map and identifying and recording the soil morphological conditions at those
locations in order to develop soil profile descriptions, which are also included with this
report and shown on the attached map. The results of our evaluation are listed below.

Soil Borings 1, 4 were at various locations within the proposed 42"
as shown on the attached map. Soil Boring 1 had a seasonal high water table based on
soil morphology (munsell color) and depth to bedrock based on auger refusal, that was
>84". However, Soil Borings 2 & 3 were both shallow to bedrock and we had auger
refusal at 18'and.12" respectively. Soil Boring 4 had a seasonal high water table that .
was 30 inches from the soil surface, as a result of the perching effect of the underlying
clay subsoil with expansive mineralogy.
Soil Borings 5-7 were at various locations within the proposed "Infiltration-Treilelr #I`
as shown on the attached map. Soil Boring 5 & 6 had a seasonal high water table based
on soil morphology (munsell color) and depth to bedrock based on auger refusal that was
>80". However, Soil Boring 6 had auger refusal at 40", and depending.on the proposed
depth of the stormwater device, may be too shallow for use. Soil Boring 4 had a seasonal
high water table that was 30 inches from the soil surface.
Soil Borings 8 & 9 were within the proposed."Infiltration Basiu #3 & 411 respectively,
as shown on the attached map. Both Soil Borings 8 Sc 9 had a seasonal high water table
based on soil morphology (munsell color) and depth to bedrock based on auger refusal
that was >84".
Please note that some borings with low chroma colors in the C horizon were the result of
weathered parent material (saprolite) and are relic in nature and not indicative of seasonal
high water table.
The apparent (observed) water table was not measurable, however this is just a "snap-
shot" measurement; the reality is that the actual seasonal high water table is most likely
deeper than what is observed by soil color, especially with adjacent development but
shallower than was is observed by apparent water table. The only way to accurately
determine the seasonal high water table is to do put in test wells, monitor the site, and
perform a water table assessment. This service can be provided by our firm if requested.
Therefore, based on our evaluation the soil conditions on -site seem favorable with
respect to seasonal high water table and depth to bedrock for the areas with the proposed
infiltration basins 3 & 4 are located, however conditions are limiting in the areas where
the infiltration trenches 1 & I are proposed. The depth to bedrock, and ill one case
seasonal high water table, is a limiting factor in designing a stonmwater device. Along the
length of the proposed infiltration trenches, there were areas with greater than 50-60%
slope, that were located on complex topographic contours that were most likely the result
of underlying bedrock protrusions, that would Correspond to our field findings, and that
would make the design and installation of infiltration trenches difficult.
Pei-me:rbility/l-lydr,-itilic Conductivity Estimation
Under current regulations, soils underlying a stormwater infiltration device must have a
minimum infiltration rate of 0.52 inches per hour or greater [ 15A NCAC 02H .1008 (d}
(6)]. Based on our evaluation, most all soil borings bad subsurface horizons that have an

estimated hydraulic conductivity of less than the 0.52 inches per hour threshold. Please
refer to the enclosed map and soil profile descriptions for more information. Although
on -site saturated hydraulic conductivity measurements would be needed to definitively
show that these layers are below the 0.52 inches per hour threshold, we feel strongly that.
any testing will reveal that these soils will not meet the threshold, and that, depending on
the depth of the proposed stormwater device, the excavation of some of the soil horizons
and replacement with clean sand would be necessary and must be proposed to NCDWQ
for them to approve on a case -'by -case basis.
All of these *estimates obtained frorn one or more of the following: Forsyth County Soil
Survey Table 1 S_ "Physical & Chernical Properties of the Soil - Permeability"; J acolet
Soil Series and/or USDA-NRCS (United States Department of Agriculture - Natural
Resource Conservation Service) official series description, and/or "NRCS Field Book for
Describing & Sampling Soils" and since the rules require a minimum hydraulic
conductivity of 0.52 inches per hour or more, the permeability estimates were converted
to conductivity on the profile description tables. No actual site specific testing of
hydraulic conductivity was performed, however this service can be provided by our firm
if requested. .
In conclusion, please remember that the rules require a 30 foot setback to all surface
waters, a 50 foot from SA. waters, and 100 foot from any water supply wells from the
stormwater infiltration device.
Soil & Environmental Consultants, PA is pleased to be of service in this matter and we
look forward to assisting in the successful completion of the project. Please feel free to
call with any quest oq pmments.

Dear Mr. Siegal:
OCT 14 2W9
Winston-Salern
riles Reglonal office
Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit
Modification Application for Robinhood Court Apartment Homes on September 21, 2009. Staff
review of the plans and specifications has determined that the project, as proposed, will comply
with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session Law 2006-
246. We are forwarding Permit No. SW4090401, dated October 12,-2009, for the construction,
operation and maintenance of the subject proJ'ect and the stormwater BMPs. This modified
permit includes the additional bioretention cell (Cell #4); and does not change the overall bua or
the previously approved BMPs.
This permit shall be effective from the date of issuance until April 14, 2019, and shall be subject
to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system
for inspection and maintenance of the stormwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this

Robinhood Manor Apartment Hornes
Watershed Narrative
Robinhood Manor Apartment Homes is a 28.16 acre development in Forsyth County,
NC. It is not located within a protected watershed and is not in the City limits of
Winston-Salem. The requirement for a 401/404 makes water quality control a
requirement for this site.
The site has been broken up into 7 sub -basins, each with its own water quality device.
Three of the BMPs are Infiltration Trenches and four are Bioretention Cells. Attached
you will find calculations, supplements, and plans for Bioretention Cell 44.
Bioretention Cell #4
Bioretention Cell #4 (BC4) is indicated on the watershed drainage area map as red
drainage area. Located near the tennis courts for the complex the drainage area for BC4
is 0.57 acres with an impervious surface of 0.17 acres. The calculations can be found in
the calculations packet. This is a grass bioretention cell with an underdrain. We are not
using this cell for infiltration. Water enters the trench through a forebay that acts a pre-
treatment. The forebays overflow into BC4 as distributed sheet flow. The cell is
constructed of 2' of planting soil mix (specification and detail is on sheet C-I OG)
covering 4" of washed sand. Under the washed sand is 24" of stone encased in filter
fabric. The underdrain system is encased in the washed stone. Flows exceeding the
design flow exit the basin through a weir that leads to a level spreader and a grass filter
strip. The weir, grass filter strip, and level spreader have been sized to accommodate the
10 year storm. The contractor excavated several holes to look for seasonal high water
table and bedrock and I verified that neither was found to the 784.50 elevation.
