Re: Pre - Construction Notification — GC 3890 Authorization Request
Providence Retreat
Charlotte, North Carolina
CSH -14000
Dear Mr. Parker:
On behalf of Classica Homes, McAdams is submitting a Preconstruction
Notification for approval of 401 Water Quality General Certification 3890
associated with the proposed Providence Retreat development is a single -
family residential development, and more specifically, a road crossing aligned
across an unnamed tributary to Rocky Branch. The proposed Providence
Retreat development is located along Country Lane, approximately 0.33 -miles
east of its intersection with Providence Road in Charlotte North Carolina. No
additional impacts to waters of the U.S. are proposed. Please find enclosed

PROJECT HISTORY & EXISTING CONDITIONS:
The subject property lies within the Catawba River basin and within the City
of Charlotte. The current Mecklenburg County zoning is R -3 Residential.
Land use within the vicinity of the subject property is residential, institutional,
and forested areas. The subject property can be characterized as residential,

containing one residential structure and one shed. Approximately 70 percent
of the subject property is maintained lawn. 'The remaining 30 percent can be
generally characterized as a Dry Mesic Oak - Hickory Forest according the NC
Natural Heritage, Program classification system. The forested areas are located
mostly within the northern and western portions of the subject property. One
perennial stream feature, which is an unnamed tributary to Rocky Branch, is
observed within the northern section of `the subject property. There is an
existing 15 foot wide driveway entrance crossing of the unnamed tributary to
Rocky Branch located in the extreme northwestern section of the property.
Mr. William Elliott (USACE representative) attended an on -site field
concurrence meeting on January 9, 2014 and concurred with the wetland
delineation.
PROPOSED PROJECT:
The proposed Providence Retreat development is a single - family residential
development. The proposed development will consist of approximately 16
single - family lots along with associated roadway, utility, and stormwater
management improvements. To gain access to the subject property, a
proposed road crossing will be aligned across an unnamed tributary to Rocky
Branch. As a result, there are proposed stream impacts associated with the
road crossing. Additional impacts to the unnamed tributary to Rocky Branch
located within the project area not proposed.
Impact Table
Stormwater Management
The proposed development is located within the Catawba River basin with
stormwater runoff from the proposed development draining into Rocky
Branch. Per City of Charlotte regulations; stormwater management on this site
shall meet the stormwater management performance standard's for
development set forth in the Charlotte Post Construction Control Ordinance.
The proposed project will result' in a significant increase in peak flow rates to
downstream properties. To mitigate these impacts, the proposed stormwater

management facility has been sized such that post - development peak flow
rates are no greater than pre- development levels in the 10 -, and 25 -year storm
events on site. The proposed stormwater wetland is, designed as "TSS -only
efficiency" stormwater wetland according 'the Chapter 4.3 of the Charlotte
Mecklenburg BMP Design Manual (Revised July 1, 2013). The proposed
stormwater Wetland will provide the required 85% TSS removal as well as the
70% total Phosphorus removal required in this watershed. If the development
on this tract is built as proposed within this report, then the .requirements set
forth, in City of Charlotte regulations will be met without additional
stormwater management facilities. However, modifications to the proposed
development may require that this analysis be revised.
AVOIDANCE & MINIMIZATION:
Impacts to the jurisdictional stream located on the subject property have been
avoided and minimized to the maximum extent practicable; however, due to
infrastructure improvements there are proposed impacts. The existing 15 foot
wide driveway access crossing is currently undersized and structurally
inadequate to accommodate the proposed infrastructure and residential
improvements to the subject property. In addition, the existing driveway
access crossing is located within the extreme northwestern corner of the
subject property. This current alignment causes sighting issues for oncoming
traffic along Country Lane. It would be more conducive, for oncoming traffic,
if the entrance to the subject property were aligned more with the adjacent
driveway entrance located on the opposite side of Country Lane. Therefore,
the proposed crossing alignment into the subject property has been re- aligned
to the east almost, directly opposite of the opposing driveway across, from
Country Lane. In addition, the proposed crossing alignment has been aligned
as close to 90 degrees as possible along the most narrow stream section to
accommodate the necessary road width to access the residential community
and culverts to accommodate the volume of water within the existing stream.
To minimize, the, existing, 15 foot driveway, access wide crossing will be
removed and the stream bank_ s will be stabilized' `to allow for natural stream
formation to occur.
SUMMARY:
The proposed Providence Retreat development is a single - family residential
development. The proposed development will consist of approximately 16
single- family lots along with associated roadway, utility, and stormwater

management improvements. Mr. William Elliott (USACE representative)
attended an on -site field concurrence meeting on January 9, 2014 and
concurred with the wetland delineation. To gain access to the subject
property, a proposed road crossing will be aligned across an unnamed
tributary to Rocky Branch resulting in 145 linear feet of stream impacts. The
proposed project is a single and complete project and confined within the
property boundary. Appropriate, land .use control measures will be in place for
areas which will require them. Additional impacts to the unnamed tributary to
Rocky Branch are not proposed. In addition, compensatory mitigation is not
proposed as a result of the proposed impacts.
At this time, we are requesting approval that the proposed construction
activities associated with the Providence Retreat development are authorized
under 401 Water Quality General Certification 3890. Consideration of this
project is greatly appreciated. If you should have any questions or require
additional information, please do not'hesitate to, contact me at, (919) 287 -0890.

jurisdictional stream located on the subject property have been avoided and minimized to the maximum extent practicable,
however, due to infrastructure improvements there are proposed impacts The existing 15 foot wide driveway access crossing
is currently undersized and structurally inadequate to accommodate the proposed infrastructure and residential improvements
to the subject property In addition, the existing driveway access crossing is located within the extreme northwestern corner-,of
the subject property This current alignment causes sighting issues for oncoming traffic along Country Lane It would be more
conducive for oncoming traffic, if the entrance to the subject property were aligned more with the adjacent driveway entrance
located on,the opposite side,of Country Lane Therefore, the proposed crossing alignment into the subject property has been

stream banks will be stabilized to.allow for natural stream formation to occur -
1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques Proper
sedimentation, and erosion control methods will be utilized during all phases of construction and installation as,descnbed in the
Erosion Control Plan sheet reviewed and approved by the NC Division of Land Quality and City of Charlotte All work will take
place °during dry conditions and can be facilitated from high, non - jurisdictional, stable ground The contractor shall install silt
fence, inlet protection; sediment traps, diversion ditches, tree protection, clearing only as necessary to install,devices All
erosion and-sediment control measures,will be checked for stability and operation following every runoff producing rainfall', but
in no case less than once every week Any needed repairs will be made immediately to maintain all measures designed An
erosion control inspections report is required and will be kept by the owner's representative Temporary seeding and

X No
6b What data sources did you use to determine whether your site would impact Essential Fish Habitat? An interactive map
called the Essential Fish Habitat (EFH) Mapper (http / /www habitat noaa gov /protection /efh /efhmapper /) was accessed on
June 16, 2014 to determine if the project will impact Essential Fish Habitat
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a Will this project occur in or near an area that`the state, federal or tribal
governments have designated as having historuaorcultural preservation
X No
status (e g , National Historic Trust designation or properties significant

What data sources did,you use to determine whether your site would impact historic or archeological resources? A review of
the list of properties and districts in the North Carolina in the National Registry of Historic Places
(hhtp / /www Kpo ncdcr, gov /nrlist htm) was conducted and a preliminary field assessment was conducted for the subject
property Based on the review and field assessment, the proposed project will not occur in or near an area that has been
designated as having historic or cultural preservation status by the state, federal, or tribal governments
8. Flood Zone Designation (Corps Requirement)
8a Will this, project occur in a FEMA- designated 100 -year floodplain?
X No
8b If yes, explain how project meets FEMA requirements
8c What source(s) did you use to make the floodplain determination? The North Carolina, Flood Insurance, Rate Map ,
,3710447800J (issued March 2, 2006) was reviewed and it does not show 100 -year flood area or floodway located on'the
subject property

PROVIDENCE RETREAT
Stormwater Impact Analysis and Final Design of Stormwater Management Facility
General Description
Located along Country Lane, approximately 0.33 -miles east of its intersection with Providence
Road in Charlotte North Carolina, is the proposed single - family residential development
currently known as Providence Retreat. Proposed development on this site will consist of the
construction of 16 single - family homes, along with associated roadway, utility, and stormwater
management improvements.
The proposed development is located within the Catawba River basin with stormwater runoff
from the proposed development draining into Rocky Branch. Per City of Charlotte regulations,
stormwater management on this site shall meet the stormwater management performance
standards for development set forth in the Charlotte Post Construction Control Ordinance. These
are as follows:
,Sec. 18 -141 Standards for the Central Catawba District
(b)- Standards for high density protects, Any drainage area within a project boundary in the Central
Catawba ,district is considered high density when said drainage area has greaten than 24 percent built
upon area as determined by the methodology established in the design manual Such high- density
projects shall implement stormwater treatment systems that comply'with each of the following standards
(1) Stormwater quality treatment volume. Stormwater quality treatment systems shall treat the
runoff generated from the first inch of rainfall
(2) Stormwater quality treatment All structural stormwater treatment systems used to meet
these requirements shall be designed to, have a minimum of 85% average annual removal for
total suspended solids Low impact development techniques as described in the design
manual can be used to meet this requirement
(3) Stormwater treatment system design General engineering design criteria for all projects
shall be in accordance with 15A NCAC 2H 1008(c), as explained in the design manual-
(4) Stream buffers The S W I M stream buffer requirements apply, in the Central Catawba as
described in the city's zoning ordmance, chapter 12. In addition, intermittent and perennial
streams_ within the project boundary shall be delineated by a certified professional using
U S Army Corps of Engineers and N C' Division of Water Quality methodology and shall be
shown in ,the stormwater manageriient permit application along with all buffer areas All
perennial and intermittent streams draining less than 50 acres shall have a minimum 30foot
vegetated buffer ,including a ten foot zone adjacent to the bank Disturbance of the buffer is
allowed, however, any disturbed area must be revegetated and disturbance of the ten foot
zone adjacent to the bank shall require stream bank stabilization using bioengineering
techniques as specified in the design manual- All perennial and intermittent streams draining
greater ,than or equal to 5,0 acres and less than 300 acres shall have a 35 foot buffer with
two zones, including stream side and upland Streams draining greater than or equal to 300
acres and less than 640 acres shall have a 50 foot buffer with three zones, including stream
side, managed use and upland Streams draining greater than or equal to 640 acres shall
have a 100 foot buffer, plus 50 percent of the area of the flood fringe beyond 1,00 feet This
buffer shall consist of three zones, including stream side, managed use and upland All
buffers shall be measured from the top of the bank on both sides of the stream The uses
allowed in the different buffer zones as described in the S. W I M stream buffer requirements
in the jurisdiction's zoning ordinance, chapter 12, as well as the other provisions of the
S W I M ordinance shall apply in the Central Catawba district (except buffer widths)
(5) Stormwater volume control Stormwater treatment systems shall be installed to control the
volume, leaving the project site at post- development for the one -year, 24 -hour storm except I-
1 and I -2 zoned developments which are exempt from, this requirement Runoff volume
drawdown time shall be �a „mmimufii of 48 hours, but,not7more than 1,20 hours
(6) Stormwater peak control For residential land disturbing activities exceeding 24 percent
built -upon area, peak control shall be installed for the, appropriate storm frequency (i e,
10 -, 25 -, 50- or 100 year, six -hour) as determined by the, flood analysis provided by the
owner or designee using the criteria specified in the design manual or if a downstream,
analysis is not performed the peak shall be controlled for °the ten-year and 25 year, six -hour
storms For commercial land disturbing activities exceeding 24 percent built -upon area,
peak control shall be installed for the ten-year, six -hour storm and additional peak control
provided for the appropriate storm frequency (i e, 25 -, 50- or 100 year, six -hour) as
determined by the stormwater administrator based on a downstream flood analysis provided
by the owner or designee using the criteria specified in the design manual or if a
downstream analysis is not performed the peak shall be controlled for the ten-year and 25-
year, six -hour storms Controlling the one-year, 24 -hour volume achieves'peak control'for
the two -year, six -hour storm For I -1 and I -2 zoned developments, peak control shall' be
installed for 'the two-year and ten-year, six -hour storms and additional peak control
provided for the appropriate storm frequency (i e, 25 -, 50- or 1,00 year, six -hour) based on a
downstream flood analysis or f a downstream analysis is not performed the peak shall be
controlled for the two-year, ten-year and 25 -year, six -hour storms The emergency overflow
and outlet works for any pond or wetland constructed as a,stormwater BMP shall be capable
of safely passing a discharge with a minimum recurrence frequency as specified in the
design manual For detention basins, the temporary storage capacity shall be restored within
72 hours Requirements of the Dam Safety Act shall be met when,applicable
To meet the above stormwater management standards,, a stormwater wetland is proposed. Please
refer to the appropriate section of this report for additional information.
Calculation Methodolozy
• Rainfall data for this analysis was taken from the City of-Charlotte BMP Design Manual.
Please reference the precipitation information section within this report for additional
information.
Using maps contained - within the Mecklenburg County Soil Survey, the on -site soils were
determined to range from hydrologic soil group (HSG) `B' soils to HSG `C' soils. Since
the method chosen to compute pre- and post- development peak flow rates and runoff
volumes is' dependent upon the soil type, care was taken when selecting the appropriate
Soil Conservation Service Curve Number (SCS, CN). A composite SCS CN was
computed for each pre- and post - development sub - basin. For example; Subbasin # 1 A in
the pre - development analysis consists of approximately 64% HSG `B' soils and 3,6%
HSG `C' soils. Therefore, for the open area cover ,condition, the composite SCS CN is
computed as follows (assuming good condition):
Composite Open SCS CN = (64% x 61)+ (36% x 74) = 66
• A composite SCS Curve Number was calculated for both the pre- and post - development
condition for each ,subbasin using ,SCS curve numbers and land cover conditions. Land
cover conditions for the pre- development condition were taken from recent survey
prepared by The John R. McAdams Company, Inc. and Mecklenburg County GIS. Land
cover conditions for the post - development condition were taken from the proposed
development plan.
• For the ,purposes of computing the pre - development storm events, a 50% open and 50%
wooded condition was assumed for the sub - basins yielding less than 50% wooded area in
pre - development conditions.
• The upstream drainage areas shown in this analysis stop at the property line in order to
effectively control runoff from the site without "watering down" the impact from the
proposed development. Please note that no offsite drainage is directed to the stormwater
facility.
• The time of concentration was calculated using SCS TR -55 (Segmental Approach, 1986).
The Tc flow path was divided into three segments: overland flow, concentrated flow, and
channel flow. The travel time was then computed for each segment, from which the
overall time of concentration was determined by taking the sum of each segmental time.
• The post - development time of concentration to the proposed stormwater management
facility is assumed to be 5 minutes. This provides a, conservative estimate of facility size
for design, purposes.
• PondPack Version V8i was used in determining the pre- & post - development, peak flow
rates for the 10 -, 25 -, and 100 -year storm events, as well as routing calculations for the
proposed stormwater management facility.
• A stormwater wetland is proposed on this site to treat / manage stormwater runoff from,
the proposed development. This facility is based on City of Charlotte design standards.
• For 100 -year storm routing calculations, a "worst case condition" was modeled in order to
insure the proposed facility would safely pass the 100 -year storm event. The starting
water surface elevation in each facility, just prior to the 100 -year storm event, is at the
secondary spillway elevation. This scenario could occur as a result of a clogged siphon or
a rainfall event that lingers for several days. This could also occur as a result of several
rainfall events in a series, before the siphon has an opportunity to draw down the storage
pool.
Discussion of Results
Peak.Runoff Control Requirements
`The, proposed project will result in .a significant increase in peak flow rates to downstream
ro
pperties. To mitigate these impacts, the proposed stormwater management facility has been
sized -such that post - development peak flow rates are no greater than pre - development levels in
the 10 -, and 25 -year storm events on site.
Pollutant and Nutrient Control Requirements
The proposed stormwater wetland is designed as "TSS -only efficiency" stormwater wetland
according the Chapter 4.3 of the Charlotte - Mecklenburg BMP Design Manual (Revised July 1,
2013). The proposed stormwater wetland will provide the required 85% TSS removal as well as
the 70% total Phosphorus removal required in this watershed.

Conclusion
If the development on this tract is built as proposed within this report, then the requirements set
forth in City of Charlotte regulations will be met without additional stormwater management
facilities. However, modifications to the proposed development may require that this analysis be
revised. Some modifications that would require this analysis to be revised include:
1. The proposed site impervious surface exceeds the amount accounted for in this report.
2. The post - development watershed breaks change significantly from those used to prepare
this report.
The above modifications may result in the assumptions' within this report becoming invalid. The
computations within this report will need to be revisited if any of the above conditions become
apparent as development of'the proposed site moves forward.
