Stormwater Management Report June 7, 2022
1.0 Project Address and Summary
The project is located on Maye Street, approximately 0.60 miles northwest of the intersection of Edgewood
Drive and Maye Street. The proposed development will include the construction of 119 single family homes
and the associated site grading, roadways, stormwater management facilities, and landscaping. Phase 1 of the
property to the southeast was approved with 180 single family homes and the associated infrastructure to
serve these homes.
Site improvements will include the site grading, paving, storm drain systems, public roadways, and one wet
pond storm water device. This device, in addition to the existing Stormwater Pond #A1 from Phase 1, will
treat all proposed single-family homes and infrastructure for Phase 2 (with Stormwater Pond #A1 also
treating a portion of the associated impervious for Phase 1). Stormwater Pond #A1 was sized in Phase I to be
able to manage and treat the additional impervious from Phase 2.
As mentioned above, the site will include the construction of one stormwater BMP located adjacent to the
western side of the stream that splits the site in two, at the topographical low point of the drainage shed. In
addition to this BMP, the site will also utilize the existing Stormwater BMP #A1 from Phase 1 to manage and
treat a portion of the area of Phase 2. The development of the site must comply with the City of Wingate
Stormwater Management Ordinance and therefore will provide stormwater quality and provide peak controls
for stormwater runoff of the 2- and 10-year storm events while providing safe conveyance of the 100-year
storm event. The BMP chosen was a single wet pond to provide for both WQv and detention designed per the
NCDEQ Stormwater BMP Manual.
Runoff calculations were performed following the procedures outlined in the NCDEQ Stormwater BMP
Manual and by the SCS method.
The receiving drainage system for this site is an existing channel/stream located on -site, which splits the site
in half, and flows to the southwest until it leaves the property along the western property line, at which point
the stream continues to the north.
Soils on the site consist of:
• BdB2: Badin channery silty clay loam, 2 to 8% slopes
• BaC: Badin channery silt loam, 8 to 15% slopes
• ChA: Chewacla silt loam, 0 to 2% slopes
• GsB: Goldston-Badin complex, 2 to 8% slopes
• GsC: Goldston-Badin complex, 8 to 15% slopes
• GsE:Goldston-Badin complex, 15 to 45% slopes
• TaB: Tarrus gravelly silt loam, 2 to 8% slopes
• TbB2: Tarrus gravelly silty clay loam, 2 to 8% slopes
This on -site soils are labeled as hydrologic soil group (HSG) "B", "C", and "D". A USDA NRCS soils map
and supporting information can be found in the Appendix A.
2.0 Water Quality Volume Control and Peak Flow Control
Water Quality Volume and Release Rate calculations were performed as outlined in Appendix B.

Stormwater Management Report June 7, 2022
3.0 Predeveloped Conditions
Under existing conditions, the site is an undeveloped property consisting primarily of woods in good
condition with a large area of open fields in good condition. There are no existing structures on -site.
The site has 3 different streams that split the site into 3 different sections. The section to the east and adjacent
to Edgewood Road is the largest section and the area that consists of Phase 1. The section between the
western most channels is a smaller area, but will be the land that contains Phase 2 of the development.
Finally, the section of land to the far west is split my an existing channel, but will be undeveloped. All of
these sections drain to the 3 different streams and the floodplain located to the far west of the site along the
boundary. Although the site all drains to the floodplain, there are 2 distinct drainage areas for the purposes of
this development. One drainage basin that consists of all the land of Phase 1 (and uphill drainage) and one
drainage basin that consists of all of the land of Phase 2 of the development (and all uphill runoff). The
easternmost portion of the site (Phase 1) is the largest drainage basin and drains from east to west into the
previously mentioned existing channels and 100-year floodplain. The point at which this stream enters the
floodplain was considered the study point (Point of Analysis A). This drainage shed has a rather large portion
of offsite drainage in the southeast which makes its way onto the site. However, bypass swales will be utilized
to divert much of this offsite drainage away from the site.
The predevelopment drainage from the site was delineated as indicated on the Pre Development Drainage
Area Map included in Appendix B. The pre -development time of concentration calculations utilize a
combination of overland sheet flow and shallow concentrated flow to determine the longest possible scenarios
with a minimum 5 minute time interval. These calculations are outlined in Appendix B.
The Curve Number (CN) for the pre -development basin was computed as a combination of woods and open
areas (fields) with some impervious. Offsite areas used actual condition curve numbers where applicable.
These calculations resulted in a predevelopment CN of 72 for the drainage area of Phase 2. A NRCS soil data
table (Table 8.03e) from the NCDEQ Erosion and Sediment Control Planning and Design Manual depicting
the soils designation for the site is included in Appendix A.
4.0 Post Developed Conditions
The proposed development will include the construction of 119 single family detached homes, pavement and
hardscape with associated site grading. Phase 2's drainage area will utilize one proposed BMP on the west of
the existing stream that splits the site in half and it will also utilize the existing BMP #A1 from Phase 1 on the
east of this stream as well to provide the required water quality and detention volumes. The proposed BMP is
a wet pond (B) located adjacent to the existing stream on the west side, not far west from the roadway
crossing connecting Phase 1 and Phase 2. The pond is located at the topographical low point of its' drainage
basin on the site and outfalls to the southeast toward the stream channel that cuts the site in half between
Phase 1 and Phase 2. This pond measures approximately 360' x 135' and contains two separate forebays and
a single outfall control structure. The existing BMP that manages stormwater for Phase 2 is an existing wet
pond in Phase 1 of the development (Al) and is located adjacent to the stream that cuts the site in half, on the
east side of the stream. This BMP measures approximately 505' x 160' and contains 2 separate forebays as
well as a single outfall structure. These 2 BMP's will capture runoff from the entirety of Phase 2.
Both of these devices are being utilized for primary detention as well as for water quality treatment. They
have been modeled to mitigate the sites requirements for post development flow and water quality.
Calculations in Appendix B (see Hydrograph Return Period Recap, Page 1) have been provided to show that

The Cottages at Wingate 7516-C-NC
Stormwater Management Report June 7, 2022
the detention system is adequately sized for the 2-year and 10-year storm events, and adequately size to safely
convey the 100-year 24-hour storm event. Any increase in peak flow in the bypass drainage sheds from Pre
and Post development conditions has been accounted for with the over -detention of the flow from the
development onsite within each wet pond.
The composite Curve Numbers were calculated for each post developed basins and are summarized below.
• Pre -Development Area: 72
• Post Development Area B: 83
• Post Development Area Al: 83
• Post Development Area Bypass: 73
See Post Development Drainage Area Map.
A comparison of pre -developed, post -developed, and detained peak flows is shown below. The pre -
development peak flows (Hyd. No. 1) should be compared to the total post -development peak flows (Hyd.
No. 5). The drainage area reduces its' respective peak flow rates from pre -developed to post -developed
conditions utilizing the wet pond detention. These BMPs's have been oversized to account for the un-detained
flows from the respective bypass drainage sheds. Complete calculations including time of concentration and
full hydrographs for the 2-year, 10-year, and 100-year 24-hour storm events are included in Appendix B.

5.0 Stormwater System
The storm water system consists of proposed reinforced concrete pipes, ranging in size from 15" up to 36",
conveying runoff to the proposed BMP's through a combination of underground pipes and catch basins.
Adequate cover has been provided for all pipes and all pipes are proposed as class 3 and class 4 reinforced
concrete pipe. The system has been modeled for a 10-year storm event for capacity and HGL. The results of
the system have been provided in Appendix C.
6.0 Erosion Control
Erosion control will be provided by utilizing temporary sediment basins, perimeter silt fence, temporary
diversion ditch, and inlet protection where necessary. These mechanisms will be in place until the project is
stabilized. Upon approval of the NCDEQ inspector, these mechanisms can be removed and the final storm
drain measures can be put in place. Calculations for the sediment traps and sediment basins have been
provided in Appendix D.

Hydrologic Soil Group —Union County, North Carolina
Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long -duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink -swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.

1. Average runoff condition, and la = 0.2S.
2. The average percent impervious area shown was used to develop the composite CN's. Other assumptions are as follows: impervious
areas are directly connected to the drainage system, impervious areas have a CN of 98, and pervious areas are considered equivalent
to open space in good hydrologic condition. CN's for other combinations of conditions may be computed using Figure 8.03c or 8.03d.
3. CN's shown are equivalent to those of pasture. Composite CN's may be computed for other combinations of open space cover type.
4. Composite CN's to use for the design of temporary measures during grading and construction should be computed using Figure 8.03c
or 8.03d based on the degree of development (impervious area percentage) and the CN's for the newly graded pervious areas.
