Storm water Impact Analysis and Design of Storm water Managemen���c�tX �p �OJ,
General Description and Background PDP�iasP� P
%/ 46O
The Isaacs Group proposes the expansion of a commercial development at 1310 Wesley Chape ad in
Union County, North Carolina. The existing site is approximately 7.54 acres and features existing
buildings, utilities, parking, and a detention basin. The proposed additions will feature the construction
of a ±25,045 square foot commercial storage building on -site.
The proposed development drains to East Fork Twelve Mile Creek, a class 'C' surface water, located
within the Catawba River Basin. Stormwater from the development falls under the jurisdiction of The
State's Phase II requirements.
Requirements are as follows:
1. Utilize Stormwater control measures that control and treat runoff from the first one inch of rain,
and;
2. The runoff volume drowdown time shall be greater than 48 hours, but no more than 120 hours,
and,
3. Design all structural Stormwater treatment systems to achieve 85% average annual removal of
total suspended solids, and,
4. Utilize Stormwater management measures according to the requirements in the NCDEQ BMP
Manual.
To address the applicable Stormwater management requirements, a grassed bioretention facility is
proposed. The proposed facility is designed in accordance with Chapter 12 of the NCDEQ Stormwater
BMP Manual in order to treat the additional impervious area added to the site. This report contains
calculations detailing the design of the Stormwater management facility. Please refer to the appropriate
sections for more information.
Calculations
• Rainfall data is from NOAA Atlas 14, Volume 2, Version 3, Station 31-5771 Monroe 4 SE. This
data describes a depth -duration -frequency (DDF) table describing rainfall depth versus time for
varying return periods in the Monroe, NC area. These rainfall depths were input into the
meteorological model within Pond Pack for peak flow rate calculations. Please reference the
rainfall data section.
• Using the NRCS Web Soil Survey, the on -site soils were determined to be from hydrologic soul
group (HSG)'D' soils.
• A composite SCS curve number was calculated for the post -construction condition.
• The post -development time of concentration was assumed to be 5 minutes.
• PondPack Version VBi, by Haestad Methods, was used to calculate stormwater routing through
the stormwater management facility.
Discussion of Results
The stormwater management facility meets the design requirements set forth in the NCDEQ BMP
Manual. The stormwater facility is designed to treat the first inch of rainfall from the new impervious
area proposed via roof drains leading from the building to the facility. Large flows to the facility will be
bypassed by restricting flows to the roof drains using secondary overflow structures. In addition, the
facility contains an emergency spillway and a concrete riser to quickly outlet large storm events. Please
refer to stormwater routing calculations in this report for more details.

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.
