Aldi East Spencer In -bound Traffic Improvements
Project Narrative
Aldi, Inc, currently operates a distribution warehouse facility at 1985 Old Union Church Road in East
Spencer, NC. The original warehouse facility was constructed in 2000 with subsequent building
additions and site modifications in 2007. No permanent stormwater control measures were included
with previous construction and none currently exist on the property. The site encompasses roughly
273.3 acres and splits two major drainage basins with roughly 170 acres draining to Town Creek and 103
acres draining to Crane Creek, both Class C waters. Existing surface waters on the property total
approximately 1.35 acres, including portions of Town Creek and two unnamed tributary streams,
yielding a net site area of 271.95 acres. The existing built upon area within the property measures
approximately 25.5 acres, or 9.38% impervious. Accordingly, the site generally qualifies as low density
under stormwater rules. The current project will add improvements to aid in in -bound truck traffic
management (stacking and parking areas) along with employee and contractor parking. In total, the
proposed improvements will add approximately 6.2 acres of new built -upon area. For purposes of
stormwater permitting, the site should continue to qualify as low density based on the following:
Project Density = 6.2 acres / (271.95 acres — 25.5 acres) = 2.5%
In compliance with low density design requirements, the new driveway and parking areas have been
designed either without curb and gutter (except at required tree islands) or with regularly -spaced curb
cuts to allow stormwater runoff to sheet drain overland through existing vegetated areas or discharge to
new grass swales to the extent practical. At the entrance driveway low point, drainage collected from
the roadside ditches is to be piped under the pavement and down the adjacent fill slope to a stabilized
outlet at the base of slope (Drainage Structures STCB-2 to HW-1). This drainage system will collect
approximately 4.2 acres of drainage area with an associated 10-year discharge of approximately 26.9 cfs.
Accordingly, a pipe will be used to control the drainage and maintain stable slope conditions.
Approximately 500 LF of vegetated outfall swale exists beyond the toe of slope to the downstream
discharge point at the property line.
All proposed construction and stormwater outlets will occur at least 300 LF upland of any existing
surface waters and will drain through existing vegetated buffers that are to remain. Grass swales and
stormwater outfalls have been designed to convey the 10-year design runoff in a non -erosive manner as
documented in the attached calculations.

Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a
given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.
