Reference: Report of Stream/Wetland Delineation
Approximate 34.31 Acre Tract
Old Jackson Lake Road
High Point, North Carolina
ECS Project No. G-13491
Dear Mr. MacEldowney:
ECS Cazolinas, LLP (ECS) is pleased to submit this report of the jurisdictional waters/wetland delineation
for the site located on Old Jackson Lake Road in High Point, North Carolina. This report summarizes our
findings for the site.
Background
ECS was contracted to identify the locations of waters of the U.S., including wetlands, for the above
referenced site. The site is developed with a Larco Asphalt Plant. Portions of the site contain
undeveloped, wooded land.
Wetlands are defined by the U.S. Army Corps of Engineers and the United States Environmental
Protection Agency as "those azeas that are inundated or saturated by surface or groundwater at a
frequency and duration sufficient to support, and under normal circumstances, do support a prevalence of
vegetation typically adapted for life in saturated soil conditions." In order for an area to be classified as
wetland, hydrophytic vegetation, hydric soils, and wetland hydrology indicates must be present.
Literature Review
We have reviewed the USGS Topographic Map, the Soil Survey of Guilford County and the Geologic
map of North Carolina to obtain information regazding the site.
• The USGS Topographic Map (Figure 1) shows Richland Creek located along the southern boundary
of the site. The map shows an unnamed tributary to Richland Creek crossing the southwestern
portion of the site. The map shows drainage swales on the site that could contain surface waters or
wetlands.
The USDA Soil Survey of Guilford County (Figure 2) shows the same streams as the USGS
Topographic Map. Soils on the site are mapped as Enon fine sandy loam (EnB, EnC and EnD), Enon
clay loam (EoC2), Wehadkee silt loam (Wh) and Willces sandy loam (WkC and WkE). The Enon
series consists of well drained, slowly permeable soils that occur on broad, smooth interstream
divides and long, narrow side slopes. The Wehadkee series consists of poorly drained, moderately
permeable soils that occur on stream floodplains. The Wilkes series consists of well drained,
moderately slowly permeable soils that occur on side slopes that generally border drainage ways.

ECS Carolinas, LLP Project G-13491

Wehadkee soils aze identified on the Hydric Soils List for Guilford County as being hydric or as
having hydric soils as a major component. The other soils on the site aze not identified on the Hydric
Soils List for Guilford County.
The Geologic Map of North Cazlina indicates that the site is located in the Carolina Slate Belt of the
Piedmont Physiographic Province. The soils encountered in this area are the residual product of in-
place chemical weathering of rock presently underlying the site. In general, shallow unconfined
groundwater movement within the overlying soils is controlled lazgely by topographic gradients.
Recharge occurs primarily by infiltration along higher elevations and typically dischazges into
streams or other surface water bodies. The elevation of the shallow water table is transient and can
vary greatly with seasonal fluctuations in precipitation. Movement in this water table is generally
from higher to lower elevations. As such, shallow groundwater on the site would be expected to flow
towazd Richland Creek located along the southern boundary of the site and its unnamed tributary that
crosses the southwestern portion of the site.
Site Reconnaissance
ECS personnel conducted the site reconnaissance on November 27, 2006. The site is an approximate
34.31 acre tract that is located on Old Jackson Lake Road in High Point, North Carolina. A portion of the
site is developed with a Lazco Asphalt Plant. The remainder of the site contains undeveloped, wooded
land and maintained sewer and powerline easements.
During our reconnaissance, we observed the site for evidence of stream channels, wetlands and ponds.
Richland Creek is located along the southern boundary of the site. Several streams are located on the site.
The streams have meanders, defined beds and banks in most azeas and contained flowing water at the
time of our site reconnaissance. The stream that crosses the southwestern portion of the site (depicted on
the USGS Topographic Map) and Richland Creek aze perennial, in our opinion. The other streams on the
site contained less flow at the time of our reconnaissance and are intermittent, in our opinion. Figure 3
shows the approximate locations of the streams, including our designations. The stream designations are
based on our opinion and should be used for preliminary planning purposes only. The designations aze
subject to change based on verifications by the U.S. Army Corps of Engineers (LTSACE) and the North
Cazolina Division of Water Quality.
Wetland hydrology indicators (including inundation and saturated soils), hydrophytic vegetation and
hydric soils were observed in pockets, adjacent to two of the streams. The wetland pockets are separated
from surrounding uplands by distinct topographic breaks, vegetation breaks and soil breaks. Upland areas
surrounding the wetland pockets aze vegetated primarily with honeysuckle, greenbrier, pines, cedars and
upland hardwood species. The soils aze bright and appeaz to be well drained to depths of at least twelve
inches. The centerlines of the streams and the wetland boundaries were flagged in the field by ECS
personnel. Richland Creek is high banked along the southern boundary of the site. Based on
conversations with Mr. Eddie MacEldowney with Davis, Martin, Powell and Associates, the top of
Richland Creek's banks will be surveyed. Therefore, ECS did not hang flags along Richland Creek.
Figure 3 shows the approximate locations of the stream and wetlands located on the site. Routine
Wetland Determination Data Forms containing field observations at the locations identified on Figure 3
aze included as Attachments. Figure 3 is based on our field notes and should only be used for preliminary
planning purposes. A survey of the flags will show the exact locations and extent of the stream and
wetlands on the site.

Discussion
Section 404 of the clean Water Act regulates the discharge of dredge and fill materials into waters of the
United States (lakes, rivers, ponds, streams, etc.), including wetlands. Waters of the United States include
the territorial seas, navigable coastal and inland lakes, rivers and streams, intermittent streams, and
wetlands. Activities that could be regulated under Section 404 include the placement of fill for
construction of roadways; residential, commercial or industrial structures; and the construction of water
retention ponds along tributaries. The EPA and the U.S. Army Corps of Engineers jointly administer the
Section 404 pmgram. Section 401 of the Clean Water Act grants each state the authority to approve,
condition, or deny any Federal permits that could result in a dischazge to State waters.
The streams and wetlands located on the site aze regulated by the U.S. army Corps of Engineers and the
North Carolina Division of Water Quality. We recommend that the delineated boundaries by verified by
the U.S. Army Corps of Engineers. A metes and bounds survey of the jurisdictional boundaries should be
conducted after the USACE verification to determine their exact locations and extent. Upon completion,
a copy of the wetland/stream survey map should be submitted to the U.S. Army Corps of Engineers for
final approval. A site/grading plan can then be developed to determine the extent of the proposed impacts
to jurisdictional waters and wetlands, if any. An attempt should be made to minim;~.e or avoid working in
these areas, if possible.
Permits will be required prior to impacting 1/10 acre or more of wetlands or any open waters, including
perennial or intermittent streams. Mitigation and stormwater management plans may be a condition of
any permits issued for the site. In addition, buffers maybe required adjacent to the stream and wetlands.
For impacts to one-half acre or more of wetlands or to more than 300 lineaz feet of stream channel, an
individual permit (lP) maybe required. An IP requires a habitat analysis, alternative site analysis, project
justification, plans to avoid and minimize impacts, and a proposed mitigation plan. Depending on the
habitat analysis and the extent of impacts, and Environmental Impact Statement may be required by the
U.S. Army Corps of Engineers. An ]P allows for a public comment period and may require 4 to 18
months to obtain depending on conditions arising during the U.S. army Corps of Engineers review and
public comment period.
ECS appreciates the opportunity to provide wetland services for your project. Please contact us at (336)
856-7150 if you have any questions concerning this report.
Sincerely,
ECS Ca1tOLnvas, LLP
