Dear Mr.Gardner:
Pilot Environmental, Inc. (Pilot)is pleased to submit this report of the wetland determination for
the approximate 4.16-acre tract located west of Harold Andrews Road in Siler City,Chatham
County, North Carolina.
Background
Wetlands are defined by the United S tates Army Corps of Engineers (USACE) and the United
States Environmental Protection Agency (EPA) as “those areas that are inundated or saturated
by surface or groundwater at a frequency and duration sufficient to support, and under normal
circumstances, do sup port 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 indicators must be present.
Section 404 of the Clean Wa ter Act (CWA)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, ri vers and
streams, intermittent streams, and wetlands. The EPA and the USACE jointly administer the
Section 404 program.Section 401 of the Clean Water Act grants each state the authority to
approve, condition, or deny any Federal permits that could resul t in a discharge to State waters.
Jurisdictional features include wetlands, open waters, ponds, lakes and perennial/intermittent
streams. Jurisdictional features are regulated by the USACE and North Carolina Department of
Environmental Quality-Division of Water Resources (NCDEQ-DWR). Permits are required prior to
impacting any jurisdictional feature . The type of permit required is specific to the type, location
and amount of impacts. Stormwater management plans and/or mitigation for proposed impacts
could be a requirement of the permit approval process.

The findings and conclusions in this report are our opinions based on field conditions
encountered at the time of the site visit. Changes including, but not limited to, regulations,
weather, timber/vegetation removal and usage/development of the site or nearby properties
can alter the findings and opinions presented in this report. We recommend that this report only
be used for preliminary planning purposes.A wetland delineation, followed by agency
verifications and a survey of jurisdictional features are required to determine the exact extent
and locations of jurisdictional features and are valid for a period of up to five years following
issuance of a USACE Jurisdictional Determination (JD) and/or NCDEQ-DWR Site Determination
Letter.
Scope of Services
Pilot was contracted to perform a wetland determination for the approximate 4.16-acre tract
located west of Harold Andrews Road in Siler City,Chatham County, North Carolina.The site
includes portions of the parcels identified by the Chatham County Geographical Information
System (GIS)as Parcel Identification Numbers (PINs)0066749 and 0061149.The scope of services
included a determination of jurisdictional features (streams, wetlands and other surface waters)
on the site.The site boundary was not marked at the time of our field determination.Pilot was
provided with a CAD file that included the site evaluation boundary which was identified as the limits
of disturbance.
Literature Review
We reviewed the U.S. Geological Survey (USGS) Topographic Map, the U.S. Department of
Agriculture (USDA) Soil Survey of Chatham County, the U.S. Fish and Wildlife Service (USFWS)
National Wetland Inventory (NWI)Map and the Federal Emergency Management Agency (FEMA)
Flood Insurance Rate Map (FIRM).
The USGS Topographic Map (Drawing 1)does not depict surface waters or wetlands on the site.
An unnamed tributary to the Rocky River is located approximately 250 feet northwest of the
site.
The USDA Web Soil Survey of Chatham County (Drawing 2) identifies the following mapping
units on the site:Cid-Lignum complex (CmB)and Nanford-Badin complex (NaB).The Badin series
consists of well drained, moderately permeable soils that occur on gently sloping to steep
uplands. The Cid series consists of moderately well drained to somewhat poorly drained, slowly
permeable soils that occur undulating to gently sloping interstream divides, on lower side slopes,
or on broad flats around the heads of drainageways on the uplands. The Lignum series consists
of moderately well drained to somewhat poorly drained, very slowly permeable soils that occur
in depressions, undulating uplands, interstream divides and around the heads of drainage ways.
The Nanford series consists of well drained, moderately permeable soils that occur on nearly
level to steep uplands.The CmB soil mapping unit is identified on the Chatham County Hydric
Soils List. The NaB soil mapping unit is not identified on the Chatham County Hydric Soils List.

Pilot also reviewed the last published USDA Soil Survey of Chatham County (Drawing 2A).The
published soil map does not depict surface waters or wetlands on the site.
The USFWS NWI Map (Drawing 3)does not depict surface waters or wetlands on the site. A
stream is depicted northwest of the site,generally consistent with the stream depicted on the
USGS Topographic Map.
Pilot reviewed the FEMA FIRM (Drawing 4)for the site.The FEMA FIRM identifies the site in an
area designated as Zone X,an area outside the 100-year and 500-year flood zones.
Field Determination
Pilot conducted the site visit on December 3,2019.The site contains undeveloped,wooded land
a gravel drive and grassed lawn.Ponds, streams and wetlands are not located on the site.The
site contains bright soils that appear to be well drained. A USACE Wetland Determination Data
Sheet was completed at the lowest point of the site and most probable to contain wetlands.
Neither wetland hydrology nor hydric soil indicators were observed. The data point location is
shown on Drawing 5 and is included as an attachment.
Watershed Classification
According to the NCDEQ-DWR, the site is located in the Cape Fear River Basin.An unnamed tributary
to the Rocky River is located approximately 250 feet northwest of the site.The NCDEQ-DWR has
classified the Rocky River, the receiving waters,as Class C waters.Site development is not subject
to state regulated riparian buffers.Consultation with the local planning authority is recommended
to determine applicability to stormwater and/or local surface water buffer requirements.
Summary
Pilot has completed a stream/wetland determination at the site.No streams, ponds or wetlands
were identified during the determination. The determination has not been verified by the USACE
or the NCDEQ-DWR.
