EXECUTIVE SUMMARY
Sage Ecological Services, Inc. (Sage) was retained by Mr. Steven Fuhrman to complete an
evaluation of wetlands, streams and riparian buffers on the approximately 1.39-acre parcel (Site)
located at 3421 Donnigale Avenue in SW Durham, North Carolina. Property identification number
(PIN) 0801-60-85-9056 corresponds to the Site. The purpose of this evaluation was to determine if
jurisdictional waters (e.g. wetlands, streams, ponds, etc.) and/or their associated riparian buffers
exist on the Site and if so to approximate their limits. Mr. Sean Clark and Mr. Phil Beach, PWS of
Sage completed the field evaluation on June 25, 2019. The attached Figure 1 shows the general
location of the Site on the applicable SW Durham, INC United States Geological Survey (USGS)
topographical quadrangle sheet, and Figure 2 shows the Site's location on the applicable portion
(sheet 25) of the United States Department of Agriculture's Natural Resources Conservation
Service (USDA NRCS) Soil Survey for Durham.
One marginal stream (SA) was identified and flagged on the Site. Portions of SA were found to be
both potentially buffered, and jurisdictional. No wetlands were found to be located on the site.
The attached Figure 3 shows the approximate location and limits of SA. Field meetings with the US
Army Corps of Engineers (USACE) and the City of Durham will be required to verify the limits of the
stream / wetland delineation and riparian buffer determination performed by Sage. Any features
determined to be jurisdictional should be located by a licensed surveyor in order to produce a
survey for the approval as well as for final planning purposes.
SECTION 1
REGULATION DEFINITION
1.1 Definition of "Waters of the United States"
"Waters of the United States" is a broad term originally defined within the Clean Water Act of 1972,
which includes intrastate lakes, rivers, perennial and intermittent streams, mudflats and sand flats,
wetlands, sloughs, wet meadows, and ponds, which could affect interstate and foreign
commerce.
1.2 Definition of Wetlands
Within the 1987 USACE Wetlands Delineation Manual (Environmental Laboratory, 1987) wetlands
are defined as follows:
Wetlands are "those areas that are inundated or saturated by surface or
ground water at a frequency and duration sufficient to support, and that under
normal circumstances do support, a prevalence of vegetation typically
adapted for life in saturated soil conditions. Wetlands generally include
swamps, marshes, bogs, and similar areas."
Three parameters are used to determine if an area is classifiable as a wetland. These three criteria
are hydric soils, hydrology, and vegetation. Positive indicators of all three parameters must be
found in order for the area to be considered a wetland.
1. Soils: As currently defined by the USACE, some indicators of hydric soils include a chroma
value of 2 or less (i.e. grayish color) in the Munsell Soil Color Chart or a gleyed color, the
presence of a sulfidic odor, a high organic content in surface layer of sandy soils,
concretions (e.g. manganese), or the listing of the soil series on the national or local hydric
soils list.
2. Hydrology: Primary indicators of wetland hydrology include the presence of free water in
an excavated pit or saturated soils within the upper twelve inches of the soil, standing
water or inundated conditions, sediment deposits, water stained leaves, or oxidized root
channels in the upper twelve inches of the soil. Secondary indicators include, but are not
limited to, crayfish burrows and drainage patterns. Only one primary hydrology indicator
is required in order for an area to contain wetland hydrology, however, two secondary
indicators are required if there is no primary indicator present.
2
3. Vegetation: Vegetation commonly found in and adjacent to wetlands are rated based
on the percentage of time that each species is found in a wetland or on high ground that
is not wetland. Species found almost exclusively in wetlands (99% or more) are considered
obligate wetland species (OBL). Species found 67% to 98% of the time in wetlands, are
considered facultative wetland (FACW) species and species found in wetlands 34%to 66%
of the time are considered facultative species (FAC). Facultative Upland Species (FACU)
and Obligate Upland Species (UPL) refer to those species that occur predominately in
upland, or non -wetland areas. In order for an evaluated area to meet the hydrophytic
vegetation requirement, 50% or greater of the dominant plant species must be FAC or
wetter.
1.3 Definition of Streams
In general, there are three main stream types that describe overall stream flow. These are
ephemeral, intermittent, and perennial. Ephemeral streams only contain water immediately after
a large rain event whereas perennial stream channels typically contain water throughout the
year. Intermittent streams may contain water during the winter (i.e. during higher water table
periods of time) but are usually dry during the summer except after rain events. Streams are
assessed and defined locally by the USACE and the NC Division of Water Resources (NCDWR).
Each agency has its own assessment form and methodology that is used to describe and define
streams. Both forms assign numerical values to different stream characteristics which generally
break into the three main categories of Geomorphology, Hydrology, and Biology. The NCDWR
currently uses the "NC DWQ Stream Identification Form Version 4.11 " and the USACE currently uses
the "Stream Quality Assessment Worksheet." NCDWR's form is also utilized to determine the
applicability of riparian buffers on intermittent and perennial streams within the river basins where
stream buffers are applied. Currently, ephemeral streams are not buffered by the NCDWR.
1.4 Regulation of Wetlands and Streams
Wetlands and streams are USACE regulated "waters of the United States" under Section 404 of
the Clean Water Act. Section 404, administered by USACE, requires permits for discharges of
dredged or fill material into regulated "waters of the United States." As granted under Section 401
of the Clean Water Act, the state of North Carolina, through the NCDWR, also regulates
disturbance activities in wetlands or other waters of the United States in the state of North Carolina.
3
NCDWR also regulates disturbance activities within wetland and stream areas that are "isolated"
from waters of the US and are therefore not regulated by the USACE due to their lack of
connection to other waters of the US. All areas regulated by NCDWR are considered "waters of
the state" and disturbance to these areas are permitted through the 401-permitting process which
is separate from the USACE's 404-permitting process.
1.5 Regulation of Riparian Buffers
Within the Jordan Lake drainage, the NCDWR regulates a 50-foot riparian buffer that extends
landward from each side of surface waters (e.g. streams, lakes, ponds, rivers, etc.). The City of
Durham regulates activities within the 50-foot buffer when these areas are within the city's
jurisdiction. Drainage features depicted as streams on the most recently published USGS
topographical maps and/or the most recently published NRCS soil survey maps are subject to
these buffers unless determined otherwise by City of Durham staff. A cumulative score of 19 on
the previously mentioned "NC-DWQ Stream Identification Form Version 4.11 " is required in order
for the stream to be subject to the rules. A score of less than 19 typically means that the stream is
ephemeral and is therefore not subject to the 50-foot buffers. Activities within the buffers fall into
the four main categories of exempt, allowable, allowable with mitigation, and prohibited. All
activities within the buffers except for those determined to be exempt require prior written
approval.

SECTION 2
SITE DESCRIPTION
2.1 Site Location
The Site is located approximately 300 feet east of the Brecknock Street and Donnigale Avenue
intersection in Durham, North Carolina. The coordinates of 35.977055°N, 78.976750°W, generally
correspond to the center of the Site. The Site is within the piedmont region of North Carolina and
is within the Cape Fear River Basin.
2.2 General Site Description
The 1.39 -acre Site is wooded and undeveloped. A canopy of mixed hardwoods, open understory
and dense herb layer are present on the Site. The property generally slopes from NE to SW.
Soils on the Site are mapped in the Durham County Soil Survey to contain the White Store sandy
loam soil series. The topography of the Site ranges from a low point of +/- 300 feet above mean
sea level (msl) at the northeastern property corner to a high point of 326 feet msl in in the SW
corner of the Site.

SECTION 3
SCOPE OF SERVICES
3.1 Performed Scope of Work
Sage was contracted to complete an evaluation of wetlands, streams, and riparian buffers on the
Site. The methodology for our work is discussed below.
3.2 Wetland Evaluation Methodology
The wetland evaluation was completed based upon the procedures specified and described in
the "Corps of Engineers Wetlands Delineation Manual" (January 1987 - Final Report) and using
the current regional guidance. Prior to arriving on -site, topographical maps, soil survey maps,
orthophotographs, and ArcGIS generated maps of the area were reviewed to preliminarily
identify areas (e.g. drainages, hydric soils areas, areas showing standing water, etc.) where
wetlands would likely exist. The Site was traversed on foot and evaluated for the presence of hydric
soils indicators, evidence of wetland hydrology, and existence of hydrophytic vegetation.
3.3 Stream and Riparian Buffer Evaluation Methodology
Topographical maps, soil survey maps, and aerial maps of the Site were reviewed in order to
preliminarily identify drainages where potential streams may exist. It is important to note that the
NRCS web -based soil maps do not indicate drainages and streams. Drainages within the Site were
evaluated using the current "NC-DWQ Stream Identification Form (Version 4.1 1)" and/or the
USACE's Stream Quality Assessment Worksheet. Both agencies have their own forms, which assign
numerical values to different characteristics such as the presence of fish, particle size in the stream
versus that of the adjacent upland area, etc. NCDWR's form is used to identify if a drainage is
subject to riparian buffers as well as to identify the stream's flow regime (i.e. ephemeral,
intermittent, or perennial).
The USACE's form does not attempt to define a stream as being intermittent or perennial. The
NCDWR's terms and the USACE's terms are not always synonymous and interchangeable. The
USACE generally considers a drainage to contain a jurisdictional stream if there is an Ordinary High
Water Mark (OHWM) or evidence of periodic concentrated flow. The stream designations from
both the USACE and DWR hold more significance in the event that impacts (e.g. road or utility
N.
crossings or general fill) are required. The NCDWR will require mitigation for impacts to intermittent
and perennial streams. The USACE typically requires mitigation for impacts to streams that are
"important to aquatic function" and may not require mitigation for impacts to streams that are
not as much so.

SECTION 4
RESULTS OF EVALUATION
4.1 Wetlands Evaluation
The Site was evaluated per the methodology described above for any areas containing the three
wetland criteria (hydric soils, wetland hydrology, and hydrophytic vegetation). No areas which
met the three parameter criteria were identified on the Site.
4.2 Stream Determinations
Stream forms were completed in several locations along Features SA and SB. These were
completed in order to determine if any areas met the stream criteria described above in Section
3.3. Stream form locations were flagged in the field and labeled to correspond with the forms
attached to this report. Stream Form SFA3 on feature SA scored a 20.5 on the NCDWQ Stream
Identification Form within the flagged section between flag SA01 and SA02. This section of SA
exhibited a weak presence of differentiated substrate, absent depositional bars / benches, and
weak headcuts. The remaining portions of the evaluated SA drainage scored a 4.5 (stream form
SFA4) above flag SA01 and a 15.5 and 16.5 at areas down slope from flag SA02.
Feature SB, which is not depicted on the USGS or soil survey maps, scored a 16.5 at the top of the
evaluated drainage and a 15.75 at a point down slope. This drainage did not exhibit baseflow,
contained weak sinuosity, and had poor substrate differentiation. Furthermore, no hydric soils were
observed within the drainage. Upon completion of the field assessment it was determined that
Feature SA is marginally intermittent, and Feature SB is ephemeral. The table below and Figure 3
provide additional information and a visual description for the feature located on the tract.

The Site ultimately drains to Mud Creek which is classified as a Water Supply V (WS-V; NSW). These
classifications are generated by the NC DEQ's "Classifications and Water Quality Standards
0
Applicable to Surface Water and Wetlands of North Carolina." Please note that the jurisdictional
status of site drainages needs to be confirmed by the USACE to be valid.
4.3 Riparian Buffer Determinations
Stream Feature SA is approximately located on the Soil Survey for Durham County and also
exhibited intermittent flow with a score >19 on the NC-DWQ 4.11 within the section between flags
SA01 and SA02. Therefore, SA is potentially subject to the NCDWR regulated Jordan Buffer Rules.
The drainage above flag SA01 and below flag SA02 is believed to be ephemeral and not subject
to the riparian buffers.
Feature SB is not depicted on either Soil Survey nor most recent USGS map for Durham County,
and also did not exhibit indications of intermittent flow. Therefore, SB is not subject to the NCDWR
regulated Jordan Buffer Rules. SA is believed to begin at flag SAO1 which is located in the northern
portion of the Site. As previously mentioned, a field determination by Durham staff or NCDWR will
be necessary to verify our buffer determinations.

SECTION 5
CONCLUSIONS AND RECOMMENDATIONS
5.1 Conclusions and Recommendations
The wetland, stream, and riparian buffer evaluation was completed for the 1.39-acre Site on June
25, 2019. Upon completion of the field investigation, map assessment, and literature review, it was
determined that a section of marginal potentially jurisdictional and buffered, intermittent stream
starts in the northern portion of the property approximately 40 feet west of the eastern property
line and flows for +/- 100 feet. Another drainage feature was identified in the field (SB) and
determined to not be jurisdictional or subject to riparian buffers.
A site meeting with the USACE is recommended prior to the development of the Site in order to
confirm the jurisdictional status of Features SA and SB as well as to concur that no wetlands are
present on the Site. The field verification may be required in order to obtain a preliminary
jurisdictional determination (PJD). It is also recommended that a buffer determination with the City
of Durham (NCDWR delegated authority) be conducted to verify our findings as they relate to the
subjectivity of riparian buffers on the Site.
If development is proposed on the Site, a state buffer authorization, federal permit (for stream
impacts), and state water quality certification may be required to develop this Site. Sage is
available to assist with preparing the aforementioned documents for submittal and/or to conduct
or coordinate any required additional surveys in conjunction with permit. Features determined to
be jurisdictional and / or subject to buffers should be located by a licensed surveyor in order to
produce a survey for the approval as well as for final planning purposes.
