Dear Mr. Brack:
ECS Southeast, LLP (ECS) is pleased to submit this preliminary report of wetland delineation
report for the above-referenced site. This report summarizes our findings and recommendations
for the site.
Background
The project study area (PSA) is located off of Moore Drive in, Durham County, North Carolina
(Figure 1). The project study area consists of portions of seven parcels. According to the
Durham County NC GIS Database website, the Parcel Identification Numbers (PINs) are 0739-
74-19-8533, 0739-85-90-8453, 0739-86-65-3511.SRV, 0739-02-77-4055, 0739-02-98-2166,
0739-86-65-511.RTP, and 0749-06-62-8419. The project study area consists of approximately
300 acres and is owned by Parmer RTP, LLC. It primarily contains undeveloped, heavily
wooded land with some commercial buildings throughout. According to the United States
Geological Survey (USGS) Topographic Map, two unnamed tributaries are depicted flowing east
to west down to Northeast Creek that flows along the western boundary (Figure 2).
Wetlands are defined by the U.S. 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 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 indicators must be present described in the 1987 “Corps of Engineers
Wetlands Delineation Manual” and the appropriate Regional Supplement.
Literature Review
ECS reviewed the USGS Topographic Map, the United States Department of Agriculture
(USDA) Natural Resources Conservation Service (NRCS) Soil Survey for Durham County, the
U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) Map, the Federal
Emergency Management Agency (FEMA) National Flood Hazard Layer (NFHL), the National
Hydric Soils list for Durham County, and the Geologic Map of North Carolina to obtain
information regarding the PSA.

The USGS Topographic Map, Durham, NC Quadrangle, depicts two unnamed tributaries
flowing east to west down to Northeast Creek that flows along the western boundary (Figure
2).
The USDA-NRCS Soil Survey of Durham County depicts three surface waters on site
(Figure 3). Soils on site have been mapped as Altavista Silt Loam, Cartecay and Chewacla
soils, CHewacla and Wehadkee soils, Congaree Silt Loam, Creedmoor Sandy Loam,
Mayodan Sandy Loam, Pinkston Fine Sandy Loam, White Store Sandy Loam, White Store
Clay Loam, and Urban Land. The Pinkston Fine Sandy Loam and Mayodan Sandy Loam
are well drained, whereas the Altavista Silt Loam, Congaree Silt Loam, Creedmoor Sandy
Loam, White Store Sandy Loam, and the White Store Clay loam are moderately well
drained. The Cartecay and Chewacla Soils and Chewacla and Wehadkee soils are
somewhat poorly drained. Of these soils, the Altavista Silt Loam, Cartecay and Chewacla
soils, CHewacla and Wehadkee soils, and Congaree Silt Loam, appear on the National
Hydric Soils list for Durham County, North Carolina.
ECS reviewed the USFWS NWI Map of the PSA (Figure 4). The map depicts two riverine
wetlands (R4SBC) (R5UBH), two freshwater forested/shrub wetlands (PF01A) (PSS1A), and
two freshwater ponds (PUBHh) within the PSA.
ECS reviewed the FEMA NFHL dataset. The site is depicted on FEMA FIRM Panel
37063C_761, dated February 20, 2018 (Figure 5). The map indicates the site is located
primarily on Zone X. Zone X is defined as areas determined to be outside the 0.2% annual
chance floodplain. The site is prone to flooding along the western boundary of the site, as
well as up along the big stream that bisects the site from east to west. Here it is depicted to
be on zone AE. Zone AE is defined as areas where an area inundated by 1% annual chance
flooding, for which base flood elevations (BFEs) have been determined.
The Geologic Map of North Carolina indicates that the site is located in the Piedmont
Physiographic Province. The soils encountered in this area are the residual product of in-
place chemical weathering of rock presently underlying the PSA. In general, shallow
unconfined groundwater movement within the overlying soils is controlled largely by
topographic gradients. Recharge occurs primarily by infiltration along higher elevations and
typically discharges 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 would be expected to flow beneath the PSA to unnamed tributaries and
eventually to the Cape Fear River.
Site Reconnaissance
ECS conducted the site reconnaissance on September 16-17th and October 7th, 2019. During
the reconnaissance, the site was observed for evidence of ponds, tributaries, and wetlands.
Nine potential tributaries, three potential wetlands, one marginal area, and two ponds were
observed during the site reconnaissance.
Figure 6 depicts the site boundary and feature locations on site and should be used for
preliminary planning purposes. The features depicted have not been verified by the USACE or
NCDWR and are subject to change.

USACE & NCDWR Field Verification and Jurisdictional Determination
After review of the findings in the report and at the client’s request, ECS can coordinate with the
USACE and NCDWR to conduct a field verification and subsequent jurisdictional determ ination.
ECS will forward the correspondence upon receipt.
General 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 which are normally 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 USCAE 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
result in a discharge to State waters.
Streams, ponds, and wetlands are regulated by the USACE and the North Carolina Department
of Water Resources (NCDWR). Permits are required prior to impacting wetlands or open
waters, including ponds, lakes, and perennial or intermittent streams. Mitigation and stormwater
management plans will be a condition of permits issued for the site. Buffers may be required
adjacent to streams and water bodies.
For impacts to one-half acre or more of wetlands/waters or to 300 linear feet or more of
perennial stream channel, an individual permit (IP) may be 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 USACE. An
IP allows for a public comment period and may require 4 to 18 months to obtain depending on
conditions arising during the USACE review and public comment period.
Watershed Classification/Buffer Requirements
State Riparian Buffer Requirements
The PSA is located in the Cape Fear River Basin within the Jordan Lake W atershed. Surface
waters within the Cape Fear River Basin above the Jordan Lake watershed are subject to
mandatory 50 foot riparian buffers.
Local Buffer Requirements
ECS reviewed the Durham County Code of Ordinances to determine if the county has
vegetative buffer requirements for surface waters. According to the Ordinance, a minimum one
hundred-foot vegetative buffer is required for all new development activities that exceed the low
density option; otherwise, a minimum fifty-foot vegetative buffer for development activities is

required along all perennial waters indicated on the most recent versions of U.S.G.S. 1:24,000
(7.5 minute) scale topographic maps or as determined by local government studies. Desirable
artificial streambank or shoreline stabilization is permitted.
Stormwater Requirements
Surface waters located within the PSA appear to flow towards Northeast Creek and eventually
to the Cape Fear River which is classified as Class C. Class C waters are protected for uses
such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including
propagation, survival and maintenance of biological integrity, and agriculture. Secondary
recreation includes wading, boating, and other uses involving human body contact with water
where such activities take place in an infrequent, unorganized, or incidental manner. ECS
reviewed the NCDWR online stormwater permitting map to determine jurisdiction of NCDWR
stormwater regulations. According to the online permitting map, it appears the site is located in
an area designated as Local Permitting Authority. ECS recommends consultation with a civil
engineer to determine if mandatory vegetative buffers and/or regulated development
(impervious surfaces) setbacks are required for the site in addition to those mentioned above.
