Salt Barn Tributary Regenerative Stormwater Conveyance
Greensboro, North Carolina
Dear Mr. Bailey and Ms. Higgins:
On behalf of our client, City of Greensboro (COG), HDR Engineering, Inc. of the Carolinas (HDR), is
requesting written authorization under a Nationwide Permit (NWP) 18 (Minor Discharge) for activities
associated with the Salt Barn Tributary Regenerative Stormwater Conveyance (RSC) project in
Guilford County, North Carolina (Figure 1 and Figure 2).
The proposed Salt Barn Tributary Regenerative Stormwater Conveyance Project is located adjacent
to 2252 Randolph Avenue in Greensboro, North Carolina. The project is located in the Haw River
subbasin in the Cape Fear watershed (U.S. Geological Survey [USGS] Hydrologic Unit Code [HUC]
0303002). This project is also within the Jordan Lake Nutrient Sensitive Waters watershed. The
purpose of this project is to stabilize a degraded channel draining from an existing settling basin
adjacent to a City of Greensboro salt storage facility. The proposed project will also provide a
reduction in pollutant load from the drainage area that flows to a tributary to Mile Run Creek.
Applicant Name: City of Greensboro: POC: Mr. Steven Drew. Director of Water Resources

According to the Soils Survey of Guilford County (NRCS 2016). on-site soils consist of Chewacla
loam, 0 to 2 percent slopes, frequently flooded (ChA) and Enon-Urban land complex. 2 to 10 percent
slopes (EuB) (Figure 4). Chewacla loam (ChA) soils appear on the National Hydric Soils List for
Guilford County and are classified as somewhat poorly drained soils with hydric inclusions typically
found in depressions in floodplains along streams and drainageways.
The U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) provides U.S.
wetlands data and analyses tools, which are available to the public (USFWS 2017). The USFWS NWI
does not depict any features within the Project Area (Figure 5). The U.S. Geological Survey (USGS)
National Hydrography Dataset (NHD) provides publicly available digital geospatial datasets that
present maps of surface water networks and watersheds of the U.S. (USGS 2017). The USGS NHD
does not depict any streams within the Project Area (Figure 5). The northeast corner of the Project
Area is located within a Federal Emergency Management Act (FEMA) floodplain (FEMA FIRM Panel
3710786300J) (Figure 5) (FEMA 2017).
Jurisdictional Determination
On January 10, 2017, HDR environmental scientists reviewed the Project Area for waters of the U.S.
under Section 404/401 of the Clean Water Act (CWA). Jurisdictional waters of the U.S. were
delineated according to the methodology and guidance described in the U.S. Army Corps of
Engineers (USACE) 1987 Wetland Delineation Manual (USACE 1985), USACE Post-Rapanos
guidance, and the 2012 USACE Eastern Mountains and Piedmont Regional Supplement (USACE
2012, Version 2.0). Streams were classified utilizing the methodology and guidance provided in
Regulatory Guidance Letter (RGL) 05-05 (USACE 2005) and the North Carolina Division of Water
Quality (NCDWQ) Methodology for Identification of Intermittent and Perennial Streams and Their
Origins (NCDWQ 2010, Version 4.11). Jurisdictional waters of the U.S. were flagged in the field and
mapped using a Trimble" Geo7X GPS unit capable of sub -meter accuracy. GPS points were post -
processed utilizing Trimble'- GPS Pathfinder Office software.
Results
The results of the wetland delineation conducted by HDR indicate that there is one jurisdictional
stream channel (Stream 1) within the Project Area, which is an unnamed tributary (UT) to Mile Run
Creek (Figure 6). Mile Run Creek is within the Cape Fear River Basin (HU# 03030002) and is
classified as "Water Supply V (WS -V)" and "Nutrient Sensitive Waters (NSW)" waters by the North
Carolina Division of Water Resources (NCDWR). According to the NCDWR, WS -V waters are defined
as, "waters protected as water supplies which are generally upstream and draining to Class WS -IV
waters or waters used by industry to supply their employees with drinking water or was waters
formerly used as water supply." Nutrient Sensitive Waters are defined as "waters subject to growths of
microscopic or macroscopic vegetation requiring limitation on nutrient inputs" (NCDWR 2017).
Jurisdictional Features
On-site jurisdictional waters of the U.S. total approximately 249 linear feet (If) of jurisdictional stream
channel. No jurisdictional wetlands are located within the project limits. A summary of on-site
jurisdictional waters is provided in Table 1.

Creek (Figure 5). Stream 1 (R4SB4 [Cowardian et at. 1979]) exhibits strong continuity of bed and
bank, moderate particle size of stream substrate, and moderate presence of baseflow, The Ordinary
High Water Mark (OHWM) was observed at approximately 4 inches above the bed of the channel.
Biological sampling did not reveal any aquatic organisms located within the channel. Photographs of
Stream 1 are attached.
Agency Correspondence
Cultural Resources
A letter was forwarded to the N.0 State Historic Preservation Office (SHPO) on February 1, 2017 to
determine the presence of any areas of architectural, historic, or archaeological significance that
would be affected by the project. HDR also consulted the SHPO online GIS service' and the
Greensboro Historic Preservation Commission (HPS)2 database and found no sites of architectural,
historical, or archaeological significance within the project limits. A response from SHPO was received
on February 17, 2017, concurring with the findings above (ER 17-0228, attached).
Protected Species
HDR performed a data review using the North Carolina Natural Heritage Program (NCNHP) Data
Expiorer3 on February 1, 2017 to determine the presence of any federally -listed, candidate
endangered, threatened species or critical habitat located within the project area. Based on this
review, there are no records of federally -protected species within the project limits. A copy of the data
review report is attached.
HDR obtained and reviewed a list of federally protected species for Guilford County from the USFWS
website, which was last updated on March 25, 2015. A summary of these species is provided in Table

Current = The species has been observed in the county within the last 50 years.
HDR conducted an on-site visit and determined that the project site does not exhibit habitat for bald
eagle or small whorled pogonia. Vegetation within the project site was dominated by non-native
invasive species including fescue (Festuca sp.).. multiflora rose (Rosa multiflora). sawtooth blackberry
(Rubus argutus), and Japanese honeysuckle (Lonicera japonica).
A field review of the project site indicated that no suitable summer roosting habitat for the NLEB is
present within the Limits of Disturbance. No individuals of the NLEB were observed.
According to the NCNHP data report (NCNHDE-2880. attached). no federally protected species occur
within one mile of the proposed project area. As a result, the proposed project is not anticipated to
impact any federally protected species or Critical Habitat.
Purpose and Need for the Project
The Salt Barn Tributary is an unnamed tributary to Mile Run Creek that handles runoff from a highly
impervious area that includes a salt barn facility and parking area owned by the City of Greensboro.
The location has been identified as having the potential to provide water quality benefits through the
use of an oil/water separator in combination with a regenerative stormwater conveyance (RSC) to
reduce the nutrient loading from the drainage area.
The outfall channel is experiencing extreme headcutting due to "flashy" stormwater runoff. Moreover,
the existing settling basin and outfall channel directly discharges runoff from a city -owned salt barn
facility to downstream jurisdictional waters. This project will not only stabilize the existing outfall
channel, but also provides an opportunity to increase the water quality draining to Mile Run Creek.
The project includes an existing 24 -inch pipe which discharges to the existing settling basin and outfall
channel. This pipe will be cut upstream of the outfall where a diversion box will be constructed to
divert low -flow runoff into an oil/water separator. The oil/water separator will intercept any oil spills that
occur during dry conditions, providing additional water quality protection. A flow splitter will be
installed in the diversion box to ensure runoff in excess of the oil/water separator's capacity does not
enter the oil/water separator. The RSC will provide safe conveyance for up to, and including the 100 -
year runoff, and will provide water quality pollutant reduction for runoff that is retained within the RSC
pools and filtered through RSC media.
The purpose of the project is to stabilize the degraded channel and provide water quality pollutant
reductions through the use of a RSC.
Avoidance and Minimization
Under the No -Build Alternative. the RSC would not be built. The outfall channel would continue to
degrade and headcut up to meet the outfall pipe from the settling basin. Additionally, no water quality
Page 14

Salt Barn Tributary Regenerative Stormwater Conveyance
Request for PJD. NWP 18 and WQC No. 4092
October 16. 2017
benefits would be realized without treatment design measures in the RSC. Therefore. the No -Build
Alternative was not chosen as the preferred design.
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent
possible. Proper sediment and erosion control measures will be used to minimize disturbances to
downstream waters. A pump around will be utilized to ensure that all work is conducted in the dry, as
applicable.
The project complies with all FEMA -approved state and/or local floodplain management requirements,.
including obtaining a Floodplain Development Permit from the City of Greensboro's Stormwater
Division.
Proposed Impacts to Jurisdictional Waters under NWP 18
The existing non -jurisdictional settling basin will be converted to an RSC utilizing a series of 12 rock
step -pool structures. The RSC will continue through the settling basin, through the non -jurisdictional
outfall channel, and will tie into the downstream jurisdictional channel. The RSC will accumulate runoff
that will infiltrate through the RSC media, filtering runoff pollutants prior to discharging to downstream
surface waters.
Impacts to Stream 1 resulting from the construction of the RSC in the existing stream channel will total
80 linear feet of permanent impacts, consisting of three rock step -pool structures. These 3 rock step -
pool structures are the last thee rock step -pools of the 12 rock step -pool RSC. A total of 2.96 cubic
yards of fill will be placed below the OWHM of Stream 1. These impacts to Stream 1 are necessary to
provide the appropriate length of the RSC, to stabilize the degraded channel, and to tie RSC to the
downstream channel at an acceptable slope.
The construction of the RSC will function to filter pollutants from the drainage area. Table 3, below,
summarizes the unavoidable impacts to on-site jurisdictional waters of the U.S.

The project proposes minimal earthwork. Any areas clearing during construction will be revegetated
with native seed and woody plants.
Buffer Impacts
According to the Jordan Water Supply Nutrient Strategies: Protection of Existing Riparian Buffers
(15A NCAC 02B .0267). the Jordan Lake buffer rules apply to "intermittent streams. perennial
streams, lakes, ponds and reservoirs that are depicted only on the following maps: the most recent
printed version of the soil survey map prepared by the Natural Resources Conservation Service OR
the 1. 24, scale quadrangle topographic map prepared by the U.S. Geologic Survey OR a map
approved by the Geographic Information Coordinating Council and by the N. C. Environmental
Management Commission."
Stream 1 is not depicted on any of the abovementioned reference data; therefore. this project is
exempt from the Jordan Water Supply Nutrient Buffers.

Jurisdictional Determination Request
F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One)
I am requesting that the Corps provide a preliminary JD for the property identified herein.
A Preliminary Jurisdictional Determination (PJD) provides an indication that there may
be "waters of the United States" or "navigable waters of the United States"on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional "waters of
the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is
"preliminary" in the sense that an approved JD can be requested at any time. PJDs do
not expire.
❑ I am requesting that the Corps provide an a2proved JD for the property identified herein.
An Approved Jurisdictional Determination (AJD) is a determination that
jurisdictional "waters of the United States" or "navigable waters of the United
States" are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner, permit applicant, or other "affected
party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).
❑ I am unclear as to which JD I would like to request and require additional information
to inform my decision.
G. ALL REQUESTS
aMap of Property or Project Area. This Map must clearly depict the boundaries of the
review area.
✓❑ Size of Property or Review Area 1.6 acres.
❑ The property boundary (or review area boundary) is clearly physically marked on the site.

I ) The Corps of Engineers believes that there may bejurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre- construction
notification" (PCN), or requests verification for a non -reporting NWP or other general permit,
and the permit applicant has not requested an AJD for the activity, the permit applicant is
hereby made aware that: ( I ) the permit applicant has elected to seek a permit authorization
based on a PJD, which does not make an official determination of jurisdictional aquatic
resources; (2) the applicant has the option to request an AJD before accepting the terms and
conditions of the permit authorization, and that basing a permit authorization on an AJD could
possibly result in less compensatory mitigation being required or different special conditions;
(3) the applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can accept
a permit authorization and thereby agree to comply with all the terms and conditions of that
permit, including whatever mitigation requirements the Corps has determined to be necessarv;
(5) undertaking any activity in reliance upon the subject permit authorization without
requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a
permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in
reliance on any form of Corps permit authorization based on a PJD constitutes agreement that
all aquatic resources in the review area affected in any way by that activity will be treated as
jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial
compliance or enforcement action, or in any administrative appeal or in any Federal court;
and (7) whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and
conditions contained therein), or individual permit denial can be administratively appealed
pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to
make an official determination whether geographic jurisdiction exists over aquatic resources
in the review area, or to provide an official delineation of jurisdictional aquatic resources in
the review area, the Corps will provide an AJD to accomplish that result, as soon as is
practicable. This PJD finds that there "mcry be" waters of the U.S. and/or that there "mm, be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic features in
the review area that could be affected by the proposed activity, based on the following
information:

3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Land use within the project limits consists of a parking lot and an adjacent wooded area. Immediately adjacent to the project limits is a City -owned
salt barn and parking area to the west and southwest and the Gillespie Golf Course fairway to the north. Mile Run Creek is located across the fairway
o the north and its floodplain extends into the project limits. An aerial photograph of the project limits is attached (Figure 3).
3b. List the total estimated acreage of all existing wetlands on the property: o
3c. List the total estimated linear feet of all existing streams intermittent andperennial) on the property: 249 linear feet
3d. Explain the purpose of the proposed project:
The purpose of this project is to stabilize an existing degraded channel draining an existing settling basin along a tributary to Mile Run Creek in
order to stabilize the existing channel. A secondary benefit of the project is to provide a reduction in pollutant load from the drainage area.
3e. Describe the overall project in detail, including the type of equipment to be used:
The Salt Barn Tributary is an unnamed tributary to Mile Run Creek that handles the runoff from a highly impervious area that includes a salt barn
and parking area owned by the City of Greensboro. The location has been identified as having the potential to provide water quality benefits through
the use of an oil/water separator in combination with a regenerative stormwater conveyance (RSC) to reduce the nutrient loading from the drainage
area.
The outfall channel is experiencing extreme headcutting due to "flashy' stormwater runoff. Moreover, the existing settling basin and outfall channel
directly discharges runoff from a city -owned salt barn facility to downstream jurisdictional waters. This project will not only stabilize the existing
outfall channel, but also provides an opportunity to increase the water quality draining to Mile Run Creek.
The project includes an existing 24 -inch pipe which discharges to the existing settling basin and outfall channel. This pipe will be cut upstream of the
outfall where a diversion box will be constructed to divert low -flow runoff into an oil/water separator. The oil/water separator will intercept any oil
spills that occur during dry conditions, providing additional water quality protection. A flow splitter will be installed in the diversion box to ensure
runoff in excess of the oil/water separator's capacity does not enter the oilAvater separator. The RSC will provide safe conveyance for up to, and
including the too -year runoff, and will provide water quality pollutant reduction for runoff that is retained within the RSC pools.
The purpose of the project is to stabilize the degraded channel and provide water quality pollutant reductions through the use of a RSC.
Typical construction equipment such as track hoes and excavators will he used during construction.

NCNHDE-2880
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, or conservation/managed areas within the proposed project boundary. These
results are presented in the attached 'Documented Occurrences' tables and map.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists and is
included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the
project area, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund
(CWMTF) easement, or an occurrence of a Federally -listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
contact Matthew Hebb at matthew.hebbCcDncdcr.aov or 919.707.8603.
Sincerely,
NC Natural Heritage Program

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that although the NCNHP database
does not show records for rare species within the project area, it does not necessarily mean that they are not present; it may simply mean that the area has not been surveyed. The
use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project area contains suitable habitat for rare species. If rare
species are found, the NCNHP would appreciate receiving this information so that we may update our database.
