ORV,,jAfiI BRANCH
On behalf of Patrick E. Carlton, Trustee, we are applying for a General
Certification 3705 for impacts to waters of the U.S to facilitate the construction
of an irrigation supply system within Robinson Creek for water withdrawal
purposes. Withdrawal from Robinson Creek will be used to supplement and
maintain pool level in Tulip Pond during abnormally dry periods or drought
conditions. Tulip Pond is the existing reservoir for the property's irrigation
supply.
The project site is located within Robinson Creek, approximately 0.10 mile
northwest of Breedlove Road and 3 miles north east of Cashiers, North Carolina
within Jackson County. Please find enclosed for your review the following

JURISDICTIONAL DETERMINATION
A jurisdictional delineation was conducted by EcoEngineering on July 3, 2008.
No wetlands were identified and a total of 1,500 linear feet of perennial stream
(Robinson Creek) were identified during on-site field investigations.

The delineation has not been field verified by the USACE or NCDWQ;
therefore, attached is a NCDWQ Stream Identification form. Attached is an
irrigation supply feasibility analysis (Chinquapin Property Irrigation Supply
Feasibility Analysis, EcoEngineering, August, 2008) was conducted to
determine the feasibility of making water withdrawals from Robinson Creek for
irrigation purposes on the Chinquapin property.
PROPOSED IMPACTS/MIMIZATION:
The Chinquapin property utilizes an existing on-site pond (Tulip Pond) for
irrigation purposes, and requires withdrawing 40,000 to 150,000 gallons of
water a day during years with normal precipitation events. In addition to being
the property's reservoir utilized for irrigation purposes, Tulip Pond is the
headwater for many stream systems located on the property. During abnormally
dry periods and drought conditions, Tulip Pond is supplemented by well water
which withdrawals approximately 12,000 to 20,000 gallons a day. Use of well
water can be unreliable and also may affect other well users in, the area. Ideally,
a withdrawal from Robinson Creek could supplement the use of well water and
provide a reliable water source without potentially affecting nearby well water
users.
A reliable water supply source utilizing Robinson Creek is proposed to
supplement the irrigation system at Tulip Pond during drought conditions.
When Tulip Pond is filled to capacity during normal precipitation events, there
will be no withdrawal from Robinson Creek to Tulip Pond. The predicted
removal rate and overall discharge rate were evaluated to determine the
feasibility of withdrawing water from Robinson Creek without causing an
adverse effect on stream habitat.
Flow data (enclosed) from Robinson Creek obtained on September 16, 2008 at
the proposed withdrawal location indicated a stream flow rate of 1.55 cubic feet
per second. This value equals one million gallons per day (MGD). The
proposed withdrawal rate during dry periods will be approximately 0.075 MGD
or 7.5 percent of the flow. Analysis conducted during the Chinquapin Property,
Irrigation Supply - Feasibility Analysis (EcoEngineering, August 2008) indicate
that withdrawing approximately 20 percent of the average base flow from
Robinson Creek should be within the variability range of a natural system and
should not adversely affect stream habitat. Since the proposed withdrawal is
only 7.5 percent of the total flow in the creek, adverse impacts from the
withdrawal are not expected.

Within Robinson Creek, the proposed location of the irrigation pump system
will be placed within an upstream section which avoids wetlands and minimizes
potential hydrologic impacts to wetlands which may be located downstream
along Robinson Creek. The proposed location is also conducive in maintaining
the natural flow variability of the stream; therefore, adverse effects of water
withdrawal are not expected to impact species which require specific riffle and
pool habitats. The proposed pump installation will allow low flow passage of
water and aquatic life.
The proposed project will permanently impact 15 linear feet (300 square feet) of
stream channel and will have 25 linear feet (650 square feet) of temporary
impacts within the stream. There will be a total of 10 cubic yards of permanent
fill within the stream associated with the pump.
Robinson Creek's DWQ Stream Index Number is 2-79-13 and has a Water
Quality Classification of WS III (Water Supply III) and TR (Trout Waters). The
proposed pump installation is a water dependent activity with diminimus
increases in impervious surfaces; and therefore, riparian buffers normally
associated low or high development projects near or in WS III waters do not
apply. However, 25 foot Trout Water riparian buffers do apply. A 6 foot wide
temporary access entrance to Robinson Creek will impact the 25 foot Trout
Water riparian buffer perpendicularly. The temporary access entrance will be
seeded within 10 days of installation and will not be maintained. Therefore,
approximately 150 square feet of Trout Water riparian buffers will be
temporarily impacted associated with the installation of the water withdrawal
pump system.
Installation of the water withdrawal pump system will be conducted in the dry
and in accordance with sediment and erosion control requirements contained
within the NC Design Standards in Sensitive Waters. During the installation of
the water withdrawal pump system, temporary stream impacts will likely occur.
These impacts primarily include increased sediment from the temporary
disturbance of the stream bed. These impacts are not expected to create a
significant adverse effect on the stream habitat because installation will be
completed in a short amount of time and disturbance will be minimized.
Installation of the water withdrawal pump system will be scheduled during low
flow periods.

MITIGATION:
The entire project was designed to avoid and minimize impacts to Robinson
Creek. If withdrawal rates remain within the range that represents the natural
flow variability of Robinson Creek, adverse effects of water withdrawal are not
expected. Proper sedimentation and erosion control methods will be utilized
during construction. The proposed project will permanently impact 15 linear
feet (300 square feet) of stream channel and will have 25 linear feet (650 square
feet) of temporary impacts within the stream. There will be a total- of 10 cubic
yards of permanent fill within the stream associated with the pump. Since
stream impacts total only. 40 linear feet of stream, mitigation is not proposed at
this time, due to the avoidance and minimization on-site.,
In conclusion, the applicant proposes to construct a water withdrawal pump
system within Robinson Creek to supplement and maintain pool level in Tulip
Pond during abnormally dry periods or drought conditions. The proposed pump
system will permanently impact 15 linear feet of stream channel and will have
25 linear feet of temporary impacts within the stream. In addition,
approximately 150 square feet of Trout Water riparian buffers will be
temporarily impacted associated with the installation of the water withdrawal
pump system. There are no other impacts associated with this project and
mitigation is not proposed at this time.
Consideration of this project is greatly appreciated. If you should have any

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The Chinquapin property utilizes an existing on-site pond (Tulip Pond) for irrigation purposes, and requires withdrawing
40,000 to 150,000 gallons of water a day during years with normal precipitation events. In addition to being the property's
reservoir utilized for irrigation purposes, Tulip Pond is the headwater for many stream systems located on the property.
During abnormally dry periods and drought conditions, Tulip Pond is supplemented by well water which withdrawals
approximately 12,000 to 20,000 gallons a day. Use of well water can be unreliable and also may affect other well users in
the area. Ideally, a withdrawal from Robinson Creek could supplement the use of well water and provide a reliable water
source without potentially affecting nearby well water users.
A reliable water supply source utilizing Robinson Creek is proposed to supplement the irrigation system at Tulip Pond
during drought conditions. When Tulip Pond is filled to capacity during normal precipitation events, there will be no
withdrawal from Robinson Creek to Tulip Pond. The predicted removal rate and overall discharge rate were estimated to
evaluate the feasibility of withdrawing water from Robinson Creek without causing an adverse effect on stream habitat.
Flow data (enclosed) from Robinson Creek obtained on September 16, 2008 at the proposed withdrawal location
indicated a stream flow rate of 1.55 cubic feet per second. This value equals one million gallons per day (MGD). The
proposed withdrawal rate during dry periods will be approximately 0.075 MGD or 7.5 percent of the flow. Analysis
conducted during the Chinquapin Property, Irrigation Supply - Feasibility Analysis (EcoEngineering, August 2008) indicate
that withdrawing approximately 20 percent of the average base flow from Robinson Creek should be within the variability
range of a natural system and should not adversely affect stream habitat. Since the proposed withdrawal is only 7.5
percent of the total flow in the creek, adverse impacts from the withdrawal are not expected.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Within Robinson Creek, the proposed location of the irrigation pump system will be placed within an upstream section
which avoids wetlands and minimizes potential hydrologic impacts to wetlands which may be located downstream along
Robinson Creek. The proposed location is also conducive in maintaining the natural flow variability of the stream;
therefore, adverse effects of water withdrawal are not expected to impact species which require specific riffle and pool
habitats. The proposed pump installation will allow low flow passage of water and aquatic life.
Installation of the water withdrawal pump system will be conducted in the dry and in accordance with sediment and
erosion control requirements contained within the NC Design Standards in Sensitive Waters. During the installation of the
water withdrawal pump system, temporary stream impacts will likely occur. These impacts primarily include increased
sediment from the temporary disturbance of the stream bed. These impacts are not expected to create a significant
adverse effect on the stream habitat because installation will be completed in a short amount of time and disturbance will
be minimized. Installation of the water withdrawal pump system will be scheduled during low flow periods.

Irrigation Supply - Feasibility Analysis • Chinquapin Property
Jackson County, North Carolina • TRL-08000 • August 2008
Executive Summary
The purpose of this study is to determine the feasibility of making water withdrawals from
Robinson Creek for irrigation purposes on the Chinquapin property. The study contains several
parts that determine the overall feasibility of any withdrawals and the appropriate withdrawal rate at
different times during the year. The findings outlined in this report indicate that a water
withdrawal from Robinson Creek is a feasible option to augment and potentially fulfill the
irrigation needs of the property. This conclusion is based in a limited habitat and stream
assessment and an estimate of discharge and potential water withdrawal from Robinson Creek.
The collection of on-site data will confirm the results of this study and provide a basis to manage
the withdrawal operation.
To determine an acceptable rate of irrigation withdrawal from the assessed stream section, analyses
were performed on USGS stream gage data from nearby streams in the Blue Ridge Ecoregion.
Data for stream discharge and flow rate variability is not available for the proposed Robinson
Creek withdrawal site, so it was necessary to extrapolate from available stream gage data and arrive
at a reasonable irrigation withdrawal rate that would not adversely impact the downstream stream
reach.
Based on information provided to EcoEngineering, the Chinquapin course requires approximately
150,000 gallons of water applied every second non-rain day during normal conditions and
approximately 50,000 gallons daily by hand application during extremely dry conditions. On-site
storage provides approximately 120,000 gallons of water for every six (6) inches of depth in the
current irrigation pond. Estimates developed during this study indicate that withdrawing
approximately 20 percent of the average base flow from Robinson Creek should be within the
variability range of a natural system and should not adversely affect stream habitat. USGS gage
data were used to extrapolate an average discharge for Robinson Creek. The estimated variability
was applied to this data and yielded estimated water withdrawal rates that ranged from 50,000
gallons per day to 120,000 gallons per day based on time of year.
Temporary stream impacts will likely occur during installation of the water withdrawal equipment.
These impacts primarily include increased sediment from the temporary disturbance of the stream
bed. These impacts are not expected to create a significant adverse effect on the stream habitat on
the condition that installation is completed in a short amount of time and disturbance is minimized.
It is recommended that construction activities of the water withdrawal system be scheduled during
dry or low flow periods. If withdrawal rates remain within the range that represents the natural
flow variability of the stream, adverse effects of water withdrawal are not expected. Managing the
water withdrawal from the stream with minimal adverse effect will be possible once on-site data is
collected regarding stream level and withdrawal rate.
The permitting agencies associated with the project include the Army Corps of Engineers
(USACE) and the North Carolina Division of Water Quality (DWQ). Pre-construction notification
and approval form the USACE will be required for any wetlands and/or stream impacts. The
processing time for a NWP pre-construction notification is 45 days with the USACE and 60 days
for DWQ. The installation of a pump system/in-stream structure and withdraw from Robinson
Creek would qualify for a USACE Nationwide Permit (NWP 7). A State DWQ Water Quality

federal species of concern that may exist in the Robinson creek habitat. Table 2 lists stream
features within the assessment area based on the permit classification process. Tables 3 through 7

based on the surrounding topography. Figure 3 is a more detailed project site map that includes the
area observed during the natural resource and habitat stream assessment. Figure 4 shows the
locations of the USGS Gage Stations relative to the project site. Figures 5 through 8 contain charts
of USGS gage data. Figures 5 through 7 show monthly average discharges for the Reed Creek,
Cathy's Creek and Cullasaja stations respectively. Minimum and maximum monthly discharges are
plotted as well as error bars showing the standard deviation above and below average discharge.
Figure 8 shows the average discharge vs. drainage area for each of the USGS gage sites and is

1.0 Proiect Site Identification and Location
Robinson Creek is located within the Little Tennessee River Basin (Hydrologic Unit Code
06010203) (USGS, 1974) and more specifically within the 02 sub-basin of the Little Tennessee
River Basin which is in the western portion of the Blue Ridge Ecoregion (Griffith et al., 2002).
Robinson Creek is located approximately 4-miles northeast of Town of Cashiers within Jackson
County. Approximately 1,500-feet of Robinson Creek was evaluated as part of this initial stream
habitat assessment. The assessment began at a bridge near the confluence of Robinson and Packs
Creek and ended at the confluence of Robinson Creek and Mill Creek. Figure 3 in Appendix 1
depicts the assessment area.
2.0 Summary of Existing Water Needs
Based on information provided to EcoEngineering, the Chinquapin course requires approximately
150,000 gallons of water applied every second non-rain day during normal conditions and
approximately 50,000 gallons daily by hand application during extremely dry conditions. On-site
storage provides approximately 120,000 gallons of water for every six (6) inches of depth in the
current irrigation pond.
3.0 Natural Resource and Habitat Assessment of Proposed Withdrawal Area
An initial stream habitat assessment was conducted for approximately 1,500-feet of Robinson
Creek. Figure 3 in Appendix 1 depicts the assessment area. The stream habitat assessment
consisted of a review of natural resource information sources and photographs (Appendix 2) of the
stream reach. A preliminary on-site inspection was conducted on July 3, 2008 with the intent of
identifying habitat within the stream reach and conducting cursory observations of fish and
macrobenthic species. Detailed stream surveys evaluating dimension, pattern, profile, and bed
material were not conducted, nor were fish or macrobenthic surveys conducted. Stream
conditions can change over time with variations of on-site and surrounding land use(s); and
therefore, this stream habitat assessment only evaluated recognized conditions at the time of the
assessment, and does not address conditions at a given time in the future. This stream habitat
assessment is not definitive and should not be assumed to be a complete or specific definition of all
conditions located within the stream reach. Specific habitat conditions and species composition
may differ from the implied cursory observations and can be most reliably evaluated through
specific stream survey methodologies which are beyond the scope of this stream habitat
assessment.

3.1 Description of Habitat
3.1.1 Regional Habitat
Robinson Creek is located within the Little Tennessee River Basin (Hydrologic Unit Code
06010203) (USGS, 1974). The North Carolina Department of Environment and Natural
Resources - Division of Water Quality (DWQ) has assigned it stream index number of 2-79-13
and a classification of Water Supply III (WS-III) and Trout Waters (Tr) (NCDENR, 2008). Water
Supply III waters are used as sources of water supply and are generally in low to moderately
developed watersheds. The Trout Waters classification is supplemental classification intended to
protect freshwaters for natural trout propagation and survival of stocked trout. This classification is
not the same as the NC Wildlife Resources Commission's Designated Public Mountain Trout
Waters designation.
Robinson Creek is located within the 02 subbasin of the Little Tennessee River Basin which is
western portion of the Blue Ridge Ecoregion. Water quality in the basin is generally excellent.
The Appalachian elktoe and the littlewing pearlymussel, both federally listed as endangered
species, are found in the basin. The primary problem in this basin is nonpoint source pollution,
including inputs of sediment and/or nutrients. Although much of this subbasin is forested,
development is often located along stream corridors. Farmland and new residential areas are
typically found adjacent to streams, often with inadequate riparian buffer zones. According to the
Basinwide Plan (NCDENR, 2005) there is evidence of habitat problems within the subbasin in the
form of few pools, relatively uniform riffles and runs, and embedded riffle substrate. These
problems have shown to have less effect on the benthic macroinvertebrates than the fish fauna
(NCDENR, 2005).
3.1.2 Proiect Site Habitat
Physical habitat was characterized in general accordance with methodology prescribed using in the
1999 by the United States Environmental Protection Agency as part of its Rapid Bioassessment
Protocols for Use in Streams and Wadeable Rivers: Periphyton, Benthic Macroinvertebrates, and
Fish, second edition. Robinson Creek is approximately 6-feet wide at the bridge and becomes
wider further downstream. There are areas along the reach which measure as wide as 40-feet wide;
however, on average the stream is approximately 20-feet wide (Photo 1, Appendix 2). Water
depths within riffles areas range from 3 to 7-inches deep and within pools 2 to 3.5-feet deep. One
example riffle area located approximately 225-feet downstream from the bridge is 18-feet wide, 6-
inches deep and 15-feet long (Photo 2, Appendix 2). One example pool located approximately
100-feet downstream of the bridge is 15-feet wide, 2.5 feet deep, and 30-feet long (Photo 3,
Appendix 2). The reach, as a whole, has characteristics of a Class B stream based on the Rosgen
system of classification (Rosgen, 1997). The reach is mostly characterized by wide and shallow
sections; however, there are three waterfall locations which have characteristics of a Class A
stream. The first water fall (Photo 4, Appendix 2) is approximately 150-feet downstream from the
bridge and is approximately eight (8) feet high. The second water fall (Photo 5, Appendix 2) is
500-feet downstream from the bridge and is approximately 25-feet high. The third water fall
(Photo 6, Appendix 2) is 1,500-feet downstream from the bridge and is approximately 45-feet

The entire reach has a very wide vegetative riparian zone on either side of the stream. With the
exception of the 30 to 40-foot wide stream areas and the areas around the water falls, there is near
continuous canopy coverage over the streambed. The submerged aquatic vegetation known as
water milfoil (Myriophyllum aquaticum) was observed within pools located closer to the bridge.
There were no adjacent wetland areas observed along the reach.
Overall, the substrate of the reach was comprised of a mixture a bedrock (10%) boulder (30%),
rubble (30%), gravel (20%), and sand (10%). The reach was slightly embedded and contained
minor sediment deposition with only one mid-channel bar and a few small point bars. Snags, logs,
and root mats were observed in areas of the reach closer to the bridge.
The reach frequently meanders with higher sinuosity occurring near the bridge. The occurrence of
riffles and pools is relatively frequent with almost no erosion along the banks of the stream.
3.2 Species Identified
3.2.1 Species Identified
Investigations entailed walking within the streambed and making visual observations with the
occasional sampling of stream substrate, logs, and root mats. Benthic macroinvertebrate species
observed within the stream included the caddisfly (Ephemeroptera), mayfly (Plecoptera),
dragonfly (Odonata), and beetle (Coleoptera) orders and were located within sampled riffle
sections of the reach. No fish, mussel, clam, or snail, species were observed at the time of these
investigations. Detailed, fish or macrobentic surveys were not conducted as part of this initial stream
habitat assessment.
3.2.2 Species of Concern
Plants and animals with Endangered or Threatened status are protected under the Endangered
Species Act (ESA) of 1973 (16 US 1531 et seq.). The following species in Table 1 are listed for
Federal protection in Jackson County by the FWS as of July 18, 2008 which may inhabit Robinson
Creek. The status of "Endangered" refers to a species "which is in danger of extinction throughout
all or a significant portion of its range" (ESA, Section 3). Federal Species of Concern (FSC) are
not legally protected under the Endangered Species Act and are not subject to any of its provisions,
including Section 7, until they are formally proposed or listed as Threatened or Endangered. The
table below includes FSC species for Jackson County which may inhabit Robinson Creek.

Note:
E - "Endangered" denotes a species in danger of extinction throughout all or a significant portion of its range.
FSC - denotes Federal Species of Concern
SC - A Special Concern species is one which requires monitoring but may be taken or collected and sold under regulations adopted
under the provisions of Article 25 of Chapter 113 of the General Statutes (animals) and the Plant Protection and
Conservation Act (plants). Only propagated material may be sold of Special Concern plants that are also listed as
Threatened or Endangered.
SR - A Significantly Rare species is not listed as "E", "T", or "SC", but which exists in the state in small numbers and has
been determined to need monitoring.
Robinson Creek is classified by DWQ as Trout Waters, and as such, it plays an important
ecological role in the propagation and survival of trout species. Trout species, such as the rainbow
trout (Oncorhynchus mykiss), brown trout (Salmo tutta), and brook trout (Salvelinuss fontinalis)
found in North Carolina, prefer cold to cool water stream ranging from 40 to 64 degrees. All trout
are opportunistic feeders, eating insects, crustaceans, crayfish, salamanders, frogs, snails, leeches,
and other fish. Within a stream, brown trout have a propensity to congregate near deep pools,
rainbow trout tend to be in runs and riffles, and brook trout can likely be found in high water
quality head-water streams which are rich in oxygen. Rainbow trout spawn between the months of
March and May, while both the brown and brook trout spawn generally during the time period of
September through February.
3.3 Potential Impact of Proposed Withdrawal
3.3.1 Temporary Impact on Species of Concern
Temporary stream impacts will likely occur during installation of the water withdrawal equipment.
These impacts primarily include increased sediment from the temporary disturbance of the stream
bed. These impacts are not expected to create a significant adverse effect on the stream habitat on
the condition that installation is completed in a short amount of time and disturbance is minimized.

Irrigation Supply- Feasibility Analysis • Chinquapin Property

Sediment released from the stream bed as a result of installation activities have potential to affect
fish and other aquatic life in several ways, including the clogging and abrading of gills and other
respiratory surfaces, affecting the habitat by scouring and filling of pools and riffles, altering water
chemistry, and smothering different life stages. Increased sedimentation may cause decreased light
penetration through an increase in turbidity. Dissolved oxygen rates may be lower as well.
Alteration of stream discharge and changes in surface and groundwater drainage patterns may
result from the water withdrawal. Additionally, there may be changes in and destabilization of
water temperature due to vegetation removal. Aquatic invertebrates may drift downstream during
construction and recolonize the disturbed area once it has been stabilized.
3.3.2 Long-term effect on species of concern
After construction of the system and water withdrawal activities have commenced, there may be
alteration of water levels and flows due to withdrawal of surface and groundwater flow. Many of
the listed species of concern prefer streams which have fast to moderate rates of flow and are
located within riffle habitats. Pool habitats are critical as well, providing shelter and breeding
habitat for many fish species such as trout species.
If withdrawal rates remain within the range that represents the natural flow variability of the stream
as discussed in Section 5; adverse effects of water withdrawal are not expected. Managing the
water withdrawal from the stream with minimal adverse effect will be possible once on-site data is
collected regarding stream level and withdrawal rate.
3.3.3 Long-term effect on wetlands downstream of project area
Although there are no wetlands along the reach of Robinson Creek evaluated as part of this initial
stream habitat assessment, wetlands located downstream potentially may be hydrologically
impacted due to alterations of water levels and flows. A reduction of water levels could potentially
affect wetland areas downstream within the floodplain which are dependent upon seasonal and
temporary flooding. The saturated soil conditions within wetlands systems allows for the uptake
and transport of pollutants, nutrients, and carbon in addition to supporting wildlife diversity such as
invertebrates and amphibians. A reduction of wetlands could potentially reduce water quality, and
in turn, may be detrimental to trout species and other species of concern.
4.0 Preliminary Wetland and Stream Permitting
This section outlines the basic permitting framework associated with the project. A summary of
the jurisdictional stream features associated with the project is shown in Table 1. Pennitting
requirements and possible permitting strategies associated with implementation of the irrigation
plan are also presented in this section. The two primary permitting agencies of concern are the U.S.
Army Corps of Engineers (USACE) and NC Division of Water Quality (DWQ). An on-site
inspection was conducted on July 3rd, 2008 and the following were identified within the
assessment area.

4.1 Permitting Stream Impacts
4. 1.1 USACE / DWQ Permitting Overview
A U.S. Army Corps of Engineers (USACE) Nationwide Permit (NWP) can be utilized if the
project is designed to impact less than 0.50-acre of jurisdictional wetlands/waters of the U.S.
including a maximum of 300 linear feet of important/mitigatable stream channel impact. Pre-
construction notification and approval form the USACE will be required for any wetlands and/or
stream impacts. Currently, notification and approval by DWQ is required only for wetland impacts
greater than 0.10-acres. The processing time for a NWP pre-construction notification is 45 days
with the USACE and 60 days for DWQ. All projects qualifying under a NWP are required to
submit a report (post-construction notification) within 30 days of completing the construction
activity describing and quantifying the impacts and stating that the conditions of the NWP have
been adhered to.
Cumulative impacts for the project over the specific NWT thresholds of 0.50-acres of wetlands
and/or 300 linear feet of important/mitigatable stream channel will require an Individual Permit
(IP). Vs require an analysis to determine that the proposed impact to waters of the U.S. is the least
environmentally damaging practical alternative, typically require compensatory mitigation,
notification to adjacent property owners, a public notice, and may require a public hearing.
Currently, it is not anticipated that an individual permit will be needed on this project
The installation of a pump system/in-stream structure and withdraw from Robinson Creek would
qualify for a USACE Nationwide Permit (NWP 7) - "Outfall Structures and Associated Intake
Structures" since the associated impacts would be less than 300 linear feet of stream and there is
not any additional stream impoundment associated with this option. A State DWQ Water Quality
Certification (WQC) #3624 would also be issued in conjunction with the NWP 7, to satisfy
sections 401 and 404 of The Clean Water Act. The utilization of these permits and there review
assumes that there will be no reservoir construction along the channel.
An application in the form of a pre-construction notification (PCN) with exhibits would be
submitted both to the USACE and DWQ for the installation and withdraw from Robinson Creek.
The processing time for the NWP 7 is 45 days with the USACE and 60 days for the WQC
#3624 with DWQ. Typically the USACE and/or DWQ will forward this application to the NC
Division of Water Resources, US Fish and Wildlife Service, and the NC Wildlife Resources
Commission to determine if there is a likelihood of affecting endangered species and

downstream water resources. The contents of this report could also be provided to the agencies
upon request to provide additional habitat background information.
5.0 Review and Analysis of Historical Stream Records and Existing Data
The predicted removal rate and overall discharge rate were estimated to evaluate the feasibility of
withdrawing water from Robinson Creek without causing an adverse effect on stream habitat. The
evaluation approach was based on the assumption that all streams have an inherent natural flow
variability and that if a withdrawal rate stayed within an observed natural range, then any adverse
effects would be minimized to the greatest extent possible. No site specific data was available at
the time of the study; therefore, gage data from three (3) USGS gage locations within the Blue
Ridge Ecoregion were used in this analysis.
A stream discharge rate was estimated for the proposed Robinson Creek withdrawal site based on
the relationships between drainage area and discharge observed at the USGS gage sites. The
variation in the Robinson Creek discharge was then extrapolated using the discharge variation
observed in the USGS gage data. This variation was then applied to the estimated Robinson Creek
discharge to yield a daily water amount that could be withdrawn from Robinson Creek. This water
withdrawal would be well within the expected natural flow variation of the stream and should have
a minimal impact. Once actual site data is available, a more accurate estimate of stream flow can
be determined as data is collected over time.
5.1 USGS Gage Data and Locations
5. 1.1 USGS Gage Data
Historical USGS Stream Gage data was collected for three (3) sites in Western North Carolina.
USGS Daily stream discharge records are derived from time-series data for each day within the
period of record. The time-series data, sometimes referred to as instantaneous or real-time data,
may be collected as often as every minute. Daily mean discharge is derived from the time-series
data and historical records are available online through the USGS water data site (USGS, 2008).
Three USGS Stream gage sites were selected based on the proximity to the proposed Chinquapin
stream withdrawal location (35°10'45"N 83°04'00"W). The drainage area to this site, located at the
confluence of Packs Creek and Robinson Creek is 1.96 square miles.
5.1.2 Gage Locations
Gage Site #1 is located on Reed Creek near Asheville, North Carolina. (USGS Gage #03451510)
The drainage area to this location is approximately 2.13 square miles. Daily data was utilized for
the entire period of record, spanning July 1986 to December of 1988.
Gage Site #2 is located on Cathey's Creek near Brevard, North Carolina. (USGS Gage #03440000)
The drainage area to Site #2 is approximately 11.70 square miles. Daily data was utilized for the
period of record from January 1986 to September 2004.

Gage Site #3 is on the Cullasaja River at State Route 1620. (USGS Gage #0350056050) The
drainage area to Site #3 is approximately 18.8 square miles. Daily data was utilized for the entire
period of record from July 2001 to July 2008.
See Figure 4 for a map of USGS Stream Gage locations.
5.2 Gage Data Processing and Analysis
5.2.1 Data Compilation and Quality Control
Extremely high discharge values, likely from hurricane events, produced skewed data sets and were
removed to reduce data variance. This approach was conservative because reducing the variability
in the data set would also reduce the predicted natural stream flow variability. Outlying high-flow
data points that were more than three (3) standard deviations were removed from the analysis
(Walpole and Myers, 1993). These points representing extremely high flow days were removed in
order to reduce upward bias caused by infrequent heavy rainfall events and to reduce the variance
of the data of interest. Table 3 provides a summary of the data obtained from each gage site.
Table 3. USGS Gage Data Summa

Number of Data Points 915 6,544 2,567
Number of Points Removed 29 102 47
% of Initial Dataset Removed 3.2% 1.6% 1.8%
5.2.2 Discharge Calculations
Monthly average discharges were recalculated for each gage site once the outlying points were
removed from the datasets. These monthly averages used the USGS derived daily data for each
month across the entire period of record at each gage site. For each gage site, a plot was created
that shows the average monthly discharge. The plot also shows the maximum and minimum
discharge value for each month based on the entire period of record. The recalculated standard
deviation is shown as a bar extending above each monthly average data point. These represent a
measure of the variance in discharge above the average at each site. Please see Figures 5 through 7
for the monthly discharge plots. Table 4 contains the average discharge for each gage site based on
three-month time spans.

5.2.3 Below Average Discharge Variation
In order to more accurately reflect the variation in discharge below the monthly average discharge
values, a dataset was created that contained only daily discharge data for days that this value was
below the monthly average. Below average discharges were chosen because the proposed
withdrawals from the Chinquapin site would have the greatest impact when stream flows are below
average. The standard deviation for the below-average discharge was calculated to show the natural
variation in discharge during low-flow periods. This standard deviation is represented on the plots
for each site by the bar extending below each monthly average discharge point. Please see Figures
5 through 7 for the appropriate discharge plots.
For clarity, the variability for each site during each month was compiled into Table 5.
The percentage shown for each month represents the below average flow value as a percent of the
average flow. These figures provide a rough estimate of the natural variability in site discharges
when the discharge is below the monthly average. The composite percentages represent the average
of the variability for all three sites. The quarterly percentage is based on the average of the
composite percentage for each three-month time span. As mentioned earlier, the periods when
stream discharges are below average are of particular importance when considering the impact of
Chinquapin irrigation withdrawals. This comparison table provides a baseline variability
measurement for the three USGS stream gage locations and an important reference point for the
analysis of the proposed Chinquapin withdrawal site. This analysis is discussed further below.

5.3 Analysis and Assessment of Proposed Withdrawal Site
5.3.1 Calculated Discharge at Chinquapin Withdrawal
A drainage area to average discharge relationship was calculated during each three-month quarter
based on the average discharges shown in Table 4. A best fit trendline was calculated for each
three-month period based on the relationship between average discharge and drainage area. Trend
lines calculated for each quarter can be found in Appendix 1, Figure 8. Table 6 shows the

calculated quarterly average flow rates at the proposed Trillium irrigation withdrawal site. These
values are based on the trendlines calculated from the known flows at the USGS gage sites and use
the measured drainage area of 1.96 square miles at the proposed withdrawal site. These discharge
values are for planning purposes only and will be replaced with actual site data once it is collected.

Maximum quarterly withdrawal rates were estimated at the proposed Trillium withdrawal site
based on the results of Table 6 and the quarterly variation results in Table 5. The withdrawal
figures provided in Table 7 represent a withdrawal rate that will fall within the natural variation of
flow rate based on the average quarterly discharge rate for the proposed withdrawal site.

6.0 Summary and Conclusions
The findings outlined in this report indicate that a water withdrawal from Robinson Creek is a
feasible option to augment and potentially fulfill the irrigation needs of the property. This
conclusion is based in a limited habitat and stream assessment and an estimate of discharge and
potential water withdrawal from Robinson Creek. The collection of on-site data will confirm the
results of this study and provide a basis to manage the withdrawal operation.
Based on information provided to EcoEngineering, the Chinquapin course requires approximately
150,000 gallons of water applied every second non-rain day during normal conditions and
approximately 50,000 gallons daily by hand application during extremely dry conditions. On-site
storage provides approximately 120,000 gallons of water for every six (6) inches of depth in the
current irrigation pond. Estimates developed during this study indicate that withdrawing
approximately 20 percent of the average base flow from Robinson Creek should be within the
variability range of a natural system and should not adversely affect stream habitat. USGS gage
data were used to extrapolate an average discharge for Robinson Creek. The estimated variability
was applied to this data and yielded estimated water withdrawal rates that ranged from 50,000
gallons per day to 120,000 gallons per day based on time of year. These estimates may increase or
decrease when applied to actual discharge data obtained from the project site. The preliminary
estimates indicated that water storage for irrigation may be necessary due to target consumption
rates exceeding estimated production rates.
Temporary stream impacts will likely occur during installation of the water withdrawal equipment.
These impacts primarily include increased sediment from the temporary disturbance of the stream
bed. These impacts are not expected to create a significant adverse effect on the stream habitat on
the condition that installation is completed in a short amount of time and disturbance is minimized.
It is recommended that construction activities of the water withdrawal system be scheduled during
dry or low flow periods.
If withdrawal rates remain within the range that represents the natural flow variability of the stream,
adverse effects of water withdrawal are not expected. Managing the water withdrawal from the
stream with minimal adverse effect will be possible once on-site data is collected regarding stream
level and withdrawal rate.
The permitting agencies associated with the project include the Army Corps of Engineers
(USACE) and the North Carolina Division of Water Quality (DWQ). Pre-construction notification
and approval form the USACE will be required for any wetlands and/or stream impacts. The
processing time for a NWP pre-construction notification is 45 days with the USACE and 60 days
for DWQ. The installation of a pump system/in-stream structure and withdraw from Robinson
Creek would qualify for a USACE Nationwide Permit (NWP 7). A State DWQ Water Quality
Certification (WQC) #3624 would also be issued in conjunction with the NWP 7, to satisfy
sections 401 and 404 of The Clean Water Act.

Re: Stream Flow Monitoring Data
Goldie Project No. 1312.1
Dear Mr. Howe:
ASSOCIATES
engineering, environmental
and laboratory services
Please find enclosed the above referenced flow monitoring data as conducted by Goldie
and Associates on September 16, 2008 for the Packs Creek location on the Chinquapin
property. Flow was recorded using a Global Water FP-101 Flow Probe, measuring feet
per second (ft/s) flows across the designated channel at one foot width intervals. We
have enclosed maps indicating the location of the sampling, a cross sectional diagram of
the channel, and the field measured and tabulated total flow data; total daily flow was
calculated to be 1.00 million gallons per day (MGD). Additionally, please note that the
stream was noted to be in relative low flow conditions as the ordinary high water mark
(OHWM) was noted to be several inches higher than the current top of water.
We appreciate this opportunity to serve; please contact us if you have questions or require
additional information.
Sincerely,
Goldie and Associates
