Waste Treatment Facilities
Stormwater
• The project will utilize awetlands-type retention basin and will be designed in
strict accordance with the requirements of Buncombe County and NC DENR.
Attached is a memo from Freeland and Kauffinan Inc. summarizing the Storm
Water Management Design. ~ 5-~- ~ 2~D(c~ yr-~-~'
~ a~~ ~
Wastewater rt l I
• The site will tie into existing sewer lines, so all wastewater will be treated by the
Metropolitan Sewerage District of Buncombe County, NC.
Mitigation Plan
An onsite mitigation meeting took place October 11, 2006 with NCDENR,
USACE, FWS, and NCWRC. Based on discussions regarding the proposed mitigation
plan, we revised the plan to eliminate the priority 2 stream restoration in favor of stream
enhancement and spot stabilization, due to the lack of buffer available. We have revised
the wetland mitigation by eliminating the onsite wetland creation in favor of utilizing the
Ecosystem Enhancement Program (EEP). A complete revised on-site mitigation plan is
included for your review. Monitoring reports will be submitted to both the USACOE and
NC DWQ for review.
Avoidance and Minimization
Included in Appendix A are five site layouts. The first layout is the original site
plan submitted in the permit application, dated May 8, 2006. The second layout is the

1. MITIGATION GOALS AND OBJECTIVES
Impact Overview
This plan is being submitted by the Wal-Mart Real Estate Business Trust to mitigate for
proposed impacts associated with the construction of the Airport Road Retail Center.
The impacts that are being compensated for include 1.59 acres of wetlands and 504 linear
feet (0.321 acres) of stream/linear wetland.
Stream Mitigation Overview
• To compensate for the proposed stream impacts, this mitigation plan encompasses
a combination of stream relocation/establishment and stream enhancement
activities. A total of 570 linear feet of stream will be improved by the proposed
activities.
• All activities are proposed to take place onsite.
• The overall goals and purpose of the project are to reconnect and enhance
previously disturbed onsite waters.
Stream Relocation/Establishment Area (Unit 1): The linear system being
impacted enters the property through an existing pipe, the proposed
activities would extend the pipe and redirect the waters into an existing
ephemeral channel. Approximately, 1601inear feet of ephemeral channel
will be enhanced to accommodate the new flow.
Stream Enhancement Area (Unit 21: As shown in the mitigation overview
figures in Appendix 1, the Stream Relocation/Enhancement Reach flows
into an existing intermittent/perennial system. The existing stream contains
large amounts of solid waste and debris, as well as several areas of bank
failure. The proposed activities will enhance approximately 4101inear feet
of stream channel.
Wetland Mitigation Overview
• To compensate for the proposed wetlands impacts, the applicant proposes to
utilize the North Carolina Ecosystem Enhancement Program. EEP has agreed to
take responsibility for providing compensatory mitigation for 1.59 acres of impact
up to a 2:1 mitigation-to-impact ratio. The mitigation will be performed in
accordance with the Memorandum of Understanding between NC Department of
Environment and Natural Resources and the US Army Corps of Engineers dated
November 4, 1998.
2. BASELINE INFORMATION OF PROJECT SITE
Eco-Region -The project is located in the French Broad River Basin (USGS Hydrologic
Unit: 06010105). The project area falls within the Blue Ridge EcoRegion. The Blue

Ridge extends from southern Pennsylvania to northern Georgia, varying from narrow
ridges to hilly plateaus to more massive mountainous areas with high peaks. The mostly
forested slopes, high-gradient, cool, clear streams, and rugged terrain occur on a mix of
igneous, metamorphic, and sedimentary geology. Annual precipitation of over 80 inches
can occur on the well-exposed high peaks of the Great Smoky Mountains that reach over
6000 feet above mean sea level. The southern Blue Ridge is one of the richest centers of
biodiversity in the eastern U.S. It is one of the most floristically diverse ecoregions, and
includes Appalachian oak forests, northern hardwoods, and Southeastern spruce-fir
forests. Shrub, grass, and heath balds, hemlock, cove hardwoods, and oak-pine
communities are also significant.
Location- The Airport Road Property consists of approximately 37.287+/- acres and is
located on the west side of Airport Road north of the intersection with I-26 in Buncombe
County, North Carolina. The property is bounded by a mobile home park to the north,
commercial and residential properties to the west, commercial properties to the south, and
Airport Road to the east. A tributary of the French Broad River flows west along a
portion of the northern property boundary. Two small wetlands are adjacent to this
tributary. A linear wetland runs from Airport Road toward the center of the property,
terminating before creating a clear connection with either the tributary or its adjacent
wetlands. To the south and near the center of the property is a larger wetland (1.658
acres) which runs northwest to the property boundary where is connects to the first
tributary. A second u1n tributary of the French Broad River occurs in the southwest
corner of the property and has an associated wetland. The USGS HUC unit is 06010105.
A site location map is provided in the Appendix 1.
The majority of the site was previously harvested for timber. The site is significantly
disturbed with remnant logging debris and rutted out access roads. A protected species
habitat assessment was conducted to determine if habitat for protected species was
present on the property. No federally protected species were identified on the property.
Quantify Wetland Resources - A jurisdictional wetland delineation was conducted on
the property identifying wetlands and waterways. Wetlands, streams and isolated
wetlands comprise 2.59 acres of the property. The first u/n tributary originates on
property and runs east-west along the northern property boundary. The second u/n
tributary run northeast near the western property boundary and includes an associated
wetland. Two small wetland areas are located adjacent and south of the first tributary. A
linear wetland runs east-west from Airport Road towards the center of the property. This
wetland receives runoff from stormwater off Airport Road. A large wetland is located in
the center of the property and runs northwest to the northern portion of the western
property boundary.
Existing Hydrology- Hydrologic characteristics on the property are based on local
rainfall and overflow of the unnamed tributaries of the French Broad River located near
the northern boundary of the property. Stormwater run off from Airport Road enters the
site from a culvert near the center of the eastern property boundary.
4

Existing Vegetation- The majority of the property is considered disturbed by past land
use practices. Existing vegetation consisted primarily of early successional species.
Large areas of Smilax sp. and Juncus effuses were present as well as Virginia pine (Pinus
virginiana), sawtooth blackberry (Rubus argutus), sweetgum (Liquidambar styraciflua),
tulip poplar (Liriodendron tulipifera), hazel alder (Alms serrulata) and rhododendron.
Existing Soils- The dominant soils within the project area are Tate-Urban Land Complex
and Fannin Loam. Prior site disturbance and soil compaction have resulted in gleyed or
low-chroma color hydric soils with a hue of SY 5/2 and SY 5/1. A USDA soils map is
included in Appendix 1.
Slopes on the property ranged from nearly level to 12%. Soils identified on the property
included the following:

3. UNIT 1: Stream Relocation/Establishment Area
• As shown in pictures included in Appendix 2, the existing ephemeral channel is to
be modified and stabilized to handle the flows redirected into the drainage by the
proposed pipe. We propose to utilize the same dimension pattern and profile
constraints to be utilized in the adjacent, downstream "Stream Enhancement
Area". The derivation of the proposed channel parameters is described below.
• Total stream channel relocated and enhanced: approximately 160 linear feet.
• The same bank protection and replanting proposed for the "Stream Enhancement
Area" will be applied to this reach.
4. UNIT 2: Stream Enhancement Area
LEVEL II STREAM ASSESSMENT
Data collected during the Level II stream survey included, but not limited to: thalweg,
edge of water, water surface, bankfull, top of low bank, width (channel, bankfull), depth
(mean, bankfull, max) and slope. All elevations were measured using a surveyor's rod
and level. Data collected during the analysis is presented in Appendix 2.

• DIMENSION
Stream dimension is measured by the cross section data. Key features along the cross
section are identified including top of bank, breaks in slope along the cross section,
bankfull, edge of water and the thalweg.
These measurements are used to determine and calculate the following stream
dimensions and ratios; bankfull cross sectional area, bankfull width, mean and max
bankfull depth, width/depth ratio, width of flood prone area, entrenchment ratio, and
bank height ratio. The width of flood prone area is the width measurement at an
elevation twice the maximum bankfull depth. The entrenchment ratio is the width of
the flood prone area divided by the bankfull width. The bank height ratio is the height
of the low bank divided by the maximum bankfull depth. These measurements help
determine the degree of vertical containment of the stream channel. Data Summary
sheets for the impaired reach are included in Appendix 2.
PROFILE
The stream channel profile is a description of the gradient and bed facets (riffles,
runs, pools and glides) and the spacing of these facets along the length of the stream.
Profile data is gathered by performing a longitudinal profile of the stream by
surveying the thalweg, edge of water, bankfull and top of low bank (when present) at
least a distance of twenty bankfull widths. Survey data was collected at the top of
each facet. A total of 4101inear feet of the unnamed tributary of the French Broad
River were assessed.
These measurements are used to determine and calculate the following stream
dimensions and ratios; average water surface slope, valley slope, facet slopes, pool to
pool spacing and pool length.
CHANNEL MATERIALS
The channel materials data was collected using the Wolman pebble count methods.
Channel Material Data Summary sheets are included in Appendix 2.
• DATA ANALYSIS
Once the field data was collected it was entered RiverMorph and formulas were
established to calculate the morphological parameters associated with dimension,
profile and channel materials. Estimates of bankfull discharge were determined based
on hydraulic geometry, channel roughness and slope using Manning's equation. ^~

REFERENCE REACH
As shown in figures included in Appendix 3, the chosen reference reach is located on
Little Grove Creek, approximately 51 miles from the project site. This particular
reference was selected because:
^ The valley type, slope and soils are similar to the project area.
^ Many years ago, this reach abandoned it's floodplain, widened and has since
established a bankfull bench and stable form.
^ The reach has been and will continued to be measured annually to monitor
stability.
• BASELINE INFORMATION for Reference Reach
^ ECOREGION
"Tributary K Reference Reach" is located on Little Grove Creek in the Grove
Creek watershed of the Saluda River Basin (USGS Hydrologic Unit: 3,050,109).
The reference area falls within the Southern Lower Piedmont EcoRegion. A site
location map and infrared photo is provided in Appendix 3.
^ SOILS
The dominant soils within the project area are Cartecay sandy loam and Toccoa
sandy loam associations. A USDA soils map is included in Appendix 3.
VEGETATION
The forest along Little Grove Creek has been undisturbed for at least 2 decades.
The forests maintain a diverse assemblage of tree. Some tree species found in the
project area include white oak (Quercus alba), red oak (Quercus rubs), black
oak (Quercus veluntina), chestnut oak (Quercus prinus), maple (Ater rubrum),
poplar (Liriodendron tulipifera), hemlock (Tsuga sp.), sycamore (Platanus
occidentalis), sweet gum (Liquidambar styrac~ua).
• LEVEL II STREAM ASSESSMENT of Reference Reach
Similar to the project reach a Level II Assessment was performed, data collected
during the survey is summarized in Appendix 3.

Data generated from the reference reach was utilized to create dimensionless ratios,
which were utilized a parameters for the stream restoration design.
4. RESTORATION PLAN
• Restoration figures are included in Appendix 4.
• Work in the "Stream Enhancement Area" will involve the removal of all solid waste
debris within the existing channel. In addition, spot stabilization using hand tools and
Bio-D70 matting will occur in areas showing signs of bank failure. More extensive
bank sloping will not take place due to the proximity of the stream to the property
line.
o Dimension Adjustments - "Stream Relocation/Establishment Reach"
• Across section of the proposed channel is included in Appendix 4.
Summaries of the proposed channel dimensions are included in
Appendix 4.
• As shown in the Typical bank stabilization diagram included in
Appendix 4, Bio-D70 matting will be utilized to stabilize the banks
and the banks will be vegetated with a combination of herbs and
woody vegetation. A list of vegetation proposed to be planted can be
found in Appendix 4.
• In-stream structures (cross vanes) will be utilized to prevent down
cutting. They will be placed at the top and bottom of the "Stream
Relocation/Enhancement Reach.
• All of the structures are proposed to be made of rocks, wood or a
combination rock and wood.

5. Mitigation Work Plan.
• All work will be done utilizing current Best Management Practices.
• All disturbed riparian areas will be replanted 8 to 12 ft on center with bare root or
containerized woody trees and shrubs. (Species List in Appendix 4).
Adaptive Management Clause:
• During construction minor changes to the proposed restoration may be made if
more logical or affective means to achieve the projected goals becomes apparent.
Construction Schedule
• All proposed restoration activities will begin once the final grades have been
acquired for the proposed project and adjacent slopes have been stabilized. The
restoration activities will be complete prior to the completion of the construction
of the proposed project.
6. Monitoring and Success Criteria
• 6 monitoring reports over 5 years (a 6-month and 5 annual) will be submitted to
the USACE for review.
• Monitoring reports will include:
o Photographs taken from established photo locations that will depict all of
the restoration sites.
0 4 Permanent cross sections will be established along the enhanced
tributaries. Cross sections will be overlaid with previous reports to
determine if the streams dimension is changing.
o Survival rates of planted woody vegetation in both riparian and wetland
areas will be analyzed utilizing a stem count.

Success Criteria:
o Vegetation success on stream buffer areas will be qualified by 75%
survival.
• Contingency Plan:
If changes to the streams dimension, pattern or profile are deemed to be negative,
leading toward instability, changes to the stream may be made.
o Changes may include:
• Placement of in-stream structures to stabilize the stream.
• Modifying the streams dimension to establish a more appropriate
stream dimension.
• Stabilizing the stream banks with additional coir matting and
vegetation.

**Planting schedules for each species and plant category is dependent on dormancy period and expected germination times.
It is expected that most of the planting will occur during early spring or late fall periods. Vegetation characteristics for the
area will be designed to allow the highest species diversity and greatest vegetation survival rates. Selected species will be
dependent on availability of transplants. All selected species will be native to North Carolina and will be obtained from local
nurseries if possible. The following list includes a selection of species that may be used for the restoration project.
