1.0 INTRODUCTION
An investigation to identify wetlands and other waters of the U.S. within the Baxter Creek
Commercial property was performed on September 4th and 7th, 2020 by Woodard & Curran (WC) for
Hyalite Engineers, PLLC. This delineation was conducted as part of the due diligence to assist with
future land development and infrastructure improvements on property within the Bozeman City
limits. The property encompasses 18.24 acres and is located directly west of the J.C. Billon Auto
Plaza, north of Huffine Lane within the W½ SE¼ SE¼ of Section 9, Township 2 South, Range 5
East in Gallatin County. Primary access to the site is off Huffine Lane. An overall site view or site
vicinity figure (courtesy of the City of Bozeman) is included in Appendix A.
The purpose of the 2020 delineation was to identify areas that satisfy the criteria for wetland and
non-wetland waterways and to delineate their boundaries. This report describes the methods
employed during the September wetland delineation, the delineation results and preliminary
jurisdictional determinations of each wetland and the waterway within the project area based on
current Clean Water Act (June 22, 2020) guidance. This report also provides a map showing the
distribution of wetlands and the waterway. It should be noted that the U.S. Army Corps of Engineers
(USACE also referred to as COE) and Environmental Protection Agency (EPA) reserve the right to
determine jurisdiction on a case-by-case basis (CFR Vol. 51 No. 219). Jurisdiction will ultimately be
decided by USACE and EPA relative to each of the wetlands and waterways delineated within the
project area.
1.1 Site Description
The property lies east of the Phase 4 Norton Ranch Development on a relatively flat, historic
agricultural field used for grazing and hay production. Baxter Creek, a perennial stream that
originates south of Blackwood Road (approximately 3 miles south of Bozeman), enters the property
along the southeastern boundary and continues north-northwest for approximately 977 linear feet
where the creek flows into a culvert under Fallon Street and continues to the north. The creek flows
through developed and undeveloped areas including subdivisions, pasture and cropland as it flows
north toward Aajker Creek. Baxter Creek is a tributary to Aajker Creek, which connects to Hyalite
Creek, a tributary to the East Gallatin River north of Belgrade, Montana. Most of Baxter Creek
crosses the property within a constructed, straight channel but remnants of the original channel were
observed off the property near Huffine Lane and the J.C. Billon Auto Plaza property boundary. A
high berm remains on the east side of the creek channel where excess soil from the excavation was
placed. Baxter Creek is a low energy stream with an herbaceous wetland border that varies in width.
The straightened creek channel is considerably lower in elevation and may have been excavated to
capture excess ground water to improve historic agricultural land use. Elevations across the property
range from approximately 4,830 feet above sea level at the southwest corner to approximately 4,815
feet at the Baxter Creek culvert inlet under Fallon Street to 4,818 feet at the northeast corner.
2.0 REGULATION SETTING
In 1977, an Executive Order was enacted for the protection of wetlands. Revisions to the Clean
Water Act (CWA), specifically Section 404, have made it the principal regulatory tool pertaining to
wetlands and other “waters of the United States”. The objective of wetland protection is “to restore
Baxter Creek Commercial Property
Wetlands and Other Waters of the U.S. Delineation Report October 2020
2
and maintain the chemical, physical and biological integrity of our Nation’s waters” and USACE
enforces the CWA. Placement of dredged or fill material into wetlands or other “waters of the
United States” is regulated by USACE and EPA under Section 404 of the federal CWA.
2.1 Wetland Definition
For delineation purposes, wetlands are defined as:
Those areas that are inundated or saturated by surface or groundwater at a frequency and
duration sufficient to support, and that under normal circumstances do support, a prevalence
of vegetation typically adapted for life in saturated soil conditions (33 CFR 328.3, 40 CFR
230.3).
The interaction of wetland hydrology, hydrophytic vegetation and hydric soil results in the
development of site characteristics unique to wetlands. Consequently, except under certain
circumstances, the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coast Region (COE, 2010) requires that a minimum of one
positive indicator from each of these three parameters be documented to positively delineate an area
as a wetland. In general terms, rivers, streams or drainage ways with a definable bed and bank are
designated as waters of the U.S. under Section 404 of the CWA. In the absence of wetlands, the
limit of USACE’s jurisdiction is where the ordinary high-water mark is no longer perceptible (CWA
Sec. 328.4 (b)). Ditches, open water areas and similar areas are not wetlands, but may be regulated
by USACE and EPA as waters of the United States.
2.2 Waters of the U.S. Definition
Waters of the United States (WOTUS) generally include: waters which were or could be used for
interstate or foreign commerce; all interstate waters including interstate wetlands; all other waters
including intrastate lakes, river, streams (including intermittent streams), mudflats, sandflats,
wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use or
degradation of which could affect interstate or foreign commerce; all impoundments of waters
otherwise defined as waters of the U.S.; tributaries of aforementioned waters; territorial seas; and
wetlands adjacent to aforementioned waters (other than wetlands).
2.3 Regulatory Jurisdiction
The Final Rule - The Navigable Waters Protection Rule: Definition of WOTUS was published on
April 21, 2020 and went into effect June 22, 2020.
The Final Rule identifies four categories of waters that are defined as “waters of the U.S” (WOTUS)
and are considered to be jurisdictional. WOTUS are defined as:
1. The territorial seas and traditional navigable waters;
2. Perennial and intermittent tributaries that contribute surface water flow to such waters;
3. Certain lakes, ponds, and impoundments of jurisdictional waters;
4. Wetlands adjacent to other jurisdictional waters (other than waters that are themselves
wetlands)
Adjacent wetlands are defined as wetlands that:
Baxter Creek Commercial Property
Wetlands and Other Waters of the U.S. Delineation Report October 2020

- Abut a territorial sea or traditional navigable water, a tributary, or a lake, pond, or
impoundment of a jurisdictional water in a typical year;
- Are inundated by flooding from a territorial sea, traditional navigable water, a tributary, or a
lake, pond, or impoundment of a jurisdictional water in a typical year;
o Inundation occurs via flooding and need only occur at least once in a typical year to
establish adjacency for wetlands with no particular requirement for the volume or
duration of inundation.
o Wetlands are not adjacent simply because a hydrologic connection between
jurisdictional waters and wetlands is possible or if, for example, wetlands are
connected by flooding once every 100 years or by directional sheet flow during or
following storm events – instead, wetlands are considered adjacent if they are
inundated by flooding from a WOTUS in a typical year; inundation sufficient to
cause adjacency occurs only in one direction (i.e., from the jurisdictional water to the
wetland).
- Are physically separated from a territorial sea or traditional navigable water, a tributary, or a
lake, pond, or impoundment only by a natural berm, bank, dune, or similar natural feature;
- Are physically separated from a territorial sea or traditional navigable water, a tributary, or a
lake, pond, or impoundment only by an artificial dike, barrier, or similar artificial structure so
long as that structure allows for a direct surface connection in a typical year, such as
through a culvert, flood or tide gate, pump or other artificial feature;
* Abut refers to when a wetland touches a jurisdictional water at least at one point or side.
* An adjacent wetland is jurisdictional in its entirety when a road or similar artificial structure
divides the wetland, as long the structure allows for direct hydrologic surface connection
through or over that structure in a typical year.
* If a wetland can be delineated from another wetland by upland or other separation, then each
wetland will be considered separately for purposes of determining adjacency.
The Final Rule maintains the long-standing regulatory definition of wetlands as those areas that are
inundated or saturated by surface or ground water at a frequency and duration sufficient to support,
and that under normal circumstances do support, a prevalence of vegetation typically adapted for life
in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas.
- The Agencies (USACE and EPA) have clarified that the presence and boundaries of wetlands
are determined based upon an area satisfying all three of the definition’s factors (i.e.,
hydrology, hydrophytic vegetation and hydric soils) under normal circumstances, however;
- Certain wetland indicators may not be present year-round in a typical year due to normal
seasonal or annual variability. Adjacent wetlands under this final rule include wetlands with
alternating hydroperiods and seasonal wetlands with vegetation shifts. The delineated
boundary of seasonal wetland boundary remains constant, even though all three delineation
factors may not be present.
Instances in which ditches can be considered WOTUS and therefore be jurisdictional include:
- Ditches that are constructed in or that relocate a tributary are included in the Final Rule as
tributaries as long as the ditch satisfies the flow conditions of the tributary (i.e., has
intermittent or perennial flow).
Baxter Creek Commercial Property
Wetlands and Other Waters of the U.S. Delineation Report October 2020

- When a ditch constructed in an adjacent wetland contributes less than perennial or
intermittent flow as described by a tributary in a typical year and yet due to lack of
maintenance gains wetland characteristics, that ditch may be viewed as an adjacent wetland if
it meets the definition of both wetlands (i.e., satisfies the hydrology, hydrophytic vegetation
and hydric soils criteria) and “adjacent wetlands”.
3.0 METHODS
3.1 Pre-Field Review
A review of existing literature, maps and other materials was conducted prior to performing the field
work to identify wetlands and other WOTUS including:
• National Wetland Inventory mapping (USFWS)
• Soil Survey of Gallatin County (NRCS, 2020)
• Hydric Soil Lists, Gallatin County (NRCS, 2020)
3.2 Field Methods
The delineation was conducted in accordance with the 1987 U.S. Army Corps of Engineers Wetland
Delineation Manual (Environmental Laboratory, 1987) and the Western Mountains, Valleys, and
Coast Regional Supplement (COE, 2010). Except under certain circumstances, these documents
require the simultaneous presence of wetland hydrology, hydric soils and a dominance (greater than
50 percent) of hydrophytic vegetation during the growing season to positively delineate an area as a
wetland.
3.2.1 Hydrology
Wetland hydrology may be supplied by surface water, groundwater and/or direct precipitation.
Potential wetland sites were examined for primary and secondary indicators of wetland hydrology.
Primary hydrology indicators may include the presence of surface water, saturation in the upper 12
inches of the soil profile, high water table and evidence of reducing conditions at the surface.
Secondary hydrology indicators include observable drainage patterns, a positive FAC-neutral test and
observations of the water table in the upper 18 inches of the soil profile. A sample plot is considered
to meet the wetland hydrology criterion if at least one primary indicator or two secondary indicators
are present.
The delineation was conducted during the early fall under dry climatic conditions with low Baxter
Creek flows due to a drier than average fall precipitation. Climate data from the meteorological
station at Montana State University, Montana [241044], recorded an average annual precipitation
rate of 18.71 inches from April 1957 through December 2019 (Western Region Climate Center,
2020). The historic precipitation average from January through September was 15.23 inches. The
precipitation totals for this same period in 2020 was 11.56 inches, indicating that precipitation during
the growing season in 2020 was below average. The extent of surface water and groundwater across
this site fluctuates seasonally and is moderately driven by direct precipitation and surface runoff.
Precipitation contributes to hydrology within the site with elevated seasonal groundwater levels and

flows from the ditch along the eastern property boundary (Baxter Creek) appearing to be the
principal contributors to wetland hydrology.
3.2.2 Soils
Soils at each representative wetland and upland sample point were typically inspected to a depth of at
least 18 inches to determine the presence or absence of hydric soil indicators based on the Natural
Resource Conservation Service (NRCS) Indicators of Hydric Soils (Version 8.2, NRCS, 2018) and
the Regional Supplement to the U.S. Army Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coastal Region (USACE, 2010). Soil samples were moistened
when necessary to aid in the determination of soil matrix and redoximorphic features (if present),
hue, value and chroma using Munsell Soil Color Charts (Munsell, 2009. Soil texture was evaluated
using field methods described by USACE and the Natural Resources Conservation Service (NRCS).
3.2.3 Vegetation
At each sample point, plant species dominance was visually estimated based on the percent aerial
cover for each species and then recorded. Herbaceous cover was assessed within a 5-foot radius
circular plot (Environmental Laboratory, 1987; USACE, 2010). In accordance with USACE
methodology, greater than 50 percent of the dominant plant species must be classified as hydrophytic
for an area to be a wetland. The indicator status for vegetation was derived from the new Western
Mountains, Valleys, and Coast: 2018 Regional Wetland Plant Lists (USACE, 2018). Accordingly,
plants may be categorized as obligate (OBL), facultative wetland (FACW), facultative (FAC),
facultative upland (FACU) or upland (UPL). If a species does not have an indicator status due to
insufficient information available to determine an indicator status, a no indictor (NI) designation is
utilized. The presence of hydrophytic vegetation within a representative plant community is
positively identified if more than 50 percent of the dominant species within the community have an
indicator status of OBL, FACW or FAC, or has a prevalence index of less than 3.00 for a site to
display a positive wetland vegetation indicator.
At each sample point, plant species dominance was estimated based on the percent aerial coverage
within the community type being sampled. The sample point locations were marked in the field with
a pin flag and surveyed by Hyalite Engineers using GPS or total station survey methods and an
updated project area wetland figure is provided in Appendix A. For each wetland and upland sample
point, USACE Wetland Determination Data Forms were completed (Appendix B).
3.3 Stream Channels and other Non-Wetland Waterways
According to the Issuance and Reissuance of Nationwide Permits and Conditions [Federal Register,
January 6, 2017], “Areas where wetland vegetation is not present should be determined by the
presence or absence of an ordinary high-water mark or bed and bank”. Applying this general
guidance, natural drainage features not satisfying wetland criteria were delineated as non-wetland
waterways or channels if they exhibited a clear bed and bank/ordinary high-water mark. These
areas were typically unvegetated or supported sparse hydrophytic vegetation.
The ordinary high-water mark (OHWM) for Baxter Creek was determined in the field according to
33 CFP 328.3 (e); the term “ordinary high-water mark” is defined by the line on the shore
established by the fluctuations of water and indicated by physical characteristics such as a clear,
natural line impressed on the bank, shelfing, changes in the character of soil, destruction of

terrestrial vegetation, the presence of litter and debris or other appropriate means that consider the
characteristics of the surrounding areas. During the 2020 delineation, Baxter Creek’s OHWM was
determined to be the edge of water within the property boundary.
3.4 Wetland Classification
Sample points and wetlands were assigned unique identifiers, photographed and primarily
characterized according to the hydrogeomorphic (HGM) classification method (Smith et al., 1995)
and USFWS classification (Cowardin et al., 1979). The HGM classification is based on geomorphic
(landscape) setting, water source and hydrodynamics (Smith et al., 1995). A brief description of
each wetland type is presented below.
• Riverine wetlands occur in floodplains and riparian corridors in association with stream
channels; dominant water sources include overbank flow or subsurface hydraulic connections
between stream channels and wetlands.
• Slope wetlands occur on sloping land where groundwater is discharging to the ground
surface. Principal water sources are groundwater discharge, interflow from surrounding
uplands and precipitation.
• Depression wetlands occur in topographic depressions that allow the accumulation of
surface water and may be closed basins or may have outlets and/or inlets. For depression
wetlands, dominant water sources are precipitation, high groundwater, groundwater
discharge and interflow from adjacent uplands (Smith et al., 1995).
3.5 Guidance Used in Preliminary Jurisdictional Determinations
Wetlands were identified as those areas exhibiting wetland hydrology, hydric soils and a dominance
of hydrophytic vegetation. All such areas (wetlands and waterways) encountered in the project area
were delineated, regardless of their preliminary jurisdictional status. Generally, wetlands and
waterways are followed down-gradient until they physically join with a known WOTUS, join with a
continuous tributary to a known WOTUS or end in an upland. Due to the restrains of an urban
setting, the Baxter Creek channel was followed using online resources including the Gallatin
Conservation District stream and ditch map, Google Earth, National Wetland Inventory (NWI),
Gallatin County Soil Survey and high-res images (LandViewer).
Wetlands were classified as “likely jurisdictional” if they were contiguous or adjacent as defined in
Section 2.3 with a known WOTUS or a perennial, intermittent tributary to a known WOTUS.
4.0 RESULTS
A detailed description of the delineated wetlands and sample points are provided in the following
section. Representative photographs of the wetlands, Baxter Creek and sample points are labeled
and included in Appendix C.
4.1 Delineated Wetlands
Within the property, two wetlands (WL-1 and WL-2) covering 5.00 acres were delineated on
September 4th and 7th, 2020 along both sides of Baxter Creek and the eastern side of the ditch. The
delineated wetlands and Baxter Creek are shown on Figure 1 of 1, Appendix A. The classification,

Wetlands and Other Waters of the U.S. Delineation Report October 2020

acreage, comments on connectivity, jurisdictional status and a narrative description are summarized
for the wetland and Baxter Creek (Table 1). Wetland determination data forms were completed for
the wetlands and corresponding uplands and are included in Appendix B.
4.1.1 Wetland Boundaries
Wetland boundary determinations were challenging at times due to the abundance of creeping
meadow-foxtail (Alopecurus arundinaceus, FAC) and field meadow-foxtail (Alopecurus pratensis,
FAC) in both wetland and upland sample plots. Transects were established for additional subsurface
exploration to assess soils and hydrology along the north end of the project area, across the west side
of the creek and on the east side of the creek (northeast corner). Four 100-foot transects, located
perpendicular across the areas in question, were used to examine soils and hydrology. Pin flags were
used to mark upland and wetland soil pits along the transects to help guide wetland boundaries.
Although most of the pin flags were removed following the boundary sampling, several were used as
representative sample data points. In other areas, topographic breaks were used to help identify
wetland boundaries in depressional areas due to historic channel straightening, old stream terraces
and along the relatively narrow drainage ditch along the north side of the property. Shifts in plant
species composition toward drier species such as smooth brome (Bromus inermis, FACU) assisted
with boundary determinations.
4.2 Hydrology
Overall, the key primary wetland hydrology indicator observed throughout all areas identified as
wetlands was saturation within the upper 12 inches (see completed data forms in Appendix B).
Observations of surface flow, an OHWM and a well-defined bed and bank characterize Baxter
Creek. Most of the wetlands within the project area are sourced by seasonally high groundwater and
wetlands bordering or adjacent to Baxter Creek are seasonally/temporarily flooded where surface
water may be present for a brief time during spring runoff.
There is an excavated, straight irrigation ditch that flows immediately west of the western property
boundary fence; this ditch and seasonally high groundwater provide the hydrology for WL-1.
Surface water was noted in the ditch until it reaches Fallon Street, where the water diffuses and the
channel to the east is poorly defined. There was not a visible surface water connection from the ditch
to Baxter Creek. Surface water accumulates along the northwest portion of WL-2 in low areas near
Fallon Street where dense stands of reed canary grass (Phalaris arundinacea, FACW) are present.
These depressional wetlands appear to receive hydrologic input from seasonal high groundwater and
site disturbance associated with the historic Fallon Street road construction may have created some
artificial hydrology resulting in ponded water.
4.3 Soils
The NRCS has identified two mapped units or soil types within the delineation area. Generally, each
map unit is typically composed of one or more soil types and NRCS has rated the percentage of each
soil type that meets the criteria for hydric soils. Listed below are the soil types and hydric ratings
(percentage) for the soil types; a more detailed description of each soil type and location are provided
in Appendix D. This report describes the soil types mapped within the delineation boundaries as
described below:
Baxter Creek Commercial Property
Wetlands and Other Waters of the U.S. Delineation Report October 2020
8
• 510B - Meadowcreek loam is a deep soil found along stream terraces with slopes ranging
from 0 to 4 percent (10 percent hydric soils).
• 537A – Lamoose silt loam is a relatively deep soil found on stream terraces with slopes
ranging from 0 to 2 percent (95 percent hydric soils).
Detailed soil descriptions for the delineated wetland (and corresponding uplands) are provided on
the delineation data forms in Appendix B. In general, the wetland soils are predominantly a loam,
silt loam or clay loam with matrix hues of 10YR, 7.5YR or 5YR, matrix values of 2 to 4 and matrix
chroma of 2 or less. Redoximorphic concentrations were common throughout the wetland soils
throughout the project area. Hydric soil indicators were generally a depleted matrix (F3) or a redox
dark surface (F6).
4.4 Vegetation
The dominant plant species found in the wetland and upland areas are described in Section 4.4.1,
4.4.2 and 4.2, respectfully, and are provided on the delineation data forms in Appendix B.
4.4.1 Palustrine Emergent Wetland (PEM) – Wetland 1
Wetland 1 (WL-1) comprises approximately 0.63 acres of palustrine emergent wetlands located
along the southwest corner of the property. WL-1 is a depression wetland occupying a low area
adjacent to a drainage or irrigation ditch that parallels the west side of the property boundary fence.
Surface water was observed within the excavated straight ditch that extends from Huffine Lane to
Fallon Street. WL-1 is supported by seasonal high groundwater and the irrigation ditch. An
upgradient surface water source south of Huffine was not evident for WL-1 except for a small
depression at the ditch culvert inlet. Wetland hydrology was confirmed by the presence of primary
indicators including saturated soils. In addition, there was flowing water in the ditch along the
western property fence which may also be contributing to the wetland hydrology.
The wetland soils are predominantly a very dark brown or very dark grayish brown loam in the upper
soil profile grading to a very dark gray clay loam with depth. Strong brown redoximorphic
concentrations were noted at 8 inches below the ground surface at both sample plots. Hydric soil
indicators were a redox dark surface (F6). Dominant vegetation included spreading bentgrass
(Agrostis alba, FAC), field horsetail (Equisetum arvense, FAC), field meadow foxtail and reed
canary grass.
4.4.2 Palustrine Emergent and Excavated Wetlands (PEM, PEMx) – Wetland 2
Wetland 2 (WL-2) represents approximately 4.37 acres of palustrine emergent wetlands adjacent to
Baxter Creek and comprises riverine, slope and depressional wetlands that border the creek in
addition to concave areas within the floodplain and areas associated with excavation of the
straightened channel. Wetland hydrology was confirmed by the presence of primary indicators
including areas of saturated soils and ponded surface water. Most of WL-2 receives hydrology from
Baxter Creek where both water surface and groundwater elevations are influenced by groundwater,
which is typically the highest during spring runoff and historically after upgradient summer irrigation
has been terminated. Additional hydrology sources include flows from the irrigation ditch and

Wetlands and Other Waters of the U.S. Delineation Report October 2020

seasonal high groundwater. Depressional wetlands or swales located some distance from the creek
are likely historic oxbows or the old channels that are also supported by seasonal high groundwater.
The wetland soils were variable within WL-2 and ranged from a very dark gray or a very dark brown
silt loam to a black silt loam, some with inclusions of sand or organic soil as noted within the old
creek channel or the old ditch channel that borders the northeast corner of the property. Strong
brown redoximorphic concentrations were noted between 5 and 8 inches below the ground surface at
all sample plots. Hydric soil indicators were a redox dark surface (F6) or a depleted matrix (F3).
Dominant vegetation within WL-2 varied depending on proximity to the creek with species such as
northwest territory sedge (Carex utriculata, OBL) generally found in wetter areas immediately
adjacent to the water. Reed canary grass, meadow-foxtail, Baltic rush (Juncus balticus, FACW)
and/or slender sedge (Carex athrostachya, FACW) typically dominated wetland transition areas.
Creeping meadow-foxtail was common in wetland areas and at many upland sample points, but
wetland soils and hydrology were lacking at the upland sample points.
4.5 Uplands
A total of eleven (11) upland sample points (SPU’s) were completed for the project area and are
included in Appendix B. These sampling points were used to assist in establishing wetland
boundaries and to determine/verify upland areas. Taken throughout the project area, these sample
points represent typical uplands in the area. Uplands areas generally occurred in slightly higher
topography or as an upland inclusion within a wetland. The upland sample point vegetation included
a mix of hydrophytic and upland vegetation; several of the upland sample points have a dominance
of hydrophytic vegetation but lacked hydric soils or wetland hydrology. Upland vegetation
commonly included a dominance of smooth brome, creeping meadow-foxtail, reed canary grass,
creeping wild rye (Elymus repens, FAC) and/or field sow-thistle (Sonchus arvense, FACU). Species
such as creeping meadow-foxtail, field meadow-foxtail and reed canary grass, once established, can
persist in droughty soils. These species can extract sufficient groundwater to sustain growth even
when the conditions for a wetland environment are not present and can result in upland areas with
hydrophytic species present where wetlands, irrigation or old channels/ditches may have previously
existed.
Reed canary grass is common on anthropogenically altered sites such as ditches, agricultural fields
that are under cultivation or abandoned sites near water impoundment structures (e.g., dams, levees),
disturbed wetlands and along highways and roads. It also establishes on sites where disturbance has
occurred, such as abandoned agricultural fields. Both creeping meadow-foxtail and field meadow-
foxtail are considered aggressive, rhizomatous grasses that spread quickly from wind-borne seeds
and spreading roots. “Garrison” creeping foxtail is a commonly seeded, pasture or forage grass on
sub-irrigated or irrigated fields and once established, can persist after irrigation has ceased or
groundwater conditions change.
Proximity of groundwater to the soil surface affects vegetation in two ways. If the groundwater
capillary fringe is below the root zone, plants need to extract water from the amounts naturally stored
in the soil system and this condition is characteristic of an “upland”. At the other extreme, anoxic
conditions may develop when the water table is within the root zone during at least some, if not all,
of the growing season. The chemical changes that take place in submerged soils require specific
Baxter Creek Commercial Property
Wetlands and Other Waters of the U.S. Delineation Report October 2020
10
adaptations for plants to survive and these areas are referred to as “wetlands”. Intermediate
conditions, that are expected to dominate portions of the floodplain, occur in areas where water is
available from the capillary fringe, but groundwater is deep enough that anoxic conditions are absent
from the root zone. These areas are referred to as “sub-irrigated”.

4.6 National Wetland Inventory (NWI)
The US Fish and Wildlife Service (USFWS) NWI identified two wetland types within the project
area:
• PEM1A – Palustrine, Emergent, Persistent, Temporarily Flooded
• PEM1C – Palustrine, Emergent, Persistent, Seasonally Flooded
The locations of the delineated wetlands are identified on the wetland figure in Appendix A.
In general, both wetland types identified by the NWI were confirmed during the site investigations.
However, the NWI did not show the depressional wetland (WL-1) in the southwest corner of the
property or the floodplain wetlands (WL-2), the wetland border along Baxter Creek, the old ditch and
the depressional wetlands along the northeast portion of the property (WL-2). During the September
delineation, the documentation of numerous sample points confirmed upland/wetland boundaries
that exist in areas not mapped by the NWI or confirmed different wetland classes including the creek.
5.0 SUMMARY
As outlined in Section 2.0, USACE will assert jurisdiction over traditional navigable waters, which
include all the waters described in 33 CFR 328.3 (a) (1) and 40 CFR 230.3 (s) (1). Based on
observations made at the site of surface connection to regulated waters, Wetlands 1 and 2 and the
Baxter Creek channel would be considered jurisdictional and regulated by USACE. The delineated
wetlands meet the jurisdictional definition of a wetland as defined in 33 CFR 328.3 (7) and the
Baxter Creek channel meets the USACE jurisdictional definition of a WOTUS as defined by 33 CFR
328.3(5).
Two likely jurisdictional wetlands and one jurisdictional waterway, totaling 5.00 acres of wetlands
and 944 linear feet of WOTUS, were delineated within the project area.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/
portal/nrcs/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous
areas in a specific area. They include a description of the soils and miscellaneous
areas and their location on the landscape and tables that show soil properties and
limitations affecting various uses. Soil scientists observed the steepness, length,
and shape of the slopes; the general pattern of drainage; the kinds of crops and
native plants; and the kinds of bedrock. They observed and described many soil
profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The
profile extends from the surface down into the unconsolidated material in which the
soil formed or from the surface down to bedrock. The unconsolidated material is
devoid of roots and other living organisms and has not been changed by other
biological activity.
Currently, soils are mapped according to the boundaries of major land resource
areas (MLRAs). MLRAs are geographically associated land resource units that
share common characteristics related to physiography, geology, climate, water
resources, soils, biological resources, and land uses (USDA, 2006). Soil survey
areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that
is related to the geology, landforms, relief, climate, and natural vegetation of the
area. Each kind of soil and miscellaneous area is associated with a particular kind
of landform or with a segment of the landform. By observing the soils and
miscellaneous areas in the survey area and relating their position to specific
segments of the landform, a soil scientist develops a concept, or model, of how they
were formed. Thus, during mapping, this model enables the soil scientist to predict
with a considerable degree of accuracy the kind of soil or miscellaneous area at a
specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented
by an understanding of the soil-vegetation-landscape relationship, are sufficient to
verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them
to identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character
of soil properties and the arrangement of horizons within the profile. After the soil
5
scientists classified and named the soils in the survey area, they compared the
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that
have similar use and management requirements. Each map unit is defined by a
unique combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components
of the map unit. The presence of minor components in a map unit in no way
diminishes the usefulness or accuracy of the data. The delineation of such
landforms and landform segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, onsite
investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape,
and experience of the soil scientist. Observations are made to test and refine the
soil-landscape model and predictions and to verify the classification of the soils at
specific locations. Once the soil-landscape model is refined, a significantly smaller
number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color,
depth to bedrock, and texture, and laboratory measurements, such as those for
content of sand, silt, clay, salt, and other components. Properties of each soil
typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists
interpret the data from these analyses and tests as well as the field-observed
characteristics and the soil properties to determine the expected behavior of the
soils under different uses. Interpretations for all of the soils are field tested through
observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new
interpretations are developed to meet local needs. Data are assembled from other
sources, such as research information, production records, and field experience of
specialists. For example, data on crop yields under defined levels of management
are assembled from farm records and from field or plot experiments on the same
kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on
such variables as climate and biological activity. Soil conditions are predictable over
long periods of time, but they are not predictable from year to year. For example,
soil scientists can predict with a fairly high degree of accuracy that a given soil will
have a high water table within certain depths in most years, but they cannot predict
that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions (Baxter Creek
Commercial Property)
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
Custom Soil Resource Report
11
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.

Soil Information for All Uses
Suitabilities and Limitations for Use
The Suitabilities and Limitations for Use section includes various soil interpretations
displayed as thematic maps with a summary table for the soil map units in the
selected area of interest. A single value or rating for each map unit is generated by
aggregating the interpretive ratings of individual map unit components. This
aggregation process is defined for each interpretation.
Land Classifications
Land Classifications are specified land use and management groupings that are
assigned to soil areas because combinations of soil have similar behavior for
specified practices. Most are based on soil properties and other factors that directly
influence the specific use of the soil. Example classifications include ecological site
classification, farmland classification, irrigated and nonirrigated land capability
classification, and hydric rating.
Hydric Rating by Map Unit (Baxter Creek Commercial
Property)
This rating indicates the percentage of map units that meets the criteria for hydric
soils. Map units are composed of one or more map unit components or soil types,
each of which is rated as hydric soil or not hydric. Map units that are made up
dominantly of hydric soils may have small areas of minor nonhydric components in
the higher positions on the landform, and map units that are made up dominantly of
nonhydric soils may have small areas of minor hydric components in the lower
positions on the landform. Each map unit is rated based on its respective
components and the percentage of each component within the map unit.
The thematic map is color coded based on the composition of hydric components.
The five color classes are separated as 100 percent hydric components, 66 to 99
percent hydric components, 33 to 65 percent hydric components, 1 to 32 percent
hydric components, and less than one percent hydric components.
16
In Web Soil Survey, the Summary by Map Unit table that is displayed below the
map pane contains a column named 'Rating'. In this column the percentage of each
map unit that is classified as hydric is displayed.
Hydric soils are defined by the National Technical Committee for Hydric Soils
(NTCHS) as soils that formed under conditions of saturation, flooding, or ponding
long enough during the growing season to develop anaerobic conditions in the
upper part (Federal Register, 1994). Under natural conditions, these soils are either
saturated or inundated long enough during the growing season to support the
growth and reproduction of hydrophytic vegetation.
The NTCHS definition identifies general soil properties that are associated with
wetness. In order to determine whether a specific soil is a hydric soil or nonhydric
soil, however, more specific information, such as information about the depth and
duration of the water table, is needed. Thus, criteria that identify those estimated
soil properties unique to hydric soils have been established (Federal Register,
2002). These criteria are used to identify map unit components that normally are
associated with wetlands. The criteria used are selected estimated soil properties
that are described in "Soil Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil
Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey
Division Staff, 1993).
If soils are wet enough for a long enough period of time to be considered hydric,
they should exhibit certain properties that can be easily observed in the field. These
visible properties are indicators of hydric soils. The indicators used to make onsite
determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the
United States" (Hurt and Vasilas, 2006).
