1.0 PROJECT BACKGROUND
An investigation to identify waters of the United States (WUS) on undeveloped land
located north of Baxter Meadows Subdivision was completed by Vaughn Environmental
Services, Inc. on August 5 and 6, 2013. The parcel, owned by Mr. and Mrs. Tracy, is located
north of Kimberwicke Street, east of Ferguson Avenue, and west of Davis Lane in Bozeman,
Montana. The land is located within Tract 2A of COS No 2202C, in the southeast quarter of
Section 34, Township 1 South, Range 5 East, in Gallatin County (Figure 1.0 – USGS 7.5’
Bozeman Quadrangle Topographic Map and Figure 2.0 – Aerial Photograph). The wetland
boundaries were flagged based on vegetation, soil, and hydrological data collected during the
field investigation. The flagged boundaries of the WUS within the study area were surveyed and
mapped by Alpine Surveying, Inc. of Bozeman. The map of the project WUS was drafted by
Madison Engineering, Inc. (Figure A).
The field investigation was completed for the landowners and Madison Engineering to
identify the location, extent, and characteristics of jurisdictional WUS within the study area
boundaries for United States Army Corps of Engineers (USACE) permit compliance. The
USACE requires a permit for the discharge of fill material into WUS in accordance with Section
404 of the Clean Water Act (CWA 1986). A Supreme Court 2001 decision in the case of the
Solid Waste Agency of Northern Cook County versus US Army Corps of Engineers (SWANCC)
limited the federal authority under the Clean Water act to regulate certain isolated wetlands. In
light of the Court’s decision, WUS as it applies to the jurisdictional limits of the authority of the
USACE include the area below the ordinary high water mark (OHWM) of stream channels and
lakes or ponds connected to the tributary system, and wetlands adjacent to these waters. The
jurisdictional status of wetlands depends on the presence or absence of a connection and/or
proximity (meaning bordering, contiguous, or neighboring) to waters of the US.
A delineation of waters of the US was completed on this property prior to 2002 as part of
the larger Baxter Meadows Development (BMD). The subdivision was obtained by First
Interstate Bank in 2010. An Individual Permit (Corps File Number 2002-90-091) authorizing
impacts to project wetlands was issued to BMD by the USACE on August 20, 2002. The 404
permit expired on August 20, 2009. Project background information was extrapolated from the
Wetland Mitigation Monitoring Final Report: Year 2010 completed in June 2011 by Atkins
Global for First Interstate Bank. The land north of Kimberwicke Street was never developed by
BMD. Approximately 2.89 acres had been impacted for the subdivision development by the
permit expiration date. As of November 2010, 3.88 acres of wetland creation, restoration, and
enhancement had been constructed. Several wetland areas within the original subdivision
boundaries were expanded or enhanced for compensatory mitigation. The delineation results
detailed in this 2013 report define historic wetlands and mitigation wetlands constructed between
2002 and 2004.
The 2013 report documents the project background, methodology used to identify the
project WUS, and findings of the field investigation. Wetland Determination Data Forms
recording data collected at each sample plot are included in Appendix A. Soil mapping
information for the site is included in Appendix B and photos of the site are included in Appendix
C. Figure A in Appendix D shows the boundaries of project WUS including wetlands and the
Spring Ditch. The report will be submitted with a Joint Application for Proposed Work in
Montana’s Steams, Wetlands, Floodplain and other Water Bodies to the Helena Regulatory
Branch of the USACE as part of the 404 permit process for future development.
The study area is undeveloped except for two gravel roads, several acres of constructed
Waters of the US Delineation Report – Tracy – COS 2202C 2
mitigation wetlands, and a stormwater pond and ditch. The land north of the project site is
agricultural used for hay cultivation and livestock pasture. The land east of Davis Lane is
residential. Baxter Meadows Subdivision borders the south and west property boundaries. The
new Hyalite Elementary School is located west of the project parcel. The USDA/NRCS Official
Series Description and Web Soil Survey website (2013) for the Enbar series (509) classifies the
historic project landforms as floodplains, drainage ways, and stream terraces developed from
loam alluvium and mixed rock sources on 0 to 15 percent slopes (Appendix B).
1.1 SITE WATERWAYS
The Spring Ditch diverges from the Farmer’s Canal approximately 2.25 miles south of
the project site according to the US Geographical Survey (USGS) topographic map (Figure 1.0).
The stream discharges to the East Gallatin River approximately 4.0 miles north of the site. The
woody vegetation associated with the creek was enhanced in 2005 with willow cuttings and
containerized woody species as part of mitigation for the Baxter Meadows 404 permit. The
wetland fringe on the creek was widened and planted with a wetland seed mix and wetland
tubelings in 2005. The creek was flowing during the investigation with water depths ranging
from 0.5 foot to 1.0 foot. The stream channel was 2.0 to 3.0 feet wide with bank heights of 1.0 to
1.5 feet.
The Section Line Ditch was relocated to the east side of Davis Lane for road and
subdivision development. The ditch channel is routed to the northeast corner of the project
through a culvert (Figure A). The channel is diverted through a second culvert under the gravel
road located near the north boundary. The ditch parallels the gravel road then turns north to the
borrow ditch located on the west side of Davis Lane. The historic source was the Farmer’s Canal
located approximately two miles south of the site. The ditch ultimately discharges to the East
Gallatin River. The ditch channel did not contain surface water during the September 2013
investigation.
1.2 CLIMATE
The Bozeman area climate generally resembles that of a middle latitude steppe, with
relatively long cold winters and short cool summers (Pac 1991). The region comprises a
mountain complex within the steppe region, resulting in orographic effects that produce a local,
cooler and wetter climate. Peak runoff generally occurs during the spring from snowmelt and
combined snowmelt/rainfall events. These events produce relatively long periods of runoff.
Summer thunderstorms also contribute to peak runoff although they are generally short in
duration. The annual pattern of precipitation typically results in increasing precipitation from
March to a peak in June, a decline through mid summer, another increase in late August to a
second, smaller peak in September, followed by a general decline to the yearly low in February
(Pac et al 1993). The annual temperature regime of the study area is generally characterized by
significant seasonal variations. Winters are typically long and cold with subfreezing average
temperatures from November to March. Average annual precipitation ranges from 13 inches per
year at the lower elevations to 50 inches per year at the higher elevations in the Bridger Range
north of Bozeman (NRCS 1972). Although the average annual precipitation is low enough to
classify most of the area as semi-arid, about 70 percent of the annual total precipitation normally
falls during the April to September growing season.
Elevations in the study area range from 4,701 feet to 4,713 feet above mean sea level
(amsl). The closest meteorological station to the study area is Montana State University located
approximately 3.5 miles southeast of the project at 4,860 feet (amsl). Records from 1961 to 1990
Waters of the US Delineation Report – Tracy – COS 2202C 3
indicate that the average annual precipitation is 19.25 inches with an average total snowfall of
92.1 inches. The average temperature is 44.2 degrees Fahrenheit (USDA 1990). The mean
annual precipitation rate for the predominant soil map unit, the Enbar loam (509B), is 14 to 22
inches.

2.0 WETLAND DELINEATION METHODS
2.1 METHODS
Waters of the US including jurisdictional wetlands within the study area were identified
on August 5 and 6, 2013, using methodology developed by the USACE and other federal
agencies for implementation of Section 404 of the CWA. Delineation procedures involved a
review of existing site-specific information and completion of an onsite field investigation based
on guidelines for the Routine Determination Method presented in the Field Guide for Wetland
Delineation (Environmental Laboratory 1987) and Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (USACE
2010).
The Routine Level-2 Onsite Determination Method employs primarily qualitative
procedures. Sample plots (approximately a 5-foot radius in emergent wetlands) are established
within potential wetlands based on changes in plant communities, plant diversity, topography,
and soil type. Data points are generally located parallel to watercourses, perpendicular to the
apparent groundwater hydraulic gradient, and/or along topographical breaks. Vegetation
composition, hydrology, and soil characteristics are assessed at each data collection point. If all
three parameters exhibit positive wetland indictors, the area represented by the sample plot is
classified as wetland. If any one of the parameters does not display a positive indicator, the area
is classified as a non-wetland or upland unless the wetland is atypical or problematic. The
jurisdictional authority of the USACE over wetlands identified in the field depends on the
presence or absence of a surface water connection and/or proximity to waters of the US. Separate
Wetland Determination Data Forms were completed for W-1 through W-5 and W-11. Wetlands
W-6 to W-10 were addressed on a single form. No form was completed for the stormwater pond
W-13. Test pits SP-1, SP-2, and SP-3 were excavated in W-1, W-4, and W-5 respectively. The
forms are included in Appendix A.
2.2 TECHNICAL CRITERIA
A wetland must meet three technical criteria for it to be categorized as jurisdictional. The
USACE (259 Federal Register 853532) and the Environmental Protection Agency (47 FR 31810)
jointly define wetlands as “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.” The following
conditions must be present for an area to be considered a jurisdictional wetland.
1. Hydrophytic Vegetation: Defined as plant species normally or commonly
adapted to saturation of sufficient duration to cause anaerobic conditions in the
root zone.
2. Wetland Hydrology: Defined as hydrology supported by sources of water that
result in saturated, flooded, or ponded soil conditions.
3. Hydric Soils: Defined as soil that forms under conditions of saturation, flooding,
or ponding long enough during the growing season to develop anaerobic
conditions in the upper part (59 Fed. Reg. 35680, 7/13/94).
Hydrophytic Vegetation
Plants must be physiologically or morphologically adapted to saturated or anaerobic soil
Waters of the US Delineation Report – Tracy – COS 2202C 7
conditions to grow in wetlands. The USACE and the US Fish and Wildlife Service (USFWS)
have determined the estimated probability of finding representative wetland species within
specified areas under natural conditions. Accordingly, plants may be categorized as obligate
(OBL), facultative wetland (FACW), facultative (FAC), facultative upland (FACU), or upland
(UPL) in decreasing order of moisture dependence or tolerance. Obligate species occur greater
than 99 percent of the time in a wetland. Facultative wetland species have a 67 to 99 percent
probability of occurring in a wetland. Facultative species exhibit a 34 to 67 percent probability of
occurring in a wetland. Facultative upland species have a 67 to 99 percent probability of
occurring in a non-wetland and upland species have a greater than 99 percent probability of
occurring in a non-wetland. Species with an indicator status of OBL, FACW, or FAC are
considered hydrophytic. Vegetation indicator status for this investigation was derived from the
National Wetland Plant List for the Western Mountains, Valleys, and Coast Region (Lichvar and
Kartesz 2012). Taxonomic references included Dorn 1984, Hitchcock 1971, Lackschewitz 1991,
and Lesica and Husby 2001. The name and indicator status of individual species within each
vegetation stratum was recorded on the data form in descending order of abundance (Appendix
A).
Under the dominance test introduced in the Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (USACE
2010), a sample plot is classified as having wetland vegetation if the cumulative total of the
estimated percent cover for the dominant hydrophytic species exceeds 50 percent and 50 percent
or greater of the dominant species have a hydrophytic indicator status. The Regional Supplement
also introduced the Prevalence Index, Morphological Adaptations, and Wetland Non-Vascular
plants as indicators of hydrophytic vegetation only when indicators of hydric soil and wetland
hydrology are also present.
Wetland Hydrology
Technical criteria for wetland hydrology guidelines have been established as “permanent
or periodic inundation, or soil saturation within 12 inches of the ground surface for a significant
period (usually 14 days or more or 12.5 percent of the growing season) during the growing
season” (Environmental Laboratory 1987). The minimum duration required for soil saturation is
five percent of the growing season in consecutive days. Inundation or saturation for periods less
than 5 percent of the growing season is evidence of non-wetland conditions. Systems with
continuous inundation or saturation between 5 and 12.5 percent of the growing season may or
may not be jurisdictional wetlands based on other criteria. The growing season is defined for
purposes of this report as the number of days where there is a 50 percent probability that the
minimum daily temperature is greater than or equal to 28 Fahrenheit (Environmental Laboratory
1987). The Bozeman growing season extends from May 5 to October 1 according to the WETS
Bozeman Climate data. Approximately 19 days of saturation would meet the wetland hydrology
criterion for a specific wetland.
Either direct observations of inundation or well data showing a free water surface at
depths less than 12 inches continuously for more than 5 percent of the growing season have been
used nationally to distinguish active wetland hydrology. Surface water, groundwater, direct
precipitation, and/or snowmelt may contribute to wetland hydrology. Field observations were
used to determine existing wetland hydrology. A positive indication of wetland hydrology
requires either one primary indicator or two or more secondary indicators. The Regional
Supplement for the Western Mountains area lists the primary indicators as surface water, high
water table, saturation, water marks, sediment deposits, drift deposits, algal mat or crust, iron
deposits, surface soil cracks, inundation visible on aerial imagery, sparsely vegetated concave
Waters of the US Delineation Report – Tracy – COS 2202C 8
surface, water stained leaves, salt crust, aquatic invertebrates, hydrogen sulfide odor, oxidized
rhizospheres along living roots, presence of reduced iron, recent iron reduction in tilled soils, and
stunted or stressed plants. Secondary indicators include water-stained leaves, drainage patterns,
dry-season water table, saturation visible on aerial imagery, geomorphic position, shallow
aquitard, FAC-neutral test, raised ant mounds, and frost-heave hummocks.
Hydric Soils
Soil is considered saturated when the capillary fringe occurs within a major portion of the
root zone (within 12 inches of the surface). The Natural Resource Conservation Service (NRCS),
formerly the Soil Conservation Service (SCS), in cooperation with the National Technical
Committee for Hydric Soils (NTCHS), has compiled a list of hydric soils in the United States.
The list identifies soil series mapped by the NRCS that meet the hydric criteria. Upland (non-
wetland) soils may have inclusions of hydric soils that may not be demarcated on NRCS maps.
Field examination of site-specific soil characteristics is necessary to confirm the presence of
hydric soils. The profile description presented on the data form reflects site soil conditions as
determined from soil pits, not the NRCS designation. The NRCS soil survey information
reviewed for the project area is included in Appendix B.
Hydric soils exhibit certain physical characteristics that can be observed visually. These
characteristics, or indicators, include high organic matter content (histic epipedons), accumulation
of sulfidic material, gley formation (greenish or bluish gray color), redoximorphic features
(mottling), and low soil chromas (dark soil colors – soil chroma). Organic matter content is
estimated visually and texturally; redoximorphic features are identified visually; sulfidic material
is identified by the odor of sulfide gases; and soil colors are determined using a Munsell soil color
chart (Munsell 1988). The colorimetric determination is to be made immediately below the “A”
horizon or 10 inches whichever is less. The Regional Supplement for Western Mountains
introduced new classifications for hydric soil indicators based on the soil type (organic, muck or
mineral), soil matrix, and type of redoximorphic features such as concentrations, depletions,
reduced matrix, or covered or coated sand grains. The full description of each category is
included in Chapter Three of the Regional Supplement for the Western Mountains area. Wetland
soils can be assumed to be present in any plant community where all the dominant species have
an indicator status of OBL or FACW, and the wetland boundary is abrupt (Environmental
Laboratory 1987).

3.0 WETLAND DELINEATION RESULTS
A site investigation to determine the presence and extent of waters of the US within the
study area was completed by Vaughn Environmental Services (VES) on August 5 and 6, 2013.
Alpine Engineering surveyed the demarcated boundaries using a global positioning system
(GPS). Wetland boundaries were flagged by VES based on the presence of hydrophytic
vegetation, hydric soil, and primary hydrologic indicators. Wetland types were based on
similarities in physiographic, hydrologic, and plant community characteristics. Site-specific
wetland parameters are described on the Wetland Determination Data Forms included in
Appendix A. Figure A drafted by Madison Engineering shows the boundaries of waters of the
US including wetlands within the study area (Appendix D).
Wetland 1 (W-1) is an open topographic depression wetland based on the
hydrogeomorphic classification system (Smith et al. 1995). A culvert located at the northwest
corner of the wetland drains excess surface water under the gravel road to W-9 situated at the
north property boundary. The primary source of water is groundwater and the wetland is
classified as palustrine with emergent vegetation according to the Cowardin classification system
(Cowardin et al. 1979). The west edge of the wetland was expanded as part of mitigation for
permit 2002-90-091. Wetlands W-2, W-4, W-5, W-7, W-8, and W-10 were categorized as
palustrine, depression wetlands dominated by emergent vegetation. Wetlands W-6, W-9, and W-
12 were classified as riverine based on the downgradient connection to waters of the US.
Wetland W-2, wetlands 6 to 10, and W-12 were located within the borrow ditches located on the
north and south sides of the gravel road that parallels the north boundary.
The Spring Ditch (W-3) is a perennial stream classified as a riverine, lower perennial,
wetland (Smith et al 1995) and a riverine, lower perennial, rock bottom wetland under the
Cowardin system (Cowardin et al 1979). The water regime is permanently flooded. Riverine
systems are associated with flowing water from stream channels, old oxbows, or abandoned
meanders, and creek margins. Stream channels must exhibit an ordinary high water mark
(OHWM) to be considered a WUS. The term OHWM means the line established by the
fluctuations of water as indicated by physical characteristics such as a clear, and natural line
impressed on the bank shelving, changes in the character of soil, destruction of terrestrial
vegetation, and the presence of litter and debris, (33 CFR 2003).
The Section-Line Ditch (W-11) traverses the property at the northeast corner. The ditch
segment within the project area was excavated as part of the Baxter Meadows development. The
channel was dry during the August 2013 investigation. The ditch was classified as a water of the
US. The banks of the ditch are steep and rocky and do not support hydrophytic plants except at
the base of the slopes. Water of the US W-13 is a stormwater pond connected at the
downgradient end to W-3 via a culvert and pipe. The banks of the pond are steep and rocky and
support a limited number of wetland plants at the water’s edge.
Section 3.1 discusses the Natural Resource Conservation Service (NRCS) soil survey
results for the project site. The characteristics of the project WUS are described in Sections 3.2 to
3.8. The Wetland Determination Data forms are included in Appendix A and the NRCS soil map
and soil descriptions are included in Appendix B. Photographs of W-1 to W-13 are included in
Appendix C. Appendix D contains the Waters of the US Exhibit, Figure A.
3.1 NRCS SOIL SURVEY RESULTS
The web soil survey for Gallatin County (USDA/NRCS 2012) identifies a majority of the
Waters of the US Delineation Report – Tracy – COS 2202C 10
project wetlands within the Enbar loam (509B) map unit found on 0 to 4 percent slopes
(Appendix B). Wetland W-1 was mapped within the Blossberg loam found on 0 to 2 percent
slopes. The Enbar series are very deep, somewhat poorly drained soils. They are taxonomically
classified as fine-loamy, mixed, superactive, frigid Cumulic Haplustolls. The typical land use is
for pasture, hay, and rangeland. The Blossberg series are very deep, poorly drained soils found
on floodplains, depressions, drainageways, alluvial fans, and stream terraces. The taxonomic
class is fine-loamy over sandy or sandy-skeletal, mixed, superactive, frigid Typic Endoaquolls.
The Blossberg series are classified as hydric based on the taxonomy.
3.2 W-1 – DEPRESSION, PALUSTRINE, EMERGENT WETLAND
Wetland 1 (W-1) is a 10.77 acre historic wetland located in the northeast corner of the
parcel. Fifty to one hundred feet of the west and south edges of the wetland were excavated in
spring 2005 to create additional wetland for mitigation credit. The excavated area and adjacent
existing wetland were planted with trees and shrubs to enhance the structural diversity. The water
regime is seasonal/intermittent. Soil test pit 1 (SP-1) was located in the northwest corner of W-1.
Vegetation
Herbaceous species dominated W-1 (Photo 1). The predominant species identified within
a 5-foot radius of SP-1 were common spikerush (Eleocharis palustris – OBL), round-fruit rush
(Juncus compressus – OBL), American wild mint (Mentha arvensis – FACW), broad leaf cattail
(Typha latifolia – OBL), long-style rush (Juncus longistylis – FACW), and lesser poverty rush
(Juncus tenuis – FAC) (Photo 2). The dominant species were 100 percent hydrophytic.
Additional species observed were lamp rush (Juncus effusus – FACW), spreading bentgrass
(Agrostis stolonifera – FAC), toad rush (Juncus bufonius – FACW), Nebraska sedge (Carex
nebrascensis – OBL), tufted hairgrass (Deschampsia caespitosa – FACW), Pacific willow (Salix
lasiandra – FACW), narrow leaf willow (Salix exigua – FACW), Bebb willow (Salix bebbiana –
FACW), and red-osier dogwood (Cornus alba – FACW). A large stand of Canadian thistle
(Cirsium arvense – FAC) was observed at the center of the wetland. Several Russian olive
(Elaeagnus angustifolia – FAC) shrubs have invaded the west edge of the wetland.
The northeast corner of W-1 is vegetated with shrub-scrub species dominated by Bebb
and sandbar willow. The wetland was planted with 184, 1- to 10-gallon containerized woody
species and 550 wetland tubelings..
Soil
The soil profile from 0 to 19 inches in SP-1 revealed a black silt clay loam (10 YR 2/1)
with 2 percent or less faint dark yellowish brown (10 YR 4/6) redoximorphic features. The pit
was located within the Blossberg loam (542A) hydric map unit. The redox dark surface was an
indication of a hydric soil.
Hydrology
Surface water and saturation were not observed in test pit SP-1. An algal mat, surface
soil cracks, and a sparsely vegetated concave surface provided primary indicators of wetland
hydrology. Ponded surface water was evident in the nearby borrow ditches at less than 2.0 feet
below the ground surface.
3.3 W-2 – DEPRESSION, PALUSTRINE, EMERGENT WETLAND
Wetland 2 (W-2) is a small, closed depression located within the borrow ditch on the
Waters of the US Delineation Report – Tracy – COS 2202C 11
south side of the gravel road, east of the pump house, and west of W-1. No test pit was excavated
based on the presence of surface water on the ground surface and the predominance of obligate
and facultative wetland species. Wetland 2 (W-2) is connected to W-3 via a 12-inch concrete
culvert.
Vegetation
Herbaceous and shrub-scrub species dominate W-2 (Photo 3). The primary species are
balsam poplar (Populus balsamifera – FAC), narrow leaf willow, broad leaf cattail, round-fruit
rush, American wild mint, lesser poverty rush, and common silver weed (Argentina anserina –
OBL). The dominant species are 100 percent hydrophytic.
Soil
No test pit was excavated. The borrow ditch lies within the Enbar loam map unit.
Hydrology
Surface water was observed on the ground surface at the base of the borrow ditch. An
algal mat and surface soil cracks were additional primary indicators of wetland hydrology.
Drainage patterns and geomorphic position were secondary indicators of wetland hydrology.
3.4 W-3 – SPRING DITCH – RIVERINE WETLAND, LOWER PERENNIAL,
ROCK BOTTOM; EMERGENT AND SHRUB-SCRUB VEGETATION
Wetland 3 (W-3) is a large 4.8 acre wetland complex that extends from the south to north
property boundary across the center of the parcel. The complex encompasses the Spring Ditch, a
borrow ditch, adjacent floodplain wetlands, and two stormwater ponds and an open stormwater
channel. The northeast side of the wetland starts in the borrow ditch located on the south side of
the gravel road, west of the pump house. The borrow ditch contained ponded surface water. The
Spring Ditch is diverted through an arched concrete culvert across the gravel road at the north
boundary and at Kimberwicke Street on the south boundary of the parcel. The Spring Ditch is
classified as a perennial stream. The creek was flowing during the investigation. The channel
ranges in width from 4.0 to 6.0 feet with bank heights from 0.5 to 1.5 feet. The surface water
depth varies from 0.5 to 1.0 foot.
Vegetation
Herbaceous species dominate a majority of W-3 (Photos 4 to 8). The south reach of the
creek within the parcel exhibits a shrub-scrub class dominated by a variety of willows and balsam
poplar. The dominant species identified within the complex were broad leaf cattail, Northwest
Territory sedge (Carex utriculata – OBL), Nebraska sedge, spreading bent grass, fringed willow
herb (Epilobium ciliatum – FACW), Bebb willow, and sandbar willow. The dominant species are
100 percent hydrophytic.
Additional species observed included seep monkey flower (Mimulus guttata – OBL), red-
tinge bulrush (Scirpus microcarpus – OBL), three-square club rush (Schoenoplectus pungens -
OBL), hard stem club rush (Schoenoplectus acutus – OBL), American brooklime (Veronica
americana – OBL), knotted rush (Juncus nodosus – OBL), American mannagrass (Glyceria
grandis – OBL), large-leaf avens (Geum macrophyllum – FAC), common duckweed (Lemna
minor – OBL), balsam cottonwood, and quaking aspen (Populus tremuloides – FACU).
Canadian thistle dominates the upland berms around the perimeter of the complex. The
mitigation areas created adjacent to Spring Ditch north of Baxter Lane were planted with 508, 1-
Waters of the US Delineation Report – Tracy – COS 2202C 12
to 5-gallon woody trees and shrubs and willow cuttings and 450 wetland tubelings. The plant list
is included in Appendix E.
Soil
No test pits was excavated within W-3 based on the dominance of surface water and
presence of obligate and facultative wet species. The complex is mapped within the Enbar loam
map unit. The 2008 test pit excavated within the complex revealed gleyed clay soil at 10 inches
bgs with greater than 5 percent yellowish brown (10 YR 4/6) redoximorphic features. The loamy
gleyed matrix provided an indication of hydric soil.
Hydrology
Surface water inundation was observed in Spring Ditch and throughout the complex.
Surface water depths ranged from 1 to 12 inches. Water marks, algal mat, surface soil cracks,
inundation visible on aerial imagery, hydrogen sulfide odor, drainage patterns, and geomorphic
position provided positive indicators of wetland hydrology.
3.5 W-4 – DEPRESSION, PALUSTRINE, EMERGENT WETLAND
Wetland 4 (W-4) is a depression wetland dominated by emergent vegetation located
south of the gravel road and west of W-3. Narrow leaf and Bebb willows line the constructed
berm located at the southwest boundary of the wetland. There is no outlet or culvert at the
downgradient end of the wetland.
Vegetation
Herbaceous species dominate W-4 (cover photo and Photo 9). Common spike rush,
broad leaf cattail, round fruit rush, and Nebraska sedge dominated the species. One hundred
percent of the dominant species were hydrophytic. Test pit SP-2 was located within the northeast
quadrant of the wetland.
Soil
Test pit SP-2 was excavated to 16 inches below the ground surface. The soil profile
revealed a black silt loam (10 YR 2/1) with less than 2 percent with faint yellowish brown (10 YR
4/6) redoximorphic concentrations in the soil matrix. The redox dark surface provided an
indication of a hydric soil.
Hydrology
Algal mats, surface soil cracks, and a sparsely vegetated concave surface provided
evidence of wetland hydrology No surface water, groundwater table, or saturation were observed
within the test pit.
3.6 W-5 – DEPRESSION, PALUSTRINE, EMERGENT WETLAND
Wetland W-5 is a depression wetland dominated by emergent vegetation located in the
floodplain west of W-3. Test pit SP-3 was located near the northwest edge of the wetland (Photo
10). The wetland was constructed for mitigation based on the presence of construction stakes and
silt fence. Wetland W-5 lies between the Spring Ditch and a stormwater pond. The area was
classified as a wetland although there was no clear evidence of hydric soil. This may have been
the result of the wetland being recently constructed.
Waters of the US Delineation Report – Tracy – COS 2202C 13
Vegetation
The vegetation species were dominated by beaked sedge, Nebraska sedge, long-style
rush, and Sierran rush (Juncus nevadensis – FACW). All of the dominant species were
hydrophytic. Additional species include tufted hairgrass and spreading bentgrass. Stands of
Canadian thistle proliferate throughout the upland areas between the wetlands.
Soil
Test pit SP-3 was excavated to 18 inches below the ground surface. The soil profile
revealed a black silt loam (10 YR 2/1) without redoximorphc features. Although the soil
exhibited a dark chroma, the criteria for a redox dark surface requires the presence of redox
features. The lack of redox features may be the result of recent construction.
Hydrology
Algal mats, surface soil cracks, and frost-heave hummocks provided evidence of wetland
hydrology No surface water, groundwater table, or saturation were observed within the test pit.
3.7 W-6, W-7, W- 8, W-9, W-10, and W-12 – DEPRESSION, PALUSTRINE,
EMERGENT WETLANDS WITHIN BORROW DITCH ON NORTH SIDE OF
GRAVEL ROAD
The east/west gravel road located near the north property boundary has created a barrier
to ground water and surface water resulting in the development of wetland conditions in several
low depressions located on the north side of the road. Wetland 6 (W-6) is located at the culvert
outlet that extends under the gravel road from the west edge of W-3 (Photo 11). A small channel
continues to flow north from the outlet across the adjacent property. Wetlands W-7 and W-8 are
closed, isolated depressions surrounded by upland (Photos 12 and 13). Wetland W-9 has formed
at the culvert outlet from W-1 (Photo 14). A second channel continues north on to the adjacent
property from the culvert outlet at W-9. Wetland W-10 has formed at the edge of the fenced
boundary north of the gravel road near the northeast boundary (Photo 15). The wetland extends
across the north property boundary. Wetland 12 (W-12) is located at the outfall from a rusted
barrel less than 12 feet west of the concrete arched culvert for the Spring Ditch (Photo 18). The
surface water flows to the channel that forms at the culvert outlet on the north property boundary.
Vegetation
The following vegetation species were predominant in W-7. All the borrow ditches
contained the same species although in varying cover percentages. The herbaceous species
included Nebraska sedge, beaked sedge, broad leaf cattail, round fruit rush, spreading bentgrass,
and meadow foxtail. Additional species observed in borrow ditches included Bebb willow, curly
dock, common duckweed, lesser poverty rush, long-style rush, American mannagrass, and
common tansy (Tanacetum vulgare – FACU).
Soil
No test pit was excavated. The plants were dominated by obligate and facultative
wetland species. There was no surface water in W-7 or W-8 although it was present at W-6, W-9,
W-10, and W-12.
Hydrology
Algal mats, surface soil cracks, and geomorphic position provided evidence of wetland
Waters of the US Delineation Report – Tracy – COS 2202C 14
hydrology. Ponded surface water 2 to 6 inches deep was present at the culvert outlets at W-6, W-
9, and W-12.
3.8 W-11 – SECTION LINE DITCH – WATER OF THE US
The Section Line Ditch was relocated to the east side of Davis Lane for construction of
the road. Surface water flow in the ditch is diverted through a culvert across Davis Lane to a
constructed channel located in the northeast corner of the parcel (Photos 16 and 17). The channel
bed is lined with large rock. There is a narrow, intermittent wetland fringe at the base of the
channel. Flow in the channel is diverted though another culvert under the gravel road to a heavily
armored channel located on the north side of the gravel road. The ditch channel did not contain
surface water during the 2013 investigation. The channel makes a 90 degree bend at Davis Lane,
continuing north on the west side of Davis. The channel slopes are steep and 6 to 8 feet high.
There is an approximately one-foot strip of wetland fringe at the base of the channel segment
located south of the gravel road.
Vegetation
The wetland plants at the base of the channel included meadow foxtail, American
brooklime, spreading bentgrass, beaked sedge, Nebraska sedge, arctic rush, Bebb’s willow, and
balsam cottonwood. One hundred percent of the dominant species were hydrophytic.
Soil
No test pit was excavated. There was no surface water during the investigation. The
channel was classified as a water of the US.
Hydrology
The Section Line Ditch was not flowing during the August 2013 investigation. There
was a distinct OHWM.
3.9 W-13 – STORMWATER POND – WATER OF THE US
Wetland W-13 is a stormwater pond (Photo 19) that connects to W-3 at the downgradient
end through a pipe and culvert. The stormwater pond was constructed for development of the
Baxter Meadows Subdivision. Although man-made, the pond was considered to be a water of the
US based on the downgradient surface water connection to W-3. The pond was excavated in
cobble material. The steep slopes support a limited cover of wetland plants. Plants identified at
the water’s edge included broad-leaf cattail, Nebraska sedge, fringed willow herb, and common
spike rush. Upland plants on the upper slopes included smooth brome, Western wheatgrass
(Pascopyron smithii), and orchard grass (Dactylis glomerata). No test pit was excavated. The
pond was located within the Enbar loam map unit. The lowest contour of the pond was filled
with surface water during the investigation.
Waters of the US Delineation Report – Tracy – COS 2202C 15
4.0 SUMMARY
Thirteen wetlands were identified within the study area. Wetlands W-7 and W-8 were
preliminarily classified as isolated, non-jurisdictional wetlands based on the lack of a connection
to a water of the US. The remaining wetlands were classified as jurisdictional.

Development activities resulting in the placement of fill in wetlands determined to be
jurisdictional will require a USACE Section 404 permit. Project-wide wetland impacts totaling
less than 0.5 acres are administered under the Nationwide Permit program while impacts
Waters of the US Delineation Report – Tracy – COS 2202C 16
exceeding 0.5 acres in extent come under the Individual Permit process. Compensatory
mitigation will be required for the loss of any jurisdictional wetland over one-tenth of an acre at a
ratio determined by the USACE.

inches.
Dalmation (CO) - does not have a lithologic discontinuity between 40 and 60 inches.
Jodero (CO) - does not have redox features above a depth of 40 inches; is well drained; is not calcareous
throughout.
McGaffey (NM) - is well drained; has hues of 7.5YR and redder in the lower part of the control section.
Nutrioso (AZ) - is well drained; has a discontinuity in the particle-size control section.
Pinridge (CO) - is well drained; has horizons of secondary carbonate accumulation; does not have a gleyed
horizon.
Straw (MT) - is well drained; does not have redox concentrations or a gleyed horizon.
GEOGRAPHIC SETTING:
Landform - flood plains; drainageways; stream terraces.
Elevation - 3,500 to 6,000 feet.
Slope - 0 to 15 percent.
Parent material - alluvium derived from mixed rock sources.
Climate - long, cold winters; moist springs; warm summers.
Mean annual precipitation - 14 to 22 inches.
Mean annual air temperature - 37 to 45 degrees F.
Frost-free period - 70 to 125 days.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; moderate permeability.
USE AND VEGETATION: Enbar soils are used mainly for pasture, hay, and rangeland and to a lesser degree
for cropland. Potential native vegetation is mainly slender wheatgrass, western wheatgrass, reed canarygrass,
prairie cordgrass, American mannagrass, tall sedges, forbs, and shrubs.
DISTRIBUTION AND EXTENT: Enbar soils are moderately extensive in central Montana and adjacent
areas.
