Wetland and Waterbody Assessment Report
1-1 December 2021
1 INTRODUCTION
On behalf of the Bozeman Trax Partners, Weston Solutions, Inc. (WESTON) completed a wetland
and waterbody assessment for the 275-acre North Park Development (Project) in Bozeman,
Montana. The Site is bound by North 7th Avenue to the east, Mandeville Drive to the south,
Interstate 90 to the west, and Red Wing Drive to the north. The Montana Rail Link Railroad runs
parallel to Red Wing Drive north of the Site WESTON conducted the wetland and waterbody
assessment: to determine if wetlands and/or waterbodies are present within the proposed project
area, to identify the approximate boundaries of any wetlands or waters identified, and to determine
whether they would be considered jurisdictional by the United States Army Corps of Engineers
(USACE).
Wetlands and waterways were identified through the evaluation of wetland criteria (hydrology,
soils, vegetation) and the potential jurisdictional status as Waters of the United States. The
jurisdictional assessment provided in this report is subject to a final Jurisdictional Determination
made by the USACE and the United States Environmental Protection Agency (EPA). As outlined
in CFR Vo. 51. No.219, the USACE and EPA reserve the right to determine jurisdiction on a case-
by-case basis. Weston identified approximately 8 acres of potentially jurisdictional riparian
wetlands on Site.
1.1 1.1 PROJECT DESCRIPTION
The Site is located in the City of Bozeman’s in Gallatin County (Figure 1-1). City of Bozeman
owns the northern portion of the Site encompassing approximately 85 acres, and the Montana
Department of Natural Resources and Conservation owns the southern portion of the Site
encompassing approximately 190 acres. The Site elevation ranges from 4718-feet to 4677-feet and
the area topography slopes to the northeast toward the East Gallatin River. The Site land use is for
agriculture, consistent with both crop production and livestock grazing.
Mandeville Creek and Spring Creek flow north from the southern portion of the Site connecting
approximately 0.23 miles (1,203 feet) north of the southern Site boundary line. Spring Creek
continues flow north through the center of the Site and exiting at the northern Site boundary. The
creeks are narrow and perennial with an herbaceous vegetation corridor. However, there are some

cottonwood and willow species near the southern boundary of the property. The Site survey area
includes the entire 275 acres including the land between Redwing Road and the railroad track, as
shown on Figure 1-2.
1.2 1.2 LIMITATIONS
WESTON performed the wetland and waterbody assessment for the North Park Development in
conformance with the scope and limitations of the USACE Corps of Engineers Wetland
Delineation Manual (USACE, 1987) and the Western Mountains, Valleys and Coast Regional
Supplement to the Corps of Engineers Wetland Delineation Manual (USACE, 2010). The results
presented in this report are based on review of available current and historical information, a
desktop evaluation, and a field assessment conducted 6 and 7 October 2021 by WESTON. The
findings and conclusions presented herein are professional opinions based solely on visual and
physical observations of the survey area and interpretation of information provided or reasonably
available to WESTON.
1.3 1.3 REGULATIONS AND DEFINITIONS
The USACE regulates, “Waters of the U.S.,” wetlands, and special aquatic sites under Section 404
of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act. Waters of the United
States is defined through statute, regulation, and judicial interpretation to include all waters that
were, are, or could be used in interstate commerce such as interstate lakes and rivers as well as
intrastate lakes, rivers, streams (including ephemeral streams), mudflats, wetlands, sloughs, prairie
potholes, playa lakes, and ponds. The USACE and the U.S. Environmental Protection Agency
(EPA) define wetlands 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. Wetlands typically
include swamps, marshes, bogs, and other similar areas” (40 Code of Federal Regulations [CFR]
230.3[t]). This definition takes into consideration three (3) distinct environmental parameters:
hydrology, soil, and vegetation. Positive wetland indicators of all three (3) parameters are normally
present in wetlands.
Weston Solutions, Inc.
Wetland and Waterbody Assessment Report
1-3 December 2021
Although a feature may meet the USACE/EPA criteria for a “wetland,” not all areas identified as
wetlands are subject to jurisdiction by the USACE under the CWA.
Although jurisdictional status is dependent on regional USACE regional district adaptations, the
current interpretation of “waters of the United States” is based on the pre-2015 to identify the scope
of Waters of the United States that fall under USACE jurisdiction (USEPA 2021): These include:
1) All waters which are currently used, or were used in the past, or may be susceptible to
use in interstate or foreign commerce, including all waters which are subject to the ebb
and flow of the tide
2) All interstate waters including interstate wetlands;
3) Tributaries;
4) Waters such as lakes, ponds and impoundments of jurisdictional waters, rivers, streams
(including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes,
wet meadows, playa lakes, or natural ponds, which are or could be used in any interstate
or foreign commerce;
5) All impoundments of waters otherwise defined as waters of the United States;
6) Adjacent wetlands;
7) This wetland and waterbody assessment and jurisdictional analyses was completed based
on the definition as described above.

2 SURVEY METHODOLOGY
The methodology applied in this wetland and waterbody assessment include both desktop analysis
and field survey. The desktop analyses include the review of publicly available data. Findings from
the desktop analysis were applied to the field survey to assist in the selection of locations within
the subject project survey area requiring detailed or more cursory evaluation.
The field survey included observations of the entire survey area. To verify the presence or absence
of wetlands, depressional areas and ditches were evaluated through the establishment of wetland
data points. Each data point was assessed for vegetation, soils, and hydrology indicative of
wetlands as described by the USACE manual and regional supplement. Additionally, non-wetland
waters regulatory boundaries, such as streams without adjacent wetlands, are limited by the
ordinary high-water mark. The ordinary high-water mark is measured by:
a clear natural erosion line impressed on the bank;
changes in the character of the soil;
destruction of terrestrial vegetation due to inundation;
the presence of litter and debris;
stain marks on rocks or bridge piers; or
other appropriate means that consider flow characteristics of the stream.
2.1 DESKTOP ANALYSIS

2017 Wetland Delineation Report performed by Allied Engineering Services, Inc.
The analysis of these documents assisted in the planning and execution of the field survey by
identifying potential drainage contours, wetland, pond, or similar general habitat characteristics.
2.1.1 Aerial Photographs
Aerial photography available through Google Earth for the years 1985, 1995, 2003, 2004, 2005,
2006, 2009, 2011, 2014, 2020 and 2021 was reviewed. The aerial photos were reviewed to
establish the history of water features on the site and to evaluate potential connection to regional
waters. Spring Creek and Mandeville Creek are visible in the photographs, they merge and flow
north through the Site to the East Gallatin River, located approximately 1000 feet north of the Site.
The Site appears to be used for agriculture throughout the years of available aerial imagery. The
Site is observed to be seasonally plowed except for the approximately 400-foot-wide buffer around
Spring and Mandeville Creeks. No other areas of persistent surface water are identifiable on the
aerial photographs.
2.1.2 Montana Digital Atlas
Digital maps from the Montana Digital Atlas and MTNHP Map Viewer containing watershed,
wetland, and stream and lake layers were reviewed prior to field investigation to identify potential
aquatic resources on Site and in the surrounding area. The digital maps show Spring and
Mandeville Creeks flowing north through the property. No additional wetlands or waterbodies are
evident.
2.1.3 FEMA Maps
FEMA floodplain maps were reviewed to identify if the Site might contain isolated wetlands
within the 100-year floodplain. The 100-year and 500-year floodplain is mapped approximately
0.11 miles (589 feet) north of the Site along the East Gallatin River (Figure 2-1).
2.1.4 Soil Survey
The USDA NRCS maintains an online soil mapping/viewing program of the soil series
throughout 95 percent of the U.S., including hydric soil series. The presence of a hydric soil in
Weston Solutions, Inc.
Wetland and Waterbody Assessment Report
2-3 December 2021
an area can be an indicator of the presence of wetlands. Hydric soil is defined as a soil that is
formed under conditions of saturation, flooding, or ponding long enough during the growing
season to develop anaerobic conditions in the upper part of the soil column. A list of hydric soils
by county is maintained by the USDA.
According to the USDA, NRCS Soil Surveys for Gallatin County (USDA, 2021), five (5) soil
series are mapped on Site. Soils mapped by USDA are shown on Figure 2-2. The Enbar loam
soil series underlays the area along the Creeks. A minor component of the series is considered
hydric. The remaining four soil series on Site are not classified hydric soils.
2.1.5 National Wetlands Inventory
The NWI was established by the USFWS to conduct a nationwide inventory of U.S. wetlands and
to provide information on the distribution and type of wetlands potentially present to aid in
conservation efforts. The data are available through an online mapping program. The data for the
mapping program have been collected through a variety of sources and do not represent a
comprehensive database of all wetlands present in the U.S. Additionally, not all wetlands shown
have been field-verified. Therefore, the NWI is a valuable resource for understanding the wetland
potential at a site, but is not a conclusive, stand-alone indicator of wetlands’ presence or absence.
WESTON reviewed the NWI for the site and surrounding area (Figure 2-3). As shown on the
figure, the Mandeville and Spring Creeks and their associated palustrine wetlands are present
within the Site. No other NWI wetlands are mapped on Site.
Based on this desktop analysis, WESTON determined the following:
Aerial photography showed the property has consistently been used for agriculture. The
photography also shows Spring and Mandeville Creeks flowing north through the
southcentral portion of the property before Mandeville Creek merges with Spring Creek.
Spring Creek continues to flow north through the center of the Site to its confluence with
the East Gallatin River.
FEMA floodplain mapping was reviewed prior to the site visit. None of the Site is within
the 100-year or 500-year floodplain (Figure 2-1).
Weston Solutions, Inc.
Wetland and Waterbody Assessment Report
2-4 December 2021
The United States Department of Agriculture (USDA) soil survey was reviewed for the
Site (Figure 2-2). A soil with hydric inclusions is present along the Mandeville and Spring
Creeks. No other hydric soils are identified within the Site.
The NWI wetlands mapper identified a palustrine emergent, persistent, temporary flooded
(PEM1A) wetland along the Creeks; a palustrine, emergent, persistent, seasonally flooded
(PEM1C) wetland isolated in the southcentral portion of the Site; and a riverine,
intermittent, streambed, temporarily flooded (R4SBA) identified as the Creeks. (Figure 2-
3). No other wetlands or waters were mapped within the Site.
2.1.6 2017 Wetlands Delineation
A wetlands delineation was performed for the area south of Redwing Drive and north of Interstate
90. The area between the railroad ROW and Redwing Drive was not included in the original
delineation. The information from the 2017 delineation was verified and updated as necessary
during the 2021 field investigation.

3 FIELD INVESTIGATION
The Site was surveyed for wetlands on 6 and 7 October 2021 in accordance with the Corps of
Engineers Wetlands Delineation Manual (USACE, 1987) and the Regional Supplement to the
Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Cost Region
(USACE, 2010).
Weather conditions were typical for the time of year, although the entire region was experiencing
lower than normal rainfall. The rainfall for Sept 2021 was 0.13 inches compared to the median
rainfall for September of 1.35 inches based on records from 1991-2020 at the Bozeman Montana
State University weather station. Year to date precipitation was 16.73 inches compared to the 1991
to 2020 median of 18.67 inches (Montana State Library, 2021).
The entire site was walked for indicators of wetlands. Data from the 2017 delineation was verified
through the advancement of data points near 2017 data points. Wetlands and other waters were
identified including and adjacent to Mandeville Creek. Palustrine emergent wetlands identified
totaled 8.1 acres. Although the wetlands are continuous along Mandeville and Spring Creek, there
were slight differences identified specifically in the southern portion of the Site. Therefore, the
wetlands are presented as distinct wetlands although they are continuous. Two (2) data points
were evaluated at the wetland edges to verify the wetland-upland boundary. Each data point was
assessed for vegetation, soils, and hydrology indicative of wetlands as described by the USACE
manual and regional supplement. The locations of data points were recorded with a handheld
global positioning system (GPS) unit and are shown on Figure 3-1. Representative photographs of
the project survey area are provided in Appendix A. Wetland delineation datasheets are provided
in Appendix BVegetation
The site consisted of managed agricultural land and according to the aerial photography has been
managed agriculturally for at least 35 years. The area immediately adjacent to the creek slopes
towards the creek and, although altered, has not been managed as extensively. Common species
identified in the wetland areas included creeping foxtail (Alopecurus arundinaceus), red top, reed
canary grass (Phalaris arundinacea), tufted hairgrass (Dechampsia caespitosa), cattail (Typha
species), and various sedges (Carex species). Species identified at the upland boundary included
fescue (Festuca species), smooth brome (Bromus inermis), and timothy grass (Phleum pratense).

3.1 HYDROLOGY
Perennial surface water is present within Mandeville and Spring Creek. There is a clear connected
between the onsite creek and the Missouri River via the East Gallatin River. Although irrigation
practices appear to have ceased years ago, the corridor is influenced by irrigation practices that
may have modified the stream flow. Wetland hydrologic indicators identified in most of the
wetland data points are saturation and high-water table. The wetland data points were collected in
low areas adjacent to the stream. Other primary indicators include drift deposits, algal mat or crust,
surface soil cracks, hydrogen sulfide odor, and presence of reduced iron. Based on the 2017
delineation report, three existing piezometers were available for measurement near the
southcentral portion of the Site. Depth to groundwater measured in September 2017 ranged from
10-inches below ground surface (bgs) to 37-inches bgs.
Weston Solutions, Inc.
Wetland and Waterbody Assessment Report
3-3 December 2021
3.2 SOIL
The dominant soil series along the stream corridor and wetland area is the Enbar loam. The soil
type is somewhat poorly drained soil found across floodplains with 0 to 4 percent slopes. The
texture ranges from loam to a very gravelly loamy sand formed from an alluvial habitat. The soil
pits advanced in the wetland area matched the soil description of Enbar loam. The remaining
onsite soil types support the upland area. Details of the soils are included on the data sheets
provided in Appendix B and photographs are provided in Appendix A. Wetland soil pits were
primarily in silt loam and fine sandy loam. The primary hydric soil indicators included a Depleted
Below Dark Surface (A11) or Histosol (A1).
3.3 WETLAND CLASSIFICATION
The wetlands delineated on the site are identified as palustrine emergent wetlands (PEM).
Transitional vegetation species including creeping foxtail, red top and rush species were dominant
in saturated areas. Areas with surface water or high water tables included species such as sedges,
cattails, and tufted hair grass.
The primary wetland or waterbody feature on the Site are Mandeville and Spring Creeks. The
creeks ranged from 3 to 10 feet in width from top of bank to top of bank. The banks are steep cuts
through the field and generally are 2 to 5 feet in height. Water was present at depths of
approximately 2 feet throughout the creek during the survey. Outside of the steep banks, the
landform in some areas raised quickly with little adjacent wetland areas, but some adjacent areas
included flat terraces or depressions allowing for wetland conditions to exist. The streams are part
of the East Gallatin River Watershed (HUC12-100200081301). Mandeville Creek is a state
waterbody (MT41H003_021). Mandeville Creek is categorized as impaired.

3.4 3.5 JURISDICTIONAL STATUS
The streams and adjacent wetlands delineated on Site appear to be jurisdictional based on their
proximity to perennial watercourses; Mandeville Creek and Spring Creek, tributaries to East
Gallatin Creek located in the East Gallatin-Bozeman Watershed within the Missouri River
Headwaters. A jurisdictional determination should be made by the USACE.

3-5 December 2021
If the planned construction would impact the wetlands identified through the discharge of dredged
or fill material, permitting under CWA Section 404 is likely required. If final project plans include
impacts outside of the Site survey area, an additional evaluation of potentially jurisdictional waters
should be performed.
Best management practices (BMPs) to control pollutant discharges resulting from stormwater
runoff will help protect aquatic resources on and near the Site. BMPs include the use of erosion
and sediment controls to prevent sedimentation; minimizing the duration of the project; assuring
that construction vehicles are operating properly; and maintaining existing vegetation to avoid
increased erosion.
