1 EXECUTIVE SUMMARY
Morrison-Maierle, Inc. delineated wetlands and other aquatic features at an approximately 115-acre property located west-southwest of the intersection of Davis Lane and East Valley Center Road, northwest of Bozeman, MT for Virga Capital. A vicinity map of the investigation area is in Appendix A (Figure 1).
Prior to the field investigation, our environmental scientists review existing literature relevant to the project area, including historical aerial photography, topographic maps, and hydrologic data. Field delineation of wetlands and other aquatic features is based on identification of hydric soil conditions, wetland hydrology, and hydrophytic vegetation. We evaluated the investigation area based on criteria set forth in the 2010 Regional Supplement to the U.S. Army Corps of Engineers USACE Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (Environmental Laboratory 2010).
Based on the wetland delineation presented in this report and the data collected, it is Morrison-Maierle’s professional judgement that waters of the U.S. are present within the project area. The project area contains 2,480 linear feet (0.12 acres) of waterway and 0.39 acres of palustrine emergent wetlands. Cattail Creek (1,010 linear feet, 0.05 acres) traverses the northeast corner of the project area and contains fringe wetlands (0.09 acres) dominated by reed canary grass. The unnamed tributary to Buster Gulch (1,470 linear feet, 0.07 acres) in the southwest corner of the property is used for irrigation of the property and also contains fringe wetlands (0.30 acres) dominated by reed canary grass. Due to the features being located along or crossing the property parcel boundary, the features extend beyond the parcel and totals may not necessarily represent what lies only within the project area.
Figure 5 in Appendix A details the investigation area and delineated features. Table 3 in Section 5 summarizes the wetlands and aquatic features delineated within the project area.
The USACE and the U.S. Environmental Protection Agency (EPA) are the final authority over the jurisdictional status of both wetlands and waters of the U.S. according to Section 404 of the Clean Water Act. The findings discussed in this report are solely the opinion of Morrison-Maierle and have not been verified by the regulatory government agencies.

2 INTRODUCTION
2.1 Purpose and Scope
Morrison-Maierle completed a wetland delineation, at the request of Virga Capital, of approximately 115 acres of property in Gallatin County, Montana (Appendix A, Figure 1). The investigation area is agricultural land situated west-southwest of the intersection of Davis Lane and East Valley Center Road, northwest of Bozeman. The investigation is comprised of three parcels with the following legal descriptions:
• S27, T01 S, R05 E, ACRES 56.81, W2W2NE4, W2E2W2NE4 LESS HWRW
• S27, T01 S, R05 E, ACRES 22.847, PT OF NE4NE4, E2E2W2NE4 SOUTH OF ROW
• S27, T01 S, R05 E, ACRES 36.05
2.2 Background Information
The subject property has historically been utilized for agricultural purposes. The proposed Turnrow Subdivision encompasses a total of 114.69 acres and is generally located at the southwest corner of the intersection of Valley Center Road and Davis Lane. The property is within the boundaries of the City of Bozeman, Montana and was annexed in September of 2022. The property is zoned REMU (Residential Emphasis Mixed Use).
2.3 Objectives
The objective of this report is to document the presence and extent of aquatic features on the subject property. This report also addresses additional items required by the City of Bozeman Wetland Review Checklist (November 2022 Revised Edition).
2.4 Site Description
2.4.1 National Wetlands Inventory
The U.S. Fish and Wildlife Service (USFWS) maintains the National Wetlands Inventory (NWI) database, a publicly available resource providing detailed information on the abundance, characteristics, and distribution of U.S. Wetlands. The NWI database is based on a model that predicts the presence of wetlands from various parameters and does not necessarily reflect ground conditions.
According to the NWI database, one freshwater emergent wetland (PEM1Ax) crosses the southwest corner of the property, and one freshwater emergent wetland (PEM1A) crosses the northeast corner of the property (USFWS 2023). Appendix A, Figure 4 depicts the NWI features in the project vicinity.

2.4.2 Streams & Topography
One intermittent stream / irrigation ditch traverses the southwest corner of the investigation area and is considered an unnamed tributary to Buster Gulch. One intermittent stream, Cattail Creek, traverses the northeast corner of the investigation area.
The unnamed tributary to Buster Gulch appears to flow after the typical irrigation season is over, therefore this feature is likely a stream-ditch. A topographic map of the subject property is provided in Appendix A (Figure 2).
The investigation area is gently sloping with elevations between approximately 4,600 to 4,630 feet above sea level according to the Bozeman, MT (2020) U.S. Geological Survey (USGS) 7.5-minute topographic map. An unnamed intermittent stream is shown along the western property boundary as well as an unnamed intermittent stream and associated riparian habitat along the northeast and eastern property boundaries.
2.4.3 Soils
Four mapped soil types identified in the investigation area are summarized in Table 1. No hydric soils are located on the property. See section 3.2.2 for a discussion of hydric soils and wetland conditions.

2.4.4 Floodplains
The subject property is located outside of the 100-year floodplain. The project area is located within Federal Emergency Management Agency (FEMA) FIRM Panel 30031C0802D for Gallatin County Unincorporated Areas with an effective date of September 2, 2011. A custom FEMA map is provided in Appendix E.
3 METHODS
3.1 Sampling Protocol
This wetland delineation utilizes the methodology presented in the 1987 U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory 1987) and
Davis Lane 115-ac Property Wetland Delineation 6916.004
4 | Page
subsequent modifications outlined in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (Environmental Laboratory 2010). The methodology includes sampling procedures for vegetation, hydrology, and soil parameters.
3.2 Wetland Indicators
3.2.1 Vegetation
Vegetation at upland and wetland data points is classified based on wetland indicator status. The indicator status of vegetation was derived from the USACE 2020 National Wetlands Plant List (NWPL). Using the current plant list, vegetation cover qualified as hydrophytic where over 50% of the dominant plant species had an indicator status of obligate (OBL), facultative wet (FACW), and/or facultative (FAC). FAC plants, such as Canada thistle (Cirsium arvense), are equally likely to occur in wetlands and non-wetlands. Vegetation cover was considered as upland where over 50% of the dominant plant species were classified as upland (UPL), and/or facultative upland (FACU). Plants observed within each data plot were identified using Montana Manual of Vascular Plants (Lesica 2012). Vegetation nomenclature follows USACE NWPL (2020) and Lesica (2012).
3.2.2 Soil
Wetlands must meet the qualifications of at least one hydric soil indicator or meet the definition of a hydric soil (a soil that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part (NRCS 2019a). Soils at each data point were evaluated and described notating the depth, matrix color, mottle abundance and contrast (if present), texture, etc. (Environmental Laboratory, 1987 and 2010). Moist matrix color and moist mottle color of the soils were determined utilizing the Munsell Soil Color Chart (Kollmorgan Instruments Corporation, 2009).
3.2.3 Hydrology
Primary and secondary hydrologic indicators were assessed at each data point; one primary indicator or two secondary indicators are required to qualify the area as containing wetland hydrology. Examples of primary hydrology indicators are saturation within 12 inches of the ground surface, surface water, and water table within 12 inches of the ground surface. Examples of secondary hydrology indicators are FAC-neutral test and geomorphic position on the landscape.
3.3 Delineation Procedure
Upland data points (UDP) and wetland data points (WDP) are established as required during the field investigation. Vegetation, hydrology, and soils data is collected in the field according to protocols established by the USACE and recorded on USACE Wetland Determination Data Forms (Environmental Laboratory 1987). Photographs are taken at each data point. Sample points are collected with a handheld GPS device. Wetland boundaries, if present, are flagged by the environmental scientist and surveyed by a licensed surveyor. Data is postprocessed in ArcGIS to create maps and perform calculations.

4 RESULTS
4.1 Wetland Types and Boundaries
A Morrison-Maierle environmental scientist completed a wetland delineation of the project area on October 1, 2021. Two wetlands and two distinct stream features transect in the project area (Figure 5, Appendix A). Wetlands are immediately adjacent to the stream features.
Cattail Creek (1,010 linear feet, 0.05 acres) traverses the northeast corner of the project area and contains palustrine emergent wetlands (WET 1 = 0.09 acres) dominated by reed canary grass. The stream boundary was delineated by the presence and location of the ordinary high-water mark. The wetland boundary was delineated by changes in vegetation community, presence of hydric soils, and geomorphic position.
The unnamed tributary to Buster Gulch (1,470 linear feet, 0.07 acres) in the southwest corner of the property is used for irrigation of the property and contains fringe palustrine emergent wetlands (WET 2 = 0.30 acres) dominated by reed canary grass. The wetland boundary was delineated by changes in vegetation community, presence of hydric soils, and geomorphic position.
4.2 Upland Areas
The wetland/upland boundary within the subject property primarily follows a change in topography, vegetation regime, and distance frum surface water influences. The remainder of the property is under circle pivot irrigation and active agricultural use.
4.3 Data Summary
The vegetation, hydrology, and soil characteristics at each of 10 data points were documented in the field and recorded on USACE Wetland Determination Data Forms for the Western Mountains, Valleys, and Coast Region (USACE 2020). See Table 2 for a summary of collected data.

4.3.1 Vegetation
Vegetation communities were evaluated and documented to delineate wetland and upland boundaries, where existing. The location of all data points is identified on Figure 5 (Appendix A).
Grass species and weeds dominate vegetation in upland areas. Dominant species include:
Intermediate wheatgrass (Thinopyrum intermedium, UPL)
Smooth brome (Bromus inermis, UPL)
Canada thistle (Cirsium arvense, FAC)
Data points pass the Dominance test and Prevalence index at Wetland 1 and Wetland 2. Non-dominant species include Canada thistle and field mint (Mentha arvensis, FACW). Dominant species include:
Reed canarygrass (Phalaris arundinacea, FACW)
4.3.2 Soil
Soils were analyzed in the field for texture and color using the Munsell Soil Color Charts (Munsell 2009).
No hydric soil indicators were observed at upland data points. Soil colors are dark at 10YR 3/2, with granular structure and silty clay loamy textures from 0-16 inches. Many fine roots and few medium roots occupied the upper 4-6 inches of the profiles observed.
Wetland soils met the Redox Dark Surface (F6) hydric soil indicator. Soils exhibited a 10YR 2/1 silty clay loam from 0-16 inches with two percent 10YR 3/6 redoximorphic concentrations in the matrix. Roots were present in the upper 4-6 inches of the profiles.
4.3.3 On-Site Hydrology
Upland areas did not exhibit any hydrology indicators.
Davis Lane 115-ac Property Wetland Delineation 6916.004
7 | Page
Wetland areas met primary indicators of High Water Table (A2). The water table was present at 4 – 6 inches below the surface. Both wetlands follow, or border, surface water features and appear to be hydrologically connected to the stream/ditch. Secondary indicators including Geomorphic Position (D2) and FAC-Neutral Test (D5) are also present at the wetlands, with noticeably different vegetation cover and topography compared to adjacent upland areas.
4.4 Wetland Functional Assessment
A Wetland Functional Assessment was completed to satisfy requirements of the City of Bozeman Wetland Review Checklist (November 2022 Edition). The Montana Department of Transportation (MDT) Montana Wetland Assessment Form (revised March 2008) was used to conduct the analysis. The completed form can be found in Appendix D. The analysis within the form resulted in an overall analysis area rating of IV.
5 CONCLUSION
Based on the wetland delineation presented in this report and the data collected, it is Morrison-Maierle’s professional judgement that waters of the U.S. are present within the project area. The project area contains 2,480 linear feet (0.12 acres) of waterway and 0.39 acres of palustrine emergent wetlands. Figure 5 in Appendix A details the investigation area and delineated features. Table 3, summarizes the wetlands 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.

Map Unit Descriptions
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.
Custom Soil Resource Report

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
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.

Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

Description
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.
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).
