(Morrison-Maierle) completed a wetland/waterway investigation for a 160 Acre parcel of property owned by the Anderson Family. This property is now referred to as Northwest Crossing This technical memo summarizes the findings of the 2018 wetland investigation in Gallatin County, Montana. The wetland/waterway investigations were completed on August 8 and 9th, 2018. The property is located at the near the intersection of Baxter Lane and Flanders Mill Road. The subject properties have historically been used for agriculture (crop and cattle) and rural residential. The land is legally described as Section 4, Township 2 South, Range 5 East, Certificate of Survey 2552, Tract 5 NE4, Principal Meridian, Gallatin County, Montana. Figures 1 to 5 are provided immediately following the memo and depict topographic project vicinity, aerial photographs, soils, National Wetland Inventories, and delineated wetlands/waterways. Additionally, Figure C-120 is included to show all surface water and wetland locations in survey-level detail. Photographs are provided in Appendix A and a Natural Resources Conservation Service soils report is provided in Appendix B. Wetland and Upland Data sheets are available in Appendix C. 2 Methods Wetland delineation data was collected on August 8 and 9, 2018. The wetland investigation utilized the methodology presented in the 1987 U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory 1987) and 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). 2.1 Wetlands Upland and wetland data points were established during the field visits. For wetlands and non- wetlands identified in 2018, wetland and upland plot data for vegetation, hydrology, and soils were recorded in the field onto Wetland Determination Forms, and are provided in Appendix A. The wetland identification numbers, (e.g. noted here in bold (W-1-18) correspond to the sample points for that location. Photographs of all sample points and wetlands are provided in Appendix A. The sample points and wetland boundaries were recorded by a professional land surveyor. 2.1.1 Vegetation Vegetation at upland and wetland data points was classified based on wetland indicator status. The indicator status of vegetation was derived from the Montana 2016 State Wetland Plant List (Lichvar et al. 2016). 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 Northwest Crossing Wetland/Waterway Investigation 2018 Page 2 Vascular Plants (Lesica 2012). Vegetation nomenclature follows Lichvar et al. (2016) and Lesica (2012). 2.1.2 Hydrology Primary and secondary hydrologic indicators were assessed at each wetland and upland 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. 2.1.3 Soils Soil types within the project area were obtained from the Web Soil Survey (NRCS 2002) and analyzed in the field for texture and color using the Munsell Soil Color Charts (Munsell 2000). 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 2016)). 2.1.4 Floodplains FEMA FIRM 30031C0802D Effective September 2, 2011. The Anderson Property is located on panel 300027 in Zone X: Area of Minimal Flood Hazard. This property is not located within a 100- year floodplain and therefore, would not require floodplain permitting should development occur. 2.1.5 National Wetland Inventory The US Fish and Wildlife Service maintains the National Wetlands Inventory (NWI), which serves as a publicly available resource that provides detailed information on the abundance, characteristics, and distribution of US Wetlands. According to the NWI database, a freshwater Emergent Wetland could potentially exist within the subject property. See Figure 4 and Appendix B for details. 3 Results The wetlands on the subject property are emergent riverine wetlands associated with a Baxter Ditch and Baxter Creek. The area along the unnamed drainage presented indications of previous disturbance and was likely plowed at one time. The wetland soils were not well developed. The area along Baxter Creek was trampled and heavily grazed by cattle. The wetland investigation resulted in the delineation of two riverine wetlands and three ordinary high watermarks of Baxter Ditch, Baxter Creek, and a tributary of Baxter Creek. Photographs of the investigation areas and wetlands are provided in Appendix A and Wetland Data Sheets are included in Appendix C. Two riverine wetlands associated with three waterways were delineated on the subject property. Additionally, the ordinary high watermark of Baxter Ditch, Baxter Creek, and a tributary of Baxter Creek were delineated. The majority of the channel of Baxter Ditch was vegetated but, the channel of Baxter Creek contained much less vegetation, likely due to the fact that it was located in an open active cattle pasture. Northwest Crossing Wetland/Waterway Investigation 2018 Page 3 3.1 Wetlands Wetland W-1-18 was delineated as a riverine wetland along the edges of Baxter Ditch. The wetland hydrology indicators for W-1-18 included high water table and saturation. Hydrology is provided by Baxter Ditch. Wetland W-2-18 was delineated as a riverine wetland along the edges of Baxter Creek. The wetland hydrology indicators for W-2-18 included high water table, redox, and topographical changes. W-1-18 (Riverine wetland to Baxter Ditch) Approximately 3.7 acres of wetlands were delineated as a wetland fringe to the un-named drainage on the subject property. The dominant vegetation observed within this area of the wetland included: field mint (Mentha arvensis, FACW), common cattail (Typha latifolia, OBL), reed canary grass (Phalaris arundinacea, FACW), and climbing nightshade (Solanum dulcamara, FAC). An infestation of noxious weeds were also observed within both the wetland and upland areas, including Canada thistle (Cirsium arvense, FAC) and common tansy (Tanacetum vulgare, FACU). The hydrophytic vegetation indicators include a positive dominance test and prevalence index within the range indicating the presence of hydrophytic vegetation. The wetland hydrology indicator is based on the water table at 8 inches below ground surface and geomorphic position. Soil observations of a 10YR2/1 clay loam layer from 0 to 10 inches below ground surface; unable to dig past 10 inches in most locations due to rocks or hardpack. The wetland soils were not well developed, assumingly due to previous disturbance from agricultural activities. Hydric soil indicator is assumed to be either Thick Dark Surface or Depletion Below Dark Surface (but could not dig deep enough to verify). The wetland/upland boundary primarily follows a change in topography, vegetation regime, and distance from surface water influences. Vegetation at the upland pit was dominated by Canada thistle (Cirsium arvense, FAC), Kentucky bluegrass (Poa pratensis, FAC), smooth brome (Bromus inermis, UPL), and woods rose (Rosa woodsii, FACU). In summary, the wetland boundary roughly followed historic meanders associated with Baxter Ditch. Several pits were dug along this corridor to verify the wetland boundary. Data sheets were not prepared for every pit due to the similar nature of each pit. W-2-18 (Riverine wetland to Baxter Creek and Tributary of Baxter Creek) Approximately 4.38 acres of wetland were delineated as wetland fringe to Baxter Creek and the tributary of Baxter Creek on the subject property. The north end Baxter Creek had a more developed natural floodplain than Baxter Ditch. This area was free from the influence of cattle (trampling and overgrazing) and the topography provided for wetland conditions. The dominant vegetation observed within this area of the wetland included: Baltic rush (Juncus balticus, FACW), Kentucky bluegrass, marsh cinquefoil (Potentilla paustris, OBL). The hydrophytic vegetation indicators include a positive dominance test and prevalence index within the range indicating the presence of hydrophytic vegetation. The wetland hydrology indicator is based on saturation at 9 inches and water table within 11 inches of the surface. Northwest Crossing Wetland/Waterway Investigation 2018 Page 4 Soil color from 0 to 18 inches was 10YR2/1 with 10% redox 10YR4/4 matrix at 8 inches. The wetland/upland boundary primarily follows a change in topography, vegetation regime, and distance from surface water influences. Vegetation at the upland pit was dominated by Canada goldenrod (Solidago Canadensis, FACU), snowberry (Symphoricarpos albus, FACU), Baltic rush and Kentucky bluegrass. Several pits were dug along this corridor to verify the wetland boundary. Data sheets were not prepared for all pits due to the similar nature of the data. The farther south on the subject property, the greater the riparian damage from cattle trampling and grazing. Wetland Summary Table Wetland Name Associated Waterway Area Type W-1-2018 Baxter Ditch 3.7 Riverine W-2-2018 Baxter Creek and Unnamed Tributary of Baxter Creek 4.38 Riverine 3.2 Waterways Waterway WW-1-18 (Baxter Ditch) Waterway WW-1-18 is identified as an unnamed tributary. Approximately 3,501 linear feet of this waterway was delineated within the investigation area. Much of the channel of Baxter Ditch is vegetated. This waterway was preliminarily determined to be jurisdictional based on its assumed confluence with a known Water of the U.S. Waterway WW-2-18 (Baxter Creek) Waterway WW-2-18 is identified as Baxter Creek. Approximately 3,737 feet of this waterway was delineated within the investigation area. Baxter Creek on the north end of the property had less negative influence from cattle trampling and grazing than on the south end of the property. Where Baxter Creek flows through the trees near the abandoned residential home, it is directed into what looks like a spring box and then it flows out the other side. A headgate is located on this creek which splits the water off into an unnamed tributary (WW-3-18) on the northwest side of the property. This waterway was preliminarily determined to be jurisdictional based on its assumed confluence with a known Water of the U.S. Waterway WW-3-18 (Tributary of Baxter Creek) Waterway WW-3-18 is identified as a Tributary of Baxter Creek. Water is split off into this Tributary by a headgate on Baxter Creek. Approximately 1475 linear feet of this waterway was delineated within the investigation area. This waterway was preliminarily determined to be jurisdictional based on its assumed confluence with a known Water of the U.S. Northwest Crossing Wetland/Waterway Investigation 2018 Page 5 Waterway Summary Table Waterway Label Waterway name Linear Feet Area (acres) Approx Width Source Vegetated?

Appendix B: NRCS Custom Soils Report United States Department of Agriculture A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Gallatin County Area, Montana Anderson 160 Natural Resources Conservation Service September 11, 2018 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.

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 Custom Soil Resource Report 6 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. Custom Soil Resource Report 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) 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.

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 Custom Soil Resource Report 11 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 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.
