Page | 1 Introduction A routine aquatic delineation and investigation of waters of the U.S. was conducted by Sundog Ecological Inc on June 4th, 2021, for Hyalite Engineering, PLLC on behalf of the property owners. This delineation was conducted as part of due diligence for future land and infrastructure development in Gallatin County, MT. The project site encompasses 8.56 acres located at 6590 Davis Lane in Bozeman, Montana at Section 35, Township 1 South, Range 5 East. The purpose of this aquatic delineation was to investigate the project area, identify areas meeting the technical guidelines for aquatic resources (wetlands and watercourses), delineate the extent of these resources within the project area and classify these aquatic resource habitats. This report describes methodologies used, summarizes results of wetland investigations, and provides technical documentation for all delineated wetlands and watercourses within the project area. Figures referred to in text are included in Appendices at the end of the report. Site Description 6590 Davis Lane is located west of north 19th Avenue, north of Baxter Lane and borders the Section Line Ditch, see Figure 1. The Section Line Ditch flows north along the west property boundary for 470 feet, turns northeast for approximately 160 feet, then exits the property. The Section Line ditch abuts an abandoned railroad grade and driveway which creates ponding along 365 feet of the northern property boundary. The 6590 Davis Lane property is currently classified as a rural improved property. It has been a private residence with agricultural (currently a horse pasture) since 1975.

Page | 2 Methods This aquatic delineation was conducted using the routine on-site-approach in accordance with standard practices outlined in the 1987 Army Corps of Engineers (ACOE) Wetland Delineation Manual (Environmental Laboratory 1987) and by Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast - Version 2.0 (ACOE 2010). The study evaluated the presence or absence of three wetland indicators described in the ACOE Wetland Delineation Manual. Under the delineation procedures outlined in this manual, an area must exhibit characteristic wetland hydrology, hydric soils, and hydrophytic vegetation to be considered a wetland. If field investigation determines that any of the three parameters are not satisfied, the area may not qualify as a wetland, as under certain site conditions a site may qualify as a wetland in the absence of some indicators. Wetlands were classified according to the Cowardin classification system (Cowardin et al., 1979). Non-wetland water bodies such as streams were classified according to flow regime (perennial, seasonal, etc.) and substrate (rock bottom, unconsolidated bottom, etc.) according to the Cowardin system (Cowardin et al., 1979). Prior to conducting field studies, available background and supplementary reference materials were reviewed, including aerial photographs and maps from: Google Earth Pro, National Wetlands Inventory, Montana Natural Heritage Program, Gallatin County Soil Survey, Natural Resources Conservation Service (NRCS) Web Soil Survey, National Wetlands Plant List and plat and topographic maps. Site maps used for assessment of the Davis Lane Property Aquatic delineation site are included in Appendix A. As part of a delineation report, data forms and technical information are required by the ACOE to document the three indicators for any area determined to be wetland. A total of seven data points were observed. Wetland boundaries were drawn utilizing field data, aerial photographs and topographic boundaries. Data forms for sample locations are provided in Appendix B. Representative photographs of sample locations and delineated wetlands are provided in Appendix C. Results The following discussion provides an overview of each of the three wetland components inventoried at the 6590 Davis Lane project location. In June 2021, one wetland area was identified and delineated within the project boundaries. All potential areas of impact were assessed for dominant hydrophytic vegetation, hydric soils, and evidence of wetland hydrology. Wetland areas outside of the project limits were not assessed. Overall, seven data points (3 wetland and 4 upland) were investigated to determine the wetland/upland boundary within the project area. Data points were placed in and along the wetland/upland boundary. One wetland type was identified within the project boundaries in immediate proximity to the Section Line Ditch and in nearby depressional areas. The location of identified wetlands and upland/wetland sample points are shown on Exhibit 1, Appendix B. Data forms for sample locations can be found in Appendix C and photographs of sample locations in Appendix D. 6590 Davis Lane Aquatic Delineation Sundog Ecological Inc. Page | 3 Vegetation Approximately twenty-two (22) plant species were identified at data point locations at the Davis Lane delineation site (Table 1). Plants observed at these locations are listed on their respective wetland data forms located in Appendix C. Of the plant species observed, one is listed as a Montana State noxious weed; Canada thistle (Cirsium arvense). Canada thistle is classified as priority 2B weed and was observed across the site. A weed management plan should be implemented pre- and post-construction. Table 1: List of plant species observed at the 6590 Davis Lane Aquatic Delineation Site. Delineated Wetlands Wetland Type 1 represents palustrine emergent wetlands dominated by Nebraska sedge, clustered field sedge, white clover and Baltic rush. Wetlands were associated with fringes of the Section Line Ditch and areas backwatered from the it. Depressional wetlands were also observed and were likely influenced by backwatering of the irrigation ditch. The total amount of palustrine emergent wetland identified on site was 1.55 acres.

Page | 4 Table 2: Wetland characteristics identified at the 6590 Davis Lane Aquatic Delineation Site. Soils Two soil map units were observed within the project limits of the 6590 Davis Lane aquatic delineation site. Based on soil descriptions, both the Enbar loam and Blossberg loam are typically found along stream terraces and floodplains and are common throughout the Gallatin Valley. In general, observed wetland soils were loam to silt loam in texture with matrix hues of 10YR, matrix values of 2 to 4 and matrix chroma of 2 or less. Redox concentrations were observed throughout wetland soils within the project boundaries. Hydric soil indicators were depleted matrix (F3) and redox dark surface (F6). Detailed soil descriptions for wetland and upland sample locations are provided on wetland delineation data forms and can be found in Appendix C. Hydrology Primary indicators of hydrology observed were soil saturation (A3), (see completed data forms in Appendix B). Secondary indicators observed were saturation visible on aerial imagery (C9), geomorphic position (D2), a positive FAC-neutral (D5) test. Wetlands are sourced by seasonal irrigation flows and high runoff events. Water Bodies Section Line Ditch is the primary driver of hydrology on site. Secondary hydrology is influenced by surface water flow and high runoff events. The Section Line Ditch varies in width from one to ten (1-10) feet wide and one and a half to two (1.5-3.0) feet deep. Uplands A total of four upland sample points (paired with three wetland sample points) were documented within the project area and are shown on accompanying project/site maps (Appendix B). Sample points were used to assist in establishing wetland boundaries and to determine/verify upland-wetland boundaries. Taken throughout the project site, sample points varied across the upland areas. Uplands generally occurred in areas of slightly higher topography, bordering depressional areas and are associated with the Section Line Ditch. Vegetation within the uplands included a mix of facultative and upland species. Common species noted in the uplands included: common dandelion, white clover, orchard grass and musk thistle. Soils were primarily a very dark greyish brown (10YR 3/2) and lacking redox Site General Location Cowardin Class Primary Hydrology Dominant Vegetation Upland throughout project area none none dandelion, musk thistle, white clover, black medic, orchard grass Wetland Type 1 adjacent to Main Line Canal, depressional ares connected to canal palustrine emergent surface and ground water sedges, Baltic rush, bluegrass 6590 Davis Lane Aquatic Delineation Sundog Ecological Inc. Page | 5 concentrations. Textures were silt loam and loam, similar to descriptions found in NRCS Soil Survey information provided in Appendix A. Threatened and Endangered Species A review of USFWS Information, Planning and Conservation System database for the site listed the Canada Lynx and grizzly bear as threatened species in the area. Development of the Davis Lane site is not expected to impact either of these species as there are no critical habitats for them within the project area. Cultural Resources and Historic Structures There are no cultural resources, historic or other structures that would be impacted by development activities at the 6590 Davis Lane Aquatic delineation site. Summary This Aquatic delineation Report for the 6590 Davis Lane provides baseline information that will assist in developing practices to minimize wetland impacts during the site infrastructure and development process. One wetland and one upland type were identified within the project boundary. Wetland components total 70,567 square feet, or 1.55 acres. Wetland areas were limited to a narrow fringe bordering the Section Line Ditch along Davis Lane and a larger area of depressional wetland. Identified wetlands were classified as palustrine emergent wetlands. 6590 Davis Lane Aquatic Delineation Sundog Ecological Inc. Page | 6 References Cowardin, L.M., V. Carter, F.C. Golet, and E.T.

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, MontanaNatural Resources Conservation Service June 3, 2021 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.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate 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, Custom Soil Resource Report 11 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.
