Page | 1 Introduction A routine wetland delineation was conducted by Sundog Ecological Inc on May 19th, 2019 for Allied Engineering, Inc., on behalf of Headwaters Academy to accompany permitting materials being submitted to City of Bozeman for construction purposes. The project site is located at 1005 Durston Road in Bozeman, Montana. The purpose of this wetland delineation was to investigate the project area, identify areas meeting the technical guidelines for wetlands, delineate the extent of wetlands within the project area and classify these wetland habitats. This report describes the methodologies used, summarizes results of the 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. Headwaters Academy is proposing improvements to property at 1105 Durston Avenue in Bozeman, Montana. This report reviews a wetland/watercourse delineation conducted on the property approximately 131,551 square feet (3.02 acres). One wetland totaling 34 square feet and one open water pond (0.09 acres) were delineated within the project limits. A fifty-foot perimeter outside the property boundary was also evaluated for wetlands and no wetlands were identified within the 50-foot boundary. Identified wetland boundaries boarder Mandeville Creek and were drawn using field data and vegetative and topographic breaks. Wetlands were identified as forested palustrine wetlands. Upland vegetation was primarily Kentucky bluegrass; while wetlands were dominated by willow overstory and bare ground/litter understory. Site Description The Mandeville Creek at Headwaters Academy site is located in the City of Bozeman in central Gallatin County, Montana in Section 1, Township 2 South; Range 5 East, as shown in Figure 1. This property was historically used as a private residence and will now be used as the headquarters for Headwaters Academy, an independent middle school. Mandeville Creek is a small, first order spring fed stream. Upland communities are comprised of Kentucky bluegrass, orchard grass, litter and overstory trees; while wetlands are dominated by willows, bare ground and litter. One wetland, one open water feature and one upland type were identified within the project boundaries. Mandeville Creek @ Headwaters Academy Wetland Delineation Report Sundog Ecological Inc. Page | 2 Figure 1: Location of the Mandeville Creek Wetland/Watercourse Delineation Site relative to Durston Road, Bozeman, Montana. Methods This wetland 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 indicators of three wetlands parameters 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 does not usually qualify as a wetland. 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, the Gallatin County Soil Survey, Web Soil Survey, the National Wetlands Plant List, plat and topographic maps. Site maps used for assessment of the Mandeville Creek at Headwaters Academy wetland/watercourse delineation site are included in Appendix A. Mandeville Creek @ Headwaters Academy Wetland Delineation Report Sundog Ecological Inc. Page | 3 As part of a delineation report, data forms and technical information are required by the ACOE to document the three parameters for any area determined to be wetland. A total of five 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 Mandeville Creek project location. In May 2019, 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, five data points (3 wetland and 2 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 and one open water were identified within the project boundaries in immediate proximity to the Mandeville Creek stream channel. The location of identified wetlands, open water and upland/wetland sample points 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. Vegetation Approximately ten plant species were identified at data point locations (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 minimally on site.

Page | 4 Table 1: List of plant species observed at the Mandeville Creek @ Headwaters Academy Wetland/Watercourse Delineation Site. Delineated Wetlands Wetland Type 1 represents forested palustrine wetlands dominated by golden willow and balsam poplar. A map of delineated wetlands located in Appendix B shows delineated wetlands along Mandeville Creek and those extending into the Headwaters property. Wetlands were delineated outside the Headwater’s Academy property boundary to enable project proponents to establish City of Bozeman watercourse regulation buffer zones. The total amount of wetlands located within the Headwater’s property boundary are 34 square feet. This wetland type is considered jurisdictional because of the connection between Mandeville Creek and the East Gallatin River. Table 2: Wetland characteristics identified at the Mandeville Creek @ Headwaters Academy Wetland/Watercourse Delineation Site. Soils One soil map unit was observed within the project limits of the Mandeville Creek wetland delineation site. Mapped soil units observed on site were the Turner loam. In general, wetland soils are a combination of silt loam or loam with matrix hues of 10YR, matrix values of 1 to 2 and matrix chroma of 2 or less. Redox concentrations were observed throughout wetland soils within the project area.

Page | 5 were redox dark surface (F6) had values of 4 or 5 and chroma of 3 to 6. 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 geomorphic position (D2) and a positive FAC-neutral (D5) test. Riverine wetlands are sourced by stream flows, seasonal flows of Mandeville Creek and storm water pulses. Wetland Boundaries Mandeville Creek is the main driver of hydrology on site. Secondary hydrology is influenced by surface water flow and high runoff events. Mandeville Creek varies in width from four to ten (4-10) feet wide and one and a half to two (1.5-2.0) feet deep. Open Water One open water (pond) feature was identified within the project boundaries. This pond is 3,942 square feet (0.09 acres) and estimated to be 4.50 to 6.0 feet deep. Unofficial soil pits around the pond show no hydric soils; however, wetland vegetation (reed canary grass) was observed on one bank where a small slope occurs. The pond is primarily fed by a breach in the berm on its west side which allows water from Mandeville Creek to enter. There was no outflow channel and no water was observed exiting or seeping from the pond. Because of the pond’s connection to Mandeville Creek and Mandeville Creek’s connection to the East Gallatin River, the pond is considered to be jurisdictional. Uplands A total of two upland sample points (paired with three wetland sample points) were documented within the project area and are shown on the accompanying project/site maps (Appendix B). These sample points were used to assist in establishing wetland boundaries and to determine/verify upland/wetland boundaries. Taken throughout the project limits, these sample points varied throughout the upland areas. Uplands generally occurred in slightly higher topography, bordering the narrow wetland fringe associated with Mandeville Creek. Vegetation within the uplands included a mix of hydrophytic and upland species. Common species noted in the uplands included: Kentucky bluegrass, orchard grass and common dandelion. Soils were primarily a very dark greyish brown (10YR 3/2) and lacking redox concentrations. Textures were silt loam, similar to descriptions found in Soil Survey information provided in Appendix A. Wetland and Stream Impacts/Mitigation This Wetland Delineation Report for the Mandeville Creek at Headwaters Academy site provides baseline information that will assist in developing practices to minimize wetland and stream impacts during the construction process. Mandeville Creek @ Headwaters Academy Wetland Delineation Report Sundog Ecological Inc. Page | 6 Because there will be no impacts to wetlands/watercourse, a Montana Joint Permit Application is not required and has not been filed. Summary One wetland, one open water and one upland type were identified within the project boundary totaling 34 square feet, 0.09 and 2.71 acres, respectively. Wetland areas were limited to a narrow corridor along Mandeville Creek that is dominated by golden willow, balsam poplar and Kentucky bluegrass. Wetlands identified on site were forested palustrine wetlands. Mandeville Creek @ Headwaters Academy Wetland Delineation Report Sundog Ecological Inc. Page | 7 References Cowardin, L.M., V.

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.
