Weston Solutions, Inc. Wetland and Waterbody Assessment Report 1-1 June 2023 1 INTRODUCTION On behalf of Bozeman Trax Partners, Weston Solutions, Inc. (WESTON), is submitting this wetland and waterbody assessment report for the 275-acre North Park Development (Project) in Bozeman, Montana. The Project is bound by Montana Rail Link Railroad to the north, North 7th Avenue to the east, Mandeville Drive to the south, and Interstate 90 to the west (Site). WESTON conducted a wetland and waterbody assessment on Site to determine the presence or absence of wetlands and waterbodies, delineate the approximate boundaries of any identified wetlands or waterbodies, and to determine whether the identified features would be considered jurisdictional by the United States Army Corp of Engineers (USACE). This wetland and waterbody assessment report has been prepared as a revision to the May 2022 Wetland and Waterbody Assessment Report. This report further assesses Spring Creek, Mandeville Creek, and associated wetlands on Site, and includes a portion of Spring Creek and associated wetlands north of Montana Rail Link Railroad (Survey Area). 1.1 PROJECT DESCRIPTION The Project is a 275-acre development project located in the city of Bozeman, Gallatin County, Montana (Figure 1-1). Currently, the Site consists of agricultural land use, including livestock pasture, barns, and crop fields. The Site elevation ranges from 4718-feet to 4677-feet and is generally sloped down towards the northeast and the East Gallatin River. Spring Creek and Mandeville Creek enter the Survey Area from the southern Site boundary, joining approximately 1,200 feet to the north. Spring Creek continues flowing north through the center of the Site crossing Montana Rail Link Railroad and Frontage Road before reaching East Gallatin River north of the Survey Area. The Survey Area is shown on Figure 1-2. 1.2 LIMITATIONS WESTON performed the wetland and waterbody assessment for the Project in conformance with the scope and limitations of the USACE Corps of Engineers Wetland Delineation Manual (USACE, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains. Valleys, and Coastal Region (USACE, V2.0 May 2010). The results Weston Solutions, Inc. Wetland and Waterbody Assessment Report 1-2 June 2023 presented in this report are based on review of available current and historical information, a desktop evaluation, and a field assessment of the Survey Area, conducted on 24-25 May and 1 June 2023 by WESTON. The findings and conclusions presented herein are professional opinions based solely on visual and physical observations of the Survey Area and interpretation of information provided or reasonably available to WESTON. The Survey Area is limited to the riparian corridor of Spring and Mandeville Creeks. Additional information regarding the Site outside of the Survey Area is included in the May 2022 Wetland and Waterbody Assessment Report. Wetlands and waterbodies are identified through the evaluation of wetland criteria (hydrology, soils, vegetation) and the potential jurisdictional status as Waters of the United States. The jurisdictional analyses of features provided in this report are subject to a final Jurisdictional Determination made by the USACE and the United States Environmental Protection Agency (EPA). 1.3 REGULATIONS AND DEFINITIONS The USACE regulates, “Waters of the United States,” wetlands, and special aquatic sites under Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act. The USACE and EPA define wetlands as, “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands typically include swamps, marshes, bogs, and other similar areas” (40 Code of Federal Regulations [CFR] 230.3[t]). This definition takes into consideration three distinct environmental parameters: hydrology, soil, and vegetation. Positive wetland indicators of all three parameters are normally present in wetlands. Although a feature may meet the USACE/EPA criteria for a “wetland,” not all areas identified as wetlands are subject to jurisdiction by the USACE under the CWA. Although jurisdictional status is dependent on regional USACE regional district adaptations, the current interpretation of “Waters of the United States” is based on the pre-2015 to identify the Weston Solutions, Inc. Wetland and Waterbody Assessment Report 1-3 June 2023 scope of Waters of the United States that fall under USACE jurisdiction (USEPA 2021). These include: 1) All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; 2) All interstate waters including interstate wetlands; 3) Tributaries; 4) Waters such as lakes, ponds and impoundments of jurisdictional waters, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, which are or could be used in any interstate or foreign commerce. 5) All impoundments of waters otherwise defined as waters of the United States; and 6) Adjacent wetlands. This wetland and waterbody assessment and jurisdictional analyses was completed based on the definition as described above. Weston Solutions, Inc. Wetland and Waterbody Assessment Report 2-1 June 2023 2 SURVEY METHODOLOGY The methodology applied in this wetland and waterbody assessment includes both desktop analysis and a field survey. The desktop analysis includes the review of publicly available data. Findings from the desktop analysis are applied to the field survey to assist in the selection of locations within the Survey Area requiring detailed or more cursory evaluation. The field survey includes observations of the entire Survey Area. To document the presence or absence of wetlands in the Survey Area, field observations are recorded on USACE Western Mountains, Valleys, and Coast Region Wetland Determination Data Forms at data plot locations. Wetland data plots document the presence or absence of wetland indicators such as wetland vegetation, soils, and hydrology as described by the USACE manual and regional supplement. Boundaries of identified wetlands will be delineated and recorded. Additionally, the presence or absence of waterbodies are established by identifying defined stream beds and banks. Boundaries of waterbodies are located and recorded by delineating the ordinary high-water mark (OHWM). The OHWM is measured by: • a clear natural erosion line impressed on the bank; • changes in the character of the soil; • destruction of terrestrial vegetation due to inundation; • the presence of litter and debris; • stain marks on rocks or bridge piers; or • other appropriate means that consider flow characteristics of the stream. 2.1 DESKTOP ANALYSIS The following sections describe background information utilized by WESTON prior to the field survey. A desktop analysis of the Survey Area was performed by reviewing the following sources: • Historical Aerial photography of the Survey Area (sourced from Google Earth) Weston Solutions, Inc. Wetland and Waterbody Assessment Report 2-2 June 2023 • Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FEMA, 2023) (Figure 2-1) • U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) web soils surveys for Gallatin County, MT (USDA, 2023) (Figure 2-2) • U.S. Fish and Wildlife Service (USFWS), National Wetlands Inventory (NWI) mapping (USFWS, 2023) (Figure 2-3) • Maps from Montana Digital Atlas and the Montana Natural Heritage Program (MTNHP) Map Viewer (accessed June 2023) (Figure 2-4) The analysis of these documents assisted in the planning and execution of the field survey by identifying potential drainage contours, wetland, pond, or similar general habitat characteristics. 2.1.1 Aerial Photographs Aerial photography available through Google Earth for eleven years between 1985 and 2021 were reviewed. The aerial photos were reviewed to establish the history of water features in the Survey Area and to evaluate potential connection to regional waters. The Survey Area and remaining portions of the Site appear to be consistently used for agricultural activities, except for residential use in the portion of the Survey Area north of Frontage Road. Portions of the Site outside of the Survey Area appear to be used for as crop production (hay/straw). As visible in aerial photography, the majority of the Survey Area appears to be fenced out, likely used as livestock pasture. The Survey Area contains Spring Creek and Mandeville Creek, which merge and flow north to the East Gallatin River, located approximately 1,000 feet north of the Site. No other areas of persistent surface water in the Survey Area are identifiable in aerial photography. 2.1.2 FEMA Maps FEMA floodplain maps were reviewed to identify if the Survey Area is within floodplains. Areas within floodplains areas may include unidentified wetlands and waterbodies. The entire Survey Area is outside of the 100-year and 500-year floodplain and is considered in an area of minimal hazard (Figure 2-1). Weston Solutions, Inc. Wetland and Waterbody Assessment Report 2-3 June 2023 2.1.3 Soil Survey The USDA NRCS maintains an online soil mapping/viewing program of the soil series throughout 95 percent of the U.S., including hydric soil series. The presence of hydric soil in an area can be an indicator of the presence of wetlands. Hydric soil is defined as a soil that is formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part of the soil column. A list of hydric soils by county is maintained by the USDA. Soils mapped by USDA within the Survey Area are shown on Figure 2-2. According to the USDA, NRCS Soil Surveys for Gallatin County (USDA, 2023), there are two dominant soil series mapped within the Survey Area, Enbar loam, and Turner loam. The Enbar loam complex does not have a major component listed as hydric, the minor component Nythar soils are hydric, occurring in floodplains. The Turner loam complex does not have major or minor components listed as hydric. 2.1.4 National Wetlands Inventory The NWI was established by the USFWS to conduct a nationwide inventory of U.S. wetlands and to provide information on the distribution and type of wetlands potentially present to aid in conservation efforts. The data are available through an online mapping program. The data for the mapping program have been collected through a variety of sources and do not represent a comprehensive database of all wetlands present in the U.S. Additionally, not all wetlands shown have been field-verified. Therefore, the NWI is a valuable resource for understanding the wetland potential at a site, but is not a conclusive, stand-alone indicator of wetlands’ presence or absence. WESTON reviewed the NWI online mapping program for the presence of wetlands and waterbodies within the site and surrounding area. Identified features within Survey Area are presented as Figure 2-3. As shown on the figure, there are several overlapping features within the Survey Area, similar to a wetland waterbody complex. A waterbody feature classified as Riverine, Intermittent, Streambed, Temporary Flooded (R4SBA) is assumed to be Spring Creek. A second waterbody feature classified as Riverine, Intermittent, Streambed, Seasonally Flooded (R4SBC) is assumed to be Mandeville Creek. A large wetland feature classified as Palustrine Emergent, Weston Solutions, Inc. Wetland and Waterbody Assessment Report 2-4 June 2023 Persistent, Temporary Flooded, (PEM1A) is located adjacent to the stream features. Additionally, the Survey Area contains small portions of wetlands classified as Seasonally Flooded (PEM1C), and Seasonally Flooded Excavated (PEM1Cx). Lastly in the northern portion of the Survey Area, north of Frontage Road, a wetland feature is identified as Palustrine, Scrub-Shrub, Seasonally Flooded (PSSC), appearing to overlap Spring Creek. 2.1.5 Montana Digital Atlas Digital maps from the Montana Digital Atlas and MTNHP Map Viewer containing watershed, wetland, stream, and lake layers were reviewed prior to field investigation to identify potential aquatic resources in the survey and surrounding area. Features within the Survey Area are presented as Figure 2-4. The Survey Area is within the East Gallatin River watershed (Hydrologic Unit Code 10020008). The East Gallatin River is located approximately 1,000 feet north of the Survey Area. According to the Montana Digital Atlas and MTNHP Map Viewer, Spring and Mandeville Creeks converge at the southern end of the Survey Area. No other features, including wetlands were identified within the Survey Area. Based on this desktop analysis, WESTON determined the following: • Aerial photography showed two streams identified as Spring Creek and Mandeville Creek, within the project Survey Area. The aerial photographs were inspected to identify possible connections between Survey Area and downstream waterbodies. Connections to the downstream East Gallatin River approximately 1,000 feet north of the Survey Area were apparent on aerial photography. • The FEMA floodplain mapping was reviewed prior to the site visit. None of the project Survey Area is within the 100-year or 500-year floodplain (Figure 2-1). • The USDA soil survey was reviewed for the project Survey Area (Figure 2-2). The majority of the Survey Area contained the Enbar loam complex. The complex’s minor component, Nythar is listed as hydric, occurring in floodplains. It is expected that soils adjacent to the creeks will exhibit hydric indicators. • The NWI figure (Figure 2-3) identifies several wetland features. PEM1A, PEM1C, and PSSC classifications indicate that, while wetland vegetation is persistent, temporary or Weston Solutions, Inc. Wetland and Waterbody Assessment Report 2-5 June 2023 seasonal flooding may not provide appropriate wetland hydrology. PEM1Cx classification indicates that these features are likely to be man-made ditches and not qualify as a wetland. • The NWI figure (Figure 2-3) identifies R4SBA and R4SBC streams. These classifications indicate that the feature is intermittent and is temporarily or seasonally flooded. These streams will likely be jurisdictional features with defined bed and banks; however they may not have enough flow to provide appropriate hydrology for fringing wetlands. • The Natural Heritage figure (Figure 2-4) identifies Spring and Mandeville Creeks. This figure does not identify a wetland feature unlike the NWI map. Further field evaluation of the Survey Area is necessary. Weston Solutions, Inc Wetland and Waterbody Assessment Report 3-1 June 2023 3 FIELD INVESTIGATION This field investigation was conducted to field verify the presence or absence of wetlands and waterbodies in the Survey Area. The Survey Area was investigated for wetlands and waterbodies on 24-25 May 2023 and 1 June 2023 in accordance with the methodology described in Section 2 and with the Corps of Engineers Wetlands Delineation Manual (USACE, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Cost Region (USACE, 2010). The locations of wetland boundaries, wetland data plots, and waterbody OHWM were recorded with a handheld global positioning system (GPS) unit and are shown on Figure 3-1. Representative photographs of the Survey Area are provided in Appendix A. Wetland delineation datasheets are provided in Appendix B. 3.1 RESULTS 3.1.1 Waterbodies Waterbodies in the Survey Area were identified and surveyed. Applicable data was gathered for each waterbody feature, including OHWM, approximate bank height, bank slope, stream-flow, stream substrate, aquatic habitats, channel conditions, and disturbances. Weather conditions were typical for the time of year, although the entire region was experiencing slightly higher than normal rainfall. According to the Montana State Library precipitation maps, the precipitation for April 2023 was 111% of normal (Montana State Library, 2023). As shown in Figure 3-1, The field investigation identified two waterbody features, Mandeville and Spring Creeks. 3.1.1.1 Mandeville Creek Mandeville Creek entered the Survey Area under Mandeville Drive via a culvert. Mandeville Creek flows north through several farm lane culverts and active pastures before reaching Spring Creek. The vegetation near Mandeville Creek generally consisted of emergent herbaceous forbs and grasses, being kept short with active livestock use. Portions of Mandeville Creek had fringing Weston Solutions, Inc. Wetland and Waterbody Assessment Report 3-2 June 2023 wetlands. Near the southern portion of the Survey Area, Mandeville Creek is shaded by several large willows. A few cottonwood trees line Mandeville Drive at Mandeville Creek. Mandeville Creek ranged in width from approximately 2 to 5 feet from top of bank, and a bank height of 1 to 2.5 feet. The banks generally had a slope near 2:1. Mandeville Creek was at bankfull during the field investigation with water depth ranging from 1 to 2.5 feet. Mandeville Creek substrate was sand with gravel and few cobble. The NWI classified Mandeville Creek as Riverine, Intermittent, Streambed, Temporally Flooded (R4SBA), however field observations and review of aerial photographs indicate that Mandeville Creek is a perennial stream having a defined bed, extensive fringing wetlands, and persistent flow visible in aerial photographs. Based on this field investigation, Mandeville Creek is now classified as Riverine, Upper Perennial, Unconsolidated Bottom, Sand, Temporally Flooded (R3UB2A). Mandeville Creek’s perennial flow and connection to Gallatin River via Spring Creek and East Gallatin River, meet the criteria for Waters of the United States under the jurisdiction of the USACE. 3.1.1.2 Spring Creek Spring Creek entered the Survey Area via a culvert from I-90 in the southwest corner. Spring Creek flows north through the Survey Area, crossing a cell phone tower access road via a culvert before merging with Mandeville Creek. Spring Creek continues through active pastures before nearing the northern portion of the Survey Area. In the northern portion of the Survey Area, Spring Creek passes under a Site access road (formerly Red Wing Drive), Montana Rail Link Railroad, and Frontage Road. Spring Creek exits the Survey Area and connects with East Gallatin River to the north. The vegetation near Spring Creek generally consisted of emergent herbaceous forbs and grasses, being kept short with active livestock use. Portions of Spring Creek were lined by peach- leaf willow (Salix amygdaloides) shrubs. Most of Spring Creek had fringing emergent wetlands. Spring Creek was notably meandering with several distant banks from old oxbows. Spring Creek ranged in width from approximately 5 to 10 feet from top of bank, and a bank height of 0 to 1 foot. The banks generally had a slope near 1:1, except where fringing wetlands were present. Spring Creek was at bankfull during the field investigation with water depth ranging from 2.5 to 4 feet. Spring Creek substrate was cobble with gravel and some sand. The NWI classified Spring Creek as Riverine, Intermittent, Streambed, Temporally Flooded (R4SBA), however field observations and review of aerial photographs indicate that Spring Creek is a perennial stream having a defined Weston Solutions, Inc. Wetland and Waterbody Assessment Report 3-3 June 2023 bed, extensive fringing wetlands, and persistent flow visible in aerial photographs. Based on this field investigation, Spring Creek is now classified as Riverine, Upper Perennial, Unconsolidated Bottom, Cobble-Gravel, Temporally Flooded (R3UB1A). Spring Creek’s perennial flow and connection to Gallatin River via East Gallatin River, meet the criteria for Waters of the United States under the jurisdiction of the USACE. Photographs of the Survey Area are provided in Appendix A. The following table details the stream characteristics of each feature.

As shown on the figures, in the northern portion of the Site, the buildings and Red Wing Drive had been demolished and a second track had been added to the railway. The uplands were generally dominated by canada thistle (Cirsium arvense), kentucky bluegrass (Poa pratensis), timothy grass (Phleum pratense), common dandelion (Taraxacum officinale), and field pennycress (Thlaspi arvense). The upland soils generally consisted of gray and brown sandy loams outside of the riparian area. Uplands within the riparian area were black or dark brown clay loam soils consistent with the observed wetland soils. Uplands predominantly lack wetland hydrology. While some of the Upland data plots exhibited wetland indicators, no data plot exhibited all three vegetation, soil and hydrology indicators. Additional details of Uplands are included in Appendix B – Plots 2, 4, 6, 8, 10, & 12. Weston Solutions, Inc. Wetland and Waterbody Assessment Report 4-7 June 2023 4 SUMMARY The desktop analysis and field investigation were conducted to identify and assess wetlands and waterbodies in the Survey Area. This wetland and waterbody assessment report was prepared as a revision to the May 2022 Wetland and Waterbody Assessment Report. This report further assessed Spring Creek, Mandeville Creek, and associated wetlands within the riparian corridor. The field investigation identified a large wetland waterbody complex covering the entire length of the Survey Area. This large complex included Spring and Mandeville Creeks. Spring and Mandeville Creeks entered the Survey Area at the southern Site boundary. The creeks merged approximately 1200 feet north of the Site boundary. Spring Creek continued north through the Survey Area and exiting. Spring Creek merged with East Gallatin River approximately 1000 feet north of the Site. The area contained within the OHWM of Spring and Mandeville Creeks were 2.32 and 0.35 acres respectively for a total area of approximately 2.67 acres in the Survey Area. Wetlands in the Survey Area were directly connected to Spring and Mandeville Creeks. Wetlands in the Survey Area totaled 8.06 acres. The identified wetlands in the Survey Area we separated into 5 sections (Wetland 1-5), exhibiting slight changes in vegetation cover and topography, often separated by culverts. The wetlands were relatively similar, exhibiting dominant emergent hydrophytic vegetation, thick black hydric soils, and saturation with a high-water table. Spring and Mandeville Creeks were observed to have perennial flow and are located in the Gallatin River Watershed. The wetlands were directly connected to Spring and Mandeville Creeks. The wetlands and waterbodies in the Survey Area meet the criteria for Waters of the United States under the jurisdiction of the USACE. Although the wetlands and waterbodies meet the criteria, only the USACE can make the final Jurisdictional Determination. 5 REFERNCES FEMA, 2021.
