(Morrison-Maierle) for Mitchell Development Group (Client) on the Bozeman Gateway project. The project area consists of Phase 4 of the Bozeman Gateway Development between West Garfield Street and Harmon Stream Blvd. in Bozeman, Montana (Appendix A, Figure 1). The subject property was evaluated for its content of potential jurisdictional wetlands and waterbodies, based on criteria set forth in the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (Environmental Laboratory 2010). Prior to the site visit, Morrison-Maierle reviewed existing project area literature including historical aerial photography, topographic maps, and hydrology data. A subsequent field evaluation was performed to identify hydric soils, hydrology, and hydrophytic vegetation. Vegetation communities were evaluated and documented to delineate wetland and upland boundaries. Based on the wetland delineation presented in this report and the data collected, it is Morrison- Maierle’s professional judgement that no waters of the U.S. were present within the project area. The U.S. Army Corps of Engineers (USACE) and the U.S. Environmental Protection Agency (EPA) are the final authority over the jurisdictional status of both wetlands and waters of the U.S. per Section 404 of the Clean Water Act. The findings discussed in this report are solely the opinion of Morrison-Maierle and have not been verified by the aforementioned regulatory government agencies. Bozeman Gateway Phase 4 Wetland Delineation Page 1 1 Introduction At the request of the Client, Morrison-Maierle completed a wetland delineation on the Bozeman Gateway Phase 4 project. The project area covered approximately 15 acres of land between West Garfield Street and Harmon Stream Blvd. in Bozeman, Montana (Appendix A, Figure 1). This technical report summarizes the findings of the wetland delineation. 2 Methods This wetland delineation 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). The methodology includes sampling procedures for vegetation, hydrology, and soil parameters. Upland data points (UDP) and wetland data points (WDP) were established as needed during the field visit. Sample data points were labeled with an UDP or WDP, followed by the number associated with the data point, (e.g. noted here in bold (UDP 1) to correspond to the sample points for that location. Data for vegetation, hydrology, and soils were recorded in the field and entered on Wetland Determination Data Forms. Corresponding photographs were taken at each data point. Sample points and wetland boundaries (if present) were recorded using a Trimble® Geo 7X™ Global Positioning System (GPS) unit and post-processed to sub-meter accuracy. Locations were then converted to shapefiles uploaded into ArcMap 10.6.1 for display on figures included in Appendix A. 2.1 Vegetation Vegetation at upland and wetland data points was classified based on its wetland indicator status derived from the Montana 2016 State Wetland Plant List (Lichvar et al. 2016). Using the current plant list, vegetation cover qualifies as hydrophytic when over 50% of the dominant plant species have an indicator status of obligate (OBL), facultative wet (FACW), and/or facultative (FAC). FAC plants, such as Canada thistle (Cirsium arvense), are equally likely to occur in wetlands and non- wetlands. Vegetation cover was considered as upland where over 50% of the dominant plant species were classified as upland (UPL), and/or facultative upland (FACU). Plants observed within each data plot were identified using Montana Manual of Vascular Plants (Lesica 2012) along with other reference books. Vegetation nomenclature follows Lichvar et al. (2016) and Lesica (2012). 2.2 Soil Wetlands must meet the qualifications of at least one hydric soil indicator, or meet the definition of a hydric soil (a soil that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part (NRCS 2019a)). Soils at each data point were evaluated and described notating the depth, matrix color, mottle abundance and contrast (if present), texture, etc. (Environmental Laboratory, 1987 and 2010). Bozeman Gateway Phase 4 Wetland Delineation Page 2 Moist matrix color and moist mottle color of the soils were determined utilizing the Munsell Soil Color Chart (Kollmorgan Instruments Corporation, 2009). 2.3 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. 3 Results A wetland delineation of the project area was performed by Morrison-Maierle environmental scientists on August 1, 2019. The vegetation, hydrology, and soil characteristics at each of 2 data points were documented in the field and recorded on Wetland Determination Data Forms for the Western Mountains, Valleys, and Coast Region (Supplement, 2010). 3.1 Vegetation Vegetation communities were evaluated and documented to delineate wetland and upland boundaries. The majority of the project area consists of disturbed vegetation from surrounding commercial development. The northeast corner of the project area consists of a completed stormwater swale with planted grass. No wetland plant communities existed within the investigation area. Upland plants observed included: hoary alyssum (Berteroa incana, NI), orchard grass (Dactylis glomerata, FACU), foxtail barley (Hordeum jubatum, FAC), timothy (Phleum pretense, FAC), and mowed and irrigated lawn grass. The investigation area consisted of disturbed areas for construction of nearby facilities and a drainage swale that no longer receives a direct source of water. The location of all data points are identified on Figure 5 of Appendix A. 3.2 Soil Mapped soil types within the project area were obtained from the Web Soil Survey (NRCS 2019b). One mapped soil was identified in the project area: Meadowcreek loam, 0 to 4 percent slopes (510B) (Appendix A, Figure 3). Soils were analyzed in the field for texture and color using the Munsell Soil Color Charts (Munsell 2009). Soils within the investigation area exhibited a 10YR 2/1 (black) loam matrix. No redox was observed, no water table was encountered. 3.3 Hydrology 3.3.1 Topography The project area lies within the Bozeman, Montana (2017), U.S. Geological Survey (USGS) 7.5- minute Topographic Map. The project area is shown to be gently sloping to flat with elevations at approximately 4,865 feet above sea level (Appendix A, Figure 1). Additionally, a canal is shown to intersect the north end of the project area. During the site evaluation, the elevation and slope of the project area appeared to be consistent with the USGS topographic map. The canal Bozeman Gateway Phase 4 Wetland Delineation Page 3 (Farmers Canal) has been rerouted due to commercial development and no longer traverses the project area. The EPA National Hydrography Dataset Plus (NHDPlus) was referenced to identify waterbodies within and near the project area (EPA 2019). The nearest surface water feature to the project area is the West Gallatin Canal approximately 700 feet to the west. 3.3.2 National Wetland Inventory The U.S. 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 U.S. wetlands. According to the NWI database, two riverine features (R4SBCx and R3UBFx) and one freshwater emergent wetland (PEM1A) features are located in the project area (USFWS 2019). Appendix A, Figure 4 depicts the NWI features in the project vicinity. The site evaluation included an investigation of the areas shown as NWI features. The project area has been significantly disturbed since at least 2006 from surrounding commercial development. The riverine features (Farmers Canal) were re-routed around that time, cutting off any steady source of water that was once provided to the riverine and wetland features. The wetland feature is now a drainage swale that only receives occasional stormwater runoff form surrounding parking areas and streets. This swale did not meet characteristics of a water of the U.S. 3.3.3 Floodplains The project area is located within the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) panel 30031C0812D, effective September 2, 2011. The project area lies within an unprinted panel, therefore there is no flood plain data available (FEMA 2019). 4 Conclusions Based on the results of the wetland delineation performed according to USACE guidelines, it is Morrison-Maierle’s professional judgement that no waters of the U.S. are located within the project area.
