Matt Ekstrom, Project Manager 2880 Technology Boulevard West Bozeman, Montana 59718 Subject: Catron Crossing – Wetland/Waters Delineation Amendment Dear Matt: At the request of Morrison-Maierle Inc. (MMI), a professional wetland scientist with Power Engineers, Inc. (POWER) examined an approximately 2.75-acre site (Project Area) on September 6, 2017, for the presence and extent of wetlands and waterways. This Project Area is located along East Valley Center Drive and is associated with the proposed commercial development identified as Catron Crossing. This Project Area was delineated due to comments received by MMI from the City of Bozeman regarding the Catron Crossing watercourse setback variance. The Project Area is located in the south-central portions of the southwest and southeast quarters of Section 26, Township 2 South, Range 5 East, Bozeman, Gallatin County, Montana. Using the Routine Level 2 Determination Method as outlined in the 1987 U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual and subsequent methodologies outlined in the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0), one wetland and one non-wetland waterway (Catron Creek) were identified and delineated within the Project Area. The delineated features are identified on the attached map (Figure 1) and associated wetland/upland data sheets and photographs of the delineated features are provided. Wetland 3 The riparian wetland fringe associated with Catron Creek was delineated as wetland (W) 3 and is identified on the attached figure (Figure 1). Within the Project area, W3 totaled 1.23 acres. The wetland hydrology indicators for W3 included a high water table (observed at four inches below the soil surface), saturation in the upper 12 inches of the soil profile (observed at the soil surface), oxidized rhizospheres along living roots, geomorphic position, drainage patterns, and a positive FAC-Neutral test. The dominant vegetation observed within the wetland included narrow-leaf willow (Salix exigua, FACW) and Northwest Territory sedge (Carex utriculata, OBL) with other vegetation observed including broad-leaf cattail (Typha latifolia, OBL), pale-yellow touch-me-not (Impatiens aurella, FACW), American brooklime (Veronica americana, OBL), and fringed willowherb (Epilobium ciliatum, FACW). The hydrophytic vegetation indicators included a positive dominance test and prevalence index within the range indicating the presence of hydrophytic vegetation. The hydric soil indicator is redox dark surface based on observations of a 10YR 2/1 soil layer, 0 to 24 inches with ten percent redoximorphic concentrations (10Y/R 5/6) in the soil matrix. BOI 199-100 (PER 01) MM (9/12/2017) 146446 PAGE 2 OF 2 The wetland/upland boundary primarily follows a change in topography and vegetation from wetland- to upland-dominated species. The observed upland vegetation was dominated by smooth brome (Bromus inermis, UPL), common snowberry (Symphoricarpos albus, FACU), and prickly rose (Rosa acicularis, FACU) with other upland vegetation including Canada thistle (Cirsium arvense, FAC), common tansy (Tanacetum vulgare, FACU), American licorice (Glycyrrhiza lepidota, FAC), and quack grass (Elymus repens, FAC). W3 was preliminarily determined to be jurisdictional based on an observed hydrologic connection to the East Gallatin River north of the Project area. Catron Creek Within the Project area, the ordinary high water mark of Catron Creek was delineated and the stream totaled 2,171 linear feet and 0.20 acre. The average wetted width of the stream was observed to be approximately 4.0 feet. If additional project-related activities will result in impacts to these delineated features, permitting requirements will include a Section 404 of the Clean Water Act permit through the U.S. Army Corps of Engineers, a Montana Natural Streambed and Land Preservation Act 310 permit through the Gallatin Conservation District, a 401 Water Quality Certification through the Montana Department of Environmental Quality (MDEQ), and potentially a 318 authorization for short-term turbidity through MDEQ. If you have any questions regarding the information being provided, please contact me at (208) 659-8403. Sincerely, Erik S.
