1795 Fox Street Wetland Delineation Report 2. OVERVIEW The 28.22-acre property at 1795 Fox Street was inspected on September 27, 2017 for the presence and extent of wetland. The property was located in the SW 'A of Section 3 and the NW ''A of Section 10, Township 117 North, Range 23 West, City of Orono, Hennepin County, Minnesota. The site was situated at the end of an 830-foot long cul-de-sac that extends south off of Fox Street from a point 0.75 mile west of Shoreline Drive (CSAH 15) (Figure 1). The property corresponded to Hennepin County PID 03-117-23-44-0006. The site included part of a large shallow marsh dominated by cattails with a fringe of reed canary grass. The cattail marsh curved around a partially wooded upland peninsula with green ash, common buckthorn, black walnut, and white cedar, and some grassland dominated by orchard grass, Kentucky bluegrass, and smooth brome. The large cattail marsh is DNR Public Waters Wetland 27-859W and it includes a DNR Public Watercourse that drains southeast toward Tanager Lake. Site topography was highest near the center of the peninsula at 946 feet above msl, and lowest in the wetland at an elevation of about 930. The property was bordered on the southeast by the Hennepin County Regional Trail, on the west by cattail marsh, on the north by unoccupied residential lots, and on the east by cattail marsh. One wetland was delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown on Figure 2. The property also included a stormwater pond that was constructed in 2009, the same year that the cul-de-sac was constructed. Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for: (1) a wetland boundary and type determination under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence and a Preliminary Jurisdictional Determinations (PJD) under Section 404 of the Federal Clean Water Act. 3. METHODS 3.1 Wetland Delineation Wetlands were identified using the Routine Determination method described in the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region (Version 2.0) as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetland that met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were marked with pin flags that will be located by Gronberg& Associates Land Surveyors. Approximate wetland boundaries shown on Figure 2 are based on a previous wetland 2
