(KES Project No. 2015-036) June 8, 2015 1 WETLAND DELINEATION SUMMARY  The 1150 Homestead Trail Property was inspected on April 18, 2015 for the presence and extent of wetland; the property is approximately 3.9 acres.  The NWI-map showed one PEM1Bd wetland within the property.  The soil survey showed Cordova and Hamel as the hydric soil types present within the review area.  The DNR Public Waters map showed no DNR Protected Waters within 1000’ of the property.  One Type 2 (PEM1Bd) wet meadow wetland was delineated adjacent to the review area, however, the wetland lies outside of the parcel boundary. 2 1150 Homestead Trail Orono, Minnesota Wetland Delineation Report I. INTRODUCTION The approximately 3.9 acre 1150 Homestead Trail Property was inspected on April 18, 2015 for the presence and extent of wetland. The property was located in Section 28, Township 118N, Range 23W, Orono, Hennepin County, Minnesota. Generally the site location was west of Homestead Trail and north of County Road 6 (Figure 1). The site limits corresponded to Hennepin County PID 2811823320001. The site was dominated by manicured lawn with scattered hardwood and coniferous trees throughout the site. A single-family home and garage structures were located near the southern portion of the site. Adjacent land use was primarily single-family homes and agricultural land with a large wetland complex to the northwest of the site. The site slopped from south to north with elevations ranging from 1016’ at the south end to 976’ at the north end. One depressional wetland was identified and delineated northwest of the parcel boundary (Figure 2). II. METHODS Wetlands were identified using Routine Determination methodology described in the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region (Version 2.0) as required by Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetlands, which met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were marked with pin flags and were located by Sathre-Bergquist land surveyors. Soils, vegetation, and hydrology were documented at representative locations along the wetland- upland boundary. Plant species dominance was estimated based on the percent aerial or basal coverage visually estimated within a 30-foot radius for trees and vines, 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type being sampled. Soils were characterized to a minimum depth of 18-24 inches (unless otherwise noted) utilizing Munsell Soil Color Charts and standard soil texturing methodology. Hydric soil indicators used in reporting are from the NTCHS Field Indicators of Hydric Soils in the United States (USDA Natural Resources Conservation Service Version 7, 2010) which are commonly found in the Midwest. 3 Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2014 National Wetland Plant List (Lichvar, R.W. and Kartesz, J.T. 2009. North American Digital Flora: National Wetland Plant List, version 2.4.0 (https://wetland_plants.usace.army.mil). U.S. Army Corps of Engineers, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH, and BONAP, Chapel Hill, NC.) III. RESULTS Review of NWI, Soils, and DNR Information The National Wetland Inventory Map (NWI) (Excelsior/Hamel Quadrangles, MN DNR 2013) showed one PEM1Bd wetland within the property (Figure 3). The Soil Survey of Hennepin County, Minnesota (http://soils.usda.gov/survey/geography/ssurgo/) showed Cordova and Hamel as the hydric soil types present within the review area. A soils map indicating the soil types present within the parcel is included on Figure 4 The DNR Public Waters Map, Hennepin County (http://deli.dnr.state.mn.us/) showed no DNR Public Waters within 1000’ of the property (Figure 5). Wetland Determinations and Delineations Potential wetlands were evaluated in greater detail during field observations on April 18, 2015. One (1) wetland was identified adjacent to the subject site (Figure 2). Corresponding data forms are included in Appendix A. The following description of the wetland and its adjacent upland reflects conditions observed at the time of the field visit. At that time precipitation conditions were normal based on available 30-day rolling precipitation data and dry based on the three- month antecedent conditions (January, February, March) (Appendix B). A survey of the wetland boundary by Sathre-Bergquist is included in Appendix C. Wetland 1 was a Type 2 (PEM1Bd) wet meadow. The wetland was dominated by a fringe of reed canary grass with cattail present north of the wetland fringe. Saturation was observed near the surface at the sample point location with free water observed 16” below the soil surface. Adjacent upland at the sample location was dominated by box elder trees, common buckthorn shrubs, and reed canary grass and common burdock. The delineated boundary followed an abrupt change in topography and was placed along the transition zone from wetland to upland plant communities, where hydrology indicators were no longer present, and the transition from hydric to non-hydric soils. Wetland 1 was indicated on the NWI map as a PEM1Bd wetland and was located in an area of mapped Hamel (hydric) on the soil survey. According to the survey provided by Sathre-Bergquist, the delineated wetland lies outside the property boundary. 4 Other Areas The NWI map indicates no additional wetland on the property. Cordova and Hamel (hydric) soil is mapped throughout much of the site however, the site is dominated by manicured lawn and much of the site is significantly higher than the identified wetland area (a 40’ drop in elevation to the wetland). No other areas with wetland vegetation or hydrology were observed on the site. IV. CERTIFICATION OF DELINEATION The procedures utilized in the described delineation are based on the COE 1987 Wetland Delineation Manual as required by Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Both the delineation and report were conducted in compliance with regulatory standards in place at the time the work was completed. All site boundaries indicated on figures within this report are approximate and do not constitute an official survey product.
