INTRODUCTION The 1.76-acre 4035 Dahl Road Parcel was inspected on June 6, 2017 for the presence and extent of wetland. The property was located in Section 7, Township 117N,Range 23W, Orono, Hennepin County,Minnesota. Generally, the site location was south of Dahl Road and east of North Arm Drive (Figure 1). The site limits corresponded to Hennepin County PID 0711723140003. � The majority of the site was manicured lawn with scattered hardwood and evergreen trees. One single-family home was present in the eastem portion of the property. Adjacent land use was primarily single-family homes, forested area, and Lake Minnetonka. The topography was lowest near the western edge of the site with a bottom elevation of 986 feet msl(at Wetland 1) and rose in elevation to the east with a high point at 1412 feet msl. One depressional wetland was identified and delineated within the site boundaries (Figure 2). II. METHODS 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 were located by surveyors from Lot Surveys Company, Inc. Soils,vegetation, and hydrology were documented at a representative location 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, a 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. Soils were characterized to a minimum depth of 24 inches (unless otherwise noted)using a Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources Conservation Service(NRCS) in cooperation with the National Technical Committee for Hydric Soils, Version 8.1, 2017). Mapped soils are separated into five classes based on the percent composition of hydric components and the Hydric Rating by Map Unit color classes utilized on 2 Web Soil Survey. The five classes include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric components),Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric(1 to 32 percent hydric components), and Non- Hydric (less than one percent hydric components). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2016 National Wetland Plant List(U.S. Army Corps of Engineers 2016. National Wetland Plant List, version 3.2,https://wetland�lants.usace.army.mil Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH). III. RESULTS Review of NWI. Soils,DNR and NHD Information The National Wetlands Inventory(NWI) (Minnesota Geospatial Commons 2009-2014 and U.S. Fish and Wildlife Service) showed one PEM1C wetland mapped within the property(Figure 3). The Soil Survey(USDA NRCS 2015) showed Cordova loam as the hydric soil type present within the review area. Soil types mapped on the property are listed in Table 2 and a map showing soil types is included in Figure 4. The Hydric Soil Report—Component List is included in Appendiz A. Table 2. Soil types mapped on the 4035 Dahl Road Parcel Map unit s mbol Ma unit name Rating L23A Cordova loam,0 to 2 ercent slo es Predominantly Hydric L40B Angus-Kilkenn com lex,2 to 6 rcent slo es Prediminantl Non-H dric Lester-Kilkenny complex,6 to 12 percent slopes, L41 C2 eroded Prediminantl Non-Hydric Lester-Kilkenny complex, 12 to 18 percent slopes, L41 D2 eroded Prediminantly Non-Hydric L41E Lester-Kilkenny complex, 18 to 25 ercent slo es Prediminantly Non-Hydric The Minnesota DNR Public Waters Inventory(Minnesota Department of Natural Resources 2015) showed DNR Public Water 27-133-13P (Minnetonka-North Arm) approximately 500' north of the property(Figure 5). The National Hydrography Dataset(NHD) (U.S. Geological Survey 2015) showed one Lake/Pond directly south of the property and one Lake/Pond approximately 500' north of the property(Lake Minnetonka) (Figure 6). 3 Wetland Determinations and Delineations Potential wetlands were evaluated in greater detail during field observations on June 6, 2017. One (1)wetland was identified and delineated on the subject parcel (Figure 2). Corresponding data forms are included in Appendix A. The following description of the wetland and adjacent upland reflects conditions observed at the time of the field visit. At that time precipitation totals were above normal based on available 30-day rolling precipitation data, and climatic conditions were wet based on the three-month antecedent conditions (March,April, May) (Appendiz B). Vegetation was actively growing during the site visit. A survey of the site provided by Gronberg &Associates, Inc. is provided in Appendiz C. Wetland 1 was a Type 3 (PEM 1 C) shallow marsh dominated by reed canary grass with cattail species observed in the center of the basin. Saturation was observed at 14"below the soil surface with no free water present in the wetland sample boring. Additional secondary indicators included Geomorphic Position and FAC-Neutral Test. Wetland 1 was located along the southwestern edge of the property and extended offsite to the south and totaled 0.015 acres in size within site boundaries. The adjacent upland was dominated by Timothy, Canada thistle, and Kentucky bluegrass. No primary or secondary hydrology indicators were observed in the upland. The delineated boundary followed an abrupt change in topography, was placed along the transition from wetland to upland vegetation, where soil transitioned from hydric to non-hydric, and where hydrology indicators were no longer present. Wetland 1 was indicated on the NWI as a PEM 1 C wetland and the soil survey showed Cordova loam (hydric) as the soil types present within the review area. Wetland 1 extended off the property to the south. Additional Areas No additional wetlands were indicated on the NWI map. Hydric soil is mapped north of Wetland 1, however, the upland sample point confirmed this area was not wetland. No additional areas exhibiting inundation or supporting wetland vegetation were observed during field observation. 4 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. Delineation Completed by: Ben Carlson.

This list can help in planning land uses; however, onsite investigation is recommended to determine the hydric soils on a specific site (National Research Council, 1995; Hurt and others, 2002). The three essential characteristics of wetlands are hydrophytic vegetation, hydric soils, and wetland hydrology (Cowardin and others, 1979; U.S. Army Corps of Engineers, 1987; National Research Council, 1995; Tiner, 1985). Criteria for all of the characteristics must be met for areas to be identified as wetlands. Undrained hydric soils that have natural vegetation should support a dominant population of ecological wetland plant species. Hydric soils that have been converted to other uses should be capable of being restored to wetlands. Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS)as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). These soils, under natural conditions, are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation. The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil Taxonomy" (Soil Survey Staff, 1999)and "Keys to Soil Taxonomy" (Soil Survey Staff, 2006)and in the "Soil Survey Manual" (Soil Survey Division Staff, 1993). If soils are wet enough for a long enough period of time to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the United States" (Hurt and Vasilas, 2006). Hydric soils are identified by examining and describing the soil to a depth of about 20 inches. This depth may be greater if determination of an appropriate indicator so requires. It is always recommended that soils be excavated and described to the depth necessary for an understanding of the redoximorphic processes. Then, using the completed soil descriptions, soil scientists can compare the soil features required by each indicator and specify which indicators have been matched with the conditions observed in the soil. The soil can be identified as a hydric soil if at least one of the approved indicators is present. Map units that are dominantly made up of hydric soils may have small areas, or inclusions, of nonhydric soils in the higher positions on the landform, and map units dominantly made up of nonhydric soils may have inclusions of hydric soils in the lower positions on the landform. The criteria for hydric soils are represented by codes in the table (for example, 2). Definitions for the codes are as follows: iiNatural Resources Web Soil Survey 7/18/2017 Conservation Service National Cooperative Soil Survey Page 1 of 3 Hydric Soil List-All Components--Hennepin County, Minnesota 1.
