Section , T.29 N., R.20 W. PID# 2903220320011 Washington County, Minnesota As authorized by Paul Bruggeman, Earth Science Associates, Inc. (ESA) has performed a wetland delineation on the above referenced parcel (See Figure 1, Site Locator Map). A new home is proposed for construction to replace the derelict lake cabin. 2.0 METHODS Wetlands are areas which meet certain technical criteria for wetland in accordance with the 1987 Army Corps of Engineers Wetland Delineation Manual, Corps Supplements, and current Guidance Documents. ESA has performed a routine level 1 and 2 delineation on this site. The findings presented here are based on review of existing information followed by field investigation. Three essential characteristics are required for an area to be defined as a wetland: 1) hydrophytic vegetation; 2) hydric soils; and 3) wetland hydrology. All three of these characteristics must be met, with few exceptions, for an area to be classified as a wetland. Wetland delineation methods utilized for this project include both off-site and on-site procedures. Off-site procedures consist of reviewing existing information, available maps and aerial photos, as required. This is followed with a site visit. Samples of soil and vegetation are examined in order to make an on-site determination of vegetation, soils, and hydrology. The attached wetland determination data forms document the on-site observations. 3.0 RESULTS 3.1 Review of existing information Existing information regarding the possible presence of wetland on this site was reviewed prior to the site visit and is summarized as follows: 1.The USGS 7.5-minute topographic series map (Figure 3) provides general indications of landforms, vegetative cover, and waterways. The subject property is on the Hugo, Minnesota quadrangle, created in 1993. The USGS map indicates wetland east part of the site. South of the site is land at a similar elevation as Big Marine Lake. 2.The NRCS soils map of the subject property (Figure 4) indicates several soil mapping units on the site The Soil Survey of Washington and Ramsey Counties, Minnesota was issued in April 1980. Major field work for this soil survey was performed in the period 1973-77, and soil names and descriptions approved in 1977. The current on-line soil survey reflects conditions encountered at that time, although some of the nomenclature has been updated. Figure 4 presents shaded hydric ratings of the soil mapping units. An NRCS hydric soil ratings report is also attached. Soil mapping units rated Not Hydric (0%) are mapping units 158D – Zimmerman loamy fine, sand 12 to 25 percent slopes, and 1033 – Udifluvents, around the perimeter of the site. Mapping unit 158C –Zimmerman fine sand, 6 to 12 percent slopes, on the interior part of the site, is rated 1 to 32 percent hydric. Soils rated mostly hydric indicate a higher likelihood of wetlands. 3.The National Wetlands Inventory (NWI) Map (Figure 5) was prepared by the U. S. Fish and Wildlife Service in 1992 and was updated in 2013 by the Minnesota DNR. Wetland areas here are described in accordance with Fish and Wildlife Service Circular 39 (Shaw and Fredine 1971). These maps are based primarily on aerial reconnaissance. A wetland key is attached. Wetland near the west property line is mapped PEM1C. Wetland near the south property line is mapped PEM1F. 4.Work in PWI (Public Waters Inventory) areas require special permit from the Minnesota DNR (Figure 6). The DNR Water Permit Programs Unit oversees the administration of the original public waters inventory conducted in the late 1970's. Public waters wetlands include all type 3, type 4, and type 5 wetlands (as defined in U.S. Fish and Wildlife Service Circular No. 39, 1971 edition) that are 10 acres or more in size in unincorporated areas or 2.5 acres or more in size in incorporated areas (Minnesota Statutes Section 103G.005, subd. 17b, Wetland Type). Big Marine Lake, located south of the south property line, is Public Water Basin 82005204. 3.2 Site Conditions Antecedent Moisture Conditions: Consultation of the Wetland Delineation Precipitation Data Retrieval from a Gridded Database from the Minnesota Climatology Working Group (http://climate.umn.edu/gridded_data/precip/wetland/wetland.asp). For each month of each year, monthly precipitation totals are estimated for grid nodes at regularly spaced (10 kilometers) intervals (see map at right). The estimates are derived using a stochastic interpolation technique called "Kriging", which makes use of the irregularly spaced data in the vicinity of the node to assign it a value. A precipitation total is then calculated for every grid node, for every month. Once the grids are created, the calculation of long-term summary statistics such as normals and percentiles can be performed on each grid node. The attached Precipitation Documentation Worksheet summarizes the prior three months of precipitation data and weighs it according to current USDA/ACOE/BWSR standards. Actual monthly precipitation totals for the most recent month(s) (attached) are used on the worksheet in cases where the kriging results are not yet available. The precipitation data indicates the antecedent moisture condition was dry at the time of the site visit. Field Conditions: The site was visited Monday, July 26th, 2021. The weather was sunny, breezy and humid at 85*F; the growing season in full swing. 3.3 Findings Upland The interior of the property is rolling with mature cedar trees and Kentucky bluegrass lawn. The west and south perimeters of the site slope steeply downward. West of the site is a cattail marsh. A narrow strip along the south edge lies adjacent to Big Marine Lake. Wetland: Wetland areas are shown on Figure 2, the Wetland Delineation Site Diagram, which is overlain on digital photography. The attached Army Corps of Engineers Wetland Determination Data document vegetation, soils and hydrology encountered in both wetland and upland areas. Specific wetland areas are described in accordance with: 1. Fish and Wildlife Service Circular 39 (Shaw and Fredine 1971) 2. Classification of Wetlands and Deep Water Habitats of the United States (Cowardin et al. 1979) 3. Wetland Plants and Plant Communities of Minnesota and Wisconsin (Eggers and Reed, 3rd Edition, 2011) Wetland – Edge of Big Marine Lake  Circular 39: Type 5  Cowardin: PEM1F  Eggers and Reed: Shallow open water The lake edge contains broad leaf cattail a peat soil along much of the shore. Oridinary high water level (OHW) is at 942.2 feet elevation. The wetland boundary, based on the contours on the base map from Washington County (Figure 2), lies at or near the OHW. Other Aquatic Resources: Drainage from the lake generally flows eastward, to join the St. Croix, which flows southward to join the Mississippi. 4.0 STANDARD OF CARE The opinions presented in this report are based on information collected during the course of this study and represent Earth Science Associates’ professional opinion and, as such, are not a guarantee.

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: Hydric Soil List - All Components---Washington County, Minnesota Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 9/13/2021 Page 1 of 3 1.All Histels except for Folistels, and Histosols except for Folists. 2.Soils in Aquic suborders, great groups, or subgroups, Albolls suborder, Historthels great group, Histoturbels great group, Pachic subgroups, or Cumulic subgroups that: A.Based on the range of characteristics for the soil series, will at least in part meet one or more Field Indicators of Hydric Soils in the United States, or B.Show evidence that the soil meets the definition of a hydric soil; 3.Soils that are frequently ponded for long or very long duration during the growing season.
