The study parcel is located in the city of Orono, MN in Hennepin County (Figure 1). No wetland boundaries were delineated at this site. One sample point was examined on the east side of the property in order to characterize the soil, vegetation, and existing hydrology within the potential wetland zone. The site examined did not exhibit any wetland indicators. INTRODUCTION The subject parcel at 225 Old Crystal Bay Rd is approximately 5.2 acres. The parcel is dominated by a rolling topography, with a mix of woodlands and open grassy areas. An unoccupied home is located at the east end of the site. The surrounding land use is primarily widely to closely-spaced single family homes to the south and east and widely-spaced homes interspersed with wetlands to the northwest. No potential wetlands were identified. Had any areas with wetland indicators been identified, such areas would have been classified according to the Cowardin et al., the Circular 39 and the Eggers and Reed classification systems and marked with pink "Wetland Delineation" pin flags. The Technical Documents section of this report contains field data sheets, plant indicator status information, soil survey information, and wetland definition information. METHODS The methods used to identify potential wetland areas on the subject parcel are described in the 1987 US Army Corps of Engineers Wetlands Delineation Manual and the 2010 Midwest Regional Supplement Manual. In the 1987 Manual, the methods used were described under the "routine" methods for sites less than 5 acres. This methodology is followed in order to assess whether the three parameters of a wetland are met for areas on the subject parcel. The three parameters required under normal circumstances in order to delineate a wetland are described in the Technical Documents section. The Midwest Regional Supplement Wetland Delineation Manual is also being utilized to increase the accuracy of our wetland boundaries. This addendum to the original 87 Manual was created to address the many regional differences that affect wetlands and the delineation methods used throughout the country. The following explanations are passages from that document. "This Regional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland- delineation procedures. Regional differences in climate, geology, soils, hydrology plant and animal communities, and other factors are important to the identification and functioning of wetlands. These differences cannot be considered adequately in a single national manual. The development of this supplement follows National Academy of Sciences recommendations to increase the regional sensitivity of wetland-delineation methods (National Research Council 1995).The intent of this supplement is to bring the Corps Manual up to date with current knowledge and practice in the region and not to change Svoboda Ecological Resources 225 Old Crystal Bay Road 2014-031-03 1 Sherry Underdahl wetland boundaries." "...This Regional Supplement is designed far use with the current version of the Corps Manual (Environmental Laboratory 1987) and all subsequent versions. Where differences in the two documents occur, this Regional Supplement takes precedence over the Corps Manual for applications in the Midwest Region." National Wetland Inventory (NWI) maps (Figure 2a), Hennepin County Wetland Inventory (HCWI) maps (Figure 2b), 2014 DNR NWI Update maps (Figure 2c), Web Soil Survey of Hennepin County map (Figure 3), Minnesota Public Waters Inventory maps (Figure 4), and 2012 aerial photographs were reviewed priar to the site visit to identify areas that may be wetlands. Areas illustrating evidence of wetland conditions were examined in greater detail during the field survey. Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and used to characterize wetland types and determine wetland boundaries. A sample point was established in a representative potential wetland location in order to characterize the vegetation, soils, and hydrology of the site. Transects may consist of a representative upland sample point and representative wetland sample point unless field conditions indicate otherwise. Information obtained at the sample point can be found on the field data sheets located in the Technical Documents section. If wetland boundaries are identified, they are marked at the site by pink "Wetland Delineation" pin flags. The wetland boundary is considered to be the topographically highest extent of the wetland basin; areas below the staked boundary met the three required wetland criteria while areas above were lacking in one or more of these criteria. Wetlands were classified in accordance with methods described by Cowardin et al. (1979) and used in the NWI (e.g. PEMB, PSS1C, etc.), completed by the U.S. Fish and Wildlife Service. The Circular 39 and Eggers and Reed classification systems are also given. The indicator status of plants, as described in the Technical Documents section, was determined using the National Wetland Plant List (Lichvar, et al. 2014. http://wetla�td pla�zts.u.�ace.ai•m��.ntil�. RESULTS The National Wetland Inventory does not indicate any wetlands in the survey area (Figure 2a). The HCWI also indicates no wetland in the survey area (Figure 2b). The DNR NWI update in 2014, like the original NWI also does not indicate any wetlands in the survey area (Figure 2c). The Web Soil Survey of Hennepin County (Figure 3) identifies three soil map units present on the subject property. They are as follows: Hamel-Glencoe, depressional, complex; Angus loam, morainic; and Shorewood silty clay loam. The Hamel-Glencoe soil is predominantly hydric while the remaining types are predominantly nonhydric. Soil series descriptions are provided in the Technical Documents section. The Minnesota Department of Natural Resources, State Protected Waters Map (Public Waters Inventory) indicates no public waters within the study area(Figure 4). Site Visit SER ecologists examined the subject property for areas potentially meeting jurisdictional wetland criteria during the site visit. No areas meeting the jurisdictional criteria of a wetland were flagged; one area of potential wetland was examined (Figures 5 and 6). Svoboda Ecological Resources 225 Old Crystal Bay Road 2014-031-03 2 Sherry Underdahl Accumulated precipitation since 4/Ol/2014, as recorded at MSP and reported by the USDA National Agricultural Statistics Service in cooperation with the Minnesota Department of Agriculture reports that for the week ended October 12, 2014, was 7.16" above normal. Precipitation for the period 10/06/14 to 10/12/14 was reported to be 0.58" below normal and for the preceding 4 weeks was 0.51" below normal. One area, labeled Area A, was examined to determine if it met wetland requirements. The area is a terraced slope dominated by reed canarygrass (Phalaris arundinacea FACW). There were some wetland species present, a small amount of reed canarygrass mixed in with the bluegrass. However, at sample point SP A in the center of the reed canarygrass, the soil consisted of a lighter-colored loam and was not found to be hydric. Wetland hydrology was not indicated, either, with only one secondary hydrology indicator present, DS (FAC-Neutral Test). While the terrace likely slows down water enough to allow the reed canarygrass to thrive, it doesn't appear to cause an accumulation of water to the degree of forming wetland soils. Detailed soils, vegetation, and hydrology data for the sample point is provided in the data sheet in the Technical Documents section. DISCUSSION SER completed the site examination to search for areas potentially meeting the three required technical criteria as outlined by the 1987 Manual: the presence of hydric soils, a predominance of hydrophytic vegetation, and indicators of wetland hydrology in each basin. The property was examined for the possible presence of wetlands on 10/06/14 and field data for the area in question was collected on 10/09/14. SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit. One potential wetland area was examined however wetland indicators were absent (Figures 5 and 6). Detailed soils, vegetation and hydrology data are provided in the data sheet in the Technical Documents section.A set of figures is provided in the Figures section. RECOMMENDATIONS Activities that impact or could potentially impact wetlands are regulated at several levels of government. In Minnesota, the two primary jurisdictions are covered at the state and federal levels by the provisions of the following legislative actions. i= State jurisdiction by the Wetland Conservation Act of 1991 (WCA) administered by the WCA Local Governmental Unit(LGU). 2* Federal jurisdiction by the Clean Water Act of 1972 and subsequent amendments. Wetland protection is implemented by the Corps of Engineers (Corps)with permit certification issued by the Environmental Protection Agency. The lack of any wetland areas that SER has determined is not official until approved by a WCA approved local government unit (LGU). SER advises the property owner/developer to refrain from any filling, draining, or excavating, or any impact to the area that SER has examined until final review has been completed by the LGU. No grading or filling should commence until all Svoboda Ecological Resources 225 Old Crystal Bay Road 2014-031-03 3 Sherry Underdahl necessary permits have been obtained. Violation of wetland regulations may result in substantial civil and criminal penalties. Local ordinances may regulate wetland modifications such as brush and tree removal and burning in addition to grading and filling. Depending on the location of the property, buffers around the wetland may also be protected.Any activities in the proximity of the wetland should be cleared with appropriate WCA regulatory agencies. Should any weltand areas be determined to exist by the LGU in its review of the site, it is advisable to have the wetland boundary surveyed by a licensed land surveyor. Since the pin flags used along the boundary can be vandalized or inadvertently knocked over, a GPS survey of the flags will assure the permanence of the boundary. The client should also be aware that approved wetland boundaries are typically valid for five years from the date of approval. To avoid project delays associated with wetland regulations, it is essential that you acquire necessary permits from all jurisdictional agencies before initiating activities.A WCA Sequencing form, a WCA and Army Corps of Engineers Replacement Plan Application form, and a DNR permit application are among the materials that you may be required to submit if impacts are proposed for the delineated wetlands. By initiating the permit process as soon as possible, potential costly delays to the project may be avoided. Svoboda Ecological Resources 225 Old Crystal Bay Road 2014-031-03 4 Sherry Underdahl CERTIFICATION Frank Svoboda completed the examination of the site on 10/06/2014 and David Remucal collected the sample point data on 10/09/2014. This site examination was performed according to the procedures described by the US Army Corps of Engineers in the 1987 Wetlands Delineation Manual and the 2010 Midwest Region Supplement Wetland Delineation Manual. The investigative procedure meets the standards and criterion described in these manuals and conforms to the applicable standards and regulations in force at the time the delineation was completed. Report and graphics were prepared by David Remucal (Wetland Ecologist) on this day 10/21/14. The delineation report was reviewed by Frank Svoboda, President of Svoboda Ecological Resources.

RANGE IN CHARACTERISTICS: Depth to free carbonates is 30 to 60 inches or more. The Ap in a few pedons will have small amounts of free carbonates. The thickness of the mollic epipedon ranges from 24 to 80 inches. The control section averages between 22 and 35 percent clay and from 15 to 30 percent fine sand and coarser. Rock fragments of mixed lithology comprise 0 to 5 percent of the volume of the A and B horizons and 2 to 8 percent of the C horizon. Some pedons have an 0 horizon up to 6 inches in thickness. A stratified substratum phase is recognized with silt loam, sand, sandy loam, and loamy sand textures below 40inches. The Ap or A horizon has hue of lOYR to SY or neutral, value of 2 or 3, and chroma of 0 or 1. It is clay loam, silty clay loam, or loam with 25 to 35 percent clay. Ponded phases may have mucky modifiers. It is commonly neutral but ranges from slightly alkaline to slightly acid. AB horizon has colors and textures similar to the A and Bg horizons. The Bg horizon has hue of SY or 2.SY, value of 2 to 5, and chroma of 1 or 2. Dark colored tongues from the A horizon range from few to common. It is loam, clay loam or silty clay loam. Near the center of some depressions, some pedons have B horizons that have a slight clay increase relative to the A horizons. It is neutral to slightly alkaline, but in some pedons the lower part of the B horizon is slightly alkaline with slight effervescence. The Bg horizon is absent in some pedons. The Cg horizon has hue of SY ar 2.SY, value of 4 to 6, and chroma of 1 to 4. It is loam, clay loam or silty clay loam. It is slightly alkaline, with weak or strong effervescence. Calcium carbonate segregations are present in some pedons. COMPETING SERIES: These are the Coland, Comfi�ey, Delft, Giclow, James Canyon, Keddie, Kinlmerlin�;, Koniler, McClave, Peo11, Romnell, Shalldep, and Wenas series. Coland and Comfrey soils do not have rock fragments in their control sections. In addition, Coland soils are deeper to free carbonates. Delft soils are poorly drained, are not in closed depressions, have prismatic structure in subsoil, and do not have tongues of the A horizon in the Bg horizon. Gielow, James Canyon, Keddie, Kimmerling, Konner, McClave, Peoh, and Wenas soils are drier in the soil moisture control section during the 120 days following the summer solstice. Romnell soils contain appreciable amounts of gypsum in their sola. Shandep soils do not have tongues of A horizon in the Bg horizon and have a coarse textured 2C horizon. GEOGRAPHIC SETTING: Glencoe soils typically are in closed depressions or low gradient swales within the Des Moines lobe of the Late Wisconsinan glaciation. The Glencoe soils are formed in loamy colluvial sediments and loamy glacial till. Mean annual temperature ranges from 45 to 52 degrees F. Mean annual precipitation ranges from 25 to 32 inches. The frost free days range from 124 to 172. The elevation above sea level range from 700 to 1600 feet. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Canisteo, Clarion, Hart�s, Nicollet, and Webster soils. The well drained Clarion soils are on the sloping uplands. Somewhat poorly drained Nicollet and the poorly drained Canisteo, Webster, and Harps soils are on nearly level to gently undulating slopes. All the above have mollic epipedons less than 24 inches thick. In addition, the Canisteo and Harps soils contain free carbonates throughout. The Glencoe soils also are associated with the Hayden and Lester soils and their respective topographic associates in some places. DRAINAGE AND PERMEABILITY: Very poorly drained. Surface runoff is negligible. Permeability is moderate or moderately slow. USE AND VEGETATION: Mostly drained and cropped to corn and soybeans. Native vegetation was a wet site plant community of the tall grass prairie plant formation. DISTRIBUTION AND EXTENT: South-central Minnesota and possibly north- central Iowa. Large extent. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota SERIES ESTABLISHED: Dakota County, Minnesota, 1945. REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon-the zone from the surface to a depth of 35 inches (Ap, A, and ABg horizons); cumulic subgroup-mollic epipedon is more than 24 inches thick; aquic moisture regime- low chroma immediately below the A horizons.

It is moderately acid to neutral. The C horizon has hue of a 2.SY or SY, value of 4 to 6, chroma of 1 or 2. It is loam or clay loam. It is slightly alkaline or moderately alkaline. The clay content ranges from 18 to 32 percent and the total sand content ranges from 25 to 45 percent. COMPETING SERIES: These are the Alvada, B�, Berville, Brookston, Buntin�;��ille, Clackamas, Cordova, Forestcitv, Jameston, Maren�o, Mill�rove, Navan, Nosoni, Rensselaer, and Westland soils. The Alvada series (Tentative - OH) is not in the OSD file at this time. The Barry, Berville, Brookston, Cordova, Marengo, Millgrove, Navan, Rensselaer, and Westland soils have a mollic epipedon that is less than 24 inches thick. The Buntingville soils have carbonates at depths of less than 20 inches. The Clackamas and Nosoni soils lack free carbonates in the series control section. The Forestcity soils have 45 to 65 percent sand and 10 to 18 percent clay in the underlying material. The Jamcstown soils formed in a firm and very firm till associated with the Iowan Erosional surface. GEOGRAPHIC SETTING: Hamel soils have concave slopes in swales, rims of closed depressions, foot and toe slopes, and upper drainageways below sloping to very steep slopes. Slope gradients are 1 to 4 percent. Hamel soils formed in slope colluvium and glacial till of Late Wisconsinan Age. Mean annual air temperature is about 45 to 48 degrees F. Mean annual precipitation is about 25 to 30 inches. Frost free days range from 125 to 165. Elevation above sea level ranges from 700 to 1600 feet. GEOGRAPffiCALLY ASSOCIATED SOILS: These are principally the Ha•� and Lestei- soils. These soils are well drained and are on the higher lying, gently sloping to very steep slopes. DRAINAGE AND PERMEABILITY: Poorly drained and somewhat poorly drained. Surface runoff is low or moderately low. Permeability is moderately slow. The apparent seasonal high water table is at .5 to 1.5 feet for the poorly drained phase and 1.5 to 2.5 feet for the somewhat poorly drained phase during spring in normal years. USE AND VEGETATION: Most of this soil is cropped to corn, hay, soybeans, and small grains. However, significant areas are in pasture and forest. Native vegetation is mixed wet prairie grasses and deciduous forest. DISTRIBUTION AND EXTENT: Primarily in the southeast one-quarter of Minnesota in the timbered, hilly, "gray" till region. Moderately extensive. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota SERIES ESTABLISHED: Hennepin County, Minnesota, 1969. REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon-the zone from the surface to a depth of 40 inches (Ap, A, AB and Btgl); argillic horizon-the zone from 24 to 46 inches (Btgl, Btg2,). Type location moved from Hennepin County, Mn. to Wright County, Mn., 11/96 to better exemplify the series concept. A somewhat poorly drained overwash phase is recognized that has 8 to 20 inches of colluvium over the original dark colored surface. ADDITIONAL DATA: Refer to MAES Central File Code No. 785 for results of some laboratory analysis of this series. P oto Lo g 22 S O ld C stal B a Rd S rY Y Orono MN � ; \ ,y���� S 6 A , r.�.
