ABSTRACT
Svoboda Ecological Resources (SER) visited the above referenced property on October 7, 2015 to
examine the site for the presence of areas meeting wetland criteria. The wetland boundaries were flagged
on October 7, 2015 and sample data were collected on October 15, 2015. The study parcel is located in
the city of Orono, MN in Hennepin County (Figure 1). One wetland boundary was delineated at this site.
One sample transect was established along the boundary of the wetland area in order to characterize the
soil, vegetation, and existing hydrology within the wetland-to-upland transition zone.
INTRODUCTION
The site includes one parcel, which totals approximately 2.29 acres and is dominated by non-native
deciduous trees and a mowed, manicured lawn. One wetland present on the property was delineated.
Topography is somewhat undulating with the highest elevation located in the center of the parcel.
One residence is located onsite. The surrounding land use is moderately spaced single family homes
mixed within scattered deciduous trees. The North Arm of Lake Minnetonka is located adjacently
west. The identified wetlands were 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 delineate the subject parcel are as 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 boundary. 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
wetland boundaries." "...This Regional Supplement is designed for 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) map, Minnesota Department of Natural Resources 2014
update (Figure 2), Web Soil Survey of Hennepin County map (Figure 3), Minnesota Public
Waters Inventory map (Figure 4), and 2014 aerial photographs were reviewed prior 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. Sample transects were established in representative wetland-to-upland
transition zones in order to characterize the vegetation, soils, and hydrology of the site. Transects
consist of a representative upland sample point, a representative transition sample point and
representative wetland sample point. Information obtained at the sample points can be found on
the field data sheets located in the Technical Documents section.
The wetland boundary was 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, PSS IC, 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 List of Plant Species That Occur in Wetlands —
Region 3 (Sabine 1999).
RESULTS
The National Wetland Inventory indicates the presence of one wetland (PUBF) within the survey
area(Figure 2).
The Web Soil Survey of Hennepin County (Figure 3) identifies two soil map units present on the
subject property. The Lester-Kilkenny complex soils (6-12 percent slopes eroded, and 18-25
percent slopes) are both listed as predominantly non-hydric. Due to the presence of Lake
Minnetonka adjacently west of the subject property, water is listed as a soil map unit onsite as
well. The soil series descriptions are provided in the Technical Documents section.
The Minnesota Department of Natural Resources, State Protected Waters Map (Public Water
Inventory) indicates Lake Minnetonka-North Arm as slightly within the study area(Figure 4).
Site Visit
SER ecologists examined the subject property for areas meeting defined wetland criteria during the
site visit. The area meeting the defined criteria of a wetland was flagged, and the boundary was
determined and delineated. The approximate wetland boundary is outlined in yellow(Figure 5).
Accumulated precipitation prior to the 10/15/15 sampling date shows field work was conducted
under normal conditions, according the Minnesota Climatology Working Group. The months of
September,August, and July received rainfall totals of 3.28", 2.82"and 7.94", respectively.
Precipitation from April 1, 2015 to October 15, 2015 as recorded at the Chanhassen WSFO totaled
24.85"which is 1.61" above normal with average recorded temperatures to date of 62.0 degrees F for
the same period. The average is just slightly above normal by 0.3 degrees F.

We would classify Wetland 1 as a PEMC, Type 2/3, fresh (wet) meadow/shallow marsh. The
wetland vegetation at wetland sample SP 1-1 Wet is dominated by boxelder (Acer negundo,
FAC) in both the tree and sapling strata, as well as green ash (Fraxinus pennsylvanica, FACW)
in the sapling stratum. The herbaceous layer is dominated by Pennsylvania smartweed
(Persicaria pennsylvanica, FACW). Sample point SP 1-1 Up was dominated by American elm
(Ulmus Americana, FACW) and boxelder in the tree stratum, common buckthorn (Rhamnus
cathartica, FAC) in the sapling stratum, and wild ginger (Asarum canadense, FACU) and
bittersweet nightshade (Soanum dulcamara, FAC) in the herbaceous stratum. There is a clear
break in vegetation from the Pennsylvanica smartweed present in the herbaceous layer of the
wetland, to an upland with relatively sparse herbaceous vegetation. This vegetation break was
consistent with a hydrologic change and was therefore based both on the hydrologic change as
well as the vegetation.
Soils at SP 1-1 Wet were silty clay in texture for the entirety of the sample depth. From 0-2
inches soil was IOYR 2/1 in color with no redox. Beginning at 2 inches and continuing through
24 inches, 15 percent redox concentrations appear within the l OYR 2/1 matrix. This meets hydric
soil indicator F6 for Redox Dark Surface. Soils at SP1-1 Up appeared to be disturbed. Soils were
a gravelly loam and very dry/friable. From a depth of 0 to 24 inches, the soil matrix was 10YR
2/2 in color with redox concentrations that were 7.5 YR 5/4 and 5YR 3/4 in color. Although this
meets the hydric soil indicator for F6 (Redox Dark Surface), this is likely a product of the soil
being disturbed rather than as a wetland indicator due to its low moisture content and hydrologic
position.
Sample point 1-1 Wet, which is located near the bottom of a depression, meets the secondary
indicators D2 (Geomorphic Position) and D5 (FAC-Neutral Test). At sample point 1-1 Up,
secondary hydrology indicator D5 is met. However, due to its location on a hillslope near the top
of the hill, SP 1-1 Up fails to meet the Geomorphic Position hydrology indicator.
Detailed soils, vegetation, and hydrology data for the delineated wetland is provided in the data
sheets of the Technical Documents section.
DISCUSSION
SER completed the on-site delineation based on 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 the basin. The wetland boundaries were flagged on
10/7/15 and field data was collected on 10/15/15.
SER personnel examined the subject property for areas meeting defined wetland criteria during
the site visit and delineated the wetlands based on the technical criteria present(Figure 5).
Detailed soils, vegetation and hydrology data are provided in the data sheets of 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.
1* 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.
While the wetland boundaries that SER has delineated are 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 SER has delineated as
wetland. No grading or filling in wetland basins should commence until all 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. It is also 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 only three 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.

seconds N., and long. 93 degrees 38 minutes 41 seconds W.,NAD 27.
RANGE IN CHARACTERISTICS: Depth to free carbonates range from 20 to 60
inches. Gravel of mixed lithology,but dominated by shale fragments, typically make up 2
to 8 percent of the volume of the series control section,but the upper part of the profile in
some pedons contains less than 2 percent gravel. Rounded shale fragments dominate the
coarse sand fraction. Soil saturation occurs above a depth of 40 inches in 6 out of 10
years.

loam, silty clay loam, loam or silt loam. The reaction is moderately acid to neutral.
Some pedons have a thin E horizon.
The Bt horizon has hue of l OYR or 2.5Y, value of 4 or 5, and chroma of 3 to 5. Faint to
prominent Fe concentrations and depletions commonly are above a depth of 40 inches.
Redox depletions do not occur in the upper 10 inches of this horizon. The upper 20
inches of the Bt horizon typically contains 35 to 45 percent clay. B/A clay ratios are 1.2
to 1.4. The Bt horizon is clay loam, silty clay loam, or clay. The reaction strongly acid to
neutral.

loam or loam. The reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Kilkenny soils have plane and convex slopes on gently
sloping to steep end moraines of the Des Moines lobe of the Late Wisconsinan glaciation.
Their slopes range from 2 to 35 percent. They formed in a mantle of clayey glacial till or
flow till and underlying loamy glacial till on moraines. Mean annual temperature ranges
from 45 to 52 degrees F. Mean annual precipitation is about 25 to 32 inches. Frost-free
days range from 145 to 175. Elevation above sea level ranges from 800 to 1500 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Glencoe, Lerdal, Lester,
Le Sueur, Lura, Mazaska, and Shields series. The very poorly drained Glencoe and Lura
soils are in the lower lying drainageways and depressions. The somewhat poorly drained
Lerdal soils are on gently sloping to moderately steep areas. Shields soils are poorly
drained, and are on slightly elevated flats. Mazaska soils are poorly drained, and are on
slightly elevated flats and swales above or within areas of Kilkenny soils. Also, the well
drained Lester soils and the moderately well drained Le Sueur soils are associated in a
few areas.
DRAINAGE AND PERMEABILITY: Moderately well drained. Permeability is
moderately slow. Runoff is medium to very high. A perched seasonal high water table
occurs at depths of 2.5 to 4.0 feet during the period April, May, and June in normal years.
USE AND VEGETATION: Most of these soils are cropped to corn, grain,hay, and
soybeans. Some areas are used for pasture and some are forested. Native vegetation is
mixed prairie and forest species.
DISTRIBUTION AND EXTENT: South central Minnesota and north-central Iowa. The
series is of moderate extent.
