Executive Summary
ISG completed a wetland investigation within a .19 acre project area for future residential development
by the land owners at 3670 Togo Road, on June 21, 2016 (as shown on the attached Figures).
This wetland investigation was performed in accordance with the 1987 US Army Corps of Engineers
Wetland Delineation Manual and the 2010 Midwest Regional Supplement, and all applicable supporting
documents for areas meeting wetland criteria for a routine wetland delineation in accordance to the MN
Wetland Conservation Act and the US Army Corps of Engineers Section 404 Program.
Vegetation, soil and hydrology sampling have been completed on all potential wetland areas within the
project area. Wetland determinations were based on the three required technical criteria: occurrence
of hydric soil, predominance of hydrophytic vegetation, and the presence of one primary and/or two
secondary indicators of wetland hydrology. Potential wetland areas (mapped hydric soils, NWI
signatures, and low depressional areas) were investigated on-site and delineated as upland.
One (1) wetland was delineated during the field investigation. The delineated wetland is a Type 3
Shallow Marsh. Adjacent upland area is predominantly rural residences.
Project Description
INTRODUCTION
ISG was retained to identify and delineate all wetland areas that exist within the project boundaries.
The wetland investigation boundary (project area) encompasses a .19 acre area located at 3670 Togo
Road, in Orono, Minnesota.
The purpose of the wetland investigation is to accurately identify wetland areas onsite so that they can
be incorporated into plans for the future development of the property.
This report is intended to facilitate any regulatory discussions of Wetland Conservation Act and Clean
Water Act Section 10/404 permitting for this project.
LOCATION
The project area is located at 3670 Togo Road, Section 17,T117N, R23W, in the city of Orono, Minnesota
(See Appendix A for a location map). The site is located within an Unknown Minor Watershed (20119)
and the Mississippi River-Twin Cities Major Watershed (20). The topography of the site is relatively flat.
Site elevation ranges from approximately 932' to 936' above msl. At the time of this delineation, the
investigation area was composed of residential areas.
3670 Togo Road, Orono, MN Page 1
SURROUNDING PROPERTIES
The project site is located in a residential landscape, with Lake Minnetonka and its associated bays in
the area. The investigation area is located along the north side of Togo Road, west of Shadywood Road
and southeast of Sunset Drive.
Definitions + Methodology
This investigation was performed in accordance with the US Army Corps of Engineers 1987 Wetland
Delineation Manual and the 2010 Midwest Regional Supplement, and all applicable supporting
documents for areas meeting wetland criteria for a routine wetland delineation in accordance to the
Minnesota Wetland Conservation Act and the US Army Corps of Engineers Section 404 Program. The
following definitions, diagnostic environmental characteristics, and the methodology used is based on
the mandatory technical criteria for the identification and delineation of wetlands.
WETLANDS DEFINITION
As defined in 33 CFR Part 328, Section 3,the term wetlands is defined as: Those areas that are inundated
or saturated by surface or ground water at a frequency and duration sufficient to support, and that
under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated
soil conditions. The frequency and duration of saturation may vary by geographical region, and is largely
dependent upon climatic conditions. Wetlands generally include swamps, marshes, bogs, and similar
areas.
Wetlands have the following general diagnostic environmental characteristics:
Hydrophytic Vegetation
The wetland vegetation criterion is satisfied when the prevalent vegetation consists of plant species
adapted to inundation or substrates periodically deficient in oxygen as a result of prolonged
saturation. Specifically,this includes plant communities that under normal circumstances have more
than 50% of the composition of the dominant species from all strata ranked with an indicator status
as obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC) species.
3670 Togo Road, Orono, MN Page 2
The indicator status for individual plants as defined by the updated 2016 Minnesota National Wetland
Plant List are identified and described in the following table:
Table 1. Vegetation Indicator Categories
Indicator -. . Occurrence
Obligate (OBL) Almost always
Facultative Wetland (FACW) Usually
Facultative (FAC) Equally likely to occur in uplands
Facultative Upland (FACU) Rarely
Upland (UPL) Almost never
Hydric Soil
A hydric soil is a soil formed under conditions of saturation, flooding, or ponding long enough during
the growing season to develop anaerobic conditions in the upper part. Examples of hydric soil
indicators include: the accumulation of organic matter, low-chroma soil matrices, gleying, redox
concentrations, redox depletions, and hydrogen sulfide odor.
Wetland Hydrology
According to the 1987 manual, wetland hydrology is present when the area is inundated either
permanently or periodically at mean water depths less than or equal to 6.6 feet, or the soil is
saturated to the surface at some time during the growing season. The Midwest Regional Supplement
requires fourteen (14) or more consecutive days of flooding or ponding, or a water table of twelve
(12) inches (30 cm) or less below the soil surface, during the growing season at a minimum
frequency of five (5) years in ten (10) (50% or higher probability) to satisfy wetland hydrology.
The wetland hydrology criterion can be satisfied with observation of one (1) primary hydrology
indicator or two (2) secondary hydrology indicators. Potential primary indicators of wetland
hydrology may include, but are not limited to: inundation, saturation, water marks, drift lines,
sediment deposits, and a thin muck surface. Potential secondary indicators of wetland hydrology
may include, but are not limited to: surface soil cracks, drainage patters, saturation visible on aerial
imagery, and the FAC-neutral test.
OFF-SITE METHODOLOGY
Map Review
Prior to fieldwork, several mapping sources were consulted to identify potential wetland habitats.
The sources consulted include the United States Fish and Wildlife Service (USFWS) National Wetland
Inventory (NWI), United States Department of Agriculture (USDA) Natural Resources Conservation
3670 Togo Road, Orono, MN Page 3
Service (NRCS), formerly Soil Conservation Service (SCS) Soil Survey, Minnesota Department of
Natural Resources (DNR) Public Waters Inventory (PWI), and United States Geological Survey
(USGS) Topographic maps. Areas indicating evidence of potential wetland conditions were
evaluated in greater detail through fieldwork.
Precipitation Data Analysis
Precipitation data from the Minnesota Climatology Working Group and Natural Resources
Conservation Service WETS Tables were used in conjunction with the NRCS Method for Evaluating
Antecedent Moisture Conditions to determine precipitation conditions under which the investigation
was conducted.
ON-SITE METHODOLOGY
Field Sampling Procedures
Sample transects were established in representative transition zones between wetland and upland
for each observed plant community. For potential wetland areas greater than five acres in size, a
minimum of three transects were established along the baseline wetland boundary for lengths of up
to one mile, three to five transects for one to two miles, five to eight transects for two to four miles,
and eight or more transects for wetland baseline boundaries that exceed four miles in length.
Transect intervals do not exceed 0.5 mile apart for each other.
Transects are comprised of two sample points, one sample in upland and one sample point in
wetland. A field data sheet was completed describing the dominant soil characteristics (to a
minimum of 24 inches below the soil surface), plant communities, and hydrology indicators at the
sample point. The presence of water was observed after time (depending on soil characteristics)
was allowed for movement of water through the soil substrate. Absolute percent areal cover was
recorded for the species that were observed (which may exceed 100% total area due to overlap)
and dominance was determined by using the 50/20 rule. Vegetation was sampled within each
stratum present at a sample point using the following circular plot sizes:
• Trees - 30 ft radius
• Saplings and Shrubs - 15 ft radius
• Herbaceous - 5 ft radius
• Woody Vines - 30 ft radius
The sample points were marked with 4-foot lathe, photographed, and flagged with surveyor's tape
(if not within an agricultural land use). Other samples were taken at unmarked locations to provide
verification of the wetland edge, as needed.
3670 Togo Road, Orono, MN Page 4
Wetland Boundary Delineation
The wetland boundaries were determined using changes in topography, dominance of
hydrophytic/non-hydrophytic vegetation, hydric soil indicators, and/or hydrology characteristics.
Wetland edges were marked with pink"wetland delineation"flags. The wetland edge is considered
to be the highest extent of the wetland basin. Areas below the flagged edge satisfy the three
required wetland criteria while areas above were lacking in one or more of these criteria.
US Army Corps of Engineers Regulatory Guidance Letter 90-6 requires documentation sufficient to
allow a reasonably accurate replication of the delineation at a future date. Reasonably accurate is
defined as within 0-2 meters accuracy. Precise positions of sample points and the wetland edge
have been located by a sub-meter GPS unit and have been included in the wetland delineation
drawing or map for this property.
Wetland Type Classification
Wetlands were classified using Wetland Plants and Plant Communities of Minnesota and Wisconsin
(Eggers & Reed 2007), Classification of Wetlands and Deepwater Habitats of the United States
(Cowardin, et al, 1979) and Wetlands of the United States (Fish and Wildlife Service Circular 39,
Shaw and Fredine 1971).
Findings
MAP REVIEW
The NWI map lists one NWI signature in the northern half of the investigation area. The basin is listed
as a Freshwater Emergent Shallow Marsh Wetland (PEM1C). The basin complex is shown in Figure 2,
Appendix A.
Soils within the investigation boundary have been mapped by the NRCS along with their hydric
classification. The location of each soil unit occurring within the investigation boundary is shown on the
Hennepin County Soil Survey map (Figure 3, Appendix A).
There is one DNR Public Water that just barley crosses into the investigation area to the north. The
basin is listed as an Unnamed (27091500) Public Water Wetland (Figure 2, Appendix A).
The LiDAR map (Figure 4, Appendix B) illustrates the highest elevation at the southwest area of the site
and the lowest elevation at the northeast area of the site. Elevations vary slightly within the project
boundary, ranging from 932 feet above msl to 936 feet above msl.
3670 Togo Road, Orono, MN Page 5
ANTECEDENT PRECIPITATION DATA ANALYSIS
The precipitation received in the project area during the previous three months was within the normal
range (30-70th percentile) for this area. Prior to the sample date of June 21, 2016, there was dry
precipitation in May, above normal precipitation in April and normal precipitation in March. Therefore
the field work was completed under normal conditions according to the precipitation worksheet for
wetland delineations (Appendix Q.
FIELD DELINEATION RESULT
Based on the data reviewed and fieldwork conducted, one (1) area was examined for wetland
characteristics within the project area. One (1) wetland was ultimately delineated and is further
described within this report. The delineated wetland is identified as Wetland A, which includes sample
points SP 1-A Up and SP 2-A Wet.
Field data forms for each sample point are located in Appendix B. Refer to Figure 6 (Appendix B) for a
map of the project boundary, wetland basins, sampling transects, and area. Photos of the wetland basin
within the project boundary are included in Appendix C.
OTHER AQUATIC RESOURCES
There is one additional prominent aquatic resources adjacent to the project boundaries. There is a NWI
basin located to the northeast of the project boundary, listed as a Deep Marsh Freshwater Pond (PABG)
(Figure 2, Appendix A). Other prominent aquatic resources nearby are Lake Minnetonka, to the south
and its associated bays, Crystal Bay to the east and West Arm to the south.

Wetland A
Wetland A was located on the edge of a Type 3 Shallow Marsh located along the northern boundary
of the subject property. The wetland extended beyond the subject property to the north, east, and
west. Wetland A had a distinct boundary in vegetation change from a manicured lawn into natural
hydrophytic vegetation at the edge of the wetland. Wetland A was flagged primarily based off of a
change from upland vegetation to hydrophytic vegetation. The upland area had minimal slope into
the wetland, but dropped in elevation at the edge of Wetland A. Sample points SP 1 and SP 2 were
taken to delineate the wetland and can be viewed in Appendix B.
3670 Togo Road, Orono, MN Page 7
Recommendations
Activities impacting or potentially impacting the wetlands identified are regulated through several levels
of government in Minnesota:
• Federal: US Army Corps of Engineers: Permit Programs under Section 404 of the Clean Water
Act and Section 10 of the Rivers and Harbors Act
• Federal: USDA NRCS: Wetland Conservation Provisions of the 1996 Farm Bill
• State Of Minnesota: Minnesota Department of Natural Resources: Public Waters Work Permit
Program
• Local: Local Units of Government (LGU) administer the Minnesota Wetland Conservation Act
(WCA) of 1991.
Please note that grading, excavating, or filling is not allowed until all necessary permits have been
obtained. If wetland impacts are proposed, ISG can assist in the proper steps to acquire the appropriate
permit or exemption. By initiating the permit process as soon as possible, potential costly delays to the
project may be avoided.

PART FOUR: Aquatic Resource Impact' Summary
If your proposed project involves a direct or indirect impact to an aquatic resource (wetland, lake, tributary, etc.) identify each
impact in the table below.Include all anticipated impacts,including those expected to be temporary.Attach an overhead view map,
aerial photo, and/or drawing showing all of the aquatic resources in the project area and the location(s)of the proposed impacts.
Label each aquatic resource on the map with a reference number or letter and identify the impacts in the following table.
Aquatic Type of Impact Duration of County,Major
Existing Plant
Aquatic Resource (fill,excavate, Impact Overall Size of Watershed
(wetland,lake, es #,
ID(as noted on Resource Type drain,or Permanent(P) Size of Impact2 Aquatic Community and Bank
tributary etc.) Impact Area

vegetation) (T)1 P of Impact Areas
'If impacts are temporary;enter the duration of the impacts in days next to the"T". For example,a project with a temporary access fill that
would be removed after 220 days would be entered"T(220)".
21mpacts less than 0.01 acre should be reported in square feet. Impacts 0.01 acre or greater should be reported as acres and rounded to the
nearest 0.01 acre. Tributaryimpacts must be reported in linear feet of impact and an area of impact by indicating first the linear feet of impact
along the flowline of the stream followed by the area impact in parentheses). For example,a project that impacts 50 feet of a stream that is 6
feet wide would be reported as 50 It(300 square feet).
'This is generally only applicable if you are applying for a de minimis exemption under MN Rules 8420.0420 Subp.8,otherwise enter"N/A".
'Use Wetland Plants and Plant Community Types of Minnesota and Wisconsin 3'd Ed.as modified in MN Rules 8420.0405 Subp.2.
$Refer to Major Watershed and Bank Service Area maps in MN Rules 8420.0522 Subp.7.
If any of the above identified impacts have already occurred,identify which impacts they are and the circumstances associated
with each:
No impacts are proposed.

Attachment A
Request for Delineation Review, Wetland Type Determination, or
Jurisdictional Determination
By submission of the enclosed wetland delineation report,I am requesting that the U.S.Army Corps of Engineers,St.Paul District
(Corps)and/or the Wetland Conservation Act Local Government Unit(LGU)provide me with the following(check all that apply):
®Wetland Type Confirmation
®.Delineation Concurrence. Concurrence with a delineation is a written notification from the Corps and a decision from the LGU
concurring,not concurring,or commenting on the boundaries of the aquatic resources delineated on the property.Delineation
concurrences are generally valid for five years unless site conditions change.Under this request alone,the Corps will not address
the jurisdictional status of the aquatic resources an the property,only the boundaries of the resources within the review area
(including wetlands,tributaries,lakes,etc.).
❑Preliminary Jurisdictional Determination.A preliminary jurisdictional determination (PJD)is a non-binding written indication
from the Corps that waters,including wetlands,identified on a parcel may be waters of the United States.For purposes of
computation of impacts and compensatory mitigation requirements,a permit decision made on the basis of a PJD will treat all
waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be
appealed.
❑Approved Jurisdictional Determination.An approved jurisdictional determination(AJD) is an official Corps determination that
jurisdictional waters of the United States are either present or absent on the property.AJDs can generally be relied upon by the
affected party for five years.An AJD may be appealed through the Corps administrative appeal process.
In order for the Corps and LGU to process your request,the wetland delineation must be prepared in accordance with the 1987
Corps of Engineers Wetland Delineation Manual,any approved Regional Supplements to the 1987 Manual,and the Guidelines for
Submitting Wetland Delineations in Minnesota(2013).
