INTRODUCTION
Midwest Natural Resources, Inc. (MNR) was contracted by Timberline Homes to provide level one wetland
delineation services for the 2.5-acre property located at 6651 Galpin Blvd. in Chanhassen, Minnesota
(Appendix A, Figure 1). MNR conducted a level one wetland delineation of the site to determine if any wetland
areas are present within the property. It was determined from desktop review and confirmed in the field that
one wetland is present within the northeastern part of the property along with a linear waterbody channel that
flows out of the on-site wetland.
DESKTOP REVIEW
As part of the level one delineation review, MNR staff conducted a desktop review to evaluate the following
data within the project area. Background data are illustrated in the figures in Appendix A.
• Minnesota’s Public Waters Inventory (PWI)
• National Wetlands Inventory (NWI)
• National Hydrography Dataset (NHD)
• County Soil Surveys
• Aerial Imagery
• Hillshade LiDAR
Review of the PWI (Figure 2, Appendix A) indicates no Public Waters within the site and the NWI (Figure 3,
Appendix A) indicates one wetland community (PEM1C) within the subject property. According to the Carver
County soil survey, Hamel loam make up the hydric soil units within the site with the remainder being all non-
hydric soils (Figure 4, Appendix A). Below is Table 1 that lists all of the soils mapped within the subject
property and includes their map unit symbol, map unit name, drainage class, and whether it is a hydric soil or
not. No precipitation data was reviewed for this level 1 wetland delineation review.

HM Hamel loam, 0 to 2 percent slopes poorly drained hydric

KD2 Lester-Kilkenny complex, 10 to 16 percent slopes,

KE2 Lester-Kilkenny complex, 16 to 22 percent slopes well drained non-hydric
METHODS
In addition to reviewing all relevant wetland GIS data, the subject property was evaluated via a pedestrian
survey on March 2, 2026 to determine and document the presence of wetlands. All potential wetland areas
were evaluated utilizing the Routine “Onsite” Determination Method contained in the Regional Supplement to
the Corps of Engineers Wetland Delineation Manual: Midwest Region for the 1987 Wetlands Delineation
Manual Technical Report Y-87-1. For each potential wetland within the survey area, the three wetland
parameters except soils (vegetation and hydrology) were examined to determine wetland status. Due to the
time of the year, no sample transects were taken along the wetland/upland transition of the wetland that was
reviewed in the field.

RESULTS AND DISCUSSION
The subject property was surveyed for the presence of wetland and field surveys resulted in one wetland and
one linear waterbody channel being present within the property (Figure 5, Appendix A). The property itself
consists of a single-family home with a deciduous woodland dominated by box elder trees, areas of maintained
turfgrass behind and to the south of the house, part of one wetland and part of a linear waterbody channel.
Across the site there is approximately 40’ of topography change with the high point occurring along the
western property boundary at an elevation of 1028’ and the lowest point occurring along the eastern property
boundary at an elevation of 984’. No other depressional areas were observed within the property that resemble
wetland.
Wetland Area
Wetland 1
Wetland 1 is located in the northeastern part of the property and extends off-site to both the northwest and
east of the property. This wetland would be considered a sloping/depressional, Type 2/3/5, fresh wet meadow,
shallow marsh and open water wetland complex. The fresh wet meadow/shallow marsh is dominated by
narrowleaf cattail (Typha angustifolia) and reed canary grass (Phalaris arundinacea). Other plants are likely
present within the wetland but were not able to be observed due to snow cover. The open water part of the
wetland appears to have been excavated sometime in the past with spoil piles observed all around this part of
the wetland. A small upland berm is situated between the fresh wet meadow/shallow marsh part and the open
water part of the wetland. Figure 6, Appendix A is a Hillshade LiDAR figure that clearly shows the berm between
wetland areas.

corner of the property
facing NW at the fresh
wet meadow/shallow
marsh part of the
wetland. The wetland
slopes slightly from
west to east with
approximately 2-3’ of
fall.

At the southern end of this wetland is an open water body with an outlet channel that flows through the property
for approximately 50’ or so before it continues off-site to the south and east. At the time of the survey the
channel was frozen over and appears to be approximately 10-15’ wide with gently rising sideslopes on both
sides.

east.

Historic Imagery Review
As part of the level one wetland delineation process, MNR reviewed additional information for determining the
extent of possible wetland within the site. Appendix B includes five years of historic imagery including 1991,
2000, 2012, 2020, and 2023. These years were selected since they have higher resolution than other available
years and interpreting any wetland signature was easier with higher resolution imagery.
Based on review of historic imagery, the wetland boundary digitized appears to match up very closely with the
signature of wetland that can be seen throughout the years.
