Wetland Delineation Report
5416 Stagecoach Trail North
Oak Park Heights, Minnesota
September 12, 2022
Background
Bopray Environmental Services LLC (BES) has completed a wetland delineation on the 1.4-acre
lot located at 5416 Stagecoach Trail North in Oak Park Heights. The site is in the NE 1/4, NE 1/4,
SW'/4, Section 3, T29N, R2OW, and Washington County, Minnesota (Figure 1). The site
consists of a gently sloping park like mix of mature trees and lawn. The topography of the site is
sloping down to the northwest according to the U.S.G.S. quadrangle topographic map (Figure
2). The approximate site and sample locations are shown on an aerial photo in Figure 3. The
field wetland determination was done on September 8, 2022. The purpose of this delineation
was to identify potential wetlands on the site for development and for regulatory purposes.
Methodologies Precipitation % Normal

The site was evaluated for wetlands based on
the methods contained in the "Level 2 Routine — �,�

antecedent precipitation for the proceeding three months for this site was Normal at the time of
the site visit (Appendix A).
Results
Resource Maps Review
The National Wetlands Inventory (NWI) (Figure 4) does not identify any wetlands on the site.
The DNR Protected Waters Inventory map (Figure 5) does not identify any public waters
wetlands on the site. The Washington County Soils Survey (Figure 6) shows the site is
mapped as the Chetek sandy loam (155B, 155C) and Pits & Gravel (1029) soil map units.
These soil map units are listed as having 0% hydric soils inclusions.
Sample Point 1
Sample Point 1 (SP-1) was established in the lowest point of the site, near the northwest
property corner (Figures 7 and 8). The vegetation at SP-1 is dominated by red elm (Ulmus
rubra), cottonwood (Populus deltoides), river birch (Betula nigra), sumac (Rhus typhina), green
ash (Fraxinus pennsylvanica), black walnut (Juglans nigra), creeping Charlie (Glenchoma
hederacea), Virginia creeper(Parthenocissus quinquefolia), and brome grass (Bromus inermis).
The vegetation community did not meet the dominance test and had a prevalence index of 3.56.
The soils consisted of six inches of 10YR 2/2 loamy fine sand, over eight inches of 10YR 3/2
loamy fine sand, over seven inches of 10YR 3/2 loamy fine sand, over four inches of 10YR 3/3
loamy fine sand, over 10YR 3/4 loamy fine sand. There were no redox features in the soil
profile and the subsoil had a soil matrix chroma too bright (Value > 2) to meet the hydric soils
criteria. The water table and saturated soil were not observed within a depth of 31 inches in the
SP-1 soil pit at the time of the site visit. There were no other wetland hydrology indicators
observed at the SP-1 sample point. The area failed to meet all three wetland criteria.
Adjacent Stormwater Pond
Off-site to the west there is a dry stormwater pond more than 50 feet west of the west property
boundary (Figure 9). The basin was approximately 10 feet lower than the elevation of the
northwest property corner. A stormwater outlet culvert was observed at the south end of the
pond and presumed to be from the transportation facility to the south of the site.

Wetland Classification
BES' classification of the wetlands is based on observations of the site and is include in Table 1
below.
Table 2. Summary of Wetland Characteristics
Wetland Class Circ. 39 Isolated Comments
Type Y/N
SP-1 Non-wetland N/A N/A The lowest point on the site fails to
meet all three of the mandatory
wetland criteria.
Jurisdiction
Table 2 indicates whether the wetlands are isolated or not for purposes of U.S. Army Corps of
Engineers (COE)jurisdiction under Section 404 of the Clean Water Act. This determination is
made by BES in the field at the time of the delineation and is essentially our best professional
opinion based on the portion of the particular wetland we observed. In some cases, only a
small portion of the wetland edge that is present on the property being delineated is evaluated.
If no inlets or outlets are observed in the evaluated area, and none are evident on topographic
maps or aerial photos, we are inclined to determine the wetland is isolated. However, since the
entire wetland is sometimes not assessed, it is possible that inlets and/or outlets do exist and
that the wetland has a surface connection to a federal "navigable" water and, thus, falls within
the jurisdiction of Section 404. Therefore, a determination by BES of whether a particular
wetland is isolated or not should not be considered a final determination with regard to COE
jurisdiction until the COE concurs with the determination. There are no wetlands on the site, so
the COE will not require a permit for development of the site.
The site is not identified as on Minnesota protected waters inventory. The DNR will not have
jurisdiction over this site. In general, wetlands in this area are regulated under the Minnesota
Wetland Conservation Act (WCA) which is administered by the City of Oak Park Heights as the
Local Government Unit (LGU).
A copy of this report should be submitted to the LGU responsible for administering the WCA.
Supplying this reports will serve the beginning the process of obtaining concurrence with the no
wetland determination.
