Project Overview
On May 2nd, 2013 Arrowhead Environmental Consulting (AEC) performed a wetland
delineation at the 3245 Watertown Road property located in Orono, MN.
• One wetland basin was delineated within and adjacent to the parcel bounds;
Wetland 1 is a Seasonally Flooded Basin located along the southwestern property
line.
• Wetland 1 is not indicated on the NWI map.
• Wetland 1 is indicated on the Minnesota Department of Natural Resources Public
Water Inventory Map (PWI) as a creek/stream.
• Wetland 1 is mapped in the Lester non-hydric soil series.
• Wetland 1 is dominated by reed canary grass, stinging nettle and Virginia
waterleaf.
i • The wetland boundary was generally placed along the vegetative transition from
hydrophytic to non-hydrophytic vegetation (which correlated to a rise in
topography) and where the soil was saturated to the surface.

Introduction
On May 2"d, 2013 Arrowhead Environmental Consulting (AEC) performed a wetland
delineation at the 3245 Watertown Road property located in Orono, MN. The legal
1 description of the project location is: A part of the NE 1/a of Section 5, T117N, R23W,
Hennepin County, Orono, Minnesota. The parcel is a total of 0.61 acres (according to the
Hennepin County Website).
Methods
' AEC utilized the 1987 US Army Corps of Engineers Wetlands Delineation Manual and
Midwest Regional Supplement to perform the wetland delineation. A United States
Geological Survey (USGS) Map (Excelsior Quad) (Figure 1), the Minnesota Department
rof Natural Resources (MN DNR) Public Water Inventory (PWI) Map (Figure 2), the
Hennepin County Soil Survey Map (Figure 3), the National Wetland Inventory (NWI)
Map (Figure 4), and the MCWD Wetland Assessment Map (Figure 5) were reviewed
prior to the site visit and used in the delineation process. The delineated wetland
boundaries (GPS located) are indicated on Figure 6 and are overlaid on a 2012 aerial
image. AEC used the routine delineation method.
Wetland classification followed methods described by the USACOE - St. Paul District;
' Eggers and Reed "Wetland Plants and Plant Communities of MN and WI". The Circular
39 and Cowardin et al. classifications are given as well. The indicator status of plants
was determined using the State of Minnesota — 2012 National Wetlands Plant List Final
Ratings provided by the U.S. Army Corps of Engineers, Cold Regions Research and
Engineering Laboratory.
Pink pinflags were used to delineate the wetlands and were numbered sequentially;
flagging was hung from adjacent vegetation to aid in location of the pinflags. Sample
points were taken to document the vegetation, soils, and hydrology indicators within
' representative upland and wetland locations.
Results
Office Results
Wetland 1 is not indicated on the NWI map. Wetland 1 is mapped in the Lester soil
' series; the Lester soil series is classified as a non-hydric soil (SCS Hydric Soils of the
United States). Wetland 1 is indicated on the Minnesota Department of Natural
Resources Public Water Inventory Map (PWI) as a creek/stream. Wetland 1 is indicated
1 on the MCWD Wetland Assessment Map; however, it is not assigned a management
classification.
' Field Results
Wetland 1
AEC classified Wetland 1 as a Seasonally Flooded Basin (Type 1, PEMA) wetland.
' Wetland 1 is dominated by reed canary grass (Phalaris arundinacea), stinging nettle
(Urtica dioica), and Virginia waterleaf (Hydrophyllum virginianum). The adjacent
r1
upland area is dominated by sugar maple (Acer saccharum), green ash (Fraxinus
pennsylvanica), common buckthorn (Rhamnus cathartica) and common dandelion
(Taraxacum officinals).
The boundary for Wetland 1 exhibited rather steep slopes (a sharp transition in
' topography); in general there was a defined transition between the reed canary grass
(wetland) and the maple, buckthorn, and dandelion (upland). The wetland soil boring
met the F3 (Depleted Matrix) hydric soil indicator with High Water Table, Saturation to
' the Surface, Geomorphic Position, Crayfish Burrows, Oxidized Rhizospheres, and FAC —
Neutral Test hydrology indicators present. The upland soil boring did not meet a hydric
soil indicator and was lacking hydrology indicators. In general, the wetland boundary
was placed where the soil was saturated to the surface. Much of Wetland 1 is floodplain
wetland adjacent to the creek.
Discussion
One wetland basin was delineated within the parcel bounds. Areas delineated as wetland
met the three criteria required for a wetland delineation; dominance of hydrophytic
vegetation, presence of hydric soil, and (at a minimum) one primary hydrology indicator
or two secondary hydrology indicators under normal conditions.
' In order to be official the wetland delineation must be reviewed and approved by the
Local Government Unit (LGU) and potentially other agencies (Local, State, Federal).
1 Any work within or adjacent to a wetland will require Wetland Conservation Act (WCA)
permits (and potentially other permits). Please consult with AEC if you plan on filling,
draining, excavating wetlands within your project location.
