• The 360 North Arm Lane site was inspected on August 24, 2012 for the presence and

within site boundaries.
• The DNR Protected Waters Map showed DNR Protected Water 133P (north Arm of Lake

Wetland Delineation Report
I. INTRODUCTION
The 360 North Arm Lane site was examined on August 24, 2012 for the presence and extent of
wetland. The 3.9-acre site was located in Section 6, Township 117N, Range 23W, City of
Orono, Hennepin County, Minnesota(Figure 1).
The site consisted of a single-family home surrounded by mowed lawn and landscape plantings,
and two wetlands (Figure 2). Topography on the site sloped downhill from west to
east/southeast,towards Lake Minnetonka.
II. METHODS
Wetlands were identified using Routine Determination methodology described in the Corps of
Engineers Wetlands Delineation Manual(Waterways Experiment Station, 1987)and Regional
Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest as required by
Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act.
Wetland boundaries were identified as the upper-most extent of wetlands, which met criteria for
hydric soils,hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were
marked with pink pin flags and located by Gronberg Associates.
Soils,vegetation, and hydrology were documented at representative locations along the wetland-
upland boundary. Plant species dominance was estimated based on the percent aerial or basal
coverage visually estimated within a 30-foot radius for trees and vines, 15-foot radius for the
shrub layer, and a 5-foot radius for the herbaceous layer within the community type being
sampled.
Soils were characterized to a minimum depth of 18-20 inches(unless otherwise noted)utilizing
Munsell Soil Color Charts and standard soil texturing methodology. Hydric soil indicators used
in reporting are from the NTCHS Field Indicators of Hydric Soils in the United States (USDA
Natural Resources Conservation Service Version 7, 2010)which are commonly found in the
Midwest.
Plants were identified using standard regional plant keys. Taxonomy was based on the Manual
of Vascular Plants of Northeastern United States and Adjacent Canada, Ed. 2 (New York
Botanical Garden, 1991). Indicator status of plant species was taken from the 2012 National
Wetland Plant List (Lichvar, R.W. and Kartesz, J.T. 2009.North American Digital Flora:
2
National Wetland Plant List, version 2.4.0 (https://wetland�lants.usace.army.mil). U.S. Army
Corps of Engineers,Engineer Research and Development Center, Cold Regions Research and
Engineering Laboratory, Hanover,NH, and BONAP, Chapel Hill,NC.)
III. RESULTS
Review of Soils. NWI,and DNR Information
The National Wetland Inventory Map (NWI) (U.S. Fish& Wildlife Service) shows one
PEMC/PEMF wetland within site boundaries (Figure 3).
The Soil Survey of Hennepin County,Minnesota
(http://soils.usda.gov/survey/geography/ssurgo/) showed the following soil types with or near
site boundaries (Figure 4). Hydric soils are indicative of wetland conditions when undrained.
Partially hydric soil may contain hydric soil inclusions.
SMU Map unit name Rating
L16A Muskego, Blue Earth, and Houghton soils,ponded, 0 to 1 percent All Hydric
slo es
L22C2 Lester loam, morainic, 6 to 12 percent slopes, eroded Partially Hydric
L24A Glencoe loam, depressional, 0 to 1 percent slopes All Hydric
L35A Lerdal loam, 1 to 3 percent slopes Partially Hydric
L36A Hamel, overwash-Hamel complex, 1 to 4 percent slopes Partially Hydric
L40B Angus-Kilkenny complex, 2 to 6 percent slopes Partially Hydric
L41 C2 Lester-Kilkenny complex, 6 to 12 percent slopes, eroded Partially Hydric
L41 E Lester-Kilkenny complex, 18 to 25 percent slopes Partially Hydric
The DNR Protected Waters Map,Hennepin County (http://deli.dnr.state.mn.us� showed DNR
Protected Water 133P (Lake Minnetonka)within site boundaries (Figure 5). According the
DNR Lake Finder web page, Lake Minnetonka has and Ordinary High Water Level (OHW)of
924.4 ft msl.
Wetland Determinations and Delineations
Potential wetlands were evaluated in greater detail during field observations on August 24, 2012.
Two wetlands were identified and delineated on the subject site(Figure 2). Corresponding data
forms are included in Appendix A. The following description of the wetlands and adjacent
upland reflects conditions observed at the time of the field visit. At that time, herbaceous
vegetation was growing and temperatures were typical of summer. Wetland hydrology was
assumed to be typical of the season based on normal range precipitation amounts in the
preceding 30 days (Appendix B). The survey of wetland boundaries is presented in Appendix
C.
Wetland 1 was a Type 2/6 (PEM 1 B/SS 1 B)fresh(wet)meadow and scrub-shrub wetland
complex. The wetland was dominated by reed canary grass with lesser amounts of purple
3
loosestrife,jewelweed, smartweed, giant goldenrod and willow shrubs. Soils observed below the
wetland boundary were black mixed clay/loam/gravel fill with redoximorphic features to 24
inches meeting the F6 indicator for hydric soil (redox dark surface). No free water or saturation
was observed within 24 inches of the soil surface in the sample borehole. Secondary indicators
of wetland hydrology included geomorphic position and the FAC-Neutral Test.
Adjacent upland at the sample location was mowed lawn dominated by Kentucky bluegrass with
lesser amounts of dandelion, common plantain, and creeping Charlie. Soils were mixed brown
and black fill lacking in redoximorphic features. No primary or secondary indicators of wetland
hydrology were observed.
The delineated boundary followed an abrupt change in vegetation composition and a gradual
change in topography. Wetland 1 corresponded to an NWI-mapped wetland and was located
within an areas mapped with partially hydric soil on the soil survey. A one-foot diameter tile
was located within the east wetland boundary, and discharged into Lake Minnetonka. The
elevation change where the wetland met the shoreland of Lake Minnetonka was approximately 3
feet drop. The outlet was dry at the time of the delineation.
Wetland 2 was a Type 2/6 (PEM 1 B/SS 1 B/EM 1 C)fresh(wet)meadow, scrub-shrub wetland
complex. The wetland fringe at the sample location was dominated reed canary grass, crack
willow, and black willow. Soils observed just below the wetland boundary were black silty clay
loam with redox concentrations to 18 inches, meeting the F6 indicator for hydric soil, underlain
by peat to a depth greater than 24 inches. No free water or saturated soils were observed within
24 inches of the soil surface in the sample borehole, but 2 secondary indicators (geomorphic
position and the FAC-Neutral Test)were observed.
Adjacent upland at the sample location was mowed lawn dominated by Kentucky bluegrass with
lesser amounts of creeping Charlie. Soils were mixed brown and black fill to 30 inches over
black peat to 36 inches. No primary or secondary hydrology indicators were observed.
The delineated boundary followed an abrupt change in vegetation composition and a gradual
change in topography. Wetland 2 corresponded to an NWI-mapped wetland and was located
within an area mapped with partially hydric soils on the soil survey. The wetland continued east
to the shore of Lake Minnetonka. The elevation change where the wetland met the shoreland of
Lake Minnetonka was approximately 3 feet drop.
Other Areas
No other areas with wetland vegetation or hydrology were observed on the site. No other areas
were shown as wetland on the NWI map or shown as hydric soils on the survey.

V. CERTIFICATION OF DELINEATION
The procedures utilized in the described delineation are based on the COE 1987 Wetland
Delineation Manual as required by Section 404 of the Clean Water Act and the Minnesota
Wetland Conservation Act. Both the delineation and report were conducted in compliance with
regulatory standards in place at the time the work was completed.
All site boundaries indicated on figures within this report are approximate and do not constitute
an official survey product.
