<br />2.2.2 Soil Survey
<br />
<br />The Natural Resources Conservation Service (NRCS) Web Soil Survey map, which is
<br />included as Figure 3, was reviewed for information pertaining to the Site soils. The Soil
<br />Survey indicated the Site soil units consist of Muskego, Blue Earth, and Houghton soils,
<br />ponded, 0 to 1 percent slopes (L16A), Lester loam, 6 to 16 percent slopes, moderately
<br />eroded (L22C2, L22D2), Lester loam, 10 to 22 percent slopes (L22E), Hamel, overwash-
<br />Hamel complex, 0 to 3 percent slopes (L36A), Angus loam, 2 to 6 percent slopes (L37B),
<br />Angus-Kilkenny complex, 2 to 6 percent slopes (L40B), Lester-Kilkenny complex, 6 to 10
<br />percent slopes, moderately eroded (L41C2), Lester-Kilkenny complex, 16 to 22 percent
<br />slopes, (L41E), Muskego and Houghton soils, 0 to 1 percent slopes (L50A), and
<br />Udorthents, wet substratum, 0 to 2 percent slopes (U2A). Of the identified soil types,
<br />Muskego, Blue Earth, and Houghton, Klossner, and Muskego and Houghton soils are
<br />considered hydric soils.
<br />
<br />2.2.3 Wetland Inventory Maps
<br />
<br />The United States Fish and Wildlife Service (USFWS)-National Wetland Inventory (NWI)
<br />map for the Site area, which is included as Figure 4, depicts three freshwater emergent,
<br />persistent, temporarily or seasonally flooded wetlands (PEM1A, PEM1C) in the in the
<br />northern property, and one freshwater emergent persistent, seasonally flooded (PEM1C)
<br />wetland in the southern portion of the eastern property. A lacustrine, littoral,
<br />unconsolidated bottom, permanently flooded (L2UBH) wetland is located adjacent the
<br />southern area. NWI maps generally show the approximate location of wetlands as of the
<br />time of publication.
<br />
<br />2.2.4 Public Waters Inventory
<br />
<br />The Minnesota Department of Natural Resources (DNR) Public Waters Inventory (PWI)
<br />produces a map of the protected wetlands and waters of the State. The PWI map, which
<br />is included as Figure 5, identified two Public Waters. One is located in the northeastern
<br />portion of the northern area with the identification number: 27086600. The other Public
<br />Water (Lake Minnetonka) is located adjacent the southern area with an identification
<br />number of 27013302. Additional PWI-mapped Public Water are present to the southwest
<br />of the Site.
<br />
<br />
<br />3.0 WETLAND DETERMINATION
<br />
<br />3.1 Methodology
<br />
<br />The wetland determination was made utilizing the techniques of the Routine Onsite
<br />Method, as described in the 1987 U. S. Army Corps of Engineers Wetland Delineation
<br />Manual, updated February 25, 1997 and utilizing the Midwest Regional Supplement.
<br />Determination of hydric soils, site hydrology, and hydrophytic vegetation were made
<br />according to the procedures and guidelines described in the manual. Sampling locations
<br />were selected to be representative of wetland/upland transition areas.
