Cfluncil 1995).The intent of this supplemcnt is to bring the Corps Manual up to date with current knowledge and practice in the region and not to change we#iand boundaries." "...'This Regional Supplement is designed for uso with the cument vcrsion of the Corps Mauual (Environmental Laboratory 1987} and all subsequent versions. Where differences in the two documents occur, this Reg�ional Supplcmcnt tskes prccedence over thc Corps Manual for applications in the Midwest Region" National Wetland Inventory {NWI) maps (Figure 2a) Hennepin County Wetland Inventory {HCWI} maps (Figure 2b), 2014 DNR NWI Update maps (Figure 2c), Web Soil Survey of Hennepin County map(Figure 3),Minnesota Public Waters Inventory maps (Figure 4), and 2012 aerisl photographs were reviewed prior to the eite viait to identify areas that may be wetlands. Areas illustrating evic3ence of wetland conditions were examine�in greater detail during the field survey. Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and u.sed. to characterize wetland types and determine wetland boundaries. Sample transects were established in representative wetland-to-upland transition zones in order to characterize the vegetation, sails, and hydrology of the site. Transects consist of a representative u}�land sample point and representative wetland sample point. Information abtained at the sample points can be found on the fietd data sheets located in the Technical Documents section. Wetland boundaries were marked at the site by pink "Wetland Delineation" pin flags. The wetland boundary is cansidered to be the tapographically kughest extent of the wetland basiu; areas below the staked boundary met the thre�required wetland criteria whiJe areas above were laclring in one or more of these criteria. Wetlands were classified in accordance with methods descnbed by Cawardin et al. (1979) and used in the NWI (e.g. PEMB, PSS1C, etc.), comgleted by the U.S. F�sh and Wildlife Service. The Circular 39 and Eggers and Reed classification systems are also given. The indicator status of plants, as described in the Technical Documents section, was determined using the National Wetland Plant List (Lichvar, et al. 2014. httn://wetland pla►ets.usac�.armv miU1. RESULTS The National Wetland Inventory indicates the presence of one large wetland complex along the northern and eastern edge of the survey area. The wetland is categorized by the NWI as PFO/EMCd {Figure 2a). The HCWI indicates probable and potential wetlands in the same loca�ion(Figure 2b). The DNR NWI update in 2014 indicates generally similar wetland types but generally does not map the wetlaads on the 200 Stubbs Bay Road pazcel(Figure 2c). The Web Soil Survey of Hennepin County (Figure 3) identifies six soil znap units within the study area. They are Lester loam, Muskego, Blue Earth, and Houghton, pondad, Cordova loam, Hamel-Glencoe, Angus loam, and LeSueur loam. The Muskego, Blue Earth and Houghton eomplex is considered hydric, the Cordova and the Hamei-Glencoe soils are predomin.antly hydric and the Lester loam, Angus loam and LeSueur loam are considered predaminantly non- h�+dric. Soil series deseriptions are provided in the Technic�l Documents section. The �Vlinnesota Department of Natural Resources, State Protected Waters Map (Public Water Inventory)indicates no public waters or wetlands within the study area(Figure 4).
