"This Regional Supplement is part of a nationwide effort to address regional <br /> wetland characteristics and improve the accuracy and efficiency of wetland- <br /> delineation procedures. Regional differences in climate,geology,soils,hydrology <br /> plant and animal communities,and other factors are important to the identification <br /> and functioning of wetlands.These differences cannot be considered adequately in a <br /> single national manual. The development of this supplement follows National <br /> Academy of Sciences recommendations to increase the regional sensitivity of <br /> wetland-delineation methods(National Research Council 1995).The intent of this <br /> supplement is to bring the Corps Manual up to date with current knowledge and <br /> practice in the region and not to change wetland boundaries." "...This Regional <br /> Supplement is designed for use with the current version of the Corps Manual <br /> (Environmental Laboratory 1987)and all subsequent versions.Where differences in <br /> the two documents occur, this Regional Supplement takes precedence over the <br /> Corps Manual for applications in the Midwest Region." <br /> National Wetland Inventory (NWI) maps (Figure 2), Web Soil Survey of Orono and Hennepin <br /> County maps(Figure 3),Minnesota Protected Waters maps(Figure 4),and LMIC aerial photographs <br /> obtained online were reviewed prior to the site visit to identify areas that may be wetlands. Areas <br /> illustrating evidence of wetland conditions were examined in greater detail during the field survey. <br /> Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and used to <br /> characterize wetland types and determine wetland boundaries. Sample transects were established in <br /> representative wetland-to-upland transition zones in order to characterize the vegetation,soils,and <br /> hydrology of the site. The transects consisted of a representative upland sample point and <br /> representative wetland sample point at each delineated wetland basin. Information obtained from the <br /> sample points can be found on the field data sheets located in the Technical Documentation Section. <br /> Wetland boundaries were marked at the site by pink"Wetland Delineation"pin flags.The wetland <br /> boundary is considered to be the topographically highest extent of the wetland basin; areas below <br /> the staked boundary met the three required wetland criteria while areas above were lacking in one or <br /> more of these criteria. Wetland classification followed methods described by Cowardin et al.(1979) <br /> and used in the NWI(e.g. PEMB, PSS IC,etc.),completed by the U.S. Fish and Wildlife Service. <br /> The Circular 39 and Eggers and Reed classification systems are also given. The indicator status of <br /> plants,as described in The Technical Documentation Section, was determined using the National <br /> List of Plant Species That Occur in Wetlands—Region 3 (Sabine 1999). <br /> RESULTS <br /> Background Information-(Office-Based Investigation) <br /> The NWI map(Excelsior Quadrangle)illustrates no National Wetland Inventory wetlands present on <br /> the property(Figure 2). <br /> The Web Soil Survey of Orono and Hennepin County, Figure 3, classifies three soil map units <br /> present on the subject property(See Figure 3).The map units that are classified as"non-hydric"soils <br /> are the Angus loam and the Lester loam.The Hamel loam classification is the only"hydric"soil map <br /> Svoboda Ecological Resources 840 Old Crystal Bay Rd. <br /> Project No.:2010-027-03 2 Jeff Martineau/Coldwell Banker-Burnet <br /> 1 <br />
