INTRODUCTION The subject parcel is appro�imate(y �.54 acres and is dominated by turf grass and hardwood trees. The topography of the site declines east to west and south towards the wetland area at varying degrees and undulates within the wetland area. The sunounding land use consists mostly of single- family homes. The identified wetland was classified according to the Cowardin et al. and the Circular 39 classification systems and marked with pink "Wetland Delineation" pin flags. Please find within the Technical Documentation Section; field data sheets, plant indicator status information, soil survey information, and wetland definition information. METHODS The methods used to delineate the subject parcel are as described in the 1987 US Army Corps of Engineers Wetlands Delineation Manual and the 2007 Midwest Region Supplement Manual. In the 1987 Manual, the methods used were described under the "routine" methods for areas less than 5 acres. This methodology is followed in order to assess whether the three parameters of a wetland are met for areas on the subject parcel. The three parameters reauired under normal circumstances in order to delineate a wetland are described in the Technical Documentation Section. The Midwest Regional Supplement Wetland Delineation Manual is also being utilized to increase the accuracy of our wetland boundaries. This addendum to the original 87 Manual was created to address the many regional differences that affect wetlands and the delineation methods used throughout the country. The following eYplanations are passages from that document. "This Re�ional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland- delineation procedures. Regional differences in climate,geology,soils,hydrology p(ant and animal communities,and other factors are important to the identification and functioning of wetlands.These differences cannot be considered adequately in a single national manuaL The development of this supp(ement follo�vs National Academy of Sciences recommendations to increase the regional sensitivity of wetland-de(ineation methods(National Research Council 1995).The intent of this supplement is to bring the Corps Manual up to date with current knowledge and practice in the region and not to change wetland boundaries." "...T'his Regional Supplement is desi;ned for use with the current version of the Corps Manual (Environmental Laboratory 1987)and all subsequent versions.Where differences in the two documents occur, this Regional Supplement takes precedence over the Corps Manual for applications in the Midwest Region." National Wetland Inventory(NWI) maps(Figure 2),Soil Szrrvey of Hennepin Cotrnty maps(Figure 3),Minnesota Protected Waters maps(Figure 4),and 2006 aerial photographs were reviewed prior to the site visit to identify areas that may be wetlands. Areas illustrating evidence of wetland conditions were examined in greater detail during the field survey. Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and used to characterize wetland types and determine wetland boundaries. A sample transect was established in a representative wetland-to-upland Svoboda Ecological Resources 192� Fox St. Project No.:2010-025-03 2 Joanne Watson
