WETLAND DETERMINATION REPORT <br /> Windsor Blue Housing Plat Wetland Delineation <br /> METHODS <br /> May 6,2014 <br /> 2.0 METHODS <br /> 2.1 WETLANDS <br /> Wetland determinations were based on the criteria and methods outlined in the U.S.Army Corps of <br /> Engineers Wetlands Delineation Manual,Technical Report Y-87-1(1987)and subsequent guidance <br /> documents(USACE 1991,1992),and the applicable Regional Supplement to the Corps of Engineers <br /> Wetland Delineation Manual. <br /> The wetland determination involved the use of available resources to assist in the assessment such as U.S. <br /> Geological Survey(USGS)topographic maps,U.S.Department of Agriculture Natural Resources <br /> Conservation Service(NRCS)soil survey,WDNR Wisconsin Wetland Inventory(WWI)mapping,and <br /> aerial photography. <br /> On-site wetland determinations were made using the three criteria(vegetation,soil,and hydrology)and <br /> technical approach defined in the USACE 1987 Manual and applicable Regional Supplement.According to <br /> procedures described in the 1987 Manual and applicable Regional Supplement,areas that under normal <br /> circumstances reflect a predominance of hydrophytic vegetation,hydric soils,and wetland hydrology(e.g., <br /> inundated or saturated soils)are considered wetlands. <br /> Additionally,as climate plays an important role in the formation and identification of wetlands,the <br /> antecedent precipitation in the months leading up to the field investigation was reviewed. The current <br /> year's precipitation data was compared to long-term(3o-year)precipitation averages and standard <br /> deviation to determine if precipitation was normal,wet,or dry for the area using a WETS analysis as <br /> developed by the NRCS. <br /> Sampling points were identified and surveyed with a Global Positioning System(GPS)capable of sub- <br /> meter accuracy and mapped using Geographical Information System(GIS)software. <br /> Stantec <br /> 2.3 <br />
