WETLAND DETERMINATION REPORT Windsor Blue Housing Plat Wetland Delineation RESULTS May 6,2014 3.0 RESULTS 3.1 SITE DESCRIPTION The Study Area is comprised of periodically mowed grass lawn with mature trees. Silver maple(Acer saccharinum)are planted along the outside border of the Study Area,with a mix of honey locust (Gleditsia triacanthos),white ash(Fraxinus americana),white spruce(Picea glauca),and red oak (Quercus rubra)present within the middle of the Study Area. The Study Area slopes from approximately 895 feet mean sea level(msl)on the eastern end of the site to approximately 870 feet msl in the southwestern portion of the site. The Study Area is bordered by Golf Road on the north,Birch Drive to the east,and East Oak Lane along half of the southern boundary.Open fallow land and the Yahara River are present beyond the southwestern corner of the Study Area. Soils mapped on the Property by the NRCS Soil Survey of Dane County include Batavia silt loam(BbB), St.Charles silt loam(ScB),Virgil silt loam(VwA),and Wacousta silty clay loam(Wa)(Appendix A,Figure 2). According to the NRCS List of Hydric Soils for Dane County,the Wacousta series is listed as a hydric soil unit and the Virgil series may contain hydric inclusions. The Wisconsin Wetland Inventory(WWI)map does not identify any wetland within the Study Area, although one wetland area is identified just north of the site(Appendix A,Figure 3). Average precipitation for the investigation area was obtained from the Dane County Regional Airport weather station in Madison,WI(NWS station#W14961)and used for the WETS analysis. Based on the WETS analysis,conditions were wetter than normal(Appendix D). 3.2 WETLANDS No wetlands were identified within the Study Area. Wetland determination data forms were completed for two sample points and are contained in Appendix B. Sample point P1 was completed in mapped hydric soils and in a topographic low spot near the center of a swale where one may expect wetland conditions to develop. Sample point P2 was also placed in a low swale,but within mapped non-hydric soils unit.Photographs of the Study Area and land adjacent to the sample point locations are contained in Appendix C. The sample point locations are shown on Figure 4(Appendix A). 3.3 UPLANDS Uplands within the Study Area consisted of periodically mowed grass lawn with planted trees along the periphery and down the middle of the site. As noted above,two sample points were completed within areas where conditions were likely most suitable for wetland development based on topography and mapped soils;however upland conditions were confirmed. The Study Area was dominated by non- hydrophytic species and was higher in topography than potential wetland areas southwest of the site. Common species seen at sample points and observed throughout included Kentucky bluegrass(Poa pratensis),smooth brome(Bromus inermis),dandelion(Taraxacum officinale),and orchard grass (Dactylis glomerata). Additionally,wetland hydrology and hydric soils were not observed. Stantec 3.4
