TI 4J.cnit•7 ■'•••< <br />This project is scheduled to begin in the spring of 1998 and be completed by the fall of 1998. <br />During construction, roadway usage to access driveways of local residents will be maintained. <br />Roadway users traveling through the area will be detoured. <br />WETLAND DELIiVEATION REPORT <br />WETLAND DELINEATION METHODOLOGY <br />^ Wetlands were delineated in accordance with the 1987 United States Army Corps of Engineers <br />(USAGE) Wetland Delineation Manual. Wetland boundaries that were within 200 feet of the <br />proposed construction limits were delineated, staked and surveyed. Wetland boundaries were <br />delineated and staked in the field on May 8, and May 15, 1997. Additional field woilc was done on <br />June lO-l 1,1997, to verify information regarding hydrology, soils and vegetation. Wetland stakes <br />were surveyed by a Hennepin County Survey crew in May, and June, 1997. Wetland classifications <br />are based on the United States Fish and Wildlife Service (USFWS) publications Wetlands and <br />Deepwater Habitats of the United States (Cowardin, 1979) and Wetlands of the United States <br />(Circular 39). Soil colors are described in accordance with Munsell Soil Color Charts (1992 <br />Revised Edition). <br />Wetland Descriptions <br />Ten wetland basins (Plan Sheet 2) were delineated along CSAH 6 between a point 750 feet <br />(228 meters) west of Townline Road and a point 375 feet (114 meters) east of Orchard.Paik Road. <br />The data forms for these delineations are attached to this report (Appendix A). Two additional <br />basins near the eastern end of the project were also delineated but are beyond the construction limits <br />of the project and are not impacted. Descriptions for these two wetland basins are not included in <br />this report Two additional sites within the project corridor were investigated and determined not to <br />be wetlands (Plan Sheet 2). Descriptions of these areas are included in this report The data forms <br />for these two determinations are also included in Appendix A. The National Wetland Inventory <br />and the Minnesota Department of Natural Resources (MDNR) Protected Waters and Wetland <br />Inventory for the project area are shown in Figures 1 through 3. The Hennepin County Soil Survey <br />and USGS topographic map for the project area are shown in Figures 4 through 7. Aerial <br />photographs of the project area (Figures 8-11) are also included as part of this application. <br />Wetland #IN (WLIN) <br />WLIN is a type 2/1L/R4 wetland (PEMB/PFOl A). The dominant vegetation is reed canary grass <br />(Phalaris arundinacea), boxelder (Acer negundo) and green ash (Fraxinus pennsylvanica). Soils are <br />described as Hamel Loam (lOYR 3/1). Redoximorphic features were not observed in the wetland <br />fnnge. Wetland boundaries are sharply defined and were established primarily on elevation and <br />hydric soil indicators (Transect Tl, Appendix A). <br />WeUand#lS(WLlS) <br />WLIS is a type 2 (PEMB) wetland dominated by reed canary grass (Phalaris arundinacea). <br />Wetland boundaries are sharply defined by the toe of slopes of the existing road fill. Soils are <br />mapped as Hamel loam (lOYR 3/1). Field samples indicated that the fiinge area resembled Dundas <br />silt loam (lOYR 3/1). Redoximorphic features (mottles) were present at two sites (Tl-1, Tl-2) <br />along a transect perpendicular to the northern wetland boundary. Mottles at Tl-1 are distinct, very
