PROJECT LOCATION The project area is located north of Northern Ave and south of Togo Road in Section 17, T117N, R23W, in the city of Wayzata, Minnesota (See Figure 1, Appendix A for a location map). The site is located within the Upper Mississippi River basin, the Mississippi River (twin cities) sub-basin (07010206), and the Minnehaha Creek watershed. The site elevation ranges from approximately 950' above msl at a very small portion on the southeast corner of the project area to 934' above msl in the lowland area centered within the project area. SURROUNDING PROPERTIES The project site is located in a generally suburban area of Wayzata, MN. Most of the surrounding residences consist of wooded or partially wooded lots. Shadywood Road is the main transportation route and is located 25 feet east of the project area. Lake Minnetonka (Crystal Bay) is located approximately 600 feet east of the project area. The investigation area is adjacent to Togo Road on the north and Northern Ave to the south. Definitions + Methodology This investigation was performed in accordance with the US Army Corps of Engineers 1987 Wetland Delineation Manual and the 2010 Midwest Regional Supplement, and all applicable supporting documents for areas meeting wetland criteria for a routine wetland delineation in accordance to the Minnesota Wetland Conservation Act and the US Army Corps of Engineers Section 404 Program. The following definitions, diagnostic environmental characteristics, and the methodology used is based on the mandatory technical criteria for the identification and delineation of wetlands. WETLANDS DEFINITION As defined in 33 CFR Part 328, Section 3, the term wetlands is defined as: Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. The frequency and duration of saturation may vary by geographical region, and is largely dependent upon climatic conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands have the following general diagnostic environmental characteristics: Hydrophytic Vegetation The wetland vegetation criterion is satisfied when the prevalent vegetation consists of plant species adapted to inundation or substrates periodically deficient in oxygen as a result of 3635 Togo Road, Wayzata MN- Wetland Delineation Page 3 ISG Project No. 17-20520
