The purpose of this study was to delineate and map the extent of all wetlands/Waters of the United States (“Water”), including wetlands under forensic conditions. The site is located in the study area. The study area is located on 3.16 acres, west of the “Y” intersection where California Highway 89 and 28 converge in Tahoe City, Placer County, California. The study area is contained within a 332 acre watershed which flows to the Truckee River near the terminus of Lake Tahoe. The area was composed gentle sloping terrain ranging 7.5% over the entire study area. The topography slopes toward California State Highway 89 to the east. A small area along the westerly boundary is moderately steep with 22% slopes that transform to relatively flat terrain having a 3.5% slope.
7Q10 conducted on-site evaluations. A study of existing landforms as well as associated vegetation, hydrology and soil conditions was initially conducted to identify areas that would likely contain wetland and aquatic habitats. These areas were classified using the U.S. Fish and Wildlife Service’s Classification System for Wetland and Deepwater Habitats. The landward extent or boundary of these habitats was further defined using methodology currently in use by the U.S. Army Corps of Engineers.
