1400 Bracketts Point Road No Wetlands Determination Report <br />2 <br />2. OVERVIEW <br /> <br />The 12.72-acre property at 1400 Bracketts Point Road was inspected on September 27, 2017 for <br />the presence and extent of wetland. The property was located in the SW ¼ of Section 11, <br />Township 117 North, Range 22 West, City of Orono, Hennepin County, Minnesota. The site was <br />situated south of Shoreline Drive (CSAH 15) on a peninsula that juts out into Lake Minnetonka <br />(Figure 1). The property corresponded to Hennepin County PID 11-117-23-32-0020. <br /> <br />The site included a single residential estate with a long, paved driveway, a large home, a <br />maintenance shop, greenhouse, tennis court, veranda, swimming pool, and landscaped planting <br />beds. The southern portion of the site included three storm sewer inlets to enhance drainage and <br />a 4- to 6-foot high retaining wall was aligned along the south boundary of the site. The majority <br />of the site consisted of manicured lawn with several large sugar maple, green ash, red oak, silver <br />maple, white spruce, blue spruce, white cedar, and other trees. The east and west edges of the <br />property dropped relatively steeply to the edge of Lake Minnetonka and the lakeshore was lined <br />with riprap. Site topography was highest at the primary building site where the elevation reached <br />956 feet above msl, and lowest at the edge of Lake Minnesota where the elevation was near 926 <br />feet. <br /> <br />The property was bordered on the east and west by Lake Minnetonka and the north and south by <br />large residential lakeshore lots. <br /> <br />No wetlands were delineated within the site boundaries. One sample point location, storm sewer <br />inlets, the retaining wall location, and existing conditions are shown on Figure 2. <br /> <br />Appendix A includes a Joint Application Form for Activities Affecting Water Resources in <br />Minnesota, which is submitted in request for concurrence with this No Wetlands Determination <br />under: (1) the Minnesota Wetland Conservation Act (WCA), and (2) Section 404 of the Federal <br />Clean Water Act. <br /> <br /> <br />3. METHODS <br /> <br />The property was reviewed for wetlands using the Routine Determination method described in <br />the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) <br />and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest <br />Region (Version 2.0) as required under Section 404 of the Clean Water Act and the Minnesota <br />Wetland Conservation Act. <br /> <br />Soils, vegetation, and hydrology were documented at the location on the property that was most <br />likely to support wetland. Plant species dominance was estimated based on the percent aerial or <br />basal coverage visually estimated within a 30-foot radius for trees and vines, a 15-foot radius for <br />the shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. <br /> <br />Soils were characterized to a minimum depth of 24 inches (unless otherwise noted) using a <br />Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used
