WETLAND DELINEATION REPORT <br /> Silver View Pond Restoration <br /> Methods <br /> October 26, 2023 <br /> 2.0 METHODS <br /> 2.1 WETLANDS <br /> Wetland delineations were based on the criteria and methods outlined in the Corps of Engineers Wetlands <br /> Delineation Manual,Technical Report Y-87-1 (1987)and subsequent guidance documents(USACE 1991 a, <br /> 1991b, 1992), and applicable Regional Supplements to the Corps of Engineers Wetland Delineation <br /> Manual. <br /> The wetland delineation involved the use of available resources to assist in the assessment such as U.S. <br /> Geological Survey (USGS) topographic maps, U.S. Department of Agriculture Natural Resources <br /> Conservation Service (NRCS) soil survey, U.S. Fish and Wildlife Service (USFWS) National Wetlands <br /> Inventory (NWI) mapping, MNDNR Minnesota NWI Update mapping, MNDNR Protected/Public Waters <br /> mapping, and aerial photography. <br /> On-site wetland delineations were made using the three criteria (vegetation, soil, and hydrology) and <br /> technical approach defined in the USACE 1987 Manual and applicable Regional Supplement.According to <br /> procedures described in the 1987 Manual and applicable Regional Supplement, areas that under normal <br /> circumstances reflect a predominance of hydrophytic vegetation, hydric soils, and wetland hydrology(e.g., <br /> inundated or saturated soils)are considered wetlands. <br /> As recent weather patterns influence the visibility and presence of some wetland hydrology indicators, the <br /> antecedent precipitation in the three months leading up to the field investigation was reviewed.The current <br /> year's precipitation data were compared to the most recent long-term (30-year) precipitation averages and <br /> standard deviation to determine if precipitation was normal, wet, or dry for the area using the Antecedent <br /> Precipitation Tool (APT)as developed by the USACE. <br /> Wetland boundaries were identified and flagged using pink"WETLAND DELINEATION"flags and wetland <br /> sample points were identified and flagged using lath with orange flagging tied to it. Both wetland boundaries <br /> and sample points were surveyed with a Global Positioning System (GPS) capable of sub-meter accuracy <br /> and mapped using Geographical Information System (GIS) software. <br /> 2 <br />
