Trott Brook North Property,Ramsey Wetland Delineation Report Table 1. Site PIDs- Trott Brook North Parcel ID Address Size (ac) 10-32-25-21-0002 -- 7.01 10-32-25-22-0002 7040 173rd Ave NW 7.46 10-32-25-22-0003 -- 48.74 09-32-25-11-0001 -- 38.3 09-32-25-14-0001 -- 38.78 09-32-25-13-0001 -- 32.69 09-32-25-42-0003 -- 24.14 Total 197.12 Eight (8) wetlands were delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown on Figure 2. Figure 2 does not represent and official survey. Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for: (1) a wetland boundary and type determination approval from the Lower Rum River WMO under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence under Section 404 of the Federal Clean Water Act from the U.S. Army Corps of Engineers (USACE) along with Approved Jurisdictional Determinations (AJDs) for Wetlands 1, 2, 3, 7, 7A, 7b, and 8 and the ephemeral gully. 3. METHODS Wetlands were identified using the Routine Determination method described in the Corps of Engineers ineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and Northeast Region (Version 2.0) as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetland that met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were marked with pin flags that were subsequently located by surveyors with Carlson McCain. Figure 2 does not constitute an official survey product. Soils, vegetation, and hydrology were documented at a representative location along the wetland- upland boundary. Plant species dominance was estimated based on the percent aerial or basal coverage visually estimated within a 30-foot radius for trees and vines, a 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. Soils were characterized to a minimum depth of 24 inches (unless otherwise noted)using a Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources 3
