OVERVIEW The 2.3-acre 2640 Watertown Rd Site was inspected on July 13th, 2021, for the presence and extent of wetland. The property was located in Section 33, Township 118 North, Range 23 West, City of Orono, Hennepin County, Minnesota. The site was situated adjacent to the northeast side of the intersection of Golden View Drive and Watertown Road (Figure 1). The property corresponded to Hennepin County PID# 3311823430004. The 2640 Watertown Rd Site consisted of a disturbed area that was previously a house and yard, two wetlands, woodland, and a meadow/field with scattered trees and uneven topography. It is suspected that the southern third of the site, where the house and yard was, contains fill and there is also an old road bordering the eastern boundary. Topography of the site sloped from 1036 ft MSL on the southern portion of the site down to 1030 to 1032 ft MSL within the wetlands. Surrounding land use is residential. Two wetlands were delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown on Figure 2. Figure 2 does not represent an 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 under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence under Section 404 of the Federal Clean Water Act from USACE. 3. METHODS Wetlands were identified using the Routine Determination method described in the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest 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 Landform. 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 2640 Watertown Rd Site, Orono Wetland Delineation Report 3 Conservation Service (NRCS) in cooperation with the National Technical Committee for Hydric Soils, Version 8.1, 2017). Mapped soils are separated into five classes based on the composition of hydric components and the Hydric Rating by Map Unit color classes utilized on Web Soil Survey. The five classes include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric components), Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric (1 to 32 percent hydric components), and Non-Hydric (less than one percent hydric components). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2016 National Wetland Plant List (U.S. Army Corps of Engineers 2016. National Wetland Plant List, version 3.3, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH). 4. RESULTS 4.1 Review of NWI, Soils, Public Waters, and NHD Information The National Wetlands Inventory (NWI) (Minnesota Geospatial Commons 2009-2014 and U.S. Fish and Wildlife Service) showed one wetland within the site boundaries (Figure 3). The Soil Survey (USDA NRCS 2015) showed Hamel – Glencoe complex (Predominantly Hydric) as the hydric soil type mapped within the site boundaries. Soil types mapped on and near the property are listed in Table 2 and a map showing soil types is included in Figure 4. Table 2. Soil types mapped on 2640 Watertown Rd Site Symbol Soil Name Acres % of Area % Hydric Hydric Category L132A Hamel-Glencoe complex, 0 to 2 percent slopes 1.7 76.0 90 Predominantly Hydric L22D2 Lester loam, 10 to 16 percent slopes, moderately eroded 0.4 16.9 0 Non-Hydric L25A Le Sueur loam, 1 to 3 percent slopes 0.2 7.0 15 Predominantly Non- Hydric L37B Angus loam, 2 to 6 percent slopes 0.0 0.1 5 Predominantly Non- Hydric The Minnesota DNR Public Waters Inventory (Minnesota Department of Natural Resources 2015) showed no DNR Public Waters, Wetlands or Waterways within 1000 feet of the site (Figure 5). The National Hydrography Dataset (U.S. Geological Survey 2015) showed one Lake/Pond approximately 300 feet east of the site and one stream/river 1,000 feet south of the site (Figure 6). 2640 Watertown Rd Site, Orono Wetland Delineation Report 4 4.2 Wetland Determinations and Delineations Potential wetlands were evaluated during field observations on July 13th, 2021. Two wetlands were identified and delineated on the property (Figure 2). Corresponding data forms are included in Appendix B. The following descriptions of the wetlands and their adjacent uplands reflect conditions observed at the time of the field visit. Herbaceous vegetation was actively growing at the time of the wetland delineation. Precipitation conditions were normal based on the three-month antecedent precipitation data and drier than the normal range based on available 30-day rolling total precipitation (Appendix C). Wetland 1 was a Type 1/3 (PEM1A/PEM1C) seasonally flooded basin dominated by reed canary grass. The wetland was dry. Secondary hydrology indicators of FAC-Neutral Test and Geomorphic Position were observed along the wetland fringe. Adjacent upland consisted of woodland dominated by a canopy of boxelder and an understory dominated by lady fern, with lesser amounts of prairie fleabane, rough bedstraw, stinging nettle, and ground ivy. Primary and secondary hydrology indicators were not observed on the upland. The wetland boundary corresponded with a topographic rise along a transition of changing plant communities. The wetland was shown as a PEM1A on the NWI map and fell in an area mapped as Hamel – Glencoe complex (Predominantly - Hydric) on the soil survey. It is bordered by an old road built on an embankment on the east, and there is a mound in the northwest, directly outside of the wetland boundary. A drainage pipe (possible sump pump) discharged at the southwestern corner of the wetland. No outlets were observed. Wetland 2 was a Type 1 (PEM1A) seasonally flooded basin dominated by reed canary grass with scattered green ash and American elm, and lesser amounts of yellow rocket and false wood nettle. The wetland was dry. Secondary hydrology indicators of FAC-Neutral Test and Geomorphic Position were observed along the wetland fringe. Adjacent upland consisted of a meadow/field with a canopy of scattered trees and an understory dominated by Kentucky bluegrass with lesser amounts of Virginia creeper, and American bugleweed. Other species observed include bittersweet nightshade, stickseed, sticky willy, Canada goldenrod, prairie fleabane, Canada thistle, lady fern, wild grape, and rough cinquefoil. Primary and secondary hydrology indicators were not observed on the upland. The wetland boundary corresponded with a topographic rise along a transition from a wetland to upland plant community. The wetland was shown as a PEM1A on the NWI map, and fell in an area mapped as Hamel – Glencoe complex (Predominantly - Hydric) on the soil survey. Wetland 2 extended offsite to the north. 4.3 Other Areas No other areas with hydrophytic vegetation or wetland hydrology were observed on the site. No other areas were shown as hydric soil on the soil survey or as wetland on the NWI map. 2640 Watertown Rd Site, Orono Wetland Delineation Report 5 4.4 Request for Wetland Boundary and Jurisdictional Determination 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 under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence under Section 404 of the Federal Clean Water Act. 2640 Watertown Rd Site, Orono Wetland Delineation Report 6 5. CERTIFICATION OF DELINEATION The procedures utilized in the described delineation are based on the U.S. Army Corps of Engineers 1987 Wetlands Delineation Manual as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act.
