Travis Fristed, PWS (#2360), MN WDC (#1169) Senior Environmental Scientist/Environmental Services Group Manager 1775 Fox Street - Wetland Delineation Report Page 1 ISG Project No. 19-23535 Executive Summary ISG completed a wetland investigation within a 5.49 acre project area in Orono, MN on October 8, 2019 (as shown on the attached Figures). This wetland investigation was performed in accordance with the 1987 US Army Corps of Engineers Wetland Delineation Manual and the 2010 Midwest Regional Supplement, and all applicable supporting documents for areas meeting wetland criteria for a routine wetland delineation in accordance to the MN Wetland Conservation Act and the US Army Corps of Engineers Section 404 Program. Vegetation, soil and hydrology sampling have been completed on all potential wetland areas within the project area. Wetland determinations were based on the three required technical criteria: occurrence of hydric soil, predominance of hydrophytic vegetation, and the presence of one primary and/or two secondary indicators of wetland hydrology. Potential wetland areas (mapped hydric soils, NWI signatures, and low depressional areas) were investigated on-site and delineated as upland. Farmed wetlands that lacked a natural plant community were determined based on the presence of one primary and/or two secondary indicators of wetland hydrology (in accordance with the 87’ Corps Manual Section F- Atypical Situations and Regional Supplement Chapter 5- Problematic Hydrophytic Vegetation). Potential wetland areas (mapped hydric soils, NWI signatures, and low depressional areas) were investigated on-site and delineated as upland. Table 1.

The wetland investigation boundary (or project area) encompasses approximately 5.49 acres near the intersection of Fox St. and CSAH 146 in Orono, Minnesota. The purpose of the wetland investigation is to accurately identify wetland areas onsite so that they can be incorporated into plans for any future development of the property. 1775 Fox Street - Wetland Delineation Report Page 2 ISG Project No. 19-23535 This report is intended to facilitate any regulatory discussions of Wetland Conservation Act and Clean Water Act Section 10/404 permitting for this project. PROJECT LOCATION The project area is located east of the intersection of Fox St. and CSAH 146 in Section 3, T117N, R23W, in the city of Orono, Minnesota (See Figure 1, Appendix A for a location map). The site is located within the Mississippi River – Twin Cities major watershed (20), and the Long Creek minor watershed (20092). The topography of the site slopes east towards an unnamed DNR public waters wetland. Site elevation ranges from approximately 930’ to 952’ above msl. At the time of this delineation, the investigation area was composed of grassland, forested upland, and wetland. SURROUNDING PROPERTIES The project site is located in the outskirts of Orono next to large spaced out lots. Some lots are heavily wooded and others partially wooded. Due to its location moderately spaced single family residences surround the project area. Definitions + Methodology This investigation was performed in accordance with the US Army Corps of Engineers 1987 Wetland Delineation Manual and the 2010 Midwest Regional Supplement, and all applicable supporting documents for areas meeting wetland criteria for a routine wetland delineation in accordance to the Minnesota Wetland Conservation Act and the US Army Corps of Engineers Section 404 Program. The following definitions, diagnostic environmental characteristics, and the methodology used is based on the mandatory technical criteria for the identification and delineation of wetlands. WETLANDS DEFINITION As defined in 33 CFR Part 328, Section 3, the term wetlands is defined as: Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. The frequency and duration of saturation may vary by geographical region, and is largely dependent upon climatic conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands have the following general diagnostic environmental characteristics: 1775 Fox Street - Wetland Delineation Report Page 3 ISG Project No. 19-23535 Hydrophytic Vegetation The wetland vegetation criterion is satisfied when the prevalent vegetation consists of plant species adapted to inundation or substrates periodically deficient in oxygen as a result of prolonged saturation. Specifically, this includes plant communities that under normal circumstances have more than 50% of the composition of the dominant species from all strata ranked with an indicator status as obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC) species. The indicator status for individual plants as defined by the updated 2016 Minnesota National Wetland Plant List are identified and described in the following table: Table 2. Vegetation Indicator Categories Indicator Category Occurrence in Wetlands Obligate (OBL) Almost always Facultative Wetland (FACW) Usually Facultative (FAC) Equally likely to occur in uplands Facultative Upland (FACU) Rarely Upland (UPL) Almost never Hydric Soil A hydric soil is a soil formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part. Examples of hydric soil indicators include: the accumulation of organic matter, low-chroma soil matrices, gleying, redox concentrations, redox depletions, and hydrogen sulfide odor. Wetland Hydrology According to the 1987 manual, wetland hydrology is present when the area is inundated either permanently or periodically at mean water depths less than or equal to 6.6 feet, or the soil is saturated to the surface at some time during the growing season. The Midwest Regional Supplement requires fourteen (14) or more consecutive days of flooding or ponding, or a water table of twelve (12) inches (30 cm) or less below the soil surface, during the growing season at a minimum frequency of five (5) years in ten (10) (50% or higher probability) to satisfy wetland hydrology. The wetland hydrology criterion can be satisfied with observation of one (1) primary hydrology indicator or two (2) secondary hydrology indicators. Potential primary indicators of wetland hydrology may include, but are not limited to: inundation, saturation, water marks, drift lines, sediment deposits, and a thin muck surface. Potential secondary indicators of wetland hydrology may include, but are not limited to: surface soil cracks, drainage patters, saturation visible on aerial imagery, and the FAC-neutral test. 1775 Fox Street - Wetland Delineation Report Page 4 ISG Project No. 19-23535 OFF-SITE METHODOLOGY Map Review Prior to fieldwork, several mapping sources were consulted to identify potential wetland habitats. The sources consulted include the United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI), United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), formerly Soil Conservation Service (SCS) Soil Survey, Minnesota Department of Natural Resources (DNR) Public Waters Inventory (PWI), and United States Geological Survey (USGS) Topographic maps. Areas indicating evidence of potential wetland conditions were evaluated in greater detail through fieldwork. Precipitation Data Analysis Precipitation data from the Minnesota Climatology Working Group and Natural Resources Conservation Service WETS Tables were used in conjunction with the NRCS Method for Evaluating Antecedent Moisture Conditions to determine precipitation conditions under which the investigation was conducted. ON-SITE METHODOLOGY Field Sampling Procedures Sample transects were established in representative transition zones between wetland and upland for each observed plant community. For potential wetland areas greater than five acres in size, a minimum of three transects were established along the baseline wetland boundary for lengths of up to one mile, three to five transects for one to two miles, five to eight transects for two to four miles, and eight or more transects for wetland baseline boundaries that exceed four miles in length. Transect intervals do not exceed 0.5 mile apart from each other. Transects are comprised of two sample points, one sample in upland and one sample point in wetland. A field data sheet was completed describing the dominant soil characteristics (to a minimum of 24 inches below the soil surface), plant communities, and hydrology indicators at the sample point. The presence of water was observed after time (depending on soil characteristics) was allowed for movement of water through the soil substrate. Absolute percent areal cover was recorded for the species that were observed (which may exceed 100% total area due to overlap) and dominance was determined by using the 50/20 rule. Vegetation was sampled within each stratum present at a sample point using the following circular plot sizes: • Trees – 30 ft radius • Saplings and Shrubs – 15 ft radius 1775 Fox Street - Wetland Delineation Report Page 5 ISG Project No. 19-23535 • Herbaceous – 5 ft radius • Woody Vines – 30 ft radius The sample points were marked with 4-foot lathe, photographed, and flagged with surveyor’s tape (if not within an agricultural land use). Other samples were taken at unmarked locations to provide verification of the wetland edge, as needed. Wetland Boundary Delineation The wetland boundaries were determined using changes in topography, dominance of hydrophytic/non-hydrophytic vegetation, hydric soil indicators, and/or hydrology characteristics. Wetland edges were marked with pink “wetland delineation” flags. The wetland edge is considered to be the highest extent of the wetland basin. Areas below the flagged edge satisfy the three required wetland criteria while areas above were lacking in one or more of these criteria. US Army Corps of Engineers Regulatory Guidance Letter 90-6 requires documentation sufficient to allow a reasonably accurate replication of the delineation at a future date. Reasonably accurate is defined as within 0-2 meters accuracy. Precise positions of sample points and the wetland edge have been located by a sub-meter GPS unit and have been included in the wetland delineation drawing or map for this property. Wetland Type Classification Wetlands were classified using Wetland Plants and Plant Communities of Minnesota and Wisconsin (Eggers & Reed 2007), Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, et al, 1979) and Wetlands of the United States (Fish and Wildlife Service Circular 39, Shaw and Fredine 1971). Findings MAP REVIEW The NWI map lists one NWI signature which encompasses a majority of the project area. This NWI signature is listed as a Palustrine Emergent Persistent Seasonally Flooded (PEM1C) wetland. The basin is shown in Figure 2, Appendix A. There is one DNR Public Waters basin located within the investigation area. This basin is an unnamed Public Waters Wetland (27085900). The basin is shown in Figure 2, Appendix A. Soils within the investigation boundary have been mapped by the NRCS along with their hydric classification. The location of each soil unit occurring within the investigation boundary is shown on the Hennepin County Soil Survey map (Figure 3, Appendix A). 1775 Fox Street - Wetland Delineation Report Page 6 ISG Project No. 19-23535 The LiDAR map (Figure 4, Appendix B) illustrates the highest elevations near the western half of the site. Elevations vary within the project boundary, ranging from 952 feet above msl to 930 feet above msl where the public waters wetland. ANTECEDENT PRECIPITATION DATA ANALYSIS The precipitation received in the project area during the previous three months was above the normal range (30-70th percentile) for this area. Prior to the sample date of October 8, 2019, there was above normal precipitation in September, August, and July. Therefore the field work was completed under above normal conditions according to the precipitation worksheet for wetland delineations (Appendix C). FIELD DELINEATION RESULTS Based on the data reviewed and fieldwork conducted, one (1) area was examined for wetland characteristics within the project area. One (1) wetland was ultimately delineated and is further described within this report. The delineated wetland is identified as Wetland A, which includes sample points 1 & 2. One transect was taken along Wetland A’s boundary. Field data forms for each sample point are located in Appendix B. Refer to Figure 6 (Appendix B) for a map of the project boundary, wetland basin, sampling transect, and area. Photos of the wetland basin within the project boundary are included in Appendix C. OTHER AQUATIC RESOURCES The only prominent aquatic resource within the project boundaries is the aforementioned DNR Public Waters and NWI wetland (delineated as Wetland A) that is mapped in the eastern portion of the project area (Figure 2, Appendix A). Wetland A appears to extend off-site to the north, east, and south. Wetland A outlets into Tanger Lake .12 miles southeast of the project area. WETLAND SUMMARY Wetland A Wetland A is a Type 3 Shallow Marsh wetland dominated primarily by cattail. Wetland A is located within the eastern half of the project area at the bottom of a steep hillslope. Wetland A was flagged and GPS’d primarily based off of topography, which was placed at the toe of the hillslope along the forested upland and several feet above the hillslope based off a change in dominant vegetation along the cleared upland area. 1775 Fox Street - Wetland Delineation Report Page 7 ISG Project No. 19-23535 Recommendations Activities impacting or potentially impacting the wetlands identified are regulated through several levels of government in Minnesota: • Federal: US Army Corps of Engineers: Permit Programs under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act • Federal: USDA NRCS: Wetland Conservation Provisions of the 1996 Farm Bill • State of Minnesota: Minnesota Department of Natural Resources: Public Waters Work Permit Program • Local: Local Units of Government (LGU) administer the Minnesota Wetland Conservation Act (WCA) of 1991. Please note that grading, excavating, or filling is not allowed until all necessary permits have been obtained. If wetland impacts are proposed, ISG can assist in the proper steps to acquire the appropriate permit or exemption. By initiating the permit process as soon as possible, potential costly delays to the project may be avoided. 1775 Fox Street - Wetland Delineation Report Page 8 ISG Project No. 19-23535 Data Sources + Literature Cited Cowardin, L.M., V.
