Orono substation site located at 3960 Sixth Avenue North, Orono, Hennepin County, Minnesota 55356 (heretofore referred to as the Site). The wetland delineation was conducted to assist Xcel Energy, Inc. with planning expansion of the existing Orono substation facility. Minnehaha Creek Watershed District (MCWD) is the Local Governmental Unit (LGU) that administers the Minnesota Wetland Conservation Act (WCA). This delineation report provides the required documentation for wetland boundary determinations in conformance with the United States Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory, Waterways Experiment Station, 1987) and the Interim Regional Supplement to the USACE Wetland Delineation Manual: Midwest Region(US Army Engineer Research and Development Center, 2008). On behalf of Xcel Energy, Inc., Westwood respectfully requests that the MCWD, as the LGU, provide written confirmation that the delineated wetland boundary shown on the attached Delineated Wetland Boundar ��map�E�chibit 5) is acceptable for local administration of the WCA. Please consider this report a formal Wetland Boundar,�and Type Determination request pursuant to Minn. Rules 8420.0405. Westwood also requests that the USACE provide written confirmation that the delineated wetland boundary(Exhibit 51 is acceptable for Clean Water Act permittin�purposes. 2.0 SITE LOCATION AND DESCRIPTION The Site is located in the SW '/ of the SW '/ of Section 29 and the NW '/ of the NW '/ of Section 32, Township 118 North, Range 23 West, City of Orono, Hennepin County, Minnesota (Eachibit 1). The property is bounded by State Highway 12 (Wayzata Boulevard) and the Burlington Northern Santa Fe Railroad to the north, County Road 6 (6`�'Avenue North)to the south and east, with a residential property boundary to the west. The approximately 16-acre Site consists of an existing substation in the southwest corner of the property that is surrounded by open meadow with scattered trees. The remainder of the Site is comprised of wetland. Adjacent land use consists of large-lot, single-family homes to the west and south, wetland to the north, and a highway interchange to the east. 3.0 WETLAND DELINEATION METHODOLOGY Prior to delineating wetland boundaries in the field, Westwood reviewed National Wetland Inventory(NWI) mapping (Exhibit 2),the Natural Resource Conservation Service(NRCS) Soil Survey Geographic database (SSURGO) for Hennepin County(2007) (E�ibit 3),the Minnesota Department of Natural Resources (MnDNR) Public Waters and Wetlands Inventory (PWI) for Hennepin County(Ea�hibit 4), and aerial photography for the site location. On June 10, 2010, Westwood delineated the wetland using the level two routine determination method set forth in the USACE Wetlands Delineation Manual (Environmental Laboratory, Waterways Experiment Station, 1987) and the supplemental methods set forth in the Interim Regional Supplement to the USACE Wetland Delineation Manual: Midwest Region(US Army 1 Wetland Delineation Report—Orono Substation Expansion Project July 2, 2010 Engineer Research and Development Center, 2008). Methods included establishment of sampling transects in a representative transition zone of the identified wetland. Each transect consisted of one sampling point in upland and one point in wetland. Soils, vegetation, and hydrology data were recorded on data forms and are included in Appendix A of this report. Species dominance for vegetation measurements was based on the percent coverage visually estimated within a 30-foot radius of the sample point location for the tree and vine layers, a 15- foot radius for the shrub layer, and a five-foot radius for the herbaceous layer. Wetlands were classified according to Wetlands of the United States (U.S. Fish and Wildlife Service Circular 39; Shaw and Fredine; 1971) and Wetlands and Deepwater Habitats of the United States (FWS/OBS Publication 79/31; Cowardin et. al. 1979) (see the Classification Systems Table in Appendiac B). Common names and scientific names for vegetation identified in this report and on the attached data forms generally correspond with the nomenclature used in the National List of Plant Species that Occur in Wetlands: North Central(Region 3) (USFWS, Reed, 1988). Wetland boundaries were located using a Trimble GeoXT sub-meter accuracy global positioning unit (GPS). Wetland boundary points were then post processed using Trimble Pathfinder Office software to ensure sub-meter accurate GPS coordinates. 4.0 RESULTS 4.1 Mapping NWI mapping(Exhibit 2) depicts one Type 3 (PEMCd) wetland on the northern and eastern portions of the Site and is consistent with the delineated wetland boundary. The NRCS SSURGO for Hennepin County indicates that the soils listed below are mapped within the Site (E�ibit 3). Klossner soils(depressional), Hougton and Muskego soils (depressional), and Hamel-Glencoe(depressional) complex soils are listed as hydric in Hydric Soils of Minnesota, revised December 1995. All others are indicative of uplands. The distribution of hydric soils in NRCS mapping is consistent with the delineated wetland boundary. Soil Map Unit Name Hvdric? Klossner soils, depressional, 0 to 1% slopes (L49A) Yes Houghton and Muskego soils, depressional, 0 to 1% slopes (LSOA) Yes Hamel-Glencoe, depressional, complex, 0 to 3% slopes (L132A) Yes Lerdal loam, 1 to 3% slopes (L35A) No Lester-Kilkenny complex, 6 to 12% slopes, eroded(L41 C2) No Hamel overwash-Hamel complex, 1 to 4% slopes (L36A) No Angus-Kilkenny complex, 2 to 6% slopes (L40B) No Angus loam, morainic, 2 to 5% slopes(L37B) No The MnDNR PWI (Eachibit 4) for Hennepin County depicts the north part of Public Water Wetland (27-916V� covering most of the Site, with a second part off of the Site to the 2 Wetland Delineation Report—Orono Substation Expansion Project July 2, 2010 south, south of County Road 6. The MnDNR PWI apparently overstates the area covered by wetland 27-916W within the Site as it is depicted in areas designated as upland during the field review. E-mail correspondence with MnDNR Area Hydrologist John Gleason on June 23, 2010 found that an Ordinary High Water Level(OHV� was established for wetland 27-916W in September, 1998. The OHW for the north part of 27-916W(within the Site) is 963.1 mean sea level(msl) and 963.9 msl for the south part. 4.2 Delineated Wetland Descriptions Westwood completed a wetland delineation on the Site and identified one Type 3 (PEMCd) shallow marsh(Wetland A), approximately 13.5 acres of which lies within the property boundary(E�ibit 5). The wetland extends west of the subject property and is part of a larger wetland complex from which it was historically severed by Wayzata Boulevard and the Burlington Northern Santa Fe Railroad grade to the north and County Road 6 to the south. Two transects were completed along the southern wetland boundary. Dominant wetland vegetation included reed canary grass, common reed grass and cattail with lesser amounts of box elder, spotted touch-me-not, stinging nettle, black willow, red- osier dogwood, quaking aspen, river-bank grape, Virginia creeper, and sedge. Upland vegetation was dominated by Canada goldenrod, Kentucky bluegrass, smooth brome, box elder, and prickly ash with lesser amounts of common buckthorn, tatarian honeysuckle, leafy spurge, smooth sumac, bird's-foot trefoil, Canada thistle, and scattered spruce and pine trees. Soils at the wetland sample point locations were generally lOYR 2/lwith approximately 5% lOYR 4/4 concentrations. Soils met the A4 field indicator for hydric soils (Hydrogen Sulfide). Primary indicators of wetland hydrology included a high water table and saturation observed within 12 inches of the soil surface. Soils at upland sample locations were without redoximorphic features and no primary or secondary indicators of wetland hydrology were observed. Detailed data collected for this wetland are provided on the attached data forms in Appendiat A. 4.3 Wetland Buffers According to current MCWD Rule D, wetlands greater than five acres in size require a 35- foot buffer. MCWD Rules for wetland protection are currently being revised. Assuming the proposed draft Wetland Protection Rule is adopted and implemented, the buffer width will be determined based on the functions and values of the wetland using the MCWD's Functional Assessment of Wetlands (MCRAM) or the Minnesota Routine Assessment Methodology(MnRAM). According to Becky Houdek with MCWD, Wetland A was classified as a Manage 2 wetland in 2001 using the MCRAM. As a Manage 2 wetland, base buffer widths would be 30-feet with a minimum applied bufFer width of 24-feet should a permit application be submitted after the Wetland Protection Rule is implemented. 3 Wetland Delineation Report—Orono Substation Expansion Project July 2, 2010 5.0 CONCLUSIONS Westwood delineated and flagged one Type 3 (PEMCd) wetland within the Site totaling approximately 13.5 acres. The delineated wetland corresponded to an NWI-mapped PEMCd wetland and areas of mapped hydric soil(Klossner, Houghton and Muskego, and Hamel-Glencoe). The PWI mapping of DNR Public Waters Wetland 27-916W indicated Wetland 27-916W extending into areas that were determined to be upland as a result of the field delineation. Westwood recommends that the MnDNR be requested to verify that the OHW of 27-916W does not extend beyond the delineated boundary. This can be done as part of the Technical Evaluation Panel(TEP)review of the delineation. Westwood requests that MCWD, as the LGU, provide written confirmation to Xcel Energy, Inc. that the delineated wetland boundaries shown on the attached Wetland Boundaries map (Ea�hibit 5) are acceptable for local administration of the WCA and MCWD Rules. A completed WCA Application for Approval of Wetland Type and Boundary form accompanies this request to facilitate the WCA wetland boundary and type determination request. Westwood also requests that the USACE provide a preliminary jurisdictional determination (JD) and formal wetland boundary determination for Wetland A. A completed Request for Corps of Engineers Wetland Delineation Review form accompanies this request to facilitate the wetland boundary and preliminary jurisdiction determination request. 4 Wetland Delineation Report—Orono Substation Expansion Project July 2, 2010 6.0 LITERATURE CITED Cowardin, L.M. , V.M.
