P.O. Boz 458 Kimball, MN 55353-0458 (320)398-2705 August 14,2006 Orono Subdivision Loren Butterfield WETLAND DELINEATION REPORT Owner/Applicant: Loren Butterfield Project: Orono Subdivision Wetland Delineation Methodology The use of a multi-parameter approach(vegetation, soil and hydrology)was implemented to delineate a portion of the wetlands occurring at the Orono Subdivision Property in Section 32,Township 118,Range 23,Orono,Minnesota. The Routine On-Site Determination method,as described in the 1987 addition of the Federal Manual for Identifying and Delineating Jurisdictional Wetlands,was used to delineate the site. Wetlands were also classified according to Wetlands and Deepwater Habitats of the United States (FWS/OBS Pub 79/31: Cowardin et al. 1979) and Wetlands of the United States (USFWS Circular 39; Shaw and Fredine 1971). Areas that are dominated by hydrophytic vegetation, meet the hydric soils criteria, and exhibit indications of wetland hydrology are identified as wetland communities. These three technical criteria are mandatory and must be satisfied in making a wetland determination. Field techniques consist of a main transect with a series of soil samples combined with vegetation data, and observations of hydrology to determine wetland boundaries. Each individual lath is generally associated with a series of soil probes(18 inches or greater in depth)that are taken in a line from obvious upland to obvious wetland. Munsell Soil Color Charts are used to determine soil chroma, mottle color and gleying color(when present). If the soil does not meet the hydric requirement,and the site lacks wetland hydrology and dominant hydric vegetation,another sample is taken 1-3 feet toward the wetland until all three requirements are met(under Normal and Undisturbed Conditions). Wetland Plant Indicator Designations Where plant species have been referenced in the text and tables,we have cited the scientific name,common name,and wetland indicator status according to the National List of Plant Species that Occur in Wetlands: North Central, (Region 3). (USFWS Biological Report 88(26.3); May 1988). A plus or minus sign attached to a species' indicator status means that the species falls on the high or low side of the frequency range for its classification. The various indicator categories are as follows: OBLIGATE WETLAND (OBQ: Species occurs almost always (estimated probability >99 %) in wetlands under natural conditions. FACULTATIVE WETLAND (FACW): Species usually occurs in wetlands (estimated probability 67 to 99 %) but occasionally found in non-wetlands. FACULTATIVE (FAC): Species equally likely to occur in wetlands and non-wetlands (estimated probability 34 to 64%). FACULTATIVE UPLAND (FACU): Species usually occurs in non-wetlands (estimated probability 67 to 99 %) but occasionally found in wetlands(estimated probability 1 to 33%). OBLIGATE UPLAND (UPQ: Species occurs almost always (estimated probability >99 %) in non-wetlands under natural conditions. For an area to be a jurisdictional wetland, more than 50 percent of the dominant vegetation from all strata (Herbaceous, Shrub, Sapling, Tree, and Vine) must be OBL, FACW, and/or FAC, under normal and undisturbed conditions. 2006-226wdr.doc Orono Subdivison Loren Butterfield Vegetative Dominance and Strata Dominance refers strictly to the spatial extent of a species that is directly discernible in the field. The most abundant plant species that immediately exceeds 50 percent of the total dominance for a given stratum, plus any additional species comprising 20 percent or more of the total are considered dominant plant species for that stratum. Strata for which dominants are determined include: 1.Tree->5 inches DBH and 20 feet or taller. 2. Sapling-0.4 to<5 inches DBH and 20 ft or taller. 3.Shrub-3 to 20 feet tall including multistemed,bushy shrubs,trees and saplings 4.Vines-includes all woody vines. 5.Herb-includes all herbaceous plants(grass,sedge,forbs,ferns,etc.) National Wetland Inventory The National Wetland Inventory(NWI)is prepared by the U.S. Department of the Interior,Fish and Wildlife Service. NWI maps are prepared primarily by stereoscopic analysis of high altitude aerial photographs. Wetlands were identified on the photographs based on vegetation, visible hydrology, and geography in accordance with Classification of Wetlands end Deepwater Habitats of the United States(FWS/OBS-79/31 December 1979). The aerial photographs typically reflect conditions during the specific year and season when they were taken. In addition, there is a margin of error inherent in the use of the aerial photographs. Thus, a detailed on the ground and historical analysis of a single site may result in a revision of the wetland boundaries established through photographic interpretation. In addition,some small wetlands and those obscured by dense forest cover may not be included on this document. Federal, State and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt,in either the design or products of this inventory,to define the limits of proprietary jurisdiction of any Federal, State or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, State or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may effect such activities.

A site location map is included as Figure 1. Copies of the National Wetland Inventory(NWI)and Hennepin County Soil Survey maps for the area of the project site are included as Figures 2 and 3, respectively. Figure 4 presents the approximate wetland boundary lines delineated as part of this project. The delineation consists of one wetland line with one transect comprised of two soil pits across a portion of the line that best characterizes the wetland. Routine Wetland Determination Data Forms for each wetland transect soil pit can be found in the Appendix. Site Circular 39 Cowardin Designation Type Type A 2 PEMB Wetland Line A and Transect A ye. i. '• Y4. yc The wetland at Transect"TA"is a Type-2, (PEMB)wet meadow.The area is mapped as Type-3,PEMC on the NWI (Figure 2). The location of Line A and Transect A can be found on Figure 4. The boundary of the wetland was staked in the field with pin-flagging and labeled A-1 through A-18.The wetland dominants included Reed Canary Grass,Sedge, and cattail.Upland dominants include Brome Grass,White Clover,Dandelion and Kentucky Bluegrass. The soil that is present in the wetland is mapped in the Hennepin County Soil Survey as L132A Hamel-Glencoe,depressional 0 to 3 percent slopes(Figure 3)of which is included on both the local or national hydric soils list.
