R 23W, Orono, Hennepin County, Minnesota Project Description: Wetland Classification, Identification, Delineation, & Staking Services Dear Mr. Knappenberger: As requested, Svoboda Ecological Resources(SER)visited the above referencedro ert ri1 P P Y on A P 26,.2004 to examine the site for the presence of areas meeting wetland criteria. Criteria for determining jurisdictional wetlands are as described in the 1987 U.S. Army Corps of Engineers Wetlands Delineation 11anual(1987 Manual)as required by the Minnesota Wetland Conservation Act. The project site consists of an open grass and meadow plot with hardwoods located throughout the property. An emergent,vegetation wetland basin lies in the northwest portion of the parcel;'a 'drainage ditch runs from the basin to the southeast dividing the upland areas in two. Remnants from a previously existing home are currently onsite centrally located. Watertown Road borders the property to the north and Old Crystal Bay Road to the east(See Figure 1). METHODS National Wetland Inventory (NWI) maps, Soil Survey of Hennepin County maps, Minnesota Department of Natural Resources(DNR)Protected Waters maps,and aerial photographs from 2003 were reviewed prior to the site visit to identify areas of concern.. Areas illustrating evidence of wetland conditions were examined in greater detail during the field survey. Vegetation, soils and hydrology were examined(as outlined in'the 1987 Manual) and used to characterize wetland types and determine wetland boundaries. Sample transects were established in representative wetland-to- upland transition zones in order to characterize the vegetation,soils,and hydrology of the site.. The transects consist of one representative upland sample point and one representative wetland sample point. Information obtained from the sample points can be found on the field data sheets located in Appendix A. , Wetland boundaries were marked at the site by blaze-orange"wetland boundary"flagging attached to 4-fdot wooden lath. The "wetland boundary" is considered to be the topographically highest extent of the wetland basin; areas below the staked boundary met the'three required wetland criteria while areas above were lacking in one or more of these criteria. 2477 Shadywood Road - Excelsior,MN 55331 (952)471-1100 (Office) - (952)471-0007 (-Fax) , Wetland classification followed methods described by Cowardin et at. (1979) and used in the NWI 0 completed by the U.S. Fish and Wildlife Service. The Circular 39 classification(Shaw and Fredine 1956) is also given. The indicator status of plants, as described in Appendix B, was determined using the National List of Plant Species That Occur in Wetlands - illtinnesota (Reed 1988). RESULTS AND DISCUSSION The NWI map (Excelsior Quadrangle) indicates one wetland basin located on the subject property (Figure 2). The wetland basin is classified as a palustrine(P)type wetland with broad leaf deciduous scrub-shrub vegetation (SS 1) and a seasonally flooded moisture regime (C), or a Type 6 (PSS 1C) wetland on the NWI map. Upon completion of inspection it was determined that Basin 1 is a palustrine (P) type wetland exhibiting emergent vegetation (EM) with broad leaf deciduous scrub- shrub vegetation (SSI) and a seasonally flooded moisture regime (C) being partially drained or ditched (d) or a Type 2/3/6 (PEM/SS 1 Cd) wetland. Basin 1 is located within a Hamel loam (Ha) mapped soil type. The Soil Survey of Hennepin County, Figure 3,indicates three soil series present on subject property; Glencoe silty clay loam(Gc), Hamel loam(Ha),and Lester loam(LrB),Appendix C. Glencoe silty clay loam and Hamel loam are classified as hydric soils(SCS Hydric Soils ofthe United States). The DNR Protected Waters map of Hennepin County, Figure 4, indicates no protected wetland basins within the subject property. SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit and delineated the edge of one basin Basin 1 as being jurisdictional wetland. Detailed g ( ) gJ soils, vegetation and hydrology data for this wetland is provided in the data sheets of Appendix A. The drainage ditch was also delineated but may be incidental wetland subject to verification by the Local Government Unit(LGU). Incidental wetlands are not subject to regulation SER personnel delineated Basin 1 in April 2004,based on the presence of hydric soils,hydrophytic vegetation, and wetland hydrology. SER determined Basin 1 to be a PEM/SS 1 Cd type wetland. Basin 1 mainly consists of reed canary grass (Phalaris arundinacea, FACW+), lake-bank sedge (Carex lacustris, OBL),and broad-leaved cattail(Typha latifolia,OBL) species. Basin 1 is located within a Hamel loam (Ha)mapped soil unit. Basin 1 is a topographic depression within the parcel. Overland flow from roadside runoff and adjacent uplands collects in Basin 1. The main factor influencing the wetland edge determination was the transition of dominance between hydrophytic and upland vegetation,the presence of hydric soils, and topography. No water was observed in the i boreholes at a depth of 20" but due to substantially below normal precipitation in 2003 absence of water could be expected. A drainage ditch runs to the southeast from Basin l; as it nears the southern property boundary it turns to the east running along the property boundary edge. This ditch then enters into a drainage g AWN ditch located along the west side of Old Crystal Bay road. Several soil borings were taken within the Ell ditch, most borings showed water within 6" of the soil surface. A housing structure previously existed in the Area A location,the house had been removed and the basement dugout prior to the site visit. The pit where the basement was located is currently holding water and a few species of hydrophytic vegetation were observed growing. Area A should be considered non jurisdictional lli wetland since the basement pit had recently been dug. SER observed construction debris placed along the east side of Basin 1, it appeared that these materials had been placed some time ago. CONCLUSIONS SER examined the subject property and delineated one wetland, which exhibited a dominance of hydrophytic vegetation, hydric soils and wetland hydrology. Overland flow from adjacent uplands collects in Basin 1. Basin 1 is a Type 2/3/6 PEM/SS 1 Cd wetland, located within the subject property.
